The United States possesses the single largest oil formation found anywhere on Earth.

………..and there is a good chance you’ve never heard of it.

The formation I'm referring to is around 40 times larger than the Permian Basin, a reserve that has transformed American energy production over the past two decades.

It is over 20 times the size of Saudi Arabia’s Gwhar, the largest conventional onshore oil field ever discovered.

The resource I'm referring to is on an altogether different scale. A geological formation estimated to contain somewhere between three and four trillion barrels of oil.

No other oil formation comes close.

At the cross section between Colorado, Utah and Wyoming is preserved the greatest accumulations of hydrocarbons ever assembled by nature.

It is hard to imagine how nature managed to create something on such a scale. To answer that, we have to travel back millions of years to a mid western America that was not an arid desert but a vast chain of freshwater lakes.

Through a quirk of geology the landscape was preparing to lay down the greatest hydrocarbon accumulations in Earth’s history. Around 70 million years ago, tectonic forces were crumpling the western margin of North America, uplifting the Rocky Mountains and buckling the earth’s crust into broad intermountain basins. For those who want to know more, this event was called the Laramide Orogeny.

As the Rocky Mountains rose, many of these ancient basins became lakes, enclosed by mountains, trapped, they became worlds unto themselves.

Every spring, great swathes of microscopic algae would bloom across the water. They lived briefly, perhaps only days, harvesting sunlight through photosynthesis. Their microscopic existence was relatively meaningless yet collectively they performed one of the most miraculous acts in nature. They gathered energy that had travelled over ninety million miles from the Sun and locked it inside living matter.

Then they died.

Ordinarily, that would have been the end of the story. Bacteria would have consumed their remains, most of the stored energy would have returned to the atmosphere, and the great cycle of life would have continued.

But these lakes were different.

Their deeper waters were starved of oxygen and light. Life struggled. The organisms that would normally recycle this organic material into the environment could not keep pace. Instead, countless generations of microscopic algae settled onto the lake floor, where they became buried beneath fine layers of clay and silt before decomposition could take hold.

One season became another, and another, then another. This simple process continued for over 10 million years. Each individual layer was thin. A few millimetres. Sometimes less. No single season particularly mattered. No single bloom transformed the landscape. Yet geological time possesses immense patience. What is insignificant over a lifetime becomes extraordinary over billions of microbial lifetimes.

Layer settled upon layer. Summer followed summer. Over tens of millions of years the work of organic preservation continued while continents shifted, mountain ranges rose and species appeared and vanished from the Earth.

Eventually those layers of sediments hardened into stone.

Today, when you stand before an exposed cliff within the region, you are looking at rock, yes, but also time, arranged in horizontal bands that stretch across the landscape like the pages of an ancient script. Every layer tells a geological story written across the American West.

From a distance they appear as repeating bands of grey, brown and cream. Up close they reveal themselves as the accumulated memory of an ancient world. The individual seasons remain visible to those who know how to read them.

In my last article; ‘The Burning Question”, I explored the journey by which sunlight became chemical energy. This happens to be the greatest repositories of that ancient solar inheritance ever assembled. Those great blooms of microscopic algae were not simply growing. They were continuously harvesting sunlight and storing it, forcing oxygen and carbon dioxide into organic matter, one generation after another, until geology inherited the task that biology had begun.

Those ancient, landlocked lakes eventually left behind a formation stretching across twenty-five thousand square miles of Colorado, Utah and Wyoming, their layered sediments reaching hundreds of metres in thickness in places. Modern estimates suggest that these rocks contain the equivalent of somewhere between three and four trillion barrels of shale oil locked within their finely laminated structure. More than twice the proven oil reserves of the planet.

Measured purely by the amount of organic material preserved beneath the Earth’s surface, within this shale rock formation lies an energy inheritance so vast that concerns about depletion, energy security and declining production seem irrelevant.

I said at the start of this article that the United States possesses the single largest oil formation found anywhere on Earth.………..and there is a good chance you’ve never heard of it.

You might be wondering its name?

It is The Green River Formation.

Heard of it?

I didn’t think so. Because inside those three trillion barrels lies a question and an answer that turns the entire story on its head. Because if no hydrocarbon accumulation on Earth comes close. The question is;

Not just why haven’t you heard of it, but why are we not using it?

Well, there is one problem. In fact, it is more than a problem. It is the answer and the detail upon which the entire promise of the Green River Formation stands or falls.

The extraordinary numbers that make headlines do not describe trillions of barrels of liquid crude, they describe something different. Within the layered shale rock is an organic material known as kerogen, a chemical precursor from which all oil is formed.

For oil to form it needs time, pressure and heat. Most conventional and non-conventional formations we use today are old. Very old. The majority are from the Mesozoic Era (250 million years ago). Some even older.

The Green River Formation is, in geological terms, young. Its organic-rich sediments were laid down during the Eocene, around fifty million years ago, long after the extinction of the dinosaurs.

While nature began the process, it never quite finished it.

The Permian Basin, for example, owes its name to rocks formed before the Mesozoic period, within the Permian Period closer to 300 million years ago. A time when the earth had only one super continent and before the first dinosaurs walked the Earth.

That difference in age is more than a geological curiosity. Time is one of nature’s most important ingredients. Given sufficient burial, heat and millions upon millions of years, organic matter slowly matures into complex hydrocarbons. The Green River Formation simply has not travelled as far enough along that journey. Much of its ancient matter remains trapped in the intermediate form. Nature performed much of the work, but not all of it.

The result is rock impregnated with an organic, waxy material that still requires further heating before it becomes oil. In other words, the Green River Formation does not contain trillions of barrels waiting to be pumped. It contains the ingredients from which trillions of barrels might one day be manufactured.

Conventional oil represents geology at its most generous. By the time humanity arrived, nature had already completed almost all of the work. Drill into the right formation and oil rises towards the surface, driven by pressures accumulated over time.

The Green River Formation offers no such generosity. Humanity must complete the final chapter that geology left unfinished. Here, the hydrocarbons remain imprisoned within the rock itself. Before a single useful barrel can be produced, the stone must first be heated to temperatures of around 500°C before the kerogen begins to decompose into liquid hydrocarbons. In doing so, we are attempting to compress into hours a transformation that nature might perform over an immense period of time. Humanity is, in effect, finishing the work that geology began fifty million years ago. Before a single barrel can emerge, the rock must be mined, moved, crushed and heated. At every stage energy is spent in the hope of recovering still more energy.

So why have I written at length about an oil formation that promised so much but is neither economically or technologically feasible?

Because this article isn’t about the Green River Formation. It’s about the difference between barrels in the ground and usable barrels for civilisation. It’s about the difference between gross energy and net energy. It’s the difference between energy that enhances Modern civilisation and those that don't. And it’s about the immense repercussions for our monetary system….

Our way of life was never been built upon gross quantities of energy. It has always depended upon something far more subtle.

Surplus.

That surplus is what enables complex society to exist. And this is why the Green River Formation matters. It demonstrates that abundance is a far more complicated idea. It has boundaries. And we are pushing them.

It forces us to confront a misunderstanding that reaches far beyond a single geological formation. We have spent decades discussing energy as though the quantity beneath the ground were the only number that mattered. But what really matters is what remains after the work of obtaining them is done.

Three trillion barrels looks very different from that perspective. The numbers have not changed but the usefulness has. A barrel is not simply a barrel. They are separated by the amount of work required to bring them into existence.

And that is why the Green River Formation matters. It has remained largely untouched despite being known for more than a century. Because, throughout the age of cheap conventional oil, civilisation has always opted for the easier barrel. When the earth freely offers high-quality energy elsewhere, there is little economic or energetic incentive to manufacture what geology never fully completed.

The Green River Formation is neither a fraud nor a miracle. The hydrocarbons are there. The geology is real. The numbers are real.

The illusion lies elsewhere.

It lies in believing that the existence of energy is the same thing as the availability of energy.

Those are not the same thing and they never have been. And it is that distinction, more than the astonishing scale of the Green River Formation itself, that may prove to be one of the most important lessons in understanding the future of industrial civilisation.

For two centuries civilisation has been built upon fuels so abundant, concentrated and accessible that almost none of their energy had to be spent obtaining the rest.

The Green River Formation is therefore more than an immense geological curiosity. It is a benchmark against which the future of energy can be measured.

As long as civilisation can afford to ignore the largest hydrocarbon resource ever discovered, we continue to live upon the legacy of higher-quality energy. The day we are forced to depend upon it may not mark the beginning of a new era of abundance. It may silently announce the end of the old one.

A personal note:

For those of you who have made it to the end of this article I wish to explain where we are on this journey. My writings, as some know but most do not, have not been randomly compiled essays across diverse subjects ranging from money, energy, economics, climate, and thermodynamics. You might notice that every article ends with the same line. “This post is part of a series of essays linked to a wider macro thesis: The Long Convergence”. They are non-chronological reworked articles from the book of the same name (being published in early 2027). The substack journey needs therefore to pause while that publishing task takes priority. As a result, you will see less frequent writings while the book regains most of my focus. I thank you for support to date and will be back when the time is right.

TLC

I grew up in a time when television had 4 channels and video games were on tape cassettes that took half an hour to load.

As children we would find other things to amuse ourselves. My brother was fascinated by scissors, with cutting things up. Some things were allowed (paper, card), other things were not (the dining table cloth, my pyjamas).

But for me, it wasn’t cutting things up that caught my interest, it was fire. I was obsessed with it. Not in a pyromaniac way but in a mesmerised awe of what it was. I loved watching the flames and the glowing embers, still hot and hungry for more coals.

Perhaps that is why this question occurs to me then and still does today. Why does coal burn? Why does any fuel burn?

It seems an obvious question. An easy one, perhaps. But could you explain it to my five-year-old self?

The usual answer is, “Because fuels contain energy.” But that merely replaces one question with another.

As a child I discovered very well what would and wouldn’t burn but I never really understood why. Why do they burn? Why do they have energy? And if they have it, where does the energy come from?

The answer?

The answer begins ninety-three million miles away. With our Sun.

We look into the sky and see a bright, warm yellow orb that provides heat and light. But we are all somewhat deceived.

Sound does not travel through the vacuum of space. But Imagine for a moment it could.

In that world, we would never hear the gentle chirp of birdsong at dawn or the rolling waves of the ocean on a warm summer evening.

What we would hear is the sonic texture of a raging nuclear orchestra. A deafening tectonic thrum of superheated plasma. A relentless, tearing hiss of solar winds ripping across the sun’s surface. The sharp booming crackle as magnetic fields stretch snap and detonate in solar flares, heated to millions of degrees. Violent solar eruptions with the energy of a trillion atomic bombs.

The noise would be both physically painful and psychologically terrifying. And yet we hear nothing, not a single sound. Audibly protected by the vacuousness of our surroundings. The sun, forever a silent presence.

But it is not just the noise that we are insulated from. What we experience as heat and light are just filtered remnants from a spectrum of intense radiation. Utterly deadly to the planet were it not for the protective shield of the magnetosphere and the atmosphere.

What makes it through is mainly visible light and some UV. That small share is enough to sustain every ecosystem, drive the weather, warm the oceans and make life itself possible.

But a tiny fraction of this light energy follows a different path.

Below is an equation that most of us encountered at school at some stage and (in all likelihood) forgot. Yet it is not a lesson for children. It is one of the most profound equations in science and represents (as you will see) the conservation of energy principle as laid out in the first law of thermodynamics.

Below is the equation for photosynthesis:

Carbon dioxide and water along with sunlight becomes glucose and oxygen. A relatively simple equation. In reality, it describes one of the greatest acts of energy transformation on Earth.

To understand why, we first need to understand the molecules themselves.

Carbon dioxide and water are stable. Carbon is comfortably bonded to oxygen. Hydrogen is equally content within water. Chemists describe these molecules as occupying a relatively low-energy state. Left alone, they have little reason to become anything else. They are happily bonded to each other.

And with nothing to disrupt them, that is the way these molecules existed for billions of years. However, 2.4 billion years ago, microscopic organisms called Cyanobacteria developed the ability to obtain biological energy via the process of photosynthesis. Using nothing but sunlight, microscopic bacteria developed the ability to tear carbon from oxygen, split water into its constituent atoms, and rebuild them into sugars, and organic compounds. The waste product was oxygen.

Vast blooms of these bacteria over millennia, led to the great oxygenation of the earth. The air we breathe is made possible from that event.

Until photosynthesis evolved, the Earth received sunlight exactly as it does today. The difference was that almost none of it stayed. It arrived, warmed the planet for a moment and radiated back into space. Photosynthesis changed that. For the first time in Earth’s history, a tiny fraction of the Sun’s energy was captured, stored and carried forward. Life became the planet’s way of saving sunlight.

Plants do not simply absorb sunlight. They convert it and store it. The energy arriving as electromagnetic radiation from the Sun is stored within the molecular bonds of matter itself. Sunlight is transformed into molecules that contain more chemical potential than the carbon dioxide and water from which they were built.

This is the tension created by photosynthesis. Carbon and Hydrogen seek to return to their lower energy state, sunlight fuelled their uncoupling.

Every microscopic algae, every plant’s leaf is therefore a tiny energy factory, turning sunlight into matter.

So, I return to the original question that my 5 year old mind asked when throwing his lolly stick on the fire. Why do fuels have energy? Why do they burn?

The answer? They have energy because sunlight has already performed the work of building them. The energy contained within a fuel is the memory of work already done.

In the case of our civilisation’s energy base, for hundreds of millions of years this process repeated itself on a scale we cannot begin to grasp. Forests spread across ancient continents. Vast blooms of microscopic algae drifted through prehistoric oceans, blooming and dying, over and over with the seasons. Sunlight was quietly being harvested and locked inside living matter.

Most of that stored energy soon returned to nature. Plants died and decomposed. Animals fed upon them. Microorganisms consumed what remained. The cycle continued, unending, for eons.

But a tiny fraction were buried beneath sediments, sealed from oxygen and compressed by heat and pressure over time, some of that ancient organic matter slowly transformed into coal, oil and natural gas.

Complex hydrocarbons are therefore far more than fossil fuels. That name does them a disservice. They are ancient sunlight preserved in molecular form. Every barrel of oil is the energy from solar organisms that lived and died again and again in a past world. Every seam of coal is a million compressed summers. Every reservoir of natural gas is sunlight that fell upon this planet long before the first hint of mankind.

But more than that. Photosynthesis is a beautiful illustration of the first law of thermodynamics. That energy can neither be created nor destroyed, merely changed. The conservation of energy.

While photosynthesis slowly stores energy, combustion undoes it, releasing in a few moments the energy that sunlight invested a long time ago.

There is a beautiful symmetry to it. The equation of burning a hydrocarbon:

Look carefully at the products from burning. They are the very same molecules from which photosynthesis began:

Carbon dioxide (CO₂) and water (H₂O).

The only thing that changed was time. In the first equation, the sun’s energy was gathered slowly over millions of years. In undoing it, through combustion, those millions of years are reduced to a few moments. Burning fossil fuels is photosynthesis in reverse, undoing work that previously took place over eons.

So why do they burn? That goes back to the happy relationship that carbon and hydrogen once had with oxygen before the plants split them apart.

The hydrocarbons created by ancient life exist in a higher-energy arrangement than carbon dioxide and water. A spark, a flame or the compression inside an engine provides the small amount of activation energy needed to begin the reaction. Oxygen rapidly combines once more with carbon and hydrogen, returning those atoms to the lower-energy arrangement they naturally prefer before solar powered plant life forced them away from each other. As those new chemical bonds form, the energy originally supplied by sunlight is released.

The spark is just the catalyst, the flame is sustained by the work that sunlight performed long ago.

Each newly formed bond releases enough energy to break neighbouring bonds, producing the cascading chain reaction we recognise as a flame.

There is a remarkable elegance to this cycle.

Photosynthesis used sunlight to separate carbon from oxygen and build energy-rich molecules. Combustion allows those same atoms to return to their more stable arrangement.

Nature stores while fire returns.

What took millions of years to accumulate can be released in moments. When oil, gas or coal burns, geological time collapses into an instant.

Modern civilisation burns a hundred million barrels of oil every day. Every one of those barrels represents sunlight that first reached the Earth millions of years ago, patiently collected by living organisms, transformed by geology and finally released by humanity.

Seen in this light, hydrocarbons cease to be commodities traded on financial markets. They become an inheritance gifted down by the earth as wealth from the only thing that made life possible, the sun. A way to shortcut the restrictions imposed by the first law of thermodynamics.

For two centuries we have lived not simply on energy, but on an immense reserve of stored solar work. The Industrial Revolution was, in many respects, humanity in the early stages of discovering how to spend an energy inheritance.

This changes how we should think about civilisation itself.

Technology, economics, engineering, politics. Each has shaped the modern world. Yet beneath everything lies something far older.

Ancient energy, radiated across the silent void of space. Captured, stored and surrendered to time.

Photosynthesis built the modern world twice. First, by filling Earth’s atmosphere with the oxygen that made complex life possible. Second, by storing vast reserves of solar energy inside organic matter that would eventually become the coal, oil and natural gas upon which industrial civilisation was built.

Even to this day around 86% of our energy demands are met by this ancient source (biomass, coal, oil and natural gas). The burning of solar energy stored in matter.

We have become so accustomed to combustion that we don’t stop to consider what it really is or why it happens. Few of us recognise the extraordinary chemistry that makes it possible.

We don’t burn oil. We release the energy of ancient sunlight.

That is why fuel has energy. Because it is sunlight that refused to disappear. Captured by leaves, concentrated by life, preserved by geology.

We do not merely burn fuel. We spend an ancient solar inheritance.

What happens afterwards might be the Burning Question of our age.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

History has many maps.

But not for this.

Sailors once marked the limits of the known world with dragons, kraken and all manner of sea monsters. For those who ventured beyond familiar waters, the unknown inspired genuine fear.

From our modern perspective it is easy to dismiss such beliefs as superstition. Yet the monsters were never really the point. They marked the boundary beyond which experience could no longer guide them. Past that line, no chart could say what lay ahead. The danger was not that monsters existed. It was that no one knew what did.

We stand in a similar position today. The edge of our map is no longer the edge of the Earth, but the edge of historical precedent. Beyond it lies a globally integrated fiat monetary system that humanity has never navigated before.

Whether monsters lie ahead is not the question. What matters is that no one has sailed these waters before. Beyond this point, the charts simply end.

What if the defining feature of our age is that, for the first time in history, every major economy is operating under the same monetary architecture, deeply interconnected through a single unproven global monetary system?

History can only guide us where history has already been. Beyond that lies something altogether different….

Uncharted waters.

The Comfort of Precedent

Every generation believes its challenges are unique, yet most eventually discover that history has visited something remarkably similar before. Financial panics, banking crises, sovereign defaults and monetary failures are hardly rare events. They recur throughout history.

This habit of looking backwards has served us well. If we can identify the historical parallel, we can infer the likely outcome.

Recency also play an important part. We are inclined to treat the world we have personally experienced as normal.

Recency bias: a cognitive error where our brains overvalue more recent events and information simply because they are fresh in our memory. This distorts judgment, leading us to incorrectly assume the immediate past perfectly dictates future trends.

For most living policymakers, investors and economists, the normal world is one that supports that bias. It is one of fiat currencies, expanding credit, expanding energy, activist central banks, liquid capital markets and governments able to refinance rather than repay their debts. That world feels permanent because it has lasted long enough to become familiar.

There is no central banker, economist or politician serving today that has experienced during their careers, a currency system other than the one we have today.

This creates an unspoken risk.

It may simply be that we have lived our entire professional lives inside one unusually favourable phase of a young monetary experiment.

Our history becomes a map. And maps are reassuring because they suggest that however unfamiliar today’s landscape appears, someone has travelled this road before. The difficulty arises when the road itself has never previously existed. Because every historical comparison contains an implicit assumption that today’s system resembles yesterday’s.

Increasingly, that assumption deserves to be questioned.

Every historical comparison depends on two things remaining broadly the same. The first is human behaviour. Fear, greed, speculation and political incentives have changed little over the centuries. The second is the system within which those behaviours play out.

The first assumption is likely valid. Human nature is a constant. We will behave the same way humans have in whatever circumstances present themseves. But it is the second assumption, the system within which those behaviours play out, that deserves closer examination.

When economists compare today’s debt with post-war America, or today’s inflation with Weimar Germany, or today’s asset bubbles with Japan in the late 1980s, they are doing something reasonable. They are searching for patterns. History is, after all, our greatest laboratory. We cannot run experiments on civilisations, so we study the experiments that time has already conducted.

But every experiment has conditions. Change the conditions sufficiently, and the comparison begins to lose its explanatory power.

Rome was not a global financial system. Weimar Germany was not the issuer of the world’s reserve currency. Argentina could default because the rest of the world continued functioning. Britain could decline and lose reserve currency status because another power was ready to assume its place.

Even the Great Depression unfolded within a monetary architecture fundamentally different from today’s.

Each historical crisis occurred within a world that still possessed alternatives. Capital could migrate. Trade could reorganise. Another currency, another empire or another monetary framework existed beyond the immediate crisis.

There was always an outside. That distinction is crucial because for the first time in recorded history, the world’s major economies are no longer operating under competing monetary systems. They are operating within variations of the same one.

The dollar, the euro, the yen, the pound and nearly every other major reserve currency differ in governance, politics and geography. Yet beneath those differences lies the same underlying architecture: floating fiat currencies, debt-based money creation, central banking, integrated capital markets and a financial system held together ultimately by confidence.

That convergence is historically extraordinary. It means we are no longer comparing one monetary experiment with another. We are participants in a single global monetary experiment.

And that changes the value of every historical analogy that came before.

The map has not simply become incomplete……….It has begun to run out.

Looking back, what is striking is not how old our monetary system is, but how young it is.

The “global financial system” is little more than fifty years old. Before 1971, the world’s monetary architecture was fundamentally different. Before the 1980s, floating fiat currencies remained an experiment. Before the 2000s, global capital markets were far less integrated than they are today. Before 2008, quantitative easing existed largely in academic discussion. The system we now regard as normal is historically recent.

Youth, by itself, is not a weakness. Every institution is new once. The question is whether history has had sufficient time to test it.

The answer, surprisingly, is no.

For most of recorded history, monetary systems were anchored and restrained by something external. Gold and silver imposed physical limits on the creation of money. Even under the Bretton Woods system established after the Second World War, the U.S. dollar remained convertible into gold, at least for foreign governments. Credit could expand, but only within a framework that ultimately rested on a tangible anchor.

That changed in August 1971.

When President Nixon suspended the dollar’s convertibility into gold, the final link between the world’s reserve currency and a physical monetary anchor was severed. At the time it was presented as a temporary measure. In practice, it marked the beginning of an entirely new monetary era.

For the first time, the global economy began its transition towards a system in which money derived its value from confidence alone. From faith in the system.

Fiat money is not inherently destined to fail because it lacks gold. Modern economies require monetary flexibility that a rigid gold standard struggles to provide. The point is not that fiat currencies cannot function. Clearly they can, and for decades they have.

The point is that the system we now inhabit has remarkably little historical precedent. More importantly, it has never existed on a genuinely global scale.

Previous monetary failures occurred within a world of alternatives. When one nation debased its currency, investors could move elsewhere. When an empire declined, another was rising. When one banking system failed, capital could migrate into another governed by different rules and backed by different institutions.

There was always another harbour.

Today, that assumption no longer holds.

The dollar, the euro, the yen, the pound and virtually every other major reserve currency differ politically, geographically and institutionally. Yet beneath those differences they share the same essential architecture. They are fiat currencies, created through credit, managed by central banks and sustained ultimately by confidence in the financial system that surrounds them.

We refer to competing economies but they are competing currencies within the same monetary system.

This is an important distinction.

It means that for the first time in history, the world’s major economies are not conducting separate monetary experiments. They are participating in one shared experiment together.

If there were no signs of the system beginning to crack, this observation would carry less weight. But when viewed alongside the accumulation of sovereign debt, the reality of our predicament comes into focus.

These signs are not yet the hallmarks of outright monetary collapse, but they are consistent with the early stages of monetary strain. Across much of the developed world, sovereign debt has continued to rise faster than economic output, while central bank balance sheets remain historically elevated following successive interventions.

Inflation, once regarded as largely conquered, has re-emerged as a structural concern, eroding purchasing power and exposing the limits of debt-financed growth. At the same time, central banks have been accumulating gold at the fastest pace in decades, while an increasing share of international trade is being settled outside the traditional reserve currency framework.

None of these developments proves that the present system is approaching its end. Taken individually, each can be explained. Taken together, however, they suggest that confidence in the existing monetary architecture is no longer as unquestioned as it once appeared.

History suggests that when confidence in a monetary system begins to weaken, the sequence is often familiar. Governments become increasingly reliant on debt and monetary expansion to sustain obligations that economic growth alone can no longer support. Purchasing power gradually erodes, capital seeks refuge in harder assets or more trusted jurisdictions, and policymakers respond with progressively greater intervention to preserve financial stability.

Whether the current system ultimately follows that historical path remains uncertain. What makes our situation unique is not the possibility of monetary strain itself, but that it would unfold within a global fiat system for which there is no historical precedent.

And while history contains many examples of individual governments becoming over leveraged. It contains remarkably few examples of almost every major developed economy increasing leverage simultaneously under the same monetary architecture.

This is where historical analogy begins to lose its footing.

If this were simply an American story, history would offer countless comparisons. The United States would merely join a long list of heavily indebted powers. Britain has been there. France has been there. Spain has been there.

History knows how to tell those stories. But the question becomes much harder when the same pattern begins appearing everywhere at once.

The chart below steps back from the United States and looks instead at the world’s major developed economies as a whole. Different governments. Different political systems. Different cultures. Different demographics.

Collectively they reach same outcome. Ever growing debt.

No two nations are identical. Japan’s debt is extraordinary. Germany remains comparatively restrained. The United States has the highest debt in nominal terms but also enjoys the unique privilege of issuing the world’s reserve currency.

The differences matter. But so does the broader pattern. What began as separate fiscal stories has gradually become one collective trajectory.

This is no longer a question of whether one government borrowed too much. It is whether an entire monetary architecture has become structurally dependent upon ever-expanding debt.

That is a profoundly different question.

And history offers no prior examples with which to answer it.

The Lifeboat Question

Every monetary crisis in history has contained one key feature.

An exit.

Capital doesn’t wait patiently for a currency to fail. It moves. Initially it happens gradually, sometimes in panic, but it moves nonetheless, (or at least tries to). Investors exchange one asset for another. Depositors withdraw funds. Wealth migrates towards jurisdictions perceived to be more stable. Hard assets and precious metals are swapped for devaluing currency. History is filled with examples of money fleeing uncertainty in search of greater confidence elsewhere.

Every crisis contained a lifeboat.

The assumption underpinning all of these episodes was that somewhere beyond the immediate crisis existed another monetary system governed by different rules, stronger institutions or greater confidence.

Today, that assumption deserves closer scrutiny.

Where exactly is the lifeboat?

Not which asset might outperform over the next five years, or which stock pick or sector, or which country appears fiscally stronger than its neighbours. Where does capital ultimately seek refuge if confidence in the architecture itself begins to weaken?

The dollar remains the world’s reserve currency. The euro, the yen, the yuan represent alternative currencies, but not alternative monetary systems. They share the same fundamental characteristics: fiat money, central banking, debt-based credit creation and floating exchange rates. They compete with one another, yet all operate within the same broad framework.

Gold occupies a different position. It remains a monetary asset rather than a fiat currency, and central banks have quietly become persistent buyers once again. Yet gold is not a monetary system. It cannot finance global trade, settle wages, provide commercial credit or operate the payments infrastructure upon which modern economies depend.

It is a refuge. Not a replacement. A lifeboat with not enough seats for everyone.

History teaches us what happens when individual currencies fail. It teaches us remarkably little about what happens when confidence is tested across a globally integrated monetary architecture built upon the same underlying principles.

Perhaps the system proves more resilient than I expect and we continue another 50 years. Perhaps it evolves into something entirely different.

Or perhaps history’s silence is itself the most important observation.

Because beyond this point, precedent begins to give way to speculation. Speculation that the realisation of the fragility and unprecedented impact of a global monetary crisis is known.

And if that is true then a new monetary system is not only likely but inevitable.

If history offers no map, then the future will likely not resemble the past. The next monetary system is unlikely simply to be another version of the last. It will reflect the constraints, technologies and political realities of the world that creates it.

Whether that future brings greater freedom or greater control is a question for another essay.

For now, this is where the map ends.

The voyage goes on.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

For more than half a century, the liabilities of the United States government have expanded persistently faster than the income available to support them.

Irrespective of which party occupied the White House, regardless of recessions, wars, financial crises or economic booms, one trend has remained consistent. The federal debt kept growing. Sometimes quickly. Sometimes extraordinarily quickly. But always upward.

That trend suggests something more fundamental is at work than politics. But more importantly…

How do we know when that burden becomes too large?

One Ratio to Rule Them All

The most dangerous assumptions are usually the ones we don’t stop to question. Within modern economics, the most dangerous is also the most familiar.

Debt to GDP.

For more than half a century, debt-to-GDP has become one of the defining ratios in modern economics. It is the most widely quoted metric and has become so repetitively familiar it’s almost inaudible.

But familiarity is not the same as correctness. Debt is a liability on a balance sheet. GDP is a measure of economic activity over the course of a year.

They are not the same kind of thing.

That distinction may sound arbitrary, but it has profound implications. Every lender in the world understands that a borrower’s financial strength is judged against the direct income available to support its obligations. Banks do not issue mortgages based on the economic output of the street you live on.

They ask a much simpler question. How much income does the borrower actually generate?

Governments are different in many respects, but not in this one. They may legislate, tax and issue currency, but they do not repay debt with GDP. They repay it from one recurring source of income.

Tax receipts.

And if governments repay debt with tax revenue rather than GDP, then another question immediately follows.

Have we been measuring sovereign leverage against the wrong denominator all along?

GDP measures economic activity, not government income. It records the value of goods and services produced across an economy, regardless of whether that activity expands productive capacity, repairs previous losses or merely redistributes wealth. Borrowing to build productive infrastructure and borrowing to repair storm damage both increase GDP. Yet neither tells us how much income ultimately flows to the Treasury.

Governments cannot spend GDP. They spend tax receipts, and tax receipts remain the only recurring source of income available to service public debt.

Which brings us back to the original question. It is a question that sounds obvious only after it has been asked. If governments repay debt from tax revenue rather than GDP, why has debt-to-GDP become the dominant measure of fiscal sustainability?

It compares public liabilities with the scale of an economy. That is useful to know. But if the question is not economic size but financial leverage, then usefulness and appropriateness are not equivalents.

Every borrower, whether household, company or state, ultimately faces the same question. Has the ability to generate income kept pace with the liabilities that have been accumulated?

Instead, we continue to compare a balance-sheet liability with a measure of annual economic output of the country and treat the result as though it tells us everything we need to know about fiscal sustainability. It does not.

But this isn’t a philosophical question. It’s one we can test.

Viewed through the lens of tax receipts rather than GDP, the financial history of the United States looks very different. The story is no longer one of debt alone, but of leverage.

And if leverage is the relationship between liabilities and income, then our fiscal history becomes less a story of debt and more a story of two lines slowly drifting apart.

Exhibit A: Two Lines

Let us ignore ratios and percentages entirely.

The chart below shows the gross federal debt by year alongside the gross federal tax receipts. Look at the two lines. One represents the federal government’s income. The other represents its liabilities.

What matters is not simply that both have risen. What matters is that they have not risen together.

The green line represents the federal government’s annual income through tax receipts. It has grown enormously over the past half century, reflecting a larger economy, a growing population and decades of inflation. The government today collects around $5 trillion each year compared with less than $200 billion in 1970.

The red line tells a different story. Federal debt has not simply grown alongside government income. It has accelerated away from it. What began as a relatively modest gap has become an ever-widening gulf, with debt at $38 trillion in 2025 while annual tax receipts remain a fraction of that figure. By the end of 2026 that figure will reach $40 trillion.

This is the first sign that something important has changed. The issue is not that debt has increased. We can expect that from a growing economy. The issue is that debt has consistently grown faster than the government’s own income. Before calculating a single ratio, the balance sheet already looks fundamentally different from the one America had half a century ago.

Exhibit B: The Leverage

Once we have seen the two lines diverge, we can combine them into a single measure.

This chart asks a simple question that every lender asks of every borrower: how large are the liabilities compared with the borrower’s income? In simple terms, what is your income versus your debt. The question every mortgage provider in the world asks.

In 1970, the answer was straightforward. The federal government owed less than two years of annual tax receipts. By the early 1990s that figure had climbed above three years. A brief improvement followed during the budget surpluses of the late 1990s, but the long-term direction soon reasserted itself. Successive recessions, financial crises and fiscal interventions pushed the ratio steadily higher until today, when federal debt stands at around seven and a half times annual tax receipts.

This should not be interpreted as a repayment timetable. Governments cannot devote all tax revenue to debt reduction because they must continue to fund every other function of the state. Rather, the ratio is a measure of leverage. It tells us whether liabilities are growing faster than the income available to support them.

The trend is unmistakable. Over more than fifty years, the federal balance sheet has become progressively more leveraged against its own income.

Exhibit C: The Divergence

Perhaps the clearest way to understand the story is to forget dollars entirely. This chart resets both debt and tax receipts to the same starting point in 1970. From there, it simply measures how quickly each has grown.

The result is striking.

Federal tax receipts have increased by roughly twenty-six times since 1970. Yet over the same period, federal debt has increased by around one hundred times.

This chart reveals the underlying dynamic driving every other measure in this article. The problem is not that government income failed to grow. It grew substantially. The problem is that liabilities grew almost four times faster.

This matters because leverage is created not by just by debt, but by the relationship between debt and income. When liabilities consistently outpace the resources available to support them, the balance sheet becomes progressively more dependent upon favourable conditions to remain stable.

This is the arithmetic of leverage.

Exhibit D: The Road Ahead

Historical data tells us where we have been but it cannot tell us exactly where we are headed. The chart below shows the projected debt and revenue of the federal government based on non partisan forecasts.

The projection shown here should therefore be understood as an illustration rather than a prediction but nothing in the chart suggests it is unlikely based on the past trend.

It simply asks what the balance sheet might look like if the broad relationship observed over the past several decades continues, with debt growing faster than government income.

If that occurs, the gap between the two lines continues to widen. Debt approaches levels that become increasingly detached from the government’s own revenue base, while leverage continues its long upward march.

The important point is not the precise numbers in 2035. Those will undoubtedly prove wrong in one direction or another. The important point is the direction of travel. If liabilities continue to compound faster than income, leverage continues to increase. That is true regardless of whether debt reaches $80 trillion, $90 trillion or some entirely different figure.

If federal debt were to reach around $86 trillion by 2035, an average financing cost of 4% would imply annual interest expense of approximately $3.4 trillion. That would consume more than one-third of the Congressional Budget Office’s projected federal tax receipts for that year, before a single dollar was spent on defence, healthcare, Social Security or any other function of government.

What This All Means

For more than half a century the liabilities of the federal government have expanded persistently faster than the income available to support them.

That is not an opinion. It is an observation. And observations have a habit of becoming more important when they persist for fifty consecutive years.

At a certain point, leverage begins to change the character of the problem. Rising interest costs no longer merely reflect higher debt, they begin to accelerate it. More borrowing leads to larger interest payments. Larger interest payments require more borrowing. The debt ceases simply to grow. It begins to compound upon itself.

But If the federal balance sheet has become progressively more leveraged for over half a century, why has the system not already broken?

It is a fair question. Indeed, it is the question that has led many economists to dismiss concerns about public debt altogether. Because if it hasn’t happened yet, perhaps it never will. If leverage has been rising since the 1970s, and the United States has nevertheless become wealthier, more technologically advanced and more financially powerful, perhaps the debt simply does not matter.

But the arithmetic never disappeared, but rather, it has been accommodated.

One of the great oddities surrounding sovereign debt is that governments never really repay what they borrow. In reality, very little government debt is ever extinguished. Treasury bonds mature, but rather than being paid off from accumulated savings, they are generally replaced with new bonds. Yesterday’s debt is refinanced with tomorrow’s debt. The balance sheet rolls forward.

The system functions not because debt is repaid, but because confidence allows it to be continually renewed. That distinction is crucial.

A homeowner who never pays off a mortgage but continually refinances it can do so indefinitely as long as income grows, lenders remain confident and credit remains available. The debt has not disappeared. It has simply been carried forward into the future.

Modern sovereign finance operates in much the same way.

For the United States, several extraordinary advantages have made this possible. The dollar became the world’s reserve currency after the Second World War. U.S. Treasury securities evolved into the foundation of the global financial system, held by central banks, pension funds, insurers and financial institutions around the world. Demand for government debt therefore extended far beyond domestic savers.

At the same time, the modern era was characterised by almost uninterrupted economic expansion, abundant fossil energy, globalisation, favourable demographics and, after the early 1980s, a four-decade decline in interest rates. Each of these forces reinforced the others. Economic growth supported higher tax receipts. Falling interest rates reduced borrowing costs. Rising asset prices created additional collateral throughout the financial system. Confidence strengthened precisely because the system appeared to work.

This period now looks less like a permanent feature of capitalism than a remarkably favourable chapter in financial history.

There is an assumption deep rooted within our political and financial system that tomorrow will always be larger than today, that debts of the present can be managed by a future that offers more.

The obsession, politically, with growth, of reaching ‘escape velocity’ is pervasive because it has to be true. If it isn’t, we’ve bankrupted the future to serve the present.

But this belief, that the future will always be bigger, encouraged a reckless form of political behaviour.

If every recession could be deferred or softened with fiscal stimulus, why not just borrow? If every financial panic could be stabilised with central bank intervention, why not just borrow more? If every crisis justified extraordinary spending, and every expansion made the debt appear manageable once again, why exercise restraint at all?

Borrowing gradually ceased to be an emergency measure. It became the default response. The incentives built into the system increasingly rewarded spending today while postponing the costs until tomorrow.

The consequence of growing debt has not been an immediate crisis. Each cycle ended with a slightly larger federal balance sheet than the one before it. Each recovery began from a higher level of debt. Each intervention established a new baseline from which the next intervention would begin.

Viewed year by year, the changes appeared modest. Viewed across half a century, they reveal something altogether different.

The Dependency Trap

The federal government did not just accumulate debt. It accumulated dependence on continued growth. Dependence on low interest rates. Dependence on liquid bond markets. Dependence on the reserve currency status of the dollar. Above all, dependence on confidence.

That is the hidden implication of rising leverage. A highly leveraged balance sheet does not necessarily fail but it becomes less resilient.

It loses the capacity to absorb shocks that once would have been manageable. A slowdown that might previously have been inconvenient becomes fiscally significant. A rise in borrowing costs that once would have been absorbed begins to alter budget priorities. The system becomes increasingly sensitive because it has less room for error.

Financial resilience is ultimately the existence of slack. It is the margin that allows a borrower to absorb unexpected shocks without fundamentally altering its behaviour. As leverage rises, that margin steadily disappears. Every recession requires more borrowing than the last. Every crisis leaves the balance sheet worse than before. The issue is not simply that debt increases. It is that the room for error steadily declines.

A highly leveraged balance sheet is not necessarily unstable. But it is increasingly sensitive. The entire system becomes progressively dependent upon the continuation of unusually favourable circumstances.

Where do we go from here?

The purpose of this article has not been to predict imminent currency collapse. It has firstly to ask whether we have been measuring the financial position of governments correctly.

What this leads to, I would say, is the realisation that the true leverage of the modern sovereign state looks very different from the one implied by quoting debt-to-GDP percentages.

Choosing a denominator is never neutral. It determines how we see the world. Measured against GDP, the United States appears heavily indebted. Measured against tax receipts, it appears highly leveraged.

Those are related ideas. They are not the same idea.

Before we ask where the route leads to, we should first ask whether we’ve been reading the map correctly. Because if the denominator has been wrong all along, then so too may have been our understanding of the journey.

Which leaves one obvious conclusion.

In the next article I will go further into this subject to consider the outcome of this compounding issue. For now I shall leave you with one thought.

For centuries, governments have failed one by one. Empires have defaulted. Currencies have collapsed. Debt crises have come and gone. But never before has every major economy, every country sailed under the same faith based monetary system all at the same time.

History has many maps. But not for this.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

From thousands of feet up, southern Spain looks mostly as you might expect. Rugged mountains. Dusty earth fading into the blue of the Mediterranean.

But look a little closer (or further away perhaps) and you’ll discover something most people miss. It happens to be the largest artificial structure on earth, entirely visible from space.

Stretching across the southern coast of Spain is a vast white expanse covering 150 square miles. Against the dark browns and ochres of Andalusia’s dry landscape, it appears unnatural, as though winter has settled permanently along the sunny Mediterranean coast.

But it’s not snow. Nor is it a white sandy beach or vast salt flats.

It’s a sea of white plastic. More than 40,000 hectares of it. Some call it the White Sea, the Spaniards call it Mar de Plástico (the Plastic Sea).

Covering an area three times the size of Paris, five times the size of Manhattan, the greenhouse complex around Almería is the largest agricultural installation on Earth. Beneath its polyethylene plastic roofs, millions of out-of-season tomatoes, peppers, cucumbers, courgettes and aubergines are grown every year before beginning their journey to supermarkets across Europe. Around 50% of Europe’s total demand for fresh fruits and vegetables is produced from under these roofs.

To most consumers, these vegetables are entirely ordinary. They sit stocked beneath fluorescent lights in thousands of supermarkets all across Western Europe. They are picked up and dropped into shopping baskets alongside milk, bread and eggs. They are cheap. Familiar. Utterly unremarkable.

So why am I writing about them?

Because they are far from ordinary. Hidden inside every one of those vegetables is a story most of us never see. A story about ancient energy.

We might think about food as just a product of nature. Sunlight falls on the land. Rain waters the soil. Seeds grow into plants. Farmers harvest the result. For most of our history that was broadly true. But today it is barely part true.

Modern agriculture still depends on sunlight, soil and water, but it also depends on an industrial system so vast it has become almost invisible. We see the vegetables. We do not see the machinery that made them possible.

The greenhouses themselves are manufactured from oil-derived plastics. Water is pumped through extensive irrigation networks. Machinery consumes fuel. Packaging requires energy. Refrigerated transport carries produce across borders and distribution centres before it finally arrives at supermarkets where further energy is used to preserve freshness.

Yet perhaps the most important ingredient never appears on the label.

Natural gas.

Most people assume the story of a tomato begins with a seed. In the modern world, it begins somewhere else entirely. It begins in a gas field.

Because every plant requires nitrogen. Without it, growth is impossible. Leaves yellow. Stems weaken. Yields collapse.

For thousands of years, agriculture was constrained by nature’s ability to provide that nitrogen. Farmers relied on manure, compost, crop rotation and whatever fertility could be coaxed from the soil itself. The amount of food humanity could produce was ultimately limited by these natural cycles.

Then, in the early twentieth century, everything changed.

German chemists Fritz Haber and Carl Bosch developed a process capable of pulling nitrogen from the atmosphere and transforming it into ammonia (𝑁𝐻3) on an industrial scale. The process (the Haber Bosch Process) was an extraordinary breakthrough. For the first time in history, humanity could manufacture fertiliser almost without limit.

There was only one catch. The process required enormous quantities of energy. Today that energy largely comes from natural gas.

The consequences transformed civilisation. Crop yields surged. People had access to abundant food. Populations expanded. Cities grew. Modern industrial agriculture became possible. People had access to abundant cheap food. Populations expanded further. Cities grew even larger. And this is where we find ourselves today.

In fact, many scientists estimate that roughly half the nitrogen found in human bodies today originates from the Haber-Bosch process. In a very real sense, natural gas feeds billions of people.

This is the hidden story of the vegetables beneath the white sea of Almería. Long before a tomato begins ripening on the vine, fossil energy has already entered the process.

Natural gas becomes fertiliser. Fertiliser becomes plant growth. Plant growth becomes food. The tomato is simply the form that energy happens to take.

But there is a deeper meaning hidden beneath the plastic roofs of Almería. The vegetables growing there depend on sunlight. But not today’s sunlight. They depend on sunlight that fell upon the Earth millions of years ago.

The natural gas used to manufacture fertiliser is itself ancient solar energy. In the distant past, prehistoric plants captured sunlight through photosynthesis. Over immense stretches of geological time this process of organic life cycle continued again and again. Nutrients in the soil combined with solar energy. Within specific regions and in special conditions, through a miracle of geology, some of that stored energy became the oil, gas and coal that has powered civilisation for the past two hundred years.

Seen this way, the greenhouse complex of southern Spain resembles less a farm than a vast energy-processing system. The crops are merely the visible output. The true inputs are harder to see. Natural gas. Oil. Electricity. Infrastructure. Transport. Chemistry.

The satellite image reveals something that is usually hidden from view. What appears on a supermarket shelf as a simple vegetable is actually the endpoint of an enormous industrial process.

A pepper is not just a pepper. A tomato is not just a tomato. Each represents the successful coordination of extraction industries, chemical plants, manufacturing facilities, transport networks and agricultural systems spread across entire continents.

This is not a criticism. It is an observation.

Modern agriculture is one of humanity’s greatest achievements. The white inland sea around Almería helps feed millions of people. It allows fresh produce to be available throughout the year. It has dramatically expanded choice, convenience and abundance.

But every achievement has foundations. The foundation of this one is energy. That reality becomes difficult to ignore once viewed from above. The white sea resembles an industrial city more than traditional farmland. Its scale is staggering. Its complexity extraordinary.

And it raises an uncomfortable question. How many people understand what they are actually looking at when they walk through a supermarket?

We see vegetables. We do not see fertiliser plants.

We see convenience. We do not see gas fields.

We see abundance. We do not see the energy systems that sustain it.

Perhaps that is the defining characteristic of modern civilisation. Not that it consumes vast quantities of energy, but that it has become so successful at hiding the process from view.

The supermarket shelf is the final act of a much longer drama. By the time we arrive, almost all of the important work has already been done. The vegetables sit there silently, stripped of their history.

The satellite image restores it. For a moment, the hidden architecture of everyday life becomes visible. The white sea of Spain is often described as one of Europe’s most important agricultural regions.

It is that.

But it is something else as well. It is a monument to the age of energy abundance. A place where natural gas becomes fertiliser, fertiliser becomes vegetables, and vegetables become the illusion that abundance arrives effortlessly.

The next time you pick up a tomato in the middle of winter, consider the journey that brought it there. Consider the plastic stretching across the Spanish coast. Consider the fertiliser, the pipelines, the trucks and the warehouses.

Then consider something stranger still.

Perhaps that is the real story hidden beneath the White Sea of Spain.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

Douglas Adams, the late British comic novelist, wrote The Hitchhiker’s Guide to the Galaxy, one of the great cult classics of modern science fiction.

Published in 1979, in a time before AI had been conceived, in Adams’ universe, the most powerful computer ever built is tasked with answering the Ultimate Question of Life, the Universe and Everything. The machine, known as Deep Thought, is so vast and sophisticated that it spends seven and a half million years calculating the answer.

Finally, after millions of years of computation, Deep Thought delivers its verdict.

The answer to the Ultimate Question of Life, the Universe and Everything, is:

42

For decades the number has wandered through popular culture as a piece of absurdist humour. It appears on websites, T-shirts and internet forums. It is simultaneously absurd and profound.

Recently, however, I found myself staring at the same number for an entirely different reason.

Global recoverable oil reserves are estimated at 1.6 trillion barrels. The world consumes 38 billion barrels each year. Divide one by the other.

The answer is 42.

42 years.

There is something unsettling about that arithmetic. Human civilisation has spent the last two centuries constructing the most complex society in history centred around a finite fuel. And when we perform the simplest of calculations, the answer turns out to be 42.

The difference is that this time the question is obvious. What happens when the fuel that built our industrial civilisation begins approaching its limits?

The arithmetic is simple. But the implications are not. And the answer this time round isn’t a joke.

Over 85% of global energy consumption is non renewable primary energy comprising oil, gas, coal and biomass. Despite decades of investment in wind, solar, hydro they remain a small proportion of global energy mix. The chart below is a powerful representation of this reality.

The first thing to understand is that the forty-two year figure is both technically correct (within a margin of error) and fundamentally misleading. There are 1.6 trillion barrels remaining. Consumption is approximately 38 billion barrels per year. Therefore we have around four decades of supply.

The calculation is arithmetically sound but the conclusion is not. Civilisation does not run on reserves. It runs on flows. A barrel sitting underground does not power anything. What matters is not how much oil exists in total, but how much can be produced every day, every month and every year at a cost the economy can tolerate.

Oil does not disappear suddenly when reserves are exhausted. Production reaches a plateau, begins to struggle and eventually declines. Long before the final barrel is extracted, the economic consequences of lower flows begin making themselves felt.

The distinction matters enormously because modern civilisation was not built on oil reserves. It was built on oil abundance. Not on squeezing the last reserves from a depleted field.

The giant conventional oil fields that powered the twentieth century delivered extraordinary quantities of energy at remarkably low cost. They were the equivalent of discovering vast underground armies of invisible labourers (see Kings of the Oil Age). What mattered was not merely the existence of oil. What mattered was the flow.

The flow created growth. It created prosperity. The flow created the modern world.

This is why the question is not whether oil exists in the ground. The question is whether the flows required to sustain industrial civilisation can continue and for how long. The answer becomes even more uncomfortable when we consider how thoroughly modern institutions depend upon growth.

Governments, pension systems, property markets, financial markets, our debt based monetary system, all require growth. Not as a preference, but as an essential component. Growth within our economic model is not optional, it is mandatory.

The entire architecture of modern civilisation rests upon the expectation that tomorrow’s economy will be larger than today’s. This assumption is utterly embedded. Growth is not simply something modern civilisation desires. It is something modern civilisation requires.

This is where the arithmetic of finite fuel begins colliding with the assumptions of infinite growth.

Consider financial markets. At the time of writing, many of the world’s largest technology companies trade at valuations that imply decades of future expansion. The trailing PE ratio of the Nasdaq is 35 times earning. This is based on an expectation that future earnings will be substantially larger. Entire sectors are valued not on what they produce today, but on what they are expected to produce tomorrow.

There is nothing inherently irrational about this. Provided tomorrow is indeed larger than today. But what if the energetic foundations supporting that growth become progressively harder to sustain? What if the economy is not merely a financial system, but an energy system? What if fiat currency is in truth a currency backed by the laws of thermodynamics (the first two laws at least).

For decades we have spoken about the dollar as though it exists independently of the physical world. Yet beneath every transaction sits a more fundamental reality.

Economies do not run on money. They run on energy. Money merely allocates claims upon it.

A dollar cannot move a truck. A euro cannot fertilise a field. A pound cannot smelt steel. Only energy can do those things. Financial systems work because they are ultimately claims upon future production, and future production itself is nothing more than organised energy transformed into useful work.

Seen from this perspective, fiat currency begins to look less like a store of value and more like a claim on future energy flows.

This may explain why debt expands so naturally during periods of energetic growth. The future really is larger than the present. More energy becomes available. More production becomes possible. More debt can be serviced.

But what happens when the energetic foundations stop expanding at the same pace?

The question is not merely financial. It is thermodynamic.

This is the disconnect that increasingly fascinates me. And suggests that we are likely to see a complete shift in our economic models and monetary system long before 42 matters.

Financial markets appear to be pricing a future of perpetual expansion while the physical systems underpinning that expansion remain finite. One worldview assumes continuation. The other implies constraint. Both cannot be true indefinitely.

But the substack response to this observation is usually predictable (in the kindest possible sense). Technology will replace oil. Wind turbines, solar farms, batteries will all replace fuel tanks. The energy transition will solve the arithmetic.

Perhaps. But this response often rests upon a subtle misunderstanding.

Energy is not electricity. And electricity is not oil.

The distinction sounds obvious, but often the conversation treats them as interchangeable.

Oil is not simply a fuel for cars. It is the foundation of global logistics, aviation, petrochemicals, industrial agriculture, mining, road construction, plastics, pharmaceuticals and countless other processes that modern life depends upon. It is embedded so deeply within the industrial system that arguments around substitution tend to miss the mark.

Oil is energetically dense because it obeys the first law of thermodynamics. It is ancient sunlight stored beneath the Earth’s surface and compressed over geological time into one of the most concentrated energy sources civilisation has ever discovered. Time made it and only time can make it again. What can be formed over 42 million years can be burned in 42.

And while electricity is enormously useful, usefulness and equivalence are not the same thing.

A wind turbine can generate electricity. It cannot mine the materials required to build itself. A solar panel can produce power. It cannot manufacture fertiliser. A battery can store energy. It cannot replace the density and portability of liquid fuels across every industrial process simultaneously.

This does not mean renewable energy is worthless. Far from it. Renewables may prove essential. But essential and sufficient are very different things. Essential keeps the lights on, sufficient propels us forwards.

The challenge facing civilisation is not simply replacing one source of electricity with another. It is replacing the energetic foundation of an industrial civilisation built upon dense, transportable fossil fuels irreplaceable due to the laws of physics and nature.

That is a vastly larger undertaking. The deeper issue is one of thermodynamics. Civilisation does not run on energy, but rather surplus energy. The question is not whether alternative energy systems can generate power. The question is whether they can recreate the surplus that built industrial civilisation itself.

That remains uncertain especially given renewables provide electricity, not the feedstock for industry.

What seems increasingly certain is that the arithmetic cannot be wished away. The world can diversify. It can innovate. It can improve efficiency. It can deploy renewable energy at unprecedented scale.

Yet none of these actions alter the fact that civilisation was built upon a finite inheritance of concentrated energy. We can survive and prosper no doubt, but economic growth requires increased energy consumption (at least it always has in the past) and the gap that will be created by declining oil and gas is immense.

Perhaps this is why the number forty-two lingers in my mind. Not because it tells us when oil runs out or because it predicts collapse. But because it reminds us that the physical world still exists beneath our financial abstractions, political promises and technological optimism.

Deep Thought spent seven and a half million years calculating the answer to the Ultimate Question of Life, the Universe and Everything.

Human civilisation arrived at the same answer with little more than an IEA reserve report and a calculator.

42

The difference is that this time we know the question. How long can a civilisation built upon finite energy continue behaving as though growth has no limits?

The arithmetic is simple.

The answer may shape the rest of the century.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

In Artificial Intelligence there is a growing belief that civilisation has discovered something powerful enough to overcome the constraints that defined the previous era. Something transformative, disruptive, the early stages of a new economic paradigm with near limitless possibilities.

So absolute is this belief, that the market capitalisation of a single chip maker (Nvidia) is worth over three times the collective value of every mining company on earth. The financial value assigned to the digital future now vastly exceeds the value assigned to the physical systems that sustain it.

We truly are entering a new paradigm.

Or so the story goes…

But beneath the spectacle of AI lies an immense contradiction. The technology being sold as humanity’s escape from material limits may in fact represent the final and most extreme expression of them. The supposedly weightless future of artificial intelligence is emerging from a civilisation already straining under the pressures of energy decline, debt saturation, institutional decay, political fragmentation and demographic headwinds.

Far from transcending physical reality, AI may become the system through which a contracting civilisation attempts to manage its own instability.

This is the AI paradox.

The more society turns toward artificial intelligence as the solution to stagnation, the more dependent it becomes on the very physical systems that are themselves entering crisis.

The myth of digital transcendence rests on an illusion. Modern societies increasingly perceive the digital world as detached from the physical one. Information exists everywhere and nowhere at once, floating in the ether. Even money has lost its physicality. In an economy increasingly mediated through screens, the modern world begins to feel detached from material reality. And now intelligence itself has been liberated from the physical world.

But every digital action has a physical cost.

Every AI model sits inside enormous data centres consuming industrial quantities of electricity. Every training run requires semiconductors manufactured through one of the most complex and globally fragile industrial supply chains ever constructed. Every layer of computation depends on copper, lithium, rare earth minerals, water cooling systems, shipping networks, stable grids and continuous capital flows. Artificial intelligence is not floating above material reality. It is deeply embedded within it.

In truth, AI may become the most energy-intensive infrastructure civilisation has ever attempted to build.

This reality remains largely hidden because modern economies have become masters of abstraction, hiding physical dependence behind interfaces. But the physical systems remain underneath the illusion, growing larger and more fragile even as they disappear from public consciousness. The phrase “the cloud” itself captures the deception perfectly. There is no cloud. There are only warehouses full of servers consuming rivers of electricity.

Artificial intelligence intensifies this contradiction dramatically. The larger the models become, the greater the computational requirements. The greater the computational requirements, the greater the energy demand. As AI competition accelerates between corporations and states, the infrastructure race becomes immense. Vast data centres are now being constructed at a pace that increasingly resembles industrial wartime mobilisation. Power grids are being redesigned around anticipated AI demand.

The future advertised as digital is rapidly becoming electrical.

This would already be significant in a stable civilisation. But the deeper problem is timing.

AI is not emerging during a new age of energetic expansion comparable to the rise of oil in the twentieth century. It is emerging precisely as the energetic foundations of industrial civilisation are weakening. The great conventional oil discoveries that powered the global growth era largely belong to the past. Extraction becomes increasingly expensive, financially and energetically. Western economies rely on deficit spending and debt creation to simulate prosperity that real productivity can no longer generate organically. Infrastructure ages, supply chains are strained, political systems begin to splinter under rising internal pressures. Ageing generations are replaced by the next, but the next are disillusioned with the old institutions around them.

In other words, civilisation is attempting to build its most computationally intensive system at the exact moment the surplus energy that enabled previous leaps in complexity tightens.

This matters because complexity is never free.

Every advanced civilisation in history has expanded administrative, technological and organisational complexity in order to solve problems created by previous layers of complexity. Initially this works. Complexity creates efficiency, enables scale, stabilises growth. But eventually the maintenance costs of the system itself begins to consume larger and larger portions of societal resources. At a certain point, complexity no longer solves decline. It becomes an overhead that fosters decline.

Artificial intelligence may represent the ultimate expression of this pattern.

The optimistic interpretation is that AI will solve all of our problems through a new explosion of innovation and efficiency. But there is another possibility. AI may emerge not because civilisation is entering a new age of expansion, but because existing systems have become too complex, unstable and expensive for humans alone to manage.

Seen this way, artificial intelligence begins to look less like a liberation technology propelling us into the future and more like a coordination technology designed to manage the consequences of the past.

The distinction is critical.

Throughout the twentieth century, technology largely expanded human autonomy. Cheap energy enabled mass mobility, home ownership, rising consumption and broad participation in economic growth. Technological systems served populations growing wealthier and more independent. But in an age of constrained energy, technology could shift function. Rather than distributing abundance, it might well manage limitation.

This shift is already visible if you look closely enough.

Algorithms increasingly govern access to information, finance, employment, insurance, credit and public visibility. Digital systems monitor behaviour continuously - ‘hey Siri’ only works when your device always listens. Institutions increasingly seek real-time data flows to maintain social and economic stability. Governments and corporations now pursue predictive systems capable of anticipating behaviour before disruption occurs.

Artificial intelligence supercharges this process.

The same systems capable of generating productivity gains are also capable of unprecedented behavioural analysis and social coordination. AI can monitor consumption patterns, financial transactions, movement, speech, sentiment and compliance at scales impossible for human bureaucracies. In a stable, surplus-rich civilisation, this capacity may appear merely commercial. In a stressed civilisation confronting energy, financial and political pressures simultaneously, the incentives change entirely.

Control becomes economically rational.

This is where the AI paradox converges with the deeper architecture of the Long Convergence.

A civilisation entering structural limits cannot preserve twentieth-century expectations of liberty indefinitely. Under such conditions, technological systems increasingly evolve but not toward freedom, toward management.

The critical point is that this process does not require conspiracy, but rather, it emerges naturally from systemic incentives.

A society facing instability will naturally seek coordination. A financial system facing volatility seeks stability and visibility. Governments facing unrest seek predictability and oversight to protect the status quo. Corporations facing shrinking margins seek automation to increase efficiency and reduce costs. Central banks facing monetary fragility seek increasingly programmable and observable financial systems through which economic activity can be monitored and influenced more directly.

AI satisfies all of these demands simultaneously.

The result is a profound historical inversion.

Throughout most of modern history, intelligence was constrained by energy. Human societies could only organise complexity up to the level permitted by available surplus energy. Non-renewable primary energy (oil, gas, coal) expanded those limits enormously but temporarily, allowing industrial civilisation to scale beyond anything previously imaginable. Now, as surplus energy slows and shrinks, civilisation increasingly turns toward artificial intelligence, intentionally or not, to preserve levels of complexity that may no longer be organically sustainable.

In effect, machine intelligence becomes a substitute for declining civilisational resilience.

This creates a strange and unsettling possibility. The age of AI may not represent the next stage of human ascent. It may represent the stabilisation system for a civilisation that is in energetic decline.

That would explain much about the emerging character of technological development. Despite rhetoric about creativity and liberation, much of the actual deployment of AI concentrates around optimisation, monitoring, prediction, automation and control. The dominant commercial uses are not utopian. They are managerial.

The machine is increasingly being asked to coordinate a civilisation too large, indebted and fragile to coordinate itself.

This also explains why AI and digital currency systems are likely to converge. Once economies become fully digitised, intelligence systems gain the ability not merely to observe economic behaviour, but to shape it dynamically. Consumption, access, carbon accounting, behavioural incentives and programmable finance all become technically interoperable within the same digital architecture.

In this alternative view of the future, the infrastructure of a digital cage emerges through the incremental logic of efficiency, security and stability rather than dramatic tyranny.

Most people imagine authoritarian systems arriving visibly, through force or overt political rupture. But I suspect advanced technological societies are unlikely to move in that manner. Control more likely emerges softly through dependency, systems become too convenient to refuse, too integrated to escape and too necessary to challenge.

Artificial intelligence accelerates this transition because it lowers the administrative cost of managing complexity. 8 Billion people reliant on a complex integrated industrial system, at the end of the age of oil, at the end of the age of fiat currency.

This is the deeper paradox. The more unstable civilisation becomes, the more valuable AI becomes. Yet the very instability driving AI adoption may itself be partly the product of the same declining energetic and economic foundations that AI cannot ultimately solve.

No intelligence system can repeal thermodynamics. No algorithm can manufacture infinite physical growth inside a finite material system. Technology can redistribute pressures, delay consequences, increase efficiency but it cannot permanently separate civilisation from the energetic foundations upon which civilisation rests.

The dream of artificial intelligence ultimately collides with the same reality that shaped every previous era of human history.

Energy is destiny.

The twenty-first century may therefore be remembered not as the moment machines surpassed humanity, but as the moment industrial civilisation attempted to use machine intelligence to navigate the end of the growth age that created it.

If so, the inversion between expectation and reality may prove historic.

But that possibility remains almost entirely absent from mainstream discussion because modern societies remain psychologically committed to the mythology of progress, of infinite growth. We continue to assume that technological sophistication automatically signals civilisational health. But history suggests this may not be the case. Some societies become most elaborate precisely as underlying stability begins to fracture.

Rome responded to declining systemic resilience with rising systemic management. By the third and fourth centuries AD, Rome had developed an enormous state apparatus to manage mounting instability. Tax systems became increasingly elaborate. Bureaucracy expanded dramatically. The empire created more complex administrative divisions, larger standing armies, extensive logistics networks and tighter systems of population control.

The USSR achieved extraordinary technological sophistication in specific domains, yet beneath this sat a stagnating economic base with declining productivity and worsening systemic rigidity. By the 1970s and 1980s, the Soviet state increasingly relied on bureaucratic management, data collection and central coordination to compensate for a system losing adaptive vitality. The administrative machinery grew larger precisely because organic economic dynamism was fading.

The late stages of empire produce extraordinary complexity alongside deep structural exhaustion. Systems grow larger and bureaucracy thickens all while confidence weakens, resilience fades and vitality declines.

Artificial intelligence may become the defining technology of such a phase.

Not the engine of limitless abundance we have been told expect, but the operating system through which a civilisation attempts to manage its own decline.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

Modern finance drowns us in numbers too large to grasp. Millions, billions, trillions, the figures blur into abstraction, and most people disconnect. They assume the system is too complex to understand, too vast to fail, and that somehow it will keep working because, well, it always has.

But one number cannot be ignored. Global debt, the sum of governments, households, and corporations, now exceeds $300 trillion ($356 Trillion as at May 2026). That is more than three times the size of the world economy. It represents the largest pile of promises humanity has ever written to itself.

The true scale of future claims is vastly larger once unfunded pensions, healthcare promises, entitlement obligations, and contingent liabilities are included. At that point the numbers become almost meaningless in ordinary human terms, stretching toward two quadrillion and far beyond the productive capacity of any plausible future economy to redeem them in real terms.

But they are not just meaningless numbers. They are assumptions about the future, that tomorrow will always deliver more goods, more services, more income. Every mortgage assumes future energy to manufacture bricks, power supply chains, and feed workers. Every sovereign bond assumes future energy to maintain armies, hospitals, and pensions. Every dollar of debt is a forward contract on energy.

For two centuries this assumption held. Coal, oil, and gas expanded faster than our debts. Cheap, high-EROEI fossil fuels allowed promises to be kept and wealth to accumulate. But that era is ending. Supergiant oil fields are in decline. New discoveries are smaller, deeper, dirtier, and more costly to exploit. Net energy (the surplus left after the energy cost of extraction) is falling. The foundation beneath our financial system is shrinking.

And in this lies a deeper problem: all modern money is born as debt. Commercial banks create deposits when they issue loans; central banks create reserves by keystroke. In both cases, money enters circulation as an obligation, tethered to the expectation of repayment with interest. Money is therefore not a neutral medium. It is a system of promises about the future, promises that assume the future will be, indeed must be, bigger than the present.

That design worked when the energy base was expanding. Each year the real economy grew large enough to honour yesterday’s promises. Credit and growth reinforced one another, producing the illusion of stability. But once surplus energy peaks, the mechanism reverses. With less energy available tomorrow than today, the future cannot redeem the claims created in the present. The very medium of exchange becomes unstable, because it presupposes growth that no longer exists.

No amount of monetary innovation can escape this collision. Printing currency cannot refill a depleted oil field. Spreadsheets cannot raise net EROEI. When hundreds of trillions in claims collide with the physics of a shrinking energy base, the outcome is inevitable: the promises will be broken.

The breaking likely won’t happen in a single crash. It is more likely to be a slow violence.

Wages will stagnate as prices creep upward. Pensions buy less each year. Taxes will rise. Services fray, infrastructure crumbles, and waiting lists grow longer. Young people inherit diminished options, realising that the future pledged to their parents will not be delivered to them. This is how debt overhang works through a system, through inflation, austerity, defaults, and devaluation. All are different words for broken promises.

In the end, there are only three ways such promises can be resolved. They can be defaulted upon outright, diluted through debasement, or managed through forms of rationing and control.

However, default destroys trust, debasement destroys confidence. Of the three, rationing is the only path capable of preserving systemic continuity without immediate collapse.

When promises exceed what physics can deliver, logic suggests money must be redefined as an instrument of allocation and control. The tragedy is that most people will never see this coming. The erosion is too slow, too technical, too hidden in the language of policy. They will feel it only in their diminished pensions, their shrinking purchasing power, their vanishing expectations. They will still hope for recovery, still trust in rescue, still believe in growth. But recovery requires surplus energy, and surplus energy is gone.

The deeper problem is not just that the debts became too large. It is that the monetary system itself was born during the greatest energetic expansion in human history and still behaves as though that expansion will continue indefinitely.

Modern fiat currency did not emerge in isolation from the physical world. It emerged alongside an extraordinary surge in surplus energy, particularly from oil. The post-war financial order was constructed during a period when industrial civilisation gained access to energy so abundant, so cheap, and so energetically profitable that growth ceased to appear conditional at all. Under those circumstances, a debt-based monetary system functioned remarkably well because the future genuinely was larger than the present.

This is the crucial point that is so often misunderstood in discussions about fiat money. Modern currencies were never truly “backed by nothing.” They were backed by an expanding industrial system capable of transforming increasing quantities of concentrated energy into goods, services, infrastructure, and economic output. The move away from gold in the early 1970s did not decouple money from reality. It merely changed the nature of the thing anchoring it. Instead of being constrained by a scarce metal, money became implicitly tethered to future growth itself, and future growth rested overwhelmingly upon expanding access to dense fossil fuel energy.

The abundance was so immense, and the expansion so relentless, that it created the illusion of permanence, it vindicated the absence of a monetary anchor, and created an illusion we continue to inhabit today.

The twentieth century witnessed perhaps the greatest energetic windfall any civilisation will ever experience. Giant conventional oil fields delivered extraordinary energy returns with minimal effort. Entire economies expanded atop this inheritance. Economies, populations and markets surged, and debt itself became normalised because the underlying energy surplus made repayment increasingly plausible. Credit could continuously expand because the productive base beneath it expanded even faster.

In this environment, financial instability was masked. Excess debt could be inflated away through future growth. Governments could refinance obligations against expanding tax bases. Asset prices could continue climbing because each generation inherited a larger economic system than the one before it. Expansion concealed fragility.

What mattered was not the existence of oil, but the quality of the surplus it delivered. The great conventional fields of the twentieth century did not just produce energy. They produced vast amounts of net energy after the costs of extraction had been paid. A tiny energetic investment yielded enormous returns, leaving society with a tremendous surplus available for everything else: finance, healthcare, education, technology, military, pensions, bureaucracy, consumption, and complexity itself.

That surplus was civilisation’s real collateral. And for decades it appeared effectively limitless.

But systems built during periods of abundance easily mistake temporary conditions for permanent reality. Financial systems are no exception. The monetary architecture of the modern world still assumes the continuation of conditions that are quietly fading beneath it.

The great supergiant oil fields are ageing. New discoveries are smaller, deeper, more technically difficult, and energetically weaker than the fields that built the modern age. The industry increasingly turns toward shale, tar sands, ultra-deepwater reserves, and fractured rock not because these are superior resources, but because the easier reservoirs have already been consumed. Gross production volumes may remain high, and the industry often presents this as evidence of continued abundance, but the energetic quality of what remains continues to deteriorate.

This distinction between gross energy and surplus energy is fundamental because civilisations do not run on production statistics. They run on what remains after extraction costs have been paid. A society fuelled by high surplus energy possesses extraordinary flexibility. A society forced to spend increasing amounts of energy merely obtaining more energy begins slowly cannibalising the surplus that once sustained its broader complexity.

And this is precisely where the financial system begins to destabilise.

The debt expansion of recent decades is often portrayed as a political failure, a consequence of irresponsible governments, over zealous central bankers, a corruption of capitalism or speculative excess. Certainly those forces matter. But beneath them lies something more structural. Debt has exploded because the system increasingly requires synthetic financial expansion to compensate for weakening energetic surplus in the real economy. Stymied organic growth is obscured by overt financialisation of asset classes.

The shale revolution illustrates this contradiction perfectly. Publicly it was presented as proof of renewed abundance, a technological triumph capable of securing American energy independence for generations. Yee-haw!

Yet economically the industry survived largely through oceans of cheap credit and investor subsidy. Shale wells decline with extraordinary speed, requiring constant drilling merely to sustain output. The energy returns are vastly lower than the conventional giants that preceded them, and profitability remained elusive for much of the sector even during years of high production. The apparent renaissance was, in many respects, a financial system compensating for a deteriorating energy system.

The same pattern now exists across the broader economy. Debt rises faster than productive output because future claims are multiplying more rapidly than the energetic surplus capable of honouring them. The system continues behaving as though the future will expand indefinitely because it has no mechanism for functioning otherwise.

This is what makes the current moment so historically significant. We are approaching the point where the assumptions embedded within the monetary system begin colliding directly with the physical realities beneath civilisation itself.

Money, in its modern form, is fundamentally a claim on future production. Debt extends that logic further still. It is a claim on future surplus before that surplus exists. Under conditions of expanding energy abundance, these claims can continue multiplying because the productive base expands fast enough to absorb them. But once the energy base begins to plateau or weaken, the relationship reverses. Financial claims continue compounding while the physical capacity required to redeem them stagnates.

At that point the system enters a dangerous phase of divergence.

On one side sits the vast mountain of claims: sovereign bonds, mortgages, pensions, derivatives, healthcare obligations, corporate debt, unfunded liabilities, and asset valuations all dependent upon future growth.

On the other side sits the real economy, increasingly constrained by declining energetic returns, ageing demographics, resource depletion, and slowing productivity growth.

The distance between these two worlds is now measured in the hundreds of trillions.

And no amount of monetary engineering can fully reconcile them because the contradiction is no longer primarily financial. It is thermodynamic.

This is why the language of economics increasingly feels detached from lived reality. Official growth figures continue upward while living standards stagnate. Asset markets inflate while younger generations lose access to housing. Financial wealth expands while infrastructure decays. Productivity weakens even as debt accelerates. The charts still rise, but the civilisation beneath them begins to hollow out.

The appearance of continuity disguises the erosion underneath.

This is also why central banks and governments appear trapped within permanent intervention, whether actual or implied readiness. Interest rates cannot rise significantly without destabilising debt markets. Deficits cannot close without threatening growth. Asset prices cannot fall without exposing systemic fragility. Monetary expansion therefore becomes continuous because contraction itself has become politically and financially intolerable.

But monetary expansion cannot create real surplus. It can only redistribute claims upon it.

No amount of printing currency or lowering interest rates can refill depleted oil fields or restore high EROEI energy systems. Financial liquidity cannot recreate the extraordinary energetic inheritance that made perpetual expansion appear normal throughout the twentieth century.

The problem is not simply that the world accumulated too much debt. The deeper problem is that modern finance evolved within a temporary window of exceptional surplus and mistook that surplus for permanence.

That window is now narrowing.

And as it narrows, the character of money itself is beginning to show signs of change.

In periods of abundant growth, money can remain relatively open, permissive, and decentralised because expansion absorbs instability. But constrained systems require tighter coordination. As surplus shrinks, the management of flows becomes increasingly important. The financial system gradually shifts from facilitating expansion toward managing constraint.

This transition is already visible in the emergence of digital settlement systems, tokenised assets, programmable payment infrastructure, and central bank experimentation with new forms of digital money. These developments are presented as technological innovation, but beneath the language of convenience and efficiency lies a deeper adaptation taking place within the architecture of the system itself.

A civilisation entering an era of constrained surplus cannot operate indefinitely with a monetary framework designed for limitless expansion.

That is the quiet reality now unfolding beneath modern finance.

The age of abundance did not just create prosperity. It created the assumptions embedded within money itself. Fiat currency was the monetary expression of an expanding energy civilisation, a system that functioned because the future consistently contained more surplus than the past.

But when the future ceases to expand fast enough to redeem the claims written against it, the entire structure begins to strain. The promises will not all be honoured exactly as written because they cannot be. The physics will not allow it.

And so the system will have no option but to adapt. The age of easy surplus made modern finance possible. Its decline will reshape money itself.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

The environmental agenda could have been built around any number of ecological crises, each one worthy of global attention. The evidence is overwhelming that we are degrading the very systems that make human life possible.

There are many causes that should foster outrage in the hearts of humankind. Among these are: Deforestation, species extinction, soil degradation, river pollution, collapsing fisheries, ocean plastics, micro plastics, air pollution, insect loss, loss of bio diversity.

Each of these deserve their own article rather than a passing mention and many are urgent in ways that will directly impact food, water, and health long before atmospheric CO₂ reaches any specific target. They are issues of man made ecological damage which are as morally indefensible, if not more so, than climate change.

Yet none of these became the overwhelming focus of global policy. Carbon did.

The physics of greenhouse gases is well established: CO₂ traps heat, and rising concentrations contribute to a warming planet. But the way climate science operates inside political, funding, and media systems shapes which findings are amplified and which are sidelined. It is the politicisation of science that concerns me the most.

I do not wish to imply that that climate change is either unreal or unimportant. The physics of warming is well-established, and its consequences are serious but scientific truth does not prevent political utility. Climate policy has become the primary framework through which governments interpret energy scarcity and legitimise long-term policies.

Carbon dioxide (‘carbon’) is not merely a (legally defined) pollutant, it is the only variable that maps cleanly onto every act of energy use and therefore every act of modern life. Its narrative power lies in this dual role being both scientifically valid, and politically charged. The moral framing of an invisible yet existential threat also lends itself naturally to systems of policy coordination and behavioural guidance.

In this manner, the political centrality of carbon may stem from two overlapping realities: climate risk itself, and the extraordinary administrative usefulness of carbon as a universal metric.

If one were seeking to design a single environmental variable to serve as the linchpin for a global system of monitoring and managing consumption, you could hardly do better than carbon dioxide. CO₂ is uniquely suited to the role it now plays, not solely because of its climatic impact, but because it is the perfect metric for a system seeking to monitor and manage consumption.

Carbon can be counted for almost everything humans do whether it is the fuel you burn in your car, the electricity that lights your home, the fertiliser that grows your food or the steel, concrete, plastics, and glass in the buildings you live and work in. Each of these activities has an associated carbon value that can be calculated, recorded, and assigned to a ledger.

In a world increasingly forced toward lower energy consumption by geological constraint, there is no more effective metric for governing economic life than carbon itself, the very byproduct of the energy system now reaching the limits of its abundance.

The themes explored throughout this series are not isolated observations, but different expressions of the same underlying reality. In the recent article The Thermodynamic Trap, I examined how civilisation is ultimately constrained not by ideology or economics, but by the physical limits of energy itself. In The Permian Paradox, I explored how declining energetic returns force modern economies to rely on rising debt and complexity merely to sustain output. In The Death of the Supergiants, I examined the exhaustion of the giant high EROEI oil fields that powered the age of abundance, and the inability of newer resources to replicate their extraordinary surplus. In An Idea Once Ahead of Its Time, I explored how systems often begin constructing the architecture of adaptation long before the public fully understands the pressures making that adaptation necessary. And in Money Was Never Backed By Nothing, I argued that money and debt are ultimately claims on energetic surplus, and that financial instability emerges when those surplus foundations begin to erode.

Viewed together, these pressures begin to converge. The world is not simply looking to decarbonise because of climate policy alone, nor purely because of market preference or technological progress. It is entering a period in which energy abundance itself is becoming harder to sustain, while the systems built upon that abundance increasingly require measurement, coordination, and management in order to remain stable.

Carbon sits precisely at the intersection of these realities. It links energy, consumption, industry, finance, and individual behaviour through a single measurable variable. That is what makes it not merely environmentally significant, but systemically important.

In terms of use as a metric, carbon can be standardised, a tonne of CO₂ in Australia is the same as a tonne of CO₂ in Argentina. This gives policymakers and economists a standardised unit to measure, tax, or limit. This universality makes it the perfect foundation for global treaties, carbon markets, and perhaps more importantly, integrated data systems.

Unlike deforestation or microplastics, CO₂ emissions can be estimated on a personal level down to that of an individual citizen. Your “carbon footprint” is a concept tailor-made for the age of personal data tracking. It translates an abstract global phenomenon into a moral and measurable scorecard for your lifestyle. Our very act of breathing creates carbon dioxide (biogenic and therefore carbon neutral it should be noted), making it a very personal, if invisible, part of our existence.

Other environmental crises resist this kind of neat accounting. Soil degradation depends on local conditions and decades of land use. Species extinction is a web of causes that can’t be converted into a single, universal unit. Plastic waste varies by type, toxicity, and ecosystem impact. These problems are serious and sometimes existential, but they are fragmented, location-specific, and resistant to real-time individual monitoring.

Carbon is very different in that respect. Its measurement can be automated. Its values can be embedded in prices. It can be integrated into every purchase, every supply chain, and every financial transaction. And because it applies everywhere, it can unite the actions of billions of people under a single, simplified framework.

From a systemic control perspective, this is an extraordinary feature. In the same way GDP became the singular measure of economic performance, crowding out more nuanced indicators, carbon has become the singular measure of environmental performance. What GDP did for economic centralisation, CO₂ is now doing for environmental centralisation.

Seen in this light, the elevation of CO₂ from one environmental problem among many to a central organising principle of global policy is not a scientific development. It is a structural one. Positioning of climate policy gives the moral mandate while carbon provides the universal metric.

Elevating carbon as the primary measure of environmental success or failure has primed billions of people to accept measurement of their behaviour for a moral cause. The perfect control variable and the tools to make it binding are converging.

The emphasis on individual carbon accountability also subtly shifts focus away from structural dependency. Systemic limits become framed increasingly through the language of personal behaviour and consumption. It shifts responsibility downward. Systemic limits are able to be reframed as individual excess. Failure can no longer be seen as structural, but behavioural. In this way, carbon has the ability to function as both scapegoat and scorecard, a soft weapon for hard limits.

And I fear the models will harden into mandates over time, the next question quietly emerges and it is a fascinating one. How might compliance be ensured?

In the background, new forms of digital accounting are already being conceived: financial systems that can measure, verify, and potentially limit consumption in real time. What began as climate modelling has been evolving toward behavioural modelling. The infrastructure capable of translating moral obligation into measurable behavioural signals is already quietly emerging.

Once the thermodynamic and geological realities take hold, regardless of climate change, we will inevitably enter an age of relative scarcity. A moralised control variable linked directly to the limitations of the oil age becomes a compelling tool for policy makers.

It is hard to envisage while the cracks in the financial and social system are not yet large enough to expose these age-defining pressures, however, they are likely coming. When they do, the age of persuasion could easily tip towards enforcement. To turn moral restraint into enforceable policy, the system will need a new kind of financial system, one that can count, one that can remember.

The infrastructure for such systems is already developing quietly within finance, payments, and digital governance. Whether these capabilities remain optional tools or evolve into more formal mechanisms of coordination may become one of the defining political questions of the coming decades.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

Money is a human invention. Just a clever tool of a clever species. A neutral construct that sits above the real world.

Nothing in this description makes it real.

And that offers a certain psychological comfort. If money is merely a human invention, then surely the rules can simply be rewritten when the system breaks. We can reform it, move on, and continue as before.

I understand that instinct. I really do.

Unfortunately there’s more to it than that, and more consequences than just reforming the monetary system as if it were a flickering light bulb in an otherwise solid home.

In my recent article (Money was Never Backed By Nothing) I discussed why money is not abstract, and why it is anything but neutral. Once you strip away the stories we tell ourselves, along with the complexity of markets, policy, finance, and price signals, something older and more physical remains. Beneath all the mathematics and all the politics, money is simply a claim on energy.

Every act in the real economy requires energy to occur. To mine the ore, to smelt the metal, to fabricate the semiconductor, to assemble the vehicle, to transport it across oceans, to light the warehouses and supermarkets where it is sold, it is all energy. Even the service economy rests on the same foundation: offices are cooled and heated, servers are powered, cities illuminated, supply chains maintained. GDP, when you look closely, is nothing more than an elaborate measure of energy being transformed into work.

This is why, for nearly two centuries, the global economy (as expressed in GDP) and global energy consumption have moved in near-perfect synchrony. When energy rises, GDP rises; when energy contracts, GDP contracts (or vice versa perhaps). Our prosperity is not a financial achievement. It is a thermodynamic one.

Once you see this clearly, another truth emerges. One that is unsettling, obvious, and likely ends the fiat currency era. This is not a premonition but rather a mathematic and thermodynamic inevitability.

As money is a claim on the energy, embodied in goods and services, it follows that debt is a claim on future energy.

A loan presumes that tomorrow will satisfy the present, on a global scale, all debt must presume that the economy will be bigger than today’s to satisfy the obligation. A mortgage assumes that the future will contain more energy, more productivity, more capacity to repay. Every bond, every pension, every government promise rests on the same quiet assumption: that tomorrow will bring more surplus energy than today.

Only on this premise can an indebted system hope to maintain the perception of solvency.

For most of the oil age, this was not an unreasonable belief. Early oil fields delivered energy return ratios that seem almost mythic today. A barrel’s worth of energy spent on drilling and pumping might bring back fifty or even a hundred barrels in return. That extraordinary energetic surplus did not just power engines and factories. It powered credit. It made long-term promises believable. It made compound interest serviceable and it made the financial world appear stable.

Economic expansion, soaring consumption, the birth of welfare states, the explosion of global trade, the security of pensions, all of it rode on the back of enormous energy surpluses. Cheap, abundant oil made debt safe, because the future really was bigger than the past. We were not just discovering new fields; we were discovering new capacity for society itself.

But the surpluses that underwrote this world are fading. As the great oil basins depleted and technology reached further into deepwater, shale, tar sands, and fractured rock, our energy returned for energy invested (EROEI) began to fall. The decline was not dramatic, and that made it more dangerous. The economy continued to grow on paper, gross energy output stayed at record highs, but underneath, the energetic foundation was thinning. It became harder and harder to extract the next barrel, the next unit of gas, the next tonne of coal.

And as net energy declined, something predictable and yet almost invisible happened: debt exploded.

That is not coincidental.

Credit had always grown, but now it began to expand faster than the economy it was supposed to represent. This was no accident of policy or failure of regulation. It was the system compensating for a loss it could not acknowledge. When energy surpluses shrink, the financial system must expand its claims on the future in order to maintain the appearance of prosperity in the present. Debt becomes a substitute for surplus energy: a way to pull tomorrow onto today’s balance sheets.

Nowhere is this dynamic clearer than in the American shale boom. The triumphal narrative of the 2010s, the story of energy independence, of technological ingenuity, of renewed abundance, was built on credit, not on surplus. Shale wells decline so quickly, and their net energy is so marginal, that the industry struggles to generate enough surplus to sustain itself. It required endless borrowing to drill, endless refinancing to expand, endless investor capital to delay the reckoning. What looked like a renaissance was in fact the financial system propping up an energy source too weak to stand on its own.

This is the moment when the illusion becomes impossible to ignore. A civilisation that once financed its future out of energy abundance now finances it out of energy deficit. We issue more and more claims from government bonds, corporate debt, mortgages, derivatives, unfunded liabilities, all against a future that contains less and less surplus energy. The mathematics no longer work. The future cannot repay the present. The linear promises of the financial system have collided with the physical limits of the energy system, and the financial system is losing.

This is the real crisis of our time. Not inflation or lack of growth. Not mismanagement. Those are surface symptoms of a deeper rupture: the world is attempting to redeem claims on a future that no longer exists. Pensions, sovereign debt, corporate valuations, insurance models, the very concept of long-term compounding, all were built in an era when the energy base expanded each year. As that expansion ends, every financial promise becomes unstable.

And this is why the system is turning toward tools of digital control. When you can no longer expand the energetic pie, you must manage how the slices are distributed and to do that, the system requires perfect visibility, perfect traceability, perfect compliance.

Money was always a claim on energy. Debt was always a claim on future energy. The crisis is simply that the future no longer contains the surplus required to honour the claims we have made upon it. And so the system will not shrink voluntarily. It will change shape and enforce discipline. It will become digital, programmable, conditional. Not to enhance prosperity, but to preserve order as the underlying reality of decline asserts itself. The instruments through which this discipline is enforced will appear technical, neutral, and administrative.

The money illusion collapses the moment you understand that money is not a financial abstraction but an energetic claim. After that, the rest of the story writes itself.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

In 2022, the International Energy Agency published a ten-point plan for how to reduce oil consumption in the event of a major supply disruption. It was framed as a temporary response to crisis. Read more closely, it looks like something else entirely.

Presented as a set of temporary and pragmatic recommendations, it appears at first glance to be a conventional policy response to an acute geopolitical shock. Yet beneath its surface lies something far more significant. It is not merely a contingency plan. It is a behavioural blueprint for a world in which energy abundance can no longer be assumed.

The premise itself is revealing. A disruption of twenty percent is not framed as an unthinkable catastrophe, but as a plausible scenario requiring immediate adaptation. The February 2026 US and Israeli strikes on Iran has created exactly this scenario where 20% of global supply is disrupted for an indefinite period.

This report signals a quiet shift in institutional thinking. For decades, the dominant narrative has been one of continuity, underpinned by technological optimism and the assumption that supply constraints would be resolved through investment, substitution, or innovation. Here, however, the emphasis is not on increasing supply but on reducing demand. The burden of adjustment falls not on production, but on behaviour.

What follows in the plan is a series of measures that, taken individually, appear modest and even reasonable. Lower speed limits on highways, encouraged working from home, restrictions on car usage in urban areas, reduced reliance on air travel, and a shift toward public and shared transport all carry a veneer of practicality. Each can be justified on grounds of efficiency, cost savings, or environmental benefit. Yet when considered together, they form a coherent pattern. Mobility is curtailed. Individual autonomy in transport is reduced. Physical presence is substituted with digital interaction. Consumption is moderated not through price signals alone, but through direct intervention in daily life.

This pattern is not accidental. It reflects a fundamental constraint that cannot be easily addressed through conventional economic mechanisms. Oil is not simply another commodity that can be replaced or expanded at will. It is a uniquely dense, portable, and versatile energy source that underpins the entire architecture of modern transport and much of global industry. As the Energy Institute’s Statistical Review makes clear, oil remains the single largest contributor to global energy demand, accounting for roughly a third of total consumption, while fossil fuels as a whole still provide over four fifths of the world’s energy supply. Despite decades of investment in alternatives, the physical foundation of civilisation has not materially shifted. The system remains structurally dependent on hydrocarbons.

In this context, a sudden reduction in supply cannot be easily offset. There is no equivalent energy source that can be mobilised at scale within the required timeframe. The only immediate lever available is demand. The ten-point plan is therefore not an expression of policy preference, but of necessity. It outlines how a complex, energy-intensive society might attempt to function with less of the resource upon which it was built.

The implications extend far beyond the immediate scenario. What is presented as a temporary response to disruption begins to resemble a template for a more permanent condition. If supply constraints were to persist or deepen, whether through geological decline, underinvestment, or geopolitical fragmentation, the measures outlined would not remain optional or short-lived. They would become structural features of the system. The distinction between emergency response and long-term policy would blur, and the management of demand would move from the margins to the centre of governance.

There is an important subtlety here that must be understood if the argument is to retain its credibility. The plan does not emerge from a desire to control behaviour for its own sake. It emerges from the recognition that behaviour must change when the physical basis of the system can no longer support existing patterns of consumption. This is not ideology imposed upon reality, but reality imposing limits upon ideology. The language of sustainability, efficiency, and climate responsibility provides a framework through which these changes can be communicated and justified, but the underlying driver is more fundamental. It is the constraint imposed by finite, declining, or increasingly costly energy.

Seen in this light, the measures take on a different character. Reducing speed limits is not simply a matter of improving safety or marginal fuel efficiency. It is a way of stretching limited resources across a larger system. Encouraging remote work is not only a reflection of technological progress, but a means of reducing the energy cost of daily economic activity. Limiting air travel and promoting rail transport reflects the stark differences in energy intensity between modes of transport, and the necessity of favouring those that are less demanding. Even the promotion of electric vehicles, often framed as a solution to oil dependence, sits within this logic. Electrification shifts the form of energy consumption, but does not eliminate the underlying constraint, particularly when the generation of that electricity remains tied to fossil fuels and the infrastructure required is itself energy-intensive.

What emerges is a picture of managed descent, a gradual, structured reduction in the energy throughput of society. The aim is not to halt activity, but to reshape it in ways that are compatible with a lower energy baseline. This requires changes not only in technology and infrastructure, but in expectations. The assumption of unrestricted mobility, of constant growth in consumption, of frictionless global connectivity begins to erode. In its place comes a more constrained model, in which access is moderated, choices are shaped, and efficiency becomes a necessity rather than an aspiration.

This transition is unlikely to be smooth. Modern economies are built on the premise of expansion. As explored in my earlier posts, growth is not merely desirable but structurally embedded in financial systems that rely on increasing output to service debt and maintain stability. A reduction in energy availability therefore has consequences that extend into the monetary domain. Slower growth, or contraction, places strain on fiscal systems, corporate balance sheets, and social contracts. The temptation, and often the immediate response, is to offset these pressures through monetary expansion, increasing debt, and policy intervention.

Yet such measures do not resolve the underlying physical constraint. They redistribute or defer its effects.

The ten-point plan can be read, therefore, as an early acknowledgement of a tension that will define the coming decades. On one side lies the physical reality of energy limits, expressed through declining returns, constrained supply, and rising costs. On the other lies a financial and political system predicated on continuous growth and expanding consumption.

Bridging this gap requires more than technological substitution. It requires a reconfiguration of behaviour at scale.

At present, the mechanisms for achieving this reconfiguration remain relatively soft. Recommendations, incentives, and social norms are deployed to encourage compliance. Public messaging frames the changes in terms of collective responsibility and shared benefit. In times of acute crisis, such approaches can be effective, as populations respond to clear and immediate threats. However, as constraints become chronic rather than episodic, the limitations of voluntary adaptation may become apparent. The question then shifts from whether behaviour must change, to how such change can be maintained consistently across large and complex societies.

It is here that the broader architecture of control begins to enter the picture, not as a conspiratorial imposition, but as a logical extension of the problem. If energy must be rationed, explicitly or implicitly, and if that rationing must be coordinated across millions of actors, then systems of monitoring, measurement, and enforcement become increasingly relevant. The tools for such systems already exist in nascent form within the digital infrastructure of modern economies. Financial transactions, mobility patterns, and consumption behaviours are already recorded, analysed, and influenced through a combination of private and public platforms.

The IEA plan does not articulate this next step. It remains within the domain of policy guidance and behavioural nudging. Yet by outlining the necessity of demand reduction, it implicitly raises the question of how such reductions can be achieved in a sustained and equitable manner. The answer, when it comes, is unlikely to be found solely in appeals to voluntary restraint.

What the plan ultimately reveals is not a grand strategy, but a constraint. It shows that when faced with a significant disruption to oil supply, the immediate response is to reduce demand through changes in behaviour, rather than to rely on rapid increases in alternative supply. It shows that the margin of flexibility within the current system is narrower than often assumed.

And, more importantly, it suggests that the future, if shaped by similar constraints, will involve not the seamless replacement of one energy system with another, but the careful management of decline.

This is the quiet reality beneath the rhetoric of transition. The world is not moving from abundance to a new form of abundance. It is ultimately moving from abundance toward constraint, and seeking to do so without triggering the instability that such a shift would ordinarily produce. The ten-point plan is a small but telling glimpse of how that process might unfold. It suggests that the future will not be defined by seamless transition, but by the careful management of constraint.

This is the defining condition of the modern age. We are, each of us, kings of the oil age. For a brief moment in history, we inherited a form of power so vast and so cheap that it elevated ordinary lives to extraordinary heights.

The average person in the developed world commands the energy of dozens of full-time workers every single day, and our entire standard of living depends on that labour continuing without interruption.

Your food, your heat, your transport, your light, your comfort, all of it is being provided by a vast system working continuously on your behalf.

You are being served, in the most literal sense. The difference is that you do not see the servants, and you do not pay them what they are worth.

Kings throughout history could command labour at scale. Entire households moved at his direction, with fields ploughed, food prepared, fires lit, water carried. His comfort depended on human labour, sometimes dozens, sometimes hundreds of people working continuously to sustain a single lifestyle.

But this was the life of a king, the highest position in the land, not the norm.

And even then, his world was constrained by the limits of energy available to him. Travel was painfully slow, food was local and seasonal, without variety. Darkness arrived each evening with the setting sun, only partially offset by candlelight or firelight. Something as simple as a hot bath required hours of preparation, with water heated manually over open fires.

Meanwhile the wider population lived in squalor. Life for the normal person was harsh, short and subservient.

Now compare that to the experience of an ordinary person today.

With the press of a button, a room is heated or cooled to a precise temperature. Light appears instantly, food arrives from across the world, prepared, packaged, and delivered to us with minimal effort and cost. Entertainment is available instantly, tailored to any preference. Water flows clean and hot. A single person can summon transport, access global knowledge, or communicate across continents in seconds, all without leaving a chair.

No king in history lived like this, and yet for the average person today, it passes without question.

What changed was not human intelligence, nor politics, nor the natural course of society. Many will put it down to technology, but that is only part of the story. What really changed is energy.

Engines, turbines, grids, and machines perform the labour that once required entire populations. They fertilise and plough fields, grow food, move goods, refine materials, generate electricity and sustain the systems that keep billions alive. We do not see this workforce, but we depend on it absolutely.

For the average person in the developed world, this energy inheritance is the equivalent of having dozens of servants working continuously, lifting, moving, heating, cooling, producing, without rest and at almost no perceived cost. A life once reserved for the highest ranks of power has become ordinary.

And like all inheritances, it is being spent.

Modern industrial life is powered by an invisible workforce we take for granted. What we experience as convenience, comfort, and productivity is, in reality, the output of a vast and tireless system of energy working silently beneath us.

For most of human history, energy meant muscle, whether human or animal, supplemented by wind, water, and fire. Output was limited by biology. A healthy human might sustain 100 watts of power, barely enough to light a modern bulb. A family with an ox or two could muster a kilowatt or so in bursts. Life remained slow, local, and constrained because energy was scarce and largely unharnessed.

Then came fossil fuels.

Coal, and later oil, delivered power at a scale that dwarfed anything muscle could offer. Today humanity consumes over one hundred million barrels of oil each day. Every 24 hours, a vast pool of geological inheritance is emptied to keep civilisation moving. Stacked end to end, those barrels would form a tower as tall as 10,000 Mount Everests and stretch a quarter of the way to the moon.

That is the daily burn rate of industrial civilisation, a column of rich black oil reaching deep into space, spent and gone in a single day, only to be repeated again tomorrow, and so on, fuelling our insatiable need for energy.

For the person in the developed world, that energy inheritance amounts to around 1,200 personal barrels of oil used across a lifetime, used across thousands of moments of travel, consumption, convenience, and comfort. This represents roughly two million kilowatt-hours of concentrated energy, equal to 2,300 years of continuous human labour.

Put differently, oil alone grants each of us the equivalent of living an entire life attended by around thirty personal servants, working around the clock, never resting, never eating, never demanding wages.

But oil is only part of the story.

Once natural gas, electricity, coal, nuclear, and the embedded energy within modern systems are included, the scale expands dramatically. A modern life in the developed world is supported not by dozens, but by over fifty invisible daily energy servants. They heat our homes, move our goods, grow our food, light our cities, and sustain the entire architecture of modern comfort.

What we call prosperity is partly the result of technological and medical innovation, but it is sustained entirely by the labour of this hidden workforce.

And if they did demand wages? At even $50 a day, thirty servants would cost over half a million dollars a year. Across an 80-year lifetime, more than $40 million. By comparison, the oil that performs the same labour costs less than $100,000.

Oil grants us a life of comparative luxury at a fraction of the cost. It truly is an inheritance being spent at an unsustainable pace.

At current rates of consumption, we are drawing down a finite resource on a timescale of decades, not centuries. Even if significant reserves remain, the conditions that allowed this level of cheap, abundant energy are unlikely to be repeated.

Over the course of a modern life, an average Westerner does not simply consume energy. They command it at a scale that would have been unimaginable to any prior civilisation.

This is our civilisation’s hidden subsidy. We regard it as wealth, progress, or efficiency, perhaps even entitlement. But it is none of those things. It is a one-time endowment of energy, stored ancient sunlight, made liquid by time and pressure.

In a single lifetime, we burn through a dense pool of energy equivalent to hundreds of millions of years of stored solar energy.

These energy slaves are not a feature of modern life; they are its foundation.

And they are finite and ageing.

Since the Industrial Revolution, global energy consumption has risen more than tenfold, the overwhelming bulk of it supplied by coal, oil, and natural gas. Despite decades of policy ambition and trillions in investment, fossil fuels still dominate the system. Even now, they provide the vast majority of global energy supply, more than 80%.

The transition away from primary energy is real in narrative, but marginal in physical terms. In reality, we use more primary (fossil) energy than at any point in history, even as renewables expand.

Which brings us back to the invisible workforce.

Despite all our talk of progress, our energy slaves still wear the same uniform. They still come overwhelmingly from hydrocarbons, those dense, portable, and exhaustible sources of stored energy. The reason for this is not profit or convenience, it is dictated by thermodynamics.

Not all energy is equal. Not in form, not in function, and not in origin.

The primary energy sources that built the modern world carry a unique advantage, one that has nothing to do with human ingenuity and everything to do with time. Oil, coal, and natural gas are not simply fuels. They are the result of millions of years of solar energy captured, stored, compressed, and transformed by geological processes far beyond anything we can replicate.

Ancient sunlight, absorbed by plants through photosynthesis, was buried, subjected to heat and pressure, and slowly converted into dense hydrocarbons. What we extract today is not current energy flow, but a vast inheritance from the deep past. Energy that arrived daily from the sun has been accumulated and concentrated across geological time into a form that is extraordinarily rich, stable, and usable.

That is what we are drawing down. Not just fuel, but compressed time on a scale that is difficult to grasp.

Nature has already done the work. It has taken diffuse, intermittent solar radiation and turned it into dense, portable, and energy-rich matter. It has effectively performed the long chain of conversions, losses, and compressions on our behalf, delivering a fuel that arrives pre-packaged with high utility and minimal effort required for use.

The difference now is that the terms are changing.

The great fields are ageing. The few dozen supergiant fields have all but died, most are as old as the baby boomer generation that enjoyed the fruit of their vast stores. The easiest reserves are undeniably gone and can never be replaced. Each new unit of energy requires more effort, more capital, and more complexity to deliver. The workforce is still vast, but it is old, energetically thin and no longer expanding in the way it once did.

And as their numbers begin to dwindle, through depletion, cost, or design, the structure they support will not gently adjust.

It will strain.

And then it will change.

The invisible workforce cannot be seen, but it can be counted. And like all finite things, it has limits.

What happens next is a question for later. For now, it is enough to recognise that it exists and that it has been doing far more of the work than we ever acknowledged.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

For most of the twentieth century, one number has held civilisation in its grip: Gross Domestic Product.

GDP is the scoreboard by which nations measure success, the mantra repeated by politicians, investors, and economists.

Growth is good. Recession is bad. If GDP is rising, the system is working.

But this number, so familiar and unquestioningly authoritative, is also profoundly dangerous. It creates the illusion of progress even as the foundations of that progress erode. It blinds societies to decline by recording activity without distinguishing between building and burning, between income and liquidation, between wealth and waste.

It reassures us we are thriving even as we eat through the seed corn of the future.

GDP was not born as a measure of prosperity. It was invented during the Second World War to calculate a nation’s capacity to produce tanks, planes, and munitions. It was a tally of throughput, not wellbeing. After the war, it was repurposed as the yardstick of national success. But its DNA never changed. GDP still counts flow, not balance. It tracks the churn of money, not the health of the system that makes money possible.

In the world of GDP, every dollar spent looks the same. Borrow to build a bridge or borrow to bail out a failing bank, both raise GDP. Drain an aquifer to irrigate crops, or invest in regenerative farming, both raise GDP. Clear a rainforest for palm oil or restore a wetland, both raise GDP.

GDP rises when cars crash and need repairing. It rises when illness requires expensive treatment. It rises when pollution must be cleaned. In the ledger of GDP, disasters are as good for the economy as innovation. What it cannot see are the foundations: ecosystems intact, households stable, energy abundant.

This blindness makes GDP the perfect cover for the debt economy. A nation can borrow aggressively, expand consumption, and declare success because GDP ticks upward. The measure treats credit-fuelled activity as prosperity, even when it is little more than the acceleration of future claims.

That is why governments worship GDP growth above all else: it gives them legitimacy. Growth is proof the system works, even when that growth is no more than borrowed time. For two centuries, the expansion of output has marched in lockstep with the expansion of fossil fuel (primary energy) consumption. Every burst of growth has been powered by a burst of energy surplus. As economic growth rises so too does energy consumption.

This makes GDP appear to be a neutral, abstract number, but in reality it is a derivative of energy throughput to deliver economic growth. And as the surplus energy from oil, gas, and coal declines, the growth that GDP worships cannot be sustained. To chase it is to chase a ghost.

Institutions like the International Energy Agency now predict a future in which GDP rises while fossil energy use falls. It is an alluring promise: prosperity without cost. But history gives us no precedent for such a separation.

very attempt to prove decoupling relies on relative decoupling in specific regions or sectors, not absolute decoupling at the global level. The UK for example will commonly cite net zero progress while outsourcing emissions to other countries.

The danger is not just that the myth that economies can grow while energy consumption falls is wrong. It is that it is believed. Entire policy regimes are built on the promise that growth can continue even as energy declines. The system clings to the number, because without growth, legitimacy collapses.

GDP is a mirage that can tell us we are richer when in fact we are poorer, that we are advancing when in fact we are retreating.

It cannot tell the difference between a society investing in its future and a society liquidating its assets to survive the present.

It cannot measure resilience, trust, or stability, it can only measure throughput. It seduces us with the illusion of permanence and makes unsustainable growth look like progress. It tells a civilisation living beyond its means that it is getting richer, when in truth it is exhausting the very foundations on which wealth depends.

GDP does more than mislead. It justifies the very architecture of debt money. Our financial system depends on perpetual expansion: money is created as debt, and that debt can only be serviced if tomorrow is bigger than today. Without the promise of growth measured and sanctified by GDP, the entire edifice crumbles.

GDP is not just a dangerous number. It functions as a legitimising device, allowing a debt-dependent, energy-constrained civilisation to defer confrontation with its own limits. And as energy declines and debt soars, it will become clear that the number was never a measure of progress, but a mask for depletion.

Rising debt is often thought of as a failure of policy or economic discipline. In reality, it reflects something deeper: a system attempting to preserve its complexity as the surplus energy that sustains it begins to thin. GDP continues to register activity, smoothing the surface and masking the strain beneath. What appears as stability is, in many cases, the financialisation of decline.

We inhabit a world governed by physical laws. These laws determine how particles interact, how objects move, how energy is stored, transferred, and ultimately used.

They operate whether we acknowledge them or not. They cannot be negotiated with, voted on, or innovated away.

Among them, the laws of thermodynamics sit at the foundation.

Two of these laws shape the very structure of civilisation itself.

They also explain, more clearly than any economic model or political narrative, why the idea of seamless energy substitution begins to break down.

The first law is absolute. Energy cannot be created or destroyed. It can only be transformed.

The second law is perhaps more consequential. Every transformation carries loss. Energy becomes less useful, entropy always increases, as order tends toward disorder.

It is this law that dictates there is no free conversion. No perfect efficiency. The second law is the quiet tax imposed by physics itself. Although rarely spoken, it is always there, embedded in every machine, every grid, every fuel system, every attempt to capture and use energy.

And within those limits, something uncomfortable emerges.

Energy is not simply something we can replace at will. Every transformation carries loss. Every system depends on what remains after that loss has been paid. The form energy takes, how dense it is, how easily it can be stored, transported, and deployed, begins to matter far more than the raw numbers suggest.

It is those conditions, not ambition or intent, that determine what a civilisation can sustain.

What follows from this is an uncomfortable reality.

Not all energy is equal. Not in form, not in function, and not in origin.

The primary energy sources that built the modern world carry a unique advantage, one that has nothing to do with human ingenuity and everything to do with time.

Ancient sunlight, absorbed by plants through photosynthesis, was buried, subjected to heat and pressure, and slowly converted into dense hydrocarbons. What we extract today is not current energy flow, but a vast inheritance from the deep past. Energy that arrived daily from the sun has been accumulated and concentrated across geological time into a form that is extraordinarily rich, stable, and usable.

A single barrel of oil contains about 1,700 kilowatt-hours of energy, enough to equal nearly two years of continuous human labour from a healthy adult.

That is what we are drawing down. Not just fuel, but compressed time on a scale that is difficult to grasp.

Nature has already done the work. It has taken diffuse, intermittent solar radiation and turned it into dense, portable, and energy-rich matter. It has effectively performed the long chain of conversions, losses, and compressions on our behalf, delivering a fuel that arrives pre-packaged with high utility and minimal effort required for use.

But there is another dimension to this, one that matters just as much as the energy itself.

Not all energy sources deliver the same return.

In the early days of oil, the energy required to extract it was tiny compared to what it produced. A small investment yielded an enormous surplus. That surplus powered everything else. Infrastructure, industry, healthcare, finance, the entire expansion of modern life.

This is energy return on energy invested (EROEI). In simple terms, how much energy you get back for the energy you spend.

Over time, that return declines. The easiest resources are used first. What remains takes more effort, more energy, more complexity to extract. The system still functions, but with less surplus to distribute.

And it is that surplus, not total energy, that determines what a civilisation can sustain.

Because that concentration process, stretched across millions of years, cannot be repeated at will. It cannot be accelerated, industrialised, or scaled to meet modern demand. We are drawing down a stock, not living off a flow.

Renewables, by contrast, operate in the present. They capture energy as it arrives, in real time, diffuse and intermittent. They do not inherit the compression of time. They must build systems to compensate for it, spreading across land, relying on grids, buffering through storage, and accepting losses at each stage of conversion.

The difference is fundamental. One system is built on accumulated energy, concentrated by time and geology. The other is built on utilising immediate available energy, constrained by variability and conversion.

They are not equivalents. This is where the idea of substitution (unfortunatley) begins to break apart.

Because what is being replaced is not just a fuel, but a one-time geological inheritance. A vast reserve of concentrated energy, formed slowly, used quickly, and impossible to reproduce once depleted.

In a recent article on the Permian Basin, I noted that the largest oil field in the United States was formed over 250 million years ago, before dinosaurs, before the continents had taken their present shape.

The Permian belongs to a different world.

But it is our world that is consuming its stored energy.

The consequences of that difference reach far beyond energy itself.

There is a second, more fundamental issue that sits beneath the discussion of substitution.

Much of the conversation around the energy transition focuses on electricity. Wind, solar, hydro, nuclear. Can we generate enough power to keep the lights on, to run homes, to charge vehicles, to sustain the grid. But electricity is not the core of the system. It is only a part of it.

Globally, electricity accounts for roughly a fifth of total energy use. The remaining majority does not flow neatly through wires. It is embedded in fuels, materials, and processes that electricity alone cannot easily replace.

Oil and gas are not just energy sources. They are feedstocks.

They underpin modern agriculture through fertilisers derived from natural gas. They form the basis of plastics, synthetic fibres, pharmaceuticals, solvents, and countless industrial chemicals. They are woven into the physical fabric of the economy in ways that are often invisible until you try to remove them.

Transport is the most obvious example, but it is far from the only one. Aviation, shipping, heavy industry, mining, construction. These sectors rely on dense, portable fuels that can be deployed directly, without the need for conversion, buffering, or extensive supporting infrastructure.

Electricity can power certain processes more efficiently, and in some areas electrification will expand. But it does not replace the molecular role that hydrocarbons play. You can substitute electrons for combustion in some cases. You cannot easily substitute them for chemistry.

This is where the transition narrative becomes incomplete.

Solving electricity generation does not solve the broader energy system. It addresses a visible layer while leaving the deeper structure largely intact. The world is not powered by electricity alone. It is built from, fed by, and sustained through hydrocarbons.

Remove that foundation, and the challenge is not simply how to generate power.

It is how to replicate an entire material and biological system that has been constructed around it.

And that is a very different problem.

What this leaves us with is an uncomfortable conclusion.

The modern world was not built on energy in the abstract. It was built on a very specific kind of energy. Dense, stored, transportable, and abundant enough to create a surplus far beyond what was needed for survival. That surplus allowed everything else to emerge. Growth, complexity, globalisation, finance, and the assumption that tomorrow would always be larger than today.

That assumption now sits on much weaker ground.

Because our economies and monetary system do not just use energy. They assume it’s expansion.

They assume that production can rise, that consumption can grow, that debts can be repaid out of a larger future. They assume, in ways that are rarely stated explicitly, that the physical foundation will continue to support the financial structure resting on top of it.

But physics does not make promises.

It sets limits.

And when those limits begin to bind, the consequences do not remain confined to energy. They move outward, into the economy, into finance, into the structure of daily life itself.

We are only beginning to feel it.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

Earlier this year, I wrote a three part series tracing the evolution of the US dollar, from Bretton Woods, through the “temporary” suspension of gold convertibility, to the system we operate within today.

That history sits behind one of the most widely repeated claims in modern finance.

At some point in the early 1970s, the story goes, money lost its anchor. When the United States ended convertibility between the dollar and gold, currency became fiat in the purest sense, no longer tied to anything real, no longer constrained by the physical world, and therefore “backed by nothing at all”.

From that moment on, money is said to have become little more than belief, sustained by confidence and enforced by the state.

The idea is repeated so often that it has taken on the quality of truth. It is widely acknowledged but rarely questioned.

But it is not right.

Money did not become unbacked. What changed was the nature of the thing that backed it.

To understand that shift, it helps to step away from finance altogether and look at the system beneath it.

Whether through human labour, machines, or industrial processes, production requires the application of energy to the physical world. Goods are manufactured, food is grown, infrastructure is built, and services are delivered through this continuous conversion of energy into output.

Money sits on top of that process as a claim. It is not valuable in isolation, nor is its value derived from its form. It matters because it represents access to what the economy produces. It is a way of allocating the results of that underlying transformation across society.

For most of history economic activity was limited by the energy available from human and animal labour, supplemented by wind, water, and wood. Growth was slow because the physical inputs required to expand production were themselves limited. Monetary systems reflected that reality. Metal-based currencies such as gold and silver imposed discipline because their supply could not expand faster than the underlying economy for long.

The constraint was physical, and money was forced to operate within it.

The modern era altered that relationship. With the large-scale exploitation of coal, oil, and natural gas, economies gained access to vast quantities of dense, portable energy. For the first time, it became possible to increase output not just incrementally, but at scale by exploring energy reserves on a vast scale and pace of consumption.

Energy use combined with industrial breakthroughs enabled machines to outpace the limitations of labour. Industrial production accelerated in ways that had previously been unimaginable.

This was not just an economic transformation. It was a structural shift in the conditions that made sustained growth possible. For as energy availability expanded, so too did the capacity of the system to grow. And as growth became the defining feature of the modern economy, money no longer needed to be constrained by a fixed commodity. It could instead expand in line with the system it represented.

Fiat money was ideally suited to this environment. An environment defined by abundant, low-cost, high-density energy and reinforced by continuous technological expansion.

Modern fiat currency was never “backed by nothing.” It was backed by something less visible, but more fundamental: the system’s ability to continue growing.

For several decades, that arrangement held.

Energy was abundant and relatively inexpensive, and the surplus generated by its extraction was sufficient to support rising productivity, expanding trade, and increasing complexity across the global economy. Credit could be extended with a reasonable degree of confidence, because the assumption that tomorrow’s economy would be larger than today’s was, for the most part, correct.

Financial systems evolved around that assumption. Debt became not merely a tool, but a central feature of the system itself. Governments borrowed to sustain spending, businesses borrowed to invest and expand, and households borrowed to bring forward consumption. At every level, the same underlying logic prevailed: future growth would justify present claims.

As long as the economy continues to expand, the system can sustain itself. Debt can be rolled forward, interest can be serviced, and asset values can be maintained. But if the rate of expansion begins to slow, or if the physical conditions that enable growth begin to shift, the foundation becomes less secure.

This is where energy re-enters the picture in a more immediate way.

The modern economy still depends on large quantities of it, and despite the language of transition, that dependence remains overwhelmingly tied to fossil fuels. These resources have not disappeared, but the conditions under which they are produced are changing. The most accessible reserves have already been developed. What remains is often more complex, more capital intensive, less energetically dense and harder to extract.

At the same time, demand continues to increase.

The result is not an abrupt shortage, but a gradual tightening of the relationship between energy input and economic output. More effort is required to sustain the same level of activity, and the surplus that once drove expansion becomes harder to maintain.

When that surplus begins to erode, the effects are not confined to the energy sector.

A monetary system built on the assumption of continuous growth begins to encounter strain. The issue is not that money suddenly becomes unbacked, but that the process it represents becomes less predictable. The system continues to behave as though future expansion is assured, even as the conditions that supported that expansion begin to weaken.

Over time, a gap emerges between expectation and reality.

It is within that gap that many of the features of the modern economy begin to make more sense. Rising debt levels, persistent deficits, and increasing reliance on monetary intervention can be understood not as isolated failures, but as attempts to sustain a system that depends on growth in an environment where growth is becoming more difficult to achieve.

The response is not to abandon the system, but to adapt it.

If money represents a claim on future output, and if that output becomes more constrained, then the way those claims are issued, managed, and enforced becomes more important. Financial stability can no longer rely solely on expansion. It must increasingly rely on the management of flows within a more limited system.

Seen in this light, recent developments take on a different character.

The growth of digital payment systems, tokenised assets, and the exploration of central bank digital currencies are not technological innovations to be sold as progress. They represent an effort to build a system that can operate under tighter conditions, transactions can be monitored more closely, monetary stimulus directed and instability managed rather than absorbed.

At the same time, the renewed interest in gold among central banks reflects a parallel concern.

Gold does not generate income, and it does not contribute to growth. But it carries no counterparty risk and does not depend on the future performance of any particular economy. In a system where the reliability of future expansion is less certain, that independence becomes valuable.

These matters taken together are not at all contradictory. They reflect a system adjusting to a change in its underlying conditions. Money was never backed by nothing. It was backed by the capacity of the economy to transform energy into output, and by the expectation that this process would continue to expand.

What follows from this is unlikely to be stated directly, but it is implied in every adjustment now taking place within the system. A monetary framework built for expansion does not survive unchanged in an environment of constraint. It adapts to it.

In the same way fiat was perfectly suited to its environment, so too will the evolution of the monetary system.

When growth is abundant, money can remain permissive. Shocks can be absorbed, inefficiencies tolerated, and excess carried forward. But when the margin for error narrows, the system becomes less forgiving. It begins to prioritise stability over flexibility, management over spontaneity.

A system operating with less surplus cannot afford to be as open as one that operated with more. Flows must be monitored more closely. Liquidity must be directed more deliberately. Instability must be contained earlier, rather than allowed to resolve itself over time.

Money has always reflected the conditions of the world beneath it. When those conditions change, so does the system built upon them. Seen in this light, what is unfolding is not a departure from how money works, but a continuation of it.

The difference now is that the direction of change is no longer toward greater expansion, but toward tighter limits.

A system that once relied on abundance must at some point adapt to constraint. And in doing so, it will favour different qualities: control over openness; precision over flexibility; management over excess.

The monetary system that emerges will not be designed in the abstract. It will be shaped by the environment it must operate within.

And that environment is changing.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

For years the Permian Basin has served as the exhibit piece for those insisting that depletion fears are overwrought.

In the arid expanse of West Texas and southeastern New Mexico, the Earth is said to hold one of the largest concentrations of hydrocarbons ever discovered, a geological inheritance laid down in the Permian period, 250 million years ago, when the continents were fused into the single global mass of Pangaea.

The sequence of ancient seas, evaporite beds, and sedimentary layers produced reservoirs on a colossal scale; by some estimates, as much as 150 billion barrels of technically recoverable oil lie within the rock. On paper that makes the Permian a supergiant, one of the largest oil fields in human history. And if one views energy as a matter of sheer volume, it appears to validate the comforting belief that the world is not, in fact, running out of oil.

But size isn’t everything.

The oil age was never defined by the amount of hydrocarbon locked in stone; it was defined by the surplus energy those hydrocarbons delivered once extracted. What made the twentieth century possible was not the existence of oil, but the ease with which it could be coaxed from the earth and the generosity with which the early fields gave up their contents. A conventional supergiant was a pressurised gift: drill a hole, and the wellhead roared. The energy return on energy invested was vast and the surplus was civilisation’s dividend.

The Permian belongs to a different world. A time before dinosaurs roamed the earth. It is immense geologically, but energetically it is thin. The oil is not pooled in cavernous porous reservoirs; it is trapped in rock so tight it barely flows, imprisoned within microscopic pores that behave more like a ceramic than a sponge. To extract this oil, drillers must not only reach the rock, they must break it open with violence: drilling horizontal wells for kilometres through brittle layers, then shattering those layers with enormous volumes of pressurised water, chemicals, and sand. The shale well is not a gentle siphon. It is a controlled rupture. And the energetic cost of that rupture is enormous.

So while the Permian is vast in place, it is poor in surplus. The EROEI, the return on the energy spent drilling, fracking, pumping, transporting, and processing, hovers at perhaps two or three units of energy returned for each invested. In the richest pockets, it may reach four or five, but never approaches the levels that built the modern world. The Permian’s size qualifies it as a supergiant, but its surplus does not. It is a supergiant in geology only. In thermodynamics it is a marginal, low-grade substitute for what has already been lost.

And while a conventional well might decline two or three percent per year, a shale well dies young. Its production surges briefly, then collapses without mercy: sixty to seventy percent gone in the first twelve months, eighty percent gone within three years, effectively depleted within a handful of years. To maintain production, companies must drill incessantly, thousands of wells every year, simply to stay level. The moment drilling slows, output plummets. This is the treadmill at the heart of the shale revolution: movement without progress, growth achieved only through acceleration. In the early 2020 pandemic year, when drilling paused, U.S. shale production plunged almost instantly. The supposed “abundance” evaporated at the first hint of restraint.

There is a deeper, quieter problem beneath even this. The best rock has already been consumed. Every shale basin contains a finite fraction of “Tier 1” geology, the sweetest, thickest, most permeable zones. These were drilled first, because they offered the only hope of profit. Now, well over half of these zones are already saturated with wells. New drilling increasingly reaches for “child wells” near depleted parents, cannibalising reservoir pressure and lowering yields across the board. The industry has responded by extending laterals, increasing frac stages, multiplying sand loads, not to improve the geology, but to bully more oil from weakening formations. These techniques delay the end of the story but do not change it. When one must strain this hard to maintain output, it is a sign not of abundance, but of exhaustion.

And then there is the matter of money. Shale did not triumph through its own economic strength. It triumphed because the monetary environment where banks poured oceans of cheap credit into any sector promising yield. Zero interest rates made drilling practically free. Investors demanded growth at any cost and were willing to subsidise years of negative cash flow to achieve it. Nearly the entire shale industry survived the 2010–2020 decade without generating cumulative positive free cash flow. It drilled on borrowed money, borrowed futures, and borrowed patience. The Permian rose not because its energy was cheap, but because its financing was. The shale boom was a monetary phenomenon masquerading as an energy renaissance.

Critics who point to the raw reserve numbers – the 150 billion barrels “left in the ground” – misunderstand fundamentally what oil means to a civilisation. Life is not powered by barrels in rock; it is powered by the usable surplus civilisation receives after the costs are paid. A barrel that costs half a barrel to obtain is radically different from a barrel that costs one percent of a barrel. The world was built on the latter. We are now surviving on the former.

The Permian is not proof that peak oil is a myth. It is the confirmation of peak oil: the last great repository of hydrocarbons that can be forced into production with enough capital, diesel, sand, pressure, and debt. And this is the real irony. Critics imagine that shale’s scale refutes the idea of depletion. But shale exists because depletion is already far advanced. If the world still possessed a pipeline of conventional supergiants, no one would bother pulverising stone to release trapped hydrocarbons at enormous energetic cost. No society turns to such difficult, fragile, short-lived energy unless the easy energy is gone.

The Permian, then, should be read not as a triumph but as an epitaph. It is the last large basin we will ever discover of this scale, and it offers almost none of the surplus that previous giants delivered. It keeps global production figures aloft, but only through frantic drilling and the ongoing sacrifice of capital. The plateau it generates is an illusion, a level horizon created by thousands of tiny peaks and near-immediate declines. Beneath the smooth line lies chaos.

This is the real shape of the age we inhabit. Decline rarely announces itself with drama. It disguises itself as continuity. It allows the charts to rise even as the energy and capital required to sustain them silently multiplies. By the time the decline becomes visible, the structure beneath has already hollowed out.

The Permian’s vast reserves are not a promise of future abundance. They are the geological residue of past abundance, scraped together and spent in a final attempt to prolong a system that cannot continue. It is a supergiant in name only, a last flare of the fossil inheritance that made the modern world. And as its sweet spots fade and its drilling intensifies, the truth becomes unavoidable: we are not entering a new era of energy plenty. We are living through the delayed confirmation that the old one has already passed.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

The architecture of the next monetary system is being built in plain sight, but described in language so technical that almost no one outside the policy world hears what it means. The language is neutral, bureaucratic, bloodless. Yet in plain terms, the world’s monetary system is quietly being rebuilt on digital rails.

What regulators call “modernising financial infrastructure” is, in practice, the construction of a fully programmable environment in which every monetary unit and every financial asset can (in the future) be verified, traced, and conditioned at the point of transaction. It is an ecosystem designed not only to record activity but to enforce rules automatically, the merger of compliance and settlement.

The Bank for International Settlements now frames this transition as the emergence of a “unified ledger”, a single, programmable layer that hosts tokenised forms of central-bank reserves, commercial-bank money, and government bonds. In its 2024 report to the G20, the BIS defines this structure as a “token arrangement”, the combination of infrastructure, legal frameworks, and governance mechanisms that allow the recording, transfer, and settlement of tokenised assets and money across multiple institutions and jurisdictions.

In other words, what was once described as a set of discrete systems is now envisioned as a single programmable architecture, a neutral-sounding phrase for what is, in effect, the operational core of the next monetary regime.

This design is evolutionary rather than revolutionary. It preserves the two-tier monetary structure, keeping private banks between citizens and the central bank, while migrating all final settlement onto digital rails. In this model, the central bank provides the tokenised reserves that anchor the system; commercial banks issue tokenised deposits that interface with the public; and every transfer between them is cleared on a shared ledger under a single set of coded rules.

For policymakers, the rationale is efficiency. Tokenisation eliminates reconciliation delays, reduces operational risk, and allows transactions to settle instantly in central-bank money. Yet beneath the rhetoric of efficiency lies the deeper shift: once money and regulation coexist on the same programmable substrate, policy becomes protocol. Rules that once required legislation or discretion can now be embedded directly into settlement logic.

Such automation becomes essential as the energetic margin for error narrows. Manual oversight is too slow, too costly, and too energy-intensive for systems running on declining surplus. Compliance must therefore be automated, not because it is efficient, but because the system no longer has the spare capacity to operate otherwise.

This infrastructure also redefines the meaning of liquidity and oversight. In a tokenised system, every asset is visible to the network; every movement can be validated in real time against policy parameters. Central banks and regulators gain continuous situational awareness of flows, exposures, and counterparties. Supervision shifts from retrospective to immediate. Monetary and prudential policy can be executed through automatic adjustments in code, a form of algorithmic steering. The institutions remain, but their agency migrates into the architecture.

The BIS describes this consolidation with remarkable clarity. In its 2024 report to the G20, it notes that “tokenised money and assets can coexist on the same platform, enabling atomic settlement and new forms of automation that reduce counterparty risk and eliminate the need for reconciliation.” In policy language, this is efficiency; in practice, it is fusion, the absorption of every financial function into a single programmable substrate where nothing moves outside the network.

This new architecture is not speculative; it is already being assembled.

To the public, nothing in this appears dramatic. People will still see their commercial bank, their digital wallet, their payment app. But every transaction will clear through a system that already contains the logic of compliance. In this sense, the infrastructure of control will arrive disguised as infrastructure for safety. No announcement of a retail CBDC is required; the function is achieved invisibly through tokenised deposits and wholesale settlement.

Internationally, this migration is being coordinated by the same network of institutions that manage the global financial order: the BIS, IMF, and Financial Stability Board. Their joint roadmaps now reference interlinked tokenised systems, cross-border pilot programs, and common settlement assets for instant payments. These initiatives, Project Rosalind in London, Project Guardian in Singapore, Project Agorá in New York, are laboratories for the unified ledger in practice. Each experiment digitises a piece of the two-tier system: the reserve, the deposit, or the instrument that connects them. Together they form the scaffolding of the next monetary regime.

Compliance, in this context, is no longer an external requirement; it is the design principle of the system itself. By embedding verification into the ledger, authorities achieve what decades of regulation could not: complete visibility without overt coercion. Trust is engineered. Transparency becomes total, but only in one direction. And once every transaction exists inside that programmable space, the distinction between financial stability and behavioural governance becomes a matter of policy setting.

This is what is meant by the tokenised infrastructure of compliance: a monetary system that regulates itself in real time, guided by rules written not in law but in code, and by institutions that govern not through edict, but through the architecture itself.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

During the First World War, the British state summoned its young men with a simple command. A moustached Lord Kitchener pointed outward from posters and billboards, his gaze fixed on the individual, his message unambiguous:

Your country needs you.

That sentence captured the logic of an age. The individual mattered. Their labour, their loyalty, and even their sacrifice were essential to the survival of the system itself.

For most of the modern era, that assumption has held. The system needed people. It needed their work, their consumption, and their participation to function and to grow.

Now, that relationship is beginning to change.

The shift is not ideological. It is structural. The conditions that once made the individual economically indispensable are weakening, and with them, the role the individual once played.

What follows is a harder truth. Not speculative, but increasingly visible.

Your country does not need you anymore.

For most of the fossil-fuel age, the average Westerner was valued for two reasons.

First, as a voter. Democratic participation conferred legitimacy. Citizens were courted, persuaded, mobilised. The ritual of the ballot mattered not because it changed everything, but because it sustained the belief that power ultimately rested with the public.

Second, and far more importantly, as a consumer and taxpayer. Spending drove growth. Growth stabilised debt. Debt sustained the system. Consumption was not merely personal choice; it was economic function. Advertising saturated every surface because buying things was structurally essential. To consume was to serve.

The bargain was never spoken aloud, but it was widely understood. Freedom in exchange for participation in growth. Autonomy, as long as it remained profitable. Rights, cushioned by surplus.

As long as energy was abundant, this arrangement worked. The citizen-consumer was valuable, and therefore politically protected. Dissent could be tolerated. Inefficiency could be absorbed. Nonconformity could be reframed as creativity. Freedom felt like a moral right when it was, in truth, an energetic luxury.

But when surplus energy disappears, the logic reverses. Growth ceases to be the objective. Stability becomes the priority. And in a system organised around managed scarcity, mass consumption is no longer an asset. It is a liability. The high-consuming individual becomes a problem to be solved, not a contributor to be encouraged. Their freedom to travel, eat, heat, or spend without limit is no longer compatible with system coherence. What once legitimised the order now threatens it.

The psychology is familiar. Anyone who has passed through airport security has experienced it. On one side of the checkpoint, you are processed, scanned, stripped of rights, treated as a risk until proven otherwise. On the other side, you are welcomed back as a valued customer, ushered into comfort and consumption. The system’s view of you has not changed. Only the phase of the process has.

As scarcity deepens, more of life moves permanently to the first side of the checkpoint.

This is the unspoken calculation: if people can no longer drive growth, why preserve the freedoms designed for a growth economy? Political rights that once stabilised the system become potential sources of disruption. You cannot vote scarcity away. And once control is embedded in infrastructure, you cannot vote it out at all. Democracy does not die when elections stop. It withers when votes stop mattering.

The democratic bargain of the industrial era rested on surplus. Governments could promise rising prosperity in exchange for participation. As long as growth delivered higher wages, expanding consumption, and widening opportunity, the ballot retained weight. But when surplus disappears, the link between political choice and material outcome breaks. Elections continue. Campaigns persist. Institutions remain intact in form. Yet real decision-making migrates elsewhere, into energy constraints, debt dynamics, and digital systems beyond electoral reach.

This is the slow death of the citizen, and with it, the quiet hollowing of democracy itself. The individual is no longer a participant whose consent matters. They are reclassified as an authorised user whose access can be conditioned or withdrawn. Rights cease to be universal guarantees and become situational permissions. Participation is allowed, but only within parameters defined elsewhere.

The shift might be subtle. Limits are framed as protections. Restrictions are sold as safeguards. But the trajectory is the same. The citizen becomes an object of administration, their life defined not by what they may do, but by what the system allows them to do.

History offers warnings. When the late Roman Empire’s expansion stalled, citizens once valued as engines of growth and military power were reduced to taxable subjects governed through bureaucracy rather than consent. In the twentieth century, wartime democracies placed entire populations under rationing and central command, with freedoms returning only partially afterward. During the oil shocks of the 1970s, political systems hardened rapidly as stability displaced liberty.

The pattern is consistent. When surplus vanishes, political rights erode. What distinguishes the coming transition from its predecessors is not intent, but capability. Earlier systems relied on ration books, tax collectors, and visible enforcement. Today’s architecture is digital, instantaneous, and adaptive. Scarcity management embedded in code does not announce itself as authority. It presents itself as normality. By the time limits are felt, they no longer appear imposed. They appear natural.

Once this reclassification is complete, it does not reverse on its own. The citizen does not vanish in a single moment. They fade into a managed profile, a bundle of permissions, scores, and conditional access rights. Democracy persists as ritual, while governance migrates into systems that no longer require belief, only compliance.

This is not the collapse of politics. It is its automation. And in that automation, the individual is no longer needed as a source of legitimacy or growth. They are needed as a unit to be regulated. The age of the citizen ends not with violence or fascist decree, but with a quiet, growing irrelevance.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

Most people assume the global monetary system was carefully designed.

It wasn’t.

What we call the modern dollar system is less like a cathedral of finance and more like emergency scaffolding that was never removed after the building crisis passed. It was erected quickly, under pressure, in the early 1970s when the old system collapsed. The assumption at the time was that something more permanent would eventually replace it.

Instead, the scaffolding became the structure.

For over fifty years the world has operated inside a monetary system that was never truly planned, never formally agreed upon, and never intended to serve as the permanent foundation of the global economy.

The reason it survived so long is not because it was stable. It survived because the world kept growing.

As long as the global economy expanded fast enough, the contradictions inside the system could remain hidden. Debt grew, but so did GDP. Governments borrowed, but rising production made the promises seem manageable. Asset prices inflated, but the tide of expansion lifted almost everything alongside them.

Growth was the oxygen that kept the fiat heart beating alive. And for decades, the oxygen supply seemed endless.

Whenever someone suggests that the fiat dollar system might eventually fail, the reaction is often immediate and dismissive.

The argument usually goes something like this: the dollar dominates global trade, sits at the centre of financial markets, and is backed by the most powerful military in the world. It has survived wars, crises, and recessions. Therefore it will continue indefinitely.

But this debate usually begins in the wrong place. It assumes that the current system is in place because it works, because it was designed to be effective.

The real question is not whether the dollar is strong today. The real question is whether the system that governs the global monetary order was ever intended to exist in its current form.

The answer is no.

The modern fiat system was not designed as a permanent architecture for the world economy. It was an improvised response to a crisis half a century ago. What emerged after that crisis was not a carefully constructed monetary framework but a kind of financial stop gap that persisted far longer than anyone expected.

And the reason it persisted has less to do with monetary genius than with something far more fundamental.

Growth: The Hidden Condition of Fiat

Fiat money has a peculiar characteristic. It only works comfortably in a world that is expanding.

The reason lies in the way modern money is created. In today’s system, new money largely enters the economy through credit. Money is largely born as debt.

Debt carries interest, and interest implies something simple: the future must be larger than the present. There must be more economic activity tomorrow to service the obligations created today.

This means that a debt-based monetary system quietly assumes continuous expansion. Growth is not merely beneficial; it is structurally necessary.

For several decades after the Second World War, that condition appeared to hold.

Cheap energy allowed production and consumption to scale at extraordinary speed. The world economy felt like it was on a permanently rising trajectory.

Under those conditions, fiat money worked remarkably well.

Debt expanded, but so did the economy. Governments borrowed, but tax revenues rose alongside GDP. Credit creation accelerated, yet the underlying system continued to grow fast enough to absorb it.

What looked like monetary stability was in fact something more fragile: a financial structure balanced on the assumption of perpetual expansion.

The Accidental System

This context matters because the modern dollar system did not emerge from some grand design.

The monetary framework that exists today was never formally negotiated the way earlier systems were. It simply evolved after the collapse of the post-war order in the early 1970s.

Once the dollar was no longer tied to gold, the world entered an entirely new era of purely fiat money. Exchange rates floated, central banks gained new powers, and financial markets expanded dramatically.

Yet no single moment defined the rules of the new system.nThere was no new Bretton Woods conference. No globally agreed monetary constitution.

Instead, the dollar remained dominant largely because it already occupied the centre of global finance. Oil continued to be priced in dollars. U.S. Treasury markets became the primary reserve asset for central banks. Global trade increasingly settled transactions in dollars simply because the infrastructure was already there.

In other words, the system persisted because it was convenient. Not because it was intentionally designed to be permanent.

Why It Lasted

Given its improvised origins, the more interesting question is not why the system might eventually fail. The interesting question is why it lasted this long.

The answer returns to the same underlying force: expansion.

For half a century the global economy experienced an extraordinary combination of favourable conditions. Industrial capacity expanded. Globalisation opened vast new labour pools. Credit markets deepened. Technology accelerated productivity.

Most importantly, the world continued to benefit from abundant energy resources that allowed economic activity to scale far beyond anything seen in previous centuries.

In such an environment, the weaknesses of fiat money could remain largely hidden.

Debt grew rapidly, but the economy grew as well. Asset prices inflated, but rising incomes and expanding markets masked the imbalance. Governments accumulated deficits, yet financial markets continued to absorb them.

The system functioned because growth made its contradictions manageable.

But that condition is beginning to change.

The Limits of Expansion

In recent decades, the signs of strain have become increasingly visible.

Global debt has expanded far faster than the underlying economy. Government deficits have become structural rather than temporary. Central banks have been forced to intervene repeatedly to stabilise financial markets.

Each major crisis has required larger interventions than the last.

The financial crisis of 2008 triggered unprecedented monetary stimulus. The pandemic years saw deficit spending spiral. Today, many governments face debt levels that would have been considered unimaginable a generation ago.

These developments are often interpreted as policy mistakes. But they may also reflect something deeper: the gradual slowing of the growth engine that once sustained the system.

If the world economy cannot expand indefinitely, then a monetary architecture built on the assumption of perpetual expansion becomes increasingly unstable.

The problem is not the dollar itself. In a world of infinite energy and growth the dollar may be able to exist indefinitely.

The problem is the system beneath it.

The Next Monetary Moment

History suggests that global monetary arrangements eventually change when their underlying assumptions break down.

The gold standard ended when it could no longer accommodate modern financial demands.

The Bretton Woods system ended when the dollar could no longer maintain gold convertibility.

The current fiat system emerged from that crisis, but it was never intended to be the final stage of monetary evolution.

What makes the present moment different is that the next system is unlikely to arise accidentally. Unlike the early 1970s, policymakers today possess technological tools that allow money itself to be redesigned.

Central Bank Digital Currencies are often described as simply the digital version of cash. In reality they represent something far more significant.

They allow money to become programmable.

Transactions can be recorded instantly. Monetary policy can be transmitted directly to individuals. Spending behaviour can be influenced or restricted through the structure of the currency itself.

In short, the monetary system becomes a digital infrastructure.

Designed for the Age

Every major monetary system reflects the technological and political conditions of its time.

The gold standard suited an era of metal money and limited financial complexity.

Bretton Woods suited the industrial world of the mid-twentieth century.

The next system will likely reflect the digital infrastructure of the twenty-first.

If such a system emerges, it will not resemble the improvised architecture that has governed the past fifty years.

It will be deliberate. Designed. Integrated directly into the technological networks that now organise finance, trade, and information.

The Real Debate

The debate about the future of the dollar often becomes trapped in arguments about geopolitics or currency competition.

Will China challenge the dollar?

Will another reserve currency emerge?

But these questions may be missing the deeper transformation underway.

The real issue may not be which country issues the next dominant currency but whether the nature of money itself is about to change.

The current system survived because it was able to ride the momentum of an expanding world economy. Growth concealed the instability built into a debt-based monetary order. As long as tomorrow looked larger than today, the promises embedded in the system appeared credible.

But when growth slows, promises begin to look like liabilities. And when the underlying engine of expansion weakens, the architecture built on top of it begins to tremble.

Monetary history suggests that moments like this rarely end with the simple continuation of the old system. They end with the creation of a new one.

The system that replaced Bretton Woods in 1971 was improvised. It emerged from crisis rather than design.

The next monetary order is unlikely to be so accidental.

It will almost certainly be built deliberately, using the technological tools that now exist to redesign money itself.

Central bank digital currencies are the clearest signal of this shift. They allow money to move from being a neutral medium of exchange to something far more powerful: a programmable layer within the economic system.

In such a world, money is no longer simply spent. It is permitted.

And if the last fifty years were defined by a monetary system sustained by the promise of endless expansion, the system that follows may be designed for a very different era.

An era in which growth is no longer assumed. Where the management of scarcity becomes the central task of economic policy.

In that world, the scaffolding of the old system will finally be dismantled.

Not because it failed due to a single event but because the age that allowed it to function is quietly but inevitably coming to an end.

The system that replaces it will not simply facilitate the economy.

It will help govern it.

Central Bank Digital Currencies are the monetary system being prepared for the world ahead. The perfect money for a civilisation that can no longer sustain the illusion of endless growth.

Whether introduced quietly before a crisis or imposed suddenly after one, CBDCs are not the product of progress.

They are the architecture of a world learning to manage limits.

This post is part of a series of essays linked to a wider macro thesis: The Long Convergence.

The modern environmental conversation has become monocultural. Carbon has become the single metric through which ecological virtue is judged. Meanwhile a series of immediate and measurable environmental crises receive comparatively little attention.

Anthropogenic climate change is real, measurable, and increasingly visible. But while the focus is on carbon and a net zero agenda we live in an age where numerous ecological crisis are unfolding, causing devastating and potentially irreversible damage to our environment and our very lives. Few seem to be worthy of the global policy attention that we give to carbon at the expense of all else:

Biodiversity Loss / Mass Extinction

Scientists call this the Sixth Mass Extinction: species are vanishing at up to 1000 times the natural background rate. WWF’s Living Planet Report 2022: global wildlife populations down 69% since 1970. IUCN Red List noted 42,000 species currently threatened with extinction (out of ~150,000 assessed). IPBES (2019): warns that ~1 million species are at risk of extinction within decades unless trends are reversed.

The cause of this mass extinction? It’s human action, whether through deforestation, urban sprawl, agriculture, pesticides, overfishing, bushmeat, hunting, pollution, invasive species, pathogens, and yes, climate change is also playing a part - whatever the cause, we have been the source of this extinction.

Humanity has accelerated extinction from a background trickle of a few species per year to a flood of hundreds or thousands vanishing annually, placing us firmly in the opening chapters of a human-driven mass extinction. It is shameful. And consistently underreported.

Insect Decline (Insectageddon)

Insects are collapsing worldwide. Studies suggest ~40% of insect species in decline, with some regions losing 70–80% of biomass in just a few decades. Pollination (1/3 of human food relies on insects), soil fertility, decomposition, food chain collapse.

A 2017 study in Germany found a 75% decline in flying insect biomass over 27 years in protected nature reserves. Global meta-analyses suggest ~40% of insect species are in decline, with many facing extinction within decades. Some regions (e.g. parts of Puerto Rico, Central Europe) report 70–80% biomass losses over a few decades.

While politicians may blame this on climate change the truth is that pesticides (especially neonicotinoids, systemic insecticides that persist in soil and water), Habitat loss (intensive monoculture farming, urban sprawl) and Pollution (nitrogen fertilizers, industrial chemicals) are the culprits.

We are destroying a cornerstone of what makes life on earth possible - the pollinators

Deforestation & Land-Use Change

We lose 10 million hectares of forest per year due to cattle ranching, palm oil, soy, logging which knead to direct biodiversity collapse, disruption of rainfall cycles, soil erosion and displacement of animals and people alike. Ares of the Amazon, Congo Basin, and SE Asia are hotspots. As we tear up diverse dense forests for intense farming purposes, not only do we do direct damage to the environment (the actual environment) we reuse the capacity of these habitats to be stores of carbon (50% of all annual Co2 is stored by the earth via land and ocean via natural cycles). These carbon ‘sinks’ are invaluable.

Soil Degradation & Desertification

Over one thirds of topsoils degraded; at current rates, 90% could be degraded by 2050. The cause? over-farming via intense monocrops, chemical fertilisers to subsidise the soil, erosion, deforestation. The potential consequence? falling crop yields, food insecurity, desert expansion. This alone has the threat to impact global agriculture and civilisation - if history has taught us anything it’s that hungry people revolt when they starve.

Freshwater Depletion & Pollution

Over 2 billion people live under water stress. Aquifers (e.g., Ogallala in the U.S., North China Plain, India’s groundwater) are being drained unsustainably. Rivers like the Colorado, Indus, and Yellow River often no longer reach the sea. In many parts if Asia, river flow not with fresh water but with millions of plastic bottles and containers. In the UK, water companies, rather than invest in treatment capacity simply dump raw sewage into our rivers, damaging our waterways, killing wildlife and creating a putrid environment in our lakes, all the while rewarding their shareholders with dividends.

Ocean Degradation

Overfishing: ~90% of global fisheries fully exploited or overexploited. Dead zones caused by nutrient runoff creates hypoxic zones (Gulf of Mexico, Baltic). Oceans regulate wind, rain, climate, food, and oxygen supply (phytoplankton). They cover two thirds of the planets surface and have been decimated by our direct behaviour for decades. In the U.K. the mighty Atlantic Salmon, once a common immigrant to our rivers has all but disappeared from the scene, a victim of ecological damage from a variety of sources. Reclassified in 2023 to “Endangered,” with losses of 80% in just a few years.

Plastic & Chemical Pollution

Over 350 million tonnes produced annually; microplastics now in blood, lungs, placenta. It is estimated that 11 million tonnes/year enter oceans, projected to triple by 2040. This accumulates with saddening consequences. The Great Pacific Garbage Patch (GPGP) is one of the starkest symbols of ecological collapse and a perfect example of a crisis that is visually undeniable, but politically sidelined.

A massive accumulation of floating plastic debris in the North Pacific Ocean, trapped by the North Pacific Subtropical Gyre (a system of currents between California and Japan). The scale is truly horrific. Estimates range from 1.6 million km² (twice the size of Texas, or three times the size of France) but perhaps up to 3x that, depending on how you define its edges. It contains 1.8 trillion pieces of debris, made up largely of plastics and is expanding by millions of tonnes a year. These plastics photodegrade into smaller particles but don’t fully biodegrade meaning the patch is a long-term raft of persistent toxins.

The Great Pacific Garbage Patch is the shadow of our throwaway culture, an oceanic monument to a civilisation that confuses consumption with progress. Unlike carbon, it floats largely outside the machinery of global policy, growing like an aquatic tumour year on year.

Air Pollution (non-CO₂)

Perhaps the most deadly of them all from a human perspective - air pollution. Fine Particulates, tiny particles from diesel, biomass, and industrial processes penetrate deep into the lungs and bloodstream. Nitrogen oxides from vehicles and industry contribute to smog and respiratory disease. Sulfur dioxide, mainly from coal, causes acid rain and lung damage. Ground-level ozone formed when and volatile organic compounds (VOCs) react in sunlight; harmful to lungs and crops. Carbon monoxide (CO): from incomplete combustion; reduces oxygen delivery in the body. Lead & heavy metals: from industry and legacy fuels; cause neurological damage.

The World Health Organisation estimates 7 million premature deaths annually from air pollution. Stroke, lung cancer, heart disease, asthma, and chronic respiratory illnesses are strongly linked. In children major developmental effects (lowered IQ, asthma onset). Within the environment acid rain from toxic air damages forests, soils, and freshwater ecosystems.

Air pollution kills more people each year than war and famine. It could be solved with existing technology and regulation, yet it receives a fraction of the attention given to man made climate change.

Why this Matters.

The above ecological issues all pose an existential crisis to out our planet and all of them are here now, not arriving in the future, all are observable and measurable and worsening by the day, causing unthinkable damage and death. Yet of all these crises, only one would rise to dominate global policy: carbon.

As we move into the apex of the long convergence, carbon becomes the ultimate control variable that will underpin the morality of a new monetary and societal order.
