Recent August core CPI rose 0.3% month-over-month—hotter than the 0.2% consensus—driven by firmer services prices including shelter, airline fares, and education costs, amid elevated energy pressures from geopolitical tensions. This print, released just days before the September FOMC meeting, has lifted market-implied odds of a 25-basis-point rate hike while underscoring persistent core momentum after softer July readings. With September data still weeks from release, trader sentiment clusters tightly between 0.2% and 0.3% outcomes, reflecting uncertainty over whether the August acceleration signals a durable uptick or seasonal volatility around goods deflation and shelter trends. Key near-term catalysts include incoming labor-market data and any further shifts in Treasury yields or Fed communications that could recalibrate inflation expectations.
