Recent August ISM Services PMI strength at 55.4, exceeding forecasts amid business activity at 61.7 and new orders at 60.9, has anchored trader expectations for September near the mid-54 range despite the 12-month average near 53.7. Persistent price pressures, with the index climbing to 72.6 on tariff and Middle East supply-chain effects, alongside employment contraction at 47.8, introduce downside risks that could moderate readings. Positive summer seasonality and broad demand gains support the potential for sustained expansion above 55, while cautious hiring and elevated input costs create scope for outcomes clustering between 53 and 56. The early October release will test whether momentum holds or reverts amid these crosscurrents.
