Recent September ISM Services PMI data at 54.9, slightly below consensus near 55.0 and down from August’s 55.4, anchors trader focus for the October reading amid ongoing services-sector expansion. Business activity and new orders moderated while employment ticked above 50 and prices paid climbed to 74.0—the highest since mid-2022—reflecting sustained cost pressures from tariffs, fuel, and supply-chain constraints. These dynamics keep the distribution centered on the low-to-mid 50s with meaningful probability mass around 57, as markets weigh resilient demand against potential further cooling in activity or persistent inflation signals. Key near-term catalysts include October employment and inflation releases plus any shifts in Fed communications on rate expectations.
