Recent September ISM Services PMI data at 54.9, slightly below consensus, highlighted moderating business activity and new orders alongside a rebound in employment to 50.1 and a surge in the prices-paid index to 74—the highest since mid-2022—driven by tariffs, fuel costs, and supply-chain strains. These factors, combined with elevated backlogs and resilient domestic demand, create a narrow band of likely outcomes near 54–56 for October, as traders weigh sustained expansion signals against risks of further cooling or sticky inflation. Market-implied odds remain closely contested because the series has fluctuated modestly in this range for months, with the November 4 release sensitive to any shifts in consumer spending, energy prices, or labor trends ahead of year-end policy decisions.
