Recent softening in U.S. services activity has positioned the 53.0–53.9 range as the leading outcome for the October 2026 ISM Services PMI, with 35% implied probability. The September reading of 54.9 marked a second consecutive decline from August’s 55.4, missing consensus and confirming momentum loss in business activity and new orders. Elevated price pressures, with the prices-paid index reaching 74.0—the highest since 2022—alongside supply-chain strains from tariffs and fuel costs, reinforce trader expectations for further moderation ahead of the November 4 release. Regional surveys showing October weakness add to the data-driven consensus, though resilient domestic demand could still support readings near 54.0–54.9.
