The August 2026 ISM Services PMI release at 55.4, exceeding consensus expectations of 54.3 and July’s 54.1 reading, anchors the near-certain 100% market-implied probability in the 55.0–55.9 bucket. Services activity expanded for the 26th straight month, supported by faster gains in business activity (61.7) and new orders (60.9), alongside rising inventories and backlogs, even as employment contracted further and the prices index hit a multi-year high of 72.6 amid tariff and energy cost pressures. This outcome aligns with the broader post-July stabilization in services data and reinforces the market’s skin-in-the-game consensus on moderate expansion. A material revision to the headline figure or an unexpected contraction in new orders would be the primary scenarios capable of shifting resolution.
