FX.co ★ U.S. Services Momentum Eases Slightly as ISM Non-Manufacturing PMI Dips to 54.9 in September

The U.S. services sector showed a modest loss of momentum in September, as the ISM Non-Manufacturing Purchasing Managers’ Index (PMI) edged down to 54.9 from 55.4 in August 2026. Despite the slight decline, the latest reading remains comfortably above the 50-point threshold that separates expansion from contraction, signaling that activity in the services-driven U.S. economy continues to grow.

The updated data, released on 5 October 2026, suggest that while the pace of expansion has cooled marginally, underlying demand in services such as finance, healthcare, technology, and hospitality remains resilient. The small pullback from August’s level may indicate that businesses are becoming slightly more cautious, but not enough to tip the sector out of its expansionary phase.

For markets and policymakers, the September reading reinforces the narrative of a still-expanding U.S. services economy, albeit at a slightly slower clip. With the PMI holding above 54, the data will likely be interpreted as a sign of continued economic growth, while also giving room to assess how sustained this pace can be in the face of evolving financial conditions and broader macroeconomic uncertainties.
