• US ISM Services PMI eases to 54.9 in September from 55.4 in August, missing expectations of 55.7.
  • Reading remains well above the 50 expansion threshold, indicating continued growth in the largest part of the US economy.
  • Modest slowdown reflects resilient demand but may temper expectations for further Fed tightening.

Services Activity Remains in Expansion Territory

The US services sector continued to expand in September, albeit at a slightly slower pace, according to the latest Institute for Supply Management (ISM) report. The ISM Services PMI registered 54.9, down from 55.4 in August and below pre-release market expectations of around 55.7. The reading, however, remains comfortably above the 50 level that separates expansion from contraction, underscoring the resilience of the service-oriented economy.

The modest decline suggests a cooling in momentum rather than a deterioration. “The September print still points to solid growth in services, which is reassuring, but the softer-than-expected figure may give the Federal Reserve a bit more breathing room,” said an economist familiar with the survey. The ISM’s survey covers industries such as health care, finance, professional services, and hospitality, which together account for the bulk of US output and employment.

Underlying Details Show Mixed Signals

While the headline index eased, the details of the report revealed a complex picture. The business activity index, which measures current output, remained at a robust level, though down from August’s 61.7. New orders also stayed well above 50, indicating that demand remains durable. However, the employment subindex continued to contract for a second consecutive month, signaling that hiring in the services sector remains cautious. The prices-paid measure, which tracks input costs, remained elevated, highlighting persistent inflationary pressures.

The combination of resilient demand, weak hiring, and high prices suggests that the service sector is still grappling with supply-chain and labor challenges. “Firms are still busy, but they’re not rushing to add workers, and they’re still paying more for inputs,” noted a supply chain executive. This dynamic could complicate the Fed’s efforts to bring inflation back to its 2% target without stifling growth.

Market Implications and Policy Outlook

Financial markets reacted modestly to the data, with Treasury yields edging lower and the dollar softening against major currencies. The cooler-than-expected reading may reduce the urgency for additional Fed rate hikes, especially if upcoming inflation data show signs of easing. However, with the prices-paid index still high, policymakers are unlikely to declare victory on inflation just yet.

“The report reinforces the narrative of slower but still expanding services activity,” said a strategist at a major investment bank. “It’s a fine balance for the Fed: they want to see demand cool to tame inflation, but not so much that it tips the economy into recession.”

The ISM services PMI is closely watched as a leading indicator of economic health. A reading above 49 over time is generally consistent with overall economic growth. The September report suggests that the US economy remains on firm footing, though the loss of momentum bears watching in the coming months.

Key Subindices to Monitor

  • New orders: A sustained reading above 50 would signal continued demand strength.
  • Employment: A move back above 50 would ease concerns about labor market softness.
  • Prices paid: A decline would support the disinflation narrative and give the Fed more flexibility.

No Company-Specific Impact

The ISM report is a broad survey of purchasing and supply executives across industries and does not pertain to any single company. It is published by the Institute for Supply Management, a nonprofit professional association. The data is based on responses from executives in industries that contribute significantly to US GDP.

An earlier version of this article incorrectly stated the August services PMI reading. It was 55.4, not 54.9. We regret the error.
