• The S&P Global US Composite PMI rose to 54.8 in October, up from 53.9 in September, signaling the fastest pace of private sector expansion in recent months.
  • Service sector growth surged to 55.2, significantly outpacing the 53.5 estimate, while manufacturing PMI reached 52.2 versus a 52.0 forecast.
  • The stronger-than-expected data points to resilient domestic demand despite ongoing trade frictions and elevated input costs.

Economic Momentum Builds

US private sector activity accelerated at a faster-than-expected clip in October, with the S&P Global Composite Purchasing Managers' Index climbing to 54.8 from 53.9 the previous month. The reading marks the strongest expansionary signal since June and comfortably exceeded consensus estimates among economists surveyed ahead of the release.

The services sector drove much of the momentum, with its PMI jumping to 55.2 compared to the 53.5 estimate. Manufacturing activity also strengthened, reaching 52.2 against expectations of 52.0. Readings above 50 indicate expansion.

"The October data deliver a positive surprise after several months of moderating growth," said an economist familiar with the preliminary findings, who requested anonymity as the full report hasn't been published. "Service providers reported the sharpest rise in new business since May, while manufacturing output growth accelerated modestly."

Underlying Drivers and Market Implications

Survey respondents cited resilient consumer spending and solid business investment as key drivers behind the improved performance. The stronger data comes despite persistent trade tensions and the dampening effect of US tariffs on export demand, particularly affecting manufacturing sales to Canada and Mexico.

Input cost inflation remained elevated, according to people familiar with the survey details, though the pace of increase moderated slightly from September. Service sector firms reported the sharpest rise in employment since July, suggesting continued labor market strength.

Financial markets reacted positively to the news, with equity futures edging higher and Treasury yields ticking up as traders weighed the implications for Federal Reserve policy. The robust services reading particularly caught investors' attention, as it suggests the US economy continues to defy global growth concerns.

Looking Ahead

While the October figures point to stronger near-term economic momentum, economists caution that the outlook remains clouded by geopolitical uncertainties and the cumulative impact of previous interest rate hikes. S&P Global's data collection period for this preliminary reading ran from October 12-21.

Efforts to reach S&P Global representatives for additional comment outside regular business hours were unsuccessful. The final PMI readings for October will be published in early November.

Correction: An earlier version of this article misstated the previous month's composite PMI reading. It was 53.9, not 54.9.
