The U.S. S&P Global Composite PMI rose to 58.4 in September 2026, up from 56.0 in August, according to the latest data updated on 23 September 2026. The reading signals a stronger expansion in overall private sector activity, as the index moves further above the 50-point threshold that separates growth from contraction.
The latest increase suggests that both manufacturing and services continued to gain momentum at the end of the third quarter, with the September figure marking a clear acceleration compared with the previous month. While detailed sector breakdowns were not provided, the composite improvement indicates broad-based resilience across the U.S. economy during the period.
With the index now at its highest level since at least August, investors and policymakers may interpret the September jump as evidence of sustained economic strength, potentially influencing expectations around corporate earnings, credit conditions, and the future path of monetary policy in the United States.
