US Business Activity Surges to 5-Year High in September

Key Facts

In a move reflecting a sharp acceleration in US economic momentum, private sector activity surged in September. According to reports, the US Composite PMI rose to 58.4, marking its highest level in 62 months. This expansion was driven by four consecutive months of accelerating growth, with the manufacturing sector hitting a 52-month high of 57.0 and the services sector reaching a 59-month peak of 58.7.

This robust performance is attributed to simultaneous increases in output, hiring, and price pressures across sectors. Per analyst data, the acceleration reflects strong domestic demand that pushed manufacturing payroll growth to its fastest rate since February 2021. However, reports indicate a renewal of inflationary signals as input costs rose at their quickest pace since late 2022, fueled by higher fuel, transport, and wage expenses.

Looking at the macro landscape, these strong figures follow the Federal Reserve's decision on September 16, 2026, to raise interest rates to 4%, according to economic calendar data. With business activity hitting multi-year highs, investors are watching how this economic strength will influence monetary policy under Fed Chair Kevin Warsh, especially as new orders continue to accelerate and capacity constraints tighten.
