# US S&P Global Flash Composite PMI (September) — 2026-09-23

> US Composite PMI surges to 58.4 in September, beating the 56.0 forecast

## DATA
- Actual: 58.4 index points
- Forecast: 56.0 index points
- Previous: 56.0 index points
- Surprise vs forecast: hotter

## WHAT IT MEANS
The S&P Global Composite PMI tracks combined manufacturing and services activity in the US. A reading above 50 signals expansion; 58.4 is the highest in over five years, pointing to a booming economy.

## MARKET IMPACT
The upside surprise reinforces bets that the Fed will keep rates higher for longer, lifting the dollar and Treasury yields. Equities could react mixed: strong growth supports corporate earnings, but higher rates raise the cost of capital.

### Affected markets
- US Dollar (DXY) ↑ — Stronger growth data reduces the odds of near-term Fed rate cuts, supporting the dollar
- US Treasury yields ↑ — Hot growth data pushes back on rate-cut expectations, lifting yields
- US equities → — Strong growth is positive for earnings but higher-for-longer rate expectations offset the boost
- Emerging market currencies ↓ — A stronger dollar and higher US yields typically pressure EM currencies

## LEARNING
A big beat on an activity gauge like the PMI often makes markets reprice monetary-policy expectations before they celebrate the growth itself — 'good economic news' isn't automatically 'good news for every asset' at the same time.
