FX.co ★ US Core PCE Inflation Accelerates to 0.5% in September, Raising Policy Pressure

The U.S. Personal Consumption Expenditures (PCE) price index, the Federal Reserve’s preferred gauge of inflation, accelerated in September 2026, underscoring persistent price pressures in the economy. Month-over-month, the index rose 0.5%, up from a 0.3% increase recorded in August 2026.

On a comparative basis, the “actual” figure for September reflects the change from August to September, while the “previous” figure captures the change from July to August. The pickup from 0.3% to 0.5% signals a re‑acceleration in consumer price growth, a development that could complicate the Fed’s path on interest rates if sustained.

The latest data, updated on 29 October 2026, will likely sharpen market focus on upcoming Fed communications and projections, as investors reassess the trajectory of inflation and the potential need for tighter-for-longer monetary policy in the United States.
