FX.co ★ US Core PPI Accelerates to 5.0% YoY in September, Up from 4.6%

Core producer price inflation in the United States picked up in September 2026, signaling renewed cost pressures at the wholesale level. According to the latest release updated on 15 October 2026, the Core Producer Price Index (PPI) rose 5.0% year-over-year in September, compared with a 4.6% annual increase recorded in August 2026.

The data, measured on a year-over-year basis, show that underlying producer prices—excluding volatile components—are rising at a faster pace than in the previous month. The “previous” figure reflects the change in August 2026 relative to August 2025, while the current “actual” reading compares September 2026 with September 2025. This acceleration in core producer prices may draw close attention from market participants monitoring the trajectory of underlying inflation pressures in the US economy.
