FX.co ★ US Core PPI Accelerates to 4.6% in August, Underscoring Persistent Inflation Pressures

Core Producer Price Inflation in the United States picked up in August 2026, signaling renewed pressure in the pipeline for consumer prices. Year-over-year, the Core PPI rose to 4.6%, up from 4.2% in July 2026, according to data updated on 10 September 2026.

The figures, measured on a year-over-year basis, compare August 2026 producer prices excluding food and energy to those in August 2025, while the previous reading reflected the change in July 2026 versus July 2025. The acceleration suggests that underlying input costs for businesses are once again climbing, potentially complicating the inflation outlook and monetary policy expectations.

With core producer prices rising faster than in the prior month, markets and policymakers are likely to scrutinize whether this marks a temporary uptick or the start of a more sustained re-acceleration in underlying inflation pressures.
