US Wholesale Inflation Hits Four-Year High in October
The US Producer Price Index rose 6.5% year-over-year in October, prompting Federal Reserve officials to signal further interest rate hikes in December.
The Federal Reserve System is facing renewed inflationary pressure after the U.S. Producer Price Index (PPI) reached a four-year high on November 13, 2026. Wholesale inflation rose 6.5% year-over-year in October, marking the fastest pace of growth since November 2022.
Headline producer prices grew 0.3% month-over-month, slightly below the 0.4% forecast. This increase was primarily driven by soaring food prices and the impact of artificial intelligence on memory prices, despite a monthly deflationary trend in energy. Core PPI, which excludes food and energy, rose 0.3% month-over-month and 5.0% year-over-year, indicating that intermediate demand remains high.
The surge strengthens the position of officials advocating for continued monetary tightening. Federal Reserve governors Christopher Waller and Adriana Logan have expressed support for further interest rate hikes in December. These figures have complicated arguments for a pause in the tightening cycle and triggered market repricing in Treasuries and growth equities, with markets now pricing in a 15% probability of a 50-basis-point increase in December.
