The U.S. Department of Labor released data showing the Producer Price Index (PPI) for December 2024 surged by 0.5% month-over-month, significantly exceeding the market forecast of 0.2%. This marks the largest monthly gain in eight months and follows a revised 0.1% increase in November, indicating a concerning upward trajectory in wholesale inflation.
The core PPI, which excludes volatile food and energy components, rose 0.4% for the month and 2.6% over the past twelve months, remaining above the Federal Reserve's 2% target. The increase was broad-based, driven by a sharp 2.4% rebound in energy prices, a 0.8% rise in food prices, and continued strength in the services sector, particularly transportation and warehousing.
Financial markets reacted immediately, with Treasury yields rising on increased inflation expectations and the dollar strengthening as traders adjusted their outlook for Federal Reserve interest rate policy. Economists noted the data suggests underlying inflationary pressures are more persistent than recent consumer price declines indicated, potentially influencing the Fed's upcoming policy discussions.
Looking at the full year 2025 data (as revised from August through November), headline producer inflation reached 3.0%, beating the 2.7% forecast, while the core measure finished at 3.5%. The monthly jump was primarily driven by services, with the final demand services index rising 0.7%, its largest gain since July. A significant portion of this increase came from a 1.7% surge in trade service margins, particularly in machinery and equipment wholesaling, which jumped 4.5%.
