Key Points
Energy prices jumped 10.7% month-over-month, the largest increase on record.
Year-over-year PPI rate hit 6.5%, highest since November 2022.
May marked ninth consecutive monthly PPI increase, showing persistent wholesale inflation.
Core prices excluding energy grew 0.4% monthly, below expectations of 0.5%.
US wholesale prices surged 1.1% in May, beating expectations of 0.7% growth, according to the Bureau of Labor Statistics. The year-over-year rate hit 6.5%, the highest since November 2022. Energy prices drove the gain with a record 10.7% monthly jump. This data matters because wholesale inflation often flows through to consumer prices, affecting purchasing power and influencing central bank policy decisions.
Energy Prices Hit Record Highs
Energy prices surged 10.7% month-over-month in May, the largest monthly increase on record. Gasoline jumped 23.4% (up 69.5% year-over-year), while diesel fuel climbed 15.7% (up 105.9% year-over-year). Home heating oil and distillates rose 16.3% (up 87.0% year-over-year). This was the fourth consecutive monthly energy gain, reflecting Middle East tensions that disrupted oil supply flows. Natural gas liquids increased 15.6% (up 37.5% year-over-year), though residential electric power fell 0.2%.
Core Prices Remain Elevated Despite Moderation
Producer prices excluding food and energy grew 0.4% month-over-month in May (4.9% year-over-year), below the expected 0.5% increase. A broader core measure—producer prices less food, energy, and trade services—advanced 0.8% (5.1% year-over-year), marking the strongest of 13 straight monthly gains. Food prices rose 0.6% (2.6% year-over-year), the third monthly increase in four months. These figures reinforce elevated inflationary pressures on both producer and consumer sides.
Ninth Straight Monthly Gain Signals Persistent Pressure
The May PPI marked the ninth consecutive month of increases, showing no relief in wholesale inflation. The year-over-year rate of 6.5% is the highest since November 2022, up from 5.7% in April and 2.7% in May 2025. Historical PPI data shows this acceleration mirrors the energy-driven shocks hitting global markets. Central banks including the ECB have already responded by raising rates to combat inflation transmission.
What This Means for Policy and Markets
The strong May PPI data complicates the outlook for the Federal Reserve and other central banks. Higher wholesale prices typically flow through to consumer inflation within weeks or months. The ECB raised rates 25 basis points on June 12 in response to energy-driven inflation. The Fed faces a balancing act: tightening to fight inflation risks slowing growth, while loose policy risks letting price pressures accelerate further.
Final Thoughts
US wholesale inflation hit its highest annual rate since November 2022, driven by record energy spikes. With nine straight monthly gains and core prices elevated, central banks face mounting pressure to contain price growth despite economic slowdown risks.
