U.S. wholesale prices surged last month as the war in Iran drove up the cost of energy. The Labor Department reported that its producer price index, which measures inflation before it hits consumers, rose 0.5% from February and 4% from March 2025, the biggest year-over-year gain in more than three years.

Why it matters

The surge in wholesale prices complicates the work of the Federal Reserve, which has faced pressure to lower interest rates but may now need to raise them to combat the inflation threat from higher energy costs. The rising prices could also become a political issue ahead of the midterm elections, with food prices being a particular concern.

The details

The Labor Department's producer price index, which measures inflation before it hits consumers, rose 0.5% from February and 4% from March 2025. Excluding volatile food and energy prices, core producer prices rose a more modest 0.1% from February and 3.8% from a year earlier. The gains in wholesale prices were smaller than economists had forecast. Energy prices surged 8.5% from February, while food prices fell 0.3% after a 2.4% jump the previous month.

  • The Labor Department reported the data on Tuesday, April 14, 2026.
  • The year-over-year gains were the biggest in more than three years.

What they’re saying

“The decline in food prices is overdue, and welcome news for everyone. Food price increases are at the core of political arguments over affordability.”

— Carl Weinberg, Chief Economist, High Frequency Economics

“A small bit of economic pain for a few weeks is worth taking off the incalculable tail risk of the either a nuclear Iran or a nuclear Iran that uses that weapon.”

— Scott Bessent, U.S. Treasury Secretary

What’s next

Diplomats are continuing attempts to arrange a new round of peace talks between the United States and Iran to try to end the conflict, which has driven up energy prices and contributed to the surge in wholesale inflation.

The takeaway

The surge in wholesale prices driven by the Iran war poses a challenge for the Federal Reserve, which must balance fighting inflation with avoiding measures that could further slow the economy. The rising costs could also become a political issue, with food prices being a particular concern for consumers.
