U.S. wholesale prices surged last month as the ongoing 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 year-over-year gain was the biggest in more than three years, with energy prices surging 8.5% from February.

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 need to raise them to combat the inflation threat from higher energy costs. The impact on consumer prices, especially for food, could also become a political issue ahead of the midterm elections.

The details

Excluding volatile food and energy prices, so-called 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. The war in Iran is expected to lead to an annual decline in oil demand for the first time since the pandemic, with the International Energy Agency forecasting a drop of 80,000 barrels per day this year.

  • The Labor Department reported the data on Tuesday, April 14, 2026.
  • The year-over-year gains in the producer price index were the biggest since March 2025.

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

What’s next

The Federal Reserve will need to carefully consider its next steps in monetary policy to address the surge in wholesale prices while also balancing concerns over economic growth.

The takeaway

The sharp rise in U.S. wholesale prices, driven by the ongoing war in Iran and its impact on energy costs, presents a complex challenge for the Federal Reserve as it tries to maintain price stability and support economic growth. The political implications of higher consumer prices, especially for food, could also become a key issue in the upcoming midterm elections.
