U.S. wholesale inflation accelerated in April to the fastest pace since 2022 on a war-driven increase in energy prices that's feeding into higher freight transportation costs.
The producer price index rose six per cent from a year ago, according to Bureau of Labor Statistics data out Wednesday. That topped all estimates in a Bloomberg survey of economists. The monthly gain was also the sharpest since 2022.
Core Measure Surges
A core measure of wholesale inflation that excludes food and energy increased 5.2 per cent from April 2025 — the biggest advance in more than three years. This core reading highlights underlying price pressures beyond volatile energy and food categories.
The yield on the 10-year Treasury note moved higher and stock-index futures fluctuated after the figures were released.
Broader Economic Impact
The inflation snapshot at the wholesale level follows Tuesday data that showed a steep annual increase in consumer prices. With a fragile truce in place and no end to the Middle East conflict in sight, other goods and services risk becoming more expensive as companies seek to pass on high energy and transportation costs.
The PPI data likely reinforce Federal Reserve officials' views that inflation should remain their top concern in the face of the war-driven surge in oil prices that's starting to ripple through to other parts of the economy.
“This report will set off alarm bells at the Fed and add fuel to the political conversation about affordability,” Carl Weinberg, chief economist at High Frequency Economics, said in a note. “They suggest that energy price increases are indeed ‘bleeding’ into core prices at the producer level.”
Components Breakdown
The PPI report showed goods prices, which include fuels, also increased by the most since 2022. Energy costs rose 7.8 per cent in April following an even larger advance in the prior month.
Services costs climbed 1.2 per cent, the most in four years. Prices for transportation and warehousing services — a category forecasters had flagged as especially sensitive to the conflict — jumped five per cent, driven by trucking and higher margins at fuel retailers.
The PPI report showed costs for truck transportation of freight jumped 8.1 per cent — the most in data back to 2009. Margins for machinery and equipment wholesalers also climbed substantially.
Fed's Preferred Gauge
Several components of the PPI are of particular interest because they feed into the Fed's preferred inflation gauge, the personal consumption expenditures price index. Those categories were mixed in April. While airfares and healthcare costs rose, portfolio management fees declined. The Bureau of Economic Analysis is scheduled to release April PCE price data, along with income and spending figures, on May 28.
While the labour market is showing some momentum, consumer sentiment now stands at record lows and inflation-adjusted wages are falling, which could put a dent on household spending — and therefore economic growth — later this year. Fed officials have indicated the central bank is unlikely to reduce interest rates in the near future.
Intermediate Demand Pressures
Another PPI measure pointed to persistent inflation pressures earlier in the production process. The costs of processed goods for intermediate demand increased 5.6 per cent in the past two months, the largest such advance in five years. Even excluding food and energy, prices of processed goods accelerated in April.
