US wholesale prices jump 4% as Iran war fuels energy surge

US wholesale prices jump sharply in March, underscoring how quickly the Iran war is feeding into the American economy through higher energy costs.

Producer prices rose 0.5% from February and 4% compared with a year earlier, the biggest annual increase in more than three years, according to data released Tuesday by the U.S. Department of Labor.

The main driver: energy. Prices in that category surged 8.5% in just one month.

The spike is already complicating the outlook for inflation—and for policymakers.

At the Federal Reserve, officials are facing renewed pressure from President Donald Trump to cut interest rates. Yet rising energy costs could push the central bank in the opposite direction.

Some policymakers are now weighing whether rates may need to stay higher for longer—or even rise further—to contain inflation risks.

Strip out volatile food and energy, and the picture looks calmer. Core producer prices increased just 0.1% from February and 3.8% year over year, suggesting underlying inflation pressures remain more contained—for now.

Still, headline numbers matter. Wholesale inflation often signals where consumer prices are headed next.

Recent data already points in that direction. Consumer prices rose 3.3% in March from a year earlier, with gasoline costs driving much of the increase.

Energy markets are at the center of the shift.

The conflict with Iran has disrupted supply chains and shaken oil flows, particularly through the Strait of Hormuz—a key artery for global energy transport.

According to the International Energy Agency, oil demand is now expected to fall this year for the first time since the pandemic. That reversal reflects both supply disruptions and weakening global consumption.

Back in the U.S., the impact is already visible at the pump.

Gasoline prices remain above $4 per gallon on average—roughly 30% higher than a year ago—even after a slight decline in recent days.

Treasury Secretary Scott Bessent acknowledged the short-term pain but framed it as part of a broader geopolitical strategy, arguing that stabilizing the region could ultimately ease inflation pressures.

For now, uncertainty dominates.

There is no clear timeline for the end of the conflict. Diplomatic efforts to restart negotiations between Washington and Tehran are ongoing, but markets remain on edge.

And as long as energy prices stay elevated, the risk is that inflation will follow—keeping pressure on consumers, policymakers, and the broader economy.
