U.S. Diesel Prices Reach Record High, Fueling Inflation and Growth Concerns
The U.S. average diesel price reached a record $6.069 per gallon on September 11, with California seeing prices near $8. This marks the first time in history that U.S. diesel has exceeded $6. Prices have surged by around 28% over three months and more than 70% since January 2026, adding to inflationary pressures as signs of renewed price acceleration emerge. The surge is attributed to constrained crude oil supplies and a tight global refining market due to conflicts in the Middle East. Attacks on shipping through the Strait of Hormuz and energy infrastructure have disrupted flows, while Ukrainian strikes on Russian refineries further complicate supply chains. The International Energy Agency reported that Saudi Arabia’s crude output fell sharply in August following attacks. Diesel's role as a critical input for transportation and industry means higher prices could impact both inflation and economic growth more significantly than headline crude oil prices alone.
