U.S. Diesel Prices Hit Record High, Raising Cost Pressures on Consumers and Industry

The average price of diesel in the United States climbed to a record $6.45 per gallon this week, marking a 74% rise from the same period last year. The surge is expected to lift transportation costs for freight, agriculture and trucking, which could translate into higher prices for food and everyday products.

Analysts attribute the price jump to disruptions in global oil supplies caused by the wars in Ukraine and Iran, as well as Russian export controls and attacks on refineries in both countries. The International Energy Agency noted that flows through the Strait of Hormuz have fallen sharply, reducing global oil availability.

"Diesel is different than gasoline; it’s like the silent partner in this," said Mark Finley, an energy fellow at the Baker Institute. He added that diesel is embedded in virtually every sector of the economy.

Industry experts warned that the higher fuel cost will likely be passed on to consumers. Thomas Kloza, Gulf Oil’s chief energy adviser, said that when diesel prices rise, companies that rely on the fuel tend to increase prices gradually, which can add 2% to 4% to retail food costs during a 10%-15% fuel price increase.

The military also faces increased expenses, as many vehicles and aircraft run on diesel. The Navy has asked Congress for additional funding to cover the impact on routine operations, including training limits.

U.S. refineries are operating near full capacity to meet demand, but analysts say the market will remain tight through the fall and into winter. Some lawmakers have suggested limiting diesel exports to ease domestic prices, though the administration has not pursued such a ban.

Experts agree that easing geopolitical tensions and restoring refinery output in Russia, Iran and Ukraine would be the most effective way to stabilize diesel prices.
