U.S. Fuel Prices Spike Amid War with Iran

A military conflict between the United States and Israel against Iran, which began on February 28, 2026, has triggered a global energy crisis. The closure of the Strait of Hormuz and Iranian strikes on Gulf infrastructure crippled oil shipments, driving U.S. gasoline prices to a peak of $4.17 per gallon by early April. While prices recently retreated to approximately $4.03, the surge has fueled the largest year-over-year inflation increase since May 2024.

Donald Trump has faced political fallout as 51% of registered voters blame his administration for the spike, contributing to a drop in his economic approval rating to 30% in April. While Trump asserts prices will fall "as soon as this ends," Energy Secretary Chris Wright warned that supply challenges could persist through the end of the year. Tensions remain high as Iran recently seized two container ships in the Strait of Hormuz despite a brief ceasefire.

The economic impact extends beyond the pump. Diesel prices surged 45%, leading 18% of surveyed trucking firms to temporarily halt operations. In the aviation sector, United Airlines and Lufthansa cut services, with United raising ticket prices by 15% to 20% and increasing baggage fees. Globally, the crisis has spurred fuel thefts in the UK and Australia, while Russia banned gasoline exports to protect domestic supplies. Some analysts, including journalist Lauren Fix, argue that while the war is a catalyst, regional taxes and infrastructure limits also drive the final cost for consumers.
