U.S. Fuel Prices Surge Dramatically Amid Escalating Middle East Conflict and Supply Disruptions

Michigan households have paid an estimated average of nearly $860 more for fuel since the Iran war began in late February, while filling a 15-gallon tank cost nearly $10 more than it did the previous week.
Michigan’s governor temporarily suspended environmental regulations in eight counties — Wayne, Oakland, Macomb, Washtenaw, Livingston, Monroe, St. Clair and Lenawee — allowing stations there to begin selling the cheaper winter-blend gasoline earlier than elsewhere.
The Great Lakes refinery problems affected more than Michigan: GasBuddy analyst Patrick De Haan said Michigan, Indiana, Illinois, Ohio and Wisconsin each saw gasoline prices rise by more than 30 cents per gallon in the past week.
AAA said the national gasoline average of $4.43 was approaching this year’s high of $4.56, recorded on May 21, as crude oil averaged about $100 per barrel.
Baton Rouge residents described the impact on household budgets: Quiana Revish said that $30 now barely fills half her tank, while another resident reported spending nearly $100 a week on gasoline.
U.S. fuel prices are climbing sharply, with national gasoline averaging $4.43 to $4.47 per gallon—up 16 cents in just one week and over $1 from a year ago. Reuters reports that diesel futures in Europe closed at record highs last week, more than double their start-of-2026 levels. The surge stems from Middle East conflict disrupting oil supplies and threatening shipments through the Strait of Hormuz.
Michigan residents face the steepest pain, with regular gasoline at $4.91 to $4.93 per gallon—a 2026 high—and diesel hitting a record $6.81, exceeding $7 at some stations. GasBuddy data shows Michigan, Indiana, Illinois, Ohio, and Wisconsin each saw prices jump more than 30 cents per gallon in the past week. Filling a 15-gallon tank in Michigan now costs about $74, roughly $10 more than the previous week.
Reuters reports that diesel prices have hit record highs in both Europe and the United States as wars in Iran and Ukraine have sharply cut exports from major producers including Russia, Saudi Arabia, and the UAE. Crude oil now averages around $100 per barrel. According to AAA, the national gasoline average of $4.43 is approaching this year's high of $4.56, set on May 21.
Michigan residents have paid an estimated $860 more for fuel on average since the Iran war began in late February. Prices vary across the state: Marquette averages $4.79 per gallon, while Ann Arbor reaches $4.97. Southwest Michigan county averages range from $4.89 to $4.99. Indiana's average is lower at $4.01 thanks to a temporary gas-tax holiday.
Governor Gretchen Whitmer temporarily suspended environmental regulations in eight counties—Wayne, Oakland, Macomb, Washtenaw, Livingston, Monroe, St. Clair, and Lenawee—allowing stations to sell cheaper winter-blend gasoline earlier. This move aims to ease pressure on household budgets as families adjust to higher fuel costs.
WSET reports that in Lynchburg, Virginia, gasoline reached $4.16 per gallon while diesel climbed to $6.28. In Baton Rouge, gasoline approached $4 per gallon and diesel exceeded $6. Diesel futures in Europe closed at all-time highs last week due to supply disruptions in the Red Sea, with the Middle East seeing its diesel exports cut in half, according to Reuters.
Residents report the pinch is immediate and severe. In Baton Rouge, Quiana Revish said $30 barely fills half her tank now. Another resident reported spending nearly $100 per week on gasoline. These real-world impacts show how global conflict directly hits American household finances, with families forced to cut back on other expenses.
