U.S. Gasoline Prices Surge to Four-Year High Amid Iran Conflict

AAA data show the national average gasoline price rose to $4.17 on Tuesday, up $1.19 since the Feb. 28 war began. The increase equals a 28 % rise in two months; a separate AAA report lists $4.18 and a 40 % jump. The price is the highest since April 2022, when it peaked at $4.11.

The U.S.–Israeli operation against Iran, launched Feb. 28, sparked a major oil shock. Iran closed the Strait of Hormuz, a chokepoint moving about one-fifth of global oil. The closure and brief reopenings constrained supply and heightened price pressure worldwide.

West Texas Intermediate futures traded above $99 per barrel and Brent crude topped $111. Crude oil now makes up more than half of pump prices, per the U.S. Energy Information Administration. Regional averages vary: California $5.97 per gallon, the highest, and Oklahoma $3.57.

President Donald Trump said Iran had urged the United States to reopen the Hormuz Strait, framing the demand as a test of Tehran’s leadership. Senator Marco Rubio, speaking on Fox News, rejected Iran’s offer to end hostilities without addressing its nuclear program, emphasizing that the nuclear question remains central. Iranian officials dismissed U.S. claims of an imminent nuclear threat, asserting that their program is peaceful.

A Reuters/Ipsos poll found 77 % of Americans hold President Trump at least partially responsible for the price surge, while 22 % disagree. Critics say the administration’s diplomatic stance has prolonged the Strait closure and heightened market uncertainty.

Sources differ on the exact national average—$4.17 versus $4.18—and on the percentage increase, reporting 28 % and 40 % respectively. No data detail the duration of the Strait’s closures beyond “twice reopened, then shut again,” leaving the timeline unclear.

• “There’s no doubt in my mind that at some point in the future, if this radical clerical regime remains in charge in Iran, they will decide they want a nuclear weapon,” — Marco Rubio, Senator

• “to ‘Open the Hormuz Strait,’ as soon as possible, as they try to figure out their leadership situation (Which I believe they will be able to do!)” — Donald Trump, President

• “ The Islamic Republic has rejected these claims, arguing that its nuclear program was designed for peaceful purposes.” — Iranian officials

Negotiators are reviewing Iran’s latest proposal to reopen the Strait while postponing nuclear discussions. A sustained reopening could ease crude-oil futures, potentially lowering gasoline prices, but continued diplomatic deadlock may keep pump prices elevated through the remainder of the year.
