Fuel prices at record Labor Day high in US thanks to Iran War and refinery issues

US gas prices hit record highs for Labor Day as the Iran war disrupts oil flows through the Strait of Hormuz and diesel costs surge.

It's never been more expensive in the US to fill up the tank and take one last summer trip over the Labor Day weekend.

The average price of regular gas was $4.14 a gallon heading into the holiday, nearly a dollar higher than last year and well above the Labor Day weekend record of $3.82 from 2012, according to AAA motor club.

Prices shot up after the U.S. and Israel attacked Iran in February and have not settled down since. Crude oil traffic through the key Strait of Hormuz has plunged, and Iran has refused to reopen the waterway.

Energy Secretary Chris Wright offered few specifics on when the nation’s drivers might see relief at the gas pump, acknowledging that prices are higher now than Labor Day 2025.

“Yes, they’re higher today, but we’re doing everything we can to push them down," Wright said Sunday on ABC’s “This Week.”

The national average for regular gas prices is still well below the record of $5.02 a gallon set in June 2022.

But diesel is a different story: It hit a national average of $5.85 a gallon Friday, a record.

Trucks and other freight delivery systems use a lot of diesel, and that increased transportation cost is being passed on to consumers, whether at the grocery store or through package delivery services.

“It doesn’t really seem like there’s an end to it,” Collins said.

Gas prices typically drop as the summer driving season ends and refineries turn to making a cheaper winter blend.

But analysts said there are other factors this year even beyond the volatile situation in the Middle East that make future prices unpredictable.

US refineries are working at 98% capacity, many in the unusually harsh Texas heat. If there are problems there or a hurricane knocks some systems offline, prices will struggle to drop.

And it's not just a Middle East problem. Ukrainian drone attacks on Russian refineries are squeezing diesel supplies.

Wright, the energy secretary, said the Trump administration was taking steps to increase production and that the markets forecast lower prices in the coming months.

“If you look at the futures prices, if you wanted to buy today in bulk gasoline for two months out in November, it’s about $0.35 cheaper than it is today. So the marketplace thinks gasoline prices are going to move meaningfully lower," he said.
