While global oil demand is set to decline this year due to the US-Iran conflict, gasoline consumption in the United States increased in the second quarter of 2026.
Gasoline prices surpassed $4.50 on average for a gallon of regular in the US in May, rising more than 50% since the start of the war, according to AAA data.
But that didn’t stop drivers from hitting the road; in fact, gasoline consumption rose in the US during the second quarter of the year, according to AP.
One reason may be because the percentage of household income spent on gasoline in the US has been declining for years, said Daniel Sternoff, senior fellow at the Center on Global Energy Policy at Columbia University. Plus, many people have been transitioning from remote work to in-office jobs, he added.
“Even though it’s a really political price that people pay a lot of attention to, if you are in the higher quintiles of income in the US, you might grumble about it, but you’re not really driving less just because of that increase in prices,” Sternoff said.
Jim Burkhard, vice president and head of crude oil research at S&P Global Energy, said, “The future of Hormuz is probably more uncertain today than it was at the beginning of the war.”
Burkhard said Iran is still trying to control the strait, while the US has not been able to fully restore normal operations, making a return to prewar conditions unlikely.
Global oil demand averaged just 97.9 million barrels per day in May, down 5.3 million barrels per day from a year earlier. Much of the decline was in Asia, which relies heavily on oil from the Middle East.
According to a report from the International Energy Agency Global, oil demand is set to decline this year for the first time since the height of the COVID-19 pandemic in 2020.
The drop, which the agency expects to amount to about 1 million barrels per day in 2026, is due to higher oil prices and disruptions to physical supply that weighed heavily, but unevenly, on various parts of the world, the report said.
The supply disruptions were caused by the war between the US and Iran, which left ships loaded with crude oil stranded in the Arabian Gulf for more than three months, unable to safely travel through the Strait of Hormuz, a major route for oil and gas shipments.
But the main exception to the global slump in oil usage was in the US, where gasoline use increased in the second quarter of 2026, despite the fact that pump prices were about 50% above their prewar levels in May, the report said.
