US Gas Prices Surge Past $4 Per Gallon Amid Iran War

U.S. gas prices have jumped past an average of $4 per gallon for the first time since 2022, driven by the ongoing war between the U.S., Israel, and Iran that has caused major disruptions to global oil supply and production. According to AAA, the national average for a gallon of regular gasoline is now $4.02, over a dollar more than before the conflict began.
Why it matters
Higher gas prices are impacting both consumers and businesses, as the increased cost of fuel is driving up the prices of many goods and services. This could further strain household budgets that are already facing wider cost-of-living pressures. The disruption to the global oil supply due to the Iran war is a key factor behind the price surge at the pump.
The details
The price spike is a result of the conflict between the U.S., Israel, and Iran that began on February 28th. This has caused major supply chain disruptions and production cuts from major oil producers in the Middle East, leading to a sharp rise in the cost of crude oil, the main ingredient in gasoline. Refineries are also dealing with more expensive oil that they purchased in advance, and the switch to more costly summer blend fuel has added to the price increase.
- The national average gas price surpassed $4 per gallon on March 31, 2026.
- The last time U.S. drivers paid this much at the pump was nearly four years ago, following Russia's invasion of Ukraine in 2022.
The players
AAA
A motor club that tracks and reports on national average gas prices.
United States
The U.S. government and military, which launched a joint war against Iran on February 28th, 2026.
Israel
The U.S. ally that joined in the military conflict against Iran.
Iran
The country engaged in the ongoing war with the U.S. and Israel, which has disrupted global oil supply and production.
What’s next
The Biden administration has pledged to release 400 million barrels of oil from emergency stockpiles of member nations in the International Energy Agency in an effort to cut prices. The White House has also temporarily eased sanctions to free up some oil from Venezuela and Russia.
The takeaway
The surge in gas prices driven by the Iran war highlights the vulnerability of the U.S. economy to global oil supply disruptions, even as the country has become a net oil exporter. The price hikes are straining household budgets and driving up the costs of many consumer goods, underscoring the need for policies to enhance energy security and resilience.
