The national average price for a gallon of regular gasoline broke records repeatedly during the first two weeks of May, according to the American Automobile Association.
AAA is a privately held not-for-profit national member association and service organization with more than 60 million members in the United States and Canada. AAA’s nationwide survey on gas prices found that, as of May 16, 2022, nearly every state has passed the $4 per gallon price.

Gas price fluctuations—up 30.8% per gallon in the U.S. from one year ago—are felt on a personal level, but they’re often influenced by sudden events and major policy shifts across the country and world.
Natural disasters like hurricanes that shut down refineries along the Gulf of Mexico—where roughly half of America’s crude oil is processed—can drive prices up almost immediately. As during the First Gulf War with Iraq in 1990-91 or with Russia’s invasion of Ukraine in February, military conflicts involving oil-producing countries can also cause ripple effects worldwide.
The cost of crude oil, set by global supply and demand, is the country’s most significant determinant for gas prices. Currently, high seasonal demand, rebounding travel in the wake of COVID-19 restrictions, weak domestic output, and international sanctions against Russia—a massive player in the global oil market—are all contributing to ever-increasing prices at the pump.
