The national average price for a gallon of regular gas continued its volatile trend on Monday, sitting at $4.0636. The latest pricing is a very slight decrease from the weekend but remains higher than a week ago. On Sunday, the national average was $4.0656 per gallon, and a week ago, a gallon of regular gas was $4.0091.

The national average price of gas has fluctuated widely in 2026, ranging from a low of $2.79 per gallon in January to $4.562 per gallon in May. The most recent uptick in prices marks the third time the national average price for a gallon of regular gas has eclipsed $4 per gallon, which is a record, as the Washington Examiner previously reported. The recent fluctuation in gas prices has been linked to geopolitics in the Middle East, specifically the military conflict between Iran, Israel, and the United States, and turmoil involving the Strait of Hormuz.
