AAA said on Tuesday that gas prices were expected to increase another 10 to 20 cents through the end of August. The average price of a gallon of regular in the United States has risen to $3.13, according to AAA, up from $3.05 a month ago. A year ago, as the pandemic kept people home, a gallon of gas cost just $2.18 on average.

The rise comes amid a breakdown in talks among OPEC and its allies over whether to expand oil production as travel resumes and global demand recovers. The cartel has been unable to reach a deal despite multiple meetings since Thursday.

“Robust gasoline demand and more expensive crude oil prices are pushing gas prices higher,” Jeanette McGee, an AAA representative, said in a statement. “We had hoped that global crude production increases would bring some relief at the pump this month, but weekend OPEC negotiations fell through with no agreement reached.”
