(December 13, 2022) WASHINGTON, D.C. — The national average pump price plunged 14 cents since last week to $3.26, six cents less than a year ago. There are now approximately 34 states with averages lower than last year, according to the weekly report by AAA.Prius.

“The seasonal pattern of less driving due to shorter days and crummy weather, combined with a lower oil cost, is driving gas prices lower,” said Andrew Gross, AAA spokesperson. “If this trend continues, many states could see their average prices fall below $3 a gallon by early next year.”

According to data from the Energy Information Administration (EIA), gas demand remained low at 8.36 million b/d last week, approximately 605,000 barrels a day lower than a year ago. Meanwhile, total domestic gasoline stocks rose significantly by 5.3 million barrels to 219.1 million barrels. Increasing supply and lower gasoline demand will push pump prices lower.

Today’s national average of $3.26 is 52 cents less than a month ago and six cents less than a year ago.
