(July 28, 2023) WASHINGTON, D.C. —The national average for a gallon of gas awoke from a months-long slumber, surging 13 cents since last week to $3.71. The primary cause appears to be the oil price, which has marched nearly $4 higher in the past few days to hover near $80 per barrel.  As oil accounts for almost 50 percent of the cost of a gallon of gas, higher oil prices usually mean higher pump prices.

“Gas demand, meaning people fueling up, remains tepid. It’s lower now than at this time last year and in 2021,” said Andrew Gross, AAA spokesperson. “But while the heat may be keeping some folks home, it also suppresses refinery production, according to experts.  Constrained supplies and a higher cost of oil are tipping the balance toward rising pump prices for now.”

According to new data from the Energy Information Administration (EIA), gas demand rose slightly from 8.86 to 8.94 million barrels a day last week. Meanwhile, total domestic gasoline stocks dipped from 218.4 to 217.6 million barrels. With supplies tight, if demand should spike, pump prices will follow suit.

Today’s national average of $3.71 is 15 cents more than a month ago but 59 cents less than a year ago.
