“The national average price of gasoline has seen its first weekly increase since May 11, snapping a streak of eight straight weekly declines, with prices climbing in nearly four out of five states,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The turnaround comes as oil prices have surged following the collapse of the ceasefire between the U.S. and Iran and the start of new attacks, with oil jumping another 4% in Sunday evening trading, an ominous sign that could bring additional gas and diesel price increases in the week ahead. While the pace of increases doesn’t yet appear likely to match what motorists experienced in March and April, fresh Ukrainian attacks on additional Russian refineries will only add to the pressure, keeping supplies of refined products tight even as the situation remains fluid.”
