U.S. regular gasoline averaged $4.1505 per gallon over Labor Day, the highest AAA has recorded for the holiday and about 30% above the $3.20 average a year earlier. Diesel also reached a holiday-period record of $5.90 per gallon. Crude prices, constrained oil traffic through the Strait of Hormuz and refinery outages linked to the Iran War and Russia-Ukraine War have tightened fuel supplies, although Energy Secretary Chris Wright expects seasonal demand to weaken, gasoline production to increase and pump prices to ease after Labor Day. An early Environmental Protection Agency waiver for winter-blend gasoline may provide relief. Polymarket assigned a 2% probability to crude oil reaching a new all-time high by September 30 and 9.5% by December 31.
