U.S. gasoline prices reached $4.14 per gallon before Labor Day, up from $3.20 a year earlier, as the Iran war and broader geopolitical tensions heightened concerns about energy supplies and household costs. Sen. Bernie Sanders cited a $4.15 national average and blamed President Donald Trump’s Iran war, while analysts said prices could still fall below $4 by Labor Day. Earlier projections had put Labor Day gasoline at $4.03, and prediction markets assigned 1.7% YES odds to crude reaching a new all-time high by September 30 and 9.5% by December 31. Markets are also monitoring the Strait of Hormuz, Ukrainian strikes on Russian refineries, OPEC policy, WTI crude prices and seasonal gasoline changes.
