The national average price of regular gasoline in the U.S. fell below $4 per gallon on Thursday [1].
This price drop provides temporary relief to consumers after months of volatility driven by geopolitical tensions in the Middle East. The shift reflects a sudden change in market sentiment regarding the stability of global oil shipments.
The national average price of regular gasoline fell to $3.99 per gallon [1]. This represents the lowest national gasoline price since March 30, 2026 [2].
The decline follows progress on a diplomatic front. The U.S. and Iran signed a memorandum of understanding to reopen the Strait of Hormuz [3]. This critical waterway is a primary artery for global oil exports, and the agreement has eased market concerns over potential supply disruptions [4].
Despite the current dip, costs remain significantly higher than in previous periods. Gas prices are currently about $1 higher than they were before the war [5]. Additionally, prices remain roughly 25% higher than they were last year [6].
Market analysts said that while the memorandum of understanding has removed a primary risk premium from oil prices, the long-term trend depends on the full implementation of the agreement. The dip below the $4 threshold is the first such occurrence in nearly three months [1].
“The national average price of regular gasoline fell to $3.99 per gallon.”
The dip in gasoline prices is a direct reaction to the mitigation of a 'geopolitical risk premium.' Because the Strait of Hormuz is a global chokepoint for oil, any agreement to ensure its openness reduces the fear of supply shocks. However, the fact that prices remain 25% higher than last year suggests that structural inflation or underlying supply constraints continue to keep the baseline cost of fuel elevated despite the diplomatic breakthrough.
