American drivers are continuing to feel the effects of the war involving Iran, with gasoline prices climbing sharply across nearly the entire country.
According to AAA data released Tuesday morning, the national average price for a gallon of regular gasoline reached $4.56, an increase of more than 50% since the conflict began earlier this year.
Gas prices are now above $4 per gallon in 49 states and Washington, D.C. Oklahoma remains the only state with an average below that mark, at $3.99 per gallon. The average price in Washington, D.C., stood at $4.61.
The spike follows months of instability in global oil markets tied to fighting in the Middle East and disruptions involving the Strait of Hormuz, a key shipping route for international oil supplies. Concerns over supply interruptions have driven oil prices higher and contributed to the sharp increase at the pump.
Analysts say consumers are unlikely to see a quick return to the lower fuel prices seen earlier in 2026, even if diplomatic efforts between the United States and Iran succeed in reducing tensions.
Patrick De Haan, head of petroleum analysis at GasBuddy, said any significant relief would depend heavily on the full reopening of the Strait of Hormuz to normal shipping traffic. Even then, he said, it could take until early or mid-2027 for prices to fall back to prewar levels.
The current national average is among the highest recorded in recent years. AAA tracking data show gasoline prices peaked at just over $5 per gallon during earlier global supply disruptions, then eased in late 2025 and early 2026.
Higher fuel costs are also raising concerns about broader inflation and the impact on summer travel. Memorial Day and vacation season traditionally lead to increased driving demand, which could place additional pressure on prices in the weeks ahead.
Economists say prolonged instability in the Middle East, combined with strong seasonal demand, could keep prices elevated even if military tensions begin to ease.
