AAA’s national average for a gallon of regular gasoline slid to $3.938, holding below $4 and extending a steady decline as crude oil trades near multi-month lows on the U.S.-Iran de-escalation. The motor club’s latest update is headlined “National Average Drops Below $4/Gallon as Summer Travel Heats Up,” a welcome alignment of falling prices and peak driving season.
The pullback tracks the slide in crude, which has fallen sharply since the interim peace deal took effect: WTI settled around $74.82 a barrel and Brent near $77.90, both down steeply from above $100 at the height of the conflict. Because retail gasoline lags the futures market by one to two weeks, a portion of the recent crude decline has yet to reach the pump, pointing to further relief as long as the de-escalation holds and the Strait of Hormuz keeps reopening.
Diesel, a key cost input for freight and agriculture, eased to a national average of $5.040. The distillate premium remains historically wide, a lingering effect of the war’s disruption to refining and middle-distillate supply, but it has been grinding lower in step with crude.
State-level prices continue to span a wide range. Indiana is the cheapest market in the country at $3.34 a gallon, with Oklahoma ($3.44), Texas ($3.44), South Carolina ($3.51), and Tennessee ($3.52) also among the lowest. California remains the most expensive at $5.58, followed by Washington ($5.36), Hawaii ($5.56), and Oregon ($4.85). The gap reflects the usual mix of state taxes, fuel-blend requirements, and refining and distribution costs.
The outlook is lower, with caveats. A fully reopened Hormuz and the return of disrupted Gulf supply would keep downward pressure on crude and, with it, the pump, into the summer. The risks run the other way only if the fragile peace frays — through a renewed strike threat, a Lebanon escalation, or a breakdown in the 60-day negotiation — the kind of event that has repeatedly snapped prices higher over the past four months.
For now, drivers are getting the clearest relief since the war began. The national average has fallen well off its spring highs above $4.50, and sub-$4 gasoline arriving at the start of peak travel season marks a notable turn for household budgets.
