Gasbuddy: gasbuddy Flags Biggest Single-Day U.S. Pump Jump in Four Years
gasbuddy data shows America’s average gas price surged by 11 cents on Tuesday morning ET, marking the largest single-day rise at the pump in four years. AAA said the national average for a gallon of regular climbed from $3. 00 on Monday to $3. 11 on Tuesday ET, while premium moved from $3. 86 to $3. 98. The spike followed expanded attacks by Iran and damage to energy infrastructure that have rattled markets and raised fears of supply disruptions.
Immediate facts: prices, timing, and scale
On Tuesday morning ET U. S. pump prices jumped an average of 11 cents nationwide, AAA said. That move pushed the national average for regular-grade gasoline from $3. 00 on Monday to $3. 11 on Tuesday ET, and premium averaged $3. 98, up from $3. 86. AAA noted this is the largest single-day increase at the pump since March 2022 and the first time the national regular average has topped $3 in 2026.
Gasbuddy analysis: Strait threats and market reaction
Patrick De Haan, head of petroleum analysis at GasBuddy, wrote that Iran has threatened ships traveling through the 21-mile Strait of Hormuz, where about 20% of the world’s crude oil supply passes. Those threats and recent launches of missiles and drones at regional targets have put immediate upward pressure on crude benchmarks. Brent crude hovered above $80 a barrel in mid-day trading ET, about 4% higher than on Monday ET, reflecting tightened sentiment in oil markets.
Regional disruptions and energy supply moves
On Monday ET, QatarEnergy throttled production of liquefied natural gas after drone attacks damaged one of its facilities, a move that added another layer of supply concern. Iran’s expanded actions — described in the context of retaliation for prior bombings — included strikes targeting Israel and U. S. bases in Bahrain, Iraq, the United Arab Emirates, and Qatar, intensifying market worries about a broader disruption to energy flows.
Reactions from institutions and drivers
AAA warned last Thursday ET that seasonal price pressures are beginning: “Spring weather may be weeks away in much of the country, but the seasonal rise in gas prices is underway, ” the institution wrote, adding that “Gas demand is also expected to increase next month as spring break season kicks off and more drivers take road trips. ” That combination of rising demand and supply risk forms a classic recipe for higher pump prices.
Patrick De Haan at GasBuddy highlighted the strategic risk posed by threats to the Strait of Hormuz, underscoring how regional security events can transmit quickly into consumer pump prices.
What’s next — watch the Strait, LNG output and seasonal demand
Markets and motorists should watch developments through the coming days in ET: any further escalation affecting the Strait of Hormuz or additional damage to energy facilities could sustain upward pressure on crude and retail prices, while the approaching spring travel season is likely to lift demand. Tracking institution statements, LNG production moves, and petroleum benchmark trading in real time will show whether Tuesday morning ET’s surge is a short shock or the start of a broader run-up in prices. The outlook will be monitored closely by AAA, QatarEnergy, and analysts including those at GasBuddy as conditions evolve.
