All 50 states top $4 a gallon gas as Iran war impacts linger

Why It Matters

For the first time, every U.S. state is averaging above $4 a gallon at the pump, a milestone that reflects the sustained economic strain from ongoing military conflict with Iran. The rising fuel costs are squeezing household budgets, cutting into small business margins, and pushing broader inflation higher across the country.

What Happened

AAA reported Wednesday that the national average for a gallon of regular gasoline has climbed to $4.56, with seven states now exceeding $5 a gallon. California leads the nation at $6.15 per gallon, while Georgia sits at the low end at $4.01. Several southern states had been holding just below the $4 threshold in recent days before crossing it.

Fuel prices have surged 53% since hostilities with Iran began, now approaching the three-month mark. The spike is directly tied to disruptions in global oil supply chains, particularly the status of the Strait of Hormuz. If that critical waterway remains closed into mid-summer, GasBuddy analyst Patrick De Haan warned Wednesday that the national average could breach $5.03 per gallon — an all-time record.

What’s Next

Analysts will be closely watching developments in the Strait of Hormuz as the primary driver of further price increases. Any prolonged closure would accelerate the path toward record-breaking pump prices. The energy sector is also undergoing structural shifts domestically — a proposed merger between NextEra and Dominion could reshape U.S. power infrastructure at a moment when energy security is front of mind for policymakers and consumers alike.
