HIGH IMPACT

When will gas prices go back down after the Iran war?

Quick answer: It depends on how long the Strait of Hormuz remains closed. If naval escorts resume shipping by late March, prices could ease within 2-4 weeks. If the blockade persists past April, elevated prices could last months.

The Key Variable: The Strait of Hormuz

Gas prices will not meaningfully drop until oil supply normalizes, and that hinges almost entirely on the Strait of Hormuz. About 20% of the world’s oil passes through this narrow waterway, which Iran has effectively blockaded since February 28.

Three Scenarios

Best Case: Prices ease by mid-April

If the US Navy begins escorting commercial ships through the strait by late March (as Energy Secretary Chris Wright suggested is possible) and/or a ceasefire is reached, oil prices could start falling within days. Gas prices typically lag oil by 1-2 weeks, so you could see relief at the pump by mid-April.

Middle Case: Elevated through summer

If the conflict drags on but partial shipping resumes through military convoys, oil prices may settle in the $90-110 range. Gas would stabilize around $3.50-4.00 nationally — higher than pre-war but not at crisis levels.

Worst Case: $5+ gas through 2026

If the strait remains fully blocked and the conflict escalates, oil could push toward $150-200/barrel. In this scenario, national gas averages could hit $5+/gallon, with California and other high-cost states seeing $6-7.

What Is Helping

  • IEA strategic reserve release: The largest coordinated release in history is adding supply
  • US domestic production: Already at record levels, with more wells coming online
  • Naval escort plans: G7 nations are coordinating convoy operations
  • Diplomacy: Both sides have expressed interest in ending the conflict, though conditions remain far apart

What You Can Do Now

  • Do not panic-buy or hoard fuel — that makes shortages worse
  • Combine trips and carpool when possible
  • Consider public transit if available in your area
  • If you are due for a car purchase, factor in fuel efficiency heavily
  • Lock in heating oil contracts if your provider offers fixed-rate plans
