Gas Prices Surge: Causes, Trends, and Future Outlook

Gas Prices Surge to Four-Year Highs: Iran War, Refinery Disruptions, and What’s Next

May 4, 2026

Gas Prices Hit Wartime Highs as Iran Conflict and Refinery Issues Drive Costs

American drivers are paying the highest gas prices in four years, with the national average climbing to $4.39 per gallon—a 27-cent jump in a single week—as the ongoing war between Iran and the U.S.-led coalition disrupts global oil supplies and refinery operations falter. The latest spike follows a brief period of relief when prices dipped slightly during a two-week ceasefire in early April, but tensions have since reignited, sending crude oil prices soaring above $100 per barrel and keeping gas prices elevated.

The BP Whiting refinery in Indiana, the largest in the Midwest, remains a critical bottleneck. A lockout between BP and the United Steelworkers union—now in its second month—has reduced the refinery’s output, exacerbating shortages in the region. While BP continues to operate with temporary staff, the dispute has cut production by an estimated 440,000 barrels per day, forcing gasoline supplies to be rerouted from other refineries at higher costs.

Why Are Gas Prices So High? Three Key Factors

1. Iran War and Strait of Hormuz Disruptions

   • The conflict in the Middle East has blocked oil flows through the Strait of Hormuz, a critical chokepoint for global crude exports. Iran’s blockade, combined with U.S. Naval restrictions on Iranian oil shipments, has tightened global supply, pushing Brent crude to $90+ per barrel and WTI above $85.
   • Analysts warn prices could climb further if the war escalates, with some forecasting Brent crude nearing $120 per barrel if the Strait remains closed.

2. Refinery Outages and Labor Disputes

   • The BP Whiting refinery lockout is not the only issue: other U.S. Refineries have faced maintenance delays and labor shortages, reducing refining capacity just as demand rises.
   • In California, where prices have surged to $6.06 per gallon—the highest in the nation—local refineries are struggling to keep up with demand, forcing imports of pricier gasoline from other states.

3. Higher Global Oil Prices and Inflation Pressures

   • The World Bank forecasts a 24% surge in energy prices this year, the largest increase since Russia’s invasion of Ukraine in 2022. This has ripple effects across the economy, from transportation costs to consumer goods.
   • Americans spent $125 million more on gas last Friday alone compared to a week earlier, according to the Wall Street Journal, underscoring the financial strain.

• California remains the most expensive state, with prices 30% higher than pre-war levels.
• Illinois and the Midwest are particularly vulnerable due to refinery constraints, with some stations charging $4.50+ per gallon.
• Columbus, Ohio, has seen prices hover near $4.90, but experts predict modest relief if refinery operations stabilize.

When Will Prices Drop? Experts Offer Mixed Outlook

While the U.S. Energy Information Administration (EIA) forecasts a 6% decline in gas prices by year-end 2026, the near-term outlook remains uncertain:

• Short-term (May–June 2026):

  • Prices will likely stay above $4.00 per gallon unless the Iran conflict de-escalates or refinery disruptions ease.
  • The BP Whiting lockout could drag on, keeping Midwest prices elevated.

• Long-term (2026–2027):

  • The EIA predicts gasoline prices will average below $3 per gallon by year-end, the lowest since 2020, assuming oil prices stabilize.
  • GasBuddy’s 2026 outlook suggests Americans will spend $2,083 on gas annually, down from $2,500 in 2025.

What Can Drivers Do? Strategies to Save at the Pump

With no immediate relief in sight, here’s how to manage costs:

✅ Use price-tracking apps like GasBuddy or AAA to discover the cheapest stations. ✅ Avoid peak travel days—gas stations often raise prices on Fridays and Sundays. ✅ Consider electric vehicles (EVs) if possible: With electricity costs far lower than gas, long-term savings can be significant. ✅ Join a fuel rewards program (e.g., Costco, Flying J) for discounts of 5–10 cents per gallon.

Key Takeaways

• Gas prices are at their highest since 2022, driven by the Iran war, refinery issues, and global supply tightness.
• California ($6.06/gallon) and the Midwest ($4.10–$4.30) are hardest hit, but nationwide averages remain near $4.39.
• Prices may stabilize by late 2026, but short-term relief depends on geopolitical developments and refinery resolutions.
• Drivers should budget for higher costs and explore alternatives like EV charging or bulk fuel purchases.

What’s Next? Watch These Developments

• Iran-U.S. Ceasefire talks: Any progress could ease oil prices.
• BP Whiting refinery resolution: A labor deal could restore Midwest supply.
• Federal fuel reserves: The U.S. May release more strategic petroleum reserves to ease shortages.

For now, drivers should plan for continued high prices—but with careful shopping and long-term strategies, the financial pinch can be mitigated.
