Pain at the Pump Worsens
The national average price of regular gasoline reached $4.09 per gallon on April 3, 2026, according to AAA, representing a 37% increase from the $2.99 average on February 27, the day US military operations against Iran commenced. The surge is the fastest sustained gasoline price increase since the 2022 spike following Russia's invasion of Ukraine.
Crude oil prices have been the primary driver, with West Texas Intermediate (WTI) trading at $98.40 per barrel and Brent crude at $102.60. Both benchmarks have risen more than 45% since the conflict began, fueled by supply disruption fears centered on the Strait of Hormuz.
State-by-State Snapshot
Prices vary significantly by region, with West Coast states continuing to pay the highest prices:
- California: $5.47/gallon (highest in nation)
- Hawaii: $5.21/gallon
- Washington: $4.89/gallon
- Nevada: $4.67/gallon
- Oregon: $4.52/gallon
- National average: $4.09/gallon
- Mississippi: $3.52/gallon (lowest in nation)
- Texas: $3.61/gallon
- Oklahoma: $3.58/gallon
The Strait of Hormuz Factor
The single biggest risk to oil markets is the potential closure of the Strait of Hormuz, the narrow waterway between Iran and Oman through which approximately 21% of global oil supply transits daily. Iran has repeatedly threatened to close the strait in retaliation for US attacks, and has already conducted provocative actions including boarding a commercial tanker on March 28.
"A full closure of the Strait of Hormuz would be the most significant oil supply disruption in history," said Helima Croft, head of global commodity strategy at RBC Capital Markets. "We are talking about removing 17-18 million barrels per day from the market. Prices would go to $150 or higher almost immediately."
The US Fifth Fleet has reinforced its presence in the Persian Gulf with two carrier strike groups and additional mine countermeasure vessels, but the narrow geography of the strait makes it inherently difficult to defend against Iranian mines, fast attack boats, and shore-based anti-ship missiles.
Economic Impact
Rising gas prices are functioning as a regressive tax on American households, with the greatest burden falling on lower-income families who spend a larger share of their income on transportation. The average American household is now spending approximately $220 more per month on gasoline compared to before the conflict.
The price surge is also feeding into broader inflation concerns. The Federal Reserve, which had been signaling potential rate cuts in 2026, has adopted a more cautious stance. Fed Chair Jerome Powell noted in his March testimony that "energy price developments represent a significant upside risk to the inflation outlook."
Government Response
The Biden administration has released 30 million barrels from the Strategic Petroleum Reserve since the conflict began and has called on OPEC+ members to increase production. Saudi Arabia has indicated it could boost output by 1 million barrels per day within 90 days, but so far has not committed to doing so.
Congressional proposals to suspend the federal gas tax of 18.4 cents per gallon have gained bipartisan support but face opposition from transportation advocates who warn that the Highway Trust Fund is already underfunded.
Price Forecast
Energy analysts project that gas prices could reach $4.50-$5.00 nationally by summer if the conflict continues and the Strait of Hormuz remains under threat. A full closure of the strait could push prices above $6.00, a level that economists say would significantly increase recession risk.
For now, drivers are adjusting by consolidating trips, using gas price comparison apps, and in some cases switching to public transit. Electric vehicle sales have surged 35% month-over-month, suggesting the crisis is accelerating the transition away from gasoline dependence.
