Rising Gas Prices Linked to Iran Conflict
Crude oil price surges following recent strikes on Iran are driving up gasoline prices across the United States, with the national average exceeding $3 a gallon for the first time since December 1, 2025. The situation is being closely monitored as markets assess the potential impact on global energy infrastructure and access to vital shipping routes.
National Gas Price Increases
The national average for regular gasoline jumped 11 cents overnight, reaching $3.11 a gallon as of March 8, 2026 – a 16-cent increase for the week. This marks the highest price since October 2025. All 50 states are experiencing price increases [AAA]. The one-day spike is comparable to the 11-cent increase seen when Russia invaded Ukraine in March 2022, rising from $4.06 to $4.17 between March 7 and March 8.
Regional Variations
Oregon is experiencing a smaller week-over-week increase compared to other states, with the average rising four cents to $3.95 a gallon. This follows larger price jumps in Oregon and Washington last week due to an outage at the Olympic Pipeline. However, both states now show some of the smallest increases nationally [AAA].
Impact of the Iran Conflict
The surge in crude oil prices is a direct result of the weekend strikes on Iran by the U.S. And Israel [AAA]. The conflict is causing uncertainty regarding energy infrastructure and access to the Strait of Hormuz, a critical waterway for global oil transport. Approximately 20% of the world’s oil and refined products pass through the Strait of Hormuz [AAA].
Crude Oil and Gasoline Prices
Generally, a $1 increase in the price of crude oil leads to a 2.4- to 2.5-cent increase in the price of gasoline [AAA]. The current national average for regular gas is $3.25, a nearly 9 percent increase in the last week, or 27 cents per gallon [Car and Driver]. One month ago, the average was $2.89 per gallon [Car and Driver].
State-by-State Price Differences
Gas prices vary significantly by state. As of March 6, 2026, California has the highest average price at $4.81, followed by Washington at $4.44 and Hawaii at $4.43. The lowest prices are found in Oklahoma ($2.79), Mississippi ($2.81), and Kansas ($2.83) [Car and Driver].
Seasonal Factors
The increase in gas prices is likewise influenced by typical seasonal factors, including higher demand and the transition to summer-blend gasoline, mandated by the EPA to reduce air pollution [AAA].
Looking Ahead
The AAA anticipates that gas prices will continue to be affected by the ongoing conflict in Iran and its potential impact on global oil supplies. The situation remains fluid, and further developments could lead to additional price fluctuations.
