Gas Prices Climb as Middle East Tensions Spike—See Which States Are Cheapest and Most Expensive

Key Takeaways

• Gas prices have surged across the U.S. this week as oil prices have jumped amid a widening Middle East conflict that threatens supplies.
• The national average is now $3.48, with only four states’ averages remaining under $3—while California drivers are paying more than $5.
• After falling below $3 in December for the first time since 2021, the national average stayed there for 13 weeks before shooting up.

U.S. Gas Prices Climbed Quickly This Week, Rising Above $3.30

Oil prices have climbed steeply as the Iran war fuels fears of supply disruptions, and the impact has quickly shown up at the pump. The national average for regular gas has surged 50 cents a gallon in eight days, rising from $2.98 on Feb. 28 to $3.48 today.

Prices first breached the $3 mark on March 1, after holding below that level for 13 straight weeks—the first sustained stretch in $2 territory since 2021. But since then, the national average has climbed every day for over a week as the Middle East conflict escalates and oil prices rise.

Because gasoline prices tend to track crude, the rally in energy markets has quickly filtered through to drivers.

Why This Matters

Gas prices are jumping higher, which could affect commuting and travel budgets if the trend continues. Still, what you pay depends heavily on your state—and the gap can be more than $2 per gallon.

Where Gas Is Cheapest—And Most Expensive—Right Now

Gas prices vary sharply depending on where you live. While the average has surged everywhere, state-level prices still span a wide range across the country.

As of March 9, drivers in Kansas, Oklahoma, Missouri and Arkansas are the only ones seeing an average price below $3.00 per gallon, according to AAA.

At the other end of the spectrum, Washington, Hawaii, Nevada, and Oregon all have statewide averages above $4.00—and California’s average has shot up to $5.20 per gallon. That’s more than a $2 gap between the priciest and cheapest states.

Western states typically see higher prices because of fuel taxes, environmental regulations, and supply constraints. With oil prices rising amid the Iran war, those regional differences are now layered on top of broader upward pressure at the pump.

The Last Time Gas Hit $5

The national average briefly topped $5 per gallon in June 2022. Amid this week’s surge, California’s average is now above that mark—though most states still have averages in the $3 range.

Why Gas Prices Vary So Widely by State

The differences in state pricing can be striking. But the spread isn’t random—it reflects structural differences in how gasoline is taxed, produced, and delivered across the country.

Fuel taxes are one of the biggest reasons prices vary by state, according to the U.S. Energy Information Administration. In 2023, federal and state taxes accounted for more than 14% of the average price per gallon. Because some states add far more in taxes and fees than others, those differences show up clearly at the pump.

Prices also depend on proximity to refineries and pipelines, as well as whether a state requires special fuel blends that cost more to produce. California, for example, mandates a unique, cleaner-burning gasoline blend that relatively few refineries produce. The state also has one of the highest gasoline taxes in the country.
