Gas prices in California have climbed as high as $6 per gallon as oil prices spiked ahead of a deadline set by President Trump for Iran to reopen oil trade routes in the Strait of Hormuz. Prices in the Southwest, which relies on California refineries, have also surged past $5 per gallon, with Nevada and Arizona reaching new records. Industry analysts warn that even if the Iran situation is resolved, it could take months for gas prices to return to more normal levels.

Why it matters

The sharp rise in gas and diesel prices is squeezing consumers and businesses across the Southwest, with the region's reliance on California refineries making it particularly vulnerable to global oil supply disruptions. Higher fuel costs will drive up the prices of transported goods, from groceries to online orders, impacting household budgets.

The details

California gas prices reached a high of $6 per gallon, with one motorist in Anaheim paying $44.09 for 7.35 gallons of regular gas. Nevada passed the $5 threshold, edging closer to its 2022 record of $5.68, while Arizona reached $4.75. Colorado remained below the national average at $3.81. The national average price of gas hit $4.14, up over a dollar from before the conflict with Iran started on February 28. Diesel prices have also surged, reaching a new record high of $5.65 per gallon nationally and $7.73 in California.

  • On April 8, 2026, California gas prices climbed as high as $6 per gallon.
  • On Tuesday evening, President Trump announced a two-week ceasefire with Iran.

What they’re saying

“In the Southwest, it's a little bit more of a dire straits situation when it comes to the prices at the pump.”

— Matt McClain, Petroleum Analyst, GasBuddy

“We are going to continue to see price increases irrespective of what happens tonight.”

— Matt McClain, Petroleum Analyst, GasBuddy

“Literally everything that we have on a store shelf arrives either by barge, by semi tractor trailer, or train – and all three of those utilize diesel to get from point A to point B. That factors into the end price that we consumers pay for everything – groceries, clothing, your favorite online store.”

— Matt McClain, Petroleum Analyst, GasBuddy

What’s next

If the Iranian government opens the Strait of Hormuz, relief at the pump could be slow, as it will take weeks or months for the large oil tankers to reach their destinations across the globe.

The takeaway

The sharp rise in gas and diesel prices in the Southwest, driven by global oil supply disruptions, is squeezing consumers and businesses, with the region's reliance on California refineries making it particularly vulnerable. Even if the Iran situation is resolved, it could take months for prices to return to more normal levels, further impacting household budgets and the cost of goods.
