Gas prices are still moving lower in Oregon and three other West Coast states but are climbing in all other states, according to this week’s AAA report.
Crude oil prices have jumped to their highest in a month after a new string of attacks between the U.S. and Iran, a drop in shipping activity in the Strait of Hormuz, and market reactions to renewed fears of tightening global oil supplies. Earlier this month, West Texas Intermediate, the U.S. benchmark for crude, fell back to pre-conflict prices but is now back around $80 per barrel, the highest price since June 15.
Pump prices had been steadily decreasing since late May. The national average for regular gasoline jumps seven cents this week to $3.86 a gallon; the Oregon average loses five cents to $4.50 a gallon.
“Gas prices in Oregon and three other West Coast states haven’t started to increase yet. But with crude oil prices soaring, gas prices here and across the U.S. are poised to rise. Crude oil is the main ingredient used to produce gas and diesel, and when crude oil prices rise, pump prices usually follow suit,” says Marie Dodds, public affairs director for AAA Oregon/Idaho.
The Oregon average for regular gas began 2026 at $3.42 a gallon. The highest price of the year so far is $5.353 on May 20. The lowest price of the year so far is $3.33 on Jan. 20. The record high for the Oregon average is $5.548 set on June 15, 2022.
The Washington average for regular gas began 2026 at $3.86 a gallon. The highest price of the year so far is $5.789 on May 20, which is the record high for Washington. The lowest price of the year so far is $3.79 on Jan. 14.
The national average began 2026 at $2.83 a gallon. The highest price of the year so far is $4.564 on May 21. The lowest price of the year so far is $2.795 on Jan. 11. The record high for the national average is $5.016 set on June 14, 2022.
Oregon is one of just four states with lower gas prices this week. Ohio (+22 cents) has the largest week-over-week jump in the nation. Alaska (-6 cents), Oregon (-5 cents), Washington (-4 cents) and Hawaii (-2 cents) are the only states with week-over-week declines. The average in Michigan is flat.
Hawaii ($5.45) has the most expensive gas in the nation for the third week in a row; California ($5.38) is second. These are the two states with averages at or above $5 per gallon. This week there are seven states and the District of Columbia with averages at or above $4 a gallon, and 42 states have averages in the $3 range. No state has an average in the $2 range this week.
The cheapest gas in the nation is in Indiana ($3.22) and Texas ($3.41). No state has had an average below $2 a gallon since Jan. 7, 2021, when Mississippi and Texas were below that threshold.
The difference between the most expensive and least expensive states is $2.23 this week, compared to $2.41 a week ago.
Oregon is one of 47 states and the District of Columbia with lower prices now than a month ago. The national average is 22 cents less and the Oregon average is 50 cents less than a month ago – the second largest month-over-month drop in the nation. Washington (-54 cents) has the largest. Maryland (+3 cents) has the largest month-over-month increase.
All 50 states and the District of Columbia have higher prices now than a year ago. The national average is 71 cents more, while the Oregon average is 50 cents more. New Mexico (+$1.06) has the largest year-over-year jump in the nation. Indiana (+17 cents) has the smallest. The West Coast region continues to have the most expensive pump prices in the nation, with six of the seven states in the top 10.
As mentioned, Hawaii has the most expensive gas in the country for the third consecutive week. California, Washington, Alaska, Nevada and Oregon round out the top six. Arizona is 15th. Oregon slips to sixth most expensive after six weeks at fifth.
Four of the seven states in the West Coast region have week-over-week decreases and are the only states in the country with week-over-week declines: Alaska (-6 cents), Oregon (-5 cents), Washington (-4 cents), and Hawaii (-2 cents). Arizona (+3 cents), California (+1/2 cent), and Nevada (+1/2 cent) have week-over-week increases.
Oregon is one of 12 states and the District of Columbia with lower diesel prices this week. Florida (+45 cents) has the largest week-over-week jump. Michigan (-7 cents) has the largest week-over-week decrease, while Oregon (-7 cents) has the second-largest decline. For the week, the national average adds 11 cents to $4.88 a gallon.
