PORTLAND, Ore. – Gas prices are lower in all 50 states this week, with the national average price for regular gas falling below $4 a gallon for the first time since July 19, AAA Oregon/Idaho reported Tuesday. Oregon and Bend-area gas prices also have fallen, though still well above the U.S. average.

Seasonal factors are the major drivers of lower pump prices, including less expensive winter-blend fuel, the typical decline in gasoline demand we see this time of year, and refineries increasing output as refinery maintenance concludes. Lower crude oil prices below $90 per barrel are also putting downward pressure on pump prices.

For the week, the national average for regular gasoline plummets 17 cents to $3.98 a gallon. The Oregon average tumbles 15 cents to $4.62 a gallon, while Bend's drops 12 cents to $4.54.

The national average price for regular gas was last below $4 a gallon on July 19, when it was $3.99. It climbed a penny to $4.00 a gallon on July 20, and remained at or above $4 until Tuesday.

This 113-day stretch is the second-longest period at $4 or more per gallon on record. The longest stretch is 158 days from March 6 to August 10, 2022, after Russia invaded Ukraine. Earlier this year, the national average was at or above $4 a gallon for 79 days, from March 31 to June 17.

“Before this year, the national average had never gone above $4 a gallon in November. Drivers are finally getting some real savings at the pumps and that may spur some road trips by folks who were still on the fence about traveling for Thanksgiving,” says Marie Dodds, public affairs director for AAA Oregon/Idaho.

“But despite the declines, pump prices are still significantly more than a year ago, when the national average for regular gas was $3.07 and the Oregon average was $3.83.

Gas prices are significantly more expensive than they were before the conflict with Iran began. The National average for regular gas was $2.98 and Oregon average was $3.92 on Feb. 28, the day the U.S. and Israel launched airstrikes against Iran.

Crude oil prices remain volatile, with dramatic swings driven by concerns of how the conflict with Iran impacts global oil supplies. Since the conflict with Iran started, prices for West Texas Intermediate, the U.S. benchmark for crude, have ranged between $68 and nearly $113 per barrel. Crude was at $67 per barrel on Feb. 27, the day before the conflict began.

In general, every $1 increase in the price of crude oil leads to a 2.4- to 2.5-cent increase in the price of gasoline.

Attacks on ships in the Strait of Hormuz continue this month. October had the highest number of commercial shipping attacks in the Strait of Hormuz and surrounding waterways since the U.S.-Israeli conflict with Iran began in late February.

Normally, about 20% of the world’s oil and refined products flow through the Strait of Hormuz, which is the narrow passageway of the Persian Gulf and is bordered by Iran.

Tankers traveling through the Strait of Hormuz carry oil from major producers in the Middle East including Saudi Arabia, Kuwait, Bahrain, UAE, Qatar, Iraq and Iran. Any disruption in the straight can impact global oil supplies and send crude oil prices higher.

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 January 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 January 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 January 11. The record high for the national average is $5.016 set on June 14, 2022.

Demand for gasoline in the U.S. gasoline increased from 8.36 million barrels per day to 8.81 million for the week ending October 30. This compares to 8.87 million b/d a year ago. Total domestic gasoline supply decreased slightly from 209.2 million barrels to 209 million. Gasoline production increased from 9.24 million barrels per day to 9.70 million barrels.

In addition to the conflict in the Middle East, pump prices are also impacted by the normal seasonal factors. Gas prices usually drop in the fall, due to the switch from summer-blend to winter-blend fuel, which costs less to produce.

The switch starts in September. Many areas, including Oregon, can sell winter-blend fuel starting September 15. However, Northern and Southern California require summer-blend fuel through October 31. Prices usually decline to their lowest levels of the year in late fall and early winter before increasing again in the late winter and early spring.

This year, though, pump prices are elevated for this time of year due to all of the global geopolitical tensions.

Gas prices typically rise starting in mid-to-late winter and early spring as refineries undergo maintenance ahead of the switch to summer-blend fuel, which is more expensive to produce and less likely to evaporate in warmer temperatures.

The switch occurs first in California, which is why pump prices on the West Coast often rise before other parts of the country. The East Coast is the last major market to switch to summer-blend fuel.

Most areas have a May 1 compliance date for refiners and terminals, while most gas stations have a June 1 deadline to switch to selling summer-blend. Switch-over dates are earlier in California with some areas in the state requiring summer-blend fuel by April 1. Some refineries will begin maintenance and the switchover in February.

The U.S. price of crude oil (West Texas Intermediate) is below $90 to start this week. The conflicts in the Middle East, the war between Russia and Ukraine, and market concerns about global oil supplies continue to impact prices. Crude prices fell sharply earlier this summer as markets reacted to the peace deal between the U.S. and Iran.

WTI dipped below $70 for several days in late June and early July, the lowest prices since the start of the conflict. Crude prices rose again as the conflict escalated again. So far in November, WTI has ranged between about $97 and $88 per barrel.

WTI is trading around $87 Tuesday, compared to $96 a week ago and $60 a year ago. In 2025, West Texas Intermediate ranged between $80.04 (January 15) and $57.46 (October 16) per barrel. In 2024, WTI ranged between $66 and $87 per barrel.

In 2023, WTI ranged between $63 and $95 per barrel. WTI reached recent highs of $123.70 on March 8, 2022, shortly after the Russian invasion of Ukraine, and $122.11 per barrel on June 8, 2022. The all-time high for WTI crude oil is $147.27 in July 2008.

Crude prices are determined in international markets, based on global supply and demand, and are impacted by economic news as well as geopolitical events around the world including the conflict with Iran and disruptions in the Strait of Hormuz and the Red Sea, economic uncertainty, the situation in Venezuela, tensions over Greenland, sanctions on Iran’s oil, the conflict between Israel and Hamas, and the war between Russia and Ukraine. Russia is a top global oil producer, behind the U.S. and Saudi Arabia.

Crude oil is the main ingredient in gasoline and diesel, so pump prices are impacted by crude prices on the global markets. On average, about 50% of what we pay for in a gallon of gasoline is for the price of crude oil, 24% is refining, 13% distribution and marketing, and 13% are taxes, according to the U.S. Energy Information Administration.

Meanwhile, crude oil production in the U.S. remains at or near record highs. The U.S. Energy Information Administration (EIA) reports that crude production in his country is at 14.00 million barrels per day for the week ending October 30. Production has been at 13.5 million barrels per day many times since October 2024. The U.S. has been the top producer of crude oil in the world since 2018 and has been increasing its oil production since about 2009.

Quick stats

All 50 states and the District of Columbia have lower gas prices this week. Michigan (-39 cents) has the largest week-over-week decrease in the nation. The District of Columbia (-4 cents) has the smallest.

California ($5.71) has the most expensive gas in the nation for the 17th week in a row. The cheapest gas in the nation is in North Carolina ($3.24)

There are three states with averages in the $5-range, 18 states and the District of Columbia with averages at or above $4 a gallon, and 29 states with averages in the $3-range. No state has an average in the $2 range this week.

No state has had an average below $2 a gallon since January 7, 2021, when Mississippi and Texas were below that threshold. At the time, the COVID-19 pandemic drove significant declines in crude oil and gasoline demand in the U.S. and around the world.

All 50 states and the District of Columbia have lower prices now than a month ago. The national average is 39 cents less and the Oregon average is also 39 cents less than a month ago. North Carolina (-84 cents) has the largest month-over-month decline. Hawaii (-1 cent) has the smallest.

All 50 states and the District of Columbia have higher prices now than a year ago. The national average is 91 cents more, while the Oregon average is 79 cents more than one year ago. Nebraska (+$1.21) has the largest year-over-year jump in the nation. North Carolina (+43 cents) has the smallest.

West Coast

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. It’s typical for the West Coast to have six or seven states in the top 10 as this region tends to consistently have fairly tight supplies, consuming about as much gasoline as is produced. In addition, this region is located relatively far from parts of the country where oil drilling, production and refining occurs, so transportation costs are higher. And environmental programs in this region add to the cost of production, storage and distribution.

As mentioned above, California has the most expensive gas in the country for the 17th consecutive week. Hawaii, Nevada, Washington, Oregon, and Alaska round out the top six. Arizona is 14th. Oregon is fifth most expensive for the sixth week in a row.

All seven states in the West Coast region have week-over-week decreases: Washington (-19 cents), Nevada (-18 cents), California (-18 cents), Arizona (-18 cents), Alaska (-17 cents), Oregon (-15 cents), and Hawaii (-4 cents).

The refinery utilization rate on the West Coast fell from 95.1% to 91.7% for the week ending October 30. This rate has ranged between about 71% to 95% in the last year. The latest national refinery utilization rate rose from 92.8% to 94.5%.

The refinery utilization rate measures how much crude oil refineries are processing as a percentage of their maximum capacity. A low or declining rate can put upward pressure on pump prices, while a high or rising rate can put downward pressure on pump prices.

According to EIA’s latest weekly report, total gas stocks in the region ticked down from 27.57 million bbl. to 27.26 million bbl. for the week ending October 30. An increase in gasoline stocks can put downward pressure on pump prices, while a decrease in gasoline stocks can put upward pressure on pump prices.

Oil market dynamics

Crude oil prices fell below $90 per barrel to start this week, on hopes of diplomacy between the U.S. and Iran, and that further U.S. strikes on Iran are less likely if negotiations progress. Expect oil prices to continue to be volatile, depending on developments in the Middle East, as well as impacts of Ukrainian drone attacks on Russian refineries.
