Small Decline for National Average, Small Increase for Oregon Average

PORTLAND, Ore., – This is the time of year we often see a lull in demand for gasoline demand between spring break and Memorial Day, but oil markets remain volatile due to the conflicts in the Middle East and Ukraine. These are the major factors making gas prices waffle with small increases, some flat days and some price dips. For the week, the national average for regular edges down one cent to $3.66. The Oregon average adds seven cents to $4.50 a gallon.

“The switchover to the more expensive summer-blend fuel is wrapping up and we’re seeing smaller changes in gas prices this week. However, the big wildcard continues to be the price of crude oil, which accounts for more than half of what we pay for in a gallon of gas. Conflicts in the Middle East as well as the war between Russia and Ukraine continue to keep oil markets volatile,” says Marie Dodds, public affairs director for AAA Oregon/Idaho. “For now, the significant jumps in pump prices appear to be in the rearview mirror, barring unforeseen events.”

The national and Oregon averages remain at their highest prices since October. This week no Oregon counties have averages below $4 a gallon.

The Oregon average began 2024 at $3.79 a gallon compared to $4.50 today. Its lowest price so far this year is $3.58 on February 14. The national average started the year at $3.11 and is at $3.66 today. Its lowest price so far this year is just under $3.07 on January 15.

Gas prices always rise starting in late winter through the spring as refineries undergo maintenance as the switch to summer-blend fuel occurs. 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 make the change 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 until June 1. 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 as early as February.

Crude oil prices have remained elevated due to geopolitical events around the world including increased volatility in the Middle East, drone attacks on Russian refineries, and Houthi militant attacks in the Red Sea. In addition, production cuts by OPEC+ have tightened global crude oil supplies.

Crude oil prices have backed away from six-month highs. West Texas Intermediate climbed above $80 on March 14 and above $85 on April 2, then dipped below $85 starting on April 17. Major drivers of elevated crude prices are the unrest in the Middle East and the Ukrainian attacks on Russian refineries. Russia is a top global oil producer and the refinery attacks have reduced output.

Crude prices have been volatile after the attack on Israel by Hamas in October. While Israel and the Palestinian territory are not oil producers, concerns remain that the conflict could spread in the Middle East, which could potentially impact crude production in other oil-producing nations in the region.

Crude oil is trading around $82 today compared to $83 a week ago and $76 a year ago. In 2023, West Texas Intermediate ranged between $63 and $95 per barrel. Crude 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 oil is the main ingredient in gasoline and diesel, so pump prices are impacted by crude prices on the global markets. On average, about 56% of what we pay for in a gallon of gasoline is for the price of crude oil, 19% is refining, 10% distribution and marketing, and 15% are taxes, according to the U.S. Energy Information Administration.

Demand for gasoline in the U.S. is at its lowest level for April (except April 2020 during the COVID pandemic) since 2014. Demand for gas in the U.S. fell from 8.66 to 8.42 million b/d for the week ending April 19, according to the U.S. Energy Information Administration (EIA). This compares to 9.51 million b/d at the same time last year.

Meanwhile, total domestic gasoline stocks decreased by .6 million bbl to 226.7 million bbl.

Lower demand and a drop in oil prices could push pump prices lower.

California (+52 cents) has the largest year-over-year increase. Arizona (-68 cents) has the largest yearly decrease.

West Coast

The West Coast region continues to have the most expensive pump prices in the nation with all 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 ninth week in a row. Hawaii, Washington, Nevada, Oregon, Alaska and Arizona round out the top seven. Oregon is fifth most expensive for the 28th week in a row.

States in the West Coast region are seeing small week-over-week changes. Arizona (-9 cents), Nevada (-4 cents), and California (-3 cents) have weekly declines. Oregon (+7cents), Washington (+4 cents), Hawaii (+1 cent) and Alaska (+1 cent) have week-over-week increases.

The refinery utilization rate on the West Coast decreased from 86.5% to 84.6% for the week ending April 19. This rate has ranged between about 74% to 97% in the last year. The latest national refinery utilization rate increased slightly from 88.1% to 88.5%. 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.

According to EIA’s latest weekly report, total gas stocks in the region fell from 27.65 million bbl. to 27.46 million bbl.

An decrease in the refinery utilization rate and/or a low rate can put upward pressure on pump prices, and a dip in gasoline stocks can also put upward pressure on pump prices.

Oil market dynamics

Crude oil prices remained in the lower $80 range last week despite the EIA reporting crude oil inventories fell by 6.4 million barrels from the previous week. At 454 million barrels, U.S. crude oil inventories are 4% below the five-year average for this time of year. Crude prices dipped to start this week due to talks in Cairo over a possible ceasefire between Israel and Hamas.

At the close of Friday’s formal trading session, WTI added 28 cents to settle at $83.85. At the close of Monday’s formal trading session, WTI fell $1.22 to close at $82.63. Today crude is trading around $82 compared to $83 a week ago. Crude prices are about the same as a year ago.
