PORTLAND, Ore., – The unexpected announcement from OPEC+ that it would cut oil production starting in May has helped push gas prices higher. Other factors behind climbing pump prices include an increase in demand for gas in the U.S. and a drop in gasoline stocks. For the week, the national average for regular unleaded jumps a dime to $3.61 a gallon. The Oregon average gains six cents to $3.99.

“Oil markets have had more than a week to digest the news from OPEC+. The announcement sent crude oil prices surging above $80 a barrel, although prices have struggled to stay above that mark,” says Marie Dodds, public affairs director for AAA Oregon/Idaho. “Still, the cost of oil accounts for more than 50% of what we pay at the pump, so drivers may not catch a break at the pump any time soon.”

On Sunday, April 2, the Organization of the Petroleum Exporting Countries and other major oil producers, including Russia, known collectively as OPEC+, announced a voluntary agreement to slash their output by just over 1 million b/d through the end of 2023. The cut is planned to start in early May. The move caused oil prices to spike, popping over the $80 per barrel mark. This puts upward pressure on pump prices when they were already rising due to the switch to summer-blend fuel and higher demand during the summer driving season.

Crude oil prices shot up above $80 per barrel on Monday, April 3 and remained above $80 last week. These were the highest closing prices since March 6. Crude oil continues to trade around $81 today compared to $81 a week ago and $94 a year ago. In March, West Texas Intermediate ranged between about $64 and $81 per barrel. In February, WTI ranged between about $73 and $80 per barrel. In January, WTI ranged between about $73 and $82 bbl. 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, 20% is refining, 11% distribution and marketing, and 14% are taxes, according to the U.S. Energy Information Administration.

Another factor putting upward pressure on pump prices this time of year is the seasonal switch to summer-blend fuel. California has an April 1 deadline to switch to summer-blend fuel, while the federally mandated deadline is May 1. The West Coast region often sees prices climb earlier than other parts of the country because of that earlier California deadline. More info on summer- and winter-blend gasoline can be found at the EPA website.

Demand for gasoline in the U.S. demand increased slightly from 9.15 to 9.3 million b/d for the week ending March 31. This compares to 8.56 million b/d a year ago. Meanwhile, total domestic gasoline stocks decreased substantially by 4.1 million bbl to 222.6 million bbl. Increased demand amid tighter supply has contributed to pushing pump prices higher. If demand continues to rise, pump prices will likely follow suit.

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 nation for the sixth week in a row. Hawaii Arizona, Washington, Nevada, and Oregon round out the top six. Alaska is eighth. Oregon is sixth for the ninth week in a row.

All states in the West Coast region are seeing small to moderate changes on the week. Arizona (+11 cents) has the largest increase in the region. Nevada (+1 cent) has the smallest weekly increase in the region. Hawaii (-1 cent) is the only state in the region with a weekly decline.

The refinery utilization rate on the West Coast fell from 86.0% to 82.7% for the week ending March 31. This rate has ranged between about 73% to 93% in the last year. The latest national refinery utilization rate is 90.3%.

According to EIA’s latest weekly report, total gas stocks in the region decreased from 30.12 million bbl. to 29.99 million bbl.

A lower refinery utilization rate and a decrease in gasoline stocks can put upward pressure on pump prices.

Oil market dynamics

Crude prices have remained between about $79 and $81 per barrel over the last week. Crude prices declined slightly to start this week on market concerns that a recession could occur this year, which could push oil demand and prices down. Last week, crude prices spiked after the Organization of Petroleum Exporting Countries and its allies, including Russia, collectively known as OPEC+, announced it would cut production by 1.6 million bbl starting next month for the remainder of 2023. Additionally, the EIA reported that total domestic commercial crude inventories decreased by 3.7 million bbl to 470 million bbl last week. 

U.S. markets were closed Friday in observance of Good Friday. At the close of Monday’s formal trading session, WTI fell 96 cents to close at $79.74. Today crude is trading around $81, compared to $81 a week ago. Crude prices are about $19 less than a year ago.
