The National and Oregon averages have been creeping up for the past month
PORTLAND, Ore., – Higher crude oil prices continue to fuel higher pump prices. Gas prices have been inching up since mid-July, after crude oil prices climbed into the upper $70s and low $80s per barrel. In the last month, crude prices have increased 9%. This has pushed the national and Oregon averages to their highest prices since last October. For the week, the national average gains four cents to $3.86. The Oregon average adds three cents to $4.69.
“Crude oil prices are up about 15% since July 1, driven in part by Saudi Arabia’s extension of its production cuts of one million barrels a day through September,” says Marie Dodds, public affairs director for AAA Oregon/Idaho. “Other factors are an increase in demand for gas in the U.S. and a decrease in gasoline supplies.”
Refinery output in the U.S. is back to normal levels. Earlier this summer, extreme heat across much of the U.S. led to refinery outages. When temperatures soar above 100 degrees, refineries can’t operate at peak levels. All refineries in the U.S. are at least 50 years old and many are more than 100 years old. They were not designed to operate in extreme heat. Plus, they’re processing an extremely flammable product.
Crude oil is trading around $81 today compared to $83 a week ago and $89 a year ago. In July, West Texas Intermediate ranged between about $69 and $82 per barrel. In June, WTI ranged between about $67 and $73 per barrel. In May, WTI ranged between about $63 and $77 per barrel. In April, WTI ranged between about $73 and $83. In March, WTI 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 47% of what we pay for in a gallon of gasoline is for the price of crude oil, 24% is refining, 14% distribution and marketing, and 14% are taxes, according to the U.S. Energy Information Administration.
Demand for gasoline jumped from 8.84 to 9.30 million b/d for the week ending August 4, according to the U.S. Energy Information Administration (EIA). This compares to 9.12 million b/d a year ago. Meanwhile, total domestic gasoline stocks decreased from 219.1 to 216.4 million bbl. Higher demand, amid tighter supply, has helped to keep pump prices elevated. If gas demand remains high, alongside increasing oil prices, drivers should brace for increases in pump prices.

The cheapest gas in the nation is in Mississippi ($3.32) and Louisiana ($3.43). For the 135th week in a row, no state has an average below $2 a gallon.
The difference between the most expensive and least expensive states is $1.85 this week, compared to $1.76 a week ago.
All 50 states and the District of Columbia have higher prices now than a month ago. The national average is 30 cents more and the Oregon average is eight cents more than a month ago. This is the smallest monthly increase in the nation. Oklahoma (+42 cents) has the largest monthly jump.

Idaho (-62 cents) has the largest yearly drop. Washington (+23 cents) has the largest year-over-year increase.
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.
| Rank | Region | Price on 8/15/23 |
| 1 | California | $5.17 |
| 2 | Washington | $5.03 |
| 3 | Hawaii | $4.79 |
| 4 | Oregon | $4.69 |
| 5 | Alaska | $4.48 |
| 6 | Nevada | $4.42 |
| 7 | Illinois | $4.17 |
| 8 | Utah | $4.16 |
| 9 | Idaho | $4.08 |
| 10 | Arizona | $4.08 |
As mentioned above, California has the most expensive gas in the country. Washington, Hawaii, Oregon, Alaska, and Nevada rounding out the top six. Arizona is 10th. Oregon is fourth for the 10th week in a row.
All states in the West Coast region are seeing week-over-week increases. Arizona (+16 cents) has the largest jump in the region. Hawaii (+1 cent) has the smallest.
The refinery utilization rate on the West Coast increased from 87.6% to 90.5% for the week ending August 4. This rate has ranged between about 73% to 96% in the last year. The latest national refinery utilization rate rose from 92.7% to 93.8%.
According to EIA’s latest weekly report, total gas stocks in the region increased slightly from 28.66 million bbl. to 28.78 million bbl.
A higher refinery utilization rate and an increase in gasoline stocks can put downward pressure on pump prices; however, the higher cost of crude oil means limited or no decreases in pump prices.
Oil market dynamics
Crude oil prices climbed above $84 per barrel last week, the highest price since mid-April 2023. Prices have increased amid market optimism that oil demand will be more robust than expected during this half of 2023 and into 2024. According to the Organization of the Petroleum Exporting Countries (OPEC), world oil demand is expected to rise by 2.25 million barrels per day (bpd) in 2024, compared with growth of 2.44 million bpd in 2023. Additionally, the EIA reported that total domestic commercial crude inventories increased from 439.8 to 445.6 million bbl.
