Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices took a significant jump yet again this past week, with prices soaring over $0.30/gal higher than they were the week before. These price jumps were noticed across the board, as both the retail and wholesale rack markets saw significant price jumps. Part of this is due to the shortage of gasoline in the PNW, which has caused gas prices to climb over the last two weeks.
Drivers in the Portland area are still seeing gas around $4.93/gal & diesel over $5.61/gal. In Seattle, gas prices are $5.55/gal with diesel hovering around $6.55/gal.
The Trump admin has announced an “Economic D-Day” against Iran (after spending over $50 billion of US taxpayer dollars on this war), which will impose new sanctions and restrictions to Iran, as negotiations have ceased to continue between the U.S & Iran. So much remains unclear to the US public about the Iran war, such as why Jared Kushner, a non-elected private citizen and son-in-law of Donald Trump, is serving as a negotiator for the U.S in conversation with Iran.
WTI Crude is trading around $88.40/barrel as of the 25th. There have been no newly announced military strikes occurring within the last 17 days between the U.S & Iran. The 1-5 Corridor will have a planned 10 – 15 week shutdown of the 1-5 Corridor next to the Moda Center. This will begin September 9th 2026. We will provide more detail on this in the next Fuel Market Report. To learn more, go to Oregon – DOT.
Important Note: Per the City Of Portland, “Distributors in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they distribute beginning on May 15, 2024. All diesel fuel distributed to retail stations, non-retail dealers, or wholesale purchaser-consumers must include a minimum of 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on May 15, 2026, and 99% on May 15, 2030”.
Reasons For Price Variance
Crude oil is currently hovering, at a current price of $88.40/barrel.
Crude oil is the main ingredient for gasoline and diesel. Per AAA, on average about 50% of what you pay at the pump is the price of crude oil, breaking down as 25% refining, 11% distribution & marketing, and 14% taxes – a helpful breakdown for consumers wondering why they are paying the prices that they pay. Crude Oil is currently trading at $88.40/barrel compared to $85.37/barrel last week and $74 a year ago.
It’s essential to recognize that fuel prices result from a complex interplay of the factors mentioned above and other regional factors.
