Portland Retail Fuel Price Variance

Fuel Market News
Fuel prices were mostly stagnant this past week, with only a $0.02/gal variance on both the wholesale rack market and the retail market. Crude Oil prices are currently hovering around $110/barrel. President Trump has once again delayed planned strikes on Iran while also extending Russian sanction waivers for “vulnerable countries”. This allows given countries to buy Russian oil and refined products until June 17th.
The continued hostility between the US & Iran along with higher crude prices has cost US consumers an estimated $45 billion since the beginning of the war, with no end in sight. The conflict continues to draw bipartisan disapproval as goals and timelines of the war remain extremely murky. A global oil shortage is continuing to grow with an estimated 1 billion barrels in production lost by the end of May. The IEA has warned that demand for oil will exceed supply in 2026 with a daily loss of production exceeding 3.9 million barrels. Analysts across the globe are factoring a prolonged oil shortage and its lasting effects on supply and demand into the 3rd quarter of 2026.

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”.
Crude oil is hovering just above $110/barrel, at a current price of $111.50/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 $115.50/barrel compared to $102.60/barrel last week and $77 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.
