Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices dropped this past week as tensions and conflict in Iran remained stagnant. The stagnation did not last as Iran announced negotiations did not continue, and they will return to a full blockade of the Strait of Hormuz. Upon this announcement, the US reinitiated its ground striking campaign in Iran with multiple strikes on Saturday & Sunday. The US reportedly struck military bases, radars, and drone sites in Tehran. The re-engagement of the conflict between Iran & The US has continued to choke the marine traffic throughout the Straight of Hormuz. Last week, only 36 ships passed through the waterway compared to 130/day before the conflict started.
Crude oil prices are skyrocketing on the heels of news over the weekend of the re-engaged military conflict in Iran. Fuel prices are expected to take a steep climb throughout this week as the conflict continues with no end in sight. The Trump Admin has proposed waiving the federal gas/diesel tax until September 2026. An act that would require approval by Congress. This proposal has signaled to many that the conflict in Iran will not be over anytime soon. This week, we will likely see crude oil prices back over $100/barrel.
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 $95/barrel, at a current price of $95.45/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 $95.45/barrel compared to $98.19/barrel last week and $75 a year ago.
