US Gasoline Prices Rise as Mideast Tensions and Tight Supply Lift Crude Oil

U.S. gasoline prices have reversed their recent decline, rising sharply this week as geopolitical tensions in the Middle East drove crude oil to its largest weekly gain in eight weeks. The national average price for a gallon of gasoline climbed 6 cents to $3.88 on Friday, the biggest weekly jump since mid-May, according to data from AAA.

Geopolitical Tensions Drive Crude Higher

The primary driver for the increase is a surge in crude oil prices following renewed conflict between the U.S. and Iran. Attacks on several oil tankers in the Strait of Hormuz, a critical waterway for global energy supplies, prompted retaliatory strikes and heightened market fears of a wider disruption.

As a result, the global oil benchmark Brent crude was on track for a weekly gain of approximately 5.5%. "Gasoline prices have rallied alongside the massive move higher in crude oil after several tankers in the Strait of Hormuz were attacked," said Alex Hodes, director of energy market strategy at brokerage StoneX.

Constrained Supply Adds to Pressure

Beyond the rise in crude, tightening fuel supplies are also contributing to higher prices at the pump. A series of unplanned refinery outages in both the U.S. and Russia has constrained the production of refined products like gasoline.

Key factors tightening the market include:

• Falling U.S. Inventories: U.S. gasoline stockpiles fell by 1.9 million barrels last week to 212.1 million barrels, nearly 10 million barrels below the five-year average, according to the Energy Information Administration (EIA).
• Strong Export Demand: U.S. refiners are exporting fuel at a record pace to meet global shortfalls, with petroleum product exports hitting a weekly record of 8.7 million barrels per day in the week ending July 3, EIA data showed.
• Domestic Refinery Disruptions: Recent outages include Marathon Petroleum’s refinery in Detroit and Delta’s refinery in Trainer, Pennsylvania, further limiting domestic supply.

Political and Consumer Impact

The return of high gasoline prices is a significant issue during the peak U.S. summer driving season and has become a political concern for the Trump administration ahead of November's midterm elections. President Trump has accused oil companies of price gouging and urged the Justice Department to investigate, while also promoting localized price-cutting initiatives.

Analysts suggest the combination of geopolitical risk and tight fundamentals will keep prices volatile. "It seems prices will mostly drift up and down here in the short-term," said Denton Cinquegrana, chief oil analyst at Dow Jones Energy.
