Global oil and US gas prices are persistently high, even though traffic is flowing again in the Strait of Hormuz. Prices eased over the summer after the United States and Iran signed a peace plan to end the war in June, but an escalation in military action in late August reversed that decline.

Unblocking the Strait of Hormuz has been helpful, but it’s still incredibly dangerous — and thus expensive. Not only that, but Russian refineries are getting destroyed by Ukrainian drones and Houthi attacks in the Red Sea have disrupted a vital shipping lane.

Gasoline prices have never been this high at this time of year, according to AAA data.

US gas prices are back above an average $4 a gallon. In June, after the peace plan was signed, gasoline prices dropped below the $4 threshold for the first time since March 30, according to the AAA, but that trajectory has now changed course.

The US national average diesel price is hovering near a record high, according to AAA data.

Gasoline prices reached their highest level in more than three years in the early stages of the war with Iran, before dropping off after the June peace plan was signed. Prices have begun to climb again amid renewed hostilities.
