U.S. average retail diesel prices surpassed $5 per gallon on Monday for only the second time in history, according to data from fuel tracker GasBuddy. This significant price milestone was last reached in December 2022.
The primary driver for the current price surge is the ongoing conflict in the Middle East, which has severely impacted global supply chains. Iran's near-complete blockade of the Strait of Hormuz has directly affected 10% to 20% of the world's seaborne diesel supplies, while reduced crude flows have forced many Asian refineries to cut production, further tightening global availability.
Economists warn that elevated diesel prices could hinder global economic activity. As a key fuel for freight and manufacturing, higher costs are typically passed on to consumers, fueling inflation. In parallel, U.S. national average gasoline prices have also climbed, reaching $3.76 a gallon, the highest level since October 2023.
According to Patrick De Haan, head of petroleum analysis at GasBuddy, upward pressure on fuel prices is likely to persist until a significant resumption of oil flows through the Strait of Hormuz occurs.
Q: Why have U.S. diesel prices risen above $5?
A: Prices have surged due to severe disruptions in global supply chains caused by the conflict in the Middle East, a major producer of diesel and the crude oil used to make it.
Q: What was the previous record for diesel prices?
A: The only other time average U.S. diesel prices were above $5 was in December 2022, in the aftermath of Russia's invasion of Ukraine.
