US Diesel Hits Record $6.51 a Gallon as Russia Extends Export Ban and Global Fuel Crunch Deepens

The national average price of diesel in the United States surged to a record $6.51 per gallon as of September 21, according to AAA data, up from roughly $6 a gallon just two weeks earlier and more than 75% above the $3.70 average one year ago. California topped $8.42 per gallon. In Europe, French diesel prices crossed €2.40 a litre as the fuel crisis spread across global markets.

The price spike reflects a convergence of supply disruptions. Middle East energy flows remain heavily constrained, Brent crude oil holds around $100 per barrel, and Russia is now set to extend its ban on most diesel exports beyond the end of September, with sources saying it could last another month or more. Ukraine's continued drone strikes on Russian refining infrastructure, including a fresh hit on the Moscow refinery that had only recently resumed primary distillation after a prior June attack, are preventing any near-term recovery in Russian output.

Oil prices themselves pulled back sharply on September 21, with WTI crude settling at $95.78 per barrel, down about 5.1% on the day, its worst single-session loss since August 4. The selloff came on reports of larger crude flows through the Strait of Hormuz and hopes that diplomatic talks on the sidelines of the UN General Assembly could ease tensions. Diesel spot prices fell 17 to 27 cents per gallon on the day, offering the prospect of some retail price relief ahead, while gasoline spots dropped a more modest 3 to 7 cents.

The fuel crunch is already hitting corporate earnings. Trucking giant J.B. Hunt has warned of a meaningful earnings decline, with its CFO citing at least a $10 million fuel cost headwind and describing some of the most extreme fuel price swings the company has ever experienced. Supertanker shortages have simultaneously driven oil shipping rates up roughly 258% over two months, adding another layer of cost to global supply chains. A commodity strategist cited in coverage of the record diesel print warned that no diplomatic handshake can quickly replace the lost supply volumes.
