Russia Set to Extend Diesel Export Ban as Global Prices Hit Records and Oil Slips on Hormuz Diplomacy

Russia is preparing to extend its ban on most diesel exports beyond September 30, with people familiar with the matter saying an extension is already understood to be coming, with the only remaining question being whether it lasts one additional month or longer. Ukraine's ongoing drone strikes on Russian refineries are driving the decision, and a surprise attack on the Moscow refinery, which had reportedly been under repair since being heavily damaged in June and was not expected back online for six months, underscored the vulnerability of Russia's refining infrastructure.

Global diesel prices have already hit record highs as a result of the supply squeeze, and analysts warn further increases are possible. The pain is visible in corporate earnings: J.B. Hunt Transport Services warned that its earnings would fall 5% to 10% from the second to the third quarter, directly citing record diesel prices at roughly $6 per gallon, as truckers cannot raise freight rates fast enough to offset the fuel cost surge.

WTI crude oil, however, dropped sharply on September 21, settling at $95.78 per barrel after falling as much as 5.1%, its worst single-day drop since August 4. The selloff was driven by hopes that diplomatic talks on the sidelines of the UN General Assembly could ease tensions in the Middle East and by reports of resilient Saudi exports and larger oil flows through the Strait of Hormuz. Diesel spot prices also fell 17 to 27 cents per gallon on the day, and gasoline spots dropped 3 to 7 cents per gallon, offering near-term relief at the pump even as the structural diesel supply problem remained unresolved. The CBOE Volatility Index showed markets broadly shrugging off the geopolitical noise, with implied volatility remaining subdued despite the competing pressures.
