On October 9, the Treasury Department’s Office of Foreign Assets Control issued General License 135, authorizing transactions related to the sale, delivery and importation of Russian-origin diesel. That is an official change in what transactions are permitted; it is not proof that fuel has been shipped or delivered.

President Donald Trump said Russia would supply more than 300,000 metric tons immediately, followed by additional volumes in November and later. Those supply figures are an announcement, not independently confirmed deliveries. The Associated Press reported that energy experts questioned whether the plan would materially lower U.S. prices: Russian barrels could displace deliveries to other buyers rather than add equivalent supply to the global market. Diesel costs matter beyond the pump because trucking, farm equipment and freight networks use the fuel, but the size and timing of any pass-through to U.S. businesses or consumers remain uncertain. The development is distinct from prior coverage of fuel prices: the new fact is Treasury’s published authorization and the announced supply arrangement.

Will the Russian diesel announcement quickly lower U.S. fuel or grocery bills? There is no guarantee; deliveries are unconfirmed, and analysts expect any price effect to be limited or uncertain.
