A Ukrainian drone strike damaged the Moscow refinery on Sept. 20, hitting the AVT-6 primary refining unit and an integrated crude-processing unit, according to Ukraine’s General Staff. The facility, owned by Gazprom Neft, processes about 245,000 barrels of crude a day, or roughly 12 million metric tons annually, producing gasoline, diesel, aviation fuel and fuel oil. The attack came as disruptions in the Middle East and Russia strained global diesel supplies. Bloomberg data showed global diesel futures and refining margins at record highs, while the U.S. retail diesel price reached $6.45 a gallon. The crisis has intensified debate in Washington over restricting or banning U.S. diesel exports, although analysts and research institutions warn that such a move could reduce domestic refinery activity and worsen global fuel shortages.
