Russia Announces Short-Term Diesel Export Ban, Sending Global Fuel Prices to Multi-Year Highs

Russia has officially implemented a three-week ban on all diesel exports. As the world's second-largest diesel exporter, Russia accounts for 11% of the global diesel supply. The restrictive policy directly pushed European diesel crack spreads to jump over $60 per barrel, marking a record high since 2011. The immediate trigger for the ban was continuous deep strikes on Russia's refining system by Ukrainian drones. Following damage to several core refineries, Russia's crude processing rate plunged to a multi-year low, causing the domestic supply gap to widen rapidly.
