Russia’s oil refinery output has dropped by over 60%, hitting its lowest level in 21 years since 2005, according to data from Energy Aspects (EA).Bloomberg, citing EA Analytics data, reported that Russia’s crude processing rate fell to 3.91 million barrels per day in July 2026, down more than 1.4 million barrels per day from the previous year’s average.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official.The outlet said EA Analytics gathers the data by “monitoring the entire crude supply chain, from satellite tracking of oil fields and storage tanks to real-time cargo flows,” adding that Moscow has classified official data and thus “making independent assessments of damage to the industry challenging.”The drop comes amidst Ukraine’s intensified strikes against Russian oil refineries nationwide in recent months.Ukraine’s General Staff claimed in early July that the strikes disabled 42.7% of Russia’s total projected oil refining capacity.Bloomberg, citing its own tally, reported that Ukraine has likely struck at least 24 of Russia’s 34 large refineries in 50 attacks over the past 100 days.The strikes included a July 6 attack on the Omsk refinery, Russia’s largest, which Bloomberg described as a key domestic fuel supplier, with Reuters confirming that the attack had forced the refinery offline.The months-long attacks led to an extensive fuel crisis in Russia and occupied Ukraine.Fuel rationing is reported nationwide across Russia, with locals complaining of queues and isolated confrontations between locals and law enforcement.
