Ukrainian drone strikes on refineries are the primary driver. Between January and May 2026, Ukraine doubled its strikes year-on-year, targeting 16 refineries and knocking out roughly 700,000 barrels per day of capacity . By July 2026, over 30% of Russia's operational refining capacity and more than 45% of its nominal capacity had been disabled, according to satellite imagery and thermal-infrared data analyzed by the Financial Times . Virtually all major refineries in central Russia were forced to halt or scale back output by May 2026 .
Multi-decade low refining output. By early July 2026, Russian gasoline production collapsed to about 65% of average seasonal consumption, while diesel output dropped to nearly the level of domestic demand . This production shortfall is the direct result of sustained damage that Moscow has been unable to repair fast enough.
Summer peak demand. The shortages coincided with the seasonal rise in fuel demand during summer, compounding the supply crunch .
Export bans. Russia imposed intermittent bans on gasoline exports starting in March 2024 and later banned diesel exports entirely in July 2026 as part of emergency stabilization measures . These bans have been extended multiple times, with the diesel export ban now in effect until January 2027 .
Record fuel imports from Belarus. In July 2026, gasoline and diesel shipments from Belarus to Russia hit a new monthly record — gasoline supplies from Belarusian refineries rose 13% over June to approximately 212,000 tons, while diesel shipments roughly doubled to about 162,000 tons . From January to July 2026, Belarusian gasoline supplies to Russia increased 25-fold .
Lower-quality fuel production. In August 2026, the Russian government temporarily slashed fuel quality standards, permitting the production, import, and sale of low-grade gasoline (classes K2–K4, corresponding to Euro-2 through Euro-4 standards) until July 1, 2027 — effectively reviving previously banned fuel grades to prevent a total collapse . Euro-2 gasoline had been banned in Russia since 2013 due to high sulfur content and other pollutants .
Other imports. Russia began importing petroleum products from foreign suppliers beyond Belarus, with Deputy Prime Minister Alexander Novak announcing a package of measures including import openings and the diesel export ban .
Refining margins. Analysts at Reuters noted that the Ukrainian strikes on Russian refineries and export facilities could enhance global refining profit margins, particularly for U.S. refiners, as Russian product exports are squeezed and global supply of refined products tightens . A report from the Oxford Institute for Energy Studies confirmed the strikes are changing the flow and composition of Russian oil exports, creating fuel shortages domestically while reshaping global product trade patterns .
Diesel supply pressure. With central Russian refineries that produce roughly 25% of Russia's diesel forced offline , and diesel output barely meeting domestic demand , Russian diesel exports have collapsed, contributing to tighter global diesel markets and upward pressure on diesel cracks (refining margins for diesel). Independent analysis by Kpler notes that lower Russian diesel exports continue to tighten Atlantic Basin middle distillate markets .
