Ukraine strikes Russian oil refineries in August, pushing refining output to 20-year low

Ukraine’s Defense Ministry announced that its forces struck 12 large Russian oil refineries in August, part of a broader campaign that saw at least 21 recorded attacks on Russian refining infrastructure during the month. That figure represents the highest monthly total since Russia launched its full-scale invasion of Ukraine.

The result has been dramatic. Russian oil refining volumes dropped to approximately 3.8 million barrels per day, a level the country hasn’t seen in more than two decades.

The scope of the damage

The strikes weren’t scattered potshots at minor facilities. Ukraine’s drone campaign targeted some of Russia’s most significant refining operations, including four of the country’s ten largest refineries.

Facilities at Kirishi (the KINEF plant), Nizhny Novgorod, and Volgograd were among those severely affected. Some plants endured repeated hits: the YANOS refinery, for instance, was targeted multiple times throughout 2026.

Ukraine’s military has framed these operations under its “Deep Strike” doctrine, using long-range drones to reach targets hundreds of kilometers inside Russian territory.

Russia’s fuel crunch by the numbers

The downstream effects on Russia’s fuel supply have been severe. Gasoline production fell nearly 20% compared to the same period last year during the first three weeks of August. Diesel output dropped even more sharply, declining over 23% year-over-year in the same window.

Refinery repairs take months, sometimes longer, especially under sanctions that restrict access to specialized equipment and spare parts from Western manufacturers. Meanwhile, Ukraine keeps hitting the same facilities, resetting the repair clock each time.

Strategic logic and global market implications

Ukraine’s targeting strategy serves a dual purpose. The obvious military objective is to degrade Russia’s ability to fuel its war machine. Tanks, armored vehicles, and logistics trucks all run on refined fuel, not crude oil. The second objective is economic pressure. Domestic fuel shortages force Moscow into uncomfortable policy choices: restrict exports to keep domestic prices stable (losing revenue), or maintain exports while rationing fuel at home (losing public support).

Oil prices have already reflected some of this geopolitical risk premium, though the market’s reaction has been moderated by softening demand forecasts in parts of Asia.
