Russian oil refineries processed an average of 3.91 million barrels of crude per day in July 2026, the lowest monthly rate since March 2005, according to data from EA Analytics cited by Bloomberg. The figure represents a drop of more than 1.4 million barrels per day compared with the same period last year, and comes after a 100-day wave of Ukrainian strikes that hit at least 24 of the country’s 34 largest refineries. The capacity loss, estimated by a Russian economist at roughly one-third of total refining throughput, has severed the link between Russia’s status as a top crude producer and its ability to supply its own market with fuel.

The immediate cause is a sustained drone campaign that has shifted from export terminals to processing infrastructure deep inside Russian territory. In July, drones struck the Omsk refinery, Russia’s largest producer of gasoline, diesel and kerosene. Eight of the ten biggest refineries have been damaged, some knocked offline for weeks. Air defences have struggled to intercept the attacks, leaving repair crews racing to restore output. The result is a domestic gasoline deficit: production in June was 15 to 25 percent below year-earlier levels, while demand exceeded supply by roughly 20 percent, according to commodity analysts Kpler. Diesel and jet fuel are also affected, forcing airlines to cancel flights and the authorities to ban most diesel exports until the end of July.

The shortages are rippling across the economy and society. Over 50 regions have reported fuel bottlenecks, with prices spiking as much as 30 percent in a single week, according to the state statistics service Rosstat. In the southern agricultural belt—Rostov, Krasnodar and Stavropol—farmers are sleeping at petrol stations to secure rationed supplies for harvesters that consume up to 300 litres of diesel per shift; crop losses in Rostov could reach 15 percent. On the annexed Crimean peninsula, a state of emergency has been declared, electricity is rationed to six hours a day in Sevastopol, and gasoline is no longer sold to private individuals. The squeeze on shipping in the Sea of Azov, where Ukrainian drones struck 90 cargo vessels in one week, has further disrupted supply lines to the peninsula.

Viewed from Western capitals, the crisis exposes a vulnerability that sanctions alone did not achieve. While some international companies continue to operate in Russia—generating tax revenue that, according to the Atlantic Council, indirectly funds the war effort—the physical destruction of refining assets is directly curtailing the Kremlin’s ability to sustain both its military and civilian economy. President Vladimir Putin has acknowledged “certain problems with petroleum products” but said the situation would “gradually be corrected.” The next factual marker will be the July OPEC production report, which will show whether the drop in refining is also pulling down crude output, already at its lowest since at least February 2024.
