Ukrainian Drone Campaign Cuts Russian Refining Capacity to 16-Year Low as Dual Supply Shock Sustains Oil Above $110
Six major refineries forced offline in May as systematic infrastructure strikes compound Strait of Hormuz disruption, creating unprecedented supply pressure.
Ukrainian drone strikes have driven Russia’s oil refining capacity to its lowest level since December 2009, with six major facilities forced offline in May alone as a coordinated campaign targets energy infrastructure during peak demand season.
Russia’s average refinery throughput fell to 4.69 million barrels per day in May, according to 19FortyFive. Ten major refineries were struck this month, with facilities in Moscow, Ryazan, Perm, Kirishi, and Samara shut down alongside the indefinitely closed Tuapse complex. The disruption has knocked out facilities processing 83 million metric tons annually — equivalent to 238,000 tons per day.
Escalating Infrastructure Campaign
The May offensive represents a sharp acceleration in Ukraine’s targeting of Russia’s energy sector. On May 18-19, strikes hit the Lukoil-Nizhegorodnefteorgsintez refinery in Kstovo — a facility processing 17 million tons annually — while separate attacks damaged the Yaroslavl-3 oil pumping station, destroying four storage tanks totaling 140,000 cubic meters, per Ukraine Today.
“Refineries in Moscow, Ryazan, Perm, Kirishi, and Samara are down. Tuapse is indefinitely closed. Primorsk and Yaroslavl were also stopped in May.”

The campaign’s impact extends beyond headline capacity losses. Ukrainian long-range strikes have reduced Russia’s oil refining by 10% in the first five months of 2026, according to Ukrainska Pravda. More significantly, at least one Russian oil company has been forced to shut down approximately 400 producing wells — a development President Volodymyr Zelenskyy described as particularly damaging given the nature of Russian oil extraction.
Compounding Global Supply Shock
The Russian refining crisis arrives amid existing supply constraints from the effective closure of the Strait of Hormuz since February 28. That crisis — triggered by the escalating Iran-Israel conflict — has disrupted 20% of global oil supplies through the world’s most critical energy chokepoint. Combined, the two disruptions have removed an estimated 2.9 million barrels per day of refining capacity, according to Energy News Beat.
Brent crude traded at $111.22 per barrel on May 19, down from the April peak of $138 but still elevated well above pre-crisis levels. The US Energy Information Administration forecasts Brent averaging $106 through the second quarter, with meaningful price relief contingent on normalisation of Strait flows.
The Strait of Hormuz typically handles 21 million barrels per day — roughly one-fifth of global oil consumption. Its closure represents what IEA Executive Director Fatih Birol called “the largest supply disruption in the history of the global oil market.” The simultaneous degradation of Russian refining capacity creates a dual shock with limited spare capacity buffers in global markets.
Strategic Implications for Moscow
The refining disruption strikes at multiple revenue streams simultaneously. Beyond immediate processing losses, the campaign forces well shutdowns that complicate future production recovery and damages export infrastructure critical to federal budget revenues. Russia’s refining capacity is expected to remain below 5 million barrels per day through June, with the International Energy Agency forecasting recovery to only 5.4 million bpd by late 2026, per UNITED24 Media.
Zelenskyy framed the campaign as “Ukrainian long-range sanctions” that are demonstrably working. “Given the nature of Russian oil production, this is what hurts them most,” he stated, signalling intent to expand operations targeting energy infrastructure.
What to Watch
Track diplomatic progress on Strait of Hormuz reopening negotiations — any breakthrough would ease one pressure point but leave Russian refining constraints in place. Monitor whether Ukraine expands strikes to upstream production facilities or focuses on maintaining pressure on existing damaged refineries. Watch Chinese and Indian crude import data for May, as these buyers typically absorb discounted Russian barrels that Moscow can no longer refine domestically. Finally, observe whether sustained $110+ oil triggers demand destruction in major importing economies, particularly in Asia and Europe where growth is already fragile. The dual supply shock creates conditions where geopolitical developments in either theatre — Ukraine or the Gulf — can trigger rapid price movements in either direction.
