IEA Says Ukraine Drone Strikes Are Permanently Degrading Russia's Refining Sector
Persistent attacks on Russian refineries have pushed diesel exports to multiyear lows and global throughput nearly 5 million barrels a day below year-ago levels.
The IEA declared on September 11 (2026-09-11) that damage to Russia's refining sector is likely permanent in the near term, as sanctions block the equipment and expertise needed for repairs while Ukrainian forces have escalated to multiple drone waves against single sites to overwhelm air defenses. Russian oil refining output has been reduced to 4.69 million barrels per day, its lowest since 2009, the agency said.8,2
That assessment followed Ukraine's resumption of long-range drone strikes on oil refineries deep inside Russia on September 7 (2026-09-07), with plants in the Perm region and Tatarstan hit overnight, according to Rigzone. The attacks came immediately after US envoys visited Moscow and marked a return to a campaign that has been progressively dismantling one of Russia's most significant export industries.6
Russia's diesel and gasoil exports collapsed to just 80,000 barrels per day in the first seven days of August (2026-08-01 through 2026-08-07), the lowest reading in many years, Oilprice.com reported. That compares with exports of as much as 1 million bpd a year earlier. Moscow extended restrictions on diesel exports as it struggled to meet domestic fuel demand, and Russia — typically one of the world's largest diesel suppliers — was forced to import gasoline from Asia to avoid shortages.4,3
At the end of August (2026-08-31), Reuters reported that roughly 17% of Russia's oil-refining capacity had been at least temporarily taken out. Unconfirmed estimates cited in the Economist suggest the true figure may be closer to 40% affected, with around 20% offline at any one time. The higher figures have not been independently verified.1
The disruption is registering in global throughput data. The IEA's monthly Oil Market Report, published during the week of August 10 (2026-08-10), put global refinery crude throughputs at 80.9 million bpd in July, nearly 5 million bpd below year-ago levels. Throughputs are forecast to drop by 2.5 million bpd on average across 2026 before rebounding by 3.5 million bpd in 2027. Tighter light and middle distillate markets pushed cracks and margins in the Atlantic Basin to record highs, the IEA noted.4
Even a partial offset from US refiners has not closed the gap. US fuel exports rose by about 700,000 bpd in July from a year earlier, but global seaborne trade in petroleum products fell by 3.8 million bpd over the same period, driven by plunging exports from Russia and the Middle East, the IEA calculated. Brian Mandell, Executive Vice President of Marketing and Commercial at Phillips 66, told analysts on the company's second-quarter earnings call in early August that refining fundamentals were "very tight and getting tighter" given conditions in both regions.4,5
Nikhil Dubey, a senior research analyst at Kpler, said some Ukrainian drones appeared to have specifically targeted hydrocracker units — the refinery components central to diesel production. Precision targeting of that kind, if confirmed across multiple sites, would mean the damage is more structurally impairing than strikes on crude distillation units alone, which are simpler to repair or work around.3
Spot prices on Friday (2026-09-18) reflected a mixed picture. NYMEX heating oil front-month traded at $5.05 per gallon, down 1.37% on the session, while US diesel stood at $5.08 per gallon, off 0.97%. ICE Brent crude front-month held at $104.42 per barrel, down marginally. The day's softness in products sits in contrast with the supply warnings in the IEA's own report; the simplest explanation is that months of sustained coverage of the Russian refinery campaign has allowed markets to price in a substantial disruption premium already, with the IEA's forecasts pointing to conditions remaining tight well into 2027.
The IEA has said capacity elsewhere in the system is currently unable to offset product supply bottlenecks, and Middle East refining infrastructure has also sustained damage, compounding the shortfall.5,7
What product markets are watching now is how effectively Ukraine can maintain the tempo and precision of its strikes as Russia adapts its defenses. If the hydrocracker targeting strategy, flagged by Kpler, spreads to more facilities, the diesel supply impact could deepen beyond what current forecasts assume. Russia's ability to import refined products from Asia provides a limited buffer, but at volumes far below what its domestic refining system previously produced. With sanctions blocking repair parts and the IEA describing the degradation as persistent, the next monthly Oil Market Report will test whether the throughput deficit is stabilizing or widening further.8,3,4
