Ukraine’s Drone Campaign Drives Russian Oil Output to One-Year Low

In May 2026 Russia’s crude output fell to 9.009 million barrels per day (bpd), the lowest level in a year and down from the November 2025 peak of 9.38 million bpd. The drop leaves output about 690,000 bpd beneath the ceiling set for Russia under the OPEC+ agreement.

Ukrainian forces launched at least 31 drone strikes on Russian refineries, export terminals and pipelines in May—the highest monthly total since the invasion began. A fire at Afipsky Oil Refinery in Krasnodar Krai on 11 June followed a drone hit. Unmanned Systems commander Robert Brovdi said Ukraine aims to isolate Crimea, noting a 71 % drop in cargo traffic on R-280 “Novorossiya” highway. Ukrainian drones struck 180,000 Russian military targets in May and intercepted 4,000 Shahed-type drones.

OPEC reported May output of 9.009 million bpd, about 690,000 bpd under the OPEC+ ceiling for Russia. The International Energy Agency recorded April output near 8.8 million bpd, a 460,000 bpd year-on-year decline, attributing the fall to damage at refineries. Bloomberg notes that Russian crude-processing rates in June hit their lowest level in two decades.

Robert Brovdi, commander of Ukraine’s Unmanned Systems Forces, told Reuters, “We will isolate Crimea in the near future” and added, “Within another month, we will have total control over the road.” Commander-in-Chief Oleksandr Syrskyi posted that Ukrainian drone units struck nearly 180,000 Russian military targets in May, a 12.7 % rise. Deputy Prime Minister Alexander Novak said production fell “below where they stood in early 2026” because of “unscheduled maintenance” at several refineries. Kyiv maintains the strikes aim to curb Moscow’s war financing.

Russian officials attribute the output drop to unscheduled maintenance, while Ukrainian and independent analysts link it to drone-induced damage that has taken more than 10 % of national refining capacity offline. OPEC cites 9.009 million bpd for May; the IEA records 8.8 million bpd for April, highlighting a data gap.

The energy sector provides a major share of Russia’s export revenue, so reduced output strains war-time financing. Moscow has responded by raising crude exports to levels not seen since 2022 and by banning jet-fuel exports on 1 June to protect supply. Persistent shortfalls could prompt OPEC+ members to revise output targets, reshaping global oil supply and prices.
