The International Energy Agency just took a red pen to its Russian oil forecasts, and the numbers tell a stark story. The IEA cut its 2026 Russian crude output projection by 125,000 barrels per day to 8.7 million bpd, while slashing the 2027 forecast by a steeper 235,000 bpd to 8.6 million bpd. The culprit: an escalating campaign of Ukrainian drone strikes targeting the energy infrastructure that keeps Russia’s oil machine running.

August 2026 production data paints an even grimmer picture for Moscow. Russian crude output averaged just 8.36 million bpd that month, dropping 200,000 bpd from July and a massive 695,000 bpd compared to the same period last year. Those figures suggest Russia could be heading toward production lows not seen in roughly 17 years.

Death by a thousand drones

Ukraine’s strategy of targeting Russian refineries and energy sites has shifted from an occasional nuisance to a systemic threat. Facilities in regions like Saratov and Yamalo-Nenets have absorbed repeated strikes, and the cumulative damage is proving far harder to fix than individual hits might suggest.

Western sanctions have made that repair problem significantly worse. Sourcing replacement parts and specialized equipment for damaged refineries is difficult when most of the world’s industrial suppliers won’t do business with you.
