Russian crude oil production dropped to 8.7 million barrels per day (bpd) in May. This output represents a 5% year-on-year decline. Production fell 10% below the country's monthly target.
Intensified Ukrainian drone attacks on energy infrastructure caused the disruption. These strikes damaged numerous refineries throughout 2026.
The IEA lowered its annual Russian crude output forecast by 200,000 bpd to 8.95 million bpd. Total crude and product exports remained stable at 7.4 million bpd in May. Russia maintained export levels by prioritizing crude shipments over domestic refining as throughput plummeted.
