Russia's Orsk refinery suspended processing on August 11th following a drone attack, according to sources

Strikes on Russian refining capacity have followed a familiar pattern in this conflict: attacks cluster in waves, outages are typically partial and temporary, and the market effect runs less through crude than through products, since damaged distillation capacity frees up crude for export while tightening domestic and export supply of diesel and gasoline. The distinction that matters is between a brief suspension for damage assessment and a sustained loss of units; past episodes have tended to resolve toward the former, with restart timescales of days to weeks when hits land on peripheral equipment rather than primary distillation. Orsk is a smaller, inland plant in the Orenburg region, and attacks reaching that depth have previously been read as an expansion of target range rather than a shift in aggregate capacity loss. The established transmission channel is product cracks and the Russian export mix: crude loadings rising as runs fall, diesel and gasoline differentials firming, with the government response, typically temporary export restrictions on products, the recurring policy follow-on. What is worth watching is confirmation of which units were hit, the restart timeline, and whether further strikes land in the same wave, since it is the cumulative share of capacity offline rather than any single plant that has historically moved spreads.
