**Summary**: Russia’s Yaroslavl refinery has halted crude processing after a Ukrainian drone strike damaged its AVT-3 unit, which accounts for about 40% of the plant’s capacity; another key unit was already offline from an August attack. This adds to ongoing disruptions at Russian refining assets and could tighten regional product balances, particularly for diesel, supporting a higher risk premium in oil and refined product markets.

## Detail

1) What happened:
Reuters-sourced industry contacts report that Russia’s Yaroslavl refinery has halted crude processing following a Ukrainian drone strike that damaged its AVT-3 crude distillation unit. AVT-3 represents around 40% of total plant capacity, and the refinery already had another critical unit under repair from an earlier August strike. The combined impact appears sufficient to force a full suspension of crude runs, at least temporarily.

2) Supply impact:
Yaroslavl is one of the larger refineries supplying central Russia and feeding export flows of refined products, especially diesel and vacuum gasoil, into global markets via Baltic ports. While exact capacity isn’t given in this report, Yaroslavl is typically cited around 280–300 kb/d; a full halt would remove that volume of crude runs. Assuming 200–250 kb/d of product output, this is a meaningful incremental loss on top of prior Ukrainian attacks on Russian refining. Even if some secondary units remain operable, crude run suspension points to near-total loss of output in the short term. Depending on repair timelines (weeks to months for serious CDU damage), the cumulative loss could reach several million barrels of refined products.

3) Affected assets and direction:
The immediate effect is supportive for Brent and WTI via an added geopolitical/risk premium and via expectations of tighter diesel and middle distillate balances, especially into Europe, which still indirectly depends on Russian-origin molecules (via rerouted trade). ICE gasoil and ULSD futures should see a stronger bid than crude benchmarks, steepening cracks. Russian Urals and ESPO pricing could see localized pressure if crude is backed up domestically by reduced refining demand, but seaborne product markets ex-Russia should tighten. Freight rates for clean tankers in the Baltic/ARA complex may firm as trade flows reconfigure.

4) Historical precedent:
Earlier 2024–2025 Ukrainian drone strikes on Russian refineries (e.g., in Ryazan, Tuapse, Volgograd) triggered noticeable short-term rallies in diesel cracks and added a transient premium to Brent. Clusters of attacks had a compounding impact as markets reassessed the vulnerability of Russian downstream capacity.

5) Duration:
The price impact is likely to be more than a one-day headline move because another unit was already offline, suggesting protracted reduced capacity. However, it remains a medium-term (weeks–few months) disruption rather than a structural loss. The key risk is escalation into a broader and more systematic campaign against Russian refining, which would justify a more persistent risk premium in products and, secondarily, crude.
