**Summary**: Social media reports from Omsk suggest ongoing explosions and claimed hits on Russia’s largest refinery. If damage is confirmed and sustained, this would further tighten Russian refined product exports and support global diesel and fuel oil cracks.

## Detail

1) What happened: Multiple local reports from Omsk indicate prolonged buzzing sounds, explosions, and preliminary claims of strikes on Russia’s largest oil refinery. The Omsk refinery (operated by Rosneft) is a key hub in Western Siberia and commonly cited as Russia’s largest by throughput. Earlier today there were separate confirmed or semi‑confirmed drone attacks on Russia’s Ust‑Luga export hub. Together these suggest a coordinated Ukrainian campaign against Russian energy infrastructure.

2) Supply/demand impact: Omsk has a nameplate capacity on the order of 400–450 kb/d. Even a partial impairment can temporarily knock out 100–300 kb/d of refined output (gasoline, diesel, fuel oil) depending on which units are hit and how quickly they can be restored. Onshore inventories and rerouting from other Russian refineries could cushion domestic supply, but exportable surplus, particularly diesel/gasoil and fuel oil, would be at risk. Given Russia’s importance in global middle distillate and fuel oil export flows, another large refinery under attack after Ust‑Luga materially increases tail risks of supply shortfalls into Europe, the Mediterranean, and some Latin American and African buyers.

3) Affected assets and direction: The immediate market-sensitive angle is refined products rather than crude. Expect upward pressure on European and Asian diesel/gasoil cracks versus crude, High Sulphur Fuel Oil (HSFO) and potentially vacuum gasoil. European front-month ICE gasoil futures could move >1–2% as traders price in risk of reduced Russian flows. Urals and ESPO crude differentials may also react if refinery run cuts increase crude availability domestically while export logistics remain constrained. Freight for Baltic and Black Sea clean and dirty product tankers could see volatility depending on how exports are reconfigured.

4) Historical precedent: Past Ukrainian attacks on Russian refineries in 2024–2025 triggered short‑term spikes in product cracks and regional price dislocations, although Russia often repaired units within weeks. However, cumulative damage across multiple sites has tended to keep a persistent albeit modest risk premium in European diesel.

5) Duration: Impact duration hinges on damage severity. A short‑lived fire in peripheral units might have a 1–2 week effect. Significant damage to key distillation or upgrading units could limit output for months, reinforcing a structural bid under global middle distillates. For now, this is an early‑stage, high‑uncertainty but clearly market‑relevant risk that adds to today’s Ust‑Luga disruption.
