**Summary**: Ukraine’s General Staff confirms that five of Russia’s largest oil refineries were hit since October 30, including Omsk, Kirishi, Ryazan, Nizhny Novgorod and Yaroslavl. Concentrated damage to high-capacity plants raises risks for Russian diesel and gasoline exports, supporting European product cracks and potentially tightening global middle distillate balances.

## Detail

1) What happened:
Ukraine’s General Staff states that, since October 30, Ukrainian forces have struck five of Russia’s largest oil refineries: Omsk, Kirishi, Ryazan, Nizhny Novgorod, and Yaroslavl. These are among Russia’s most important processing centers, accounting collectively for a substantial share of national refining capacity and exportable products (diesel, gasoline, fuel oil, vacuum gasoil).

2) Supply/demand impact:
The report confirms targeting but does not specify the extent or duration of damage at each site. Historically, Ukrainian drone attacks have taken individual Russian refineries or units (e.g., catalytic crackers) partially offline for days to weeks, cutting throughput by tens of thousands of barrels per day per site. If even 20–30% of combined capacity at these five refineries is impaired for several weeks, the notional impact could be on the order of 0.3–0.6 mb/d of refined product output, with a disproportionate effect on diesel export availability.

Russia is a key exporter of diesel to global markets (including via transshipment to Africa, Latin America, and Asia). Sustained impairment would tighten middle distillate balances, particularly in Europe, which remains exposed despite some diversification post‑2022. Domestic Russian fuel prices and allocation priorities could further curb exports if Moscow prioritizes internal supply.

3) Affected assets and direction:
- European diesel/gasoil futures (ICE Gasoil): Bullish on potential reduction in Russian diesel exports and higher replacement costs.
- European gasoline and fuel oil cracks: Mildly bullish, depending on which units are affected.
- Urals and Russian product export differentials: Could widen discounts if flows are rerouted or if quality shifts, but total volumes likely down.
- European natural gas and power: Slight bullish tail risk if fuel-switching to fuel oil or gas is needed at the margin.

4) Historical precedent:
Earlier waves of Ukrainian strikes on individual Russian refineries have led to noticeable, though episodic, strength in diesel cracks and volatility in Russian export flows, but Russia has generally managed to restore capacity within weeks and reoptimize flows.

5) Duration of impact:
The structural impact depends on damage severity. If damage is modest and repairs are rapid, the effect is likely a several‑week support for product cracks rather than a major structural shift. However, the confirmation that five top-tier refineries were hit in a short window increases the probability of recurring outages and a higher, more persistent geopolitical risk premium embedded in refined products for the coming months.
