**Summary**: Russia’s Syzran refinery has fully stopped operations after the May 21 Ukrainian strike damaged its primary crude distillation unit, which accounts for over 70% of capacity. Repairs may take more than a month, extending the ongoing series of disruptions to Russian refining. This tightens Russian products supply, particularly diesel, and supports a higher risk premium in oil and European distillate markets.

## Detail

1) What happened:
Reuters-confirmed reporting (item [3]) states that Russia’s Syzran refinery has halted operations following the 21 May Ukrainian attack. The strike hit the AVT‑6 primary distillation unit, responsible for more than 70% of the plant’s throughput. The facility is expected to be offline for over a month. This follows a broader Ukrainian campaign against Russian refineries and, per other feeds already flagged in existing alerts, against pumping stations and other energy infrastructure.

2) Supply impact:
Syzran’s nameplate capacity is roughly 8–9 mtpa (~160–180 kb/d). With the key AVT‑6 unit damaged and the whole plant shut, effective output loss is close to full capacity for the outage duration. Over a month, that implies roughly 5–6 million barrels of lost Russian product supply, skewed to diesel and vacuum gasoil. Russia has already imposed temporary fuel export restrictions at various points to stabilize its domestic market; this hit adds incremental pressure and reduces flexibility to maintain export flows while meeting internal demand. On the crude side, barrels can be re‑routed to other refineries or exported, so the immediate constraint is on refining capacity and diesel availability, not upstream production.

3) Affected assets and direction:
The most direct impact is bullish for European and Mediterranean diesel/gasoil cracks and for Russian product export differentials (CPC, Baltic/Black Sea diesel). Brent and WTI see support via higher refined product cracks and sustained geopolitical risk premium on Russian energy infrastructure. Front‑month ICE gasoil futures and time spreads could widen >1% as traders price in a tighter near‑term balance. European utilities and industrials that rely on Russian middle distillates may need to source alternative supplies, supporting US Gulf Coast and Middle East diesel flows to Europe.

4) Historical precedent:
Earlier Ukrainian strikes on Russian refineries in 2024–25 induced repeated spikes in European gasoil cracks and Russian export differentials, even when absolute global crude balances were comfortable. Markets have treated cumulative Russian refinery outages as a meaningful factor in products pricing.

5) Duration:
The reported repair time of "more than a month" suggests a transient but non‑trivial disruption. If follow‑on attacks keep plants offline or deter repairs, the effect could become semi‑structural for the 1–3 month horizon, maintaining an elevated risk premium in refined products and modest support for benchmark crude.
