**Summary**: Ukraine claims to have attacked at least 24 of 33 major refineries in European Russia, leaving only large plants east of the Urals (Omsk, Angarsk) outside the reported strike zone. If damage is significant and sustained, this could materially tighten Russian refined product exports, lifting crude and product prices and widening European diesel/gasoil cracks.

## Detail

1) What happened:
A Ukrainian source reports that Ukraine has attacked all large refineries in the European part of Russia, specifying at least 24 out of 33 Russian refineries with capacities above 1 million tonnes per year, and a total of 158 strikes. It notes that among the largest facilities, only the Omsk and Angarsk refineries east of the Urals remain outside the affected zone. While this is a partisan source and damage levels are unconfirmed, the scale of claimed targeting is materially larger than previous single-facility drone strikes.

2) Supply/demand impact:
Russia is a key exporter of diesel, gasoline, and naphtha, especially to non-Western markets after EU embargoes. European Russia hosts the majority of its refining capacity and is critical for export logistics via Baltic and Black Sea ports. If even a subset of these 24 refineries have sustained damage sufficient to lower throughput by several hundred thousand barrels per day in aggregate, refined product exports (notably diesel and vacuum gasoil) could see a short-term drop. That would tighten middle distillate balances in Europe, the Mediterranean, and parts of Africa and Latin America reliant on Russian barrels. Crude production impact is less direct in the near term, but prolonged refining outages could force Russia to either discount more crude to Asia or curtail upstream output if storage saturates.

3) Affected commodities/assets:
Likely bullish pressure on Brent and Urals-linked grades, with a stronger move in diesel/gasoil cracks than in flat crude. European gasoil futures and crack spreads vs Brent could rise >3–5% on confirmation. Freight rates in the product tanker market (MRs, LR2s) could firm as trade flows re-route. Russian domestic fuel prices and inflation risk increase, but the global macro effect is modest unless outages are prolonged.

4) Historical precedent:
Earlier 2024–2025 Ukrainian drone strikes on individual Russian refineries (e.g., Tuapse, Ryazan) generated short-lived spikes in European diesel cracks and localized Russian supply tightness, but the system adjusted within weeks via higher runs elsewhere and alternate imports. A coordinated, multi-site campaign targeting most of European Russia’s capacity would be unprecedented in this war and more comparable—on a smaller scale—to the 2019 Abqaiq-Khurais attack in Saudi Arabia, which moved Brent >10% intraday.

5) Duration of impact:
Market impact will hinge on verification and damage assessments over the next 24–72 hours. If many strikes are intercepted or cause only cosmetic damage, the effect will be transient (days). If several large refineries (e.g., >200–300 kb/d each) are offline for weeks, the refined product tightness and risk premium in cracks could be sustained through at least the next 1–2 months, especially heading into peak summer demand.
