**Summary**: Ukraine claims successful attacks on Russia's Slavneft-YANOS and Bashneft-Novoil refineries plus vessels in the Black Sea shadow fleet, following renewed high-level US intelligence support. This materially escalates the campaign against Russian oil infrastructure and export logistics, sustaining upside risk for crude and products and widening the Russia-specific risk premium.

## Detail

1) What happened: In the latest wave of deep strikes, Zelensky states Ukrainian forces hit the Bashneft-Novoil refinery in Bashkortostan (~1,300 km from the front) and again struck the Slavneft-YANOS refinery in Yaroslavl, one of Russia’s five largest refineries (nameplate ~15 mtpa, ~300 kb/d). Visuals show multi-point fires at YANOS despite Russian claims all drones were downed. Additional reported hits include two Russian patrol boats and shadow-fleet vessels in the Black Sea. These events come alongside confirmation that US–Ukraine intelligence sharing has returned to previous highs, improving targeting efficiency.

2) Supply impact: YANOS and Bashneft-Novoil are core to Russian domestic fuels and exportable products (diesel, gasoline, VGO). While current reports don’t quantify damage duration, repeat hits on YANOS indicate sustained operational risk and potential cumulative capacity loss. Even temporary outages of 100–200 kb/d equivalent (a small fraction of their combined capacity) would tighten regional product balances and could force export reallocation or cuts. Strikes on shadow-fleet tonnage raise the cost and risk of Russian crude/product exports via the Black Sea and may reduce effective loadings or increase insurance and freight premia.

3) Affected assets/direction: The immediate impact is bullish Brent and Dubai benchmarks, ICE gasoil, and European diesel cracks, and mildly supportive for global refining margins (especially non-Russian complex refineries). Russian Urals and ESPO may face wider discounts versus Brent on heightened export/logistics risk. Tanker freight rates in Black Sea/Med routes and war risk premia should firm.

4) Precedent: Previous Ukrainian strikes on Russian refineries in 2024–26 produced multi-week outages and persistent risk repricing in refined products, especially diesel, with episodic 2–5% moves in crack spreads. Repeated targeting of the same large refineries and associated logistics suggests a campaign with structural implications for Russian export reliability, not a one-off.

5) Duration: The market impact is medium-term. Physical damage will likely be repaired over weeks to months, but the demonstrated ability to repeatedly penetrate deep into Russian territory and to hit shadow-fleet assets embeds a lasting geopolitical risk premium into Russian-linked oil flows and global product markets.
