**Summary**: Ukrainian drones reportedly hit the Slavneft-YANOS refinery in Yaroslavl, one of Russia’s largest, processing around 15 mtpa of crude. Repeated attacks on this asset reinforce upside pressure on refined product prices and Russian export logistics risk.

## Detail

1) What happened:
New reports indicate Ukrainian attack drones struck the Slavneft-YANOS refinery in Yaroslavl this morning, igniting multiple fires. The facility is one of Russia’s largest refineries, with nameplate capacity of roughly 15 million tons of crude per year (~300 kbpd). This site has already been a target in prior strikes, suggesting a sustained Ukrainian campaign against core Russian refining infrastructure.

2) Supply/demand impact:
Actual throughput loss depends on the damage extent and whether key process units (CDUs, FCC, hydrotreaters) are affected. Even a partial shutdown of 100–200 kbpd for several weeks would materially tighten regional supplies of gasoline and diesel, especially for Western Russia and export flows via Baltic ports. Russia remains a major exporter of diesel and other middle distillates; constraints at YANOS can reduce export availability, increase domestic balancing challenges, and necessitate rerouting crude to other refineries or export ports.

3) Affected assets and direction:
Global crude benchmarks (Brent, Urals differentials) will react modestly, but refined products are more directly exposed. European diesel/gasoil futures and cracks vs. Brent are biased higher, as are gasoline cracks, particularly in Northwest Europe. Russian product export differentials and freight on Baltic and Black Sea product routes may widen on dislocation. European power and gas markets are indirectly supported by higher oil product prices via cross-fuel substitution. RUB assets and Russian corporates in the refining sector also face incremental risk premium as infrastructure vulnerability is underscored.

4) Historical precedent:
Earlier 2024–2026 waves of Ukrainian drone attacks on Russian refineries repeatedly pushed European diesel cracks sharply higher, sometimes 10–20% in short windows, especially when multiple large sites were offline simultaneously. Markets have become somewhat inured, but attacks on top-tier sites still move product curves.

5) Duration of impact:
If damage is superficial and repaired within days, the impact may be transient but still supportive for prompt cracks and spreads. Structural risk is rising, however: recurring strikes on the same major refinery increase perceived vulnerability of Russian refining capacity, warranting a persistent risk premium in European diesel and gasoline relative to crude over the coming months.
