**Summary**: Ukrainian forces struck the Slavneft‑YANOS refinery in Yaroslavl, one of Russia’s largest, triggering a major fire and reported fuel shortages in the region. The plant’s 15 mtpa capacity and role in supplying central and northwestern Russia, including Moscow, imply a meaningful hit to regional product output and potential uptick in global refined product and crude risk premia.

## Detail

1) What happened:
Ukraine’s military intelligence (HUR) and associated units report a successful overnight long‑range drone strike on the Slavneft‑YANOS refinery in Yaroslavl, Russia. Multiple reports state the refinery is still burning, with local commentary describing “fuel chaos” and panic buying at regional fuel stations. YANOS has nameplate capacity of up to 15 million tonnes per year (roughly 300 kb/d) and is a key supplier of gasoline, diesel, and jet fuel to central and northwestern Russia, including the Moscow area.

2) Supply impact:
The immediate question for markets is duration and extent of outage. Even a partial shutdown of CDU and secondary units for damage assessment and safety could take days to weeks. Assuming a conservative 30–50% effective outage for a month, the impact could be on the order of 100–150 kb/d of refined products temporarily removed from the Russian domestic system. Russia is a major exporter of diesel and other middle distillates; to stabilize domestic supply and avoid shortages in Moscow and surrounding regions, authorities are likely to divert product from export streams and/or impose temporary export constraints, tightening seaborne product availability, especially into Europe, West Africa and Latin America.

3) Affected assets and direction:
This event reinforces the ongoing pattern of Ukrainian deep strikes on Russian refining capacity, which has already eroded Russia’s export flexibility. The immediate directional bias is bullish for refined product cracks (gasoil/diesel, gasoline) and modestly supportive for Brent and Urals/ESPO differentials via higher risk premium on Russian downstream infrastructure. European diesel futures, Rotterdam cracks, and Mediterranean product benchmarks are particularly exposed. Russian domestic fuel price controls may cap local inflation but increase the likelihood of administrative export curbs, further tightening global supply.

4) Historical precedent:
Earlier waves of Ukrainian drone strikes on Russian refineries in 2024–25 produced visible but short‑lived spikes in European diesel and gasoline cracks, especially when multiple plants were hit in close succession. If Yaroslavl’s outage compounds with existing Russian refinery disruptions, the cumulative effect could be more than marginal for product markets.

5) Duration:
Base case is a transient but market‑relevant shock lasting weeks to a few months, depending on repair timelines and the Kremlin’s export policy response. The structural element is an increased and persistent geopolitical risk premium on Russian refining and product export reliability, which can underpin elevated volatility in European product markets.
