**Summary**: Ukrainian drones reportedly attacked Russia’s Yaroslavl oil refinery again overnight, with fires and explosions observed before authorities claimed the attack was repelled. This adds to a sustained campaign against large Russian refineries in the European part of the country and reinforces upside risk to Russian product exports and global diesel/gasoil cracks.

## Detail

1) What happened:
Intelligence reports indicate the Yaroslavl oil refinery in Russia was again targeted by Ukrainian drones overnight, with local accounts citing fires, explosions, temporary road closures and air-raid sirens. While the regional governor claimed the attack was repelled, the repeated targeting of this plant, alongside earlier confirmation that at least 24 of 33 major Russian refineries (>1m tpa) in European Russia have been hit a cumulative 158 times, points to heightened operational risk and intermittent outages.

2) Supply impact:
The Yaroslavl refinery is one of the significant refineries feeding Russia’s domestic fuels market and exports of gasoline and diesel into Europe, Africa and Latin America via traders. Even if physical damage from this particular strike is not yet fully verified, the pattern of repeated hits is already constraining effective Russian refining capacity, increasing unplanned maintenance and forcing throughput reductions. Previous waves of Ukrainian strikes in Q1–Q2 on Russian refineries were associated with temporary cuts in gasoline output and tighter domestic balances, prompting Moscow to consider or enact product export restrictions. A fresh successful strike on Yaroslavl increases the probability of renewed export curbs or lower net exports of gasoline and diesel in coming weeks.

3) Affected assets and direction:
The immediate market impact channel is refined products rather than crude supply. Gasoil/diesel futures (ICE gasoil, NYMEX ULSD) and European gasoline cracks to Brent are biased higher on increased risk premia for Russian product flows. Brent and WTI should also see moderate support via the refined-product-led tightness and higher geopolitical risk premium on Russian energy infrastructure. European physical markets (ARA diesel, gasoline) are particularly exposed. If Russian export volumes are visibly curtailed, freight rates on clean product tankers out of the US Gulf and Middle East into Europe could firm as replacement barrels are sourced.

4) Historical precedent:
Earlier Ukrainian drone campaigns against Russian refineries in 2024 produced noticeable moves in product cracks and supported Brent by several dollars as the market reassessed Russian export capability. The cumulative effect of repeated strikes, even when individual damage reports are ambiguous, has been to lift the perceived structural risk premium on Russian refining assets.

5) Duration:
The immediate price reaction is likely to be in the short term (days) pending clarity on physical damage and any Russian policy response on exports. However, the structural impact is medium-term: persistent attacks are raising insurance, security and operational costs while making high-availability operation of Russian refineries less credible, embedding a higher and more volatile risk premium in refined products and, by extension, in the crude complex.
