**Summary**: Ukrainian drones reportedly targeted the small 'Pervy Zavod' refinery in Russia’s Kaluga region, adding to a pattern of strikes on Russian fuel infrastructure amid reports of a nationwide fuel crunch. While the plant is small, the cumulative effect of repeated disruptions is tightening Russia’s domestic product balance and supporting refined product cracks and crude risk premium.

## Detail

1) What happened: Reports indicate Ukrainian drones struck the 'Pervy Zavod' mini oil refinery in Russia’s Kaluga region (~300 km from Ukraine). This follows a sustained campaign of Ukrainian drone attacks on Russian refineries and oil export infrastructure, with separate reporting today already pointing to a fuel crisis affecting almost every Russian region.

2) Supply impact: On a standalone basis, Pervy Zavod is a small, regional refinery; even if output is fully halted, the direct volumetric impact on global crude and products markets is negligible. However, the key development is the continued expansion of the target set—mini refineries and regional plants are now being hit in addition to large complexes like Yaroslavl and export hubs like Ust‑Luga. Russia has already been forced to reconfigure runs and export flows, and reports of a broad domestic fuel crisis suggest internal distribution and refining capacity are under growing stress. The incremental outage will marginally tighten Russia’s product availability and can force higher imports or reduced exports at the margin.

3) Affected assets and bias: The primary impact is on refined product cracks (especially diesel and gasoline) and the geopolitical risk premium in crude benchmarks. Brent and WTI are biased modestly higher as markets price in increased probability that Russia’s refining/output issues evolve into export constraints—particularly on diesel and naphtha—over the coming weeks. European diesel futures, gasoline cracks, and Russian Urals/ESPO differentials versus Brent are sensitive. Freight for clean product carriers out of the Baltic and Black Sea could also remain firm if exports are reshuffled.

4) Precedent: Earlier in 2024–25, Ukrainian drone attacks on Russian refineries (e.g., Ryazan, Nizhny Novgorod) generated noticeable moves in diesel cracks and temporarily widened Urals discounts before Russia adjusted runs and export mix. The pattern suggests markets respond more to the cumulative campaign than to any single strike.

5) Duration: The direct outage at a small plant is likely transient, but the cumulative effect of repeated hits across Russia’s refining system is becoming structural for the medium term. As long as Ukraine demonstrates the capability and intent to keep expanding the target set, markets will maintain an elevated risk premium on refined products and, to a lesser extent, crude.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Gasoil futures (ICE), U.S. RBOB gasoline, Urals crude differentials, Clean product tanker freight (Baltic/Black Sea)
