**Summary**: Ukrainian drone attacks have forced Rosneft to halt operations at its Tuapse and Novokuybyshevsk refineries and damaged associated port infrastructure. The outages temporarily remove a notable volume of Russian refining capacity and could constrain exports of diesel and other products, tightening European and global products markets.

## Detail

1) What happened:
Russian sources report that Rosneft has stopped operations at two refineries—Tuapse (on the Black Sea) and Novokuybyshevsk—after Ukrainian drone strikes damaged key processing units and port infrastructure. Earlier alerts already flagged these facilities as hit; this latest report confirms operational shutdowns, not just minor damage.

2) Supply/demand impact:
Tuapse is a major export-oriented refinery on the Black Sea, while Novokuybyshevsk (Samara region) is a significant domestic and export supplier of gasoline and middle distillates. Combined nameplate capacity is on the order of several hundred thousand barrels per day; even if only part of that is offline, the immediate effective loss of refined product output could be 200–400 kb/d in the short term. Russia has been a key exporter of diesel and other middle distillates, especially into Africa, Latin America, and via re‑exports into Europe post‑sanctions. Any sustained outage tightens the global diesel balance, potentially lifting European gasoil and global diesel cracks.

3) Affected assets and direction:
Refined product benchmarks (ICE gasoil, NY Harbor ULSD) are biased higher, with a plausible >1% move as traders price tighter near‑term availability from Russia. Brent/WTI may also see marginal support from loss of refining capacity and possible re‑routing of crude flows, but the primary impact is on products and cracks rather than headline crude balances. Freight rates for Black Sea and Baltic product tankers may firm if flows are disrupted or rerouted. Russian domestic fuel prices and inflation expectations could be pressured, adding to RUB downside risk.

4) Historical precedent:
Prior Ukrainian strikes on Russian refineries in 2024–2025 triggered noticeable spikes in European diesel and crack spreads, even when capacity loss was temporary. Similar attacks typically led to multi‑week periods of elevated product premiums until repairs and rerouting normalized flows.

5) Duration:
Drone‑strike damage to processing units can take weeks or longer to fully repair, especially under sanctions and parts constraints. If both refineries remain partially or fully offline for an extended period, the tightness in diesel and other products could persist for several weeks, sustaining higher cracks and regional price premiums. Further Ukrainian targeting of Russian refining infrastructure would add incremental upside risk.
