**Summary**: Ukrainian drones have forced Rosneft to halt operations at its Tuapse and Novokuybyshevsk refineries after damaging key units and associated port infrastructure. This removes a material volume of Russian refined product supply from the market and raises risk premia on further strikes against Russian energy infrastructure.

## Detail

1) What happened:
Reuters-linked and other battlefield reporting indicates that Ukrainian drone attacks have forced Rosneft to stop operations at two refineries: Tuapse (on the Black Sea) and Novokuybyshevsk (Samara region), with additional damage to related port infrastructure. The wording “stopped operations” and “damaged key units and port infrastructure” implies more than a brief power trip – at minimum, several days of outage while damage is assessed and repairs initiated.

2) Supply/demand impact:
Tuapse is a major export-oriented refinery processing roughly 240–250 kb/d, primarily geared toward fuel oil and vacuum gasoil exports via the Black Sea. Novokuybyshevsk’s nameplate capacity is ~100–110 kb/d, focused on domestic fuels but with some export linkage via the Volga system. If both plants are fully offline, up to ~350–360 kb/d of crude intake and ~250–300 kb/d of refined product output are temporarily removed. In practice, Russia can reroute some crude to other refineries and divert export streams, but short-term export flows of fuel oil/VGO/diesel from the Black Sea and Volga-Don corridor are likely to dip. The port damage at Tuapse is particularly relevant as it can constrain seaborne flows even if refinery units restart.

3) Affected assets and direction:
The immediate impact is bullish for refined products (diesel, fuel oil, VGO) in Europe and the Med, and modestly supportive for Brent/Urals spreads. European middle distillate cracks could widen >3–5% on the headline, with Med fuel oil and VGO differentials tightening versus benchmarks. The ruble impact is marginal but the broader Russia risk premium widens. Freight rates for Black Sea product tankers may firm if port capacity is constrained and vessels are delayed or rerouted.

4) Historical precedent:
Previous Ukrainian strikes on Russian refineries in 2024–25 triggered 1–3% intraday moves in European diesel and fuel oil cracks and added a transient 0.5–1.5% to Brent as traders priced in cumulative attrition of Russian refining capacity. Markets have become somewhat accustomed to such attacks, but hitting multiple refineries plus port assets together is at the upper end of past episodes.

5) Duration of impact:
Physical disruption is likely measured in days to a few weeks for partial restart of units, longer for fully restoring damaged port infrastructure. The price impact on crude is likely transient (days), whereas refined product cracks could retain a risk premium for several weeks, especially if follow-on attacks occur or if evidence emerges of sustained capacity loss at Tuapse.
