**Summary**: Ukrainian drone strikes have forced Rosneft to halt operations at its Tuapse and Novokuybyshevsk refineries, with damage also reported to associated port infrastructure. This removes a meaningful volume of Russian refined products and potentially some crude export capacity from the market, tightening near-term diesel and fuel oil balances and lifting the geopolitical risk premium on oil.

## Detail

1) What happened:
According to report [6], Ukrainian drone attacks have stopped operations at two Rosneft refineries: Tuapse (on the Black Sea) and Novokuybyshevsk (Samara region). The strikes reportedly damaged key processing units and port infrastructure. Tuapse is a major export-oriented refinery with direct access to the Black Sea, while Novokuybyshevsk is a large inland plant feeding domestic and export flows.

2) Supply impact:
Tuapse’s nameplate capacity is roughly 12 mn tpy (~240 kb/d), and Novokuybyshevsk around 8–9 mn tpy (~160–180 kb/d). If both are fully offline, up to ~400 kb/d of refining capacity is temporarily lost. Not all capacity loss translates into export disruption, but Tuapse is a key outlet for vacuum gasoil, fuel oil, and other products into the Black Sea. Damage to port infrastructure implies immediate constraints on refined product and possibly some crude loadings. Even a partial multi-week outage can tighten European and Mediterranean diesel/fuel-oil balances and force Russian flows to re-route, raising freight and quality differentials.

3) Affected assets and direction:
Brent and WTI are likely to add at least a modest risk premium (bullish) on the combination of physical disruption and demonstration that Ukrainian strikes can repeatedly hit Russian energy assets, including export-adjacent infrastructure. Gasoil (ICE) and fuel oil cracks should widen, particularly in Europe and the Med, while Russian Urals/FO discounts may need to deepen to clear barrels via alternative routes. European natural gas is less directly affected, but any broadening of Ukrainian targeting to energy could marginally support TTF on risk perception.

4) Historical precedent:
Past Ukrainian drone attacks on Russian refineries (2023–2025) have produced 2–4% intraday moves in oil benchmarks when outages exceeded ~300 kb/d or directly affected export facilities. Strikes on Novatek’s Ust-Luga condensate complex in early 2024, for example, temporarily widened fuel oil and naphtha spreads and added a short-lived risk premium to Brent.

5) Duration:
Refinery repairs can range from days for superficial damage to months for key units or port assets. Base case is a multi-week partial outage with phased restart, but the strategic signal that export-linked Russian infrastructure is increasingly vulnerable is structurally bullish for the oil risk premium, especially amid concurrent US–Iran tensions.
