**Summary**: A drone strike has shut the CDU‑6 crude unit at Russia’s 340 kb/d Ryazan refinery, with reports of damaged pipelines and halted operations on one of its main processing lines. This compounds Russia’s recent refinery outage pattern and tightens regional product balances, particularly for gasoline and diesel in western Russia and nearby export markets.

## Detail

Reuters-confirmed reports indicate a drone attack has forced the shutdown of the CDU‑6 crude distillation unit and damaged associated pipelines at Russia’s Ryazan refinery, one of the country’s largest with nameplate capacity around 340,000 b/d. While the entire plant is not confirmed offline, CDU‑6 is described as one of the main crude processing units, implying a sizable fraction of throughput is currently constrained.

On the supply side, immediate impacts are on refined products rather than crude extraction. Assuming CDU‑6 represents roughly one-third to one-half of the refinery’s capacity, this suggests 110,000–170,000 b/d of crude runs curtailed in the near term. The Ryazan facility is a key supplier of gasoline and diesel to the Moscow region and also contributes to export streams via Baltic and Black Sea ports. In an environment where Russian refined product exports are already volatile due to prior drone attacks and infrastructure bottlenecks, another significant outage supports higher cracks and regional product prices.

Market-wise, the direct impact on global crude balances is modest but non-trivial when layered on top of existing Russian refinery disruptions. Expect support for:
- European diesel and gasoline futures (bullish, particularly front spreads)
- Urals and ESPO crude differentials could weaken marginally versus benchmarks if domestic demand for Russian crude falls due to reduced refining runs.
- Brent and WTI are likely to see a risk-premium bid, but the price impulse should be limited (order of ~1–2%) unless subsequent reports confirm a prolonged, full-plant outage or follow-on strikes at additional facilities.

Historical precedent from earlier 2024–26 Ukrainian drone campaigns on Russian refineries shows that each large-unit outage can move regional products by several percentage points intraday, with effects persisting days to weeks depending on repair timelines. Russian operators have often restored partial operations within 1–4 weeks, but cumulative damage has eroded spare processing capacity.

Duration of impact will hinge on repair time for CDU‑6 and pipelines. A short outage (days) implies a transient spike in Russian domestic fuel prices and mild support for European cracks. A multi-week disruption would tighten product exports into Europe, Turkey, and North Africa more structurally, embedding a small but durable risk premium into refined products and, to a lesser extent, into Brent.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Gasoil futures (ICE), European gasoline futures, Urals crude differentials, Russian refined product exports
