**Summary**: Reuters-linked reports say Russia’s Ryazan refinery has suspended processing after September 6 drone strikes, with two main CDU units (AVT‑6, AVT‑4) offline and repairs expected to take weeks. This removes roughly 12mn t/yr of crude throughput, tightening Russian diesel/gasoil and fuel oil exports at a time of escalating Middle East war risk. Expect a bullish impulse for refined products and Brent/Dubai spreads, and higher risk premiums for further strikes on Russian energy infrastructure.

## Detail

What happened: Ukrainian-language reporting citing Reuters states that the Ryazan refinery in Russia has suspended processing following the 6 September strikes. The AVT‑6 and AVT‑4 crude distillation units, with a combined capacity of about 12 million tonnes per year (~240 kb/d), are reportedly shut, while another unit (AVT‑3) has been in maintenance since mid‑May. Repairs on the damaged units are expected to take several weeks.

Supply impact: A 240 kb/d outage, even if partially mitigated by inventories and rerouting crude to other plants, is meaningful in the context of already tight global product balances and sanctions‑distorted Russian flows. Ryazan is oriented toward domestic supply and export of diesel/gasoil, fuel oil, and other light products. A multi‑week outage could temporarily remove on the order of 3–5 million barrels of refined product from export channels, depending on how much is backfilled elsewhere in the Russian system. Given that Russian refined product exports, especially diesel to Europe, have already been constrained by sanctions and previous strikes, marginal supply tightness is likely to be felt most in European diesel cracks and high‑sulfur fuel oil markets.

Market implications: This is bullish for:
- European diesel and gasoil futures (higher cracks vs Brent).
- HSFO and other Russian‑linked residual fuel markets.
- Brent and Urals/Dubai benchmarks via higher geopolitical risk premium on Russian energy infrastructure and marginally tighter products.

Historically, prior Ukrainian strikes on Russian refineries (e.g., Tuapse, Novatek Ust‑Luga condensate facility, and previous hits on Ryazan and other Volga plants) produced outsized moves in diesel cracks and contributed to a structural risk premium on European products, even when headline crude impact was limited. Markets have become somewhat desensitized to single‑site disruptions, but a confirmed multi‑week outage at a large refinery during an oil price spike (> $100) can still shift cracks and front spreads by several percent.

Duration and risk premium: The direct outage looks transient ("weeks"), but it reinforces a structural story: Ukrainian long‑range strike capabilities are steadily degrading Russian refining capacity and raising the probability of additional intermittent outages. That keeps a persistent risk premium in European and Mediterranean refined products. Immediate impact is likely a near‑term pop in diesel cracks and support to Brent time spreads, with the broader structural effect being an elevated vulnerability of Russian downstream capacity through winter.
