**Summary**: Ukrainian drones and cruise missiles have struck the Moscow/Kapotnya oil refinery, triggering a major fire at a plant with ~12 mtpa capacity that supplies around 40% of Moscow’s fuel. Scale of damage and outage duration are still unclear, but the attack adds to the pattern of Ukrainian strikes on Russian refining, tightening product balances and lifting the geopolitical risk premium in oil.

## Detail

1) What happened:
Multiple reports indicate Ukraine launched a large-scale combined UAV and FP-5 “Flamingo” cruise‑missile attack on Moscow Oblast overnight, with one of the main targets the Moscow Oil Refinery at Kapotnya. Visuals and local accounts describe a significant fire at the facility; separate reports say the plant supplies roughly 40% of Moscow’s gasoline and diesel. Russian authorities claim over 1,600 drones were intercepted overall, but acknowledge impacts on the refinery and a major warehouse complex.

2) Supply/demand impact:
The refinery’s nameplate capacity is about 12 million tonnes/year (~240 kb/d). Even a partial, short‑term outage (e.g., 25–50% for several weeks) would temporarily remove 60–120 kb/d of refined products from the Russian system. Direct global crude supply is unaffected, but Russian product export flexibility may be constrained if domestic supply to the capital must be prioritized, potentially trimming seaborne diesel/gasoil and naphtha exports. If damage is severe and offline time extends into months, cumulative lost product exports could reach several million barrels, tightening European and global middle-distillate balances.

3) Affected assets and direction:
Oil markets should price in additional geopolitical and infrastructure risk premia on Russian refining. Front-month Brent and WTI are biased higher (>1% possible intraday) on concerns of continued Ukrainian strikes on Russian energy infrastructure and potential ripple effects on product cracks. European diesel/gasoil futures, gasoline cracks, and Russian Urals differentials versus Brent are particularly sensitive. Freight rates in the Baltic and Black Sea product trades could also firm if Russian export flows need rerouting.

4) Historical precedent:
Previous Ukrainian drone strikes on Russian refineries in 2024–2026 triggered short-lived but notable moves in product cracks and supported Brent by 1–3%, especially when markets were already tight. Repeated hits created a cumulative effect on Russia’s refining throughput and export capacity.

5) Duration of impact:
Headline and risk-premium effects are immediate but may fade in days if the fire is contained and damage localized. Structural impact emerges only if assessments show extended downtime or a sustained campaign degrading Russian refining capacity. Given the escalating scale of this attack (described as the largest drone raid on Moscow to date), markets will likely assume elevated ongoing risk to Russian energy infrastructure over the coming weeks.
