**Summary**: Ukraine conducted its largest drone attack on Moscow in two years, repeatedly striking the Moscow/Kapotnya oil refinery, one of Russia’s 10 largest plants (~11 mtpa). The attack sparked fires, damaged fuel infrastructure, and forced temporary flight disruptions at Moscow airports, reinforcing the vulnerability of Russian refining capacity and adding upside risk to refined product cracks and crude benchmarks.

## Detail

Reports from Ukrainian and Russian sources confirm that Ukrainian unmanned systems conducted a large-scale drone strike wave against Moscow and other regions overnight, with Russian officials citing 194 drones aimed at the capital and 555 across Russia. A key target was the Moscow (Kapotnya) oil refinery, located ~15 km from the Kremlin and counted among Russia’s 10 largest refineries with an annual capacity around 11 million tonnes (≈220 kb/d). Ukrainian sources state this is the second successful hit on the refinery in a week, with confirmed fires and at least one fuel storage tank suffering catastrophic damage.

This is not an isolated incident: there is already an existing alert series on repeated attacks against this facility. The new element is the scale of the drone wave and evidence of recurring damage, suggesting the plant is becoming a sustained wartime choke point rather than a one-off disruption. While precise current throughput loss is unclear, even a partial curtailment of 100–200 kb/d of refining capacity, if prolonged, tightens Russian domestic product balances (particularly gasoline and diesel) and may lower net exports into global markets, especially to Turkey, MENA, and LatAm.

Immediate market impacts skew bullish for refined products (diesel/gasoil, gasoline) and moderately supportive for crude benchmarks (Brent, Urals differentials), primarily via higher regional refining margins and risk premium. If Russian authorities keep the refinery offline for safety/repairs or operate it below capacity due to repeated strike risk, the effect could persist for weeks. Historically, prior Ukrainian drone campaigns against Russian refineries in 2024 produced multi-percent moves in European diesel cracks and noticeable, if smaller, lifts in Brent.

Beyond direct supply loss, the demonstration that Ukraine can launch several hundred drones deep into Russian airspace raises a structural geopolitical risk premium for Russian energy infrastructure more broadly—including other refineries, export terminals, and storage hubs in western Russia. The likely market reaction is: firmer European product cracks, support for Brent/ICE gasoil, mild widening of Urals discounts, and increased hedging demand in energy futures over the near term. Duration is medium: days for headline-driven spikes, with a potentially longer-lasting premium if further strikes follow.
