**Summary**: Ukraine reportedly hit Russia’s Kotovo oil refinery with a massive drone attack, causing a large fire. This adds to the pattern of strikes on Russian refining capacity, tightening product supply and supporting refined product cracks and Brent time spreads.

## Detail

1) What happened:
A large-scale Ukrainian drone attack on Russia intercepted 334 drones, with local reporting indicating that the Kotovo oil refinery was hit and a large fire ensued. While precise damage and outage duration are not yet quantified, the description is consistent with at least a partial, near‑term loss of refining capacity. This follows a broader Ukrainian campaign against Russian refineries in 2024–26 that has periodically taken several hundred thousand b/d of capacity offline.

2) Supply/demand impact:
Absent exact nameplate capacity in the report, Kotovo should be treated in line with prior medium‑sized Russian refineries (typically 150–300 kb/d). Even a temporary loss of 100–200 kb/d of runs for several weeks can tighten regional diesel, gasoline, and fuel oil balances, particularly given Russia’s role as a key exporter of diesel and vacuum gasoil into global markets via third countries. Markets are already on edge with Brent trading above $106, reflecting a material geopolitical risk premium; any confirmed incremental disruption to Russian product exports can justify a >1% move in crack spreads and potentially in flat price if damage is significant or repeated.

3) Affected assets and direction:
– Brent and WTI: Bullish bias via higher risk premium and concern over more systematic degradation of Russian refining.
– European diesel cracks (ICE gasoil) and Singapore middle distillates: Bullish on tighter export availability from Russia.
– Urals and ESPO differentials: Mixed; crude may trade slightly weaker relative to benchmarks if domestic refining runs are curtailed and more crude is pushed to export, but this depends on Russia’s ability to redirect flows.

4) Precedent:
Earlier Ukrainian drone strikes on Lukoil’s Nizhny Novgorod and other refineries in 2024–25 triggered immediate jumps in European diesel cracks (3–7% intraday) and modest firming in Brent time spreads, even when outages were partially mitigated over weeks.

5) Duration:
If Kotovo’s damage is limited, outage may be several days to a few weeks, making the primary impact transitory but recurring if the campaign continues. Should damage prove severe or if follow‑on strikes occur, the cumulative effect becomes structurally bullish for refined products through the season, reinforcing the current risk premium embedded in oil.
