Ukraine conducts large-scale drone attack on Moscow oil refinery and other sites

Impact verdict

Low impact. Confirmed physical damage to both crude processing units at the Gazprom Neft Moscow Oil Refinery, the capital's only refinery, creates a plausible material property damage and extended business-interruption exposure for Energy Property and War Risk books. Mainstream reporting corroborates an outage with no production until at least 2027 and the facility's role supplying over a third of Moscow's fuel. Limit: No insured loss figure is yet available; quantum depends on damage assessment, BI indemnity periods, and confirmation of coverage triggers (war risk vs. conventional property) and any sanctions-related voidance. Energy, Property, and War Risk underwriters should monitor for verified loss estimates and treaty or sanctions-coverage guidance.
