Explosions in Crimea and Yaroslavl: Oil refinery, airbase, and substations attacked

Impact verdict

Medium impact. Loss pathways concentrate in Russia: named refinery and oil terminal hits create energy property and business-interruption exposure; the Crimea airbase strike exposes war-risk covers on military aviation assets; substation hits touch power-grid property and BI books; and Kerch port infrastructure extends risk into marine cargo and port war-risk. Direct insured exposure sits primarily with Russian domestic carriers; London Market relevance arises from international war-risk, energy, political-risk and marine covers touching named Russian assets or counterparties, and from accumulation implications as long-range Ukrainian strikes on Russian energy and transport infrastructure continue to escalate. Severity cannot be banded without damage and loss disclosure.
