Impact verdict
Low impact. LOW: No concrete London Market loss pathway has been evidenced. Source reporting confirms a power outage at Mariupol port but does not document named insured asset damage, port/waterway closure, vessel or cargo loss, sanctions-related asset action, claims activity, or market pricing impact. Materiality remains low until physical damage scope, operational status of berthed vessels, and duration of disruption are corroborated.
