War Exclusions Create New Coverage Risks for Global Businesses

Latest Market Alert | 7 June 2026

Executive Summary

War exclusions are becoming one of the most important hidden coverage issues for multinational businesses, lenders and project sponsors. Recent conflict-related disruption has highlighted how standard property, cyber, marine, aviation and energy policies may respond very differently where losses are linked to war, terrorism, state-backed cyber activity or geopolitical escalation.

Why It Matters

Many businesses assume insurance will respond to disruption, asset damage or business interruption. In reality, war-related wording, cancellation rights, cyber-war exclusions and specialist buy-back clauses can materially alter coverage.

UK Commercial Impact

UK firms with overseas assets, shipping exposure, aviation dependency, infrastructure projects or international supply chains should review whether existing programmes contain war, cyber-war, terrorism or sanctions-related limitations.

Global Commercial Impact

Global insurers are increasingly focused on aggregation, attribution and exposure control. This may lead to tighter wording, higher pricing for specialist buy-backs and more detailed underwriting questions.

Our View

The risk is not simply that conflict occurs. The greater commercial risk may be discovering after an event that cover is narrower than expected. Clients should review policy wordings, exclusions and specialist extensions before relying on insurance as part of their resilience planning.
