How Maritime Insurance Works
Maritime insurance is a complex, multi-layered system protecting shipowners, operators, and cargo interests. The three main categories are: Protection & Indemnity (P&I) covering third-party liabilities including crew injury, pollution, and cargo damage; Hull & Machinery (H&M) covering physical damage to the vessel; and War Risk covering losses from conflict, piracy, terrorism, and political violence.
The International Group of P&I Clubs — 12 mutual insurance associations — covers approximately 90% of global ocean-going tonnage. War risk premiums are set by the Joint War Committee (JWC) of Lloyd's Market Association, which designates “Listed Areas” where additional premiums apply. During the 2026 Hormuz crisis, war risk premiums surged from 0.1% to over 2% of hull value — turning a $50,000 transit into a $1M+ insurance cost.
Key Insurance Metrics
War Risk Premiums
Additional premiums for transiting Listed Areas. Can surge 10-20x during crises. Directly affects voyage economics and routing decisions.
P&I Club Calls
Annual mutual premium calls from International Group clubs. General increases signal rising claims frequency across the industry.
Hull & Machinery Rates
Insurance rates for vessel physical damage. Affected by fleet age, loss ratios, and reinsurance market conditions.
Claims Trends
Major claims (>$1M) from groundings, collisions, fires, and total losses. Large losses drive future premium adjustments across the market.
