The International Group of P&I Clubs is an unincorporated association of twelve mutual marine Protection and Indemnity Clubs that share the largest marine liability losses through a Pooling Agreement and a collectively purchased reinsurance contract, providing the world’s tanker, dry cargo and container fleets with cover that no single insurer could write alone.
Category: Marine insurance Also known as: International Group, IG P&I, IGP&I First codified: Pooling Agreement first concluded 1899; modern Group constituted 1981 Related legislation: Marine Insurance Act 1906 [1]; European Commission Decision 1999/329/EC on the International Group [2]
The International Group of P&I Clubs (the ‘Group’ or ‘IG’) is the trade association and pooling-and-reinsurance vehicle through which the twelve largest mutual marine P&I clubs collaborate. The Group is unincorporated; it operates through committees, a secretariat based in London and a series of formal agreements between the participating clubs [3].
The two foundational instruments are the Pooling Agreement, which provides for the sharing of losses above an individual club’s retention and below the Group’s reinsurance attachment point, and the Group’s General Excess Loss Reinsurance Contract, which provides cover for the largest claims layered above the pool. Together these structures enable a single shipping member to enjoy cover up to approximately US$3.1bn per incident, with separate sub-limits for oil pollution (US$1bn) and passenger and seafarer claims (US$3bn in aggregate) [3].
The Group’s twelve current members are the American Club, Britannia, Gard, the Japan Club, the London Club, NorthStandard (formed in February 2023 from the merger of North of England and the Standard Club), the Shipowners’ Club, Skuld, Steamship Mutual, the Swedish Club, the UK Club and the West of England Club. Collectively the Group’s clubs insure approximately 90% of the world’s ocean-going tonnage [3][4].
Each Group club is itself an authorised insurance undertaking in its home jurisdiction. UK-domiciled clubs are authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority. The Group itself is not an insurer; it is an unincorporated association of insurers, and the contractual cover flows to the entered member through its individual club’s rules, with the pool and reinsurance operating between the clubs [5].
The Group’s structure has been examined and cleared by the European Commission under EU competition rules. The original 1985 clearance was renewed in 1999 (Commission Decision 1999/329/EC) and again in 2012, in each case on the basis that the pooling and joint reinsurance arrangements deliver consumer benefits (capacity, stability of cover, lower transaction costs) that outweigh any restrictions on competition [2][6]. Post-Brexit, the Competition and Markets Authority and the EU Commission have continued to engage with the Group on the renewal of the relevant arrangements.
International compulsory insurance regimes — including the Civil Liability Convention 1992, the Bunkers Convention 2001 and the wreck removal provisions of the Nairobi Convention — are satisfied in practice by P&I Club Blue Cards backed by the Group’s pooling structure. The Group’s collective ability to meet these obligations is treated by flag states and port states as evidence of adequate financial security [7].
A shipowner enters its vessel with one Group club, which retains the first US$10m of any qualifying claim (the individual club retention for policy year 2024/25). Losses between US$10m and the upper pool ceiling are shared among the twelve clubs in proportions reflecting tonnage entered and claims experience, under the Pooling Agreement. Above the pool ceiling, losses are paid from the Group’s collectively purchased General Excess Loss Reinsurance Contract, which provides cover up to a Group-wide aggregate currently in the order of US$3.1bn per incident [3].
The Group’s reinsurance is placed annually in the international reinsurance market through brokers acting collectively on behalf of all twelve clubs. Major reinsurers including Hannover Re, Munich Re, Swiss Re and a panel of Lloyd’s syndicates participate. Premium and structure are negotiated centrally, with allocation of cost to individual clubs based on their pool entries [3][4].
Day-to-day claims handling is performed by the entering club, which engages its own correspondents, lawyers and surveyors. The Group provides forums (the Pooling Committee, the Reinsurance Committee, the Ships’ Standards Committee) through which the clubs coordinate on common issues — sanctions compliance, climate-related disclosures, ESG initiatives, common positions in IMO negotiations and the like [3].
The composition of the Group has changed over time through mergers and a small number of withdrawals. The 2023 merger of North of England and the Standard Club into NorthStandard reduced membership from thirteen to twelve. The Group does not admit new clubs lightly; the implications for pooling and reinsurance economics are significant and a new entrant must satisfy the existing members of its long-term capital, governance and underwriting standards.
Non-Group P&I providers — including fixed-premium Lloyd’s syndicates, certain regional mutuals and dedicated small craft clubs — serve segments of the market not addressed by Group clubs. These providers do not benefit from the Group’s pool or reinsurance contract and so typically offer lower limits at lower premium per gross tonne.
The Group’s structure should be distinguished from the various national P&I associations historically maintained for state-flag fleets (now largely defunct), and from war risks associations such as the UK Mutual War Risks Association and the Hellenic War Risks Association, which provide separately structured mutual cover for war and related risks not covered by P&I.
A Group club bears the first US$10m of a US$120m claim arising from a large container vessel grounding causing wreck removal and pollution liabilities. The next US$70m is allocated to the Group pool and shared among the twelve clubs in proportions reflecting their share of pool entries and claims experience for the year. The balance of US$40m falls within the first layer of the Group’s General Excess Loss Reinsurance Contract and is paid by the participating reinsurers. The total loss is absorbed without any single club or any single member facing an unmanageable burden. Numbers in this example are illustrative.
