Definition:All risks coverage
📦 All risks coverage is a broad form of insurance policy wording used predominantly in marine and property insurance that covers loss or damage from any fortuitous cause unless specifically excluded. Rather than listing every covered peril — as a named-perils policy does — an all risks policy inverts the structure: everything is covered unless the policy language carves it out. This approach originated in marine cargo insurance, where the unpredictable nature of ocean transit made exhaustive peril enumeration impractical, and it has since become standard across cargo, inland transit, and many commercial property lines worldwide. The Institute Cargo Clauses (A), maintained by the International Underwriting Association, represent the most widely recognized all risks form in international trade, while equivalent wordings exist under American Institute conditions and in domestic markets across Asia and Continental Europe.
🔍 Despite its name, all risks coverage does not actually cover every conceivable risk. Every all risks policy contains exclusions — typically for inherent vice, ordinary wear and tear, delay, willful misconduct of the insured, inadequate packing, and war or strikes (which are covered separately under their own clauses if purchased). The practical operation of the coverage places the burden of proof differently than a named-perils form: the insured must demonstrate that a loss occurred during the policy period and was fortuitous, but the underwriter bears the burden of proving that an exclusion applies. This allocation of proof is significant in claims handling and litigation. In practice, disputes under all risks wordings often revolve around whether damage resulted from an excluded cause such as inherent vice or ordinary leakage versus an insured fortuitous event. Courts across jurisdictions — from English Commercial Court decisions that influence Lloyd's market practice to rulings in Singapore, Hong Kong, and U.S. federal admiralty courts — have built a substantial body of case law interpreting these boundaries.
🌐 For insurers and reinsurers, writing all risks coverage demands careful attention to exclusion drafting because any gap or ambiguity in the exclusion language effectively becomes a covered peril. This dynamic makes policy wording a critical underwriting tool, and it explains why market bodies invest heavily in maintaining standardized clause sets. From a buyer's perspective, all risks coverage offers the broadest available protection and is typically the default choice for high-value cargo shipments and complex commercial property programs. The distinction between all risks and named-perils forms also affects pricing: all risks coverage commands higher premium rates because the scope of potential exposure is wider. As global supply chains grow more complex and goods transit through multiple jurisdictions, the portability and breadth of all risks wordings have only increased in importance — making them a cornerstone of international cargo insurance programs arranged through brokers in London, Singapore, and other major placement centers.
