Definition:Floating policy
📋 Floating policy is a type of property insurance or marine insurance contract that provides a single blanket of coverage over goods or property whose quantity, value, or location fluctuates over time, rather than attaching to a fixed, scheduled list of items. It is most commonly encountered in inland marine, ocean cargo, and stock-throughput contexts, where an insured — such as a manufacturer, wholesaler, or logistics company — holds inventory that moves continuously between warehouses, transit routes, and customer sites.
🔄 Under a floating policy, the sum insured is set at a maximum limit representing the greatest value likely to be at risk at any one time, and the insured periodically declares the actual value of goods covered — often monthly or quarterly — so that the premium can be adjusted accordingly. This declaration mechanism distinguishes the floating policy from a fixed-value contract: the insurer's exposure tracks the insured's real economic position rather than a static estimate. In markets governed by the UK's Marine Insurance Act 1906, the floating policy has a long statutory heritage, and its principles have been adopted in many Commonwealth jurisdictions. Modern equivalents appear in open cover arrangements used extensively in global cargo insurance, where each shipment attaches automatically to the master contract once declared.
💡 For businesses with volatile inventories, a floating policy eliminates the administrative burden and coverage gaps that would arise from purchasing separate policies each time goods move or stock levels change. It also benefits underwriters, who gain a steady book of premium tied to a client's throughput rather than insuring discrete shipments on an ad hoc basis. Because average clauses or coinsurance provisions often apply, the insured has a strong incentive to declare values accurately; under-declaration can result in proportional reduction of claims payments. Across jurisdictions — from Lloyd's cargo syndicates to Asian marine markets in Singapore, Hong Kong, and Tokyo — the floating policy remains a foundational structure for insuring goods in motion.
