Definition:All-risks
🛡️ All-risks is an insurance coverage concept describing a policy structure that protects the insured against all causes of physical loss or damage unless a specific exclusion applies. In the insurance industry, the term signals a fundamentally different approach from named-peril coverage: rather than listing every covered event, an all-risks form presumes coverage and then carves out defined exceptions. This framework is employed across multiple lines of business, including property insurance, marine insurance, cargo insurance, and certain inland marine and fine art policies.
⚖️ Under an all-risks structure, the policyholder need only demonstrate that a covered loss occurred — the burden of proof then shifts to the insurer to show that the cause falls within an exclusion. Common exclusions typically address inherent vice, gradual deterioration, wear and tear, intentional acts, nuclear hazards, war, and — in many modern wordings — cyber events and pandemic-related losses. The specific exclusion language varies considerably by jurisdiction and market: Lloyd's and London market wordings have their own conventions, U.S. commercial property forms follow ISO or manuscript approaches, and Asian markets often adapt London or local standard clauses. Underwriters price all-risks coverage at higher premiums than named-peril equivalents because the scope of potential claims is inherently broader.
💡 The practical significance of the all-risks concept extends well beyond policy wording. It shapes how claims adjusters investigate losses, how courts interpret coverage disputes, and how reinsurers structure their treaty protections. In jurisdictions such as England, the United States, and Australia, decades of case law have refined the boundaries of what "all risks" truly encompasses — for example, whether defective design constitutes an insured peril or an excluded one. For risk managers and brokers advising commercial clients, understanding the all-risks framework is essential to ensuring that coverage gaps are identified and addressed, whether through policy endorsements, difference-in-conditions wraps, or bespoke manuscript wordings.
