💡 Selecting all-risk coverage carries meaningful implications at every stage of the insurance transaction. [[Definition:Insurance broker | Brokers]] who place programs on an all-risk basis can offer their clients greater certainty of recovery, which is especially valuable for complex [[Definition:Commercial risk | commercial risks]] such as large real estate portfolios or manufacturing operations where unforeseen loss scenarios are difficult to catalog in advance. On the carrier side, [[Definition:Actuarial analysis | actuarial teams]] must model a wider tail of potential loss events, and [[Definition:Reinsurance | reinsurance]] purchasing strategies may need to account for the additional volatility that open-peril books can introduce into aggregate results. |

🌐 All-risk coverage — sometimes styled "all-risks" — is a form of property or marine insurance that covers loss or damage from any peril unless that peril is specifically excluded in the policy wording. This "open perils" approach stands in contrast to "named perils" policies, which list every covered cause of loss explicitly and provide no protection against anything not on that list. The distinction is fundamental in insurance contract design worldwide: all-risk forms dominate commercial property, inland marine, and ocean cargo markets from Lloyd's to Asian hubs like Singapore and Hong Kong, while named-perils structures remain more common in certain personal lines and developing markets.
📖 Under an all-risk policy, the burden of proof shifts in a way that materially affects claims outcomes. The policyholder need only demonstrate that a covered loss occurred — that the property was damaged or destroyed — without having to prove the specific peril that caused it. The insurer, in turn, bears the burden of showing that a policy exclusion applies if it wishes to deny the claim. Common exclusions in all-risk forms include war, nuclear hazard, wear and tear, inherent vice, and — increasingly after a wave of cyber-related property losses — certain technology-driven perils. Flood and earthquake are also frequently excluded and written separately. The breadth of coverage means that underwriters pay close attention to the exclusion schedule, because it is the exclusion language — not the insuring agreement — that defines the effective boundaries of protection. Markets differ in their standard exclusion sets: U.S. commercial property forms issued by the ISO reflect one tradition, while Lloyd's market wordings and local policy forms in Continental Europe or Japan follow their own conventions.
💡 All-risk coverage matters enormously to commercial and industrial insureds because it eliminates the gap risk inherent in named-perils policies — the possibility that an unanticipated cause of loss falls outside the enumerated list. For a multinational corporation purchasing a global property program, all-risk wording provides a broad safety net that accommodates the diverse and sometimes unpredictable hazards faced across different geographies.
