🌊 '''Named storm deductible''' is a specialized [[Definition:Deductible | deductible]] provision found in [[Definition:Property insurance | property insurance]] policies that applies a separate — and typically much larger — deductible when damage is caused by a [[Definition:Named storm | named storm]], meaning a tropical or subtropical weather system officially designated by a meteorological authority. Unlike a standard flat-dollar deductible, a named storm deductible is usually expressed as a percentage of the insured property's total value, commonly ranging from 1% to 10% depending on the geographic location, [[Definition:Insurance carrier | carrier]], and policy terms. This structure is prevalent in hurricane-exposed states along the Gulf Coast and Atlantic seaboard.

⚙️ The mechanics are straightforward but carry serious financial weight. Once a meteorological agency names a storm and that storm causes covered damage to an insured property, the percentage-based deductible replaces the policy's standard deductible for that event. For example, on a home insured for $500,000 with a 5% named storm deductible, the policyholder would bear the first $25,000 of loss before the [[Definition:Insurance carrier | insurer's]] obligation begins. Many policies define the trigger period carefully — specifying that the named storm deductible applies from a set number of hours before the storm's arrival through a defined period after it passes — to prevent disputes over whether damage resulted from the named event or from unrelated weather.

💡 These deductibles emerged as a direct response to the escalating [[Definition:Catastrophe loss | catastrophe losses]] insurers faced from major hurricanes in the 1990s and 2000s. By shifting a meaningful share of loss back to the policyholder during the costliest events, [[Definition:Underwriter | underwriters]] can maintain capacity in high-risk coastal markets that might otherwise become uninsurable at affordable [[Definition:Premium | premiums]]. State [[Definition:Insurance regulation | regulators]] closely oversee named storm deductible requirements — some states mandate specific disclosure language so consumers understand when and how this deductible applies. For [[Definition:Reinsurer | reinsurers]] and [[Definition:Catastrophe modeling | catastrophe modelers]], the prevalence of percentage-based named storm deductibles in a portfolio materially affects projected net losses and must be accurately reflected in exposure analyses.
