Self-insurance is the deliberate decision to retain a financial risk internally, absorbing potential losses from one's own resources, rather than transferring that risk to a commercial insurer.
Self-insurance is not simply the absence of insurance; it is a conscious risk management posture. A family or business identifies a category of potential loss, concludes that purchasing commercial coverage is uneconomical or unnecessary given their financial strength, and sets aside resources, formally or informally, to cover losses if they occur. At high wealth levels, self-insuring certain routine or bounded risks can be rational: paying commercial premiums for losses a family could easily absorb may represent a poor expected-value trade. The topic connects naturally to broader risk budgeting and capital preservation frameworks families use to think about downside scenarios.
Self-insurance exists on a spectrum. At its most informal, it simply means going without coverage and accepting the risk. More structured approaches involve formal reserve funds, sometimes held in a dedicated account or entity, earmarked for specific categories of loss. A captive insurer is one formalized version of self-insurance that introduces regulatory structure and potential tax benefits.
The central danger of self-insurance is underestimating the size, frequency, or correlation of retained risks. A hypothetical family that self-insures its art collection, several properties, and a fleet of vehicles may believe each individual risk is manageable, until a single catastrophic event, such as a fire, triggers simultaneous losses across multiple categories. Families considering self-insurance for any material risk should work with a qualified risk management professional to model potential loss scenarios honestly before reducing or eliminating coverage.
