Meaning and Importance of Insurance

Every business and every individual faces the possibility of an uncertain, unwanted future event — fire destroying a warehouse, a ship sinking with its cargo, an accident, illness, or premature death. Insurance is a contract (a policy) under which one party (the insurer, typically an insurance company) promises, in exchange for a payment called the premium, to compensate another party (the insured) for a specified financial loss that may result from a defined uncertain event.

Insurance works on the principle of risk-sharing/pooling: a large number of people, each individually exposed to the same kind of risk, contribute a relatively small premium into a common fund managed by the insurer; only a few of them will actually suffer the loss in any given period, and the insurer pays those few out of the pooled fund built up by the contributions of everyone. In this way, insurance does not prevent the loss from occurring, but it spreads the financial burden of a loss across many people, so that no single unlucky individual has to bear the entire loss alone.

As one of the recognised auxiliaries to trade (alongside transportation, warehousing, banking and advertising, studied elsewhere in this unit), insurance gives businesses and individuals the confidence to undertake risk-bearing activities — building factories, shipping cargo, extending credit — knowing that a genuinely ruinous loss can be financially absorbed rather than falling entirely on one party at the worst possible moment.
