What are insurance-linked securities?

Insurance-linked securities are financial instruments whose value is linked to insurance risk, often catastrophe risk. They allow insurers, reinsurers, governments, and other sponsors to transfer risk to capital markets investors.

Insurance-linked securities explained

An insurance-linked security is a financial instrument where returns and principal can depend on insurance loss events. In a simple catastrophe bond, an investor earns a coupon for taking defined catastrophe risk. If a qualifying event occurs and the trigger is met, some or all principal may be used to pay the sponsor.
