<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📄 &#039;&#039;&#039;Structured security&#039;&#039;&#039; is a financial instrument created by pooling and tranching underlying exposures — and in the insurance world, those exposures are typically [[Definition:Insurance risk | insurance risks]], [[Definition:Premium | premium]] flows, or [[Definition:Loss reserve | loss reserves]] — into securities with varying risk-return profiles that can be sold to [[Definition:Capital markets | capital markets]] investors. [[Definition:Catastrophe bond | Catastrophe bonds]], [[Definition:Insurance-linked security (ILS) | insurance-linked securities]], and securitized [[Definition:Life settlement | life settlement]] portfolios are the most recognizable forms of structured securities originating from the insurance sector.<br /> <br /> ⚙️ Construction of a structured security generally involves an [[Definition:Insurance carrier | insurer]] or [[Definition:Reinsurance | reinsurer]] transferring a defined block of risk to a [[Definition:Special purpose vehicle (SPV) | special purpose vehicle]], which then issues multiple tranches of notes — senior, mezzanine, and equity — each absorbing losses in reverse order of seniority. Investors in the senior tranche accept a lower yield in exchange for greater protection against loss, while equity tranche holders bear the first losses but earn a higher coupon. [[Definition:Credit rating agency | Rating agencies]] assign grades to each tranche based on modeled [[Definition:Expected loss | expected loss]] and [[Definition:Attachment point | attachment point]] analysis. Collateral mechanics, [[Definition:Trigger (insurance) | trigger]] definitions (indemnity, parametric, or modeled loss), and legal isolation of the SPV from the [[Definition:Cedent | ceding company&#039;s]] [[Definition:Insolvency | insolvency]] estate are critical structural elements.<br /> <br /> 💡 Structured securities give insurers a powerful tool to manage [[Definition:Peak peril | peak peril]] concentrations and optimize their [[Definition:Risk-based capital (RBC) | risk-based capital]] positions. When a carrier securitizes a layer of [[Definition:Catastrophe risk | catastrophe exposure]], it effectively converts an illiquid underwriting liability into a tradeable instrument, freeing up balance sheet capacity for new business. For investors — typically institutional players like pension funds and specialized [[Definition:Insurance-linked security (ILS) | ILS]] funds — these securities offer returns largely uncorrelated with broader financial markets, making them an attractive diversification tool. The 2017 and 2022 catastrophe loss years tested this market significantly, refining investor expectations around trapped collateral and loss development timelines.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Insurance-linked security (ILS)]]<br /> * [[Definition:Catastrophe bond]]<br /> * [[Definition:Special purpose vehicle (SPV)]]<br /> * [[Definition:Tranche]]<br /> * [[Definition:Securitization]]<br /> * [[Definition:Collateralized reinsurance]]<br /> {{Div col end}}</div>
