<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>⚠️ &#039;&#039;&#039;Mortality risk&#039;&#039;&#039; is the uncertainty that actual death rates among a pool of insured lives will diverge from the assumptions an [[Definition:Insurance carrier | insurer]] used when pricing and reserving for [[Definition:Life insurance | life insurance]], [[Definition:Annuity | annuity]], or [[Definition:Pension fund | pension]] obligations. It cuts in two directions: for products that pay upon death — such as [[Definition:Term life insurance | term life]] or [[Definition:Whole life insurance | whole life]] policies — higher-than-expected mortality means accelerated [[Definition:Insurance claim | claim]] payouts, while for [[Definition:Annuity | annuity]] products that pay as long as the [[Definition:Annuitant | annuitant]] lives, lower-than-expected mortality (i.e., longer lives) creates [[Definition:Longevity risk | longevity risk]].<br /> <br /> 🔄 Managing mortality risk begins with granular [[Definition:Underwriting | underwriting]] — gathering medical histories, lab results, and lifestyle data to classify applicants into risk tiers that align with the [[Definition:Mortality rate | mortality rates]] embedded in pricing. Beyond individual selection, insurers diversify mortality risk by writing large, geographically dispersed portfolios and by ceding peak exposures through [[Definition:Reinsurance | reinsurance]] arrangements such as [[Definition:Yearly renewable term (YRT) reinsurance | yearly renewable term]] or [[Definition:Coinsurance | coinsurance]] treaties. [[Definition:Actuary | Actuaries]] also perform regular [[Definition:Experience study | experience studies]] comparing actual to expected deaths, feeding the results back into assumption updates and [[Definition:Reserve adequacy testing | reserve adequacy tests]].<br /> <br /> 💡 The broader financial system has a stake in how well insurers handle mortality risk. Catastrophic mortality events — pandemics, natural disasters with mass casualties — can simultaneously stress many carriers, which is why [[Definition:Capital markets | capital-market]] instruments like [[Definition:Mortality bond | mortality bonds]] and [[Definition:Insurance-linked security (ILS) | insurance-linked securities]] have emerged to transfer extreme tail risk to investors. Regulatory frameworks, including the [[Definition:Risk-based capital (RBC) | risk-based capital]] system in the United States and [[Definition:Solvency II | Solvency II]] in Europe, assign explicit capital charges for mortality risk, ensuring carriers hold buffers commensurate with the uncertainty they carry on their balance sheets.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Mortality rate]]<br /> * [[Definition:Longevity risk]]<br /> * [[Definition:Morbidity risk]]<br /> * [[Definition:Reinsurance]]<br /> * [[Definition:Mortality table]]<br /> * [[Definition:Insurance-linked security (ILS)]]<br /> {{Div col end}}</div>
