<p><b>New page</b></p><div>⚠️ '''Interest rate risk''' is the exposure an [[Definition:Insurance carrier | insurer]] faces when changes in market interest rates create a mismatch between the value of its [[Definition:Investment portfolio | investment assets]] and its [[Definition:Policy liability | insurance liabilities]]. Because insurers are among the largest institutional holders of fixed-income securities, and because the present value of their future [[Definition:Insurance claim | claim]] obligations is highly sensitive to discount rate assumptions, interest rate movements can materially affect [[Definition:Solvency | solvency]], [[Definition:Profitability | profitability]], and reported [[Definition:Earnings | earnings]] in ways that equity-market volatility often cannot.<br />
<br />
⚙️ The mechanism is rooted in [[Definition:Asset-liability management (ALM) | asset-liability management]]. An insurer holds bonds whose market value falls when rates rise and increases when rates drop. Simultaneously, the present value of its liabilities moves in the opposite direction — falling when discount rates rise, increasing when they decline. If the [[Definition:Duration | duration]] of assets closely matches the duration of liabilities, these effects largely offset each other. Mismatches arise when, for example, a [[Definition:Life insurance | life insurer]] sells long-duration [[Definition:Annuity | annuity]] products but invests in shorter-duration bonds, leaving it exposed if rates decline and it must reinvest at lower yields. [[Definition:Actuarial science | Actuaries]] and [[Definition:Chief risk officer (CRO) | risk officers]] monitor metrics such as [[Definition:Duration gap | duration gap]], [[Definition:Convexity | convexity]], and [[Definition:Key rate duration | key rate duration]] to quantify and manage this exposure.<br />
<br />
🛡️ Regulatory regimes treat interest rate risk as a core pillar of insurer risk management. Under [[Definition:Solvency II | Solvency II]], insurers must hold a specific [[Definition:Solvency capital requirement (SCR) | solvency capital]] charge for interest rate risk, calculated by stressing yield curves upward and downward. [[Definition:International Financial Reporting Standards (IFRS) | IFRS 17]] further heightens transparency by requiring insurers to present the impact of discount rate changes on liability valuations directly in financial statements. Beyond regulatory compliance, effective interest rate risk management safeguards policyholders: an insurer that fails to hedge this risk adequately may find itself unable to honor long-dated [[Definition:Guaranteed return | guarantees]] or forced to realize losses on its bond portfolio at precisely the wrong moment. Hedging tools — including interest rate swaps, [[Definition:Derivative | derivatives]], and liability-driven investment strategies — are now standard practice for well-capitalized carriers.<br />
