<p><b>New page</b></p><div>⚠️ '''Subprime''' refers, within the insurance and financial services landscape, to borrowers, assets, or risk segments that fall below standard creditworthiness thresholds and carry elevated probabilities of default or loss. The term gained its most notorious prominence during the 2007–2008 financial crisis, when the collapse of subprime mortgage-backed securities triggered catastrophic losses not only for banks but for major insurers — most dramatically [[Definition:American International Group (AIG)|AIG]], whose Financial Products unit had written vast volumes of [[Definition:Credit default swap|credit default swaps]] guaranteeing subprime-linked [[Definition:Structured finance|structured finance]] instruments. For the insurance industry, "subprime" is therefore not merely a credit classification but a cautionary reference point that reshaped [[Definition:Enterprise risk management|enterprise risk management]], regulatory oversight, and the industry's understanding of interconnected [[Definition:Systemic risk|systemic risk]].<br />
<br />
🔗 The mechanics of subprime exposure in insurance operated through several channels. Insurers and [[Definition:Reinsurer|reinsurers]] held subprime mortgage-backed securities and [[Definition:Collateralized debt obligation|collateralized debt obligations]] (CDOs) in their [[Definition:Investment portfolio|investment portfolios]], attracted by the yield premium these instruments offered over conventional bonds. [[Definition:Financial guaranty insurance|Financial guaranty insurers]] — known as [[Definition:Monoline insurer|monolines]] — such as MBIA and Ambac directly insured tranches of subprime securitizations, effectively wrapping them with an insurer's credit guarantee. AIG's credit default swap portfolio represented yet another pathway, functioning as a form of unregulated [[Definition:Credit insurance|credit insurance]] that concentrated enormous contingent liabilities on a single balance sheet. When subprime mortgage defaults surged, correlations that [[Definition:Risk model|risk models]] had assumed to be low turned out to be dangerously high, and the resulting losses overwhelmed the capital buffers of exposed insurers. AIG required a U.S. government bailout exceeding $180 billion, and several monoline insurers were downgraded to junk status or entered [[Definition:Run-off|run-off]].<br />
<br />
🏛️ The subprime crisis fundamentally altered how regulators and the insurance industry approach concentrated [[Definition:Credit risk|credit risk]] and [[Definition:Counterparty risk|counterparty risk]]. In the United States, the crisis contributed to the passage of the Dodd-Frank Act, which designated certain large insurers as [[Definition:Systemically important financial institution (SIFI)|systemically important financial institutions]] and subjected them to enhanced prudential supervision. Globally, the International Association of Insurance Supervisors (IAIS) developed the [[Definition:Insurance capital standard (ICS)|Insurance Capital Standard]] partly in response to the realization that insurance groups could transmit financial shocks across borders. [[Definition:Solvency II|Solvency II]] in Europe incorporated explicit spread risk and concentration risk charges designed to penalize heavy exposure to lower-rated or complex structured assets. Beyond regulation, the episode prompted insurers to strengthen [[Definition:Investment risk management|investment risk governance]], diversify asset allocations, and apply more skeptical scrutiny to external credit ratings — recognizing that subprime assets rated investment-grade by [[Definition:Rating agency|rating agencies]] had proven to be anything but safe.<br />
