View source for Definition:Globally systemically important insurer (G-SII)

🏛️ '''Globally systemically important insurer (G-SII)''' is a designation assigned by the [[Definition:Financial Stability Board (FSB) | Financial Stability Board]] to [[Definition:Insurance carrier | insurers]] whose distress or disorderly failure could trigger widespread disruption across international financial markets. The concept emerged in the aftermath of the 2008 financial crisis, when the near-collapse of [[Definition:American International Group (AIG) | AIG]] demonstrated that a single insurer's interconnectedness with banks, [[Definition:Capital markets | capital markets]], and [[Definition:Counterparty | counterparties]] could amplify systemic shocks far beyond the insurance sector. Beginning in 2013, the FSB, working closely with the [[Definition:International Association of Insurance Supervisors (IAIS) | International Association of Insurance Supervisors (IAIS)]], published an annual list of G-SIIs, subjecting designated firms to enhanced [[Definition:Regulatory capital | regulatory capital]] requirements, heightened supervisory expectations, and mandatory recovery and resolution planning.

⚙️ Identification of G-SIIs relied on a methodology that evaluated insurers across several dimensions: size, global interconnectedness, the degree of non-traditional and non-insurance activities (such as [[Definition:Derivatives | derivatives]] trading and [[Definition:Securities lending | securities lending]]), substitutability in key markets, and complexity of corporate structure. Firms that scored above certain thresholds faced a suite of policy measures, including the requirement to hold [[Definition:Higher loss absorbency (HLA) | higher loss absorbency]] capital, submit [[Definition:Systemic risk management plan | systemic risk management plans]], and develop detailed [[Definition:Resolution plan | resolution plans]] in coordination with their group-wide supervisors. The IAIS served as the standard-setting body, while enforcement fell to national and regional regulators — meaning a European G-SII might face overlapping requirements from [[Definition:Solvency II | Solvency II]] and G-SII policy measures, while a U.S.-domiciled insurer navigated both state-based regulation and Federal Reserve oversight.

📊 The G-SII framework reshaped how regulators and the industry itself think about [[Definition:Systemic risk | systemic risk]] in insurance. In 2019, the FSB announced it would suspend G-SII designations in favor of the IAIS's broader Holistic Framework for systemic risk, which applies activity-based and entity-based supervisory tools across the entire insurance sector rather than singling out named firms. This shift acknowledged that systemic risk in insurance can arise from common exposures and herd behavior — not just individual firm failure. Nevertheless, the G-SII era left a lasting legacy: it accelerated group-wide supervision, embedded [[Definition:Macroprudential regulation | macroprudential]] thinking into insurance oversight, and prompted major insurers to restructure or divest non-core financial activities that had attracted systemic risk scrutiny.
