Definition:American International Group
🏛 American International Group (AIG) is one of the most consequential insurance organizations in modern history, with roots stretching back to 1919 when Cornelius Vander Starr founded an insurance agency in Shanghai, China. From its Asian origins, the company grew into a sprawling global conglomerate spanning property and casualty insurance, life insurance, retirement services, and financial services. AIG became synonymous with both the extraordinary reach of American insurance enterprise abroad and, later, the systemic risks that interconnected financial institutions can pose to global markets. Its corporate identity was long shaped by Maurice "Hank" Greenberg, who led the company for nearly four decades and transformed it into one of the largest insurers in the world by gross written premium and asset base.
⚠️ AIG's defining historical episode came during the 2008 global financial crisis, when its Financial Products unit's massive exposure to credit default swaps tied to mortgage-backed securities brought the company to the brink of collapse. The U.S. government intervened with a bailout that ultimately totaled roughly $182 billion, making it the largest government rescue of a private company in history. This event reshaped regulatory thinking worldwide about systemic risk in insurance and contributed directly to the development of frameworks for identifying global systemically important insurers (G-SIIs). The crisis also prompted significant reforms in how regulators scrutinize non-traditional and non-insurance activities conducted by insurance groups, influencing bodies such as the International Association of Insurance Supervisors (IAIS) and national authorities alike.
🔄 In the years following the crisis, AIG undertook a prolonged restructuring, divesting major business units — including its international life insurance operations, which were spun off as Corebridge Financial — to simplify its corporate structure and refocus on core commercial and personal property-casualty operations. The company's trajectory illustrates enduring lessons for the insurance industry about the dangers of excessive leverage, opaque risk exposures, and the blurring of insurance and capital markets activities. AIG remains a major global insurer with significant operations across specialty lines, excess and surplus lines, and multinational commercial programs, and its history continues to inform how regulators, rating agencies, and market participants think about enterprise risk management and corporate governance in insurance.
