American International Group, Inc. (AIG) is a global insurance organization founded in 1919 and headquartered in New York City. AIG provides a range of property casualty insurance and other financial services across more than 70 countries. Following the 2022 IPO of Corebridge Financial (formerly AIG Life & Retirement), AIG’s remaining investment portfolio is approximately $270 billion, focused primarily on its general insurance operations.
Investment Strategy
AIG’s investment portfolio is predominantly composed of fixed income securities, including investment-grade corporate bonds, government and agency securities, mortgage-backed securities, and asset-backed securities. The portfolio is managed to generate stable investment income while maintaining appropriate liquidity and credit quality to support AIG’s insurance obligations.
A defining feature of AIG’s recent investment strategy is its strategic partnership with Blackstone, established in 2020. Under this arrangement, Blackstone manages a substantial portion of AIG’s investment assets, with a focus on private credit origination, structured finance, and alternative asset strategies. This partnership has allowed AIG to access Blackstone’s origination capabilities and enhance portfolio yield relative to traditional fixed income benchmarks.
Private Markets Approach
AIG allocates approximately 10% of its investment portfolio to alternative investments, including private equity, private credit, real estate, and hedge funds. The Blackstone relationship has been instrumental in growing AIG’s private credit exposure, with investments spanning direct lending, commercial real estate debt, and structured credit.
In private equity, AIG maintains commitments to a diversified set of fund managers across buyout, growth, and secondary strategies. The company has historically invested alongside large-cap GPs and has the capacity for meaningful co-investments. Real estate exposure includes both equity investments and mortgage loans, with Blackstone managing a significant portion of the real estate credit portfolio.
AIG’s investment approach emphasizes risk management, capital efficiency under insurance regulatory frameworks, and diversification across geographies and strategies. The company’s ongoing transformation has included a sharpened focus on investment returns as a driver of overall profitability.
