Reviewing the history of American International Group (AIG) reveals a narrative of unprecedented global expansion, a catastrophic financial collapse during the 2008 crisis, and a decade-long restructuring process. Founded in 1919, the firm evolved from a small Shanghai agency into a global insurance powerhouse, ultimately surviving a federal bailout to emerge as a leaner, specialized entity by 2026.
The Foundations of a Global Empire (1919–1945)
The story of AIG began not in the financial districts of New York or London, but in the bustling port of Shanghai, China. In 1919, an American entrepreneur named Cornelius Vander Starr established a modest insurance agency called American Asiatic Underwriters (AAU). Starr’s vision was distinct: he sought to bring Western insurance practices to Asian markets, a move that was considered highly unconventional at the time.
During these formative years, Starr focused on localizing the business. Unlike other foreign firms that relied on expatriate managers, AAU hired and trained local staff, which allowed the company to integrate deeply into the Chinese economy. By 1921, Starr expanded into life insurance with the creation of Asia Life Insurance Company. The success in China provided the capital and operational blueprint for global expansion.
By 1926, Starr opened his first office in the United States, establishing American International Underwriters (AIU) in New York. This served as a bridge between U.S. insurers and foreign risks. Throughout the 1930s and during the Second World War, the company faced significant geopolitical upheaval. The Japanese invasion of China forced the relocation of operations, but the decentralized nature of Starr’s growing network allowed the firm to survive the era’s volatility, eventually shifting its primary headquarters to New York.
The Era of Maurice "Hank" Greenberg (1967–2005)
If Cornelius Vander Starr built the foundation, Maurice "Hank" Greenberg built the skyscraper. Taking the reins in 1967, Greenberg transformed AIG into a modern financial titan. Under his leadership, the company pursued an aggressive strategy of diversification and global dominance that lasted nearly four decades.
AIG went public in 1969, a move that provided the liquidity necessary for massive acquisitions and the development of sophisticated financial products. Greenberg’s philosophy was rooted in "underwriting profit"—the idea that the insurance business itself should be profitable, rather than relying solely on investment income from premiums.
Key developments during this period included:
- Expansion into Financial Services: AIG moved beyond traditional property and casualty insurance into areas like aircraft leasing (ILFC) and consumer finance.
- The Creation of AIGFP: In 1987, the company established AIG Financial Products. This subsidiary was designed to apply AIG’s AAA credit rating to the burgeoning world of derivatives and complex financial instruments.
- Global Market Penetration: AIG became the first foreign insurer to be granted a license to operate in post-reform China in the early 1990s, returning to its roots with massive success.
By the early 2000s, AIG was one of the largest companies in the world, with operations in over 130 countries and a market capitalization that made it a cornerstone of the Dow Jones Industrial Average. However, the complexity of its global structure and the risks lurking within its financial products division were beginning to create systemic vulnerabilities.
The 2008 Financial Crisis and the $182 Billion Bailout
The most pivotal chapter in the AIG 100 years in review is undoubtedly the 2008 financial crisis. The company’s downfall was not caused by its traditional insurance subsidiaries—which remained largely profitable and well-capitalized—but by a specific product line within AIG Financial Products (AIGFP): Credit Default Swaps (CDS).
AIGFP had written billions of dollars in CDS contracts, essentially acting as insurance for mortgage-backed securities. When the U.S. housing market collapsed and subprime mortgages defaulted, AIG was required to post massive amounts of collateral to its counterparties (major global banks). Because AIG’s credit rating was downgraded, the collateral calls became unsustainable.
In September 2008, AIG faced a liquidity crisis so severe that it threatened to topple the entire global financial system. Because AIG was connected to almost every major bank worldwide through its CDS contracts, the U.S. government deemed it "too big to fail."
The Bailout Structure
The Federal Reserve and the U.S. Treasury intervened with a series of rescue packages that eventually totaled approximately $182.3 billion. This intervention was not a gift; it came with high interest rates and the government taking a nearly 80% equity stake in the company. To repay the debt, AIG was forced to begin a massive fire sale of its most prized international assets.
| Year | Key Event | Impact on AIG |
|---|---|---|
| 2008 | Federal Reserve Credit Facility | Initial $85 billion loan to prevent immediate bankruptcy. |
| 2009 | Restructuring of Debt | Conversion of debt to equity; government stake increases. |
| 2010 | Sale of ALICO and AIA IPO | Sale of major life insurance units to pay down the Treasury. |
| 2012 | Final Repayment | U.S. Treasury exits AIG, realizing a $22.7 billion profit on the bailout. |
| 2017 | SIFI Designation Removal | Regulators declare AIG no longer a systemic risk to the economy. |
The Road to Recovery and Repayment (2012–2019)
By late 2012, AIG had defied expectations by fully repaying the U.S. government. The repayment was facilitated by the IPO of AIA (its Asian life insurance giant) and the sale of American Life Insurance Company (ALICO) to MetLife. While the company emerged from the crisis intact, it was significantly smaller and under intense regulatory scrutiny.
The years leading up to its 100th anniversary in 2019 were defined by a struggle for identity. The company went through several CEOs, including Robert Benmosche, who is credited with stabilizing the firm, and Peter Hancock, who focused on data-driven underwriting but struggled with activist investors calling for the company to be broken up.
In 2017, Brian Duperreault took over as CEO. A protégé of Greenberg, Duperreault shifted the focus back to "underwriting excellence." He halted the aggressive share buybacks favored by his predecessors and instead invested in technology and traditional insurance expertise. This era marked the transition from "survival mode" to "strategic growth."
AIG in the Modern Era: 2020 to 2026
As we look at AIG from the vantage point of 2026, the company has completed one of the most significant structural transformations in corporate history. The defining move of the early 2020s was the decision to separate the Life and Retirement business from the General Insurance business.
The Corebridge Financial Spin-off
Recognizing that the market valued life insurance and general insurance differently, AIG initiated the separation of its Life and Retirement unit, rebranded as Corebridge Financial. This process, which began with an IPO in 2022 and concluded with a final divestiture of remaining shares by 2025, allowed AIG to become a "pure-play" property and casualty (P&C) insurer.
Operational Focus in 2026
In 2026, AIG operates with a streamlined focus on three primary pillars:
- General Insurance: Providing high-capacity coverage for global corporations, including specialized lines like cyber insurance, marine, and aviation.
- AIG 200 Legacy: The "AIG 200" program, launched in 2019, has fully modernized the company's backend infrastructure, replacing decades-old legacy systems with cloud-based AI integration.
- Risk Engineering: Utilizing satellite imagery and IoT sensors to help clients mitigate risks before claims occur, moving from a "detect and repair" model to a "predict and prevent" model.
Under the leadership of Peter Zaffino, who succeeded Duperreault, the company has regained its reputation for financial stability. By 2026, AIG’s combined ratio—a key metric of insurance profitability—has consistently outperformed industry averages, signaling that the focus on disciplined underwriting has paid off.
Technical Analysis: Understanding the AIG Business Model
To truly review AIG’s 100-year journey, one must understand the mechanics of its current operations compared to its pre-2008 structure. The AIG of 2026 is fundamentally different from the AIG of 2006.
From Financial Engineering to Risk Transfer
The pre-2008 AIG relied heavily on "spread compression" and financial engineering through its Financial Products division. Essentially, it was using its balance sheet to act as a bank. The AIG of 2026 is strictly a risk-transfer entity. It earns revenue through premiums and manages that capital through conservative investment portfolios, primarily in high-grade fixed-income securities.
Global Footprint and Reinsurance
AIG remains one of the few insurers capable of handling "multinational programs." A company operating in 50 countries can have a single master policy with AIG that complies with local regulations in every jurisdiction. This "global network" is AIG's most durable competitive advantage. Additionally, AIG has become a sophisticated user of reinsurance, transferring its own peak risks to secondary markets to ensure that a single catastrophe (like a major hurricane or earthquake) cannot threaten the company’s solvency.
Frequently Asked Questions
Is AIG still the same company it was before the 2008 crisis?
While it retains the name, AIG is fundamentally different. It is significantly smaller, having sold off major units like AIA, ALICO, and its aircraft leasing business. Most importantly, it no longer operates the high-risk derivatives business (AIGFP) that caused its collapse. By 2026, it is primarily a Property and Casualty insurer.
How did AIG manage to pay back $182 billion?
Repayment was achieved through a massive divestiture program. AIG sold non-core assets globally and took its massive Asian life insurance business, AIA, public on the Hong Kong Stock Exchange. The U.S. government actually made a profit of approximately $22.7 billion on the total rescue package through interest and the sale of AIG stock.
What is the significance of the Corebridge Financial separation?
The separation of Corebridge Financial (the Life and Retirement business) allowed AIG to simplify its financial reporting and focus exclusively on General Insurance. Investors generally prefer pure-play companies because they are easier to value and have different risk profiles than diversified conglomerates.
Who are AIG’s primary competitors in 2026?
In the global commercial insurance space, AIG’s primary competitors include Chubb, Zurich Insurance Group, Allianz, and Travelers. In specialized reinsurance and excess lines, they often compete with Lloyd’s of London syndicates and Berkshire Hathaway’s insurance operations.
Does AIG still operate in China where it was founded?
Yes, AIG maintains a significant presence in China. After being forced out during the mid-20th century, it returned in the 1990s. While it sold its massive AIA unit during the bailout, AIG continues to provide commercial insurance services to multinational and local corporations in the Chinese market.
Final Perspective and Next Steps
The century-long trajectory of AIG serves as a masterclass in both the heights of corporate ambition and the perils of systemic complexity. From a Shanghai startup to a global pariah, and finally to a stabilized industry leader in 2026, the company’s survival is a testament to the essential nature of the insurance industry.
For investors and policyholders, the "new" AIG represents a shift toward transparency and disciplined risk management. If you are evaluating AIG today, focus on its combined ratio and its capital adequacy ratios, as these are the primary indicators of its health as a pure-play insurer. The lessons of the 2008 crisis have been deeply institutionalized, resulting in a firm that prioritizes sustainability over rapid, unhedged expansion.
