In the early 2000s, investors sought safe returns after the tech bubble burst. Mortgages became an attractive option as they offered regular interest payments and a tangible asset (the house) in case of default. Investment banks began purchasing large volumes of mortgages, pooling them, and selling shares to investors as mortgage-backed securities (MBS). The government also supported this trend through Fannie Mae and Freddie Mac, leading to a surge in mortgage lending and home buying.
Companies, including insurers, wanted to capitalize on this boom. Insurers started selling credit default swaps (CDS), derivatives that paid out if a mortgage borrower defaulted. Speculators also bought these policies, leading to an excessive amount of credit being insured, far exceeding the actual funds available to cover potential payouts. This system relied heavily on rising housing prices.
As lenders sold their loans, they lost the incentive to assess risk carefully. The high demand for mortgages led them to offer loans to borrowers with poor credit scores and low incomes, known as subprime mortgages, many of which had predatory terms. Investment banks continued to buy these risky mortgages, integrating them into MBSs and collateralized debt obligations (CDOs), often misrepresenting their safety. Complex derivatives like synthetic CDOs further amplified the betting on mortgage payments.
Despite the increasing risk, rating agencies, paid by the banks they rated, continued to assign high safety ratings (like Triple-A) to these toxic assets. This created a system where lenders, investment bankers, and rating agencies all neglected their responsibilities and disregarded the mounting risks, creating a fragile financial ecosystem.
In October 2007, subprime borrowers began defaulting, leading to a rapid increase in foreclosures. Investment banks flooded the market with repossessed homes, causing housing prices to plummet unexpectedly in 2008. This triggered a domino effect, with finance companies heavily invested in real estate suffering massive losses. 70% of CDOs, despite high ratings, defaulted, and insurers faced impossible payouts.
Banks, lenders, and insurers began to collapse. On September 15th, Lehman Brothers, a major investment bank, declared bankruptcy. Widespread panic led investors to withdraw from the markets, causing the Dow Jones to lose a significant portion of its value. Companies lost access to vital financing, and countries tied to the US were swept into the disaster. By 2009, the global economy stalled, resulting in millions of job losses and a prolonged recession, with financial institutions, despite causing the crisis, receiving the most government aid.
While the recession technically ended in June 2009, its impact was felt for years. The Dodd-Frank Act was introduced in 2010 to regulate financial institutions and prevent similar crises, serving as a reminder that greed should not overshadow common sense and decency in the financial world.
