Question: What were the causes of the 2008 financial crisis?
Answer:
The 2008 financial crisis, also known as the Global Financial Crisis (GFC) or Great Recession, was primarily triggered by the bursting of the U.S. housing bubble and the subsequent subprime mortgage crisis, which spread globally through interconnected financial markets. While there is broad agreement on key factors, economists debate their relative importance. The crisis led to massive bank losses, institution failures (e.g., Lehman Brothers’ bankruptcy in September 2008), stock market crashes, and a severe global recession.
Main Causes:
-
U.S. Housing Bubble and Its Burst (2001–2006 peak, burst starting 2006–2007):
Low interest rates after the 2001 dot-com bust, combined with easy credit, fueled rapid house price increases (up ~124% from 1997–2006). Speculation drove demand, with many buying homes expecting perpetual price rises. When prices peaked and fell, homeowners (especially with adjustable-rate mortgages) faced negative equity, leading to defaults and foreclosures. -
Subprime Lending Boom:
Lenders issued high-risk “subprime” mortgages to borrowers with poor credit, low income, or no down payments (e.g., NINJA loans: No Income, No Job, No Assets). These often featured teaser rates that reset higher. Subprime originations rose from ~8% in 2001 to ~24% in 2006. Lenders profited by quickly selling loans, reducing incentives for careful underwriting. -
Securitization and Complex Financial Products:
Mortgages were bundled into mortgage-backed securities (MBS), collateralized debt obligations (CDOs), and sold globally. Credit default swaps (CDS) insured these, amplifying risk. High ratings from agencies (despite underlying risks) attracted investors seeking higher yields. When defaults rose, these securities plummeted in value. -
Deregulation and Lax Oversight:
Repeal of Glass-Steagall (1999) allowed commercial and investment banks to merge, increasing risk-taking. Limited regulation of shadow banking (e.g., hedge funds, derivatives) and “too big to fail” institutions encouraged excessive leverage (e.g., 30:1 ratios). The “Great Moderation” era bred complacency. -
High Leverage and Risk-Taking by Financial Institutions:
Banks and firms borrowed heavily to invest in housing-related assets. Global savings glut (from emerging markets) kept interest rates low, encouraging borrowing. -
Monetary Policy and Global Imbalances:
Fed’s low rates (1% in 2003–2004) contributed to the bubble. Some blame government policies promoting homeownership (e.g., via Fannie Mae/Freddie Mac), though private sector subprime lending was the main driver.
Key Timeline of Escalation:
- 2006–2007: House prices fall; subprime defaults rise; lenders like New Century bankrupt.
- August 2007: Credit markets freeze.
- March 2008: Bear Stearns rescued by JPMorgan (Fed-assisted).
- September 2008: Fannie/Freddie seized; Lehman bankrupt (triggering global panic); AIG bailed out.
- 2008–2009: Stock markets crash; recession deepens (U.S. GDP falls ~4.3%; unemployment peaks ~10%).
The crisis was avoidable per the Financial Crisis Inquiry Commission (2011), stemming from widespread failures in regulation, corporate governance, and risk management. It led to reforms like Dodd-Frank (2010) and global Basel III rules.
