The Lehman Brothers Collapse: The Bankruptcy That Shook the World
What Was Lehman Brothers?
Founded in 1850 as a cotton trading business in Alabama, Lehman Brothers grew into the fourth-largest US investment bank. By 2007, it had $691 billion in assets, 25,000 employees, and was a major player in fixed income, equity trading, and investment banking.
But Lehman had made an enormous bet on real estate. The firm had aggressively expanded into mortgage-backed securities and commercial real estate, using extreme leverage — roughly 31:1 by some measures — to amplify returns.
How Lehman Failed
Massive mortgage exposure. Lehman held approximately $85 billion in mortgage-related assets — more than four times its equity. When housing prices declined and mortgage defaults surged, these assets lost value rapidly.
Repo 105 accounting. Lehman used a controversial technique called “Repo 105” to temporarily move $50 billion in assets off its balance sheet at the end of each quarter, making its leverage appear lower than it actually was. While technically legal, this practice obscured the firm’s true financial condition from investors and regulators.
Confidence collapse. After Bear Stearns was rescued in March 2008, attention turned to Lehman as the next most vulnerable bank. The firm’s stock fell from $65 in January 2008 to $4 by September as counterparties and clients pulled away.
No rescue. Unlike Bear Stearns (sold to JPMorgan with a Fed guarantee) and AIG (bailed out the following day), Lehman received no government support. Treasury Secretary Hank Paulson and Fed Chairman Ben Bernanke concluded that Lehman lacked sufficient collateral for an emergency loan and that moral hazard concerns required drawing a line.

Why Lehman’s Failure Was So Devastating
Counterparty contagion. Lehman was a counterparty to thousands of derivatives trades with every major bank globally. Its bankruptcy meant that counterparties couldn’t collect on positions, creating uncertainty about who was exposed and by how much. Banks stopped lending to each other because nobody knew who was solvent.
Money market fund shock. The Reserve Primary Fund, a money market fund holding $785 million in Lehman debt, “broke the buck” — its share price fell below $1.00. This triggered a run on money market funds industry-wide, with $300 billion withdrawn in a week.
Credit market freeze. Commercial paper markets — where companies borrow for short-term needs — seized up completely. Even healthy companies couldn’t finance day-to-day operations. The liquidity crisis spread from Wall Street to Main Street.
Lehman Brothers vs. Bear Stearns
| Factor | Lehman Brothers | Bear Stearns |
|---|---|---|
| Assets at failure | $639 billion | $395 billion |
| Employees | 25,000 | 13,500 |
| Outcome | Bankruptcy (no rescue) | Sold to JPMorgan ($10/share + Fed guarantee) |
| Government role | None — allowed to fail | Fed provided $30B asset guarantee |
| Systemic impact | Catastrophic — triggered global panic | Severe but contained |
| Key lesson | Inconsistent bailout policy creates worse panic | Speed matters — early intervention prevents cascade |
The Debate: Should Lehman Have Been Saved?
This remains the most debated question of the 2008 crisis. Two perspectives dominate:
The case for letting Lehman fail: Bailing out every failing institution creates moral hazard — firms take excessive risks knowing taxpayers will absorb losses. Drawing a line at Lehman sent a message that reckless behavior has consequences.
The case against: The chaos that followed Lehman’s bankruptcy was vastly more expensive than a rescue would have been. The government bailed out AIG the very next day for $85 billion, and the subsequent TARP program cost $700 billion. Letting Lehman fail to “make a point” while rescuing everyone else made the total cost far higher.
Key Takeaways
- Lehman Brothers’ September 15, 2008 bankruptcy ($639 billion in assets) was the largest in US history and the pivotal moment of the 2008 financial crisis.
- The firm collapsed due to massive mortgage exposure, extreme leverage (~31:1), and accounting practices (Repo 105) that obscured its true financial condition.
- Unlike Bear Stearns or AIG, Lehman received no government rescue — a decision that remains one of the most debated in financial history.
- The failure triggered counterparty panic, money market fund runs, and a complete freeze in credit markets that nearly collapsed the global financial system.
- Lehman’s collapse demonstrated that inconsistent bailout policies can create worse outcomes than either consistent rescue or consistent non-intervention.
Frequently Asked Questions
Why did Lehman Brothers collapse?
Lehman collapsed due to massive exposure to mortgage-backed securities (roughly $85 billion), extreme leverage (31:1), and a loss of confidence that caused counterparties and clients to pull away. When no buyer materialized and the government declined to intervene, the firm filed for bankruptcy on September 15, 2008.
Why wasn’t Lehman Brothers bailed out?
The official explanation is that Lehman lacked sufficient collateral for a Federal Reserve emergency loan, and no private buyer was willing to proceed without government guarantees. Some analysts believe the decision was also influenced by a desire to demonstrate that moral hazard had limits, though the government reversed course and bailed out AIG the very next day.
How much was Lehman Brothers worth before it collapsed?
Lehman’s stock peaked at roughly $86 per share in early 2007, giving it a market capitalization of approximately $60 billion. By the time it filed for bankruptcy, the stock was trading under $0.50. The firm had $639 billion in assets and $619 billion in debt.
What happened to Lehman Brothers employees?
Most of Lehman’s 25,000 employees lost their jobs. Barclays purchased Lehman’s North American operations (and took on about 10,000 employees), while Nomura acquired the Asian and European businesses. Many employees also held significant amounts of Lehman stock in their compensation packages, which became worthless.
What was the impact of Lehman Brothers’ collapse?
Lehman’s failure triggered a cascading global panic: the Reserve Primary Fund “broke the buck,” credit markets froze, stock markets crashed worldwide, and the Fed and Treasury had to implement emergency measures (AIG bailout, TARP, money market guarantees) to prevent a complete financial system collapse. It turned the 2008 financial crisis from severe to catastrophic.
