On September 15, 2008, Lehman Brothers Holdings Inc. filed for Chapter 11 bankruptcy protection with $639 billion in assets and $619 billion in debt — the largest bankruptcy in American history. Six months earlier, the Federal Reserve had orchestrated the emergency sale of Bear Stearns to JPMorgan Chase with $29 billion in government guarantees. Both firms faced liquidity crises driven by mortgage-backed securities exposure. Both posed systemic risk. One was rescued. One was allowed to collapse. The decision-makers — Treasury Secretary Henry Paulson, Fed Chairman Ben Bernanke, and New York Fed President Timothy Geithner — have offered conflicting explanations in the years since. This is what the documentary record shows about why Lehman fell.
On the afternoon of Friday, September 12, 2008, executives from the largest financial institutions in the United States received urgent phone calls from the New York Federal Reserve. They were summoned to an emergency meeting at the Fed's fortress-like building on Liberty Street in Lower Manhattan. The message was clear: Lehman Brothers Holdings Inc., the 158-year-old investment bank and the fourth-largest such institution in the country, was on the verge of collapse. They had the weekend to find a solution.
By Monday morning, Lehman Brothers had filed for Chapter 11 bankruptcy protection. The filing listed $639 billion in assets and $619 billion in debt, making it the largest bankruptcy in American history. Within 48 hours, credit markets froze globally. The Dow Jones Industrial Average fell 504 points on September 15 — the largest single-day drop since the September 11 attacks. The commercial paper market, which corporations use for short-term financing, essentially stopped functioning. The TED spread — a measure of credit stress that compares interbank lending rates to Treasury bill rates — spiked from 1.15 percentage points on September 12 to 4.65 percentage points by October 10, indicating near-total breakdown of trust in the financial system.
What made the Lehman bankruptcy particularly controversial was what had happened six months earlier. On the weekend of March 15-16, 2008, Bear Stearns — the fifth-largest investment bank — faced a liquidity crisis driven by mortgage-backed securities losses nearly identical to what would later afflict Lehman. Treasury Secretary Henry Paulson, Federal Reserve Chairman Ben Bernanke, and New York Fed President Timothy Geithner orchestrated an emergency sale of Bear Stearns to JPMorgan Chase. The Fed provided $29 billion in guarantees against Bear's riskiest assets — the first time since the Great Depression the central bank had intervened to prevent an investment bank failure.
The Bear Stearns rescue established what market participants believed was a new precedent: systemically important financial institutions would not be allowed to fail. When Lehman faced similar pressures in September, Wall Street assumed a similar arrangement would be made. That assumption proved catastrophically wrong.
In the years since September 15, 2008, the three principal decision-makers — Paulson, Bernanke, and Geithner — have offered explanations for why Lehman was allowed to fail while Bear Stearns was rescued and AIG was bailed out just 24 hours later. Their explanations are not fully consistent with each other or with the documentary record.
Paulson has emphasized lack of legal authority. In testimony before the Financial Crisis Inquiry Commission in May 2010, he stated: "We had no authority to put money into Lehman Brothers... we did not have the powers." Paulson argued that unlike the Federal Reserve, which can provide emergency loans, the Treasury cannot inject capital into private firms without Congressional authorization. He maintained that no buyer was willing to acquire Lehman without government loss guarantees similar to those provided for Bear Stearns, and he refused to provide them.
"The only way we could have saved Lehman would have been by breaking the law."
Ben Bernanke — Testimony to Financial Crisis Inquiry Commission, September 2, 2010Bernanke has focused on the collateral requirement. Section 13(3) of the Federal Reserve Act allows the Fed to make emergency loans to non-bank entities during "unusual and exigent circumstances," but such loans must be "secured to the satisfaction of the Federal Reserve Bank." In testimony to the FCIC in September 2010, Bernanke stated flatly: "The only way we could have saved Lehman would have been by breaking the law." He explained that Fed staff assessed Lehman's assets and determined they were insufficient and too impaired to secure a loan of adequate size. The firm's commercial real estate holdings and mortgage-backed securities had declined sharply in value, and there was no reliable way to value them quickly.
Geithner has emphasized the absence of a buyer. In his 2014 memoir "Stress Test," Geithner wrote that he, Paulson, and Bernanke explored every possible option but that Lehman's deteriorated condition combined with the lack of a willing acquirer made rescue impossible. He has stated that once Barclays withdrew from negotiations late Sunday night — after the UK Financial Services Authority refused to approve the deal without a 60-day shareholder vote — there was no viable path forward.
The Barclays negotiations represented the closest Lehman came to survival. Barclays CEO John Varley and President Bob Diamond had been interested in acquiring Lehman's North American broker-dealer operations for months. Throughout the September 13-14 weekend, Barclays executives negotiated with Lehman and US officials at the New York Fed building.
By Sunday afternoon, the parties had reached a preliminary agreement. Barclays would acquire Lehman's core broker-dealer for approximately $3-4 billion and assume certain liabilities. There was one critical condition: Barclays needed to guarantee Lehman's trading obligations immediately to prevent chaos when markets opened Monday morning. Lehman was counterparty to thousands of derivatives contracts, repurchase agreements, and other trades that would need to be honored.
The problem was UK law. The Financial Services Authority informed Barclays that any acquisition would require shareholder approval under the UK Companies Act — a process that could not be completed for at least 60 days. More critically, the FSA refused to allow Barclays to provide the immediate guarantees US officials insisted were necessary. FSA Chairman Callum McCarthy later testified that the regulator was concerned about Barclays taking on unknown liabilities from Lehman given the opacity of Lehman's positions and rapidly deteriorating market conditions.
At approximately 9:00 p.m. Sunday evening, Barclays withdrew. Treasury Secretary Paulson later wrote: "I will never forget how frustrated I felt" when informed of the UK regulator's decision. The irony is that Barclays purchased Lehman's North American broker-dealer operations out of bankruptcy just two days later, on September 17, for $1.75 billion — a fraction of the weekend's negotiated price.
The other serious potential acquirer was Bank of America, led by CEO Kenneth Lewis. BofA had conducted extensive due diligence on Lehman's assets throughout the summer of 2008. The bank's analysis identified approximately $65-67 billion in Lehman holdings — primarily commercial real estate loans and mortgage-backed securities — that BofA considered too risky to acquire without government guarantees.
On Saturday, September 13, Lewis requested that the Federal Reserve or Treasury provide loss protection similar to the $29 billion in guarantees JPMorgan received for Bear Stearns. Paulson refused. In his memoir "On the Brink," Paulson explained that the political backlash from the Bear Stearns rescue — accusations of rewarding reckless behavior and creating moral hazard — convinced him that drawing a line was necessary. "I had come to the conclusion," Paulson wrote, "that we needed to demonstrate we would not rescue every failing institution."
On Sunday morning, Bank of America informed officials it was withdrawing from Lehman negotiations. Instead, BofA would pursue Merrill Lynch, which had approached Lewis seeking a merger as it faced its own mounting losses. Merrill had stronger capital ratios than Lehman and less concentrated exposure to commercial real estate, though it too held massive mortgage securities losses. Bank of America announced the Merrill Lynch acquisition for $50 billion on Monday, September 15 — the same day Lehman filed for bankruptcy.
The most damaging evidence against officials' explanations came on Tuesday, September 16 — just 24 hours after Lehman's bankruptcy. American International Group, the world's largest insurance company, faced collapse as mortgage securities losses triggered massive collateral calls on its credit default swap positions. AIG needed approximately $85 billion immediately to avoid bankruptcy.
That evening, the Federal Reserve announced it would provide AIG with an $85 billion emergency loan under Section 13(3) of the Federal Reserve Act — the same legal authority Bernanke testified could not be used to save Lehman because of insufficient collateral. In exchange, the government took a 79.9% equity stake in AIG.
The apparent contradiction was stark. Officials stated on Sunday that they lacked legal authority to rescue Lehman. On Tuesday, they used that exact authority to rescue AIG with a loan three times larger than what would have been needed to stabilize Lehman.
Officials have defended the inconsistency on two grounds. First, they argue that AIG, unlike Lehman, had sufficient collateral to secure the Fed loan — primarily its insurance subsidiaries' investment portfolios and future premium income. Second, they contend that AIG's failure would have caused even greater systemic damage than Lehman's because AIG was a counterparty to virtually every major financial institution globally through its credit default swap positions.
Critics, including bankruptcy examiner Anton Valukas, have questioned both explanations. Valukas's 2,200-page report notes that Fed officials did not complete a detailed collateral analysis for AIG before approving the loan — they moved far more quickly than the collateral assessment supposedly done for Lehman. Regarding systemic importance, Valukas points out that Lehman was also deeply interconnected to the global financial system, and officials had six months after Bear Stearns to prepare for a potential Lehman failure but did not require counterparties to reduce exposures or build adequate buffers.
One reason officials may have misjudged Lehman's condition is that the firm had systematically misrepresented its financial position through an accounting technique called Repo 105. The bankruptcy examiner's investigation revealed that Lehman had used repurchase agreements — short-term collateralized loans — in a way that temporarily removed approximately $50 billion from its balance sheet at quarter-end.
In a standard repurchase agreement, or repo, a firm sells securities with an agreement to repurchase them at a specified future date. These transactions are normally accounted for as financings — the securities remain on the balance sheet as assets, and the cash received is recorded as a liability. However, if certain conditions are met, Generally Accepted Accounting Principles allow repos to be treated as sales, removing both the securities and the obligation from the balance sheet.
Lehman exploited this provision through what it internally called Repo 105 transactions. By overcollateralizing the transactions — providing securities worth 105% of the cash received — Lehman's lawyers argued the firm had surrendered effective control, making sale treatment appropriate. Lehman executed these transactions just before quarter-end reporting dates, temporarily moving $50 billion off its books to make its leverage ratio appear lower than it actually was. After the quarterly reports were filed, Lehman repurchased the securities and the assets returned to the balance sheet.
"Lehman's use of Repo 105 was intended solely for one purpose: reduction of the balance sheet."
Anton Valukas — Bankruptcy Examiner's Report, March 11, 2010Valukas concluded that Lehman's characterization of Repo 105 as sales was "accounting gimmickry" that did not meet the GAAP requirement that the transferor surrender effective control. More troubling, he found that Lehman's senior executives — including CEO Richard Fuld and CFO Erin Callan — were aware of the practice and understood it was being used to manage the balance sheet.
Ernst & Young, Lehman's auditor, signed off on financial statements that incorporated Repo 105 accounting. The firm reviewed Lehman's legal opinion from UK law firm Linklaters supporting the treatment and concluded it was acceptable. Valukas's report stated that Ernst & Young's acceptance of Repo 105 "was professionally unreasonable" and that "there are colorable claims against Ernst & Young for negligence."
The Financial Crisis Inquiry Commission's 2011 report examined the legal authority question in detail. The Commission concluded: "In the view of many, if not most, leading experts in bankruptcy and financial regulation, if government stabilization of Lehman was indeed infeasible, it was because of the constraints of policy, not law."
The Commission noted several problems with officials' legal explanations. First, regarding Treasury's claimed lack of authority to inject capital: Paulson requested and Congress passed the $700 billion Troubled Asset Relief Program just two weeks after Lehman's bankruptcy, on October 3, 2008. TARP explicitly authorized Treasury to purchase equity in financial institutions. The legislation was drafted and introduced in the days immediately following Lehman's collapse, suggesting such authority could have been sought earlier.
Second, regarding the Fed's collateral requirements: The Federal Reserve has extremely broad discretion in determining what collateral is acceptable "to the satisfaction of the Federal Reserve Bank." The statute does not specify asset quality standards or valuation methods. In the AIG rescue 24 hours after Lehman, the Fed accepted insurance subsidiaries' investment portfolios as collateral without completing the detailed valuation that officials claimed was impossible for Lehman. In subsequent rescues, including Citigroup and Bank of America, the Fed demonstrated considerable flexibility in assessing collateral adequacy.
Third, the Commission found internal Federal Reserve documents showing that Fed staff did not complete a comprehensive assessment of what assets Lehman held or what their value might be under various scenarios. An email from a senior Fed official on September 13 stated: "It would be extraordinarily difficult to determine what to lend against at Lehman." This suggests the decision was based on practical difficulty rather than legal impossibility.
Legal scholars who have examined the question largely agree with the Commission. Columbia Law School professor John Coffee testified: "The Fed had ample legal authority to rescue Lehman. The decision not to was one of policy." Harvard Law professor Hal Scott concluded: "Bernanke's claim that the Fed lacked authority is incorrect as a matter of law."
If legal authority existed, why did officials choose not to use it? The answer appears to be a policy judgment about moral hazard — the concern that rescuing firms encourages excessive risk-taking by creating expectations of bailouts.
In Congressional testimony and subsequent memoirs, all three principal decision-makers emphasized that the Bear Stearns rescue had created political and economic problems. Paulson wrote: "The reaction to Bear Stearns had been fierce. Critics across the political spectrum had excoriated us for bailing out Wall Street." Senator Jim Bunning, a Republican from Kentucky, stated in March 2008: "The Fed has put the taxpayers on the hook for billions of dollars to bail out an investment bank that made reckless bets on risky securities."
Geithner has acknowledged that the decision to let Lehman fail was influenced by concern about creating expectations: "We worried that another rescue would make the problem worse by convincing markets that we would save everyone." Paulson similarly wrote: "I had concluded we needed to demonstrate that not every institution would be saved."
The problem with this explanation is timing. If establishing a credible no-bailout policy was the goal, allowing Lehman to fail proved immediately counterproductive. Within 24 hours, officials rescued AIG. Within two weeks, they requested Congressional authorization for $700 billion in TARP funds that were used to inject capital into hundreds of financial institutions. Far from establishing that some firms would be allowed to fail, the Lehman bankruptcy and subsequent crisis response convinced markets that every institution except Lehman would be saved — exactly the opposite of officials' stated intent.
Perhaps the most damaging evidence against the decision to let Lehman fail is what officials did not do in the six months between Bear Stearns and Lehman. After rescuing Bear in March 2008, policymakers had extensive warning that other investment banks faced similar pressures. Lehman's stock price declined 73% between March and early September. The firm reported a $2.8 billion loss in the second quarter and a $3.9 billion loss in the third quarter. Short sellers publicly targeted Lehman, and the firm's credit default swap spreads — market-based measures of default probability — widened dramatically.
Despite these warning signs, officials did not require Lehman's counterparties to reduce exposures, did not mandate that derivatives contracts include adequate collateral buffers, and did not develop resolution procedures for handling a major broker-dealer bankruptcy. Geithner later acknowledged: "We should have done more to prepare the system for the failure of a major institution."
The Financial Crisis Inquiry Commission concluded: "The government's response to the failure of Lehman Brothers was ad hoc and inadequate. Senior government officials had months to prepare for Lehman's potential collapse, but they failed to act."
Internal Federal Reserve emails obtained by the Commission show that some Fed staff raised concerns about inadequate preparation. One email from a New York Fed economist dated August 2008 stated: "If Lehman goes down, the consequences will be far worse than Bear. We need contingency plans." No comprehensive contingency planning occurred.
In October 2008, the House Committee on Oversight and Government Reform held hearings where Lehman CEO Richard Fuld testified. Representative Henry Waxman confronted Fuld with evidence of his compensation: approximately $484 million between 2000 and 2008. Waxman asked: "Is that fair?" Fuld responded: "I believe compensation should be commensurate with success... I take full responsibility."
No senior Lehman executive was criminally prosecuted. The Department of Justice and Securities and Exchange Commission conducted investigations but concluded that while Lehman executives made catastrophically bad business judgments, they did not commit prosecutable crimes. The use of Repo 105 accounting, while misleading, was not clearly illegal given that Ernst & Young had approved it and UK legal opinions supported it.
Civil lawsuits were more successful. Lehman shareholders filed class action suits that were settled for $612 million, paid primarily by insurance companies. New York Attorney General Andrew Cuomo sued Ernst & Young for $150 million in December 2010, alleging professional negligence. The case settled in 2015 with Ernst & Young paying $10 million — an amount critics called woefully inadequate given the magnitude of losses involved.
The Dodd-Frank Wall Street Reform and Consumer Protection Act, passed in July 2010, was Congress's primary legislative response. The law created an orderly liquidation authority allowing the Federal Deposit Insurance Corporation to take over and wind down failing systemically important financial institutions. This authority — which officials claimed they lacked in September 2008 — can be invoked without Congressional approval and does not require a willing private-sector buyer. The legislation also established the Financial Stability Oversight Council to monitor systemic risks and subjected large investment banks to Federal Reserve supervision.
Sixteen years later, the question remains: was Lehman's bankruptcy inevitable, or was it a policy choice? The documentary evidence suggests it was a choice — one made under extreme time pressure, with imperfect information, and with competing considerations about legal authority, political constraints, and moral hazard.
The tragedy is that the decision appears to have been wrong on every dimension officials claimed to care about. If the goal was to establish a credible no-bailout policy, it failed — AIG was rescued the next day and hundreds of institutions received TARP funds within weeks. If the goal was to avoid legal constraints, the evidence shows those constraints were not absolute. If the goal was to minimize systemic damage, the Lehman bankruptcy triggered the worst financial crisis since the Great Depression and a global recession that cost tens of millions of jobs.
What the Lehman collapse definitively proved is that the United States had no functional resolution regime for handling the failure of a major financial institution. The bankruptcy system designed for industrial companies was catastrophically inadequate for a interconnected broker-dealer with thousands of derivatives positions and operations in dozens of countries. It took six years for Lehman's bankruptcy to be substantially resolved, at enormous cost to creditors, counterparties, and the broader economy.
The people who made the decision — Paulson, Bernanke, and Geithner — have never fully agreed on why Lehman was allowed to fail while other institutions were rescued. Their conflicting explanations, combined with the documentary evidence of legal authority that went unused and preparation that never occurred, suggest that September 15, 2008 represents not inevitable market forces but human judgment under crisis — judgment that proved disastrously wrong.
