See it on the Money & Finance map →How it works
As subprime defaults rose in 2007, losses spread through mortgage bonds held by banks and leveraged firms worldwide. Bear Stearns was sold in March 2008. In September, Fannie Mae and Freddie Mac were seized, Lehman failed, AIG was rescued and a money fund 'broke the buck'. Lending froze. The S&P 500 fell about 57% peak to trough, home prices about 27%, and unemployment reached 10%. Near-zero rates, QE, TARP and bank stress tests followed.
Why it matters
It reshaped finance: Dodd-Frank, higher bank capital, a far larger Fed balance sheet, and a decade of low rates that lifted property and stock prices.
Think of it like
Like a building with no firewalls: a fire in one corner, subprime, spread through hidden ducts of borrowing to the whole structure.
Facts, rules and data
The Financial Crisis Inquiry Commission report (2011), Fed and Treasury records, NBER recession dates (December 2007 to June 2009), and memoirs by Bernanke, Paulson and Geithner.
Debates and risks
Whether letting Lehman fail was a mistake, and whether the rescues saved the economy or entrenched too-big-to-fail banks, are still argued.

Connections (10)
▸Ben Bernanke, Fed chair 2006–2014 led the Fed through The 2008 global financial crisisFact, law or data
The connection
Bernanke used the Fed's emergency powers more broadly than any chair before him: he cut rates to near zero, lent to investment banks, money funds and the commercial paper market, helped rescue Bear Stearns and AIG, swapped dollars to foreign central banks, and launched quantitative easing to lower long-term rates.
When and why
Federal Reserve, Washington, August 2007 through 2009, working with Treasury Secretaries Henry Paulson and Timothy Geithner.
How we know
Fed lending data released in 2010 under Dodd-Frank, FOMC transcripts, and Bernanke's memoir 'The Courage to Act' (2015).
Debates and risks
Whether his actions prevented a second Depression, or bailed out the culprits and planted later asset bubbles, is still argued.
▸Glass–Steagall Act (1933) and its 1999 repeal is debated as a contributor to The 2008 global financial crisisExperts disagree
The connection
Critics argue the 1999 repeal let giant conglomerates like Citigroup mix insured deposits with trading and mortgage securities, raising risk. Defenders note the main failures, Bear Stearns, Lehman, AIG, Washington Mutual and Countrywide, were not combinations the old law barred, and that bank takeovers of Bear and Merrill Lynch helped contain the crisis.
When and why
Gramm–Leach–Bliley Act, signed by President Clinton in November 1999; crisis 2007–09.
How solid is the link?
Uncertain: the Financial Crisis Inquiry Commission (2011) blamed deregulation broadly but did not single out the repeal; economists remain split.
Debates and risks
Whether a new Glass–Steagall would make banks safer is still argued; bills from Senators Elizabeth Warren and John McCain (2013) and later versions never passed.
▸Dodd–Frank Act (2010) was the response to The 2008 global financial crisisFact, law or data
The connection
Congress matched fixes to failures it saw in 2008: no one watched system-wide risk (FSOC), no way to wind down a failing giant (orderly liquidation), opaque swaps (clearinghouses), abusive mortgages (the CFPB and ability-to-repay rules) and thin capital (stress tests and higher requirements).
When and why
Drafted 2009–10 by Senator Chris Dodd and Representative Barney Frank; signed by President Obama on July 21, 2010.
How we know
Its preamble names crisis-driven aims: end 'too big to fail' and bailouts, protect consumers. Treasury's June 2009 white paper, 'Financial Regulatory Reform: A New Foundation,' laid out the plan.
Debates and risks
Whether it addressed the real causes or mostly added cost is debated; the 2023 bank failures revived arguments over the 2018 rollback.
▸Shadow banking: credit outside the banking system suffered a run in The 2008 global financial crisisFact, law or data
The connection
Investment banks, mortgage vehicles and money funds financed long-term mortgage assets with short-term borrowing such as repo and commercial paper, without deposit insurance. When collateral values fell, lenders demanded more margin or stopped lending: a run without lines at the door. Bear Stearns and Lehman lost funding within days.
When and why
August 2007, when asset-backed commercial paper froze, through autumn 2008, centered on New York and London money markets.
How we know
Gary Gorton's research documented the 'run on repo'; FCIC and Fed data show commercial paper and repo shrinking sharply.
Debates and risks
Whether today's nonbank lenders, private credit funds and money funds could suffer a similar run, and who would backstop them, is debated.
▸The 2008 global financial crisis forced into conservatorship Fannie Mae, Freddie Mac and the FHFAFact, law or data
The connection
Fannie and Freddie backed about $5 trillion of mortgages with thin capital and also held risky subprime-linked securities. As home prices fell and losses mounted, investors feared they would fail. In September 2008 their new regulator, FHFA, took control as conservator, and Treasury promised capital, eventually about $191 billion, to keep them paying.
When and why
Washington, September 6–7, 2008; Treasury Secretary Henry Paulson and FHFA director James Lockhart, using powers from the July 2008 Housing and Economic Recovery Act.
How we know
FHFA conservatorship documents and Treasury's support agreements; the companies' filings show the draws and about $300 billion in dividends paid to Treasury by 2019.
Debates and risks
Whether they helped cause the crisis is debated: the official inquiry's majority said they followed rather than led Wall Street, while dissenters blamed government housing goals.
▸The 2008 global financial crisis triggered redemptions that exposed Bernie Madoff's Ponzi scheme (exposed 2008)Fact, law or data
The connection
A Ponzi scheme survives only while new money exceeds withdrawals. In late 2008, as markets crashed and funds needed cash, Madoff's investors and feeder funds asked for about $7 billion. With only a few hundred million dollars left in the account, he could not pay, and he confessed.
When and why
New York, December 2008: Madoff told his sons on December 10, and the FBI arrested him on December 11.
How we know
His plea statement and the trustee's account records show the cash shortfall and the redemption wave.
Debates and risks
Without the crisis, how long the scheme could have continued is unknown; inflows had been strong and the SEC had closed its 2006 inquiry.
▸Subprime mortgages and the housing bubble triggered The 2008 global financial crisisFact, law or data
The connection
When home prices fell and teaser rates reset, subprime defaults soared, and the bonds and CDOs built from those loans collapsed in value. Because banks and funds worldwide held them with borrowed money, the losses, and uncertainty over who held them, spread panic far beyond housing.
When and why
From early 2007: New Century Financial failed in April, two Bear Stearns hedge funds in July, and BNP Paribas froze three funds in August.
How we know
The FCIC report traces the chain; mortgage delinquency data and bank write-downs track it month by month.
Debates and risks
Subprime losses, perhaps a few hundred billion dollars, were small next to the crisis; how leverage and runs magnified them is the core debate.
▸Lehman Brothers bankruptcy (Sept 2008) was the climax of The 2008 global financial crisisFact, law or data
The connection
Lehman's bankruptcy was the moment a slow-moving crisis became a panic. A large money fund holding Lehman debt 'broke the buck', investors fled money funds, commercial paper froze and banks stopped lending to each other. Within weeks governments worldwide guaranteed their banks and Congress passed TARP.
When and why
New York, Monday, September 15, 2008; the Reserve Primary Fund broke the buck the next day.
How we know
Interbank lending spreads and money fund outflows jumped right after the filing, as the FCIC documented.
Debates and risks
Whether Lehman's failure caused the panic or was simply its most visible event, with AIG and others about to fail anyway, is debated.
▸Government-backed property loans: agency, HUD and SBA kept flowing when private lenders froze in The 2008 global financial crisisFact, law or data
The connection
In 2008–09, CMBS issuance collapsed and banks pulled back, but Fannie Mae, Freddie Mac and FHA kept funding apartment loans and became the dominant source of multifamily debt. Congress also raised SBA guarantees in 2009 and, in 2010, lifted the 7(a) loan limit from $2 million to $5 million.
When and why
2008–2010; Fannie and Freddie entered federal conservatorship in September 2008 yet kept lending; the 2009 Recovery Act and 2010 Small Business Jobs Act expanded SBA.
How we know
FHFA and MBA origination data, CMBS issuance tallies, and the texts of the 2009 and 2010 laws.
Debates and risks
Whether this crisis role was a lifeline or proof that Fannie and Freddie should stay large is part of the debate over ending their conservatorship.
▸CMBS delinquency waves (2009–12, 2020 and 2023–26) peaked at about 10% in 2012 after The 2008 global financial crisisFact, law or data
The connection
Loans written at peak 2005–07 values, with thin cushions and optimistic income projections, met the recession's falling rents and values. The delinquency rate rose from under 1% in 2007 to a record 10.34% in mid-2012, years after the crisis itself, partly because many loans failed only when they matured.
When and why
In US CMBS issued mainly in 2005–07, including a record of about $230 billion in 2007 alone.
How we know
Trepp's delinquency series and industry issuance data compiled by Commercial Mortgage Alert.
Debates and risks
How much of the 2010–12 rise came from loose underwriting rather than the recession, and why the peak lagged by three years.
