Date:
2007 - 2008
financial crisis of 2007â08
, severe contraction of liquidity in global financial markets that originated in the
United States
as a result of the collapse of the U.S.
housing market
. It threatened to destroy the international financial system; caused the failure (or near-failure) of several major
investment
and
commercial banks
,
mortgage
lenders,
insurance
companies, and
savings and loan associations
; and precipitated the
Great Recession
(2007â09), the worst economic downturn since the
Great Depression
(1929â
c.
1939).
Causes of the crisis
Although the exact causes of the financial crisis are a matter of dispute among economists, there is general agreement regarding the factors that played a role (experts disagree about their relative importance).
First, the
Federal Reserve
(Fed), the
central bank
of the United States, having anticipated a mild
recession
that began in 2001, reduced the
federal funds rate
(the
interest
rate that
banks
charge each other for overnight loans of federal fundsâi.e., balances held at a Federal Reserve bank) 11 times between May 2000 and December 2001, from 6.5 percent to 1.75 percent. That significant decrease enabled banks to extend
consumer credit
at a lower prime rate (the
interest rate
that banks charge to their âprime,â or low-risk, customers, generally three percentage points above the federal funds rate) and encouraged them to lend even to âsubprime,â or high-risk, customers, though at higher interest rates (
see
subprime lending
). Consumers took advantage of the cheap credit to purchase durable goods such as appliances, automobiles, and especially houses. The result was the creation in the late 1990s of a âhousing bubbleâ (a rapid increase in home prices to levels well beyond their fundamental, or intrinsic, value, driven by excessive speculation).
Second, owing to changes in banking laws beginning in the 1980s, banks were able to offer to subprime customers
mortgage
loans that were structured with balloon payments (unusually large payments that are due at or near the end of a loan period) or adjustable interest rates (rates that remain fixed at relatively low levels for an initial period and float, generally with the federal funds rate, thereafter). As long as home prices continued to increase, subprime borrowers could protect themselves against high mortgage payments by refinancing, borrowing against the increased value of their homes, or selling their homes at a profit and paying off their mortgages. In the case of default, banks could repossess the property and sell it for more than the amount of the original loan. Subprime lending thus represented a lucrative investment for many banks. Accordingly, many banks aggressively marketed subprime loans to customers with poor credit or few assets, knowing that those borrowers could not afford to repay the loans and often misleading them about the risks involved. As a result, the share of
subprime mortgages
among all home loans increased from about 2.5 percent to nearly 15 percent per year from the late 1990s to 2004â07.
Third, contributing to the growth of subprime lending was the widespread practice of
securitization
, whereby banks bundled together hundreds or even thousands of subprime mortgages and other, less-risky forms of consumer
debt
and sold them (or pieces of them) in capital markets as
securities
(bonds) to other banks and investors, including hedge funds and pension funds. Bonds consisting primarily of mortgages became known as
mortgage-backed securities
, or MBSs, which entitled their purchasers to a share of the interest and principal payments on the underlying loans. Selling subprime mortgages as MBSs was considered a good way for banks to increase their liquidity and reduce their exposure to risky loans, while purchasing MBSs was viewed as a good way for banks and investors to diversify their portfolios and earn money. As home prices continued their meteoric rise through the early 2000s, MBSs became widely popular, and their prices in capital markets increased accordingly.

Fourth, in 1999 the Depression-era Glass-Steagall Act (1933) was partially repealed, allowing banks, securities firms, and insurance companies to enter each otherâs markets and to merge, resulting in the formation of banks that were âtoo big to failâ (i.e., so big that their failure would threaten to undermine the entire financial system). In addition, in 2004 the
Securities and Exchange Commission
(SEC) weakened the net-capital requirement (the ratio of capital, or assets, to debt, or liabilities, that banks are required to maintain as a safeguard against insolvency), which encouraged banks to invest even more money into MBSs. Although the SECâs decision resulted in enormous profits for banks, it also exposed their portfolios to significant risk, because the asset value of MBSs was implicitly premised on the continuation of the housing bubble.
Fifth, and finally, the long period of global economic stability and growth that immediately preceded the crisis, beginning in the mid- to late 1980s and since known as the âGreat Moderation,â had convinced many U.S. banking executives, government officials, and economists that extreme economic volatility was a thing of the past. That confident attitudeâtogether with an ideological climate emphasizing deregulation and the ability of financial firms to police themselvesâled almost all of them to ignore or discount clear signs of an impending crisis and, in the case of bankers, to continue reckless lending, borrowing, and securitization practices.
Key events of the crisis
Beginning in 2004 a series of developments portended the coming crisis, though very few economists anticipated its vast scale. Over a two-year period (June 2004 to June 2006) the Fed raised the
federal funds rate
from 1.25 to 5.25 percent, inevitably resulting in more defaults from subprime borrowers holding
adjustable-rate mortgages
(ARMs). Partly because of the rate increase, but also because the housing market had reached a saturation point, home sales, and thus home prices, began to fall in 2005. Many
subprime mortgage
holders were unable to rescue themselves by borrowing, refinancing, or selling their homes, because there were fewer buyers and because many mortgage holders now owed more on their loans than their homes were worth (they were âunderwaterâ)âan increasingly common phenomenon as the crisis developed. As more and more subprime borrowers defaulted and as home prices continued to slide, MBSs based on subprime mortgages lost value, with dire consequences for the portfolios of many banks and investment firms. Indeed, because MBSs generated from the U.S. housing market had also been bought and sold in other countries (notably in western Europe), many of which had experienced their own housing bubbles, it quickly became apparent that the trouble in the
United States
would have global implications, though most experts insisted that the problems were not as serious as they appeared and that damage to financial markets could be contained.
By 2007 the steep decline in the value of MBSs had caused major losses at many banks,
hedge funds
, and mortgage lenders and forced even some large and prominent firms to liquidate hedge funds that were invested in MBSs, to appeal to the government for loans, to seek mergers with healthier companies, or to declare
bankruptcy
. Even firms that were not immediately threatened sustained losses in the billions of dollars, as the MBSs in which they had invested so heavily were now downgraded by credit-rating agencies, becoming âtoxicâ (essentially worthless) assets. (Such agencies were later accused of a severe conflict of interest, because their services were paid for by the same banks whose debt securities they rated. That financial relationship initially created an incentive for agencies to assign deceptively high ratings to some MBSs, according to critics.) In April 2007 New Century Financial Corp., one of the largest subprime lenders, filed for bankruptcy, and soon afterward many other subprime lenders ceased operations. Because they could no longer fund subprime loans through the sale of MBSs, banks stopped lending to subprime customers, causing home sales and home prices to decline further, which discouraged home buying even among consumers with prime credit ratings, further depressing sales and prices. In August, Franceâs largest bank,
BNP Paribas
, announced billions of dollars in losses, and another large U.S. firm, American Home Mortgage Investment Corp., declared bankruptcy.
In part because it was difficult to determine the extent of subprime debt in any given
MBS
(because MBSs were typically sold in pieces, mixed with other debt, and resold in capital markets as new securities in a process that could continue indefinitely), it was also difficult to assess the strength of bank portfolios containing MBSs as assets, even for the bank that owned them. Consequently, banks began to doubt one anotherâs solvency, which led to a freeze in the federal funds market with potentially disastrous consequences. In early August the Fed began purchasing federal funds (in the form of government securities) to provide banks with more liquidity and thereby reduce the federal funds rate, which had briefly exceeded the Fedâs target of 5.25 percent. Central banks in other parts of the worldânotably in the
European Union
, Australia, Canada, and Japanâconducted similar
open-market operations
. The Fedâs intervention, however, ultimately failed to stabilize the U.S.
financial market
, forcing the Fed to directly reduce the federal funds rate three times between September and December, to 4.25 percent. During the same period, the fifth largest mortgage lender in the United Kingdom, Northern Rock, ran out of liquid assets and appealed to the
Bank of England
for a loan. News of the bailout created panic among depositors and resulted in the first bank runs in the United Kingdom in 150 years. Northern Rock was nationalized by the British government in February 2008.
The crisis in the United States deepened in January 2008 as
Bank of America
agreed to purchase Countrywide Financial, once the countryâs leading mortgage lender, for $4 billion in stock, a fraction of the companyâs former value. In March the prestigious
Wall Street
investment firm
Bear Stearns
, having exhausted its liquid assets, was purchased by
JPMorgan Chase
, which itself had sustained billions of dollars in losses. Fearing that Bear Stearnsâs bankruptcy would threaten other major banks from which it had borrowed, the Fed facilitated the sale by assuming $30 billion of the firmâs high-risk assets. Meanwhile, the Fed initiated another round of reductions in the federal funds rate, from 4.25 percent in early January to only 2 percent in April (the rate was reduced again later in the year, to 1 percent by the end of October and to effectively 0 percent in December). Although the rate cuts and other interventions during the first half of the year had some stabilizing effect, they did not end the crisis; indeed, the worst was yet to come.
By the summer of 2008
Fannie Mae
(the Federal National Mortgage Association) and
Freddie Mac
(the Federal Home Loan Mortgage Corporation), the federally chartered corporations that dominated the secondary mortgage market (the market for buying and selling mortgage loans) were in serious trouble. Both institutions had been established to provide liquidity to mortgage lenders by buying mortgage loans and either holding them or selling themâwith a guarantee of principal and interest paymentsâto other banks and investors. Both were authorized to sell mortgage loans as MBSs. As the share of subprime mortgages among all home loans began to increase in the early 2000s (partly because of policy changes designed to boost home ownership among low-income and minority groups), the portfolios of Fannie Mae and Freddie Mac became more risky, as their liabilities would be huge should large numbers of mortgage holders default on their loans. Once MBSs created from subprime loans lost value and eventually became toxic, Fannie Mae and Freddie Mac suffered enormous losses and faced bankruptcy. To prevent their collapse, the
U.S. Treasury Department
nationalized both corporations in September, replacing their directors and pledging to cover their debts, which then amounted to some $1.6 trillion.
Later that month the 168-year-old
investment bank
Lehman Brothers, with $639 billion in assets, filed the largest bankruptcy in U.S. history
. Its failure created lasting turmoil in financial markets worldwide, severely weakened the portfolios of the banks that had loaned it money, and fostered new distrust among banks, leading them to further reduce interbank lending. Although Lehman had tried to find partners or buyers and had hoped for government assistance to facilitate a deal, the Treasury Department refused to intervene, citing âmoral hazardâ (in this case, the risk that rescuing Lehman would encourage future reckless behaviour by other banks, which would assume that they could rely on government assistance as a last resort). Only one day later, however, the Fed agreed to loan American International Group (AIG), the countryâs largest insurance company, $85 billion to cover losses related to its sale of
credit default swaps
(CDSs), a financial contract that protects holders of various debt instruments, including MBSs, in the event of default on the underlying loans. Unlike Lehman, AIG was deemed âtoo big to fail,â because its collapse would likely cause the failure of many banks that had bought CDSs to insure their purchases of MBSs, which were now worthless. Less than two weeks after Lehmanâs demise, Washington Mutual, the countryâs largest savings and loan, was seized by federal regulators and sold the next day to
JPMorgan Chase
.
By this time there was general agreement among economists and Treasury Department officials that a more forceful government response was necessary to prevent a complete breakdown of the financial system and lasting damage to the U.S. economy. In September the
George W. Bush
administration proposed legislation, the
Emergency Economic Stabilization Act
(EESA), which would establish a
Troubled Asset Relief Program
(TARP), under which the Secretary of the Treasury,
Henry Paulson
, would be authorized to purchase from U.S. banks up to $700 billion in MBSs and other âtroubled assets.â After the legislation was initially rejected by the
House of Representatives
, a majority of whose members perceived it as an unfair bailout of Wall Street banks, it was amended and passed in the
Senate
. As the countryâs financial system continued to deteriorate, several representatives changed their minds, and the House passed the legislation on October 3, 2008; President Bush signed it the same day.
It soon became apparent, however, that the governmentâs purchase of MBSs would not provide sufficient liquidity in time to avert the failure of several more banks. Paulson was therefore authorized to use up to $250 billion in TARP funds to purchase preferred stock in troubled financial institutions, making the federal government a part-owner of more than 200 banks by the end of the year. The Fed thereafter undertook a variety of extraordinary quantitative-easing (QE) measures, under several overlapping but differently named programs, which were designed to use money created by the Fed to inject liquidity into capital markets and thereby to stimulate
economic growth
. Similar interventions were undertaken by central banks in other countries. The Fedâs measures included the purchase of long-term U.S. Treasury bonds and MBSs for prime mortgage loans, loan facilities for holders of high-rated securities, and the purchase of MBSs and other debt held by Fannie Mae and Freddie Mac. By the time the QE programs were officially ended in 2014, the Fed had by such means pumped more than $4 trillion into the U.S. economy. Despite warnings from some economists that the creation of trillions of dollars of new money would lead to hyperinflation, the U.S.
inflation
rate remained below the Fedâs target rate of 2 percent through the end of 2014.
There is now general agreement that the measures taken by the Fed to protect the U.S. financial system and to spur economic growth helped to prevent a global economic catastrophe. In the United States, recovery from the worst effects of the
Great Recession
was also aided by the
American Recovery and Reinvestment Act
, a $787 billion stimulus and relief program proposed by the
Barack Obama
administration and adopted by
Congress
in February 2009. By the middle of that year, financial markets had begun to revive, and the economy had begun to grow after nearly two years of deep
recession
. In 2010 Congress adopted the
Wall Street Reform and Consumer Protection Act
(the
Dodd-Frank Act
), which instituted banking regulations to prevent another financial crisis and created a
Consumer Financial Protection Bureau
, which was charged with regulating, among other things, subprime mortgage loans and other forms of
consumer credit
. After 2017, however, many provisions of the Dodd-Frank Act were rolled back or effectively neutered by a
Republican
-controlled Congress and the
Donald J. Trump
administration, both of which were hostile to the lawâs approach. |

The result was the creation in the late 1990s of a âhousing bubbleâ (a rapid increase in home prices to levels well beyond their fundamental, or intrinsic, value, driven by excessive speculation).
Second, owing to changes in banking laws beginning in the 1980s, banks were able to offer to subprime customers [mortgage](https://www.britannica.com/money/mortgage) loans that were structured with balloon payments (unusually large payments that are due at or near the end of a loan period) or adjustable interest rates (rates that remain fixed at relatively low levels for an initial period and float, generally with the federal funds rate, thereafter).

Fourth, in 1999 the Depression-era Glass-Steagall Act (1933) was partially repealed, allowing banks, securities firms, and insurance companies to enter each otherâs markets and to merge, resulting in the formation of banks that were âtoo big to failâ (i.e., so big that their failure would threaten to undermine the entire financial system). In addition, in 2004 the [Securities and Exchange Commission](https://www.britannica.com/money/Securities-and-Exchange-Commission) (SEC) weakened the net-capital requirement (the ratio of capital, or assets, to debt, or liabilities, that banks are required to maintain as a safeguard against insolvency), which encouraged banks to invest even more money into MBSs. Although the SECâs decision resulted in enormous profits for banks, it also exposed their portfolios to significant risk, because the asset value of MBSs was implicitly premised on the continuation of the housing bubble.
Fifth, and finally, the long period of global economic stability and growth that immediately preceded the crisis, beginning in the mid- to late 1980s and since known as the âGreat Moderation,â had convinced many U.S. banking executives, government officials, and economists that extreme economic volatility was a thing of the past. That confident attitudeâtogether with an ideological climate emphasizing deregulation and the ability of financial firms to police themselvesâled almost all of them to ignore or discount clear signs of an impending crisis and, in the case of bankers, to continue reckless lending, borrowing, and securitization practices.
## Key events of the crisis
Beginning in 2004 a series of developments portended the coming crisis, though very few economists anticipated its vast scale. Over a two-year period (June 2004 to June 2006) the Fed raised the [federal funds rate](https://www.britannica.com/money/federal-funds-rate) from 1.25 to 5.25 percent, inevitably resulting in more defaults from subprime borrowers holding [adjustable-rate mortgages](https://www.britannica.com/topic/adjustable-rate-mortgage) (ARMs). Partly because of the rate increase, but also because the housing market had reached a saturation point, home sales, and thus home prices, began to fall in 2005. Many [subprime mortgage](https://www.britannica.com/money/subprime-mortgage) holders were unable to rescue themselves by borrowing, refinancing, or selling their homes, because there were fewer buyers and because many mortgage holders now owed more on their loans than their homes were worth (they were âunderwaterâ)âan increasingly common phenomenon as the crisis developed. As more and more subprime borrowers defaulted and as home prices continued to slide, MBSs based on subprime mortgages lost value, with dire consequences for the portfolios of many banks and investment firms. Indeed, because MBSs generated from the U.S. housing market had also been bought and sold in other countries (notably in western Europe), many of which had experienced their own housing bubbles, it quickly became apparent that the trouble in the [United States](https://www.britannica.com/place/United-States) would have global implications, though most experts insisted that the problems were not as serious as they appeared and that damage to financial markets could be contained.
By 2007 the steep decline in the value of MBSs had caused major losses at many banks, [hedge funds](https://www.britannica.com/money/hedge-fund), and mortgage lenders and forced even some large and prominent firms to liquidate hedge funds that were invested in MBSs, to appeal to the government for loans, to seek mergers with healthier companies, or to declare [bankruptcy](https://www.britannica.com/money/bankruptcy). Even firms that were not immediately threatened sustained losses in the billions of dollars, as the MBSs in which they had invested so heavily were now downgraded by credit-rating agencies, becoming âtoxicâ (essentially worthless) assets. (Such agencies were later accused of a severe conflict of interest, because their services were paid for by the same banks whose debt securities they rated. That financial relationship initially created an incentive for agencies to assign deceptively high ratings to some MBSs, according to critics.) In April 2007 New Century Financial Corp., one of the largest subprime lenders, filed for bankruptcy, and soon afterward many other subprime lenders ceased operations. Because they could no longer fund subprime loans through the sale of MBSs, banks stopped lending to subprime customers, causing home sales and home prices to decline further, which discouraged home buying even among consumers with prime credit ratings, further depressing sales and prices. In August, Franceâs largest bank, [BNP Paribas](https://www.britannica.com/money/BNP-Paribas), announced billions of dollars in losses, and another large U.S. firm, American Home Mortgage Investment Corp., declared bankruptcy.
In part because it was difficult to determine the extent of subprime debt in any given [MBS](https://www.britannica.com/money/mortgage-backed-security) (because MBSs were typically sold in pieces, mixed with other debt, and resold in capital markets as new securities in a process that could continue indefinitely), it was also difficult to assess the strength of bank portfolios containing MBSs as assets, even for the bank that owned them. Consequently, banks began to doubt one anotherâs solvency, which led to a freeze in the federal funds market with potentially disastrous consequences. In early August the Fed began purchasing federal funds (in the form of government securities) to provide banks with more liquidity and thereby reduce the federal funds rate, which had briefly exceeded the Fedâs target of 5.25 percent. Central banks in other parts of the worldânotably in the [European Union](https://www.britannica.com/topic/European-Union), Australia, Canada, and Japanâconducted similar [open-market operations](https://www.britannica.com/money/open-market-operation). The Fedâs intervention, however, ultimately failed to stabilize the U.S. [financial market](https://www.britannica.com/money/financial-market), forcing the Fed to directly reduce the federal funds rate three times between September and December, to 4.25 percent. During the same period, the fifth largest mortgage lender in the United Kingdom, Northern Rock, ran out of liquid assets and appealed to the [Bank of England](https://www.britannica.com/money/Bank-of-England) for a loan. News of the bailout created panic among depositors and resulted in the first bank runs in the United Kingdom in 150 years. Northern Rock was nationalized by the British government in February 2008.
The crisis in the United States deepened in January 2008 as [Bank of America](https://www.britannica.com/money/Bank-of-America-Corporation) agreed to purchase Countrywide Financial, once the countryâs leading mortgage lender, for \$4 billion in stock, a fraction of the companyâs former value. In March the prestigious [Wall Street](https://www.britannica.com/money/Wall-Street-New-York-City) investment firm [Bear Stearns](https://www.britannica.com/topic/Bear-Stearns), having exhausted its liquid assets, was purchased by [JPMorgan Chase](https://www.britannica.com/money/JPMorgan-Chase-and-Co), which itself had sustained billions of dollars in losses. Fearing that Bear Stearnsâs bankruptcy would threaten other major banks from which it had borrowed, the Fed facilitated the sale by assuming \$30 billion of the firmâs high-risk assets. Meanwhile, the Fed initiated another round of reductions in the federal funds rate, from 4.25 percent in early January to only 2 percent in April (the rate was reduced again later in the year, to 1 percent by the end of October and to effectively 0 percent in December). Although the rate cuts and other interventions during the first half of the year had some stabilizing effect, they did not end the crisis; indeed, the worst was yet to come.
By the summer of 2008 [Fannie Mae](https://www.britannica.com/money/Fannie-Mae) (the Federal National Mortgage Association) and [Freddie Mac](https://www.britannica.com/money/Freddie-Mac) (the Federal Home Loan Mortgage Corporation), the federally chartered corporations that dominated the secondary mortgage market (the market for buying and selling mortgage loans) were in serious trouble. Both institutions had been established to provide liquidity to mortgage lenders by buying mortgage loans and either holding them or selling themâwith a guarantee of principal and interest paymentsâto other banks and investors. Both were authorized to sell mortgage loans as MBSs. As the share of subprime mortgages among all home loans began to increase in the early 2000s (partly because of policy changes designed to boost home ownership among low-income and minority groups), the portfolios of Fannie Mae and Freddie Mac became more risky, as their liabilities would be huge should large numbers of mortgage holders default on their loans. Once MBSs created from subprime loans lost value and eventually became toxic, Fannie Mae and Freddie Mac suffered enormous losses and faced bankruptcy. To prevent their collapse, the [U.S. Treasury Department](https://www.britannica.com/topic/US-Department-of-the-Treasury) nationalized both corporations in September, replacing their directors and pledging to cover their debts, which then amounted to some \$1.6 trillion.
Later that month the 168-year-old [investment bank](https://www.britannica.com/money/investment-bank) [Lehman Brothers, with \$639 billion in assets, filed the largest bankruptcy in U.S. history](https://www.britannica.com/event/bankruptcy-of-Lehman-Brothers). Its failure created lasting turmoil in financial markets worldwide, severely weakened the portfolios of the banks that had loaned it money, and fostered new distrust among banks, leading them to further reduce interbank lending. Although Lehman had tried to find partners or buyers and had hoped for government assistance to facilitate a deal, the Treasury Department refused to intervene, citing âmoral hazardâ (in this case, the risk that rescuing Lehman would encourage future reckless behaviour by other banks, which would assume that they could rely on government assistance as a last resort). Only one day later, however, the Fed agreed to loan American International Group (AIG), the countryâs largest insurance company, \$85 billion to cover losses related to its sale of [credit default swaps](https://www.britannica.com/money/credit-default-swap) (CDSs), a financial contract that protects holders of various debt instruments, including MBSs, in the event of default on the underlying loans. Unlike Lehman, AIG was deemed âtoo big to fail,â because its collapse would likely cause the failure of many banks that had bought CDSs to insure their purchases of MBSs, which were now worthless. Less than two weeks after Lehmanâs demise, Washington Mutual, the countryâs largest savings and loan, was seized by federal regulators and sold the next day to [JPMorgan Chase](https://www.britannica.com/money/JPMorgan-Chase-and-Co).
By this time there was general agreement among economists and Treasury Department officials that a more forceful government response was necessary to prevent a complete breakdown of the financial system and lasting damage to the U.S. economy. In September the [George W. Bush](https://www.britannica.com/biography/George-W-Bush) administration proposed legislation, the [Emergency Economic Stabilization Act](https://www.britannica.com/money/Emergency-Economic-Stabilization-Act-of-2008) (EESA), which would establish a [Troubled Asset Relief Program](https://www.britannica.com/topic/Troubled-Asset-Relief-Program) (TARP), under which the Secretary of the Treasury, [Henry Paulson](https://www.britannica.com/money/Henry-Paulson), would be authorized to purchase from U.S. banks up to \$700 billion in MBSs and other âtroubled assets.â After the legislation was initially rejected by the [House of Representatives](https://www.britannica.com/topic/House-of-Representatives-United-States-government), a majority of whose members perceived it as an unfair bailout of Wall Street banks, it was amended and passed in the [Senate](https://www.britannica.com/topic/Senate-United-States-government). As the countryâs financial system continued to deteriorate, several representatives changed their minds, and the House passed the legislation on October 3, 2008; President Bush signed it the same day.
It soon became apparent, however, that the governmentâs purchase of MBSs would not provide sufficient liquidity in time to avert the failure of several more banks. Paulson was therefore authorized to use up to \$250 billion in TARP funds to purchase preferred stock in troubled financial institutions, making the federal government a part-owner of more than 200 banks by the end of the year. The Fed thereafter undertook a variety of extraordinary quantitative-easing (QE) measures, under several overlapping but differently named programs, which were designed to use money created by the Fed to inject liquidity into capital markets and thereby to stimulate [economic growth](https://www.britannica.com/money/economic-growth). Similar interventions were undertaken by central banks in other countries. The Fedâs measures included the purchase of long-term U.S. Treasury bonds and MBSs for prime mortgage loans, loan facilities for holders of high-rated securities, and the purchase of MBSs and other debt held by Fannie Mae and Freddie Mac. By the time the QE programs were officially ended in 2014, the Fed had by such means pumped more than \$4 trillion into the U.S. economy. Despite warnings from some economists that the creation of trillions of dollars of new money would lead to hyperinflation, the U.S. [inflation](https://www.britannica.com/money/inflation-economics) rate remained below the Fedâs target rate of 2 percent through the end of 2014.
There is now general agreement that the measures taken by the Fed to protect the U.S. financial system and to spur economic growth helped to prevent a global economic catastrophe. In the United States, recovery from the worst effects of the [Great Recession](https://www.britannica.com/money/great-recession) was also aided by the [American Recovery and Reinvestment Act](https://www.britannica.com/topic/American-Recovery-and-Reinvestment-Act), a \$787 billion stimulus and relief program proposed by the [Barack Obama](https://www.britannica.com/biography/Barack-Obama) administration and adopted by [Congress](https://www.britannica.com/topic/Congress-of-the-United-States) in February 2009. By the middle of that year, financial markets had begun to revive, and the economy had begun to grow after nearly two years of deep [recession](https://www.britannica.com/money/recession). In 2010 Congress adopted the [Wall Street Reform and Consumer Protection Act](https://www.britannica.com/money/Dodd-Frank-Act) (the [Dodd-Frank Act](https://www.britannica.com/money/dodd-frank-act-overview)), which instituted banking regulations to prevent another financial crisis and created a [Consumer Financial Protection Bureau](https://www.britannica.com/money/Consumer-Financial-Protection-Bureau), which was charged with regulating, among other things, subprime mortgage loans and other forms of [consumer credit](https://www.britannica.com/money/consumer-credit). After 2017, however, many provisions of the Dodd-Frank Act were rolled back or effectively neutered by a [Republican](https://www.britannica.com/topic/Republican-Party)\-controlled Congress and the [Donald J. Trump](https://www.britannica.com/biography/Donald-Trump) administration, both of which were hostile to the lawâs approach.

Date:
2007 - 2008
**financial crisis of 2007â08**, severe contraction of liquidity in global financial markets that originated in the [United States](https://www.britannica.com/place/United-States) as a result of the collapse of the U.S. [housing market](https://www.britannica.com/money/real-property). It threatened to destroy the international financial system; caused the failure (or near-failure) of several major [investment](https://www.britannica.com/money/investment-bank) and [commercial banks](https://www.britannica.com/money/commercial-bank), [mortgage](https://www.britannica.com/money/mortgage) lenders, [insurance](https://www.britannica.com/money/insurance) companies, and [savings and loan associations](https://www.britannica.com/money/savings-and-loan-association); and precipitated the [Great Recession](https://www.britannica.com/money/great-recession) (2007â09), the worst economic downturn since the [Great Depression](https://www.britannica.com/event/Great-Depression) (1929â*c.* 1939).
## Causes of the crisis
Although the exact causes of the financial crisis are a matter of dispute among economists, there is general agreement regarding the factors that played a role (experts disagree about their relative importance).
First, the [Federal Reserve](https://www.britannica.com/money/Federal-Reserve-System) (Fed), the [central bank](https://www.britannica.com/money/central-bank) of the United States, having anticipated a mild [recession](https://www.britannica.com/money/recession) that began in 2001, reduced the [federal funds rate](https://www.britannica.com/money/federal-funds-rate) (the [interest](https://www.britannica.com/money/interest-economics) rate that [banks](https://www.britannica.com/money/bank) charge each other for overnight loans of federal fundsâi.e., balances held at a Federal Reserve bank) 11 times between May 2000 and December 2001, from 6.5 percent to 1.75 percent. That significant decrease enabled banks to extend [consumer credit](https://www.britannica.com/money/consumer-credit) at a lower prime rate (the [interest rate](https://www.britannica.com/money/interest-rates) that banks charge to their âprime,â or low-risk, customers, generally three percentage points above the federal funds rate) and encouraged them to lend even to âsubprime,â or high-risk, customers, though at higher interest rates (*see* [subprime lending](https://www.britannica.com/money/subprime-lending)). Consumers took advantage of the cheap credit to purchase durable goods such as appliances, automobiles, and especially houses. The result was the creation in the late 1990s of a âhousing bubbleâ (a rapid increase in home prices to levels well beyond their fundamental, or intrinsic, value, driven by excessive speculation).
Second, owing to changes in banking laws beginning in the 1980s, banks were able to offer to subprime customers [mortgage](https://www.britannica.com/money/mortgage) loans that were structured with balloon payments (unusually large payments that are due at or near the end of a loan period) or adjustable interest rates (rates that remain fixed at relatively low levels for an initial period and float, generally with the federal funds rate, thereafter). As long as home prices continued to increase, subprime borrowers could protect themselves against high mortgage payments by refinancing, borrowing against the increased value of their homes, or selling their homes at a profit and paying off their mortgages. In the case of default, banks could repossess the property and sell it for more than the amount of the original loan. Subprime lending thus represented a lucrative investment for many banks. Accordingly, many banks aggressively marketed subprime loans to customers with poor credit or few assets, knowing that those borrowers could not afford to repay the loans and often misleading them about the risks involved. As a result, the share of [subprime mortgages](https://www.britannica.com/money/subprime-mortgage) among all home loans increased from about 2.5 percent to nearly 15 percent per year from the late 1990s to 2004â07.
Third, contributing to the growth of subprime lending was the widespread practice of [securitization](https://www.britannica.com/money/securitization), whereby banks bundled together hundreds or even thousands of subprime mortgages and other, less-risky forms of consumer [debt](https://www.britannica.com/money/debt) and sold them (or pieces of them) in capital markets as [securities](https://www.britannica.com/money/security-business-economics) (bonds) to other banks and investors, including hedge funds and pension funds. Bonds consisting primarily of mortgages became known as [mortgage-backed securities](https://www.britannica.com/money/mortgage-backed-security), or MBSs, which entitled their purchasers to a share of the interest and principal payments on the underlying loans. Selling subprime mortgages as MBSs was considered a good way for banks to increase their liquidity and reduce their exposure to risky loans, while purchasing MBSs was viewed as a good way for banks and investors to diversify their portfolios and earn money. As home prices continued their meteoric rise through the early 2000s, MBSs became widely popular, and their prices in capital markets increased accordingly.

## Key events of the crisis
Beginning in 2004 a series of developments portended the coming crisis, though very few economists anticipated its vast scale. Over a two-year period (June 2004 to June 2006) the Fed raised the [federal funds rate](https://www.britannica.com/money/federal-funds-rate) from 1.25 to 5.25 percent, inevitably resulting in more defaults from subprime borrowers holding [adjustable-rate mortgages](https://www.britannica.com/topic/adjustable-rate-mortgage) (ARMs). Partly because of the rate increase, but also because the housing market had reached a saturation point, home sales, and thus home prices, began to fall in 2005. Many [subprime mortgage](https://www.britannica.com/money/subprime-mortgage) holders were unable to rescue themselves by borrowing, refinancing, or selling their homes, because there were fewer buyers and because many mortgage holders now owed more on their loans than their homes were worth (they were âunderwaterâ)âan increasingly common phenomenon as the crisis developed. As more and more subprime borrowers defaulted and as home prices continued to slide, MBSs based on subprime mortgages lost value, with dire consequences for the portfolios of many banks and investment firms. Indeed, because MBSs generated from the U.S. housing market had also been bought and sold in other countries (notably in western Europe), many of which had experienced their own housing bubbles, it quickly became apparent that the trouble in the [United States](https://www.britannica.com/place/United-States) would have global implications, though most experts insisted that the problems were not as serious as they appeared and that damage to financial markets could be contained.
By 2007 the steep decline in the value of MBSs had caused major losses at many banks, [hedge funds](https://www.britannica.com/money/hedge-fund), and mortgage lenders and forced even some large and prominent firms to liquidate hedge funds that were invested in MBSs, to appeal to the government for loans, to seek mergers with healthier companies, or to declare [bankruptcy](https://www.britannica.com/money/bankruptcy). Even firms that were not immediately threatened sustained losses in the billions of dollars, as the MBSs in which they had invested so heavily were now downgraded by credit-rating agencies, becoming âtoxicâ (essentially worthless) assets. (Such agencies were later accused of a severe conflict of interest, because their services were paid for by the same banks whose debt securities they rated. That financial relationship initially created an incentive for agencies to assign deceptively high ratings to some MBSs, according to critics.) In April 2007 New Century Financial Corp., one of the largest subprime lenders, filed for bankruptcy, and soon afterward many other subprime lenders ceased operations. Because they could no longer fund subprime loans through the sale of MBSs, banks stopped lending to subprime customers, causing home sales and home prices to decline further, which discouraged home buying even among consumers with prime credit ratings, further depressing sales and prices. In August, Franceâs largest bank, [BNP Paribas](https://www.britannica.com/money/BNP-Paribas), announced billions of dollars in losses, and another large U.S. firm, American Home Mortgage Investment Corp., declared bankruptcy.
In part because it was difficult to determine the extent of subprime debt in any given [MBS](https://www.britannica.com/money/mortgage-backed-security) (because MBSs were typically sold in pieces, mixed with other debt, and resold in capital markets as new securities in a process that could continue indefinitely), it was also difficult to assess the strength of bank portfolios containing MBSs as assets, even for the bank that owned them. Consequently, banks began to doubt one anotherâs solvency, which led to a freeze in the federal funds market with potentially disastrous consequences. In early August the Fed began purchasing federal funds (in the form of government securities) to provide banks with more liquidity and thereby reduce the federal funds rate, which had briefly exceeded the Fedâs target of 5.25 percent. Central banks in other parts of the worldânotably in the [European Union](https://www.britannica.com/topic/European-Union), Australia, Canada, and Japanâconducted similar [open-market operations](https://www.britannica.com/money/open-market-operation). The Fedâs intervention, however, ultimately failed to stabilize the U.S. [financial market](https://www.britannica.com/money/financial-market), forcing the Fed to directly reduce the federal funds rate three times between September and December, to 4.25 percent. During the same period, the fifth largest mortgage lender in the United Kingdom, Northern Rock, ran out of liquid assets and appealed to the [Bank of England](https://www.britannica.com/money/Bank-of-England) for a loan. News of the bailout created panic among depositors and resulted in the first bank runs in the United Kingdom in 150 years. Northern Rock was nationalized by the British government in February 2008.
The crisis in the United States deepened in January 2008 as [Bank of America](https://www.britannica.com/money/Bank-of-America-Corporation) agreed to purchase Countrywide Financial, once the countryâs leading mortgage lender, for \$4 billion in stock, a fraction of the companyâs former value. In March the prestigious [Wall Street](https://www.britannica.com/money/Wall-Street-New-York-City) investment firm [Bear Stearns](https://www.britannica.com/topic/Bear-Stearns), having exhausted its liquid assets, was purchased by [JPMorgan Chase](https://www.britannica.com/money/JPMorgan-Chase-and-Co), which itself had sustained billions of dollars in losses. Fearing that Bear Stearnsâs bankruptcy would threaten other major banks from which it had borrowed, the Fed facilitated the sale by assuming \$30 billion of the firmâs high-risk assets. Meanwhile, the Fed initiated another round of reductions in the federal funds rate, from 4.25 percent in early January to only 2 percent in April (the rate was reduced again later in the year, to 1 percent by the end of October and to effectively 0 percent in December). Although the rate cuts and other interventions during the first half of the year had some stabilizing effect, they did not end the crisis; indeed, the worst was yet to come.
By the summer of 2008 [Fannie Mae](https://www.britannica.com/money/Fannie-Mae) (the Federal National Mortgage Association) and [Freddie Mac](https://www.britannica.com/money/Freddie-Mac) (the Federal Home Loan Mortgage Corporation), the federally chartered corporations that dominated the secondary mortgage market (the market for buying and selling mortgage loans) were in serious trouble. Both institutions had been established to provide liquidity to mortgage lenders by buying mortgage loans and either holding them or selling themâwith a guarantee of principal and interest paymentsâto other banks and investors. Both were authorized to sell mortgage loans as MBSs. As the share of subprime mortgages among all home loans began to increase in the early 2000s (partly because of policy changes designed to boost home ownership among low-income and minority groups), the portfolios of Fannie Mae and Freddie Mac became more risky, as their liabilities would be huge should large numbers of mortgage holders default on their loans. Once MBSs created from subprime loans lost value and eventually became toxic, Fannie Mae and Freddie Mac suffered enormous losses and faced bankruptcy. To prevent their collapse, the [U.S. Treasury Department](https://www.britannica.com/topic/US-Department-of-the-Treasury) nationalized both corporations in September, replacing their directors and pledging to cover their debts, which then amounted to some \$1.6 trillion.
Later that month the 168-year-old [investment bank](https://www.britannica.com/money/investment-bank) [Lehman Brothers, with \$639 billion in assets, filed the largest bankruptcy in U.S. history](https://www.britannica.com/event/bankruptcy-of-Lehman-Brothers). Its failure created lasting turmoil in financial markets worldwide, severely weakened the portfolios of the banks that had loaned it money, and fostered new distrust among banks, leading them to further reduce interbank lending. Although Lehman had tried to find partners or buyers and had hoped for government assistance to facilitate a deal, the Treasury Department refused to intervene, citing âmoral hazardâ (in this case, the risk that rescuing Lehman would encourage future reckless behaviour by other banks, which would assume that they could rely on government assistance as a last resort). Only one day later, however, the Fed agreed to loan American International Group (AIG), the countryâs largest insurance company, \$85 billion to cover losses related to its sale of [credit default swaps](https://www.britannica.com/money/credit-default-swap) (CDSs), a financial contract that protects holders of various debt instruments, including MBSs, in the event of default on the underlying loans.

Less than two weeks after Lehmanâs demise, Washington Mutual, the countryâs largest savings and loan, was seized by federal regulators and sold the next day to [JPMorgan Chase](https://www.britannica.com/money/JPMorgan-Chase-and-Co).
By this time there was general agreement among economists and Treasury Department officials that a more forceful government response was necessary to prevent a complete breakdown of the financial system and lasting damage to the U.S. economy. In September the [George W. Bush](https://www.britannica.com/biography/George-W-Bush) administration proposed legislation, the [Emergency Economic Stabilization Act](https://www.britannica.com/money/Emergency-Economic-Stabilization-Act-of-2008) (EESA), which would establish a [Troubled Asset Relief Program](https://www.britannica.com/topic/Troubled-Asset-Relief-Program) (TARP), under which the Secretary of the Treasury, [Henry Paulson](https://www.britannica.com/money/Henry-Paulson), would be authorized to purchase from U.S. banks up to \$700 billion in MBSs and other âtroubled assets.â After the legislation was initially rejected by the [House of Representatives](https://www.britannica.com/topic/House-of-Representatives-United-States-government), a majority of whose members perceived it as an unfair bailout of Wall Street banks, it was amended and passed in the [Senate](https://www.britannica.com/topic/Senate-United-States-government). As the countryâs financial system continued to deteriorate, several representatives changed their minds, and the House passed the legislation on October 3, 2008; President Bush signed it the same day.
It soon became apparent, however, that the governmentâs purchase of MBSs would not provide sufficient liquidity in time to avert the failure of several more banks. Paulson was therefore authorized to use up to \$250 billion in TARP funds to purchase preferred stock in troubled financial institutions, making the federal government a part-owner of more than 200 banks by the end of the year. The Fed thereafter undertook a variety of extraordinary quantitative-easing (QE) measures, under several overlapping but differently named programs, which were designed to use money created by the Fed to inject liquidity into capital markets and thereby to stimulate [economic growth](https://www.britannica.com/money/economic-growth). Similar interventions were undertaken by central banks in other countries. The Fedâs measures included the purchase of long-term U.S. Treasury bonds and MBSs for prime mortgage loans, loan facilities for holders of high-rated securities, and the purchase of MBSs and other debt held by Fannie Mae and Freddie Mac. By the time the QE programs were officially ended in 2014, the Fed had by such means pumped more than \$4 trillion into the U.S. economy. Despite warnings from some economists that the creation of trillions of dollars of new money would lead to hyperinflation, the U.S. [inflation](https://www.britannica.com/money/inflation-economics) rate remained below the Fedâs target rate of 2 percent through the end of 2014.
There is now general agreement that the measures taken by the Fed to protect the U.S. financial system and to spur economic growth helped to prevent a global economic catastrophe. In the United States, recovery from the worst effects of the [Great Recession](https://www.britannica.com/money/great-recession) was also aided by the [American Recovery and Reinvestment Act](https://www.britannica.com/topic/American-Recovery-and-Reinvestment-Act), a \$787 billion stimulus and relief program proposed by the [Barack Obama](https://www.britannica.com/biography/Barack-Obama) administration and adopted by [Congress](https://www.britannica.com/topic/Congress-of-the-United-States) in February 2009. By the middle of that year, financial markets had begun to revive, and the economy had begun to grow after nearly two years of deep [recession](https://www.britannica.com/money/recession). In 2010 Congress adopted the [Wall Street Reform and Consumer Protection Act](https://www.britannica.com/money/Dodd-Frank-Act) (the [Dodd-Frank Act](https://www.britannica.com/money/dodd-frank-act-overview)), which instituted banking regulations to prevent another financial crisis and created a [Consumer Financial Protection Bureau](https://www.britannica.com/money/Consumer-Financial-Protection-Bureau), which was charged with regulating, among other things, subprime mortgage loans and other forms of [consumer credit](https://www.britannica.com/money/consumer-credit). After 2017, however, many provisions of the Dodd-Frank Act were rolled back or effectively neutered by a [Republican](https://www.britannica.com/topic/Republican-Party)\-controlled Congress and the [Donald J. Trump](https://www.britannica.com/biography/Donald-Trump) administration, both of which were hostile to the lawâs approach. |
