The Global Financial Crisis has been called by leading economists the worst financial crisis since the one related to the Great Depression of the 1930s. It contributed to the failure of key businesses, declines in consumer wealth estimated in the trillions of U.S. dollars, substantial financial commitments incurred by governments, and a significant decline in economic activity. Many causes have been proposed, with varying weight assigned by experts. Both market-based and regulatory solutions have been implemented or are under consideration, while significant risks remain for the world economy.

The collapse of a global housing bubble, which peaked in the U.S. in 2006, caused the values of securities tied to housing prices to plummet thereafter, damaging financial institutions globally. Questions regarding bank solvency, declines in credit availability, and damaged investor confidence had an impact on global stock markets, which suffered large losses during 2008. Economies worldwide slowed in late 2008 and early 2009 as credit tightened and international trade declined. Critics argued that credit rating agencies and investors failed to accurately price the risk involved with mortgage-related financial products, and that governments did not adjust their regulatory practices to address 21st century financial markets. Governments and central banks responded with unprecedented fiscal stimulus, monetary policy expansion, and institutional bailouts.

Background and causes

The immediate cause or trigger of the crisis was the bursting of the United States housing bubble which peaked in approximately 2005–2006. High default rates on "subprime" and adjustable rate mortgages (ARM), began to increase quickly thereafter. An increase in loan incentives such as easy initial terms and a long-term trend of rising housing prices had encouraged borrowers to assume difficult mortgages in the belief they would be able to quickly refinance at more favorable terms. However, once interest rates began to rise and housing prices started to drop moderately in 2006–2007 in many parts of the U.S., refinancing became more difficult. Defaults and foreclosure activity increased dramatically as easy initial terms expired, home prices failed to go up as anticipated, and ARM interest rates reset higher.


In the years leading up to the start of the crisis in 2007, significant amounts of foreign money flowed into the U.S. from fast-growing economies in Asia and oil-producing countries. This inflow of funds made it easier for the Federal Reserve to keep interest rates in the United States too low (by the Taylor rule) from 2002–2006 which contributed to easy credit conditions, leading to the United States housing bubble. Loans of various types (e.g., mortgage, credit card, and auto) were easy to obtain and consumers assumed an unprecedented debt load. As part of the housing and credit booms, the amount of financial agreements called mortgage-backed securities (MBS) and collateralized debt obligations (CDO), which derived their value from mortgage payments and housing prices, greatly increased. Such financial innovation enabled institutions and investors around the world to invest in the U.S. housing market. As housing prices declined, major global financial institutions that had borrowed and invested heavily in subprime MBS reported significant losses. Falling prices also resulted in homes worth less than the mortgage loan, providing a financial incentive to enter foreclosure. The ongoing foreclosure epidemic that began in late 2006 in the U.S. continues to drain wealth from consumers and erodes the financial strength of banking institutions. Defaults and losses on other loan types also increased significantly as the crisis expanded from the housing market to other parts of the economy. Total losses are estimated in the trillions of U.S. dollars globally.

While the housing and credit bubbles built, a series of factors caused the financial system to both expand and become increasingly fragile. Policymakers did not recognize the increasingly important role played by financial institutions such as investment banks and hedge funds, also known as the shadow banking system. Some experts believe these institutions had become as important as commercial (depository) banks in providing credit to the U.S. economy, but they were not subject to the same regulations. These institutions as well as certain regulated banks had also assumed significant debt burdens while providing the loans described above and did not have a financial cushion sufficient to absorb large loan defaults or MBS losses. These losses impacted the ability of financial institutions to lend, slowing economic activity. Concerns regarding the stability of key financial institutions drove central banks to provide funds to encourage lending and restore faith in the commercial paper markets, which are integral to funding business operations. Governments also bailed out key financial institutions and implemented economic stimulus programs, assuming significant additional financial commitments.

Growth of the housing bubble

Between 1997 and 2006, the price of the typical American house increased by 124%. During the two decades ending in 2001, the national median home price ranged from 2.9 to 3.1 times median household income. This ratio rose to 4.0 in 2004, and 4.6 in 2006. This housing bubble resulted in quite a few homeowners refinancing their homes at lower interest rates, or financing consumer spending by taking out second mortgages secured by the price appreciation.

In a Peabody Award winning program, NPR correspondents argued that a "Giant Pool of Money" (represented by $70 trillion in worldwide fixed income investments) sought higher yields than those offered by U.S. Treasury bonds early in the decade. Further, this pool of money had roughly doubled in size from 2000 to 2007, yet the supply of relatively safe, income generating investments had not grown as fast. Investment banks on Wall Street answered this demand with the MBS and CDO, which were assigned safe ratings by the credit rating agencies. In effect, Wall Street connected this pool of money to the mortgage market in the U.S., with enormous fees accruing to those throughout the mortgage supply chain, from the mortgage broker selling the loans, to small banks that funded the brokers, to the giant investment banks behind them. By approximately 2003, the supply of mortgages originated at traditional lending standards had been exhausted. However, continued strong demand for MBS and CDO began to drive down lending standards, as long as mortgages could still be sold along the supply chain. Eventually, this speculative bubble proved unsustainable.

The CDO in particular enabled financial institutions to obtain investor funds to finance subprime and other lending, extending or increasing the housing bubble and generating large fees. A CDO essentially places cash payments from multiple mortgages or other debt obligations into a single pool, from which the cash is allocated to specific securities in a priority sequence. Those securities obtaining cash first received investment-grade ratings from rating agencies. Lower priority securities received cash thereafter, with lower credit ratings but theoretically a higher rate of return on the amount invested.

By September 2008, average U.S. housing prices had declined by over 20% from their mid-2006 peak. As prices declined, borrowers with adjustable-rate mortgages could not refinance to avoid the higher payments associated with rising interest rates and began to default. During 2007, lenders began foreclosure proceedings on nearly 1.3 million properties, a 79% increase over 2006. This increased to 2.3 million in 2008, an 81% increase vs. 2007. By August 2008, 9.2% of all U.S. mortgages outstanding were either delinquent or in foreclosure. By September 2009, this had risen to 14.4%.

Easy credit conditions

Lower interest rates encourage borrowing. From 2000 to 2003, the Federal Reserve lowered the federal funds rate target from 6.5% to 1.0%. This was done to soften the effects of the collapse of the dot-com bubble and of the September 2001 terrorist attacks, and to combat the perceived risk of deflation.

U.S.
Current Account or Trade Deficit
Additional downward pressure on interest rates was created by the USA's high and rising current account (trade) deficit, which peaked along with the housing bubble in 2006. Ben Bernanke explained how trade deficits required the U.S. to borrow money from abroad, which bid up bond prices and lowered interest rates.

Bernanke explained that between 1996 and 2004, the USA current account deficit increased by $650 billion, from 1.5% to 5.8% of GDP. Financing these deficits required the USA to borrow large sums from abroad, much of it from countries running trade surpluses, mainly the emerging economies in Asia and oil-exporting nations. The balance of payments identity requires that a country (such as the USA) running a current account deficit also have a capital account (investment) surplus of the same amount. Hence large and growing amounts of foreign funds (capital) flowed into the USA to finance its imports. This created demand for various types of financial assets, raising the prices of those assets while lowering interest rates. Foreign investors had these funds to lend, either because they had very high personal savings rates (as high as 40% in China), or because of high oil prices. Bernanke referred to this as a "saving glut." A "flood" of funds (capital or liquidity) reached the USA financial markets. Foreign governments supplied funds by purchasing USA Treasury bonds and thus avoided much of the direct impact of the crisis. USA households, on the other hand, used funds borrowed from foreigners to finance consumption or to bid up the prices of housing and financial assets. Financial institutions invested foreign funds in mortgage-backed securities.

The Fed then raised the Fed funds rate significantly between July 2004 and July 2006. This contributed to an increase in 1-year and 5-year adjustable-rate mortgage (ARM) rates, making ARM interest rate resets more expensive for homeowners. This may have also contributed to the deflating of the housing bubble, as asset prices generally move inversely to interest rates and it became riskier to speculate in housing. USA housing and financial assets dramatically declined in value after the housing bubble burst.

Sub-prime lending

U.S.
Subprime lending expanded dramatically 2004-2006


The term subprime refers to the credit quality of particular borrowers, who have weakened credit histories and a greater risk of loan default than prime borrowers. The value of U.S. subprime mortgages was estimated at $1.3 trillion as of March 2007, with over 7.5 million first-lien subprime mortgages outstanding.

In addition to easy credit conditions, there is evidence that both government and competitive pressures contributed to an increase in the amount of subprime lending during the years preceding the crisis. Major U.S. investment banks and government sponsored enterprises like Fannie Mae played an important role in the expansion of higher-risk lending.

Subprime mortgages remained below 10% of all mortgage originations until 2004, when they spiked to nearly 20% and remained there through the 2005-2006 peak of the United States housing bubble. A proximate event to this increase was the April 2004 decision by the U.S. Securities and Exchange Commission (SEC) to relax the net capital rule, which encouraged the largest five investment banks to dramatically increase their financial leverage and aggressively expand their issuance of mortgage-backed securities. This applied additional competitive pressure to Fannie Mae and Freddie Mac, which further expanded their riskier lending. Subprime mortgage payment delinquency rates remained in the 10-15% range from 1998 to 2006, then began to increase rapidly, rising to 25% by early 2008.

Some, like American Enterprise Institute fellow Peter J. Wallison, believe the roots of the crisis can be traced directly to sub-prime lending by Fannie Mae and Freddie Mac, which are government sponsored entities. On 30 September 1999, The New York Times reported that the Clinton Administration pushed for sub-prime lending: "Fannie Mae, the nation's biggest underwriter of home mortgages, has been under increasing pressure from the Clinton Administration to expand mortgage loans among low and moderate income people...In moving, even tentatively, into this new area of lending, Fannie Mae is taking on significantly more risk, which may not pose any difficulties during flush economic times. But the government-subsidized corporation may run into trouble in an economic downturn, prompting a government rescue similar to that of the savings and loan industry in the 1980s."

In 1995, the administration also tinkered with President Jimmy Carter's Community Reinvestment Act of 1977 by regulating and strengthening the anti-redlining procedures. The result was a push by the administration for greater investment, by financial institutions, into riskier loans. A 2000 United States Department of the Treasury study of lending trends for 305 cities from 1993 to 1998 showed that $467 billion of mortgage credit poured out of CRA-covered lenders into low and mid level income borrowers and neighborhoods. Nevertheless, only 25% of all sub-prime lending occurred at CRA-covered institutions, and a full 50% of sub-prime loans originated at institutions exempt from CRA.

Others have pointed out that there were not enough of these loans made to cause a crisis of this magnitude. In an article in Portfolio Magazine, Michael Lewis spoke with one trader who noted that "There weren’t enough Americans with [bad] credit taking out [bad loans] to satisfy investors’ appetite for the end product." Essentially, investment banks and hedge funds used financial innovation to synthesize more loans using derivatives. "They were creating [loans] out of whole cloth. One hundred times over! That’s why the losses are so much greater than the loans."

Predatory lending

Predatory lending refers to the practice of unscrupulous lenders, to enter into "unsafe" or "unsound" secured loans for inappropriate purposes. A classic bait-and-switch method was used by Countrywide, advertising low interest rates for home refinancing. Such loans were written into extensively detailed contracts, and swapped for more expensive loan products on the day of closing. Whereas the advertisement might state that 1% or 1.5% interest would be charged, the consumer would be put into an adjustable rate mortgage (ARM) in which the interest charged would be greater than the amount of interest paid. This created negative amortization, which the credit consumer might not notice until long after the loan transaction had been consummated.

Countrywide, sued by California Attorney General Jerry Brown for "Unfair Business Practices" and "False Advertising" was making high cost mortgages "to homeowners with weak credit, adjustable rate mortgages (ARMs) that allowed homeowners to make interest-only payments.". When housing prices decreased, homeowners in ARMs then had little incentive to pay their monthly payments, since their home equity had disappeared. This caused Countrywide's financial condition to deteriorate, ultimately resulting in a decision by the Office of Thrift Supervision to seize the lender.

Countrywide, according to Republican Lawmakers, had involved itself in making low-cost loans to politicians, for purposes of gaining political favors.

Former employees from Ameriquest, which was United States's leading wholesale lender, described a system in which they were pushed to falsify mortgage documents and then sell the mortgages to Wall Street banks eager to make fast profits. There is growing evidence that such mortgage frauds may be a cause of the crisis.

Deregulation

Critics have argued that the regulatory framework did not keep pace with financial innovation, such as the increasing importance of the shadow banking system, derivatives and off-balance sheet financing. In other cases, laws were changed or enforcement weakened in parts of the financial system. Key examples include:
  • In October 1982, President Ronald Reagan signed into Law the Garn-St. Germain Depository Institutions Act, which began the process of Banking deregulation that helped contribute to the savings and loan crises of the late 80's/early 90's, and the financial crises of 2007-2009. President Reagan stated at the signing, "all in all, I think we hit the jackpot".
  • In November 1999, President Bill Clinton signed into Law the Gramm-Leach-Bliley Act, which repealed part of the Glass-Steagall Act of 1933. This repeal has been criticized for reducing the separation between commercial banks (which traditionally had a conservative culture) and investment banks (which had a more risk-taking culture).
  • In 2004, the Securities and Exchange Commission relaxed the net capital rule, which enabled investment banks to substantially increase the level of debt they were taking on, fueling the growth in mortgage-backed securities supporting subprime mortgages. The SEC has conceded that self-regulation of investment banks contributed to the crisis.
  • Financial institutions in the shadow banking system are not subject to the same regulation as depository banks, allowing them to assume additional debt obligations relative to their financial cushion or capital base. This was the case despite the Long-Term Capital Management debacle in 1998, where a highly-leveraged shadow institution failed with systemic implications.
  • Regulators and accounting standard-setters allowed depository banks such as Citigroup to move significant amounts of assets and liabilities off-balance sheet into complex legal entities called structured investment vehicles, masking the weakness of the capital base of the firm or degree of leverage or risk taken. One news agency estimated that the top four U.S. banks will have to return between $500 billion and $1 trillion to their balance sheets during 2009. This increased uncertainty during the crisis regarding the financial position of the major banks. Off-balance sheet entities were also used by Enron as part of the scandal that brought down that company in 2001.
  • As early as 1997, Fed Chairman Alan Greenspan fought to keep the derivatives market unregulated. With the advice of the President's Working Group on Financial Markets, the U.S. Congress and President allowed the self-regulation of the over-the-counter derivatives market when they enacted the Commodity Futures Modernization Act of 2000. Derivatives such as credit default swaps (CDS) can be used to hedge or speculate against particular credit risks. The volume of CDS outstanding increased 100-fold from 1998 to 2008, with estimates of the debt covered by CDS contracts, as of November 2008, ranging from US$33 to $47 trillion. Total over-the-counter (OTC) derivative notional value rose to $683 trillion by June 2008. Warren Buffett famously referred to derivatives as "financial weapons of mass destruction" in early 2003.


Increased debt burden or over-leveraging

Leverage Ratios of Investment Banks Increased Significantly 2003-2007
U.S. households and financial institutions became increasingly indebted or overleveraged during the years preceding the crisis. This increased their vulnerability to the collapse of the housing bubble and worsened the ensuing economic downturn. Key statistics include:

  • Free cash used by consumers from home equity extraction doubled from $627 billion in 2001 to $1,428 billion in 2005 as the housing bubble built, a total of nearly $5 trillion dollars over the period, contributing to economic growth worldwide. U.S. home mortgage debt relative to GDP increased from an average of 46% during the 1990s to 73% during 2008, reaching $10.5 trillion.




  • In 1981, U.S. private debt was 123% of GDP; by the third quarter of 2008, it was 290%.


  • From 2004-07, the top five U.S. investment banks each significantly increased their financial leverage (see diagram), which increased their vulnerability to a financial shock. These five institutions reported over $4.1 trillion in debt for fiscal year 2007, about 30% of USA nominal GDP for 2007. Lehman Brothers was liquidated, Bear Stearns and Merrill Lynch were sold at fire-sale prices, and Goldman Sachs and Morgan Stanley became commercial banks, subjecting themselves to more stringent regulation. With the exception of Lehman, these companies required or received government support.




These seven entities were highly leveraged and had $9 trillion in debt or guarantee obligations, an enormous concentration of risk, yet were not subject to the same regulation as depository banks.

Financial innovation and complexity

The term financial innovation refers to the ongoing development of financial products designed to achieve particular client objectives, such as offsetting a particular risk exposure (such as the default of a borrower) or to assist with obtaining financing. Examples pertinent to this crisis included: the adjustable-rate mortgage; the bundling of subprime mortgages into mortgage-backed securities (MBS) or collateralized debt obligations (CDO) for sale to investors, a type of securitization; and a form of credit insurance called credit default swaps(CDS). The usage of these products expanded dramatically in the years leading up to the crisis. These products vary in complexity and the ease with which they can be valued on the books of financial institutions.

Certain financial innovation may also have the effect of circumventing regulations, such as off-balance sheet financing that affects the leverage or capital cushion reported by major banks. For example, Martin Wolf wrote in June 2009: "...an enormous part of what banks did in the early part of this decade – the off-balance-sheet vehicles, the derivatives and the 'shadow banking system' itself – was to find a way round regulation."

Incorrect pricing of risk

The pricing of risk refers to the incremental compensation required by investors for taking on additional risk, which may be measured by interest rates or fees. For a variety of reasons, market participants did not accurately measure the risk inherent with financial innovation such as MBS and CDO's or understand its impact on the overall stability of the financial system. For example, the pricing model for CDOs clearly did not reflect the level of risk they introduced into the system. The average recovery rate for "high quality" CDOs has been approximately 32 cents on the dollar, while the recovery rate for mezzanine CDO's has been approximately five cents for every dollar. These massive, practically unthinkable, losses have dramatically impacted the balance sheets of banks across the globe, leaving them with very little capital to continue operations.

Another example relates to AIG, which insured obligations of various financial institutions through the usage of credit default swaps. The basic CDS transaction involved AIG receiving a premium in exchange for a promise to pay money to party A in the event party B defaulted. However, AIG did not have the financial strength to support its many CDS commitments as the crisis progressed and was taken over by the government in September 2008. U.S. taxpayers provided over $180 billion in government support to AIG during 2008 and early 2009, through which the money flowed to various counterparties to CDS transactions, including many large global financial institutions.

The limitations of a widely-used financial model also were not properly understood. This formula assumed that the price of CDS was correlated with and could predict the correct price of mortgage backed securities. Because it was highly tractable, it rapidly came to be used by a huge percentage of CDO and CDS investors, issuers, and rating agencies. According to one wired.com article: "Then the model fell apart. Cracks started appearing early on, when financial markets began behaving in ways that users of Li's formula hadn't expected. The cracks became full-fledged canyons in 2008—when ruptures in the financial system's foundation swallowed up trillions of dollars and put the survival of the global banking system in serious peril... Li's Gaussian copula formula will go down in history as instrumental in causing the unfathomable losses that brought the world financial system to its knees."

As financial assets became more and more complex, and harder and harder to value, investors were reassured by the fact that both the international bond rating agencies and bank regulators, who came to rely on them, accepted as valid some complex mathematical models which theoretically showed the risks were much smaller than they actually proved to be in practice. George Soros commented that "The super-boom got out of hand when the new products became so complicated that the authorities could no longer calculate the risks and started relying on the risk management methods of the banks themselves. Similarly, the rating agencies relied on the information provided by the originators of synthetic products. It was a shocking abdication of responsibility."

Boom and collapse of the shadow banking system

In a June 2008 speech, President and CEO of the NY Federal Reserve Bank Timothy Geithner, who in 2009 became Secretary of the United States Treasury, placed significant blame for the freezing of credit markets on a "run" on the entities in the "parallel" banking system, also called the shadow banking system. These entities became critical to the credit markets underpinning the financial system, but were not subject to the same regulatory controls. Further, these entities were vulnerable because they borrowed short-term in liquid markets to purchase long-term, illiquid and risky assets. This meant that disruptions in credit markets would make them subject to rapid deleveraging, selling their long-term assets at depressed prices. He described the significance of these entities: "In early 2007, asset-backed commercial paper conduits, in structured investment vehicles, in auction-rate preferred securities, tender option bonds and variable rate demand notes, had a combined asset size of roughly $2.2 trillion. Assets financed overnight in triparty repo grew to $2.5 trillion. Assets held in hedge funds grew to roughly $1.8 trillion. The combined balance sheets of the then five major investment banks totaled $4 trillion. In comparison, the total assets of the top five bank holding companies in the United States at that point were just over $6 trillion, and total assets of the entire banking system were about $10 trillion." He stated that the "combined effect of these factors was a financial system vulnerable to self-reinforcing asset price and credit cycles."

Paul Krugman, laureate of the Nobel Prize in Economics, described the run on the shadow banking system as the "core of what happened" to cause the crisis. "As the shadow banking system expanded to rival or even surpass conventional banking in importance, politicians and government officials should have realized that they were re-creating the kind of financial vulnerability that made the Great Depression possible—and they should have responded by extending regulations and the financial safety net to cover these new institutions. Influential figures should have proclaimed a simple rule: anything that does what a bank does, anything that has to be rescued in crises the way banks are, should be regulated like a bank." He referred to this lack of controls as "malign neglect."

Commodity bubble

A commodity price bubble was created following the collapse in the housing bubble. The price of oil nearly tripled from $50 to $140 from early 2007 to 2008, before plunging as the financial crisis began to take hold in late 2008. Experts debate the causes, which include the flow of money from housing and other investments into commodities to speculation and monetary policy or the increasing feeling of raw materials scarcity in a fast growing world economy and thus positions taken on those markets, such as Chinese increasing presence in Africa.An increase in oil prices tends to divert a larger share of consumer spending into gasoline, which creates downward pressure on economic growth in oil importing countries, as wealth flows to oil-producing states.

Systemic crisis

Another analysis, different from the mainstream explanation, is that the financial crisis is merely a symptom of another, deeper crisis, which is a systemic crisis of capitalism itself. According to Samir Amin, an Egyptian economist, the constant decrease in GDP growth rates in Western countries since the early 1970s created a growing surplus of capital which did not have sufficient profitable investment outlets in the real economy. The alternative was to place this surplus into the financial market, which became more profitable than productive capital investment, especially with subsequent deregulation. According to Samir Amin, this phenomenon has led to recurrent financial bubbles (such as the internet bubble) and is the deep cause of the financial crisis of 2007-2009.

John Bellamy Foster, a political economy analyst and editor of the Monthly Review, believes that the decrease in GDP growth rates since the early 1970s is due to increasing market saturation.

John C. Bogle wrote during 2005 that a series of unresolved challenges face capitalism that have contributed to past financial crises and have not been sufficiently addressed: "Corporate America went astray largely because the power of managers went virtually unchecked by our gatekeepers for far too long...They failed to 'keep an eye on these geniuses' to whom they had entrusted the responsibility of the management of America's great corporations." He cites particular issues, including:

  • "Manager's capitalism" which he argues has replaced "owner's capitalism," meaning management runs the firm for its benefit rather than for the shareholders, a variation on the principal-agent problem;
  • Burgeoning executive compensation;
  • Managed earnings, mainly a focus on share price rather than the creation of genuine value; and
  • The failure of gatekeepers, including auditors, boards of directors, Wall Street analysts, and career politicians.


Role of economic forecasting

Dirk Bezemer in his research credits 12 economists with predicting (with supporting argument and estimates of timing) the crisis: Dean Baker (US), Wynne Godley (US), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Stephen Keen (Australia), Jakob Brøchner Madsen & Jens Kjaer Sørensen (Denmark), Kurt Richebächer (US), Nouriel Roubini(US), Peter Schiff (US), Robert Shiller(US).

A cover story in BusinessWeek Magazine claims that economists mostly failed to predict the worst international economic crisis since the Great Depression of 1930s. The Wharton School of the University of Pennsylvania online business journal examines why economists failed to predict a major global financial crisis. An article in the New York Times informs that economist Nouriel Roubini warned of such crisis as early as September 2006, and the article goes on to state that the profession of economics is bad at predicting recessions. According to The Guardian, Roubini was ridiculed for predicting a collapse of the housing market and worldwide recession, while The New York Times labelled him "Dr. Doom". However, there are examples of other experts who gave indications of a financial crisis.

Financial markets impacts

Impacts on financial institutions



The International Monetary Fund estimated that large U.S. and European banks lost more than $1 trillion on toxic assets and from bad loans from January 2007 to September 2009. These losses are expected to top $2.8 trillion from 2007-10. U.S. banks losses were forecast to hit $1 trillion and European bank losses will reach $1.6 trillion. The IMF estimated that U.S. banks were about 60 percent through their losses, but British and eurozone banks only 40 percent.

One of the first victims was Northern Rockmarker, a medium-sized Britishmarker bank. The highly leveraged nature of its business led the bank to request security from the Bank of Englandmarker. This in turn led to investor panic and a bank run in mid-September 2007. Calls by Liberal Democrat Shadow Chancellor Vince Cable to nationalise the institution were initially ignored; in February 2008, however, the British government (having failed to find a private sector buyer) relented, and the bank was taken into public hands. Northern Rock's problems proved to be an early indication of the troubles that would soon befall other banks and financial institutions.

Initially the companies affected were those directly involved in home construction and mortgage lending such as Northern Rock and Countrywide Financial, as they could no longer obtain financing through the credit markets. Over 100 mortgage lenders went bankrupt during 2007 and 2008. Concerns that investment bank Bear Stearns would collapse in March 2008 resulted in its fire-sale to JP Morgan Chase. The crisis hit its peak in September and October 2008. Several major institutions either failed, were acquired under duress, or were subject to government takeover. These included Lehman Brothers, Merrill Lynch, Fannie Mae, Freddie Mac, and AIG.

Credit markets and the shadow banking system

TED spread and components during 2008
During September 2008, the crisis hits its most critical stage. There was the equivalent of a bank run on the money market mutual funds, which frequently invest in commercial paper issued by corporations to fund their operations and payrolls. Withdrawal from money markets were $144.5 billion during one week, versus $7.1 billion the week prior. This interrupted the ability of corporations to rollover (replace) their short-term debt. The U.S. government responded by extending insurance for money market accounts analogous to bank deposit insurance via a temporary guarantee and with Federal Reserve programs to purchase commercial paper. The TED spread, an indicator of perceived credit risk in the general economy, spiked up in July 2007, remained volatile for a year, then spiked even higher in September 2008, reaching a record 4.65% on October 10, 2008.

In a dramatic meeting on September 18, 2008 Treasury Secretary Henry Paulson and Fed Chairman Ben Bernanke met with key legislators to propose a $700 billion emergency bailout. Bernanke reportedly tells them: "If we don't do this, we may not have an economy on Monday." The Emergency Economic Stabilization Act also called the Troubled Asset Relief Program (TARP) is signed into law on October 3, 2008.

Economist Paul Krugman and U.S. Treasury Secretary Timothy Geithner explain the credit crisis via the implosion of the shadow banking system, which had grown to nearly equal the importance of the traditional commercial banking sector as described above. Without the ability to obtain investor funds in exchange for most types of mortgage-backed securities or asset-backed commercial paper, investment banks and other entities in the shadow banking system could not provide funds to mortgage firms and other corporations.

This meant that nearly one-third of the U.S. lending mechanism was frozen and continued to be frozen into June 2009. According to the Brookings Institution, the traditional banking system does not have the capital to close this gap as of June 2009: "It would take a number of years of strong profits to generate sufficient capital to support that additional lending volume." The authors also indicate that some forms of securitization are "likely to vanish forever, having been an artifact of excessively loose credit conditions." While traditional banks have raised their lending standards, it was the collapse of the shadow banking system that is the primary cause of the reduction in funds available for borrowing.

Wealth effects

There is a direct relationship between declines in wealth, and declines in consumption and business investment, which along with government spending represent the economic engine. Between June 2007 and November 2008, Americans lost an estimated average of more than a quarter of their collective net worth. By early November 2008, a broad U.S. stock index the S&P 500, was down 45 percent from its 2007 high. Housing prices had dropped 20% from their 2006 peak, with futures markets signaling a 30-35% potential drop. Total home equity in the United States, which was valued at $13 trillion at its peak in 2006, had dropped to $8.8 trillion by mid-2008 and was still falling in late 2008. Total retirement assets, Americans' second-largest household asset, dropped by 22 percent, from $10.3 trillion in 2006 to $8 trillion in mid-2008. During the same period, savings and investment assets (apart from retirement savings) lost $1.2 trillion and pension assets lost $1.3 trillion. Taken together, these losses total a staggering $8.3 trillion. Since peaking in the second quarter of 2007, household wealth is down $14 trillion.

Further, U.S. homeowners had extracted significant equity in their homes in the years leading up to the crisis, which they could no longer do once housing prices collapsed. Free cash used by consumers from home equity extraction doubled from $627 billion in 2001 to $1,428 billion in 2005 as the housing bubble built, a total of nearly $5 trillion over the period. U.S. home mortgage debt relative to GDP increased from an average of 46% during the 1990s to 73% during 2008, reaching $10.5 trillion.

To offset this decline in consumption and lending capacity, the U.S. government and U.S. Federal Reserve have committed $13.9 trillion, of which $6.8 trillion has been invested or spent, as of June 2009. In effect, the Fed has gone from being the "lender of last resort" to the "lender of only resort" for a significant portion of the economy. In some cases the Fed can now be considered the "buyer of last resort."

Economist Dean Baker explained the reduction in the availability of credit this way:
"Yes, consumers and businesses can't get credit as easily as they could a year ago.
There is a really good reason for tighter credit.
Tens of millions of homeowners who had substantial equity in their homes two years ago have little or nothing today.
Businesses are facing the worst downturn since the Great Depression.
This matters for credit decisions.
A homeowner with equity in her home is very unlikely to default on a car loan or credit card debt.
They will draw on this equity rather than lose their car and/or have a default placed on their credit record.
On the other hand, a homeowner who has no equity is a serious default risk.
In the case of businesses, their creditworthiness depends on their future profits.
Profit prospects look much worse in November 2008 than they did in November 2007 (of course, to clear-eyed analysts, they didn't look too good a year ago either).
While many banks are obviously at the brink, consumers and businesses would be facing a much harder time getting credit right now even if the financial system were rock solid.
The problem with the economy is the loss of close to $6 trillion in housing wealth and an even larger amount of stock wealth.
Economists, economic policy makers and economic reporters virtually all missed the housing bubble on the way up.
If they still can't notice its impact as the collapse of the bubble throws into the worst recession in the post-war era, then they are in the wrong profession."


At the heart of the portfolios of many of these institutions were investments whose assets had been derived from bundled home mortgages. Exposure to these mortgage-backed securities, or to the credit derivatives used to insure them against failure, caused the collapse or takeover of several key firms such as Lehman Brothers, AIG, Merrill Lynch, and HBOS.

Global contagion

The crisis rapidly developed and spread into a global economic shock, resulting in a number of European bank failures, declines in various stock indexes, and large reductions in the market value of equities and commodities.

Both MBS and CDO were purchased by corporate and institutional investors globally. Derivatives such as credit default swaps also increased the linkage between large financial institutions. Moreover, the de-leveraging of financial institutions, as assets were sold to pay back obligations that could not be refinanced in frozen credit markets, further accelerated the liquidity crisis and caused a decrease in international trade.

World political leaders, national ministers of finance and central bank directors coordinated their efforts to reduce fears, but the crisis continued. At the end of October 2008 a currency crisis developed, with investors transferring vast capital resources into stronger currencies such as the yen, the dollar and the Swiss franc, leading many emergent economies to seek aid from the International Monetary Fundmarker.

Effects on the global economy

Global impact of the crisis


Global effects

A number of commentators have suggested that if the liquidity crisis continues, there could be an extended recession or worse. The continuing development of the crisis prompted fears of a global economic collapse. The financial crisis is likely to yield the biggest banking shakeout since the savings-and-loan meltdown.Investment bank UBS stated on October 6 that 2008 would see a clear global recession, with recovery unlikely for at least two years. Three days later UBS economists announced that the "beginning of the end" of the crisis had begun, with the world starting to make the necessary actions to fix the crisis: capital injection by governments; injection made systemically; interest rate cuts to help borrowers. The United Kingdom had started systemic injection, and the world's central banks were now cutting interest rates. UBS emphasized the United States needed to implement systemic injection. UBS further emphasized that this fixes only the financial crisis, but that in economic terms "the worst is still to come". UBS quantified their expected recession durations on October 16: the Eurozone's would last two quarters, the United States' would last three quarters, and the United Kingdom's would last four quarters. The economic crisis in Iceland involved all three of the country's major banks. Relative to the size of its economy, Icelandmarker’s banking collapse is the largest suffered by any country in economic history.

At the end of October UBS revised its outlook downwards: the forthcoming recession would be the worst since the Reagan recession of 1981 and 1982 with negative 2009 growth for the U.S., Eurozone, UK and Canada; very limited recovery in 2010; but not as bad as the Great Depression.

The Brookings Institution reported in June 2009 that U.S. consumption accounted for more than a third of the growth in global consumption between 2000 and 2007. "The US economy has been spending too much and borrowing too much for years and the rest of the world depended on the U.S. consumer as a source of global demand." With a recession in the U.S. and the increased savings rate of U.S. consumers, declines in growth elsewhere have been dramatic. For the first quarter of 2009, the annualized rate of decline in GDP was 14.4% in Germany, 15.2% in Japan, 7.4% in the UK, 18% in Latvia, 9.8% in the Euro area and 21.5% for Mexico.

By March 2009, the Arab world had lost $3 trillion due to the crisis. In April 2009, unemployment in the Arab world is said to be a 'time bomb'. In May 2009, the United Nations reported a drop in foreign investment in Middle-Eastern economies due to a slower rise in demand for oil. In June 2009, the World Bank predicted a tough year for Arab states. In September 2009, Arab banks reported losses of nearly $4 billion since the global financial crisis onset.

U.S. economic effects

Real gross domestic product — the output of goods and services produced by labor and property located in the United States — decreased at an annual rate of approximately 6 percent in the fourth quarter of 2008 and first quarter of 2009, versus activity in the year-ago periods. The U.S. unemployment rate increased to 10.2% by October 2009, the highest rate since 1983 and roughly twice the pre-crisis rate. The average hours per work week declined to 33, the lowest level since the government began collecting the data in 1964.

Official economic projections

On November 3, 2008, the EU-commission at Brusselsmarker predicted for 2009 an extremely weak growth of GDP, by 0.1 percent, for the countries of the Euro zone (Francemarker, Germanymarker, Italymarker, etc.) and even negative number for the UK (-1.0 percent), Irelandmarker and Spainmarker. On November 6, the IMF at Washington, D.C.marker, launched numbers predicting a worldwide recession by -0.3 percent for 2009, averaged over the developed economies. On the same day, the Bank of England and the Central Bank for the Euro zone, respectively, reduced their interest rates from 4.5 percent down to three percent, and from 3.75 percent down to 3.25 percent. Economically, mainly the car industry seems to be involved. As a consequence, starting from November 2008, several countries launched large "help packages" for their economies.

The U.S. Federal Reserve Open Market Committee release in June 2009 stated: "...the pace of economic contraction is slowing. Conditions in financial markets have generally improved in recent months. Household spending has shown further signs of stabilizing but remains constrained by ongoing job losses, lower housing wealth, and tight credit. Businesses are cutting back on fixed investment and staffing but appear to be making progress in bringing inventory stocks into better alignment with sales. Although economic activity is likely to remain weak for a time, the Committee continues to anticipate that policy actions to stabilize financial markets and institutions, fiscal and monetary stimulus, and market forces will contribute to a gradual resumption of sustainable economic growth in a context of price stability." Economic projections from the Federal Reserve and Reserve Bank Presidents include a return to typical growth levels (GDP) of 2-3% in 2010; an unemployment plateau in 2009 and 2010 around 10% with moderation in 2011; and inflation that remains at typical levels around 1-2%.

Responses to financial crisis

Emergency and short-term responses

The U.S. Federal Reserve and central banks around the world have taken steps to expand money supplies to avoid the risk of a deflationary spiral, in which lower wages and higher unemployment lead to a self-reinforcing decline in global consumption. In addition, governments have enacted large fiscal stimulus packages, by borrowing and spending to offset the reduction in private sector demand caused by the crisis. The U.S. executed two stimulus packages, totaling nearly $1 trillion during 2008 and 2009.

This credit freeze brought the global financial system to the brink of collapse. The response of the USA Federal Reserve, the European Central Bankmarker, and other central banks was immediate and dramatic. During the last quarter of 2008, these central banks purchased US$2.5 trillion of government debt and troubled private assets from banks. This was the largest liquidity injection into the credit market, and the largest monetary policy action, in world history. The governments of European nations and the USA also raised the capital of their national banking systems by $1.5 trillion, by purchasing newly issued preferred stock in their major banks.

Governments have also bailed-out a variety of firms as discussed above, incurring large financial obligations. To date, various U.S. government agencies have committed or spent trillions of dollars in loans, asset purchases, guarantees, and direct spending.

Regulatory proposals and long-term responses

American President Barack Obama and key advisers introduced a series of regulatory proposals in June 2009. The proposals address consumer protection, executive pay, bank financial cushions or capital requirements, expanded regulation of the shadow banking system and derivatives, and enhanced authority for the Federal Reserve to safely wind-down systemically important institutions, among others.

A variety of regulatory changes have been proposed by economists, politicians, journalists, and business leaders to minimize the impact of the current crisis and prevent recurrence. However, as of November 2009, many of the proposed solutions have not yet been implemented. These include:

  • Ben Bernanke: Establish resolution procedures for closing troubled financial institutions in the shadow banking system, such as investment banks and hedge funds.
  • Joseph Stiglitz: Restrict the leverage that financial institutions can assume. Require executive compensation to be more related to long-term performance. Re-instate the separation of commercial (depository) and investment banking established by the Glass-Steagall Act in 1933 and repealed in 1999 by the Gramm-Leach-Bliley Act.
  • Simon Johnson: Break-up institutions that are "too big to fail" to limit systemic risk.
  • Paul Krugman: Regulate institutions that "act like banks " similarly to banks.
  • Alan Greenspan: Banks should have a stronger capital cushion, with graduated regulatory capital requirements (i.e., capital ratios that increase with bank size), to "discourage them from becoming too big and to offset their competitive advantage."
  • Warren Buffett: Require minimum down payments for home mortgages of at least 10% and income verification.
  • Eric Dinallo: Ensure any financial institution has the necessary capital to support its financial commitments. Regulate credit derivatives and ensure they are traded on well-capitalized exchanges to limit counterparty risk.
  • Raghuram Rajan: Require financial institutions to maintain sufficient "contingent capital" (i.e., pay insurance premiums to the government during boom periods, in exchange for payments during a downturn.)
  • A. Michael Spence and Gordon Brown: Establish an early-warning system to help detect systemic risk.
  • Niall Ferguson and Jeffrey Sachs: Impose haircuts on bondholders and counterparties prior to using taxpayer money in bailouts. In other words, bondholders with a claim of $100 would have their claim reduced to $80, creating $20 in equity. This is also called a debt for equity swap. This is frequently done in bankruptcies, where the current shareholders are wiped out and the bondholders become the new stockholders, agreeing to reduce the company's debt burden in the process. This is being done with General Motors, for example.
  • Nouriel Roubini: Nationalize insolvent banks. Reduce mortgage balances to assist homeowners, giving the lender a share in any future home appreciation.
  • Adair Turner: In August 2009 in a roundtable interview in Prospect magazine Adair Turner supported the idea of new global taxes on financial transactions, warning that a “swollen” financial sector paying excessive salaries has grown too big for society. Lord Turner’s suggestion that a “Tobin tax” – named after the economist James Tobin – should be considered for financial transactions reverberated around the world.
