The immediate or proximate cause of the crisis in 2008 was the failure or risk of failure at major financial institutions globally, starting with the rescue of investment bank Bear Stearns in March 2008 and the failure of Lehman Brothers in September 2008. Many of these institutions had invested in risky securities that lost much or all of their value when U.S. and European housing bubbles began to deflate during the 2007-2009 period, depending on the country. Further, many institutions had become dependent on short-term (overnight) funding markets subject to disruption.[7][8]
The origin of these housing bubbles involves two major factors: 1) Low interest rates in the U.S. and Europe following the 2000-2001 U.S. recession; and 2) Significant growth in savings available from developing nations due to ongoing trade imbalances.[9] These factors drove a large increase in demand for high-yield investments. Large investment banks connected the housing markets to this large supply of savings via innovative new securities, fueling housing bubbles in the U.S. and Europe.[10]
Many institutions lowered credit standards to continue feeding the global demand for mortgage securities, generating huge profits which its investors shared. They also shared the risk. When the bubbles developed, household debt levels rose sharply after the year 2000 globally. Households became dependent on being able to refinance their mortgages. Further, U.S. households often had adjustable rate mortgages, which had lower initial interest rates and payments that later rose. When global credit markets essentially stopped funding mortgage-related investments in the 2007-2008 period, U.S. homeowners were no longer able to refinance and defaulted in record numbers, leading to the collapse of securities backed by these mortgages that now pervaded the system.[10][11]
The failure rates of subprime mortgages were the first symptom of a credit boom turned to bust and of a real estate shock. But large default rates on subprime mortgages cannot account for the severity of the crisis. Rather, low-quality mortgages acted as an accelerant to the fire that spread through the entire financial system. The latter had become fragile as a result of several factors that are unique to this crisis: the transfer of assets from the balance sheets of banks to the markets, the creation of complex and opaque assets, the failure of ratings agencies to properly assess the risk of such assets, and the application of fair value accounting. To these novel factors, one must add the now standard failure of regulators and supervisors in spotting and correcting the emerging weaknesses.[12]
Federal Reserve Chair Ben Bernanke testified in September 2010 regarding the causes of the crisis. He wrote that there were shocks or triggers (i.e., particular events that touched off the crisis) and vulnerabilities (i.e., structural weaknesses in the financial system, regulation and supervision) that amplified the shocks. Examples of triggers included: losses on subprime mortgage securities that began in 2007 and a run on the shadow banking system that began in mid-2007, which adversely affected the functioning of money markets. Examples of vulnerabilities in the private sector included: financial institution dependence on unstable sources of short-term funding such as repurchase agreements or Repos; deficiencies in corporate risk management; excessive use of leverage (borrowing to invest); and inappropriate usage of derivatives as a tool for taking excessive risks. Examples of vulnerabilities in the public sector included: statutory gaps and conflicts between regulators; ineffective use of regulatory authority; and ineffective crisis management capabilities. Bernanke also discussed "Too big to fail" institutions, monetary policy, and trade deficits.[13]
