caption_attribution_description: English: Image from Economist Mark Zandi's FCIC Testimony Explanation From Economist Mark Zandi's January 2010 testimony to the Financial Crisis Inquiry Commission: "The securitization markets also remain impaired, as investors anticipate more loan losses. Investors are also uncertain about coming legal and accounting rule changes and regulatory reforms. Private bond issuance of residential and commercial mortgage-backed securities, asset-backed securities, and CDOs peaked in 2006 at close to $2 trillion...In 2009, private issuance was less than $150 billion, and almost all of it was asset-backed issuance supported by the Federal Reserve's TALF program to aid credit card, auto and small-business lenders. Issuance of residential and commercial mortgage-backed securities and CDOs remains dormant."[1] Banks and other financial institutions packaged various types of loans (including mortgages) into securities and sold them to global investors. This is called securitization. In exchange for purchasing the investment, the investor receives a right to the cash flows from the underlying loans specified for the security. The chart shows how this financing source dried-up, meaning that non-prime mortgages and other types of loans could not be originated and sold to investors. ↑ Testimony of Mark Zandi to Financial Crisis Inquiry Commission-January 2010
context_page_description: The financial crisis of 2007–2008, also known as the global financial crisis, was a severe worldwide financial crisis. Excessive risk-taking by banks combined with the bursting of the United States housing bubble caused the values of securities tied to U.S. real estate to plummet, damaging financial institutions globally, culminating with the bankruptcy of Lehman Brothers on September 15, 2008, and an international banking crisis. The crisis sparked the Great Recession, which, at the time, was the most severe global recession since the Great Depression. It was also followed by the European debt crisis, which began with a deficit in Greece in late 2009, and the 2008–2011 Icelandic financial crisis, which involved the bank failure of all three of the major banks in Iceland and, relative to the size of its economy, was the largest economic collapse suffered by any country in economic history.
  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. The increase in cash out refinancings, as home values rose, fueled an increase in consumption that could no longer be sustained when home prices declined.
context_section_description: There is strong evidence that the riskiest, worst performing mortgages were funded through the "shadow banking system" and that competition from the shadow banking system may have pressured more traditional institutions to lower their underwriting standards and originate riskier loans.
  In a June 2008 speech, President and CEO of the Federal Reserve Bank of New York Timothy Geithner—who in 2009 became United States Secretary of the 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 of Asset–liability mismatch, meaning that they borrowed short-term in liquid markets to purchase long-term, illiquid and risky assets. This meant that disruptions in credit markets would force them to engage in 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 tri-party repo grew to $2.5 trillion. Assets held in hedge funds grew to roughly $1.8 trillion. The combined balance sheets of the five largest 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. The combined effect of these factors was a financial system vulnerable to self-reinforcing asset price and credit cycles.
  Economist Paul Krugman, laureate of the Nobel Memorial Prize in Economic Sciences, described the run on the shadow banking system as the "core of what happened" to cause the crisis. He referred to this lack of controls as "malign neglect" and argued that regulation should have been imposed on all banking-like activity. 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, at that time the traditional banking system did not have the capital to close this gap: "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 were "likely to vanish forever, having been an artifact of excessively loose credit conditions". While traditional banks raised their lending standards, it was the collapse of the shadow banking system that was the primary cause of the reduction in funds available for borrowing.
  The securitization markets supported by the shadow banking system started to close down in the spring of 2007 and nearly shut-down in the fall of 2008. More than a third of the private credit markets thus became unavailable as a source of funds. According to the Brookings Institution in June 2009, the traditional banking system did not have the capital to close this gap: "It would take a number of years of strong profits to generate sufficient capital to support that additional lending volume" and some forms of securitization are "likely to vanish forever, having been an artifact of excessively loose credit conditions".
