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% through their losses, but British and eurozone banks only 40% .
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 financial institution 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, Washington Mutual, Wachovia, and AIG.

Credit markets and the shadow banking system
During September 2008, the crisis hit 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.
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.
