George Soros on Financial Markets, the Subprime Mortgage Crisis, and the Credit Crash (2008)

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[180] 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 told them: "If we don't do this, we may not have an economy on Monday." The Emergency Economic Stabilization Act, which implemented the Troubled Asset Relief Program (TARP), was 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.[132] 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.

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% 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%, 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".
