There is now a rising probability of a "catastrophic" financial and economic outcome; a vicious circle where a deep recession makes the financial losses more severe and where, in turn, large and growing financial losses and a financial meltdown make the recession even more severe. The Fed is seriously worried about this vicious circle and about the risks of a systemic financial meltdown....Capital reduction, credit contraction, forced liquidation and fire sales of assets at below fundamental prices will ensue leading to a cascading and mounting cycle of losses and further credit contraction. In illiquid market actual market prices are now even lower than the lower fundamental value that they now have given the credit problems in the economy. Market prices include a large illiquidity discount on top of the discount due to the credit and fundamental problems of the underlying assets that are backing the distressed financial assets. Capital losses will lead to margin calls and further reduction of risk taking by a variety of financial institutions that are now forced to mark to market their positions. Such a forced fire sale of assets in illiquid markets will lead to further losses that will further contract credit and trigger further margin calls and disintermediation of credit.
To understand the risks that the financial system is facing today I present the "nightmare" or "catastrophic" scenario that the Fed and financial officials around the world are now worried about. Such a scenario – however extreme – has a rising and significant probability of occurring. Thus, it does not describe a very low probability event but rather an outcome that is quite possible.”--from testimony before Congress.
