A second leg of the liquidity management engineered over the weekend to respond to the failure of Lehman Brothers is that seven banks and three investment banks established a US$70 billion liquidity facility with which to assist each other.Each of the ten pledged US$7 billion and any one of them may borrow a third of the total.The ten are Bank of America, Barclays, Citigroup, Credit Suisse, Deutsche Bank, Goldman Sachs,  JPMorgan Chase, Morgan Stanley, Merrill Lynch and UBS.So that's really nine, with Bank of America chipping in US$14 billion.Bank of America, of course, switched its rescue of a troubled Wall Street investment bank late last week from Lehman Brothers to Merrill Lynch.B of A will buy Merrill Lynch in an all-stock deal.
