MarketWatch writes "Brokers threatened by run on shadow bank system". The piece is subtitled, "Regulators eye $10 trillion market that boomed outside traditional banking," citing comments by Timothy Geithner, president of the Federal Reserve Bank of New York, Henry Paulson, Secretary of the Treasury, and others on expanding regulation. MarketWatch says, "In recent decades, lots of new businesses and investment vehicles have evolved ... outside the purview of traditional banking regulation. Instead of getting money from depositors, these financial intermediaries often borrow by selling commercial paper, which is a type of short-term loan that has to be re-financed over and over again."
