jtomm: Before last week I said that there might be a stealth run on banks as investors move money from their cash accounts and put the proceeds into Treasuries, especially at brokerages where Treasury securities money markets yielding 4 percent are available. The money comes out of the cash "position" at the brokerage, which it is on deposit at a bank. I believe Schwab encouraged it on their homepage by "advertising" one of the money markets. How much reserves do banks have?
