Charles Plosser thinks there's a ticking time bomb at the Fed

``The Philadelphia Fed president, viewed as one of the bank's leading hawks, is worried about some $2.5 trillion in "excess" reserves. That is, loanable funds available to individual or corporate borrowers through the nation's banks... "These reserves are not inflationary right now," Plosser said in a meeting Tuesday with reporters in Washington. Yet if borrowing begins to surge and those reserves start to pour out of the banking system, Plosser worries, "that's going to put pressure on inflation." The result: the Fed could be forced to raise interest rates faster and earlier than it would like and perhaps slam the breaks on the economic recovery.''
