The Federal Reserve's massive stimulus program had little impact on the U.S. economy besides weakening the dollar and helping U.S. exports, Federal Reserve Governor Alan Greenspan told CNBC.
In a blunt critique of his successor, Fed Chairman Ben Bernanke, Greenspan said the $2 trillion in quantative easing over the past two years had done little to loosen credit and boost the economy.
"There is no evidence that huge inflow of money into the system basically worked," Greenspan said in a live interview.
