Ben S. Bernanke, chairman of the U.S. Federal Reserve, speaks during a press conference at the Federal Reserve in Washington, D.C., U.S., on Wednesday, April 27, 2011. Bernanke said the central bank's pledge to keep interest rates low for an "extended period" means there likely will be no tightening of policy "for a couple of meetings."
