Fed governor Warsh to step down next monthFederal Reserve Governor Kevin Warsh, who was one of Chairman Ben Bernanke's closest financial-crisis advisers before becoming the only governor to question the expansion of record monetary stimulus in November, resigned after five years at the central bank. Warsh, 40, a former investment banker who was the youngest-ever Fed governor when President George W. Bush appointed him in 2006, will leave "on or around March 31," he said in a letter to President Obama that was released by the Fed in Washington. His departure may give Bernanke a stronger hand to complete or potentially expand $600 billion in Treasury purchases through June.
