Mr. Warsh is a former Fed Governor whose 2006-2011 tenure overlapped with the 2008 financial panic and recession. He has also worked on Wall Street and in the White House under George W. Bush. Though he wasn’t in charge of the Fed at the time, Mr. Warsh’s experience in a crisis will be invaluable when the next one arrives, as it inevitably will. He has deep knowledge of global financial markets, and knows most of the global players—from Europe, to the U.K., Japan and China.
