Ben Shalom Bernanke (English pronunciation: /bərˈnæŋki/ bər-nang-kee; born 1953) is an American economist, and the current Chairman of the Federal Reserve, the central bank of the United States. During his tenure as Chairman, Bernanke has overseen the response of the Federal Reserve to late-2000s financial crisis.

From 2002 until 2005, he served as a member of the Board of Governors of the Federal Reserve System. Here he outlined the Bernanke Doctrine and first spoke of the Great Moderation, where he postulated that we are in a new era, where modern macroeconomic policy has decreased the volatility of the business cycle. He then served as Chairman of President George W. Bush's Council of Economic Advisers before President Bush appointed him to be Chairman of the United States Federal Reserve on February 1, 2006. Bernanke was confirmed for a second term as Chairman on January 28, 2010, after being nominated by President Barack Obama.
