There are reports this morning that Ben Bernanke wont stand for re-appointment as chairman of the Fed even if Obama wins re-election. Considering that only a month ago he pushed to extend QE indefinitely, leaving now seems equivalent to changing pilots mid flight. Still, Bernanke has been chair for 6 years. How does this compare to the term length of other chairmen?
At a little under 19 years, William McChesney Martin held the post for the longest period, which Alan Greenspan nearly matched. Eugene Black had the shortest term at 15 months. The average term length is ~7 years.
