Input: NEW YORK (Reuters) - The Federal Reserve Bank of New York confirmed on Monday that  William Dudley   among the most influential monetary policymakers throughout the financial crisis and its aftermath  expects to retire by mid-2018  raising another question over leadership at the U.S. central bank less than a week after President Donald Trump chose a new Fed chief.

Aside from Yellen and Dudley  only three other current Fed rate-setters were in the room nearly a decade ago when emergency measures were taken to head off the crisis. “ Dudley  was an important source of institutional memory  stability and experience  and that will be tough to replace ” said Eric Winograd  U.S. economist at AllianceBernstein.
As financial watchdog  the New York Fed president has repeatedly criticized poor culture and behavior that led for example to bankers manipulating the Libor reference rate. Yet  Dudley himself  has faced criticism from Congress and others  including for the New York Fed’s failure to stem JPMorgan’s risky so-called London Whale trades in 2012.
