The Federal Reserve should begin to withdraw monetary support soon after the pandemic is over, a moment that could set off robust economic growth, Dallas Fed Bank President Robert Kaplan said. The central bank should start by reducing the scale of its asset purchases from the current pace of $120 billion a month, Kaplan said, though he stopped short of saying that the purchases must end completely before the Fed lifts interest rates. “My thought is the tapering would come first,” Kaplan said. “I think in my mind it would be substantially completed before you dealt with Fed funds rate, but I would like to retain flexibility on that.” The Fed’s support should remain in place until the pandemic is over, adding that the crisis could lead to economic scarring and that some people will need help returning to work. Fed officials agreed last month to keep interest rates near zero and to keep purchasing $120 billion a month in bonds until “substantial further progress” is made toward the Fed’s goals for inflation and maximum employment.
