U.S. inflation should rebound next year as pressures related to the strong dollar and low energy prices fade, the Federal Reserve's second-in-command said on Thursday, adding the economy has done well reasonably well thanks in part to a delay in interest rate hikes.

Fed Vice Chairman Stanley Fischer, reinforcing previously stated confidence that more inflation was around the corner, said he expects the central bank's preferred measure to rebound to 1.5 percent next year and to hit a 2 percent goal in the "medium term."
