There could be four or five more in the next two years.
Fed Chair Janet Yellen four-year ends on February 3, 2018. The same date is when Stanley Fischer's vice-chairmanship ends. It is unlikely, but technically, Yellen can stay on the Board as non-chair until January 31, 2024, after her chairmanship ends.
The same is true for Vice Chair Stanley Fischer. His board term technically lasts after his vice-chairmanship until January 31, 2020. It is unlikley he will stay. So 2018 is the big year for the Fed board with both Yellen and Fischer leaving leadership positions that Trump will have to fill.
Beyond that the other three serving Board of Governors members are Daniel Tarullo, whose term does not end until January 31, 2022; Jerome Powell, whose term isn’t over until January 31, 2028; and Lael Brainard, whose term ends on January 31, 2026.
But John Mauldin at Forbes says they may leave early.
Brainard wants to leave says Mauldin, so does Tarullo.
Of Governor Powell, he writes:
Jerome Powell’s background is impressive, but I wonder if he would want to be the last man standing of the current governors. I have heard nothing either way, and no one seems to really know—other than Governor Powell.So, it’s possible, according to Mauldin, that Trump gets at least six and maybe seven appointments to the Board of Governors of the Federal Reserve within his first two years.
Since Trump does not appear to have any anchor to his economic thinking, its anyone's guess as to who will fill the various vacancies, though unfortunately, I do not expect Ron Paul, Joe Salerno por Murray Sabrin to be among Trump's picks.
