Biden appointee Adriana Kugler hasn’t said why she is leaving. Her departure comes at a precarious time for the central bank.

O n Friday, the Federal Reserve announced Adriana D. Kugler, a member of its Board of Governors, is resigning early in a move that will allow President Donald Trump to select her replacement amid ongoing tensions with Jerome Powell, the body's chair.

Her resignation now paves the way for Trump to put his own nominee in for the board. Two of his prior appointments, Christopher Waller and Michelle Bowman, voted against the decision at Wednesday's meeting to hold the Fed's key rate steady, instead indicating they wanted to lower. Kugler was absent for the vote.
