Fed Nominations Leave Questions Over Regulation

WASHINGTON—President Biden’s decision to reappoint Jerome Powell as Federal Reserve chairman and elevate governor Lael Brainard signals continuity on monetary policy but leaves open questions on the direction the central bank will take in regulating Wall Street.

The extent to which the Fed will spend the next several years tightening regulatory policy—after easing rules under Trump-appointed officials—will depend on whom Mr. Biden ultimately picks to succeed Randal Quarles, the departing central bank governor who served as its regulatory point man until last month.
