Final decisions are not imminent in the efforts to find successors to Philadelphia Fed President Charles Plosser, who steps down March 1, and Richard Fisher of the Dallas Fed, who retires on March 19. Matthew Rutherford, whose stint as Treasury’s top domestic finance official ended on Friday, was under consideration at least in early stages of the searches, according to three sources. James McAndrews, who heads up research at the neighboring New York Fed, was considered for the job in Philadelphia, where he once worked.
