By Aaron Nicodemus2021-05-07T15:49:00+01:00 U.S. Treasury Secretary Janet Yellen appointed Michael Hsu, currently a regulator at the Federal Reserve, to the role of acting comptroller of the currency. Hsu’s official title at the Office of the Comptroller of the Currency (OCC) will be first deputy comptroller, but Yellen said Friday in her announcement that he will also serve as acting comptroller, effective Monday. “Mike has devoted his career to the stability and supervision of America’s banking system. He is among the most talented and principled regulatory officials that I have had the pleasure of working with, and I am confident he will execute this role with integrity and efficiency,” Yellen said.
