The Office of the Comptroller of the Currency made changes to its large-bank supervision team, which is responsible for examinations and supervisions of the nation's biggest banks. There are 15 lenders that fall under this team's oversight, holding a combined $7.5 trillion in assets, roughly 88% of all national bank assets. Mike Brosnan will become the senior deputy comptroller for large bank supervision at the end of 2010, replacing the retiring Doug Roeder. Brosnan served 21 years at the OCC before leaving in 2004 to spend four years as a senior executive at MBNA Corp. and then Bank of America (BAC) before rejoining the OCC in 2008. Vance Price and Sally Belshaw will join the team as portfolio managers for the large banks as deputy comptrollers for large bank supervision. Grace Dailey will return to the OCC to direct supervision of one of the team's largest banks as examiner-in-charge of US Bank (USB) in Minnesota. "As the supervision of large banks evolves in response to regulatory reform and the changing marketplace, the agency and the industry are fortunate to be able to rely on such talented leaders," acting Comptroller of the Currency John Walsh said.
