The ranking member of the U.S. Senate Committee on Banking, Housing and Urban Affairs, Sen. Elizabeth Warren, urged the Office of the Comptroller of the Currency to revoke its approval for United Texas Bank to convert from a Texas state-chartered bank to a national bank. In a letter to Federal Reserve Vice Chair for Supervision Michelle Bowman and Comptroller of the Currency Jonathan Gould, Warren argued that the conversion weakens safeguards against regulatory arbitrage and could encourage other banks to change charters to obtain less stringent oversight. United Texas Bank had been supervised by the Federal Reserve Board and the Texas Department of Banking and was subject to a cease-and-desist order over deficiencies in its anti-money laundering and terrorist financing controls. Warren questioned the OCC’s approval and the Federal Reserve’s failure to object, and requested written responses from Bowman and Gould to support the committee ranking member’s oversight of the decision.
