On May 19, the Senate Banking Committee’s chairman and ranking member, Senators Tim Johnson (D-SD) and Mike Crapo (R-ID), sent a letter to the leaders of the Treasury Department, the SEC, the CFTC, the OCC, the FDIC, and the Federal Reserve Board regarding recent developments in the use of virtual currencies and their interaction with the global payment system. The Senators ask the regulators a series of questions related to the role of virtual currencies in the U.S. banking system, payment system, and trading markets, and the current role of federal regulators in developing local, national, and international enforcement policies related to virtual currencies. The Senators also seek the agencies’ expectations on virtual currency firms’ BSA compliance, and ask whether an enhanced regulatory framework for virtual currencies is needed.
