On June 23, the ICBA and The Clearing House published a white paper on virtual currency that (i) defines virtual currency and describes the current regulatory environment; (ii) describes key players in the Bitcoin system; (iii) discusses the application of certain functional and prudential payment system regulations that may be applied to the Bitcoin system and other convertible decentralized virtual currencies; and (iv) evaluates potential regulation of virtual currency, virtual currency investment programs, and exchanges. The paper concludes, among other things, that: (i) credentials used to transact in Bitcoin are functionally similar to prepaid cards and arguably fall within the definition of such cards provided in Regulations E and II; and (ii) the CFPB may determine that cross-border transactions in Bitcoin fall within the scope of the CFPB’s Remittance Transfer Rule, which would require entities facilitating such transfers to comply with the rule’s disclosure, reversibility, and error-resolution requirements. The paper discusses potential safety and soundness oversight for entities in the Bitcoin system. It also suggests that existing regulations intended to protect consumers and market participants in the event of the failure of a securities or commodities exchange may be inapplicable to Bitcoin exchanges, and that alternative means of protecting investors and accountholders—such as disclosure requirements and coordinated state-level registration of exchanges—should be explored.
