FinCEN proposes to amend the regulations issued under 31 U.S.C. 5316, namely the definition of "monetary instrument" at 31 CFR 1010.100(dd) and the international transport of currency and monetary instrument reporting requirement at 31 CFR 1010.340, to include tangible prepaid access devices. The current regulations require that a form be filed reporting the international transportation, mail, or shipment of currency or other monetary instruments in an aggregate amount that exceeds $10,000. The term "monetary instrument" is defined in the BSA to include currency and a variety of bearer negotiable instruments, securities, and similar items, but does not specifically include any types of prepaid access devices. Nevertheless, FinCEN has regulatory authority to expand the definition of monetary instruments to include items deemed to be "similar materials" to coins and currency of a foreign country, travelers' checks, bearer negotiable instruments, bearer investment securities, bearer securities, and stock on which title is passed on delivery.
