The National Futures Association reminded futures commission merchants and introducing brokers to comply with the US Department of Treasury’s Office of Foreign Asset Control’s recent guidance for virtual currency transactions. Recently, OFAC addressed virtual currencies in its Frequently Asked Questions and said that persons that identify digital currency identifiers or addresses associated with prohibited persons on blockchains "should take the necessary steps to block the relevant digital currency and file a report with OFAC that includes information about the wallet or address's ownership, and any other relevant details.” (Click here for further details in the article “OFAC Warns Prohibited Persons Using Virtual Currencies Are Still Prohibited Persons” in the March 25, 2018 edition of Bridging the Week.) Separately, CFTC Commissioner Rostin Behnam indicated during a speech before the 40th annual FIA Law and Compliance conference held last week that NFA staff had proposed an interpretive notice to enhance disclosure requirements for members trading underlying/spot virtual currencies and virtual currency derivatives.
