On October 18, the Department of the Treasury released a statement on reaching the formal “Adoption Day” of the Joint Comprehensive Plan of Action (JCPOA), the plan reached between the P5+1, the European Union, and Iran regarding Iran’s nuclear program. Adoption Day is the day JCPOA participants will begin taking steps necessary to implement their JCPOA commitments. According to Treasury Secretary Lew, October 18 marks an “important milestone” as “Iran begins taking its nuclear-related measures and the United States and [its] partners prepare to lift nuclear-related sanctions in response.” Although this action means that the JCPOA’s effective date is October 18, 2015, no sanctions will be lifted until Implementation Day, which will occur after international inspectors confirm that Iran has met its commitments under the JCPOA. As decided in July and outlined in an OFAC press release, licenses with certain credentials will remain in effect in accordance with their terms until Implementation Day. OFAC also issued FAQs concerning Adoption Day. Commenting on the implications of Adoption Day, the White House likewise issued a Statement that it had directed the heads of all relevant executive departments and agencies of the United States to begin preparations to implement U.S. commitments under the JCPOA.
