If a transaction is underway at the time of an Executive Order 13608-listing, a U.S. person must cease dealing with the listed person and the U.S. person is prohibited from engaging in transactions or dealings in or related to any goods, services, or technology to or from the listed person, unless the transaction is exempt under the International Emergency Economic Powers Act, or until such time that OFAC authorizes the transactions pursuant to the Executive Order 13608. Additionally, if the transaction underway involves a wire transfer, a U.S. financial institution must reject it and file a report with OFAC within 10 days.
Like all of its programs, OFAC has the authority under Executive Order 13608 to license transactions that are consistent with U.S. foreign policy.
