New Sanctions Announcement

On September 23, 2026 the U.S. Department of the Treasury’s Office of Foreign Assets Control released a Federal Register notice announcing additional designations on its Specially Designated Nationals and Blocked Persons List (SDN List)【1】. The notice states that OFAC has identified “one or more persons” whose conduct satisfied one or more applicable legal criteria, triggering their addition to the SDN List【1】. Once listed, all property and interests in property within U.S. jurisdiction belonging to those persons are blocked, effectively freezing any assets they hold under U.S. law【1】. Moreover, the notice clarifies that U.S. persons are generally prohibited from engaging in any transactions with the designated individuals, extending the sanction’s reach to private and corporate actors within the United States【1】.

The SDN List is a core component of the United States’ global sanctions architecture, administered by OFAC under the authority of the Treasury Department【1】. Inclusion on the list does not require a public indictment or disclosure of the specific conduct, only that the statutory or regulatory criteria for designation have been met【1】. The Federal Register serves as the official medium for publishing such sanctions actions, providing legal notice to U.S. persons and foreign entities alike【1】. By issuing the notice, OFAC fulfills its statutory mandate to publicly identify sanctioned individuals, thereby enabling compliance monitoring and enforcement across the U.S. financial system【1】.

Strategic Rationale

The strategic logic of the action rests on the pre‑existing legal framework that empowers OFAC to block assets of persons deemed hostile to U.S. interests【1】. By targeting “one or more persons” rather than entities, the Treasury can apply pressure directly to individuals who may be decision‑makers or financiers behind illicit behavior【1】. The blanket prohibition on U.S. persons from transacting with the designees creates a deterrent effect, signaling that any engagement with the listed individuals will expose American businesses to legal risk【1】. This approach aligns with the broader U.S. policy of using economic levers to isolate actors without resorting to kinetic measures【1】.
