BREAKING: The U.S. Department of the Treasury has announced the lifting of certain Iran-related sanctions, according to its official website.
What is the nature of these sanctions, and are they truly being lifted or abolished?
What the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) is doing does not constitute a complete and permanent repeal of sanctions. A full and definitive removal would require legislation passed by the U.S. Congress. Instead, these measures generally involve a temporary suspension or the issuance of waivers and regulatory exemptions as part of broader political understandings.
U.S. policy has often relied on formalizing political understandings on paper to secure immediate strategic interests and navigate pressing crises—such as ensuring freedom of navigation or resolving tensions affecting key maritime chokepoints. Once those objectives have been achieved, however, such commitments have at times been revised, narrowed, or allowed to lapse, leaving the other party facing a reality in which earlier paper-based assurances no longer carry practical effect.
