Trump Signals Economic Penalties on Iran Trading Partners

A presidential statement without specified mechanisms creates policy uncertainty for US allies and adversaries who conduct commerce with Iran, and the legal and executive tools available to...

President Donald Trump stated on or around August 20, 2026, that the United States would impose economic penalties on countries that conduct business with Iran, according to reporting by The New York Times. The president did not specify which statutory authority, executive order, or regulatory mechanism would be used to carry out such penalties, leaving the precise scope of the threat undefined as of the date of this report.

The United States currently maintains a layered Iran sanctions framework administered primarily by the Treasury Department's Office of Foreign Assets Control (OFAC) and the State Department. Existing legal authorities include the Iran Sanctions Act, the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010, and executive orders including E.O. 13846, which reimposed sanctions following the 2018 U.S. withdrawal from the Joint Comprehensive Plan of Action. These authorities already permit secondary sanctions on foreign entities that conduct certain transactions with Iran.

Secondary sanctions targeting third-country firms and governments have previously been applied to entities in China, India, Turkey, and the European Union, among others. The extent to which a new presidential action would expand, modify, or simply restate existing policy is not determinable from the public statement as reported. No executive order, Federal Register notice, or OFAC guidance had been published as of this writing to clarify the administration's intended action.

Congress retains authority to expand or restrict the Iran sanctions framework through legislation. The Senate Foreign Relations Committee and House Foreign Affairs Committee hold jurisdiction over such measures. No new Iran sanctions legislation had been introduced or scheduled for markup in either chamber as of August 20, 2026, according to the congressional record maintained at Congress.gov.

What remains unknown is the specific legal vehicle the administration intends to use, the list of targeted countries or entities, and the timeline for any action. A formal executive order, a new OFAC designation list, or a State Department determination under existing statute would each constitute the public record that would answer those questions.
