The Tangled Web of Iran Sanctions

The United Nations sanctions framework, initially established between 2006 and 2010, targets Iran's nuclear and ballistic missile programs. Although the 2015 Joint Comprehensive Plan of Action provided a roadmap for their removal, the U.S. withdrawal from the agreement in 2018 triggered a 'snapback' mechanism that restored these international restrictions. Beyond the U.N., the U.S. maintains a separate, more aggressive regime that began in 1979. These measures, often managed by the Treasury, are rooted in emergency powers and congressional mandates that complicate any rapid reversal. Washington’s designation of the Islamic Revolutionary Guard Corps as a terrorist organization serves as a major hurdle, as the group remains a central pillar of the Iranian economy.

The European Union has mirrored these pressures through targeted embargoes on petrochemicals, precious metals, and financial services. By disconnecting Iranian banks from the SWIFT international payment system, the EU effectively isolated much of the nation's financial infrastructure from global markets. Today, Iran faces the reality of tens of billions of dollars in oil and gas revenue trapped in foreign banks across countries including South Korea, China, and Japan. Even with potential diplomatic breakthroughs, the process of clearing specific entities and individuals from these international blacklists remains a slow, arduous task that defies simple executive action.
