United States sanctions on Iran are a series of statutory, executive, and regulatory measures imposed by the United States on the Islamic Republic of Iran designed to influence Iranian behavior regarding nuclear proliferation, regional security, and human rights. Initiated after the Iran hostage crisis and expanded through responses to the Iran–Iraq War, Treasury Department designations, and the Joint Comprehensive Plan of Action negotiations, the measures have involved the Department of State, Department of Commerce, Office of Foreign Assets Control, and the U.S. Congress. Sanctions have targeted Iranian institutions such as the Central Bank of Iran, Islamic Revolutionary Guard Corps, and state-owned enterprises, affecting relations among United States–Iran relations, European Union–Iran relations, and United Nations Security Council diplomacy.

Overview and objectives

The policy aimed to constrain Iran’s nuclear program and regional activities by pressuring entities such as the Atomic Energy Organization of Iran and the Islamic Revolutionary Guard Corps while promoting compliance with Non-Proliferation Treaty norms and human rights obligations under instruments like the Universal Declaration of Human Rights and resolutions of the United Nations General Assembly. Objectives included cutting revenues to Iranian actors implicated in support for groups such as Hezbollah, Hamas, and militias involved in the Syrian Civil War, while bolstering leverage for negotiations with counterparts including the European Union External Action Service, the P5+1, and the International Atomic Energy Agency. Sanctions sought to deter procurement networks linked to entities formerly on the Specially Designated Nationals and Blocked Persons List managed by the Office of Foreign Assets Control.

Legal and regulatory framework

Authorities derive from statutes like the International Emergency Economic Powers Act, the Iran Sanctions Act of 1996, the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010, and sections of the Countering America’s Adversaries Through Sanctions Act administered by the U.S. Department of State, U.S. Department of the Treasury, and U.S. Department of Commerce. Executive actions such as Executive Order 12170 and subsequent executive orders invoked powers to block property and prohibit transactions with designated Iranian persons and entities including the Central Bank of Iran and subsidiaries. Regulatory tools include export controls under the Export Administration Regulations and visa restrictions pursuant to statutory authorities applied by the Bureau of Industry and Security and the Directorate of National Intelligence-informed listings.

Chronology of major sanctions packages

Sanctions began after the Iran hostage crisis in 1979, expanded during the Iran–Iraq War, and intensified with the Iran and Libya Sanctions Act of 1996; the Iran Sanctions Act later evolved into the Comprehensive Iran Sanctions, Accountability, and Divestment Act. The United Nations Security Council adopted resolutions in the 2000s that dovetailed with U.S. Treasury measures targeting Iran’s nuclear program and proliferation networks linked to the A.Q. Khan network and procurement channels. After the 2015 Joint Comprehensive Plan of Action was implemented, the European Commission coordinated relief measures, but the 2018 announcement by President Donald Trump to withdraw from the JCPOA led to "maximum pressure" sanctions reinstated via the Office of Foreign Assets Control and secondary sanctions targeting foreign actors such as TotalEnergies, Siemens, and Samsung affiliates. Subsequent legislative and administrative actions under the Biden administration adjusted enforcement priorities while maintaining core prohibitions.

Targeted sectors and measures

Primary measures targeted the energy industry including state-owned firms like the National Iranian Oil Company and the National Iranian Tanker Company, the financial sector through the Central Bank of Iran, and the shipping industry through vessel sanctions and maritime interdiction authorizations. Secondary sanctions discouraged foreign investment by penalizing banks such as those linked to Deutsche Bank or BNP Paribas when engaging with designated Iranian entities; the SWIFT exclusion precedent affected Iranian banking connectivity. Technology controls restricted exports of dual-use goods overseen by the Bureau of Industry and Security, while asset freezes and designation lists managed by the Office of Foreign Assets Control targeted individuals and networks including members of the Islamic Revolutionary Guard Corps and facilitators of procurement for the Aerospace industries.

Economic and humanitarian impact

Sanctions reduced Iran’s oil revenues and foreign exchange access, affecting macroeconomic indicators tracked by the International Monetary Fund and World Bank while contributing to inflationary pressures noted by the Statistical Center of Iran. Humanitarian exemptions for food and medicine were administratively constrained, prompting interventions by NGOs such as International Committee of the Red Cross and debates in forums like the United Nations Human Rights Council regarding secondary effects on healthcare, public health programs overseen by the World Health Organization, and civilian livelihoods. Studies by academic institutions including Harvard University and Georgetown University have assessed sanctions’ distributive impacts and the efficacy of targeted versus comprehensive measures in achieving policy goals.

International coordination and sanctions evasion

Coordination involved partners such as the European Union, Japan, South Korea, and members of the G7, while multilateral mechanisms like the Financial Action Task Force addressed circumvention via shell companies, currency swaps, and informal finance networks such as hawala linked to entities in the United Arab Emirates and China. Iran pursued evasion tactics including use of front companies, ship-to-ship transfers, barter arrangements with entities in Russia and Turkey, and engagement with fintech workarounds; enforcement actions targeted intermediaries in ports like Bandar Abbas and firms in jurisdictions implicated in illicit finance.

Effect on U.S.–Iran relations and diplomacy

Sanctions have been central to U.S. leverage in negotiations culminating in the Joint Comprehensive Plan of Action and subsequent diplomatic exchanges, influencing interactions between administrations including Barack Obama, Donald Trump, and Joe Biden. While sanctions have constrained Iranian capabilities and incentivized talks at times, they have also hardened political positions in Tehran among actors such as the Supreme Leader of Iran, President of Iran, and the Islamic Revolutionary Guard Corps, complicating pathways to sustained diplomatic engagement and arms control outcomes pursued by the International Atomic Energy Agency and multilateral interlocutors.
