The Expansive Sanctions Regime Encircling Iran
By Drooid · · How we work
Current Sanctions Regime on Iran
Iran is subject to overlapping sanctions imposed by the United Nations, the United States, the European Union, the United Kingdom and a group of other nations. The United Nations re-imposed sanctions in September 2025 under the “snapback” mechanism of UN Security Council Resolution 2231, reinstating six earlier resolutions that ban arms transfers, restrict nuclear-related materials, limit ballistic-missile activities, freeze assets and target individuals linked to prohibited programmes.
Historical Sanctions Context
Sanctions have been layered on Iran since the 1979 revolution, with successive regimes re-imposed or expanded at various times. Over the decades, restrictions have targeted oil exports, the banking sector, nuclear and missile development, military activities and senior officials.
Sanctions by Major Actors
- United States – The Treasury’s Office of Foreign Assets Control (OFAC) issued a new package that includes a broad trade embargo, secondary sanctions on foreign entities dealing with Iran in sectors such as digital assets, technology, gold, aviation and shipping, and sector-specific measures aimed at energy and shipping.
- European Union – EU measures comprise a nuclear-related embargo on goods and technology, a trade embargo on Iranian oil and petroleum products, bans on dual-use items, financial prohibitions on banks linked to proliferation or terrorism, sectoral restrictions on shipping, aviation, petrochemicals, aluminium and steel, and an arms embargo.
- United Kingdom – The UK mirrors UN and EU restrictions, adding asset freezes on Iranian banks, bans on financial services to entities tied to nuclear or “terrorism” programmes, and human-rights-related sanctions that include travel bans and asset freezes for individuals involved in repression or censorship.
- Other Countries – Australia, Canada, Japan, New Zealand, Norway and Switzerland have adopted comparable sanctions, primarily focused on Iran’s nuclear programme and human-rights violations.
Economic and Human-Rights Impact
U.S. sanctions have frozen billions of dollars in Iranian assets held in U.S. banks, constraining Iran’s access to the international financial system. Combined UN, EU, UK and allied measures limit Iran’s ability to export oil, obtain dual-use technology and engage in international trade, while targeted sanctions aim at individuals and entities linked to human-rights abuses and the Islamic Revolutionary Guard Corps (IRGC).
International Coordination
The sanctions regime reflects a coordinated effort among major powers and multilateral bodies to pressure Iran over its nuclear and missile activities, as well as alleged support for terrorism and human-rights violations. The breadth of the measures underscores the extent to which Iran is one of the most heavily sanctioned states globally.
