The European Union (EU) has restored wide-ranging sanctions on Iran, following the reactivation of the United Nations (UN) “snapback” mechanism yesterday. The decision brings back measures lifted under the 2015 nuclear deal after France, Germany, and the United Kingdom declared Iran in breach of its commitments.

The EU said it agreed: “to reimpose a number of restrictive measures in relation to Iran’s nuclear proliferation activities, that had then been suspended with the entry into force of the Joint Plan of Action in 2015.” The sanctions now cover travel bans, asset freezes, and restrictions on trade, finance, and transport.

Key measures include a ban on the “imports purchase and transport of crude oil, natural gas, petrochemical and petroleum products and related services.” The EU also confirmed it is “reimposing the freezing of assets of the Central Bank of Iran and of major Iranian commercial banks.” In the transport sector, the EU stated that it is “reinstating measures to prevent access to EU airports of Iranian cargo flights, and to prohibit the maintenance and service of Iranian cargo aircraft or vessels carrying prohibited materials or goods.”

The move will tighten pressure on Iran’s economy. Oil exports, already reduced by American sanctions, will face fresh obstacles in reaching buyers who rely on European shipping and insurance. Banking sanctions will restrict access to payment systems, and aviation bans will add further barriers to trade.

European officials said the measures are designed to respond to nuclear non-compliance while keeping diplomatic channels open. Iran has condemned the decision and recalled some of its ambassadors from European nations.
