European Union Imposes First Sanctions on Iran's IRGC Navy Over Strait Obstruction

EU foreign policy chief Kaja Kallas said the sanctions were “the first time the EU has applied its new freedom of navigation regime and when necessary we will apply it again.”
Kallas made the announcement during an informal meeting of EU defense ministers in Greek Cyprus, linking the sanctions to the bloc’s wider maritime-security posture.
The reporting described the Strait of Hormuz as a vital chokepoint for energy trade, noting it normally carries “roughly one-fifth of global oil supplies.”
The European Council said the new sanctions build on its March support for a UN Security Council resolution stressing “maritime security” and respect for freedom of navigation through international waters.
The European Union hit Iran's Islamic Revolutionary Guard Corps Navy with its first-ever freedom-of-navigation sanctions on Monday, targeting the IRGC's Hormozgan Provincial Command and two officials accused of choking off the Strait of Hormuz Euractiv. EU foreign policy chief Kaja Kallas called it a historic step, saying: "This is the first time the EU has applied its new freedom of navigation regime and when necessary we will apply it again" Maritime Executive.
The strait is a vital chokepoint that normally carries roughly one-fifth of global oil and LNG supplies. Since Iran began blocking and screening vessels in February 2026, global energy prices have surged more than 50% gCaptain. Monday's sanctions — asset freezes and travel bans — mark the EU's clearest signal yet that it will use financial tools to force the waterway back open.
The crisis traces back to February 28, 2026, when U.S.-Israeli airstrikes hit Iranian military infrastructure and Iran retaliated by closing the Strait of Hormuz i24 News. On May 5, Iran formalized its grip by creating the Persian Gulf Strait Authority (PGSA). Ships must now submit cargo manifests, crew lists, and IMO numbers to the PGSA 72 to 96 hours before transit Newsmax.
Iran calls this a fee for "environmental and security services." The EU and U.S. disagree sharply. They say it violates the UN Convention on the Law of the Sea, which bans countries from charging for transit through international straits Euractiv. The EU now counts 53 Iranian individuals and entities on its navigation-related sanctions list Maritime Executive.
The EU targeted three actors. First, the Hormozgan Provincial Command of the IRGC Navy, which the EU says physically controls shipping movements in the strait. Second, Mohammad Akbarzadeh, an IRGC Navy official accused of threatening commercial vessels with "missiles or drones" if they skip PGSA checks Newsmax. Third, Hamid Hosseini, an oil exporters' union official who promoted the toll system as a condition for safe passage i24 News.
The EU's legal basis was built on March 11, when UN Security Council Resolution 2817 — co-sponsored by 136 countries, including all 27 EU states — condemned Iran's blockade Maritime Executive. The European Council then expanded its Iran sanctions framework on May 22 to explicitly cover threats to freedom of navigation Euractiv.
Monday's EU action aligns closely with the U.S. Treasury's "Economic Fury" campaign. On May 27, Washington designated the PGSA as an IRGC front and called the toll system "maritime extortion" Newsmax. Any shipping company that pays the PGSA now faces strict liability risk under U.S. sanctions law, and international insurers have added clauses to their policies barring payments to IRGC-linked bodies.
Iran's Deputy Foreign Minister Kazem Gharibabadi dismissed the EU move as "political and hypocritical" and accused Europe of ignoring what he called a U.S. naval blockade against Iran i24 News. State media framed the PGSA as a legitimate body similar to the Suez Canal Authority, providing navigational and environmental services in what it calls sovereign waters Euractiv.
Kallas announced the sanctions during an informal EU defense ministers' meeting in Nicosia, Cyprus Maritime Executive. European nations are already preparing a potential mine-clearing operation in the strait. A 15-country coalition is operationally ready but will not deploy until a formal U.S.-Iran agreement creates a safe environment, according to Euractiv.
The G7 summit in Evian, France, set for June 15 to 17, is expected to be the next flashpoint. Leaders will seek President Trump's sign-off on the mine-clearing mission i24 News. The economic stakes are severe: the strait's blockade has cut urea exports by 30%, raising fertilizer costs for European farmers, and analysts warn oil could hit $150 to $200 per barrel if the waterway stays closed Newsmax.
