Washington claims it has gained a new ally in its financial campaign against Tehran.
On Friday, US Treasury Secretary Scott Bessent stated that the EU had ‘officially joined’ Operation Economic Outcast, the US-led sanctions initiative aimed at cutting Iran off from the global banking system, and praised the bloc for acting swiftly.
However, the European Commission statement he referenced, issued on Monday, welcomed the US initiative without formally binding the EU to it.
“We appreciate their strong and early stance,” Bessent wrote, presenting the move as evidence that global pressure on Iran is increasing.
Bessent added that the international community is ‘sending a clear message to the Iranian regime’ and that Washington ‘will not cease until every remaining financial lifeline to Iran is cut,’ emphasizing that the US ‘stands firm with allies to prevent the murderous Iranian regime from abusing the global financial system.’
What Brussels actually wrote
The document cited by Bessent was published on August 31, the first day of the G20 finance ministers and central bank governors’ meeting in Asheville, North Carolina.
As the current chair of the G20, the United States hosted the summit, with Bessent co‑chairing alongside Federal Reserve Chair Kevin Warsh, and used the forum to urge other nations to sever financial links with Tehran or face possible secondary sanctions.
The EU statement begins by outlining the bloc’s longstanding concerns: Iran’s nuclear and ballistic‑missile programs, its destabilizing actions in the region and Europe, its military backing for Russia’s invasion of Ukraine, and the repression of the Iranian populace.
It notes that the EU ‘has adopted extensive sanctions to prevent Iran from exploiting the global economy and financial system’ and ‘remains prepared to take additional steps, if needed, to protect its security and interests, including ensuring freedom of navigation through the Strait of Hormuz.’
Regarding the US sanctions campaign, the EU’s language is deliberately cautious.
The EU ‘welcomes efforts to make Iran halt its destabilizing activities and engage in peace talks in good faith, including through added economic pressure such as the US‑led Operation Economic Outcast,’ and says it will ‘continue to cooperate closely with the United States and other G7 and international partners.’
The statement does not declare EU membership in the operation; Brussels announced no new sanctions, no alignment with US designations, and no alteration to its existing regime, which already addresses Iran’s nuclear and missile programs and its support for Moscow.
It also reiterated a stance that Washington does not emphasize equally, stating that it ‘believes continued diplomatic efforts are necessary to achieve a peace settlement.’
Endorsement, not accession
The characterization of the EU as having formally joined Operation Economic Outcast originates with Bessent, and several news outlets have echoed his framing.
As of this writing, neither the European Commission nor the European External Action Service has publicly responded to that characterization. To date, Brussels has merely endorsed the US pressure campaign rather than joined it.
This distinction is important because of what Operation Economic Outcast entails.
Launched in late August, the initiative seeks to restrict Iran’s access to digital assets, advanced technology, gold, commercial aviation, and shipping, and depends on secondary sanctions—penalties imposed on foreign companies and banks that continue to do business with Iran.
The US Treasury initially sanctioned nearly 60 companies, individuals, and vessels, and has announced additional measures each week, beginning with banks.
European firms could fall under those penalties, and the EU’s Blocking Statute, in principle, prohibits them from complying with US sanctions on Iran without prior approval from the European Commission.
Currently, the discrepancy between Washington’s claim that Europe has joined the effort and what Europe has actually announced persists. For European banks and exporters, the gap between merely endorsing the campaign and formally participating is the difference between observing the sanctions and being legally bound by them.
