Treasury Secretary Scott Bessent said Thursday that the European Union has officially joined Operation Economic Outcast, the U.S.-led sanctions campaign aimed at economically isolating the country, though the EU’s own statement stopped short of explicitly confirming that characterization.
Bessent posted on X that the United States stands firm with allies in ensuring the government in Tehran cannot exploit the global financial system to fund what he described as its nuclear ambitions, weapons programs and terror proxies.
He shared an Aug. 31 statement from the European Commission, the EU’s executive arm, in which the bloc said it welcomes efforts to ensure Iran ceases its destabilizing activities and engages in peace negotiations in good faith, including through additional economic pressure and through Operation Economic Outcast. The statement added that the EU will continue working closely with the United States and other G7 and international partners to maintain pressure and contribute to de-escalation and regional stability. The EU also said it has already imposed various measures on Iran and is willing to take further action to safeguard its interests.
The EU’s language welcomed the operation and expressed continued coordinated pressure but did not use the phrase officially joining, leaving some ambiguity about the precise nature of the alignment Bessent described.
The context of Operation Economic Outcast
Operation Economic Outcast was announced by the Treasury Department in late August as the formal name for the administration’s Iran sanctions escalation campaign, which has been coordinated with the ongoing military conflict in the Strait of Hormuz and the blockade that has been in place since February.
The campaign is designed to close financial pathways through which Iran can fund its military operations, oil exports and the proxy networks it has used across the region. Previous U.S. administrations have coordinated with European allies on these sanctions, most notably through the 2015 Joint Comprehensive Plan of Action negotiations and subsequent relief, though that agreement broke down after the Trump administration’s withdrawal in 2018.
The EU’s position
The European Union has maintained its own sanctions regime independently of the United States and has historically been reluctant to formally subordinate European foreign policy to American-led operations. The distinction between coordinating with an operation and formally joining it has significance for EU member states that have commercial relationships with Iran or that maintain independent diplomatic channels.
Bessent’s characterization may reflect a U.S. government interpretation of the EU’s coordination commitments rather than a formal EU declaration of membership in the operation.
What it means for Iran
European financial institutions participating in the global dollar-clearing system are already subject to secondary-sanctions risk under U.S. law. If the EU is now explicitly coordinating its own autonomous sanctions actions with Operation Economic Outcast, the combined effect would significantly narrow the country’s options for international financial transactions, even outside the dollar system.
The conflict recently passed the six-month mark, and the trajectory has been toward escalation rather than negotiation.
