Treasury Secretary Scott Bessent has declared an "economic D-Day" against Iran, aiming to sever its financial connections globally and end nearly six months of war. This campaign, dubbed "Operation Economic Outcast" by the U.S. Department of the Treasury, was launched at President Trump's direction and is described as an "unprecedented, whole-of-government, economic campaign" against Iran and its enablers. Bessent stated that the objective is to "sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone," and that President Trump is calling world leaders with "specific requests to cease their interactions with the regime."
The U.S. government is giving countries specific timelines to shut down their links with Iran, warning of unilateral U.S. punishment for non-compliance. Treasury, State, and War Departments are engaging counterparts worldwide to convey these expectations. The campaign will also expand secondary sanctions exposure for those continuing business with the Iranian regime and accelerate U.S. enforcement. Treasury has already identified and is targeting networks, facilitators, and financial channels used by Iran to smuggle oil, evade sanctions, and fund terror, focusing on five critical sectors: digital assets, technology, gold, aviation, and shipping.
In conjunction with this initiative, the Office of Foreign Assets Control (OFAC) sanctioned nearly 60 entities, individuals, and vessels across multiple jurisdictions. These include those involved in illicit nuclear and missile technology procurement, cyber operations, and oil-revenue generation networks. OFAC also suspended general licenses that authorized certain remittance payments to Iran and Iranian access to the U.S. cultural and academic system. The U.S. has been running a naval blockade on Iranian ports to prevent oil exports and has targeted companies, brokers, and tankers helping Iran sell oil abroad.
Key targets include Iran's shadow fleet and oil revenue facilitators. For example, UAE-based Syrian national Mohammad Ahmed Suhil Fattouh, also known as "Captain Hamzah," and UAE-based Ukrainian national Ivan Obukhov have been sanctioned for brokering Iranian shadow fleet vessels and facilitating oil sales for the IRGC-QF. Obukhov, through his company Foscom FZE, has processed over $100 million worth of cryptocurrency payments for oil sales since 2023. Specific vessels sanctioned for transporting Iranian crude oil and petroleum products include the Botswana-flagged LPG tanker SIFRA, Cameroon-flagged LPG tanker G SILVER, Vanuatu-flagged crude oil tanker QUANTUM HOPE, Gambia-flagged crude oil tanker VOYAGE ELITE, and Gambia-flagged TELA.
However, the effectiveness of this campaign faces challenges, particularly with China, which is Iran’s biggest trading partner and leading oil buyer. China purchased 80% of Iran's shipped oil in 2025. While Bessent announced the "economic onslaught," specifics on how the Trump administration would target China were notably absent. This raises doubts about the campaign's overall efficacy, as the U.S. must balance pressuring Iran with avoiding increased tensions with China that could negatively impact the American economy. Beijing has stated that its cooperation with Iran is "within the framework of international law." Evidence of ship-to-ship transfers off the coast of Malaysia also indicates ongoing Iranian oil trade, highlighting evasion tactics.
