Treasury Expands Sanctions Under Economic Fury Campaign

The US Treasury this week imposed sanctions on more than 50 companies, vessels, and individuals connected to Iran’s shadow banking and oil networks. The action forms part of the Trump administration’s Economic Fury campaign, which targets financial structures used by Tehran to move funds despite existing sanctions.

The Office of Foreign Assets Control, or OFAC, designated Iran-based Ebrahimi and Associates Partnership Company, widely known as Amin Exchange. According to the Treasury, the exchange house moved hundreds of millions of dollars on behalf of sanctioned Iranian banks. CEO Samad Nemati, described as a former officer of the Islamic Revolutionary Guard Corps, and owner Yousef Ebrahimi were also designated.

In addition to the main entity, eight associated companies were added to the Specially Designated Nationals list. Treasury officials stated that Amin Exchange operates front companies across the United Arab Emirates, Türkiye, Hong Kong, and China. Counterparties referenced in the action include the National Iranian Oil Company and Triliance Petrochemical, both of which are already under US sanctions.

In a public statement, the Treasury Department said the measures target a prominent Iranian foreign currency exchange house and associated front companies that oversee hundreds of millions of dollars in transactions for sanctioned banks.

Nineteen Tankers and Maritime Operators Added to Sanctions List

The latest measures also focus on Iran’s oil export infrastructure. OFAC blocked 19 oil and petrochemical tankers that have transported millions of barrels of Iranian oil, naphtha, methanol, and liquefied petroleum gas since 2023.

The vessels are linked to owners based in Hong Kong, the Marshall Islands, and Liberia, all of whom were designated as part of the action. By targeting both ships and operators, the Treasury aims to disrupt what it describes as a shadow fleet moving Iranian energy products through international markets.

The designation freezes any US-based assets of the listed parties and generally prohibits US persons from engaging in transactions with them. The move adds to existing restrictions on Iranian oil exports and related financial flows.

Crypto Transactions Identified as Part of Iran’s Financial Workarounds

The Treasury’s announcement places particular emphasis on cryptocurrency. Secretary Scott Bessent stated that the Economic Fury campaign has frozen nearly $500 million in regime-linked cryptocurrency. This figure builds on earlier actions, including a $344 million Tether, or USDT, freeze on the Tron blockchain.

According to Bessent, Iran’s shadow banking system facilitates the illicit transfer of funding for terrorist purposes. He said exchange houses based in Iran move billions in foreign currency each year, enabling Tehran to convert oil revenue and channel funds to its armed forces.

The Treasury has also applied pressure to crypto platforms. The announcement references previous pressure on Binance over Iran-linked financial flows. While no new measures against specific crypto exchanges were detailed in this action, officials signaled that digital assets remain under scrutiny as part of sanctions enforcement.

For crypto users and platforms operating internationally, the development highlights how blockchain-based transactions are being monitored in the context of sanctions compliance. Stablecoins such as USDT were explicitly mentioned in connection with prior freezes.

Warning to Global Banks and Risk of Secondary Sanctions

Secretary Bessent warned global banks to monitor how Tehran continues to move funds through the international financial system. The Treasury signaled that additional secondary sanctions could follow against foreign banks, refineries, and airlines that help process Iranian financial or oil-related flows.

Secondary sanctions can affect non-US entities that conduct business with sanctioned parties, even if they are not based in the United States. The statement indicates that enforcement efforts may extend beyond directly designated Iranian actors to international intermediaries.

The Treasury framed the measures as part of a broader effort to counter Iran’s use of shadow banking structures. Officials described these systems as mechanisms for converting oil revenue and maintaining access to foreign currency despite existing restrictions.

Implications for Crypto and Financial Service Providers

The action underscores the integration of cryptocurrency into broader sanctions enforcement strategies. Nearly $500 million in regime-linked crypto has been frozen under the campaign, according to Treasury figures. The prior $344 million USDT freeze on Tron is cited as an example of how authorities have acted on blockchain-based assets.

For exchanges, payment processors, and financial institutions, the message from US authorities is clear: monitoring of cross-border flows, including digital assets, remains a priority. Entities operating in jurisdictions mentioned in the announcement, such as the UAE, Türkiye, Hong Kong, and China, may face increased scrutiny if linked to designated parties.

At the same time, maritime operators and energy traders connected to Iranian oil shipments are directly affected by the blocking of 19 vessels and the designation of associated owners.

Our Assessment

The US Treasury’s latest action expands sanctions against Iran by targeting more than 50 entities and vessels across financial, maritime, and cryptocurrency channels. The designation of Amin Exchange and associated front companies, along with the blocking of 19 tankers, reflects a coordinated effort to address both oil exports and digital asset flows. Treasury officials confirmed that nearly $500 million in regime-linked cryptocurrency has been frozen under the Economic Fury campaign and signaled that further secondary sanctions against foreign intermediaries remain possible based on ongoing monitoring of Iranian financial activity.
