Deep Tide's Guide: On August 24, the U.S. Treasury Department launched "Operation Economic Outcast." OFAC included digital assets within the scope of sanctions on Iran's economic sector under Executive Order 13902, stating that Iran is increasingly using cryptocurrency as a preferred tool for sanctions evasion. The Treasury Department alleges that Emirati-Ukrainian broker Ivan Obukhov has facilitated over $100 million in cryptocurrency payments since 2023, assisting in oil sales for the Islamic Revolutionary Guard Corps' Quds Force (IRGC-QF), and sanctioned him and his company Foscom FZE. Concurrently, nearly 60 entities, individuals, and vessels were added to the sanctions list.
The U.S. Treasury Department announced the launch of "Operation Economic Outcast" on August 24, describing it as a whole-of-government economic campaign targeting the Iranian regime and its supporters. As part of the operation, the Office of Foreign Assets Control (OFAC) issued sectoral sanctions determinations targeting five key sectors—digital assets, technology, gold, aviation, and shipping—under Executive Order 13902.
This determination "significantly expands" OFAC's ability to sanction foreign individuals and companies: they can be sanctioned if they are determined to be operating in or providing supportive services to Iran's digital asset sector, regardless of location. Property of designated persons subject to U.S. jurisdiction will be blocked, and foreign financial institutions that facilitate significant transactions for them may face restrictions on their U.S. correspondent or payable-through accounts.
The Treasury Department stated clearly in its announcement: "The Iranian regime is increasingly turning to cryptocurrency as the tool of choice for sanctions evasion, facilitating transactions linked to the Islamic Revolutionary Guard Corps (IRGC) and Iranian regime insiders."
Over $100 Million in Crypto Payments Allegedly Aid IRGC Oil Sales
In this action, OFAC specifically sanctioned Emirati-Ukrainian broker Ivan Obukhov and his company, Foscom FZE.
According to the Treasury statement, Obukhov has for years served as a broker for vessels in Iran's shadow fleet and facilitated oil shipments for the Iranian military and its proxies. Since 2023, he has processed over $100 million in cryptocurrency payments to facilitate oil sales on behalf of the IRGC-QF. He also coordinated with others to procure vessels later used for sanctions evasion activities. Foscom FZE is a UAE-based company he acquired and serves as the owner and general manager of, in 2022.
Obukhov was designated pursuant to E.O. 13224, as amended, for having materially assisted, sponsored, or provided financial, material, or technological support for, or goods or services to or in support of, the IRGC-QF. Foscom FZE was designated for being owned, controlled, or directed by, or having acted or purported to act for or on behalf of, directly or indirectly, Obukhov.
The Treasury Department concurrently sanctioned nearly 60 entities, individuals, and vessels, covering networks for nuclear and missile procurement, cyber operations, and oil revenue.
Sectoral Sanctions Significantly Move Secondary Sanctions Risk Forward
Unlike previous pinpoint actions against specific exchanges or wallets, this digital asset sector determination establishes a broader sanctions basis. Any foreign person determined to be operating in or providing supportive services to Iran's digital asset sector may be added to the sanctions list.
In a related statement, Treasury Secretary Scott Bessent said: "Today, at the direction of President Trump, the U.S. Treasury Department is launching 'Operation Economic Outcast'... Our goal is to sever every economic lifeline propping up this authoritarian regime until Tehran is left isolated." He likened the operation to an "economic D-Day," emphasizing that the United States is no longer merely "managing" the Iranian threat but seeking to "end" it.
Bessent also warned that any entity engaging economically with the regime will face the full reach of American power.
Previous Series of Enforcement Actions Targeting Iran's Crypto Channels
This sector-level action is the latest escalation in the U.S. ongoing effort to constrict Iran's cryptocurrency channels.
In January 2026, OFAC sanctioned digital asset exchanges linked to Iran for the first time, designating UK-registered Zedcex and Zedxion. In June, the Treasury Department sanctioned four Iranian crypto exchanges, including Iran's largest platform, Nobitex. On August 7, OFAC sanctioned Shelbit and Aban Tether, stating the pair collectively facilitated approximately $5 million in digital asset flows linked to Iran.
Treasury Secretary Bessent previously stated publicly that the U.S. had seized nearly $1 billion in cryptocurrency from Iran-linked exchanges and wallets. Previous enforcement also included blocking actions against specific wallets.
The Treasury Department listed digital assets alongside technology, gold, aviation, and shipping as key areas through which Iran seeks to prop up its economy, stating it has mapped the nodes of the networks Iran uses to smuggle oil, evade sanctions, and fund related activities.
Role of Crypto Payments in Oil Sales and Sanctions Evasion Further Targeted
U.S. officials have characterized cryptocurrency as a critical alternative pathway for Iran after its traditional financial channels were restricted. The Treasury Department noted that digital assets are being used to support transactions linked to the IRGC and regime insiders, and are tied to activities such as the repatriation of oil sales revenue.
The inclusion of the entire digital asset sector under the E.O. 13902 framework means the threshold for future sanctions against foreign intermediaries, exchange service providers, payment channels, and even related technical support providers is further lowered. Designated persons not only face asset blocking risks themselves, but their transaction counterparts may also trigger secondary sanctions considerations.
As of publication, OFAC has already taken designation actions against relevant persons pursuant to the above determination and continues to update the sanctions list.
