On August 24, 2026, the U.S. Department of the Treasury (Treasury) announced “Operation Economic Outcast,” which it described as an unprecedented, whole-of-government economic campaign against the Islamic Republic of Iran and its enablers. Treasury’s Office of Foreign Assets Control (OFAC):
Treasury took additional action on August 28, 2026. Its Financial Crimes Enforcement Network (FinCEN) issued a proposed rule under Section 311 of the USA PATRIOT Act designed to cut off access by Banque Misr UAE to the U.S. and global financial system. Treasury said this action would “cut off a key financial lifeline and sanctions evasion vehicle for the Iranian regime.”
Treasury has stated that officials from the Departments of the Treasury, State and War are pressing counterparts worldwide to shut down Iran-related commercial and financial activity within defined timelines, indicating that if they fail to act, Treasury officials will act unilaterally.
Non-U.S. companies, including financial institutions, with direct or indirect exposure to Iran should reassess their sanctions and anti-money laundering compliance risk in light of the U.S. government’s announced campaign.
OFAC issued five new sectoral sanctions determinations under Executive Order 13902 covering Iran’s digital-asset, technology, gold, aviation and shipping sectors. The order, issued on January 10, 2020, itself targeted the construction, mining, manufacturing and textiles sectors of the Iranian economy, and prior determinations have added Iran’s financial and petroleum and petrochemical sectors. Executive Order 13902 authorizes blocking sanctions against persons operating in a designated sector and persons that materially assist them or engage in significant transactions with them. The order also targets foreign financial institutions that knowingly conduct significant transactions involving a designated sector by authorizing Treasury to restrict their access to U.S. correspondent accounts.
Because U.S. persons are already broadly restricted from transacting with Iran, the primary practical impact of the latest sector determinations falls on non-Iranian, third-country companies and financial institutions with exposure to the newly-designated sectors, such as those transacting with Iranian commercial airlines or digital-asset exchanges.
Given the breadth of existing Iran sanctions authorities, the new sector determinations do not fundamentally expand OFAC’s existing powers. They do, however, allow OFAC to designate any person, regardless of location, who it determines operates in any identified sector without having to establish a separate nexus to sanctioned activity, broadening the pool of potentially sanctionable persons. The principal significance of the new sector determinations is as an enforcement signal: they put third-country companies and financial institutions on notice that the administration considers these sectors near-term enforcement priorities, and that continued engagement with Iranian actors in these areas carries heightened secondary sanctions risk.
The five general licenses OFAC has suspended, effective September 8, 2026, cover educational activities, personal remittances, conference attendance, sports activities and certain academic exchanges and services.
In issuing its proposed regulations targeting Banque Misr UAE, FinCEN found that the five branches of the bank operating in the UAE (collectively, Banque Misr UAE to be of primary money laundering concern under Section 311 of the USA PATRIOT Act).
According to Treasury, Banque Misr UAE processed approximately $1.8 billion for 103 companies that are potentially part of Iranian shadow banking networks between January 2024 and June 2026. Treasury alleges that the bank’s customers include apparent front companies used by Iran’s Ministry of Defense and the IRGC to evade sanctions and to launder money on behalf of Iranian Supreme Leader Mojtaba Khamenei.
The proposed rule would:
This action is designed to sever Banque Misr UAE’s access to the U.S. financial system and to signal to financial institutions worldwide that facilitating Iranian access to U.S. dollar correspondent banking carries severe consequences. FinCEN has used Section 311 authority before to designate or propose measures against institutions connected to North Korean and other illicit-finance networks, many of which ceased operations prior to finalization of the proposed measures. Treasury’s deployment of this tool in an Iran-specific enforcement campaign underscores the seriousness of the current posture and signals to financial institutions worldwide that facilitating Iranian access to the U.S. financial system carries significant risk.
As a result, and in light of FinCEN’s finding that Banque Misr UAE is of primary money laundering concern, U.S. and foreign financial institutions should consider taking measures to address risks that may be presented by transacting with Banque Misr UAE.
The public comment period closes October 1, 2026.
Treasury Secretary Bessent announced at a G20 meeting that the European Union had officially signaled its support for the U.S. campaign, suggesting growing multilateral alignment on Iran enforcement. In contrast, China has condemned the new U.S. sanctions actions, labeling them “illegal unilateral sanctions,” according to state-owned China Global Television Network.
OFAC already has significant authority to impose blocking sanctions on non-U.S. parties for various Iran-related activities, under various statutes and executive orders. It remains to be seen how vigorously OFAC will exercise those authorities, including with respect to larger Chinese companies, such as financial institutions, that engage in certain dealings with Iranian or other designated parties, including the purchase of Iranian oil. Meaningful implementation of the new measures may therefore depend on the administration’s willingness to target larger Chinese entities rather than limiting enforcement to less consequential actors. Given the scale of China-Iran trade — and the fact that China purchases the vast majority of all exported Iranian oil — the scope of that implementation will likely be a critical test of the campaign’s effectiveness.
