Treasury moves to cut Banque Misr UAE off from US correspondent banking

What happened

On 28 August 2026, the U.S. Department of the Treasury announced that its Financial Crimes Enforcement Network (FinCEN) had proposed a rule to revoke Banque Misr UAE’s correspondent banking access to U.S. financial institutions. Treasury placed the action under Operation Economic Outcast. The proposal finds Banque Misr in the United Arab Emirates to be a financial institution operating outside the United States of primary money laundering concern.

The mechanism is section 311 of the USA PATRIOT Act. FinCEN proposes prohibiting U.S. financial institutions from opening or maintaining a correspondent account for, or on behalf of, Banque Misr UAE. The rule would also require U.S. institutions to take reasonable steps not to process a transaction for a correspondent account in the United States of a foreign banking institution where that transaction involves Banque Misr UAE, and to apply special due diligence to their foreign correspondent accounts designed to guard against such use.

Treasury estimates that between January 2024 and June 2026, Banque Misr UAE processed approximately $1.8 billion for 103 companies that are potentially part of Iranian shadow banking networks. Treasury also states that the bank’s customers include apparent front companies used by Iran’s Ministry of Defense and the Islamic Revolutionary Guard Corps to evade U.S. sanctions.

Scope matters here. Treasury says the finding and the accompanying proposed special measure apply only to Banque Misr UAE as defined in the proposal, and not to Banque Misr operations in any other country. The public comment period closes 30 days after the proposal is published on the Federal Register. Treasury announced same day designations alongside it, including the general manager of Bank Melli’s Dubai Branch and a Hong Kong based trading company.

Why it matters

Section 311 is the sharpest correspondent banking instrument the United States has, and the timing creates a gap practitioners have to manage. The proposal is not yet binding. The reputational and de-risking consequences, on the evidence of how the market has treated prior special measures, tend to start on announcement day rather than on the effective date.

Treasury’s own framing points the same way. Its statement says financial institutions around the world face heightened sanctions risk due to their exposure to Banque Misr UAE and other Iranian financial facilitators, which reads less as a description of the proposed rule and more as a warning about counterparty risk that already exists.

The likely effect is a scramble to locate exposure that is not held directly. A named bank is easy to screen. A nested relationship, where a third party bank clears through a correspondent that in turn banks Banque Misr UAE, is not, and that is where the $1.8 billion Treasury describes would have moved.

Practitioner angle

Run the exposure search now, during the comment period, not after a final rule.

• Query payment history and customer records for Banque Misr UAE and its UAE branches by name, by SWIFT BIC, and by branch address, then repeat the query against nested and downstream correspondent relationships.
• Set the lookback to January 2024 to June 2026, matching the period Treasury cites, so any hits align with the conduct described in the proposal.
• Check whether your institution holds a correspondent account for a foreign bank that itself banks Banque Misr UAE. That is the relationship the proposed rule would reach through your special due diligence obligation.
• Refresh customer due diligence on any counterparty among the 103 companies described, if you can identify them, and on trade or exchange house customers with UAE nexus and Iranian ownership indicators.
• Brief the sanctions committee and file the exposure position in writing, with a date, so a later examiner sees the institution acted on the announcement.

Do not wait for the final rule to move the relationship. Decide this quarter whether you are exiting, restricting, or documenting why you are holding it.
