U.S. plans to sanction large bank over Iran, according to remarks by Treasury Secretary Scott Bessent reported by Reuters. Bessent said the administration planned to sanction an unnamed large bank on Monday, September 14, as part of its pressure campaign against Iran. At the time of TPS’s review, the bank’s identity, country and final Treasury or OFAC sanctions instrument had not been established.
Current status: a large-bank sanction has been publicly signalled, but TPS has not verified a completed Treasury or OFAC designation for the unnamed institution. The safe current description is therefore planned sanction, not bank already sanctioned.
What has the U.S. announced so far?
Reuters reported that Bessent said the Trump administration would sanction a large bank on Monday as part of its economic pressure campaign against Iran. The reported remarks did not identify the institution or its country.
The announcement matters because it moves the Iran financial-pressure campaign from a general policy direction to a specific near-term bank action. But it does not yet establish the target or the legal mechanism Treasury will use.
Has the bank already been sanctioned?
Not in the evidence TPS reviewed. No completed Treasury or OFAC designation naming the bank was recovered at the time of this article’s preparation.
That distinction is important. A Treasury Secretary saying an action is planned creates a credible current information state, but a completed OFAC designation is a later regulatory state with its own legal text, scope, effective timing and possible licenses or restrictions.
Which bank is the U.S. planning to sanction?
The bank remains unnamed in the reviewed reporting. Bessent’s reported remarks also did not establish the institution’s country.
TPS is therefore not identifying or speculating about a target. Earlier Iran-related Treasury actions against other financial institutions do not prove that any one of those institutions is the bank Bessent was referring to.
What kind of sanction could Treasury use?
That is also unresolved. U.S. financial authorities have several tools that can affect foreign banks differently. Depending on the legal instrument, consequences can include blocking sanctions, restrictions involving U.S. correspondent or payable-through accounts, transaction prohibitions, licensing conditions or other measures.
The final Treasury or OFAC notice must be read before assigning any of those consequences to the unnamed bank. TPS is not assuming that the future action will automatically be a full blocking designation.
Why is this linked to Iran?
Bessent’s reported remarks framed the planned bank action as part of the administration’s continuing economic pressure on Tehran. Treasury has separately published multiple recent actions under its Iran-focused pressure campaign, including measures targeting financial, aviation and proxy-linked networks.
That wider campaign confirms the policy context, but it does not reveal the identity of the bank expected to be named in this specific action.
Does this mean U.S. banks must immediately stop dealing with the unnamed bank?
No such conclusion can responsibly be made before the final instrument is available. The compliance consequence depends on which bank is named, the authority Treasury invokes, whether OFAC adds it to a blocking list or uses another mechanism, the effective timing and whether licenses or wind-down provisions apply.
Banks, businesses and payment counterparties should therefore use the controlling Treasury or OFAC notice once it is issued rather than act on speculation about the unnamed institution.
Is this the same as earlier action involving Banque Misr UAE?
No evidence reviewed by TPS establishes that. Treasury had already taken a separate bank-related action involving Banque Misr UAE in August, but that prior action should not be used to guess the identity of the bank Bessent said would face a Monday sanction.
What happens when Treasury names the bank?
The next material state transition is the publication of the bank’s identity and the controlling sanctions instrument. That document should establish the target, legal authority, scope, effective timing and any licenses or restrictions.
This article should then be updated on the same URL. The reader job does not change simply because the target moves from unnamed to named; the current question remains what the U.S. bank sanction is, what state it is in and what practical consequences follow.
What remains unknown
- The identity and country of the bank.
- The exact Treasury or OFAC legal authority.
- Whether the action will be a blocking designation, correspondent-banking restriction or another measure.
- The effective time and any licenses or wind-down provisions.
- The bank’s response.
- Any coordinated action by allied regulators.
- The actual impact on correspondent banking, payments and counterparties.
Verification note
TPS reviewed Reuters reporting of Bessent’s statement and current U.S. Treasury material establishing the broader Iran sanctions campaign. A completed Treasury or OFAC designation for the unnamed bank had not been recovered at the final source check, so the article preserves the action as planned and the bank identity and legal instrument as unresolved.
