The U.S. Department of the Treasury has privately required Binance to comply with the independent monitoring program the exchange agreed to as part of its 2023 guilty plea, after reports that more than $1 billion flowed through the platform to Iran-linked entities in 2024 and 2025. Treasury Under Secretary for Terrorism Gene Lange reminded the company of its obligation to cooperate fully with the monitor — including sharing relevant data records and documents in a timely manner — in a letter sent in recent weeks, according to The Information.
Binance told The Block it is providing the monitor with "full cooperation and transparency," and said it "welcome[s] constructive feedback from the Treasury" while working to "increase transparency and speed up response time." The exchange did not dispute the existence of the letter.
Why it matters
The monitoring program is not a fresh penalty — it is the same three-year independent compliance monitor Binance agreed to retain as part of its 2023 settlement, when the exchange pleaded guilty to charges related to sanctions and anti–money-laundering violations and paid over $4 billion in penalties. Treasury invoking that program now, rather than opening a new case, signals regulators see the existing remediation regime as the appropriate lever — but it also signals they are watching closely.
The pressure comes against a backdrop of armed conflict between Iran and the U.S. and tightening sanctions enforcement, and it follows Democratic inquiries from February and April urging the DOJ and Treasury to investigate whether Binance is still violating U.S. sanctions law. The political backdrop adds weight: President Trump's pardon of former CEO Changpeng Zhao had already drawn ethics concerns, and Sen. Richard Blumenthal specifically asked for more information about the monitors Binance was required to maintain.
Market impact
For Binance, the operational risk is structural rather than financial. Any finding that the company is withholding information from its monitor could reopen the 2023 settlement and re-expose the exchange to fresh DOJ action, additional penalties, or restrictions on U.S. operations.
