U.S. Senators Question Department of Justice and Treasury Department: Doubts Remain on Binance's Compliance Monitoring Mechanism

On April 17, per a Fortune report, U.S. Senator Richard Blumenthal sent letters to the U.S. Department of Justice (DOJ) and the Financial Crimes Enforcement Network (FinCEN) requesting an update on Binance’s compliance monitoring mechanism—amid concerns over roughly $1.7 billion in Iran-related cryptocurrency transactions. In the letter, Blumenthal noted that market allegations of Binance’s “critically insufficient” anti-money laundering (AML) measures have grown. He asked regulators to disclose the performance of two independent monitors assigned to the exchange. This monitoring stems from a 2023 settlement between Binance and U.S. authorities: Binance paid ~$4.3 billion in fines for compliance failures and agreed to independent oversight, which launched in 2024. Reports recently surfaced that Binance fired internal investigators who had previously alerted executives to over $1 billion in funds flowing to wallets linked to Iran. Binance pushed back, saying the dismissals were unrelated to the investigation and emphasizing the company maintains a strict compliance system. Notably, the senator’s inquiry coincides with the DOJ reportedly reviewing corporate monitorship programs. Earlier, media revealed the DOJ paused some monitoring arrangements—including ending requirements for Glencore and Boeing. To date, Binance’s monitors and relevant regulators have not publicly responded to the inquiry.
