Senator Richard Blumenthal (D-Conn.) has pressed the Department of Justice (DOJ) and the Treasury Department's Financial Crimes Enforcement Network (FinCEN) for updates on the status of monitors assigned to oversee Binance, the world's largest cryptocurrency exchange. This follows reports of $1.7 billion in crypto flows linked to Iran, raising concerns about Binance's compliance with U.S. anti-money laundering (AML) laws and sanctions enforcement.
Mounting Concerns Over Binance Compliance
In letters sent to the DOJ and FinCEN, Blumenthal expressed concern over 'dangerously lax' AML prevention by Binance. The exchange, which agreed to a $4.3 billion settlement with U.S. authorities in 2023 for compliance failures, was assigned two monitors to ensure it overhauled its AML and sanctions oversight programs. These monitorships, managed separately by the DOJ and FinCEN, began in 2024 but have faced scrutiny amid allegations of inadequate enforcement.
'I am writing with concern over mounting allegations of dangerously lax anti-money laundering prevention by Binance,' Blumenthal wrote.
Recent Developments and Iranian Crypto Flows
The Senator's inquiry comes after reports that Binance terminated internal investigators who had flagged over $1 billion in crypto transactions linked to Iran. Binance claims the firings were unrelated to their findings, emphasizing its commitment to robust compliance. However, these events have fueled skepticism among lawmakers and regulatory bodies.
Additionally, a 2025 Reuters report indicated that the DOJ had paused corporate monitorships during an informal review. This followed the termination of monitorships for Glencore and Boeing, raising questions about the effectiveness of such oversight mechanisms.
Calls for Transparency
Blumenthal's letters underscore growing bipartisan concern over the enforcement of U.S. sanctions and AML laws in the cryptocurrency sector. As Binance seeks to project an image of corporate responsibility, the Senator's inquiry highlights the need for transparency in its internal operations and compliance efforts. The DOJ and FinCEN have yet to respond to the Senator's request for details.
