The U.S. Treasury Department has moved to restrict cryptocurrency exchange MEXC Global from accessing the American financial system after identifying $16 billion in transactions allegedly connected to sanctioned jurisdictions, including Iran, North Korea, and Russia.
According to The Financial Crimes Enforcement Network (FinCEN) announced the action on November 6, identifying MEXC Global as a significant money laundering concern. Treasury officials cited alleged weaknesses in the exchange’s anti-money laundering controls and questioned whether its transaction monitoring systems adequately addressed suspicious financial activity.
The $16 billion figure refers to transactions linked to the identified jurisdictions. It does not represent confirmed criminal proceeds.
FinCEN Cites MEXC Global's Anti-Money Laundering Deficiencies
FinCEN's order focuses on MEXC Global's transaction monitoring practices and financial activity involving jurisdictions subject to U.S. sanctions. Investigators identified significant deficiencies in the exchange's anti-money laundering systems, which allegedly allowed suspicious transactions to move through its platform.
MEXC Global had previously stated that its compliance policies restricted access for users in prohibited jurisdictions, including Iran and North Korea. However, Treasury officials concluded that those safeguards did not adequately address the financial risks identified during the investigation.
The department subsequently used its enforcement authority to restrict the exchange's access to U.S. financial institutions. Treasury Secretary Scott Bessent emphasized that financial institutions cannot support sanctioned Iranian activities while continuing to maintain access to American markets.
Bessent also reiterated Washington's commitment to disrupting financial networks suspected of helping Iran circumvent economic sanctions through cryptocurrency transactions.
US Treasury Expands Enforcement Against Crypto Platforms
The action against MEXC Global follows a series of U.S. enforcement measures targeting cryptocurrency platforms allegedly involved in transactions connected to sanctioned entities.
In June, American authorities sanctioned Iranian cryptocurrency exchange Nobitex over allegations involving the country's digital asset transactions. Treasury officials reported that Nobitex processed more than half of Iran's cryptocurrency inflows during 2025.
In September, authorities imposed additional restrictions on Iranian exchange BitBank over alleged Bitcoin transfers involving the Islamic Revolutionary Guard Corps.
These cases reflect Washington's broader efforts to prevent cryptocurrency platforms and financial networks from being used to evade economic sanctions. The latest order involving MEXC Global extends that enforcement approach to a platform accused of facilitating substantial transaction activity connected to multiple sanctioned jurisdictions.
For the cryptocurrency industry, the action highlights the importance of effective transaction monitoring and anti-money laundering controls, particularly when exchanges handle activity involving jurisdictions subject to international restrictions.
