US Treasury Slams MEXC With Financial-System Block Over Alleged Illicit Flows

Brief

By Dextape Desk · November 7, 2026

The US Treasury's FinCEN unit issued an order on November 6 barring US financial institutions from handling transfers to or from MEXC Global, a crypto exchange. The agency says the platform handled $16 billion or more in illicit activity from May 2021 through May 2026, with connections to circumvention of sanctions by networks in Iran, Russia and North Korea, along with cybercrime. The measure is not a worldwide ban and does not automatically freeze customer assets. It becomes operative thirty days after the Federal Register publishes it. Treasury also said MEXC kept processing transactions tied to Garantex and Grinex as late as June 2026. Russia-linked activity reached nearly $1.5 billion, while roughly $1 billion allegedly passed through direct dealings with more than 40 Iranian exchanges. Treasury argued these findings exposed weak anti-money-laundering controls despite the exchange's own bans on certain sanctioned jurisdictions.

Why it matters: It signals that US regulators can reach international crypto platforms through the banks that connect them to American finance, which could prompt tighter compliance checks across the industry.
