On 6 November the Financial Crimes Enforcement Network of the U.S. Treasury issued an order that cuts MEXC Global out of the American financial system. It is not a sanction the way the industry is used to reading them: no wallet on a list, no exchange added to the OFAC roll. It is something more structural: U.S. banks cannot process any transfer of funds from or to the platform, cryptocurrencies included. The order becomes operative thirty days after publication in the Federal Register.

The numbers behind the charge

According to FinCEN, between May 2021 and May 2026 MEXC moved at least 16 billion dollars tied to sanctions evasion, cybercrime and other illicit activity. Inside the total: almost 1.5 billion from Russian evasion, of which 232 million in direct transactions with parties sanctioned by the U.S., the EU and the UK; about one billion with more than 40 Iranian exchanges; 22 million for Iran’s central bank and for the Revolutionary Guards and the Qods Force; 26 million to the A7 network and almost 200 million tied to the A7A5 stablecoin. The detail that makes it hard to speak of an oversight: MEXC was still processing transactions with Garantex, and with its successor Grinex, until June 2026, more than four years after the OFAC designation.

Why it is a different weapon

The order rests on section 9714(a) of the Combating Russian Money Laundering Act, a law designed for Russian money laundering and used here inside “Operation Economic Outcast”, the campaign launched in August against Iran’s facilitators. The mechanism is the severing of correspondent banking: it does not matter where MEXC is based, what matters is that no American bank can touch its flows. “Either you support the Iranian regime, or you have access to the U.S. financial system,” said Treasury Secretary Scott Bessent. Compliance, in short, is not a product requirement: it is a jurisdictional permit.

The gap between policy and practice

MEXC is among the world’s top twenty exchanges, with more than one billion dollars in daily trading and about 5 billion in reserves as of September 2026; DefiLlama attributed 4.48 billion in assets to it on the day of the order. It declared anti-money-laundering policies and banned use from jurisdictions such as Iran and North Korea. FinCEN speaks of “grave deficiencies”: the gap between the document and the behaviour is, here, the entire charge. The exchange had not responded to Cointelegraph.

The week was a concentrate of rules. On 5 November Nigeria’s central bank banned algorithmic stablecoins and imposed local licences, with one hundred and eighty days to comply. On 17 November the Bank of Russia opens public consultations, exempting qualified investors from purchase limits. Three jurisdictions, three instruments — licence, calendar, exclusion from banks — and the same direction.

The lesson is not that cryptocurrencies have been banned. It is that access to banking infrastructure remains the choke point, and that no trading volume shields you from an office that turns off the tap. Whoever builds on centralised exchanges should treat the intermediary’s legal residence as counterparty risk, not as an administrative detail.
