MEXC Faces US Financial Cutoff Over Alleged $16 Billion in Illicit Transactions

What happened: FinCEN issued an order on November 6 prohibiting US financial institutions from processing transfers involving Seychelles-incorporated MEXC Global, citing approximately $16 billion in alleged illicit transactions between May 2021 and May 2026. The supplied reporting identifies approximately $1.5 billion tied to alleged Russian sanctions evasion and approximately $1 billion linked to more than 40 Iranian money changers, with Treasury also alleging continued processing for Garantex and its successor Grinex as recently as June 2026. The restriction takes effect 30 days after Federal Register publication, while separate reporting identified $126 million in MEXC outflows following the action.

Why it matters: The consequential issue is access to financial intermediaries: the order addresses what US financial institutions may process, making its implementation timetable more useful to counterparties than a broad description of MEXC as simply being banned. CoinDesk’s distinction between Treasury’s Iran-focused presentation and the order’s emphasis on alleged Russian illicit finance also matters, because it identifies the specific conduct underlying the action rather than treating different sanctions allegations as interchangeable. The reported exchange outflows indicate funds moving away after the announcement, but they do not independently establish insolvency, prove Treasury’s allegations, or reveal whether those withdrawals will persist through implementation.
