The US Treasury on Friday ordered MEXC Global's exclusion from the US financial system over allegations involving at least $16 billion in illicit transactions. The order prohibits US financial institutions from handling transfers involving MEXC and takes effect 30 days after Federal Register publication. FinCEN alleged that MEXC processed transactions involving sanctioned groups in Iran, Russia and North Korea between May 2021 and May 2026. MEXC had not answered a request for comment by publication.
