US Treasury Cuts MEXC Off From the Financial System Over $16 Billion in Illicit Flows

Published November 6, 2026, 4:20 AM PKT. Based on the US Department of the Treasury press release and the Financial Crimes Enforcement Network order of November 6, 2026 (primary sources), with reporting by Bitcoin Magazine and news.bitcoin.com on November 6, 2026 (secondary reporting).

The US Treasury's Financial Crimes Enforcement Network (FinCEN) issued an order on Friday, November 6, 2026, effectively cutting crypto exchange MEXC Global off from the US financial system, alleging the platform facilitated at least $16 billion in illicit transactions connected to Iranian, North Korean and Russian sanctions evasion, as well as cybercrime, including by transacting directly with sanctioned actors. The order, issued as part of Operation Economic Outcast, prevents US financial institutions from processing funds transfers involving MEXC Global once it takes effect, FinCEN said. Treasury Secretary Scott Bessent said financial institutions cannot have it both ways, adding, "Either you support the Iranian regime, or you have access to the U.S. financial system."

At least $16 billion in illicit flows over five years

Treasury's figures cover May 2021 through May 2026. In that period, MEXC Global facilitated the movement of at least $16 billion in funds connected to sanctions evasion, cybercrime and other illicit activity, according to the department's release. Nearly $1.5 billion of that total was tied to Russian sanctions evasion, including $232 million in direct transactions with US, EU and UK sanctioned entities. MEXC also facilitated at least $26 million in transactions benefiting the Russia based, OFAC sanctioned A7 sanctions evasion network, and processed almost $200 million in transactions connected to the A7A5 stablecoin ($A7A5), a store of value Treasury says the A7 Network uses to help clients evade sanctions. On the Iranian side, MEXC sent or received approximately $1 billion in direct transactions with more than 40 identified Iranian crypto exchangers, some of them subject to US and international sanctions, and facilitated approximately $22 million in transactions for the Central Bank of Iran and the Islamic Revolutionary Guard Corps and its Qods Force, both sanctioned by the US, the EU and the UK. Treasury also cites ransomware and scam payments and Russian and other darknet market activity among the flows MEXC handled.

Still trading with Garantex in June 2026

The most pointed detail in Treasury's release is how recently the alleged conduct continued. MEXC Global was still processing transactions with sanctioned Russian entity Garantex, and its successor Grinex, as recently as June 2026, more than four years after Garantex's April 2022 designation by Treasury's Office of Foreign Assets Control (OFAC), the release said. That finding underpins the legal basis for the order: FinCEN found MEXC Global a "primary money laundering concern in connection with Russian illicit finance" under section 9714(a) of the Combating Russian Money Laundering Act. The order is not an OFAC sanctions designation, and FinCEN said it does not rewrite Bank Secrecy Act duties or OFAC rules. It is a funds transmittal ban, a final order rather than a proposed rulemaking, and Reuters reported the same cut-off on Friday afternoon, Bitcoin Magazine noted.

The 30-day clock has not started yet

The ban does not bite immediately. The order takes effect 30 days after publication in the Federal Register, and as of Friday evening eastern time the Register's public index still showed no MEXC document, matching the order's own cover note that publication is pending, Bitcoin Magazine reported. The order, signed by FinCEN Deputy Director Jimmy L. Kirby, covers MEXC Global and named affiliates operating outside the United States, including Seychelles incorporated MEXC Global Ltd and MX Global Ltd, Estonia's MEXC Estonia OÜ, Switzerland's GIDA Technology AG and the UK's MXC Global Ltd, plus successors. Covered institutions face civil or criminal penalties for willful violations, and the order does not change existing obligations under the Bank Secrecy Act, including Suspicious Activity Report filing requirements. FinCEN also pointed tipsters to its whistleblower incentive program, which can pay awards when information leads to enforcement action with monetary penalties above $1,000,000.

A top-20 exchange already under pressure abroad

MEXC is a large venue, not a fringe one. Founded in 2018 and formerly branded MXC, it ranks among the world's 20 largest convertible virtual currency exchangers by volume, Treasury said, processing more than $1 billion in daily transactions and holding approximately $5 billion in reserves as of September 2026, with trading in more than 50 currencies and access to more than 3,000 different cryptocurrencies and tokenized assets across more than 170 countries. The platform says it maintains anti-money laundering and customer identification policies and explicitly prohibits use by or on behalf of people in certain jurisdictions, including Iran and North Korea, but Treasury said severe deficiencies in its controls allowed it to facilitate transactions for people and entities in those prohibited jurisdictions. The exchange already lists the United States as a prohibited jurisdiction in its user terms, so Friday's action mainly hits any remaining dollar rails, banking partners and counterparties that still touch US institutions, Bitcoin Magazine reported. Regulators elsewhere have been circling for years: the UK Financial Conduct Authority put MEXC Global Ltd on its warning list in March 2024 as unauthorized, Hong Kong's Securities and Futures Commission warned the same month that the platform was marketing to local investors without a licence, and Seychelles' Financial Services Authority said in May 2026 it took action against MX Global Ltd for unlicensed virtual asset operations. MEXC has not issued a public response to the Friday order, and its main X account kept posting marketing content through the afternoon, Bitcoin Magazine reported. The template tracks an earlier 9714(a) cut-off of Bitzlato, and the order lands in a busy sanctions week that has already seen North Korea crypto designations and an Iranian exchange action, Bitcoin Magazine noted.
