Treasury's FinCEN Cuts MEXC From U.S. System Over $16B Flows

The U.S. Treasury's Financial Crimes Enforcement Network issued a final order Friday that will cut offshore exchange MEXC Global off from the American banking system over alleged links to sanctions evasion by Iran, North Korea and Russia, the department said, according to Bitcoin Magazine. FinCEN's order finds MEXC a "primary money laundering concern in connection with Russian illicit finance" under section 9714(a) of the Combating Russian Money Laundering Act, and puts the alleged illicit volume behind the cut-off at $16B or more between May 2021 and May 2026.

The Event: A Funds-Transmittal Ban, Not a Sanctions Designation

According to Bitcoin Magazine, the order was signed by FinCEN Deputy Director Jimmy L. Kirby and was published as a PDF pending placement in the Federal Register. Thirty days after that Register notice is published, covered U.S. financial institutions will be barred from any funds transfer — including convertible virtual currency — to or from MEXC. Reuters reported the same cut-off Friday afternoon, Bitcoin Magazine said. Treasury framed the action as part of Operation Economic Outcast.

The order is not an OFAC sanctions designation. Bitcoin Magazine's reporting notes the order itself states it does not rewrite Bank Secrecy Act duties or OFAC rules, and it is a FinCEN funds-transmittal ban rather than a Section 311 proposed rulemaking. As of Friday evening eastern time, the Federal Register's public index still showed no MEXC document, matching the order's own cover note that publication is pending — meaning the 30-day countdown toward an enforceable transfer ban had not yet begun as of that reporting.

The order covers MEXC Global and named affiliates operating outside the United States, including Seychelles-incorporated MEXC Global Ltd / MX Global Ltd, Estonia's MEXC Estonia OÜ, Switzerland's GIDA Technology AG, and the U.K.'s MXC Global Ltd, plus successors, per Bitcoin Magazine. Covered institutions face civil or criminal penalties for willful violations.

The Allegations: Russia, Iran and North Korea Flows

Treasury's order alleges MEXC facilitated at least $16 billion in illicit flows over the five-year window, including nearly $1.5 billion tied to Russian sanctions evasion and about $22 million linked to Iran's Central Bank and the Islamic Revolutionary Guard Corps' Qods Force, Bitcoin Magazine reported. The platform was still processing trades with sanctioned exchange Garantex and its successor Grinex as recently as June 2026 — more than four years after OFAC designated Garantex, according to the release cited by Bitcoin Magazine.

Beyond Russia, FinCEN cites about $1 billion in direct traffic between MEXC and more than 40 Iranian crypto exchangers, nearly $26 million with the OFAC-sanctioned A7 sanctions-evasion network, and almost $200 million tied to the A7A5 stablecoin, per Bitcoin Magazine's account of the order. DPRK facilitators and cybercrime flows are also alleged, though the report does not break those out into a specific dollar figure.

MEXC has not issued a public response to the Friday order, and the exchange's main X account continued posting marketing content through the afternoon, Bitcoin Magazine reported.

Background: An Exchange Already Under Regulatory Scrutiny

Founded in 2018 and formerly branded MXC, MEXC ranks among the world's 20 largest centralized crypto venues by volume, according to Bitcoin Magazine's report. Treasury puts the exchange's daily turnover above $1 billion and reserves near $5 billion as of mid-2026, with access claimed across more than 170 countries. The exchange already lists the United States as a prohibited jurisdiction in its own user terms, so Friday's action mainly targets any remaining dollar rails, banking partners and counterparties that still touch U.S. institutions, the report said.

Other regulators have circled MEXC for years. The U.K. Financial Conduct Authority put MEXC Global Ltd on its warning list in March 2024 as unauthorized, Bitcoin Magazine reported. Hong Kong's Securities and Futures Commission warned the same month that the platform was marketing to local investors without a licence. Seychelles' Financial Services Authority said in May 2026 it took action against MX Global Ltd for unlicensed virtual-asset operations — a point footnoted in FinCEN's order, according to Bitcoin Magazine.

CoinHours analysis: What the Order Actually Changes

CoinHours analysis: The distinction Bitcoin Magazine's reporting draws between an OFAC sanctions designation and a FinCEN 9714(a) funds-transmittal finding matters for how the action should be read. The order is narrower in formal scope: it bans covered U.S. financial institutions from moving funds, including virtual currency, to or from the exchange once the Federal Register notice is published and the 30-day window expires. As of Friday evening no Register document had appeared, so the compliance clock had not started.

The practical effect described in the reporting is still significant. Once the order takes effect, U.S. banks, money transmitters and other covered firms cannot move dollars or crypto to MEXC wallets or accounts, according to Bitcoin Magazine. Offshore users may keep trading peer-to-peer, but dollar on-ramps and any bank that still clears for MEXC become a legal risk. Because MEXC already bars U.S. users under its own terms, the order bears mainly on those residual banking and counterparty links rather than on American retail customers.

The order also follows a template FinCEN has used before. Bitcoin Magazine's report draws a parallel to earlier 9714 cut-offs of venues such as Bitzlato, and places Friday's action within what it calls a busy sanctions week that had already included North Korea crypto designations and an Iranian exchange action. For now, the paper trail is specific: a final FinCEN order under section 9714(a), a 30-day fuse that starts only after Federal Register publication, and Treasury's claim of at least $16 billion in illicit volume behind the cut-off.

What to Watch

The open question flagged in Bitcoin Magazine's reporting is whether MEXC will contest the finding, seek an exemption, or quietly reroute liquidity before the Register notice lands. The Federal Register publication date is the key marker, since that event starts the 30-day countdown to when covered U.S. institutions must stop processing transfers to or from MEXC and its named affiliates. Until that notice appears, the penalties for willful violations remain pending rather than active.
