U.S. Treasury Excludes MEXC from Financial System Over Alleged $16 Billion

The Financial Crimes Enforcement Network (FinCEN) of the U.S. Treasury Department has issued a definitive order that effectively severs the offshore exchange MEXC Global from the American financial system. This action is due to alleged connections to sanctions evasion involving countries such as Iran, North Korea, and Russia.

According to the findings outlined in the order, which is available in PDF format pending its publication in the Federal Register, MEXC has been classified as a “primary money laundering concern in connection with Russian illicit finance” under Section 9714(a) of the Combating Russian Money Laundering Act. Following the issuance of the Federal Register notice, U.S. financial institutions will have a 30-day period during which they will be prohibited from conducting any funds transfers—whether in conventional currency or convertible virtual currency—to or from MEXC.

Reuters corroborated this development in their coverage on Friday afternoon. The Treasury has characterized this initiative as part of Operation Economic Outcast, emphasizing that it does not constitute an OFAC sanctions designation. The order clarifies that it does not alter Bank Secrecy Act obligations or OFAC regulations, and is categorized as a FinCEN funds transmittal ban rather than an initiative for proposed rulemaking under Section 311.

The Treasury Department alleges that MEXC facilitated approximately $16 billion in illicit financial flows from May 2021 to May 2026. This includes nearly $1.5 billion associated with evasion of Russian sanctions and around $22 million linked to activities involving Iran’s Central Bank and the Qods Force of the Islamic Revolutionary Guard Corps. Notably, reports indicate that MEXC continued to execute trades with sanctioned entities such as Garantex and its successor, Grinex, as recently as June 2026, despite Garantex being designated by OFAC more than four years prior.

Overview of the Order’s Implications

The order, which is signed by FinCEN Deputy Director Jimmy L. Kirby, applies to MEXC Global and its affiliates operating outside the United States, such as MEXC Global Ltd / MX Global Ltd, incorporated in Seychelles; MEXC Estonia OÜ; GIDA Technology AG in Switzerland; and MXC Global Ltd in the U.K., among any successors. Entities affected by this order may face civil or criminal penalties for willful infractions.

The 30-day countdown for compliance will commence only upon publication of the notice in the Federal Register. As of Friday evening (Eastern Time), the public index of the Register indicated the absence of any associated documents concerning MEXC, confirming that publication is still forthcoming.

Contextual Background on MEXC

Founded in 2018 and previously operating under the name MXC, MEXC is ranked among the top 20 centralized cryptocurrency exchanges globally in terms of trading volume. As per Treasury estimates, the exchange’s daily turnover exceeds $1 billion, with reserves nearing $5 billion as of mid-2026, while claiming access in over 170 countries. The exchange has preemptively classified the United States as a prohibited jurisdiction in its user agreements, meaning that the recent action primarily impacts any remaining banking relationships and dollar-based transactions with U.S. financial institutions.

Regulatory scrutiny has intensified over the years, with the U.K. Financial Conduct Authority placing MEXC Global Ltd on its warning list as unauthorized in March 2024. In the same month, Hong Kong’s Securities and Futures Commission expressed concerns regarding the platform’s marketing activities targeting local investors without the necessary licenses. Additionally, Seychelles’ Financial Services Authority disclosed in May 2026 that it had taken action against MX Global Ltd for operating virtual asset activities without a license, as cited in FinCEN’s order.

These compliance deficiencies are particularly significant because the allegations concerning illicit financial flows are specific and not merely based on associations. Beyond its dealings with Russia, FinCEN cites around $1 billion in direct transactions with over 40 Iranian crypto exchanges, nearly $26 million with the OFAC-designated A7 sanctions evasion network, and close to $200 million connected to the A7A5 stablecoin. Accusations also include facilitation by North Korean operatives and cybercrime-related transactions. As of the time of reporting, MEXC had not issued any public statement regarding the order; its primary account on the X platform continued to share marketing content throughout the afternoon.

Significance for Bitcoin Markets

From a practical standpoint, once the order is enforced, U.S. banks, money transmitters, and related entities will be unable to process dollar or cryptocurrency transfers to MEXC wallets or accounts. While offshore users may still engage in peer-to-peer trading, any bank or financial institution that facilitates transactions for MEXC will be exposed to legal risks. This situation mirrors previous restrictions similar to those imposed on other platforms like Bitzlato, coinciding with a significant week for sanctions that has already included new cryptocurrencies associated with North Korea, actions against an Iranian exchange, and Russia’s efforts to introduce bitcoin trading on the Moscow Exchange.

The course of action MEXC may take remains uncertain; it may choose to contest the findings, seek an exemption, or attempt to reroute liquidity quietly. For the time being, the data trail indicates a finalized FinCEN order under Section 9714(a), a 30-day compliance window following Federal Register publication, and Treasury’s assertion of at least $16 billion in illicit financial activities associated with the exchange.
