The US Treasury severs MEXC's access to the US financial system

What the order does

The order was issued on Friday 6 November 2026 under section 9714(a) of the Combating Russian Money Laundering Act, as part of Operation Economic Outcast, Treasury's campaign launched in August 2026. It prohibits US financial institutions from engaging in any transmittal of funds from or to MEXC Global, and violations may bring civil or criminal penalties. The order was signed by FinCEN Deputy Director Jimmy L. Kirby.

The legal finding behind it is specific: MEXC Global is a financial institution located outside the United States of "primary money laundering concern in connection with Russian illicit finance." The order also reaches beyond the main platform. Per Bitcoin Magazine's reading of the order, it covers MEXC Global and its affiliates and successors outside the US, including Seychelles incorporated MEXC Global Ltd and MX Global Ltd, MEXC Estonia OU, GIDA Technology AG in Switzerland, and MXC Global Ltd in the UK.

What the order does not do

The order has been widely reported as a ban, and the distinction matters. It is not an OFAC sanctions designation. It does not order MEXC to shut down worldwide, and it does not itself freeze customer deposits. It also does not change existing BSA and anti-money laundering reporting obligations, or OFAC obligations, for US institutions. What it removes is one specific thing: the ability of US financial institutions to transmit funds to or from MEXC, in either direction.

Timing matters too. The order takes effect 30 days after publication in the Federal Register. As of Friday evening 6 November 2026, the Federal Register had not yet published it, according to Bitcoin Magazine, so the 30 day countdown had not begun.

Treasury's allegations

The figures below are Treasury's allegations, covering May 2021 to May 2026. MEXC has not publicly answered them in the first reports; see the response section below.

• At least $16 billion in transactions connected to sanctions evasion, cybercrime and other illicit activity.
• Nearly $1.5 billion linked to Russian sanctions evasion, including $232 million in direct transactions with US, EU and UK sanctioned entities.
• Transactions with the sanctioned Russian exchange Garantex and its successor Grinex as recently as June 2026, more than four years after Garantex's April 2022 OFAC designation.
• At least $26 million benefitting the OFAC sanctioned A7 sanctions evasion network, and almost $200 million connected to the A7A5 stablecoin.
• Approximately $1 billion in direct transactions with more than 40 identified Iranian crypto exchangers.
• Approximately $22 million in transactions for the Central Bank of Iran and the IRGC and its Qods Force, which are sanctioned by OFAC and by the UK and EU.
• A hub, in Treasury's description, for North Korean (DPRK) sanctions evasion, ransomware and scam payments, and darknet market activity.
• Anti-money laundering controls with, in Treasury's words, severe deficiencies, even though MEXC states that it has AML and customer identification policies and prohibits users in Iran and North Korea.

MEXC in numbers

• Founded in 2018 and incorporated in the Seychelles. Per the order, it operates without a Seychelles VASP licence.
• A top 20 crypto exchanger globally, with more than $1 billion in daily transactions as of September 2026.
• About $5 billion in reserves, per Treasury. DefiLlama put MEXC's total assets at about $4.48 billion on 6 November 2026.
• More than 3,000 cryptocurrencies and tokenized assets listed, with trading in more than 50 currencies.

What this means if you use MEXC

• The direct bite is on banking rails, not on a US customer base. MEXC does not onboard US users under its own terms, but once the order is effective no US institution may send funds to or receive funds from MEXC.
• Expect fallout beyond the US. Correspondent banks and payment partners outside the US routinely follow US Treasury actions, so fiat on and off ramps in other countries may narrow as partners reassess the relationship.
• Trading is not directly halted, and deposits are not frozen by the order. Nothing in the order stops customers trading with each other on the platform.
• The risks are indirect but real: banking access, fiat ramps, liquidity, and counterparty confidence can all deteriorate before the effective date arrives, not after it.
• Weigh counterparty risk now rather than later. Keeping only trading balances on any single offshore exchange, and holding the rest in a wallet you control, is the standard advice we give for every venue, and it applies with extra force here.

MEXC's response

As of the first reporting on 6 and 7 November 2026, MEXC had not responded to Cointelegraph's request for comment by the time it published on 6 November, and it had issued no public statement in the first reports. If MEXC publishes a response, we will update this article and our MEXC review.
