The Financial Crimes Enforcement Network (FinCEN), the US Treasury’s anti-money laundering unit, has cut MEXC Global off from the US financial system. According to the order dated November 6, 2026, the exchange allegedly facilitated at least $16 billion in illicit transactions between May 2021 and May 2026, tied to Iran, Russia, North Korea and cybercrime.
🔑 Key takeaways
- FinCEN bars US financial institutions from processing transfers involving MEXC Global, crypto included, effective 30 days after publication in the Federal Register.
- Treasury puts illicit flows at no less than $16 billion, including about $1 billion linked to Iran and about $1.5 billion tied to Russian sanctions evasion.
- MEXC says deposits, withdrawals and trading are running normally and has announced an independent review of its controls.
- The order does not directly freeze customer assets and does not require MEXC to shut its services worldwide.
An order issued under Section 9714(a)
The order rests on Section 9714(a) of the Combating Russian Money Laundering Act. FinCEN classified MEXC Global as a foreign financial institution of primary money laundering concern in connection with Russian illicit finance. It forms part of Operation Economic Outcast, a Treasury campaign launched in August to cut off financial networks helping Iran evade sanctions. The same day, the Office of Foreign Assets Control (OFAC) designated eight Canada-based money services businesses accused of facilitating support for the Iranian regime.
The prohibition covers the US financial institutions in scope, which may no longer process fund transfers involving MEXC Global, including crypto transfers. It also extends to branches, subsidiaries and successor entities of MEXC operating outside the United States. Cryptoast specifically cites subsidiaries in the Seychelles, Estonia, Switzerland and the United Kingdom. A key point: the order takes effect only 30 days after publication in the Federal Register, and the sources do not specify when that publication occurs. Covered institutions that violate the restrictions could face criminal or civil penalties.
Unlike a direct OFAC sanction, the order does not trigger a direct freeze of customer assets. It is a restriction on access to the US banking system, not a blocking measure on funds held on the platform.
“Financial institutions cannot play both sides: either you support the Iranian regime, or you have access to the US financial system.”
Scott Bessent, US Treasury Secretary
Bessent added that Treasury will keep cutting off the economic lifelines of the Iranian regime and thwarting its desperate attempts to evade US sanctions using digital assets.
Heavy flows tied to Iran and Russia
FinCEN breaks the activity into several distinct strands. The table below summarises the amounts attached to each, as reported by the sources. They do not form an exhaustive breakdown of the headline total.
| Strand | Reported amount | Detail |
|---|---|---|
| Iran (platforms) | about $1 billion | Transfers with more than 40 Iranian exchanges |
| Iran (central bank and Guards) | about $22 million | Including the Qods Force |
| Russia (evasion) | about $1.5 billion | Treasury estimate |
| Garantex / Grinex | $129M / $4.1M | Activity after their respective designations |
| Sanctioned entities (US, EU, UK) | $232 million | Direct transactions |
| A7 / A7A5 | $26M / nearly $200M | A7 network and ruble-backed stablecoin |
Between May 2021 and May 2026, MEXC sent or received roughly $1 billion in transfers involving more than 40 Iranian crypto exchanges, some of which are subject to international sanctions. About $22 million reportedly benefited Iran’s central bank and the Islamic Revolutionary Guard Corps, including its Qods Force. FinCEN also flags flows involving sanctioned North Korean actors, without a separate figure in the available sources.
On the Russian side, Treasury estimates about $1.5 billion in transactions linked to sanctions evasion. MEXC allegedly kept dealing with Garantex, a Russian platform sanctioned in April 2022, and then with its successor Grinex until June 2026. FinCEN puts direct activity with Garantex at roughly $129 million and with Grinex at $4.1 million after their designations. The Treasury statement also cites $232 million in direct transactions with entities sanctioned by the United States, the European Union and the United Kingdom.
The A7 network reportedly benefited from at least $26 million in transactions, while nearly $200 million is linked to A7A5, a ruble-backed stablecoin used to facilitate sanctions evasion. Other transactions are attributed to cybercrime. Despite MEXC’s stated policies prohibiting activity involving sanctioned jurisdictions, FinCEN concluded that weaknesses in its anti-money laundering controls allowed prohibited operations to continue.
The headline figure also varies by source. The FinCEN release says “at least $16 billion”, while The Defiant, citing the order, reports $16.7 billion in flows linked to Russian illicit finance and other illicit activities. The sources provided do not explain the gap, so readers should treat the exact total with caution.
A major platform already under scrutiny
MEXC was founded in 2018 and says it operates in more than 170 countries. Cryptoast describes it as one of the twenty largest exchanges in the world. According to Treasury, it handled more than $1 billion in daily trading volume and held roughly $5 billion in reserves as of September 2026. It offered access to more than 3,000 cryptocurrencies and tokenized assets.
| Metric | Value | Reference |
|---|---|---|
| Daily trading volume | above $1 billion | US Treasury |
| Reserves | about $5 billion | US Treasury, September 2026 |
| Total assets | about $4.48 billion | DefiLlama, Friday November 6 |
| Assets offered | more than 3,000 | Cryptocurrencies and tokenized assets |
The reserves and total-assets figures are not directly comparable: the indicators and reference dates differ, and the sources do not detail their methodology. The platform is also not new to regulators. In March 2024, the UK Financial Conduct Authority placed it on its warning list. In Europe, it had stopped serving the Netherlands due to non-compliance with the MiCA regulation.
MEXC’s response and business continuity
At the time of Cointelegraph’s publication, MEXC had not yet responded to requests for comment. In a statement published on Saturday, November 7, the platform said deposits, withdrawals and transactions were operating normally. It wrote on its verified X account:
“User assets remain secure”
MEXC, official X account
MEXC said it has launched an independent review or audit of its anti-money laundering and sanctions compliance controls. Its legal and compliance teams are examining the FinCEN order, and the company said it wants to engage constructively with the regulator and other authorities. The name of the independent auditor and the review timeline have not been disclosed.
A point of caution: the user account page, updated on October 13, already listed the United States among prohibited jurisdictions. Beyond MEXC’s statements on continuity of operations, the sources provide no quantified data on any change in price, trading volume or assets.
Outlook and scenarios
The MEXC case illustrates the tougher US stance toward platforms that act as conduits for sanctions evasion. Three scenarios stand out. In the first, the independent review demonstrates robust controls and the impact remains confined to flows involving covered US institutions. In the second, the order takes effect after Federal Register publication without remediation, reducing the platform’s access to the US banking system and weighing on its liquidity. In the third, additional sanctions or stepped-up pressure from the FCA and European regulators, notably under MiCA, widen the perimeter.
For users and observers alike, three indicators deserve close attention: the exact Federal Register publication date, the identity and scope of the independent auditor, and the trajectory of trading volumes and reserves. Without this data, any projection for MEXC’s activity remains speculative.
