FinCEN orders a US cutoff of funds transfers with MEXC over $16 billion in alleged illicit flows

FinCEN ordered US institutions to stop transfers with MEXC, citing at least $16 billion in alleged illicit flows. What the order does and how MEXC replied.

The US Treasury’s Financial Crimes Enforcement Network (FinCEN) has ordered US financial institutions to stop sending money to, or receiving money from, MEXC Global. Treasury announced the step on 6 November 2026 as part of Operation Economic Outcast, saying the exchange facilitated at least $16 billion in illicit transactions connected to Iranian, North Korean and Russian sanctions evasion, as well as cybercrime.

This is separate from FinCEN and the Federal Reserve’s withdrawal of a 2020 plan to lower the international transfer-tracking threshold to $250. Friday’s order targets one platform.

What the order does

Treasury said the order was issued under section 9714(a) of the Combating Russian Money Laundering Act and bars US financial institutions from any transmittal of funds from or to MEXC Global. Violations may bring civil or criminal penalties. Bank Secrecy Act duties, including suspicious-activity reporting, and OFAC sanctions are unchanged. The order takes effect 30 days after publication in the Federal Register.

CoinDesk reported that the ban covers crypto transfers as well as conventional payments, and that MEXC is the largest crypto exchange yet targeted under Section 9714, after smaller cases against Bitzlato in 2023 and PM2BTC in 2024. The statute applies to a foreign institution only when FinCEN ties it to Russian illicit finance, even though Treasury presented the move under its Iran-focused campaign launched in August.

What Treasury alleges

Treasury said MEXC was founded in 2018 and, as of September 2026, processed more than $1 billion in daily transactions and held about $5 billion in reserves. It called the platform one of the world’s 20 largest convertible-virtual-currency exchangers, offering more than 50 currencies and more than 3,000 cryptocurrencies and tokenized assets.

Between May 2021 and May 2026, Treasury said, MEXC moved at least $16 billion tied to sanctions evasion, cybercrime and other illicit activity. That includes nearly $1.5 billion linked to Russian sanctions evasion, of which $232 million were direct deals with US-, EU- or UK-sanctioned entities. The department said MEXC was still processing transactions with sanctioned Russian exchange Garantex and its successor Grinex as recently as June 2026, more than four years after OFAC designated Garantex in April 2022. It also cited at least $26 million benefiting the OFAC-sanctioned A7 network and almost $200 million tied to the A7A5 stablecoin used by that network.

Treasury also said MEXC sent or received about $1 billion in direct transactions with more than 40 identified Iranian crypto exchanges, and about $22 million for the sanctioned Central Bank of Iran and the Islamic Revolutionary Guard Corps, including its Qods Force. It argued that “severe deficiencies” in MEXC’s anti-money-laundering controls allowed this activity even though the platform said it barred users in places such as Iran and North Korea. Secretary Scott Bessent said financial institutions “cannot have it both ways.” The Block placed the order alongside earlier steps against Iranian crypto venues, including sanctions on Nobitex in June and BitBank in September.

How MEXC responded

In a statement on its announcements page, MEXC said it was reviewing the 6 November order with its legal and compliance teams. The exchange said it is operating normally and that user assets remain secure. It said it takes the concerns seriously, intends to engage constructively with FinCEN and other authorities, and has begun an independent review of its AML and sanctions controls. The statement did not address Treasury’s specific figures.

The order restricts US financial institutions from moving funds to or from the platform. On the text Treasury published, it is not a seizure of customer balances. How banks, payment firms and other crypto venues treat MEXC during the 30-day run-up will decide how far the cutoff reaches in daily trading.

Why it matters

When a large exchange loses access to US dollar banking, counterparties often review their exposure, which can mean slower fiat ramps or precautionary withdrawals. Those effects are not automatic, and MEXC says trading continues as usual. The decision adds a weekend overlay to a cautious crypto market. Bitcoin was holding near the mid-$70,000s after a week of ETF outflows, while ether stayed close to $2,200. See our guide to whether crypto is safe on an exchange.

Bottom line

FinCEN has used a Russia-focused statute to isolate one of the larger global crypto exchanges from US fund transfers, citing at least $16 billion in alleged illicit flows over five years. MEXC says it is reviewing the order, operating normally and examining its controls. Next come Federal Register publication, the 30-day effective date, and whether other jurisdictions or banking partners follow Washington’s lead.
