The MEXC sanctions order announced by the US Treasury on November 6 prohibits covered US financial institutions from transmitting funds to or from the cryptocurrency exchange. FinCEN says it takes effect 30 days after publication in the Federal Register. The agency cites billions of dollars in funds connected to Russian illicit finance and other illicit activity.
- FinCEN issued the order under section 9714(a) of the Combating Russian Money Laundering Act.
- FinCEN says MEXC facilitated $16.7 billion connected to Russian illicit finance and other illicit activity from May 2021 through May 2026.
- Treasury estimated nearly $1.5 billion in transactions had direct or indirect exposure to Russian sanctions-evasion activity, including $232 million in direct transactions with sanctioned entities.
- The restriction applies to covered US financial institutions, not every MEXC user or transaction worldwide.
- As of June 2026, FinCEN said MEXC processed more than $1 billion in daily transactions and held approximately $5 billion in reserves.
Timeline of the MEXC sanctions

- October 20, 2026: MEXC announced it would discontinue services for users in Russia and Belarus. It said affected users would receive individual notices explaining how to close positions and withdraw assets.
- November 6, 2026: Treasury announced the FinCEN order. It takes effect 30 days after publication in the Federal Register, not simply 30 days after the announcement.
Background on the MEXC sanctions
The order finds MEXC Global to be a financial institution operating outside the United States that is of “primary money laundering concern” in connection with Russian illicit finance. FinCEN says the action also addresses activity connected to Iran, North Korea and cybercrime. The restriction applies to covered US financial institutions transmitting funds to or from MEXC.
Treasury says nearly $1.5 billion in MEXC transactions had direct or indirect exposure to Russian sanctions-evasion activity between May 2021 and May 2026. That included $232 million in direct transactions with entities sanctioned by the United States, the European Union or the United Kingdom. Treasury also cited approximately $1 billion in direct transactions with more than 40 identified Iranian crypto exchangers, and approximately $22 million in transactions for Iran’s sanctioned Central Bank and the Islamic Revolutionary Guard Corps and its Qods Force.
The FinCEN order says MEXC facilitated at least $26 million benefiting Russia-based A7 and processed almost $200 million connected to the A7A5 stablecoin. Treasury described A7A5 as being used by A7-linked actors to move value amid restricted or less dependable banking channels. Treasury also said MEXC transacted with Garantex and Grinex as recently as June 2026. The FinCEN order details the agency’s findings and legal basis.
As of June 2026, the order said MEXC processed more than $1 billion in daily transactions, held approximately $5 billion in reserves and ranked among the world’s 20 largest crypto exchangers by trading volume. These figures are not current measurements.
Reactions and market context
Treasury Secretary Scott Bessent said on November 6: “Financial institutions cannot have it both ways: Either you support the Iranian regime, or you have access to the U.S. financial system.” Treasury announced the measure as part of Operation Economic Outcast. The order prohibits covered US financial institutions from transmitting funds to or from MEXC, effective 30 days after Federal Register publication.
MEXC’s October announcement about discontinuing services for users in Russia and Belarus preceded the US order. It does not establish that MEXC had already changed services for US customers or that the new restriction was in force on November 6. The effective date depends on Federal Register publication.
Market figures in the supplied snapshot were mixed. CoinGecko data at 21:59 UTC on November 6 showed bitcoin at $75,813, up 0.13% over 24 hours, and ether at $2,235.52, up 0.52%. XRP was $1.18, down 3.38% over the same period. The Crypto Fear & Greed Index was 28, classified as Fear, on November 6, according to Alternative.me. These figures describe the wider market and do not establish a price reaction caused by the MEXC order.
What to watch next
The order takes effect 30 days after publication in the Federal Register. The supplied sources do not state whether MEXC has responded to the November 6 order or explain how it will affect individual account access, withdrawals or transfers. The specified restriction concerns covered US financial institutions transmitting funds to or from MEXC.
The order sets a restriction on covered institutions, but the supplied documents do not provide a universal answer about assets already held on the platform or individual account arrangements. MEXC’s October announcement said affected users in Russia and Belarus would receive notices explaining how to close positions and withdraw assets. That announcement does not establish what will happen to other customers.
