Binance blocks MEXC transfers as FinCEN order cites $16.7bn in illicit transactions

In short

• Binance said on 10 November 2026 it will decline transfers from Binance accounts to MEXC and 12 related entities.
• Deposits from those MEXC entities will be held for compliance review, with possible account restrictions or offboarding.
• FinCEN's order bars covered US financial institutions from transmittals involving MEXC Global from 10 December 2026.
• FinCEN alleges MEXC Global moved at least $16bn in illicit funds between May 2021 and May 2026.

Binance said on 10 November 2026 that it will decline any request to send funds from a Binance account to MEXC or its affiliates, and will temporarily hold deposits arriving from them for a compliance review. The block is already live, according to Binance's announcement and its post on X, while the US order behind it, FinCEN's ban on fund transfers involving MEXC Global, only takes effect on 10 December 2026.

Binance is one of the world's largest crypto exchanges, and MEXC is a rival trading venue. The US Treasury's Financial Crimes Enforcement Network (FinCEN), the agency that polices money laundering in the US financial system, published the MEXC order in the Federal Register on 10 November 2026 as 91 FR 72420, after issuing it on 6 November.

Binance acts a month before the US ban

The two moves are related but not the same. FinCEN's order, issued under section 9714(a) of the Combating Russian Money Laundering Act, prohibits covered US financial institutions from any transmittal of funds from or to MEXC Global. It is not an OFAC sanctions designation, and it does not by itself bind every exchange worldwide. Binance's restriction is its own platform policy, applied immediately and without a stated US-only limit, according to its announcement.

Binance's notice lists 13 names covered by the restriction, including MEXC Global Limited, MEXC Estonia OÜ, GIDA Technology AG, MXC Global Ltd, MEXC Global Foundation Ltd, MEXC Singapore Pte Ltd and MEXC (Comoros) Ltd, as well as MEXC, MEXC Global, MEX Global Ltd, MX Global LTD, MEX Exchange and MEXC affiliates. That list is broader than the entities FinCEN names in its order, which says its list 'includes, but is not limited to' those companies and any successors.

What does FinCEN allege about MEXC?

FinCEN's findings are allegations, not court rulings. The Treasury's press release says MEXC Global facilitated at least $16bn in illicit transactions between May 2021 and May 2026, connected to Iranian, North Korean and Russian sanctions evasion and to cybercrime. The order itself puts the figure at $16.7bn over the same period, including nearly $1.5bn linked to Russian sanctions evasion and $232m in direct transactions with US-, EU- and UK-sanctioned entities.

MEXC Global's profile and alleged sanctions links

FinCEN also says MEXC Global was still processing transactions with the sanctioned Russian exchanges Garantex and Grinex as recently as June 2026, and that it handled almost $200m connected to the A7A5 stablecoin, a ruble-backed token used by the A7 network to move value around banking restrictions. MEXC Global was founded in 2018, is incorporated in the Seychelles without a virtual asset service provider licence, and processed more than $1bn a day as of June 2026 with about $5bn in reserves, according to the order.

Rejected withdrawals and held deposits

For ordinary users, the practical effect is at the point of transfer. A withdrawal from Binance to an MEXC address will be rejected, and crypto sent from MEXC into Binance will be held while Binance reviews it. Binance said accounts may be restricted during that review and that it could take further action under its terms of use, including offboarding.

Open questions and MEXC's response

The announcement does not say how long a review takes, whether deposits made before 10 November are affected, or how Binance will police transfers it considers indirect. MEXC said on X on 7 November that it was reviewing the FinCEN order with its legal and compliance teams and that it was 'operating normally', with user assets secure.

• OKX founder Star Xu warned users on X, from his personal account and not in an official OKX notice, against transferring funds directly from MEXC to OKX, saying funds tied to affected platforms may be frozen.
• Reaction under Binance's post ranged from support to criticism, and several users asked about scope.
• ASPIRE_ (@aspire_investin) said on X that Binance cutting off MEXC that fast 'tells you how serious it is'.

Traders' reactions: timing, loyalty and criticism

• Harvey (@yorkeccak) said on X that the FinCEN order does not take effect until 10 December and is not an OFAC sanction, so Binance was moving a month early.

KING (@iamdeejayjet1) said on X that Binance was 'jealous' of MEXC and warned it not to push MEXC into rules that hold users' funds.

Agencai (@Turgay236590) said on X that the winner was MEXC and that people should leave Binance and use MEXC instead.

Official_XEN1 (@Official_XEN1) said on X that Binance was looking for someone to blame and warned of 'FTX 2.0'. TECHNOLGY475191 and BrandonDev_ asked on X whether deposits made one to two months ago would be frozen, and whether the measures apply worldwide or only to US users. The announcement does not answer either question. ZachXBT said in his own opinion that FinCEN's $16bn figure looks overstated, and questioned why offshore exchanges moved so quickly to cut off MEXC users. These are individual views, not verified findings.

FinCEN's ban on MEXC Global from 10 December

FinCEN's order becomes effective on 10 December 2026, when covered US financial institutions must stop processing fund transfers involving MEXC Global. The order sets no end date. Violations may bring civil or criminal penalties, and the order leaves existing Bank Secrecy Act duties and OFAC sanctions in place.

What is still unclear for users

Binance has said it may restrict accounts during a review and could offboard users. The announcement gives no review timeline, and FinCEN's $16bn figure is an allegation, not a court finding; MEXC says it is reviewing the order.

Reader questions on Binance's MEXC block

Is my money safe if I sent funds from MEXC to Binance?

Binance said deposits from MEXC and the 12 other listed entities will be temporarily withheld and subject to a compliance review. Binance said accounts may be restricted during that review and that it could take further action under its terms of use, including offboarding. The announcement gives no review timeline.

How is Binance's MEXC block different from FinCEN's order?

Binance's restriction is its own platform policy, applied immediately and without a stated US-only limit, according to its announcement. FinCEN's order, issued on 6 November 2026 under the Combating Russian Money Laundering Act, prohibits covered US financial institutions from transmittals involving MEXC Global and takes effect on 10 December 2026. It is not an OFAC sanctions designation.

What does FinCEN allege against MEXC Global?

FinCEN alleges MEXC Global facilitated at least $16bn in illicit transactions between May 2021 and May 2026, according to the Treasury's release, a figure the order puts at $16.7bn. FinCEN links the funds to Russian, Iranian and North Korean sanctions evasion and to cybercrime. These are allegations, not court findings, and MEXC said it was reviewing the order.

When does the FinCEN ban on MEXC Global start?

FinCEN's order takes effect on 10 December 2026, 30 days after its publication in the Federal Register on 10 November 2026 as 91 FR 72420. From that date, covered US financial institutions are prohibited from any transmittal of funds from or to MEXC Global. The order sets no end date.

Why Binance's timing stands out

At InvestIn.News , we think the more telling part of this story is Binance's decision to cut MEXC-linked transfers a month before the US ban starts. FinCEN's order binds covered US financial institutions from 10 December, yet Binance has applied a global block now. OKX's founder Star Xu has separately warned users on X against sending funds directly from MEXC to OKX, though that was a personal post, not an official OKX notice. That is compliance contagion: a designation can push platforms to cut ties before any legal deadline.

The gap matters for users. Binance's notice lists 13 MEXC entities, broader than the companies FinCEN names, and it holds incoming deposits for a review of unstated length, with possible offboarding. Traders are left guessing whether older deposits are caught and how 'indirect' transfers will be policed.

We would also keep FinCEN's figures in perspective. The $16bn in the Treasury release and the $16.7bn in the order are allegations covering May 2021 to May 2026, not court findings, and ZachXBT has publicly said in his own opinion that the $16bn figure looks overstated. MEXC says it is operating normally while it reviews the order. Whether other major exchanges issue matching official notices is not established.
