Billion

Binance has stopped processing cryptocurrency transfers involving MEXC and its affiliated entities after US regulators designated the exchange a primary money laundering concern over at least $16 billion in alleged illicit transactions.
The <a href="https://www.binance.com/en/support/announcement/detail/9ef6e347da924cdc90f53577ab483b1f" rel="noopener noreferrer nofollow">restrictions announced November 10</a> cover more than a dozen entities associated with MEXC, including MEXC Global Limited, MEXC Estonia OÜ, GIDA Technology AG and MEXC Singapore Pte Ltd.
Outgoing transfers from Binance to the affected entities will be rejected, while incoming deposits will be temporarily withheld for compliance reviews. Customers attempting direct or indirect transactions with MEXC could face additional account restrictions or termination of services.
The measures follow a November 6 enforcement action by the US Treasury’s Financial Crimes Enforcement Network (<a href="https://cryptoadventure.com/community/articles/the-role-of-the-sec-and-other-regulatory-bodies-in-crypto/" rel="noopener noreferrer nofollow">FinCEN</a>), which accused MEXC of facilitating substantial transactions involving Russian sanctions evasion, Iranian financial networks, North Korean actors and cybercriminal operations.

MEXC allegedly processed at least $16 billion in illicit financial activity between May 2021 and May 2026, including nearly $1.5 billion connected to Russian sanctions evasion.
The <a href="https://cryptoadventure.com/mexc-cut-off-from-u-s-financial-system-over-16b/" rel="noopener noreferrer nofollow">US Treasury investigation</a> identified approximately $1 billion in direct transactions involving more than 40 Iranian cryptocurrency exchanges and $22 million benefiting Iran’s central bank and the Islamic Revolutionary Guard Corps.
MEXC also allegedly continued handling transactions involving sanctioned Russian exchanges Garantex and Grinex as recently as June 2026.
FinCEN’s <a href="https://www.federalregister.gov/documents/2026/11/10/2026-22962/imposition-of-special-measure-prohibiting-the-transmittal-of-funds-involving-mexc-global" rel="noopener noreferrer nofollow">formal prohibition</a> takes effect December 10, barring covered US financial institutions from transmitting funds to or from MEXC Global. The order does not itself freeze customer holdings or prohibit trading on the exchange outside its specified scope.
Binance’s restrictions closely resemble its <a href="https://cryptoadventure.com/binance-to-restrict-htx-exmo-and-nine-other-platforms-from-august-23/" rel="noopener noreferrer nofollow">August decision to block transfers involving HTX, EXMO and nine other platforms</a> following European sanctions targeting Russia-linked financial activity.
The HTX restrictions subsequently triggered wider compliance problems, with <a href="https://cryptoadventure.com/kraken-restores-accounts-after-12000-htx-linked-dust-transfers-trigger-compliance-locks/" rel="noopener noreferrer nofollow">Kraken temporarily locking accounts after nearly 12,000 small HTX-linked transfers</a> activated sanctions screening.
<h2 id="mexc-challenges-action-as-withdrawals-increase">MEXC Challenges Action as Withdrawals Increase</h2>
MEXC CEO Vugar Usi confirmed that the exchange has <a href="https://x.com/usithetalk/status/2120006569622712734" rel="noopener noreferrer nofollow">opened communication with FinCEN through US law firms</a>. The regulator acknowledged receiving a written request from MEXC on Monday, and the company intends to cooperate with the investigation.
MEXC has also launched an independent review of its anti-money laundering and sanctions controls.
Withdrawals have increased since the designation, but Usi maintains that <a href="https://x.com/usithetalk/status/2119080482579341694" rel="noopener noreferrer nofollow">deposits, withdrawals and trading remain operational</a>. The exchange has not reported a suspension of customer withdrawals.
Onchain investigator ZachXBT <a href="https://x.com/zachxbt/status/2120100614361530424" rel="noopener noreferrer nofollow">questioned the scale of FinCEN’s allegations</a>, arguing that large exchanges routinely process substantial flows associated with illicit activity.
While acknowledging MEXC’s historically relaxed compliance practices, he called for greater transparency around the $16 billion calculation, including comparisons with competing exchanges and the proportion of total trading activity considered illicit.
ZachXBT also questioned the enforcement disparity between MEXC, HTX and other exchanges, revisiting concerns he previously raised about <a href="https://cryptoadventure.com/zachxbt-says-uk-sanctions-on-htx-have-made-onchain-risk-scores-meaningless/" rel="noopener noreferrer nofollow">sanctions-related risk scores affecting ordinary HTX users</a>.
Binance has not specified how long incoming MEXC transfers may remain under compliance review or whether affected accounts will regain normal access once the checks are completed.
