Binance Blocks MEXC Transfers Over $16B US Laundering Order

Binance Halts Transfers to MEXC Entities

Binance stopped processing transfers involving MEXC Global and its affiliates on November 10, four days after the US Treasury's Financial Crimes Enforcement Network moved to cut the exchange off from the American financial system. In a compliance notice published on its support portal, Binance instructed customers not to send or receive funds directly or indirectly through its platform in connection with MEXC and 12 other named entities or categories linked to the exchange. Withdrawals from Binance wallets to the listed entities are now rejected, while deposits arriving from them are temporarily withheld pending compliance checks. Customers whose incoming funds get flagged can face restrictions on their own accounts during the review, and Binance said it may impose further limits or terminate their access to its services under its terms of use. The covered list spans MEXC Global Limited, MEXC Estonia OÜ, GIDA Technology AG, MXC Global Ltd, MEXC Global Foundation Ltd, MEXC Singapore Pte Ltd and MEXC (Comoros) Ltd, alongside other names and affiliates identified in the notice. Binance did not specify how long the reviews could take or set a separate timetable for releasing withheld deposits. The underlying order came from FinCEN on November 6, which designated MEXC a primary money laundering concern under Section 9714 of the Combating Russian Money Laundering Act, a provision that allows restrictions on foreign financial institutions tied to Russian illicit finance. The Treasury's press release states that at least $16 billion passed through the exchange between May 2021 and May 2026 in transactions connected to sanctions evasion, cybercrime and other illegal activity involving Russia, Iran and North Korea. US authorities identified roughly $1 billion in direct transfers involving more than 40 Iranian cryptocurrency exchanges, some already under sanctions, and $22 million tied to Iran's central bank and the Islamic Revolutionary Guard Corps, including its Qods Force. The same release put MEXC's daily transaction volume above $1 billion and its reserves at approximately $5 billion as of September 2026.

Frozen Deposits and Flagged Accounts

The restrictions reach well beyond the two platforms' direct corridors. A transfer between venues completes on-chain the moment it is broadcast, but the receiving exchange decides whether the balance ever becomes usable, and Binance has made clear that MEXC-linked deposits will sit in review before anything credits to an account. The exchange also stressed that its action does not amount to a global shutdown of MEXC withdrawals: the constraints apply only to transfers routed through Binance involving the named entities. MEXC rejected the allegations in a November 7 statement, saying its trading services remained operational and customer assets were secure, and that it was reviewing the findings with legal and compliance teams while running an independent examination of its anti-money laundering and sanctions controls. Chief executive Vugar Usi later acknowledged elevated withdrawal volumes but said deposits and withdrawals were continuing normally. Binance is not acting alone. According to crypto.news, OKX chief executive Star Xu warned customers against transferring funds directly from MEXC, saying deposits tied to affected platforms could be frozen and users might face further investigations under enhanced checks. Pressure on MEXC had been building for months. In October the exchange said it would discontinue services for customers in Russia and Belarus, giving affected users individual instructions for closing positions and withdrawing assets, with no common deadline announced. In May it restricted selected futures trading pairs for users in Russia, Ukraine, Armenia and Belarus, blocking new positions in the affected contracts. In July it appointed Robert MacDonald as chief compliance officer and began a collaboration with LSEG Risk Intelligence to use World-Check screening tools. The October service announcement named no specific regulatory order as the reason for the withdrawal from the two countries. FinCEN's measure takes effect 30 days after publication in the Federal Register, giving covered US institutions a defined window to sever their own links.

A New Counterparty Test for Exchanges

The Treasury press release is the document that matters here: it records a venue handling more than $1 billion in daily transactions and holding about $5 billion in reserves as of September 2026, a scale that explains why peer exchanges are not waiting for the Federal Register clock to run. COINOTAG's reading is that US designations now propagate into inter-exchange transfer policy within days, regardless of where either platform is domiciled, and that on-chain finality no longer guarantees usable funds at the destination. Users with balances split across venues may shift toward self-custody, where an HD wallet under their own control sits outside any exchange's review queue, while the 30-day window defines how fast the rest of the market lines up.
