Binance blocks MEXC transfers as FinCEN action spreads

Binance has stopped processing transfers involving MEXC, its affiliates and related entities. A customer trying to send money from Binance to MEXC will have that withdrawal rejected.

Money moving the other way faces a different barrier. Deposits from the listed MEXC entities will be held while Binance checks them. The exchange said an account could face further limits or be removed from the platform after that review.

It is a sharp change for users who treated the two exchanges like different bank branches. Funds may still be theirs, but the route between the branches is no longer open.

The restrictions follow FinCEN’s decision to name MEXC a primary money laundering concern in connection with Russian illicit finance. The order bars U.S. financial institutions from processing fund transfers involving MEXC and takes effect 30 days after publication in the Federal Register.

FinCEN alleged that MEXC handled at least $16 billion in suspicious transactions from May 2021 through May 2026. It also alleged nearly $1.5 billion in direct and indirect exposure to Russian sanctions evasion and said the exchange’s anti-money-laundering controls were severely deficient.

Those are allegations, not a finding that every MEXC customer or every transfer was improper. But exchanges dealing with the funds have their own checks to make. That is why a regulatory order aimed at one platform can quickly affect access at another.

A review can turn what normally feels like a quick transfer into a wait for compliance checks.

For Binance, the issue is counterparty risk. In plain English, it is the risk of doing business with a party whose money flows may create legal or financial trouble. Blocking the outbound path and inspecting the inbound path reduces that exposure.

Binance listed 13 entities under the restriction, including MEXC Global Limited, MEXC Estonia OÜ and MEXC Singapore Pte Ltd. The breadth matters because exchange groups often operate through several companies in different places.

The response is not limited to Binance. OKX has also warned users against transfers to MEXC. That shows how a U.S. enforcement step can travel beyond the firms directly covered by the order.

MEXC remains a sizeable venue. It was ranked ninth among spot exchanges, with roughly $813 million in spot trading volume over 24 hours. Binance was first, with about $6.4 billion over the same period.

Scale does not make the transfer limits less disruptive. Customers who use more than one exchange may find that moving funds between platforms becomes harder when one venue is flagged by authorities.

These moves do not establish that the MEXC restrictions caused the declines, but they put the compliance news against a softer market backdrop.

The immediate point is less about a price chart than the plumbing behind it. When a large exchange closes a transfer route, the effect lands first on customer access and on the firms deciding which counterparties they can safely handle.
