Cryptocurrency transfers originating from MEXC face increased compliance scrutiny as exchanges respond to a U.S. Treasury order targeting $16 billion in alleged illicit financial activity. Cryptocurrency users have reported deposit delays, frozen transfers and additional compliance reviews at major exchanges, including OKX, Binance and Gate, following enforcement action by the U.S. Financial Crimes Enforcement Network (FinCEN) against MEXC Global. The complaints emerged after FinCEN issued a special measure order on November 6, 2026, seeking to cut MEXC off from the U.S. financial system over alleged involvement in sanctions evasion, money laundering and cybercrime-related transactions.
According to reports circulated by Wu Blockchain, customers transferring cryptocurrency from MEXC to other centralized exchanges encountered additional risk assessments, delayed deposit credits and refund reviews. However, the extent of the restrictions remains uncertain. Binance and Gate have not announced exchange-wide prohibitions on MEXC-related deposits, and the number of affected customers has not been established.
OKX Strengthens Compliance Controls Ahead of Regulatory Deadline
OKX founder and CEO Star Xu confirmed that the exchange had strengthened its compliance procedures following FinCEN’s announcement, warning customers against transferring funds directly from MEXC to OKX. Xu explained that OKX treats FinCEN special measures with caution comparable to financial sanctions, meaning transfers associated with affected platforms may be frozen while accounts undergo additional investigation. He acknowledged that legitimate customers could experience disruptions but said the exchange had implemented tighter controls before the regulatory restrictions formally became effective.
One customer reported that two USDT transfers, worth approximately $848.80 and $11.70, had been placed under review after being flagged as potentially originating from high-risk addresses. Separately, Bitget Wallet reportedly confirmed that its card top-up service would not accept funds identified as originating from MEXC. These developments reflect individual compliance measures rather than a coordinated prohibition across cryptocurrency exchanges.
Importantly, FinCEN’s order directly applies to covered U.S. financial institutions. It does not automatically require every international cryptocurrency exchange to freeze customer deposits associated with MEXC. The restrictions become effective 30 days after publication in the Federal Register. Nevertheless, exchanges can independently strengthen transaction monitoring and counterparty screening before the federal deadline.
FinCEN Alleges $16 Billion in Illicit Transactions
FinCEN’s action forms part of Operation Economic Outcast, a U.S. Treasury initiative targeting financial networks allegedly facilitating sanctions evasion. According to the regulator, MEXC processed approximately $16.7 billion in transactions connected to illicit activity between May 2021 and May 2026. The agency identified nearly $1.5 billion in direct and indirect exposure to Russian sanctions-evasion activity and approximately $1 billion in direct transactions involving more than 40 Iranian cryptocurrency exchanges.
FinCEN also identified approximately $22 million in transactions involving Iran’s sanctioned central bank and the Islamic Revolutionary Guard Corps, including its Qods Force. The order was issued under Section 9714 of the Combating Russian Money Laundering Act, which allows U.S. authorities to restrict financial institutions identified as presenting significant money-laundering concerns. MEXC rejected suggestions that its operations had been disrupted, stating that the platform continued operating normally and that customer assets remained secure.
The exchange said it was reviewing the order with its legal and compliance teams, engaging with relevant authorities and conducting an independent assessment of its anti-money-laundering and sanctions controls. For cryptocurrency customers, the immediate concern extends beyond MEXC itself. Transfers originating from exchanges facing regulatory scrutiny may encounter additional verification requirements elsewhere, even when the underlying transactions are legitimate. The situation illustrates how regulatory action against one trading platform can influence risk-management decisions across interconnected cryptocurrency markets before formal restrictions take effect.
