Crypto giant Binance cuts off MEXC after US labels it a money laundering hub

The world's largest cryptocurrency exchange, Binance, has abruptly halted all transactions involving rival platform MEXC. This follows a severe U.S. Treasury action where the Financial Crimes Enforcement Network (FinCEN) officially designated MEXC as a "primary money laundering concern." The order, issued under laws targeting Russian illicit finance, effectively cuts MEXC off from the U.S. financial system and pressures global partners to follow suit.

For crypto users and developers, the impact is immediate and tangible. Binance will reject any withdrawals headed to MEXC and will freeze and review any deposits coming from it, warning that accounts involved could be banned entirely. FinCEN's order alleges that MEXC processed a staggering $16 billion in suspicious transactions over five years, with $1.5 billion linked to evading Russian sanctions. This shows that regulatory crackdowns are now causing direct operational disruptions across the entire crypto ecosystem, forcing even major players to choose sides.
