South Korean regulators have moved against Bithumb over alleged anti-money laundering failures. The Financial Intelligence Unit issued a preliminary notice that proposes a six-month partial business suspension. However, the measure would limit only certain services for newly registered users if authorities confirm it.
Bithumb Receives Preliminary Sanction Notice From FIU
The Financial Services Commission’s Financial Intelligence Unit sent the notice under the Act on Reporting and Using Specified Financial Transaction Information. The FIU oversees anti-money laundering compliance for cryptocurrency firms operating in South Korea. Regulators said Bithumb continued transactions with overseas virtual asset businesses that lacked local registration.
Authorities also said the exchange failed to enforce certain Know Your Customer procedures. As a result, the FIU proposed a six-month partial suspension and disciplinary action against the chief executive. However, officials stated that the decision remains subject to review before final confirmation.
The proposed restriction would apply only to virtual asset transfers by newly registered users. Therefore, existing customers would still deposit and withdraw Korean won and cryptocurrencies and continue trading. Local media reported that the FIU plans to hold a sanctions deliberation committee later this month.
Officials will determine the final penalty during that review session. The FIU may adjust the scope or duration of the sanction after discussions. Until then, Bithumb continues normal operations for current users.
Regulators Tighten Oversight After Prior Enforcement Actions
South Korean authorities have increased oversight of digital asset platforms over the past year. The FIU previously imposed a three-month partial suspension on Dunamu, which operates Upbit. Regulators also fined Dunamu 35.2 billion won, or about $23.65 million, for compliance failures.
In a separate case, regulators fined Korbit 2.73 billion won and issued an institutional warning. Officials cited similar shortcomings in anti-money laundering controls. These enforcement actions reflect a pattern of stricter supervision of registered exchanges.
Founded in 2014, Bithumb ranks among South Korea’s largest cryptocurrency exchanges. CoinGecko data places it second in domestic trading volume behind Upbit. Along with Coinone and Korbit, it accounts for most trading activity among locally registered exchanges.
The latest action follows an operational error reported last month. Bithumb mistakenly distributed billions of dollars worth of bitcoin to users during that incident. After that event, the country’s financial watchdog increased its oversight of cryptocurrency market operations.
