South Korea’s Financial Intelligence Unit (FIU) under the Financial Services Commission notified Bithumb of a preliminary six-month partial business suspension on March 10, 2026, following findings of anti-money laundering (AML) and customer-verification lapses. The notice—triggered by alleged transactions with unreported overseas virtual asset operators—targets new user crypto transfers, while existing users retain deposit, withdrawal and trading rights.
The FIU highlighted deficiencies in Bithumb’s Know Your Customer (KYC) procedures and oversight of cross-border transaction flows. Prosecutorial sources indicate that the exchange’s chief executive officer may face disciplinary measures, and the FIU will convene a sanctions review committee later this month to finalize disciplinary actions. Regulators may adjust penalties during the formal enforcement process, which grants Bithumb an opportunity to present counterarguments and remediation plans.
This action underscores tightening regulatory scrutiny across South Korean exchanges, following Dunamu (Upbit) and Korbit enforcement in late 2025. Dunamu received a three-month suspension and ₹35.2 billion fine, while Korbit faced warnings and a ₩2.73 billion penalty. Market observers view the Bithumb case as a test of the FIU’s resolve to enforce AML rules uniformly, with potential ripple effects for domestic and regional digital asset platforms.
Industry participants are monitoring the committee’s deliberations and potential sanctions range, which could include full withdrawal limits, deposit freezes, or structured fines. Bithumb’s compliance unit has signaled internal procedural overhauls, including enhanced transaction monitoring and strengthened due diligence protocols. The exchange is engaging external auditors and legal advisors to mitigate reputational and operational fallout.
Regulatory watchers anticipate the FIU’s final determination by late March. Meanwhile, competitor exchanges Coinone and GOPAX face parallel reviews. The evolving enforcement landscape in South Korea highlights broader global emphasis on AML compliance in crypto markets, pressuring platforms to balance customer experience with rigorous regulatory adherence or risk operational curtailment.
