South Korea's Financial Intelligence Unit (FIU) has issued a notice to cryptocurrency exchange Bithumb, highlighting compliance gaps in its Anti-Money Laundering (AML) and Know Your Customer (KYC) procedures. These deficiencies could lead to severe penalties, including substantial fines that might exceed the 35.2 billion KRW penalty previously imposed on competitor Upbit.
The core of the regulator's concern lies in Bithumb's inadequate customer due diligence, specifically omissions in identity verification and address verification processes. Furthermore, the exchange is suspected of engaging in transactions with overseas virtual asset service providers (VASPs) not registered within South Korea. These compliance loopholes not only heighten the risk of illicit fund flows but also violate the obligation to assess the regulatory status of counterparties. Analysts point out that such risk factors, when identified by regulators, typically trigger intensified scrutiny as they undermine control measures designed to detect and deter money laundering activities. The risk exposure is particularly amplified when dealing with unregistered counterparties, as domestic regulators cannot rely on the oversight of their respective jurisdictions.
Industry observers deem the alleged violations by Bithumb to be serious in nature. According to AML Network, the fines currently under consideration are substantial and could potentially surpass the previous record set by Upbit. Legal scholars suggest that the discussion of suspending parts of the exchange's license before a final decision strongly indicates the depth of the regulators' concerns. Park Ji-hoon, a financial law professor, commented via MEXC.com that license-based sanctions are akin to a "nuclear option," typically reserved for exchanges exhibiting systemic failures or intentional misconduct.

A six-month partial suspension of trading for Bithumb, if imposed, could have direct repercussions for its users. Certain business lines of the exchange would be restricted for the stipulated period, while others might continue to operate, with the exact scope to be determined by the final decision. During this time, users might face more stringent deposit reviews or service limitations, depending on the terms set by the regulators. The continuity of operations would hinge on the extent of the sanctioned activities as identified in the review. Any official notification would further clarify which services would be suspended and which would remain available.
The review process for these sanctions is proceeding as planned. Before any penalty measures take effect, a committee will assess the investigation findings, the proposed measures, and their proportionality, after which a final decision may be confirmed. Public details regarding potential appeal mechanisms have not yet been disclosed.
Both the FIU and the Financial Services Commission (FSC) will play significant roles in the sanction review committee's decision-making. The anticipated process from the preliminary notice to the final sanction involves: first, the issuance of a preliminary notice, followed by deliberation by the sanction review committee, and if deemed appropriate, the final implementation of sanctions. Measures currently under consideration include fines in the hundreds of billions of Korean won and a six-month partial suspension of trading.
