South Korea’s cryptocurrency exchange Bithumb may face a partial business suspension of up to six months after regulators raised concerns about its anti money laundering controls and customer verification procedures. The move comes as authorities tighten oversight of the country’s rapidly growing digital asset industry.
According to local media reports, South Korea’s Financial Intelligence Unit has issued a preliminary notice of sanctions against Bithumb for alleged violations under the Act on Reporting and Using Specified Financial Transaction Information. The exchange is currently the second largest crypto trading platform in the country by trading volume.
Regulatory Notice and Possible Suspension
The Financial Intelligence Unit has warned Bithumb of a potential six month partial suspension related to shortcomings in its anti money laundering and know your customer compliance systems. Regulators believe the exchange may have failed to properly monitor certain transactions and maintain adequate customer due diligence standards.
The proposed suspension would not shut down the exchange entirely. Instead, it would limit specific services for new users. Reports indicate that new members could be restricted from transferring or withdrawing digital assets from the platform if the penalty is finalized.
Bithumb has stated that the notice represents only a preliminary step in the regulatory process. The company explained that the decision has not yet been finalized and could change following further review.
CEO Receives Reprimand Warning
Along with the potential business restrictions, regulators have also issued a reprimand warning to Bithumb’s chief executive officer. In South Korea’s regulatory system, such a warning is considered a serious administrative penalty.
A reprimand warning can carry long term professional consequences. It may restrict the executive’s ability to be reappointed to leadership roles within financial institutions or hold similar positions in the future.
Authorities are expected to review the matter in detail later in March before announcing any final sanctions.
Concerns Over Overseas Crypto Service Providers
One of the key issues raised by regulators involves Bithumb’s dealings with overseas virtual asset service providers that may not be registered under South Korean regulations. Authorities have increasingly focused on preventing local exchanges from interacting with unregulated foreign platforms that could expose the financial system to risks such as money laundering.
Investigators also cited gaps in the exchange’s customer verification processes. Proper KYC procedures require platforms to thoroughly identify and verify users in order to prevent financial crimes and illegal transfers.
These requirements have become stricter in recent years as governments worldwide attempt to bring cryptocurrency markets under tighter regulatory supervision.
Scrutiny Following Promotional Error
The regulatory pressure comes shortly after a major operational mistake linked to a Bithumb promotional campaign earlier this year.
During an event held on February 6, the exchange reportedly credited participants with 2,000 Bitcoin instead of 2,000 Korean won, which is roughly equivalent to $1.40. The error resulted in a total distribution of around 620,000 Bitcoin, which at the time was valued at approximately $43 billion.
The incident triggered criticism directed at the Financial Services Commission for failing to detect weaknesses in Bithumb’s internal systems earlier.
Although the error was eventually addressed, the situation intensified scrutiny over the exchange’s operational controls and internal risk management practices.
South Korea Tightens Crypto Enforcement
South Korean regulators have taken a tougher stance toward cryptocurrency platforms over the past year, particularly regarding anti money laundering compliance and customer verification rules.
In November 2025, the Financial Intelligence Unit imposed a three month partial suspension and a fine of 35.2 billion won, roughly $25 million, on Dunamu, the parent company of the crypto exchange Upbit. The penalty was issued over similar AML related concerns.
Another exchange, Korbit, was also penalized in December 2025 with a warning and a fine of 2.73 billion won, or about $1.9 million.
These actions highlight the government’s push to enforce stricter compliance standards across the digital asset industry. Regulators have made it clear that exchanges operating in the country must strengthen their monitoring systems and follow customer verification rules more closely.
For Bithumb, the final outcome will depend on the upcoming sanctions review scheduled later this month. Until then, the potential suspension remains under consideration as authorities evaluate the exchange’s response to the allegations.
