Bithumb has won temporary relief from one of the harshest sanctions ever imposed on a South Korean crypto exchange. On April 30, 2026, the Seoul Administrative Court accepted the exchange’s request for a stay of execution, effectively pausing a six-month partial business suspension ordered by South Korea’s Financial Intelligence Unit (FIU). As a result, Bithumb can continue full operations while its administrative lawsuit moves forward.
Court pauses record enforcement action
The FIU, South Korea’s anti-money laundering watchdog operating under the Financial Services Commission, imposed the sanction in March 2026. In addition to the suspension order, the regulator fined Bithumb 36.8 billion won, or roughly $24.6 million, over approximately 6.65 million compliance violations.
According to the case details, the alleged violations fell into two major categories. The first involved around 3.55 million failures in customer identity verification. The second concerned roughly 3.04 million cases in which Bithumb allegedly failed to block transactions involving unregistered virtual asset operators. Taken together, the penalties represented an unusually severe enforcement move against a won-based digital asset exchange.
The six-month suspension would have prevented new users from transferring external virtual assets onto the platform. Bithumb argued that the measure would do more than merely limit a portion of its business. During an April 23 hearing, the company said the restriction would undermine new customer acquisition and weaken platform operations, especially if South Korea’s institutional investor market opens further to crypto participation.
Bithumb remains fully operational during litigation
Bithumb filed its administrative lawsuit and injunction request on March 23, only days before the suspension had been scheduled to take effect on March 27. The court’s decision means the exchange will remain fully operational for now, rather than being forced to implement a partial shutdown while the legal dispute is still unresolved.
Following the ruling, Bithumb said it would continue to present its position faithfully throughout the remaining legal process. One notable point in the broader dispute is that the company has not yet paid the FIU fine, even though the regulator reportedly offered a 20% discount for prompt settlement more than four weeks earlier.
A broader pattern across South Korea’s major exchanges
The Bithumb decision did not emerge in isolation. It came only weeks after another important courtroom development involving Upbit operator Dunamu. On April 9, a court issued a favorable first-instance ruling for Upbit, noting that exchanges’ own compliance efforts could be relevant in situations where regulatory guidance had not been sufficiently clear. The FIU has since appealed that judgment.
Coinone is also under pressure. The exchange faces a 5.2 billion won fine and a partial business suspension tied to Know Your Customer violations, with its first court hearing scheduled for May 12. Among South Korea’s four major won-based exchanges—Upbit, Bithumb, Coinone, and Korbit—only Korbit has not challenged the FIU’s sanctions in court so far.
Why the ruling matters for Korea’s crypto regulatory framework
The emerging pattern of court interventions is raising deeper questions about the legal durability of the FIU’s sanctions framework. In multiple cases, judges have considered whether exchanges made self-directed efforts to improve compliance even when the regulatory rulebook was not entirely clear. That judicial emphasis appears to differ from the FIU’s enforcement approach, which, based on the reported cases, did not fully account for such efforts in its penalty calculations.
For the regulator, the Bithumb case was framed as a limited operational restriction with only partial impact on trading activity and relatively contained consequences for revenue. The court was not persuaded. By granting the stay, it signaled that the balance of harm and the legal basis for immediate enforcement deserved closer scrutiny before the sanction could take effect.
The ruling does not mean Bithumb has prevailed on the merits. The underlying case is still ongoing, and the FIU’s allegations remain serious in both scale and substance. But the court’s intervention gives Bithumb time, preserves business continuity, and adds to a growing list of challenges confronting South Korea’s crypto enforcement regime.
More broadly, the case highlights a central tension in the country’s digital asset market: regulators are pushing for strict AML and KYC standards, while courts are increasingly being asked to determine whether those standards were enforced with sufficient legal clarity and procedural balance. As similar disputes involving major exchanges continue, the outcomes could shape not only the liability of individual platforms but also the practical boundaries of crypto regulation in one of Asia’s most active won-based markets.
