Bithumb Shuts Down USDT Market Following Regulatory Concerns
South Korea’s prominent cryptocurrency exchange Bithumb has recently announced the closure of its USDT market. This development follows a detailed investigation by the Korea Financial Intelligence Unit (FIU) focused on compliance with anti-money laundering (AML) and Know Your Customer (KYC) regulations within the crypto sector.
Why Did Bithumb Shut Down Its USDT Market?
Effective November 28, 2025, the closure marks an end to Bithumb’s collaboration with Australia’s Stellar Exchange, launched just two months prior. The partnership had introduced shared order books, which aimed to increase liquidity and provide users with deeper market access. However, it also became a focal point of scrutiny from South Korean regulators.
Key concerns stemmed from the partnership’s potential to create loopholes in AML controls. The FIU’s investigation, ongoing since October 1, 2025, primarily examined whether the collaboration could enable certain users to bypass global AML standards, including the Travel Rule. This rule requires cryptocurrency service providers to collect and share transaction details to prevent illicit activities.
What Happens Next for Traders?
As part of the shutdown, all pending USDT market orders have been canceled. However, the 10 digital assets previously traded in the USDT market will remain available for trading in Korean Won (KRW). Bithumb also confirmed that deposit and withdrawal functions for these assets will remain accessible for users, minimizing disruption to traders.
API services related to the USDT market have been suspended, and the platform has assured users that updates on any reopening or technical improvements will be provided in due course.
Regulatory Pressure on the Crypto Industry
This development highlights the ongoing challenges cryptocurrency exchanges face when attempting to expand cross-border services in jurisdictions with stringent regulatory requirements. South Korea, which enforces strict guidelines under its Act on the Protection of Virtual Asset Users, places heavy emphasis on investor protection and robust compliance frameworks.
For Bithumb, the regulatory pressure grew after it was revealed that staff from BingX—a Singapore-based entity connected to Stellar Exchange—operated out of Bithumb’s Seoul headquarters. This raised questions about oversight and the implications of foreign partnerships on domestic soil.
Looking Ahead: A Stable Trading Environment?
In its official statement, Bithumb emphasized that the shutdown was part of its commitment to creating a safer and more advanced trading environment. However, industry sources indicate that the move was likely driven by regulatory demands rather than voluntary upgrades.
This case underscores the importance of comprehensive compliance strategies for exchanges aiming to maintain global operations. It serves as a reminder of the complexities involved in operating within a regulated financial ecosystem, particularly in regions prioritizing investor security and crime prevention.
