Korean cryptocurrency exchanges are increasingly challenging the Financial Intelligence Unit (FIU) over its regulatory actions. The Seoul Administrative Court recently ruled in favor of Dunamu, operator of Upbit, overturning part of the FIU's suspension order due to unclear regulatory standards. Similarly, Bithumb successfully obtained a suspension of the FIU's enforcement actions, highlighting the exchanges' pushback against perceived overreach. The exchanges, supported by the industry association DAXA, are also contesting proposed amendments to the Specific Financial Information Act. These amendments would mandate automatic reporting of crypto transfers over 10 million KRW as suspicious, a move DAXA argues could overwhelm the anti-money laundering system. This ongoing legal and regulatory confrontation signals a shift in South Korea's approach to cryptocurrency regulation, as exchanges seek clearer and more sustainable regulatory frameworks.
