South Korea's Crypto Enforcement: Fines Signal Bank-Style Compliance Mandate

South Korea's Financial Intelligence Unit (FIU) is moving forward with a sweeping enforcement campaign against major cryptocurrency exchanges, targeting violations of anti-money laundering (AML) regulations. The initiative, which began with inspections of platforms like Upbit, Bithumb, and Korbit, has resulted in significant penalties, including a 35.2 billion won ($24.35 million) fine against Upbit's operator, Dunamu, and a three-month suspension of key services. The FIU is now preparing similar sanctions for Korbit, Gopax, Bithumb, and Coinone, following a year-long review process that has uncovered systemic compliance failures.

The regulatory crackdown follows a structured "first-in, first-out" approach, with inspections conducted in sequence since August 2024. Dunamu, inspected first, became the benchmark for penalties, while Korbit and Gopax-next in line for enforcement-are expected to face sanctions soon. Bithumb and Coinone, inspected later in the year, may see delays due to additional scrutiny of Bithumb's order book system as reported by Blockonomi. Industry experts anticipate that fines will mirror those imposed on Dunamu, with financial penalties and operational restrictions likely to be applied across the board according to Coinpedia.

The FIU's actions are part of a broader effort to align the crypto sector with traditional financial regulations. South Korea has mandated strict KYC protocols and AML reporting for exchanges, with non-compliance attracting severe consequences, including fines up to five times illicit gains and potential jail time. The enforcement drive aims to stabilize the market ahead of planned expansions in crypto-linked financial products, while also addressing concerns about illicit finance. Offshore platforms like KuCoin have also faced scrutiny, with unregistered operations blocked earlier this year.

Regulators expect the majority of sanctions to be finalized by the first half of 2026, though delays in Bithumb's case could push its resolution further out. The timeline overlaps with South Korea's delayed crypto tax regime, slated for January 2027, and ongoing policy debates about balancing innovation with oversight. Analysts suggest the penalties could reshape the competitive landscape, potentially leading to temporary suspensions or license adjustments for non-compliant platforms.

The enforcement actions reflect a global trend of tightening crypto regulations, with South Korea joining jurisdictions like the U.S. and EU in prioritizing AML compliance. The FIU's approach, however, is notable for its aggressiveness, with fines and operational restrictions signaling a clear message: crypto exchanges must adhere to the same standards as traditional banks. As the sector braces for further scrutiny, the outcomes of these cases will likely set a precedent for regulatory expectations in 2026 and beyond.
