Key Takeaway:
- South Korea plans 20% ownership cap for major shareholders of crypto exchanges.
- Exceptions up to 34% and staggered compliance under Digital Asset Basic Act.
- Industry and legal critics warn competitiveness, constitutional risks, and management instability.
South Korean regulators and lawmakers have agreed in principle to limit any major shareholder’s stake in domestic cryptocurrency exchanges to 20%, according to The Block. The move targets governance risk at platforms that would be licensed under the forthcoming Digital Asset Basic Act and is framed as a structural change rather than a short-term market intervention.
Key mechanics remain subject to enforcement decrees under the Digital Asset Basic Act, including a pathway for limited exceptions of up to 34% and staged compliance windows, around three years for larger exchanges and up to six years for smaller firms, as reported by Cointelegraph. The cap would function alongside existing fit-and-proper tests, shifting attention to ongoing ownership concentration and control.
Industry opposition has been immediate. The Digital Asset Exchange Alliance (DAXA), which represents Upbit (Dunamu), Bithumb, Coinone, Korbit, and Gopax, argues the ceiling could weaken competitiveness and dilute clear lines of responsibility for customer assets, as reported by CoinCentral. The group warns that Korea-only caps may disadvantage local platforms against offshore rivals that face no comparable equity limits.
Legal and academic voices have flagged constitutional and policy risks. As reported by The Korea Times, attorney Kim Hyo-bong questioned whether a blanket cap can satisfy the proportionality principle and warned abrupt dilution could push operators abroad. In the same coverage, Professor Kim Yoon-kyung noted that hard ownership ceilings for crypto exchanges are rare globally, and forced stake sales can fuel management instability.
The 20% ceiling would apply to major shareholders of licensed Korean crypto exchanges, with definitions and any aggregation of related-party holdings to be specified in enforcement decrees under the Digital Asset Basic Act, per prior legislative discussions reported above. In practice, operators and parent companies with concentrated control, such as those behind DAXA-member venues, would assess whether holdings must be reduced once the cap and transition rules are finalized.
Regulators have framed the policy as aligning crypto trading venues with governance norms used in traditional market infrastructures. According to Finance Magnates, FSC Chairman Lee Eog-weon linked the cap to preventing conflicts of interest and cited precedents from securities exchanges and alternative trading systems. “These platforms require governance structures befitting that status,” said Lee, underscoring the Financial Services Commission (FSC) view that exchanges function as quasi-public market rails.
Secondary effects could include changes to board control, strategic partnerships, and deal-making. Analysts cautioned that forced stake reductions might complicate mergers and acquisitions, citing scenarios around Naver–Dunamu and Mirae Asset–Korbit, and could spur capital flight if implementation proves disruptive, as reported by Seoul Economic Daily. Market outcomes will depend on final decree language, the length of grace periods, and whether limited exceptions are granted for operators that meet enhanced governance thresholds.
