Crypto Exchanges face 20% cap as S. Korea agrees on rules

What the 20% major-shareholder cap means for crypto exchanges

south korea is moving toward a South Korea 20% ownership cap for crypto exchanges, limiting any single major shareholder’s stake to one-fifth of an exchange’s equity. The goal is to disperse control and lower governance concentration risks.

For large platforms, the rule would require cap-table changes and could prompt restructuring at market leaders. According to FinanceFeeds (https://financefeeds.com/south-korea-proposes-20-ownership-cap-for-major-crypto-exchange-shareholders/), the government and the ruling party are discussing ownership limits for major exchange shareholders in Korea.

Definitions, transitional arrangements, and how equity versus control rights are treated remain under discussion. Final thresholds and compliance mechanics could still evolve during rulemaking.

Why South Korea is imposing ownership limits now

Policymakers frame the measure as aligning crypto exchanges with standards applied to critical financial infrastructure. The intent is to curb conflicts of interest and strengthen investor protection as retail participation has surged.

“As [crypto] exchanges are now officially recognised as part of the financial system, we must create a governance structure that befits their status,” said Lee Eok-won, chair of the Financial Services Commission, via DLNews (https://www.dlnews.com/articles/regulation/korean-regulators-bid-to-cap-shareholders-crypto-exchange-stakes//?utm_source=openai).

Officials are also weighing how to preserve accountability while dispersing ownership. The debate includes whether ownership caps, voting-right measures, or behavioral obligations best achieve the policy goals with minimal market disruption.

If enacted, exchanges with any single owner above 20% would need to adjust cap tables and control structures. Upbit, operated by Dunamu, would likely revisit ownership and governance to align with the threshold.

Bithumb, another major venue, could face similar workstreams wherever a single holding exceeds the cap. Board independence, risk oversight, and related-party transaction policies may be tightened to fit the new regime.

Short term, compliance planning would focus on ownership mapping, fit-and-proper checks for controlling parties, and documentation of internal controls. Medium term, shifts in voting dynamics could alter strategic decision-making and M&A pathways.

Compliance options and possible 34% exceptions

As reported by The Block (https://www.theblock.co/post/392169/south-korean-authorities-settle-ownership-limit), regulators and legislators have converged on a 20% ceiling for major shareholders in crypto exchanges amid pushback from the Digital Asset Exchange Alliance. Policy discussions have also referenced potential exceptions up to 34%, though criteria remain unsettled.

Upbit and Dunamu shareholding restructuring: feasible paths and hurdles

Feasible paths include staged secondary sales, private placements, or dilutive issuances to broaden ownership. Alternatives such as ring-fencing control rights or voting trusts may be explored, subject to the final text.

Seoul Economic Daily (https://en.sedaily.com/finance/2025/12/31/korea-mulls-capping-crypto-exchange-stakes-sparking-ma?utm_source=openai) cites attorney Park Sang-jin saying authorities could require reductions toward 15–20% with a multiyear grace period, and that non-compliance may trigger business restrictions. The outlet also reports Dunamu chair Song Chi-hyung holds about 25.5%, implying material adjustments if a 20% cap is finalized.

Digital Asset Exchange Alliance (DAXA) response and governance concerns

The association has warned that forced ownership reshaping could impede growth, deter investment, and unsettle confidence. It has also raised accountability concerns and argued for calibrated tools like voting-right limits over strict equity caps.
