South Korea Considers Crypto Market Maker Rules After Stablecoin Surge
Regulators reassess liquidity frameworks following JPYC's 4x price deviation on Upbit.
1Stablecoin anomaly triggers scrutiny
JPYC, a yen-pegged stablecoin, traded at 4x its intended value on Upbit due to thin order books, exposing structural liquidity gaps. The 37.6 won peak versus 12 won opening price occurred within one hour on September 17, contradicting stablecoins' price-stability premise. This event forced South Korea's Financial Services Commission to confront long-deferred questions about crypto market infrastructure, particularly the absence of authorized market makers to maintain orderly trading.
2Regulatory dilemma surfaces
Current South Korean law lacks exemptions for crypto market-making under its market manipulation provisions, effectively banning liquidity providers. FSC's Yoo Young-joon acknowledged growing demands for discipline after retail losses from the JPYC surge. The Virtual Asset User Protection Act's blanket approach now faces scrutiny, as it prevents firms from offering continuous two-sided quotes - a standard practice in traditional finance and decentralized exchanges through automated market makers.
3Academic groundwork exists
KB Securities researcher Lee Min Jung's 2024 paper in Seoul Law Review previously argued for conditional market-making allowances as markets mature. Korbit Research Center's Yoonyoung Choi separately identified the lack of market-makers as causing Korea's persistent 'Kimchi premium' - where crypto trades higher domestically than globally. These studies provide intellectual foundation for reforms, suggesting liquidity solutions shouldn't be conflated with manipulation risks.
4Proposed solution's limits
Any market-making framework would primarily address order-book depth, not guarantee perfect peg stability. While it could prevent extreme deviations like JPYC's spike by ensuring resting liquidity, stablecoins would still fluctuate within bands. The FSC emphasizes that surveillance requirements for suspicious transactions would remain, with Financial Supervisory Service maintaining investigation powers. Market-making permissions would supplement, not replace, existing anti-manipulation controls.
5Implementation challenges
The FSC currently explores conceptual approval, not concrete timelines or pilots. Key design questions include defining acceptable market-making practices versus prohibited manipulation - such as distinguishing legitimate inventory management from wash trading. Success hinges on creating precise safeguards that reduce liquidity risk without creating new regulatory arbitrage opportunities, a balance global regulators also struggle with.
6Market structure implications
Reforms could reduce spreads and volatility for Korea's $20B+ crypto market, potentially attracting institutional participation. However, the JPYC incident shows even simple stablecoins face complex microstructure issues when liquidity fragments across exchanges. Any solution must account for Korea's unique dynamics, where domestic platforms dominate retail trading but lack sophisticated liquidity providers common elsewhere.
7Regional competitive dimension
As Japan and Singapore develop clearer crypto market-making rules, Korea risks falling behind in financial innovation. The FSC's deliberation comes as regional hubs compete to establish compliant digital asset frameworks. Successful reforms could position Korea as a leader in crypto market infrastructure while addressing retail protection concerns that have previously driven strict policies.
8Broader stablecoin lessons
The JPYC episode demonstrates how exchange-specific factors can override stablecoin pegs, independent of reserve adequacy. This highlights the need for holistic market design beyond just issuer oversight - including liquidity mechanisms, exchange risk controls, and clear arbitrage pathways. Korea's approach may set precedents for managing these interdependencies in regulated environments globally.
