- • JPYC, a yen-pegged stablecoin, spiked to 37.6 won from a reference value of approximately 8.8 won following its September 17 listing on Upbit, representing a distortion of more than four times its intended peg due to severe liquidity constraints.
- • Upbit data revealed that 21,219 investors purchased JPYC at prices exceeding 10% above reference value within five days of listing, accumulating approximately 259.9 billion won in losses or overvaluation, highlighting acute investor protection gaps.
- • Similar price distortions occurred in other stablecoin listings on the exchange, including PYUSD (1,760 won) and EURC (7,860 won), indicating a systemic liquidity issue affecting centralized exchange market structure across multiple digital assets.

Summary
South Korea's Financial Services Commission initiated a regulatory review on September 28 to evaluate whether formal market-making frameworks should be introduced for digital assets, prompted by significant price distortions in stablecoin listings on the country's largest cryptocurrency exchange, Upbit. The review follows the September 17 listing of JPYC, a yen-pegged stablecoin designed to maintain a 1:1 value ratio with the Japanese yen, which experienced severe dislocation due to inadequate liquidity on the exchange.
The JPYC price spike exposed critical market structure vulnerabilities. The stablecoin traded as high as 37.6 won compared to its reference value of approximately 8.8 won, representing a distortion exceeding 400% of intended peg value. Market data from Upbit documented that 21,219 investors purchased JPYC at prices more than 10% above reference value during the five-day period following listing, collectively accumulating approximately 259.9 billion won in overvaluation. The incident revealed thin liquidity conditions typical of newly listed digital assets on centralized exchanges, where limited order book depth permits small volumes to move prices dramatically.
The JPYC incident was not isolated. Concurrent price spikes in other stablecoin listings—including PYUSD trading at 1,760 won and EURC at 7,860 won—indicated a broader pattern of exchange liquidity insufficiency affecting multiple digital asset classes. These distortions raised material investor protection and market efficiency concerns that prompted regulatory attention.
FSC Director of Digital Finance Policy Yoo Young-jun stated that the regulator would review the necessity of market-making activities to enhance efficiency and stability within the digital asset market. However, the official clarification emphasized that this review does not constitute an immediate regulatory change; existing restrictions on crypto market-making remain in place pending further analysis. The potential framework changes may be addressed within the scope of South Korea's proposed Digital Asset Basic Act, which represents the country's broader regulatory modernization effort in the cryptocurrency sector.
