Korea’s FSC floats crypto market-making review after JPYC spikes 12 KRW to 37.6 KRW
Officials signaled current manipulation rules can block liquidity providers, leaving new listings thin and disorderly.
South Korea’s Financial Services Commission said it is considering a digital-asset market-making system after JPYC, a yen-linked stablecoin, traded up to about four times its peg on Upbit. The move has refocused attention on how Korea’s manipulation rules can leave listing-day order books too thin to absorb retail flow without sharp dislocations.
JPYC’s 4x Upbit Spike Puts Korea’s Market-Structure Rules Back on the Table
Yoo Young-joon, director of digital finance policy at South Korea’s Financial Services Commission (FSC), said the regulator will review whether the market needs formal mechanisms such as market-making activity after JPYC’s listing-day dislocation on Upbit.
Upbit opened trading of JPYC on Sept. 17. The market opened at 12 Korean won per JPYC and reached 37.6 Korean won about one hour later. The spike was attributed to limited liquidity on Upbit.
Yoo framed the response as a stability and efficiency problem, not a token-specific drama. “We will also review the need to introduce systems such as market-making activities to increase the efficiency and stability of the digital asset landscape,” he said at a conference in Seoul on a Monday, with the exact date not specified in the available material.
He also tied the review to political pressure around outcomes for retail traders. “There were also criticisms that user losses occurred from the price surge after the JPYC listing, so demands for discipline in this area are expanding.” The size and distribution of those losses were not quantified.
Why the Virtual Asset User Protection Act Leaves Listings Thin
South Korea’s Virtual Asset User Protection Act includes market-manipulation provisions and does not contain an exemption for market making. In practice, that leaves professional liquidity provision in a gray zone and can deter firms from continuously quoting both sides of the book.
That matters most on listing day, when price discovery is forced through a shallow order book. Without a designated liquidity provider, spreads can gap, slippage becomes the tax, and early prints can become “false” reference prices that pull in momentum flow.
Stablecoins make the microstructure failure more visible. Traders expect a peg, or at least tight mean reversion around a reference value. When the first hour trades 12 KRW to 37.6 KRW, the market is not debating the peg mechanism. It is clearing an imbalance with too few counterparties.
The regulatory tension is straightforward. Market making can look like manipulation if the rulebook does not distinguish between bona fide quoting obligations and wash-style activity. A 2024 peer-reviewed Seoul Law Review paper by KB Securities researcher Lee Min Jung captured the conservative view: regulators had not allowed crypto market making because it could amount to market manipulation, and a carve-out could be considered only once the market becomes more stable.
The opposing camp argues the status quo already produces harm. A paper by Yoonyoung Choi of the Korbit Research Center said the domestic market has faced “serious liquidity problems” without a formal market maker system, contributing to price discrepancies and volatility. The paper cited the Kimchi premium as a symptom of structural inefficiency.
What a Market-Making Carve-Out Could Change for Spreads, Volatility, and Stablecoin Dislocations
A carve-out, if it arrives, is a market-structure change traders will feel in execution quality. Formal market makers with clear permissions and surveillance constraints can tighten spreads, reduce listing-day air pockets, and make arbitrage faster when a stablecoin prints away from its reference.
The immediate question is implementation path. The FSC has not said whether it would try to narrow what counts as manipulation through interpretive guidance under the Virtual Asset User Protection Act, or whether it would seek amendments or new provisions that explicitly permit regulated liquidity providers.
This discussion is also colliding with a larger legislative build. The FSC said in July it planned a consolidated Digital Asset Basic Act covering stablecoins and broader crypto-market rules, including requirements for digital asset businesses, exchanges, disclosures, and internal controls. Lawmakers had not settled key aspects, including rules for won-denominated stablecoin issuers.
Sequencing risk is real. Market-making rules could be bundled into the broader Digital Asset Basic Act timeline, or delayed by unresolved stablecoin policy debates. In the meantime, exchanges may have to self-help: tighter listing procedures, liquidity requirements, opening-auction mechanics, or stronger risk warnings for new pairs.
The cleanest real-time signal will be behavior, not headlines. If JPYC pricing on Korean venues normalizes versus expected yen-linked levels, that suggests the dislocation was primarily a launch-liquidity event. If it remains prone to outsized deviations, the market will keep pricing a structural liquidity discount into similar listings.
My Read: The FSC Is Treating JPYC as a Liquidity Incident, Not a Stablecoin Failure
The threshold that matters is whether the FSC creates a compliant path for continuous two-sided quoting, or just restates manipulation risk in softer language. Yoo’s comments and the explicit reference to user-loss criticism read like a market-structure response to a visible liquidity vacuum, not an indictment of JPYC’s peg design.
If the carve-out is delivered as enforceable guidance or legislation, listing-day prints like 12 KRW to 37.6 KRW should become harder to produce because the book is deeper by design, not by luck. That is when this stops being an Upbit incident and becomes a durable change in Korea’s execution regime.
