# JPYC’s fourfold price spike puts Korean liquidity safeguards in focus Author: Hatice Ertaş Language: English Published: 2026-09-28T02:47:05+03:00 Updated: 2026-10-08T22:34:48+03:00 ![A yen token engraved JPYC beside a Korean won symbol against the Seoul skyline.](https://kriptometa.com/uploads/jpyc-de-katlik-fiyat-sapmasi-kore-de-likidite-cagrisi-4296_article.webp) ## Key takeaways - Industry calls reported on September 27 seek adequate circulation and liquidity alongside reserves for won stablecoins. - JPYC reached 37.6 won on Upbit on September 17, against an 8.81 won reference price in the exchange’s morning notice. - The issuer’s one-yen redemption value differs from a live exchange quote. The proposed safeguards are not an adopted regulatory decision. JPYC’s jump above four times its reference price on Upbit has sharpened calls for liquidity safeguards in South Korea’s won stablecoin framework. Industry voices say reserve backing alone cannot keep exchange prices in line. Liquidity is becoming a sharper issue in South Korea’s debate over won-backed stablecoins. [A September 27 report by News1](https://www.news1.kr/finance/blockchain-fintech/6300291) describes industry calls for adequate initial supply and continuous trading quotes alongside reserve requirements. The backdrop is JPYC’s sharp price deviation on Upbit ten days earlier. The episode adds a market-access question to the [stablecoin news agenda](https://kriptometa.com/en/news/stablecoin). An issuer holding assets for redemption does not mean tokens will be available at the expected price on every exchange at every moment. ## A one-yen token traded at a very different price JPYC reached 37.6 won on Upbit on September 17. The exchange had quoted a reference price of 8.81 won that morning, leaving the peak at more than four times that level. The yen-linked [stablecoin’s](https://kriptometa.com/en/glossary/stablecoin) design had not changed. Its exchange price had diverged. In its [September 18 company announcement](https://prtimes.jp/main/html/rd/p/000000331.000054018.html), JPYC said each token was redeemable for one yen and described bank deposits and Japanese government bonds as its backing assets. The company also reported cumulative issuance above 10 billion yen. That total is neither the amount currently in circulation nor the number of tokens available for sale on Upbit. JPYC chief executive Noritaka Okabe addressed the listing excitement on X on September 17, the day of the price move: > “Listing on an exchange does not raise a stablecoin’s value.” Noritaka Okabe — translated from his September 17 X post [JPYC chief executive Noritaka Okabe’s post about listing and price](https://x.com/noritaka_okabe/status/2100431231167177014) His point was that a listing does not change the one-yen target. The exchange quote moving away from that target is an upward example of a [depeg](https://kriptometa.com/en/glossary/depeg): buyers pay more for the token while its redemption value with the issuer stays the same. ## Listing restrictions did not prevent the gap [Upbit’s listing notice](https://www.upbit.com/service_center/notice?id=1580532257) already restricted trading to limit orders for roughly the first two hours. It also said the opening could be delayed if sufficient liquidity was unavailable. The price deviation therefore occurred despite launch restrictions, rather than in a market with no initial controls. **A limit order is not a peg guarantee.** It sets the highest price a buyer will accept; it does not ensure execution at the token’s reference value. Paying a premium on an exchange does not oblige the issuer to redeem that premium. The Korean calls bring initial circulation, issuance and redemption channels into the same discussion. Disclosure of price deviations is also among the suggestions. These are industry proposals, not newly adopted regulatory requirements. For a business accepting tokens as payment, the practical question is how much cash a sale will deliver. That is why [stablecoin reserves, redemption access and exit liquidity](https://kriptometa.com/en/stablecoin-risks-checklist) need separate checks. In the JPYC episode, a balance valued at the exchange quote could look very different from the yen available through issuer redemption, even though both calculations concerned the same token.
