The dollar-won exchange rate fell below 1,500 won on July 8 for the first time in 40 days, while stablecoin prices on Korean cryptocurrency exchanges showed a decline one day earlier on July 7. The exchange rate reached an intraday low of 1,498.10 won, the lowest level since the May 29 intraday low of 1,494.90 won. Industry experts attribute the stablecoin price movement to retail investors reacting quickly to market news, particularly regarding SK Hynix ADR listing and dollar supply expansion, rather than the crypto market predicting forex rate changes. The phenomenon highlights the structural differences between Korea's 24-hour cryptocurrency market dominated by retail investors and the traditional foreign exchange market, where corporate crypto investment remains prohibited and institutional market makers are absent.
Stablecoin Prices Fall Below 1,500 Won Ahead of Forex Market
Tether (USDT) on Upbit fell below the 1,500 won level at approximately 8 PM on July 7, one day before the forex market showed similar movement. According to Upbit Data Lab, USDT briefly recovered above 1,500 won at around 9 AM on July 8 but subsequently dropped to 1,490 won, declining nearly 10 won. Circle (USDC), the second-largest stablecoin by global market share, exhibited similar price patterns on both Upbit and Bithumb exchanges.
Upbit Premium Index Narrows to -0.96% During Rate Decline
The price gap between domestic and overseas stablecoin prices narrowed during the decline. The Upbit Premium Index, which measures the difference between CoinMarketCap global prices and Upbit prices, showed that the reverse premium for both coins typically exceeded 1% over the previous week. During the period when USDT and USDC traded below 1,500 won, the gap narrowed to -0.96%, indicating domestic prices more closely reflected the exchange rate decline. Reverse kimchi premium refers to the phenomenon where cryptocurrency prices on domestic exchanges trade lower than overseas prices, manifesting in stablecoins as domestic trading prices forming below the dollar-won exchange rate.
Experts Cite Retail Investor Reactions Over Market Prediction Theory
Kim Min-seung, head of Korbit Research Center, stated that determining whether stablecoins predict exchange rates remains difficult to generalize due to significant variations depending on market conditions. Kim attributed the recent decline to retail investors responding rapidly to market news, explaining that "retail investors react sensitively to news, so they may have immediately reflected the news of expanded dollar supply following SK Hynix ADR listing in prices." Kim added that "the occurrence of reverse premium is also interpreted as a signal that selling pressure was strong in the domestic cryptocurrency market."
Korean Crypto Market Structural Limitations Affect Price Dynamics
The retail-dominated structure of the Korean won market stems from structural constraints. Corporate cryptocurrency investment is not yet permitted, resulting in an absence of institutional investors to provide market making. Additionally, no direct market exists for exchanging dollar stablecoins with actual dollars, making arbitrage trading to narrow exchange rate gaps difficult. Kim noted that "because institutional investors cannot make markets, there have been several cases where cryptocurrency prices such as Tether surged when events occurred," adding that "while it reflects individual investor sentiment well, it is difficult to view the movement as something that can be explained by a single formula or theory."
