Bitcoin’s rebound has revived one of crypto’s most closely watched retail sentiment indicators. After climbing from around $62,000 to more than $81,000 over the past week, BTC has pushed the so-called kimchi premium back into positive territory. As of September 1, Bitcoin on Upbit, South Korea’s largest exchange, was trading roughly 1% higher than its dollar-denominated price on Binance, according to Bloomberg. This marked about a week of premium pricing, the longest stretch since early May. Bitcoin also rose 25% in August, its strongest monthly gain since November 2024, though it has since settled near $78,000 after briefly crossing $80,000.
The kimchi premium reflects the gap between South Korean BTC prices and global markets. It is seen as a gauge of retail risk appetite in Asia, because local demand can push prices above overseas venues. CryptoQuant noted that the Korea Premium flipped positive after its longest period of negative readings, adding that such shifts have “typically been followed by a positive trend.” Rachael Lucas, an analyst at BTC Markets, said Korean retail investors tend to buy aggressively during risk-on phases and that capital controls make the move appear as a price gap rather than arbitrage flow.
Still, some analysts are cautious. Markus Thielen of 10x Research said the premium has turned positive, but spot trading volumes have not increased to the same extent, making it too early to call Korean investors the main driver of Bitcoin’s recovery. Meanwhile, institutional access remains limited: South Korea still has no spot Bitcoin ETF, retail investors cannot buy foreign ETFs, and local companies cannot open exchange accounts to purchase BTC. CryptoQuant founder Ki Young Ju suggested the next stage of the cycle could be driven by institutional demand and ETFs outside the US, while Japan’s potential move toward Bitcoin ETFs by 2028 could offer a regional reference point.
