Korea Premium Index measures the percentage price difference between crypto asset prices on South Korean exchanges and their equivalents on global trading venues, capturing the degree to which Korean market participants are pricing assets at a premium or discount relative to the broader international market.
When the premium is positive and elevated - historically referred to as the "Kimchi Premium" - South Korean exchanges are pricing the asset above global markets, reflecting strong local buying demand that is unable to efficiently arbitrage due to South Korea's capital controls and regulatory restrictions on cross-border crypto flows. Sustained high premiums have historically signaled periods of intense Korean retail participation and speculative demand, frequently coinciding with late-stage bull market activity driven by retail momentum.
When the premium compresses or turns negative, Korean demand is cooling relative to global markets - either reflecting reduced local retail interest or broader market sentiment deterioration. Tracking the Korea Premium Index alongside global exchange flows and fund volume provides a geographically segmented view of retail sentiment, helping identify when regional demand surges are contributing to or diverging from broader market trends.
