Bitcoin kimchi premium nears 2% as Korea tops $80,000
Cryptoquant’s Korea Premium Index hit 1.98% on May 7 as bitcoin trading on South Korean exchanges exceeded $80,000, the highest kimchi premium since late February.
Bitcoin prices on South Korean exchanges topped $80,000 on May 7, and Cryptoquant’s Korea Premium Index (KPI) registered a 1.98% kimchi premium, the highest reading since late February.
The KPI measures how bitcoin trades on South Korean platforms relative to a global volume-weighted average price. The gap reflects differences in local spot-market demand and the global market.
South Korea’s crypto market is affected by strict capital controls and residency-based know-your-customer rules, which limit cross-border flows and can allow price gaps between local exchanges and global benchmarks to persist.
Throughout 2025, the KPI showed a persistent premium on average, with a peak of 8.27% in October after bitcoin moved past its previous all-time high above $126,000. In 2026 the pattern has been uneven. In January, bitcoin traded more than 4% higher on South Korean platforms such as Bithumb and Upbit. By the first week of March the KPI recorded a 2.27% discount, reflecting lower relative demand on local exchanges.
March trading was dominated by discounts for much of the month, with a modest recovery around March 27–28 before slipping again. April returned mostly to premium territory, and the May 7 figure of 1.98% was the strongest reading since the day before the regional conflict began. By May 9 the KPI had eased to a 0.77% premium, showing the premium can shift quickly.
Major local exchanges, including Upbit and Bithumb, have shown pronounced swings between discounts and premiums within weeks. Observers point to volatility in South Korea’s broader markets, including sharp moves in the KOSPI and rising demand for AI hardware from Samsung Electronics and SK Hynix, as factors that can affect local risk appetite and capital flows and influence the kimchi premium.
The KPI provides a real-time indicator of how regional demand can diverge from the global market. Traders and investors monitoring South Korean platforms use the index to track short-term differences between local prices and global benchmarks.
