South Korea's cryptocurrency market has contracted significantly, with trading volumes now only 8% of the KOSPI stock market's activity as of May 2026. This marks a stark decline from December 2024, when crypto trading volumes were 323% of KOSPI levels. The downturn is attributed to a 71% drop in crypto trading volume across major exchanges and a 243% surge in KOSPI trading, driven by a semiconductor rally and supportive government measures. The Bitcoin Korea Premium, or "Kimchi Premium," has turned negative, indicating weaker domestic demand for Bitcoin compared to international markets. This shift reflects reduced buying pressure among Korean traders. Additionally, upcoming regulatory changes, including a 22% tax on virtual asset gains above 2.5 million won starting in 2027, are expected to further impact the market. These factors suggest a period of consolidation for South Korea's crypto sector unless new drivers emerge to boost local interest.
