South Korea’s stock market suffered one of its fastest falls in history this week, with the Kospi down around 20% in two trading days, as geopolitical tensions have currently burst what can be called a speculative bubble in popular AI-related names.
The rapid decline followed months of aggressive buying by retail investors that had sent the Kospi – dominated by Samsung and SK Hynix – higher by nearly 180% in about 10 months.
The timing has drawn attention to activity in Korea’s crypto markets, where trading volume has begun to pick up again.
South Korea is one of the few markets where retailers play a major role in both stocks and digital assets. Analysts have long observed that local traders often rotate between speculative markets rather than exit risk assets altogether.
In November, a CoinDesk analysis described what was dubbed the “Great Korean Pivot,” noting that trading volume on domestic crypto exchanges fell as retailers moved into tech stocks linked to artificial intelligence.
However, that share rise has now stalled or reversed.
When one market cools, South Korean traders’ attention often shifts to another. That might bode well for crypto, which has seen bitcoin rise 7% in the past 24 hours to over $73,000. Ether (ETH), solana (SOL) and XRP (XRP) are rising by similar amounts.
Retail signals remain moderate
While crypto trading volume has surged higher, at least for now, the activity does not resemble the crazy speculative surges seen in previous Korean market cycles.
A key metric is the Kimchi premium, which measures the difference between bitcoin prices on Korean exchanges and global markets. As domestic demand increases, bitcoin often trades at a noticeable premium in the Korean won markets.
This premium currently remains modest, with data from CryptoQuant showing the Korea Premium Index close to 1%, well below the level seen during previous retail-driven rallies. However, there is a modest uptick in retail sentiment as the Kimchi premium dipped into negative territory in mid-January.
