South Korean stocks suffered one of their fastest declines in history this week, with the Kospi index down about 20% in two sessions, as geopolitical tensions have shattered a so-called speculative bubble in popular artificial intelligence-related stocks.
Retail investors have been aggressively buying for months, causing the Korea Composite Stock Price Index, dominated by Samsung and SK Hynix, to rise nearly 180% in about 10 months, causing the stock price to fall rapidly.
The timing has drawn attention to activity in South Korea’s cryptocurrency market, where trading volumes have begun to climb again.
South Korea is one of the few markets where retail traders play a significant role in both stocks and digital assets. Analysts have long observed that local traders often rotate between speculative markets rather than exit risk assets entirely.
In November, a CoinDesk analysis described the so-called “South Korea Great Pivot,” noting that trading volumes on domestic cryptocurrency exchanges fell as retail traders turned to artificial intelligence-related technology stocks.
However, the stock market rally has now stalled or reversed.
When one market cools, Korean traders’ attention often shifts to another. This may be good for cryptocurrencies, with Bitcoin rising 7% in the past 24 hours to over $73,000. Ethereum (ETH), solana (SOL) and XRP (XRP) posted similar gains.
Retail signals remain mild
While cryptocurrency trading volumes have risen, activity, at least for now, has not resembled the wild speculative surge seen in earlier South Korean market cycles.
One key metric is the kimchi premium, which measures the difference between Bitcoin prices on Korean exchanges and global markets. When domestic demand surges, Bitcoin often trades at a significant premium on the South Korean won market.
The premium is still modest, with data from CryptoQuant showing the South Korean premium index is close to 1%, well below levels seen during previous retail-driven rallies. However, retail sentiment picked up slightly as the pickle premium fell into negative territory in mid-January.
