The South Korean stock market suffered one of its fastest declines in history this week, with the Kospi falling around 20% in two trading days, as geopolitical tensions have, for the moment, shattered what could be called a speculative bubble in popular AI-related names.
The rapid decline came after months of aggressive buying by retail investors that had sent Kospi, dominated by Samsung and SK Hynix, up nearly 180% in about 10 months.
The moment has drawn attention to activity in Korea’s crypto markets, where trading volumes have begun to rise again.
South Korea is one of the few markets where retail traders play a major role in both stocks and digital assets. Analysts have long noted that local traders often rotate between speculative markets, rather than abandoning risk assets entirely.
In November, a CoinDesk analysis outlined what was called the “Great Korean Pivot,” noting that trading volumes on domestic cryptocurrency exchanges fell as retail traders moved into tech stocks linked to artificial intelligence.
However, that stock rally has now stalled or reversed.
When one market cools, South Korean traders’ attention often shifts to another. This may be benefiting cryptocurrencies, which have seen bitcoin rise 7% in the last 24 hours to exceed $73,000. Ether (ETH), solana (SOL), and XRP (XRP) have risen similar amounts.
Retail signals remain subdued
While cryptocurrency trading volumes have increased, at least for the moment, the activity still does not resemble the frenetic 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. When domestic demand increases, bitcoin often trades at a notable premium in Korean won markets.
Currently, that premium remains modest, with data from CryptoQuant showing Korea’s premium index approaching 1%, well below levels seen during previous retail-driven rallies. However, there has been a modest rebound in retail confidence, as the kimchi premium had fallen into negative territory in mid-January.
