South Korea's stock market experienced a severe sell-off on Tuesday, prompting concerns that losses could spread into cryptocurrency markets. The Korea Exchange activated a five-minute trading halt after the KOSPI index fell 5%, the first such sidecar in nearly two months. Major components including Samsung and SK Hynix declined 5% and 6% respectively, with the index dropping more than 15% over five days.
Tom Lee warned on October 13 that the equity market decline could pressure digital assets through two channels: margin liquidations at brokerages and the fact that Korean investors hold significant cryptocurrency positions. "This major decline in Korean equities likely spilling into crypto," Lee stated, characterizing the near-term outlook as containing "short-term pain."
The concern centers on a common market dynamic: investors forced to sell assets to cover margin calls in equities may be pressured to liquidate other holdings, including cryptocurrencies, even without a crypto-specific trigger.
South Korean equity losses reached approximately $150 billion as the KOSPI fell 4.5% within minutes. The decline exceeded 6% overall, and Nasdaq 100 futures also fell 1% in overnight trading, suggesting the sell-off extended beyond South Korea.
Bitcoin declined to approximately $81,000 during the market turbulence before recovering toward $84,000. The broader market saw approximately $810 million in cryptocurrency positions liquidated within 24 hours, with roughly 85% of those liquidations affecting long positions. The wipeout impacted 173,611 traders.
Ethereum traded above $2,500 but remained 6% lower than levels from a week prior, while XRP bottomed near $1.31 and traded around $1.37, down approximately 3% in the preceding 24 hours.
