KOSPI falls below 7000 as oil and US yields surge

KOSPI KOSDAQ US Treasury yields oil prices semiconductor stocks

South Korean stock markets experienced significant volatility as the KOSPI fell below the 7000 level, driven by rising international oil prices and surging US Treasury yields. The decline was led by major semiconductor stocks, including Samsung Electronics and SK Hynix, which faced heavy selling from both foreign and institutional investors.

Global economic pressures contributed to the downturn. US Producer Price Index (PPI) data showed a 5.4% year-on-year increase, fueling inflation concerns and increasing the likelihood of further interest rate hikes by the Federal Reserve. Additionally, crude oil prices surged, with WTI exceeding $100 per barrel due to geopolitical tensions in the Middle East.

The Bank of Korea noted that high market volatility in South Korea is exacerbated by a heavy concentration in the semiconductor sector, foreign portfolio rebalancing, and increased leverage through retail 'debt-investing' and leveraged ETFs. Analysts have warned that if US 10-year Treasury yields trend toward the 5% threshold, it could signal a broader risk to AI-related investment cycles.
