KOSPI falls below 7000 amid rising oil prices and US Treasury yields

KOSPI volatility US Treasury yields oil price surge semiconductor stocks AI bubble concerns

South Korean stock markets, specifically the KOSPI and KOSDAQ, have faced significant downward pressure due to rising international oil prices and surging US Treasury yields. The KOSPI dropped below the 7000 level, driven largely by declines in major semiconductor stocks such as Samsung Electronics and SK Hynix.

Global economic indicators have contributed to this volatility. US 10-year Treasury yields approached the 5% threshold, while WTI crude oil prices surpassed $100 per barrel amid geopolitical tensions in the Middle East. Additionally, the US August Producer Price Index (PPI) rose 5.4% year-on-year, exceeding market expectations and fueling inflation concerns.

The Bank of Korea identified several factors behind the heightened domestic market volatility, including heavy concentration in the semiconductor sector, foreign investor rebalancing, and the liquidation of leverage positions. Meanwhile, analysts at KB Securities have warned that if US 10-year yields trend above the low 5% range, it could serve as a signal for a potential collapse of the AI investment bubble.
