Seoul: South Korean stocks closed lower Thursday amid escalating tensions in the Strait of Hormuz, which triggered extreme volatility in global oil prices. The local currency fell sharply against the greenback. The Korea Composite Stock Price Index (KOSPI) moved down 26.7 points, or 0.48 percent, to close at 5,583.25.

The International Energy Agency announced a plan to release oil reserves to address fluctuations in global oil prices, but investors stayed on the sidelines amid concerns the conflict could linger for a longer period. "Global crude prices have surpassed $90 (per barrel) again, with the stock market reflecting such tensions," said Lee Kyoung-min, a researcher at Daishin Securities. Lee noted that the South Korean stock market appears to be experiencing eased volatility after recent swings, adding that "(Seoul shares) have become less sensitive to geopolitical risks."
