South Korea's benchmark stock index endured a volatile session Thursday, lurching between heavy losses and partial rebounds as sustained tensions in the Middle East continued to unsettle global financial markets.

The KOSPI opened down 221.20 points, or 2.86 percent, at 7,509.62. The index deepened its losses in early trading, sinking as low as 7,394.46 — a decline of 4.35 percent — before recovering some ground. By late morning, the index stood at approximately 7,561, representing a loss of around 2.20 percent on the day.

The tech-heavy KOSDAQ composite also fell at the open, dropping 14.46 points, or 1.52 percent, to 937.17. The South Korean won weakened against the U.S. dollar, adding currency pressure to an already stressed trading environment.

Segye Ilbo characterised the day's trading as erratic and directionless, noting the repeated reversals between gains and losses as investors struggled to find firm footing. KBS World's public broadcaster focused on the factual breadth of the downturn, highlighting that the pressure extended across both the large-cap and technology-focused indexes.

The persistent uncertainty stemming from ongoing Middle East developments has been cited as a key driver of the risk-off sentiment gripping Asian equity markets. Investors have grown wary of potential disruptions to energy supply chains and broader geopolitical stability, factors that typically prompt capital to flee higher-risk assets.

South Korea's equity markets are particularly sensitive to external shocks given the country's heavy reliance on exports and energy imports. A weaker won compounds concerns by raising import costs, especially for oil, which South Korea purchases almost entirely from abroad.

It remained unclear as of late morning whether the partial recovery would hold into the afternoon session. Analysts were watching whether the KOSPI could stabilise above the 7,500 level, which has taken on psychological significance during the selloff.

Further direction for the market was expected to hinge on developments in the Middle East and any signals from global central banks or commodity markets. Until the geopolitical picture clarifies, traders said, wide intraday swings were likely to persist.
