Seoul — South Korean equities suffered their largest single-day decline in history as escalating conflict involving Iran rattled global financial markets and triggered heavy selling across Asian stocks. The benchmark KOSPI index plunged 12.06%, marking the biggest drop in its 46-year history.
The sharp fall wiped out hundreds of billions of dollars in market value and sent South Korea’s currency, the won, to its lowest level in nearly two decades amid growing fears that the Middle East conflict could disrupt energy supplies.
Middle East Conflict Jolts Global Markets
The market turmoil follows continued military strikes on Iran by the United States and Israel, with Tehran launching retaliatory actions across the Gulf region. The conflict has expanded to nearby areas, including Lebanon, increasing geopolitical uncertainty and pushing oil prices higher.
Global investors reacted quickly to the escalating tensions, fearing supply disruptions in one of the world’s most critical energy regions. Oil-dependent economies in Asia were seen as particularly vulnerable to rising energy prices.
South Korea Hit Hardest in Asia
Among Asian markets, South Korea experienced the most severe losses due to its heavy reliance on Middle Eastern energy imports. Around 70% of South Korea’s crude oil imports originate from the Middle East, making the country especially sensitive to supply disruptions in the region.
South Korea is also the world’s fourth-largest oil buyer, meaning any sustained conflict affecting shipping routes or production could significantly impact the country’s industrial economy and export-driven sectors.
Analysts noted that Korean stocks had been one of Asia’s best-performing markets over the past year, which made them particularly vulnerable to a rapid reversal once investor sentiment shifted.
Trading Halted as Market Plunge Accelerates
During Wednesday’s trading session, the KOSPI dropped 698.37 points to close at 5,093.54, briefly falling as much as 12.65% earlier in the day. The sudden collapse triggered circuit breakers on the exchange, halting trading for 20 minutes in an attempt to stabilize the market.
Additional trading curbs were also activated as program trading intensified selling pressure. Despite these measures, the market continued to slide as investors rushed to exit positions amid the geopolitical uncertainty.
Growing Concerns Over Energy and Economic Impact
The sharp market reaction reflects broader concerns that prolonged conflict in the Middle East could disrupt global oil flows and slow economic growth in energy-importing economies.
For South Korea, higher energy costs could strain manufacturing industries, weaken exports and add inflationary pressure at a time when global markets are already facing volatility.
Investors and policymakers are now closely watching developments in the region, as further escalation could continue to drive instability across international financial markets.
