On September 9, the KOSPI index in South Korea experienced a dramatic drop of 5.72% at the start of trading amid surging international oil prices. The index fell to 5265.37, a decline of 319.50 points compared to its previous close. The decline was notable as major stocks such as Samsung Electronics, SK Hynix, and Hyundai Motors also posted substantial losses, with each falling over 7% in early trading.

The rise in oil prices, which have surpassed $100 per barrel and are nearing $110, has significantly destabilized the market. Brent crude futures saw a striking increase of 16.88%, reaching approximately $108.16 per barrel. The repercussions of these soaring oil prices are felt across various sectors, prompting the Korean Exchange to activate a 'selling sidecar' mechanism at 9:10 AM to temporarily halt program sell orders, reflecting the urgency of the situation in the financial markets.

Additionally, the exchange rate of the Korean won against the US dollar also showed a notable rise, with the won depreciating by 16.6 won to start at 1493.0 won. This combination of plummeting stock prices and a weakening currency indicates a troubling financial landscape for South Korea, likely influencing economic stability and investor confidence in the near future.
