South Korean stocks experienced a significant downturn on Monday, with the KOSPI index dropping 2.6% and the KOSDAQ index plummeting 5% intraday. This decline marks the sharpest one-day drop since November 13, driven by deepening political turmoil following the failure of an impeachment motion against President Yoon Suk Yeol over the weekend. The political crisis has led to a 2.78% drop in the Seoul stock market, reaching its lowest level in over a year. While most Asian markets saw gains, South Korea's market woes stood out, with the Hang Seng index also experiencing weakness.
