- Market Plunge: South Korea's KOSPI index fell nearly 9% on Monday, triggering circuit breakers as the market reacted sharply to robust U.S. jobs data that heightened Federal Reserve rate hike expectations, leading to a significant selloff in tech stocks, particularly with Samsung Electronics and SK Hynix dropping over 10% each.
- Chip Sector Impact: As key drivers of the KOSPI index, Samsung and SK Hynix saw their market capitalizations surge by over 150% and 200% respectively this year, but the recent selloff has led to substantial price corrections, highlighting the market's over-reliance on tech stocks for growth.
- Forex Market Volatility: The won appreciated by 0.7% to 1,548.9 against the dollar, rebounding from Friday's low of 1,615.0, reflecting authorities' firm stance against speculative trading, although officials warned that continued foreign selling of local stocks could exert further pressure on the won.
- Presidential Market Confidence: In a press conference marking his first year in office, President Lee Jae Myung stated that the market is still undervalued and described the current exchange rate as temporary and abnormal, emphasizing that foreign selling is a primary factor affecting the won, indicating government confidence in the market and future policy support.
