President of South Korea, Yoon Suk-yeol, issued an emergency martial law order on the evening of the 3rd, bringing a huge impact to the South Korean financial market. The issuance of the "emergency martial law" itself has had a negative impact on investor psychology, especially as foreign investors account for about thirty percent of the South Korean stock market. After the market opened today, foreign investors net sold more than 260 billion South Korean won, this phenomenon will accelerate the decline in South Korean stock prices. In order to deal with possible market instability factors after the declaration of martial law, the South Korean Ministry of Planning and Finance has prepared to maintain market stability by providing unlimited liquidity to the financial markets when necessary. This morning, the South Korean Financial Services Commission stated that the 10 trillion South Korean won stock market stability fund will be ready to be put into operation at any time.
