시장 맥락(Macro Context)

1. 미국 연준(Fed) 의사록 — 금리 인상 가능성 시사

The minutes from the U.S. Federal Reserve, released on May 20, showed that more policy committee members are open to the possibility of interest rate hikes. Some Fed officials expressed concern over the current state of financial markets, which is analyzed as one of the factors behind foreign selling pressure on the domestic stock market, hinting at a prolonged high-interest rate environment.

While expectations for expanded global AI infrastructure investment persist, the Japanese Nikkei index reportedly fell for 5 consecutive sessions as of May 20, breaking below the psychological support level of 60,000 yen. The selling pressure on AI and semiconductors continues in Japan, which is linked to the increased volatility of domestic semiconductor-related stocks.

3. 달러 환율 및 코스피 변동성 확대

Recent rollercoaster market conditions have continued, with the daily fluctuation range of the KOSPI index reaching up to 675 points. Critics point out that the concentration on large-cap stocks and the surge in retail-driven ETF trading are leading to structural increases in volatility.
