'8000피' 찍고 고꾸라진 코스피…불어난 빚투 '경고음'

KOSPI's record-high crash exposes systemic risks from rapid retail investor leverage, as margin trading hits all-time highs amid FOMO-driven buying. Global interest rate increases (US 10Y yields exceeding 5% for the first time since 2007) are simultaneously triggering foreign investor outflows, leaving inexperienced margin traders vulnerable to sharp corrections. This convergence of leveraged retail positioning and macro headwinds creates a critical inflection point with contagion risks beyond individual losses.
