Alarming Leverage Data in U.S. Equities

Behind the global AI bull market lies a massive buildup of leverage. U.S. stock market margin debt has surged to an all-time high of $1.4 trillion, indicating investors are participating at record borrowing levels. Meanwhile, assets under management of leveraged ETFs have doubled to $220 billion in just two months. In South Korea, the KOSPI index saw violent swings and triggered a circuit breaker due to high leverage and concentrated holdings, highlighting the fragility of derivatives markets.

Institutional Warnings

Both Barclays and Morgan Stanley have warned that highly leveraged derivatives could trigger a negative deleveraging spiral — price declines force leveraged positions to unwind, pushing prices lower and creating a vicious cycle that amplifies overall market losses. Investors should remain vigilant against this potential systemic risk.
