When Genius Failed: The Rise and Fall of Long-Term Capital Management

Roger Lowenstein details the rapid ascent and systemic collapse of Long-Term Capital Management, a hedge fund led by John Meriwether and a team of Nobel-winning economists. The narrative focuses on the firm’s reliance on complex mathematical models and convergence trades that exploited tiny price discrepancies in global bond markets. While the fund initially saw massive returns through extreme leverage, Lowenstein explains how the 1998 Russian debt default triggered a liquidity crisis. This exposed the flaws in the partners’ risk management assumptions, necessitating a multi-billion dollar bailout coordinated by the Federal Reserve to prevent a global financial meltdown.

Professional traders, risk managers, and students of financial history read this book to analyze how intellectual overconfidence leads to catastrophic failure. It serves as a study on the limits of quantitative modeling and the dangers of ignoring tail risks in interconnected markets. Readers walk away with a precise understanding of the disconnect between theoretical market efficiency and the irrationality of human behavior during a panic. The book provides a practical warning about the risks inherent in high-leverage arbitrage and the fragility of the international banking system.

Outward-looking and clear-cut; a moderate read.
