LTCM Crisis — August-October 1998
When a hedge fund nearly broke the financial system

The Fed's rate cuts and coordinated bailout prevented LTCM's levered positions from cascading into broader failures. This established the precedent of the 'Fed put' for systemic risk.
From the October 1998 low, the S&P 500 rallied 35% over the next 6 months. Investors who panicked out missed one of the sharpest recoveries in history.
LTCM's genius-level quants used 25:1 leverage. Their models were correct over time but the mark-to-market losses exceeded their capital. Leverage is the single greatest risk in investing.
Audit your portfolio for leverage in every form — margin, leveraged funds, positions financed by loans — and size it so a six-week 22% market drop cannot force liquidation; LTCM was right on the trade and still failed because mark-to-market losses arrived before the payoff.
