1. Historical Context
Founded in 1994 by Wall Street legend John Meriwether, the LTCM founded had Myron Scholes and Robert Merton on its board, winners of the Nobel Prize in Economics for developing the famous Black-Scholes model for valuing financial options.
2. The Breakdown Event
LTCM used complex mathematical models to perform interest rate arbitration, detecting small temporary price anomalies between different global sovereign bonds. As these anomalies delivered minuscule returns, the fund became massively leveraged: with just $4. 7 billion of equity capital, it controlled positions of over $125 billion and derivatives worth over $1 trillion. In 1998, an unforeseen event not contemplated in the fund's probability models occurred: Russia defaulted on its sovereign debt and devalued the ruble. Instead of converging towards the prices estimated by the formulas, the world's bond markets went into general panic, resulting in massive losses to LTCM that consumed almost all of its capital within weeks.
3. Global Economic Impact
Faced with the possibility that the forced liquidation of LTCM derivatives would unleash a chain collapse of the large Wall Street firms, the New York Federal Reserve had to intervene urgently in September 1998 to coordinate a private rescue of 3. 6 billion contributed by 14 large banks.
Key Financial Lesson (Psychology of Money)
Mathematical models based on historical data cannot predict irrational human behavior or atypical extreme events (Black Swans). Financial risk theory often underestimates the possibility of extreme market correlations.
4. Practical Case or Real Life Example
The bankruptcy of cryptocurrency exchange FTX and its associated fund Alameda Research in 2022 demonstrated the same arrogance: relying on quantitative models and highly leveraged trades that ignored extreme liquidity risks.
