Long-Term Capital Management: The 1998 Lesson in Leverage

Long-Term Capital Management (LTCM) had one of the most impressive teams ever assembled in finance. Founded in 1994 by former Salomon Brothers bond trader John Meriwether, its partners included Myron Scholes and Robert Merton, who shared the 1997 Nobel Prize in economics. For its first few years, it delivered exceptional returns.

Then, in 1998, it lost most of its capital in a matter of months. Its positions were so large and interconnected that the Federal Reserve Bank of New York organised a rescue by major banks to prevent wider damage to financial markets. LTCM remains one of the clearest lessons in how leverage, liquidity and correlation can overwhelm even the smartest investors.

1. The Strategy

• Relative value and convergence trades. LTCM bet that small price differences between related securities, such as similar government bonds, would narrow over time.
• Small profits per trade. Each opportunity offered only a small expected gain.
• Enormous leverage. To turn small gains into large returns, LTCM borrowed heavily and used derivatives, building positions many times its capital.
• Sophisticated models estimated risk based on historical relationships between prices.

2. The Early Success

LTCM produced strong returns in its first years, attracting capital from wealthy investors and institutions and favourable financing from banks eager to do business with it.

3. What Went Wrong in 1998

• The Russian default. In August 1998, Russia defaulted on its domestic debt, triggering a global flight to safety.
• Spreads widened instead of narrowing. Investors rushed into the safest, most liquid assets, pushing prices further apart rather than together.
• Correlations jumped. Trades that were supposed to be unrelated all moved against LTCM at the same time.
• Liquidity vanished. LTCM's positions were so large that it could not exit without moving prices further against itself.
• Others copied its trades, so forced selling by many players amplified the losses.

LTCM lost billions of dollars in a few months, wiping out most of its capital.

4. The Rescue

Fearing that a disorderly collapse would damage the banks exposed to LTCM and disrupt markets, the New York Fed brought together major financial institutions in September 1998. A consortium of banks injected about $3.6 billion to take control of the fund and wind it down in an orderly way. No public money was used, but the episode raised debate about whether such interventions encourage risk-taking.

5. Lessons for Investors

• Leverage turns small errors into large losses. Modest adverse moves can be fatal when positions are highly leveraged.
• Models rely on history. In crises, relationships between assets can break down.
• Liquidity matters most when you need it. Large positions are hard to exit under stress.
• Crowded trades are dangerous. When many investors hold similar positions, exits become disorderly.
• Brilliant people are not immune. Track record and credentials do not remove structural risks.
• Counterparties need visibility, a lesson repeated in later episodes. See Archegos.

Frequently Asked Questions

What was LTCM?

A hedge fund founded in 1994 by John Meriwether, with Nobel-winning economists among its partners, specialising in highly leveraged relative value trades.

Why did LTCM fail?

After Russia's 1998 default, markets moved sharply against its leveraged positions, liquidity disappeared and its losses wiped out most of its capital.

Did taxpayers bail out LTCM?

No. The New York Fed organised a rescue funded by a consortium of private banks.

What is the main lesson?

That leverage, illiquidity and crowded trades can overwhelm even the most sophisticated models and investors.

The Bottom Line

LTCM showed that brilliance and sophisticated models cannot protect against excessive leverage and vanishing liquidity. Its lessons have been repeated in later crises, and remain essential for any investor who uses borrowed money or holds large, concentrated positions.
