The collapse of LTCM. Debt and Leverage: Financial weapon of mass destruction.

LTCM lost its money through a combination of three critical, interconnected factors:

1. Extreme Financial Leverage (The Amplifier)

This was the core mechanism of their downfall. The firm took its $4 billion in investor capital and, through borrowing and derivatives, controlled a staggering $1.2 trillion in financial positions. This meant that even very small market moves were amplified into enormous gains or losses. As the text states, "with this kind of financial leverage even the most minute market move against you can wipe you out several times over."

2. A Key Triggering Event (The Catalyst)

The specific market shock that moved against LTCM was Russia's default on its bonds in 1998. LTCM owned many of these bonds. This was not just a loss on those specific bonds; it triggered a global "flight to quality." Investors abandoned riskier assets (like the ones LTCM was heavily invested in) and rushed into ultra-safe U.S. Treasuries. This caused the price gaps between different securities—which LTCM's models bet would narrow—to widen dramatically instead.

3. The Failure of Their Models (The Blind Spot)

LTCM's sophisticated mathematical models, designed by Nobel laureates, were based on historical data. These models failed to account for two critical realities:

• "Black Swan" Events: The models could not foresee an event as extreme and unprecedented (in their historical dataset) as a major sovereign default like Russia's.

• Liquidity Risk and Crowded Trades: The models advised "waiting out the storm," assuming they could hold positions until prices returned to "normal." However, when the crisis hit, everyone was trying to exit similar trades at the same time. This created a liquidity crisis—there were no buyers for LTCM's enormous, complex positions. Their attempt to sell only pushed prices further against them, creating a death spiral.

The Sequence of Collapse:

1. Leverage set the stage for catastrophic loss from a small market move.

2. Russia's default provided the unexpected shock that moved global markets against LTCM's concentrated bets.

3. Model failure led them to hold on as losses mounted, assuming normality would return.

4. Liquidity vanished when they finally tried to exit, locking in massive, irreversible losses that burned through their $4 billion capital in months.

In essence, LTCM lost its money because it used extreme leverage to make enormous, model-driven bets on market behavior, and those models catastrophically failed when a real-world crisis caused markets to behave in an "improbable" way while simultaneously eliminating their ability to escape their positions.
