Which investment fund’s 1998 collapse required a major Federal Reserve-arranged rescue after Russia’s default?

Long-Term Capital Management required a Federal Reserve-arranged rescue after Russia’s 1998 default.

Long-Term Capital Management, or LTCM, was a highly leveraged hedge fund founded in 1994. Its partners included prominent traders and economists, including Nobel Prize-winning economists Robert Merton and Myron Scholes. The fund used complex models to pursue small pricing differences across markets.

Russia’s August 1998 debt default and ruble crisis disrupted the relationships on which LTCM’s trades depended. Investors abandoned risky assets, correlations changed, and the fund suffered enormous losses while its borrowed positions magnified the damage.

The Federal Reserve Bank of New York helped organize a private-sector recapitalization involving major financial institutions. The central bank did not directly bail out the fund with taxpayer money, but officials feared that an uncontrolled collapse could destabilize already stressed global markets. LTCM was eventually wound down, and its episode became a prominent warning about leverage, interconnectedness, and model risk.
