Which 1998 hedge fund collapse threatened financial stability after Russia’s debt default and required a Federal Reserve-arranged rescue?

Long-Term Capital Management was the 1998 hedge fund whose collapse threatened financial stability after Russia’s debt default.

LTCM was founded in 1994 by traders and academics, including Nobel Prize-winning economists Myron Scholes and Robert C. Merton. It used highly leveraged mathematical trading strategies, believing that price relationships would converge toward historical patterns.

Russia’s August 1998 default and devaluation disrupted those assumptions. Investors rushed toward safer assets, correlations changed, and LTCM suffered enormous losses. Because major banks and dealers were exposed to the fund, the Federal Reserve Bank of New York organized a private-sector recapitalization in September 1998.

The Federal Reserve did not use taxpayer funds to rescue LTCM directly, and it did not formally manage the fund. The episode is often cited as a warning about leverage, crowded trades, and risks outside traditional banking. It also showed how a relatively small institution could threaten markets through its connections to major financial firms.
