Which 1998 hedge fund collapse required a Federal Reserve-arranged rescue because of fears of broader market disruption?

The 1998 hedge fund collapse that required a Federal Reserve-arranged rescue because of fears of broader market disruption was Long-Term Capital Management.

Long-Term Capital Management, or LTCM, was a highly leveraged hedge fund founded in 1994. Its partners included prominent financiers and Nobel Prize-winning economists. The fund used complex strategies that depended on small price differences converging across markets.

Russia’s debt default in August 1998 produced severe market turmoil and caused many of LTCM’s positions to move against it. Because the fund had borrowed heavily and traded with numerous major financial institutions, its disorderly failure could have forced rapid asset sales and transmitted losses through the financial system.

The Federal Reserve Bank of New York organized a private-sector recapitalization in September 1998. The central bank did not directly bail out LTCM with public money; major creditor banks supplied the rescue funds and took control of the portfolio. The episode became a major warning about leverage, interconnected derivatives, and risks outside traditional bank balance sheets.
