Which 1998 hedge fund collapse intensified a worldwide market crisis after Russia’s debt default?

Long-Term Capital Management intensified the worldwide market crisis after Russia’s 1998 debt default. The highly leveraged hedge fund had been founded in 1994 by prominent investors and financial experts, including Nobel Prize-winning economists.

LTCM used complex arbitrage strategies that assumed price relationships would converge. Russia’s August 1998 default and the resulting flight from risk caused those relationships to move apart instead. Losses mounted, and counterparties became concerned that a disorderly liquidation could destabilize already stressed markets.

The Federal Reserve Bank of New York organized a private-sector rescue in September 1998. Fourteen banks and investment firms provided capital in exchange for control of the fund; the U.S. government did not directly inject bailout money. The arrangement allowed LTCM’s positions to be unwound gradually.

The episode became a major example of systemic risk from leverage and interconnected derivatives. It is not the same event as the collapse of Lehman Brothers in 2008, though both are frequently discussed in histories of financial contagion.
