Which 1998 hedge fund collapse prompted a Federal Reserve-facilitated rescue?

Long-Term Capital Management prompted a Federal Reserve-facilitated rescue in 1998.

Long-Term Capital Management, commonly called LTCM, was a highly leveraged hedge fund founded in 1994. Its partners included prominent traders and economists, including Nobel Prize-winning economists Myron Scholes and Robert C. Merton. The fund relied heavily on mathematical models and convergence trades that expected price relationships to return to normal.

The Russian financial crisis of 1998 disrupted those assumptions. Losses mounted, investors withdrew, and the fund's large positions threatened to create wider market instability. The Federal Reserve Bank of New York organized meetings that led major private-sector banks to provide a recapitalization; the Federal Reserve did not directly inject taxpayer funds.

LTCM's episode is associated with market-crash history because it demonstrated how leverage and interconnected counterparties could amplify a relatively concentrated failure. It is not the same event as the 2008 collapse, although later regulators and economists frequently cited it as a warning.
