back to the old high on 1998-11-23

What happened that day?

  • From the 17 July 1998 peak to the 31 August low the S&P 500 fell 19.34% — 31 trading days
  • In August Russia said it could not pay its government debt. Sovereign defaults are rare, and the shock was large
  • The big loser was Long-Term Capital Management, a hedge fund famous for the Nobel laureates who built it
  • LTCM was investing with tens of times its own capital borrowed. If it went under, the banks that had lent to it were next in line
  • The Fed convened the major banks to take LTCM over and wind it down, then cut rates three times. That settled it
  • The old high returned on 23 November — three months
