What happened that day?

  • From the 5 January 1970 peak to the 26 May low the S&P 500 fell 25.86% — 99 trading days
  • Vietnam War spending and expanding social programmes through the 1960s had pushed inflation up
  • The Fed tightened credit to contain it, and companies found short-term funding hard to get
  • That year the big railroad Penn Central failed for want of funding — the largest US corporate bankruptcy up to that point
  • It confirmed that when the plumbing of credit blocks, even healthy companies are at risk, and the fear grew
  • The Fed released funds to put out the immediate fire and things settled. The old high returned on 19 January 1971
