What happened that day?

  • 27 March 1980 — Nasdaq Composite fell 6.15%. The day is known as Silver Thursday, when the silver price collapsed in one session
  • A group of investors had bought silver with heavy borrowing and driven the price up
  • When exchanges changed the rules and interest rates rose, the position failed → covering the shortfall meant selling other assets
  • That's why equities shook. A large loss in one market forces sales in another to cover it
  • Different asset classes are connected through the same investors' balance sheets
  • Fell 24.91% from peak. This was also a period of high inflation and high interest rates
