What happened that day?

  • On 19 March 1990 the Nikkei 225 fell 4.15%
  • The next day the Bank of Japan raised its discount rate again — the fifth increase since May 1989
  • The market read the move in advance and priced it a day early. Expectation sets the price, not the announcement
  • The reason for the hikes was land. Share prices alone might have been tolerated; land prices had escaped control
  • In this stretch the index was 28.04% below its peak
  • One more rise that August took the rate to six percent
