What happened that day?

  • From the high on 18 March 1991 to the low on 18 August 1992, the Nikkei fell 47.29% over 352 trading days
  • The 1990 collapse had been about share prices. This time land prices turned, which changed its nature
  • Japanese banks had lent against land. When the collateral fails, the loans behind it fail with it
  • Admitting the losses would have sunk the banks, so they were not admitted. Cleaning up was delayed for years
  • That delay is the skeleton of the twenty-year slump that followed. Postponing a problem means paying more for it later
  • The high it fell from was not regained until December 2020
