What happened that day?

  • From the 29 December 1989 peak to the 10 March 2009 low the Nikkei 225 fell 81.87% — 4,725 trading days
  • Late-1980s Japan had land and stocks booming together. People joked that Tokyo real estate alone could buy the United States
  • Banks lent against land, the loans went back into land and shares, and the loop inflated the bubble
  • The Bank of Japan raised rates sharply from 1989 and the loop broke. When land prices turned, the collateral behind the loans went with them
  • Banks stuck with bad loans could not make new ones, so the recovery kept getting postponed. The stall lasted more than twenty years
  • The Nikkei passed its 1989 high again on 22 February 2024 — 34 years later
