What happened that day?

  • August 9, 2001 — the Nikkei 225 fell 3.36% to 11,754.56. No single cause for the day could be pinned down
  • This was the day 12,000 broke — a level that had held all summer
  • The spring's reform hopes had cooled. Restructuring, people started to reckon, makes the economy worse before it makes it better
  • Bank shares took the worst of it: clearing bad loans eats capital, and the price said so
  • It was the second straight decline, the lowest close since July 30, and the seventh largest one-day fall of the year
  • From May 7 to September 17 the episode ran -34.59%
  • The low came in September
