What happened that day?

  • 12 September 2001 — Nikkei 225 fell 6.63%. US markets were closed and Asia opened first
  • For those four days Asian markets played an unusual role
  • Normally they react to New York's close; this time there was no New York price to reference
  • Investors worldwide watched Tokyo and Seoul to estimate how the US would respond
  • The timing was especially hard for Japan, still not out of the long stagnation begun in 1990 and still carrying unresolved bank problems
  • Little capacity to absorb an external shock
  • Fell 32.96% from peak
