What happened that day?

  • 8 October 1998 — Nikkei 225 fell 5.78%
  • In currency markets the yen was appreciating dramatically over just two days
  • The cause was the aftermath of Russia's default and the LTCM collapse
  • Positions funded by borrowed yen were being closed en masse, concentrating orders to buy yen back
  • For Japan the surge was unwelcome. The domestic economy was depressed by bad bank loans, and exports — the one part still holding up — were made harder by the exchange rate
  • Fell 23.02% from peak
  • The structure where a strengthening home currency is bad news for the home market recurs in Japan
