Nikkei 225 · November 7, 1997

The November it started breaking

-4.22%

single-day change vs previous close

Part of a longer stretch

When the banks themselves failed

midway through · 1996-06-26 → 1998-10-09, -43.18% over the whole period

What happened that day?

  • The Nikkei 225 fell 4.22% on the day
  • The currency crisis that began in Thailand that summer had spread across Asia. Hong Kong shares had already broken hard
  • Japanese banks were among the heaviest lenders into south-east Asia. As those loans soured, books that were already bad got worse
  • Japan's own problem was that bad property loans built up since 1990 had never been cleared
  • The land taken as collateral kept getting cheaper, and the banks kept deferring rather than writing the losses off
  • From the end of this month large financial firms failed one after another, and all that deferred arithmetic came due at once
