The first bounce

early in it · 1990-10-01 → 1991-03-18, +34.25% over the whole period

What happened that day?

  • On 2 October 1990 the Nikkei 225 rose 13.24% in a single day
  • 1990 was the first year of the Japanese bubble unwinding, and the index had been sliding since January
  • Iraq's invasion of Kuwait in August sent oil prices up and deepened the fall — a direct hit for a country that imports all its oil
  • In early October, views that the Middle East would not go to the worst case spread and crude settled, producing a violent bounce
  • Government and financial institutions supporting the market played a part too
  • But it was only a bounce. The bubble's collapse had just begun, and the Nikkei fell for another 19 years
