What happened that day?

  • 23 August 1990 — Nikkei 225 fell 5.84%, during the oil spike that followed Iraq's invasion of Kuwait earlier that month
  • Oil is a special variable for Japan. Importing nearly all its crude means a price rise feeds straight into production costs and the trade balance
  • The memory of two oil shocks in the 1970s was still present
  • The timing was bad. The bubble had already begun deflating, and the Bank of Japan was raising rates to contain inflation
  • Higher oil gave it another reason to raise them further
  • Fell 39.08% from peak — a deep decline in the first year of the bubble's collapse
