The oil shock in Japan

midway through · 1973-01-24 → 1974-10-09, -37.40% over the whole period

What happened that day?

  • The Nikkei rose 4.42% to close at 4,165.23. No single trigger for the day could be pinned down
  • The low of this episode had come two sessions earlier, on 18 December
  • That autumn oil producers raised prices sharply and cut exports, and Japan was shaken hardest
  • A country that buys nearly all the oil it uses sees prices and corporate profits worsen together when input costs rise
  • Wide daily ranges near a low are ordinary. Neither buyers nor sellers can settle on a price
  • The episode fell 19.11% from the August high to the December low. The real bottom for this market came the following October
