Circuit Breakers for May 2009


The Exchange will implement the below circuit breaker (CB) trigger levels and trigger processes for May 2009, after the launch of the next generation system, scheduled on May 7th.

  1. CB Trigger Levels

    (in JPY)

    (Mini & Options Included)
    Initial CB Trigger Levels
    (also CB Expansion Amounts)
    Gold 100
    Silver 25.0
    Platinum 200
    Palladium 60
    Aluminum 10.0
    Gasoline 2,400
    Kerosene 2,400
    Crude Oil 2,400
    Rubber 10.0
  2.  Process Following a CB Trigger
    1. For the first, second and third CB trigger, the trading session will be halted for 5 minutes from the time of the trigger. Trading will then resume with an expanded CB.

      Example for Gold (figures are in JPY):
        * CB Trigger Level after First Trigger = 100 (initial trigger level) + 100 (expansion amount) = 200
        * CB Trigger Level after Second Trigger = 200 (previous trigger level) + 100 (expansion amount) = 300
        * CB Trigger Level after Third Trigger = 300 (previous trigger level) + 100 (expansion amount) = 400
    2. From the fourth CB trigger, trading will resume after a 5-minute halt, but the CB trigger level will not be expanded (for the gold example above, the CB trigger level will stay at JPY 400). However, when deemed necessary by the Exchange, the halt period and trigger level expansion may be modified.
