In view of the Rubber market situation and in order to facilitate the exit of the market by market participants, from the start of today’s night session (4/21st 17:00 JST) and until the end of the day session on 4/30th, the initial CB trigger level in the Rubber market shall be +/- 20 yen from the settlement price and the expansion amount (when the CB is triggered) shall be 20 yen.
The Exchange will make a separate release on the Circuit Breakers for May 2010.
Process Following a CB Trigger
(a) For the first 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 level.
*CB Trigger Level after First Trigger = 20 (initial trigger level) + 20 (expansion amount) = 40 yen
(b) From the second CB trigger, trading will resume after a 5-minute halt, but the CB trigger level will not be expanded (the CB trigger level will stay at JPY 40). However, when deemed necessary by the Exchange, the halt period and trigger level expansion may be modified.
