Mainland stock exchanges plan to install bourse-wide "circuit breakers" to stop panic selling after botched official efforts to stop plunges in the volatile A-share market. Beijing is also preparing to deleverage the market, determined to rid it of the speculative funds that helped drive the recent boom-to-bust share cycle. Under the new plan, the Shanghai and Shenzhen stock exchanges will halt trading for 30 minutes when the CSI300 index that tracks the 300 biggest mainland-listed firms jumps or slumps 5 per cent in intraday trading. They will stop for the day if it soars or dives by 7 per cent, the exchanges said. The circuit breaker system also applies to CSI300 index futures at the China Financial Futures Exchange in Shanghai. The public will have until September 21 to give feedback on the idea.
