Less than half an hour. That’s how long China’s stock markets were open before declines triggered automatic circuit breakers, shutting down trading for the day.
China’s stock exchanges closed at 9:59 a.m. local time, just 29 minutes after markets opened, as the CSI 300 Index fell more than 7 percent. Trading was halted for half that time after a 5 percent drop triggered an earlier suspension. China’s markets are normally open from 9:30 a.m. to 3 p.m., with a 90 minute break in the middle.
