The worst-ever start to a year for Chinese shares triggered a trading halt in more than $7 trillion of equities, futures and options, putting the nation’s new market circuit breakers to the test on their first day.

Trading was halted at about 1:34 p.m. local time on Monday after the CSI 300 Index dropped 7 percent. An earlier 15-minute suspension at the 5 percent level failed to stop the retreat, with shares extending losses as soon as the market re-opened. Traders said the halts took effect as anticipated without any major technical problems.
