The Hong Kong stock exchange halted trading in both the securities and derivatives markets on Monday due to approaching Typhoon Talim.
The Hong Kong Observatory said storm signal No. 8 would remain in force at least until 4 p.m. (0800 GMT)
According to the exchange’s arrangement, the morning trading session will be suspended if the typhoon signal remains at 8 or higher at 9 a.m. Hong Kong time (0100 GMT).
The stock market will be shut for the rest of the day if a typhoon signal 8 is still in place by noon.
The storm has not caused any major damage, although the Observatory has warned of possible flooding in some areas.
