Tokyo Stock Exchange Group Inc. said a computer error Tuesday halted trading of Topix index futures, Japanese government bond futures and options trading for about 95 minutes, the second time in seven months a malfunction has forced a shutdown.
The failure lasted from about 9:20 a.m. to 10:55 a.m., the bourse operator said. Index shares were 20 percent below average for the time of day after the Topix and JGB futures were halted. Ten-year JGBs fell during the breakdown.
The exchange suffered its biggest disruption in six years on Feb. 2 as a glitch halted trading for 3½ hours in some of the country's biggest companies.
