|Tokyo bourse hit by glitch in derivatives trading
The Tokyo Stock Exchange halted trading in derivatives including Topix futures and Japanese government bond futures for more than an hour on Tuesday morning, suffering a glitch for the second time in six months, Reuters reports.
Trading resumed at 10.55 am Tokyo time.
A Tokyo Stock Exchange spokeswoman said the exchange was still investigating the problem.
Trading in Nikkei futures was not affected because they are traded on the Osaka Securities Exchange.
The last time the Tokyo Stock Exchange was hit by a glitch was on Feb. 2 when cash-share trading was halted in the morning session. In that case, trading in some 240 shares and instruments was affected.
Tuesday's suspension was the biggest for derivatives trading since July 2008 and the first such incident for the derivatives trading system installed in October 2009, a spokesman for the Tokyo bourse said.
The latest glitch did not affect cash trading, with both the Nikkei average and the Topix up 0.6 percent after Tuesday's morning session.
