TSE hit by system glitch

Jiji Press TOKYO (Jiji Press) — A system glitch hit the Tokyo Stock Exchange on Tuesday, making it unable for some brokerage firms to accept trading orders.

“We apologize for causing a tremendous impact on investors,” JPX Senior Executive Officer Ryusuke Yokoyama said at a press conference.

According to Japan Exchange Group Inc. , the operator of the leading stock market in the country, also known as JPX, a problem occurred at one of the four computer servers used to connect securities firms with the exchange’s trading system at around 7:30 a.m.

The server in question went down when it was hit by a flood of order data from securities firms, according to Yokoyama.

Trading on the TSE is expected to return to normal from Wednesday, he noted.

The TSE has already reported the glitch to the Financial Services Agency.

A number of brokerage houses, including major players Nomura Securities Co., Daiwa Securities Co. and SMBC Nikko Securities Inc., were unable to take trading orders normally, with some of the companies partially suspending order acceptance.
