The exchange said Thursday that the problem concerns the distribution of market information, though it is not elaborate. The issue also affects smaller Japanese stock exchanges in Nagoya, Fukuoka and Sapporo, which share a similar trading system to the TSE.
It is not clear when the exchange will resume operations, but the TSE said in a statement that the shutdown would continue during Thursday.
“The suspension is regrettable,” Katsunobu Kato, Japan’s chief cabinet secretary, told a news conference. He added that the country’s financial regulator has ordered the exchange and its operator, the Japan Exchange Group, to investigate the cause of the error.
When asked about the possibility of a cybertech, Kato said he “hasn’t heard of such information yet.”
Problems closed the only major exchange operating in Asia on Thursday. Other countries are celebrating public holidays, including mainland China, Hong Kong and South Korea. Markets in mainland China will be closed for several days for the Golden Week holiday.
September was not bright for the market. Wall Street key indices broke all records, breaking a five-month winning streak and marking the first down-month since March.
For the overall quarter, things were a little better: all three indexes reached higher levels, with stocks rising after unbelievable levels in the first three months of the year, in place of the second straight quarter.
