Until 8:39 on the same day, this unit announced the postponement of trading orders to the public and this information was only published on the website of the unit.

At the press conference on the afternoon of October 1, Hiroki Kawai, CEO in charge of securities transactions The Tokyo Stock Exchange explained that, if we try to quickly get the stock exchange back to the same day, it will not be able to conduct trading smoothly and steadily, “so we think it’s best to reopen in.

Providing information, even only a part of the assessed information, is essential and helps investors to better judge when the transaction is done online again. However, the Tokyo Stock Exchange did not give any specific explanation to the public until the press conference held at 4:30 p.m. on October 1, citing unclear information about dislike. well suited.

Meanwhile, in the midst of the incident, the Tokyo Stock Exchange was still in contact with stockbrokers and exchanged information.

And Taro Kono, Japan’s Minister of Public Administration Reform, replied to the press: “With digitization and online transaction functions, convenience and security are two sides of the same issue.” “If you cannot guarantee 100% security, then you need to find ways to improve your resilience,” added Taro Kono.

The “floor collapse” has damaged investors’ confidence in the Tokyo Stock Exchange in the context that Japan is trying to attract foreign investors and its ambition to become an international financial center. Analysts say that any attempt to attract investors into the market will need the support of a stable trading system.
