The Tokyo Stock Exchange is suspended for a day due to a computer problem

October 1, 2020

The Tokyo Stock Exchange announced this Thursday that it will cease operations until Friday due to a computer failure, after having operated non-stop since 2005 when operations were suspended for a few hours.

The system failure occurred early this Thursday morning (9:00 a.m. local time) due to a problem with data transmission and the receipt of trade orders, as reported in a statement to the state agency Kyodo.

The Sapporo, Nagoya, and Fukuoka exchanges also had to cease operations as, unlike the normal Osaka exchange, they all use the same IT service as the Tokyo exchanges.

Operations were suspended due to irregularities in the Nikkei index, which is made up of the 225 most liquid stocks, and in the Topix, which includes Japanese companies in the so-called First Section. Amnbos tracks 3,700 companies.
