A technical problem has stalled trading on the Japanese stock exchanges, including the popular Nikkei 225 index, for an entire day.

A statement from the Japan Exchange Group did not provide details of the nature of the breakdown and did not specify when trading would resume.

The Tokyo, Nagoya, Fukuoka and Sapporo exchanges were suspended on Thursday.

The closure comes after cyber attacks on the New Zealand stock exchange in August.

“Trading in all stocks on the Tokyo Stock Exchange will be suspended due to disruptions related to the provision of market information,” said a statement from the Japan Exchange Group.

The problem was the exchange’s first significant mistake since 2018 when some investment firms were unable to place orders due to a trading system problem.

The Nikkei 225 index contains the stocks of many of the largest Japanese companies, including Honda, Nissan, Hitachi and Canon.

Cyber ​​attacks

Many stock markets have experienced temporary disruptions in the past.

The New Zealand exchange was hit by cyber attacks in August, forcing it to stop trading within a week.

Over the past decade, tech-heavy Nasdaq, New York Stock Exchange, London Stock Exchange, Singapore Stock Exchange and Bombays Sensex have all faced technical glitches that delayed trading.

In 2017, a temporary market error caused the share price of several large technology companies on the Nasdaq to be incorrectly quoted at the same price.
