The Tokyo Stock Exchange, one of the three largest stock exchanges in the world, has suffered a system failure and trading was suspended all day today.

◀ Report ▶

This is the Tokyo Stock Exchange this morning.

The name of each stock is floating in the market, but the market price is not displayed and all trading volumes are displayed as zero.

The Tokyo Stock Exchange stopped trading the 3,700 shares throughout the day due to a glitch in the trading system that occurred around 7 am.

Only the Osaka Futures Exchange, which uses a different system, traded normally, and the Nagoya, Fukuoka and Sapporo stock exchanges, which have the same system as Tokyo, also stopped.

Consequently, the Nikkei Stock Average and the Tokyo Securities Stock Index, the main indicators of the Japanese stock market, were not calculated.

The sudden suspension of transactions has caused great confusion and harm to both Japanese and foreign investors.

“We are very sorry that we were unable to trade all day, which created limited trading opportunities for investors.”

The Tokyo Stock Exchange said no external cyberattacks were confirmed and that a problem occurred due to a hardware failure of unknown cause and decided to suspend trading before opening.

“There was a problem in the delivery of price information and in the commercial monitoring business. It was not possible to accurately deliver price information such as stock prices.”

The Tokyo Stock Exchange was suspended for 3 hours due to a trading system problem in 2005, and the afternoon market was stopped due to system processing power issues in 2006, but this is the first time trading has been suspended. throughout the day.

Tokyo Exchange plans to reboot the entire system for a normal opening tomorrow, but it is not yet clear whether it will be restored.

Securities trading, which is the core infrastructure of the capital market, has stopped all day without warning, inevitably damaging the credibility of the Tokyo Stock Exchange, one of the top three stock exchanges in the world with market capitalization.
