Tokyo Stock Exchange CEO quits over October 2020 shutdown

The head of the Tokyo Stock Exchange (TSE) has stepped down after accepting responsibility for an unprecedented daylong shutdown of one of the world’s biggest markets, the operator said on Monday, November 30.

A hardware glitch suspended transactions for a day on Tokyo’s two leading indexes last month, as well as smaller exchanges in other parts of Japan.

TSE president Koichiro Miyahara “has taken seriously his responsibility for the failure in the…trading system,” the Japan Exchange Group (JPX), which operates TSE, said in a statement.

Miyahara “has requested to resign from his position as president and CEO of TSE and all other held positions within the Group, effective on November 30,” it said.

The CEO of JPX, Akira Kiyota, will temporarily take over the position with a 50% pay cut for 4 months, the statement said.

JPX and TSE were also served a business improvement order by Japan’s Financial Services Agency.

Last month, Tokyo market operators said there was no indication of a cyberattack, and the problem had been traced to a memory breakdown that failed to properly trigger a switch to a backup system.

They said the faulty hardware had been replaced, and that personnel would be deployed to monitor the system to avoid a repeat.

JPX is the globe’s 3rd largest exchange by market capitalization, at an estimated $5.1 trillion, including listings on exchanges outside Tokyo.

It sits behind only the New York Stock Exchange and Nasdaq, according to the World Federation of Exchanges. – Rappler.com
