The Tokyo Stock Exchange halted trading in all listed stocks for a full day Thursday due to the biggest technical glitch it has experienced since it introduced a computer system in 1999.
The unexpected shutdown came about due to a hardware glitch inside the trading system, Japan Exchange Group (JPX) Chief Information Officer Ryusuke Yokoyama told reporters, adding that it was not due to cyberattacks, as the malfunction occurred in areas that are not connected to the internet.
The exchange is preparing to resume trading Friday by restarting the overall system, he said.
