Software Glitch Halts Tokyo Stock Exchange
A software error related to a system upgrade halted stock and bond trading on the Tokyo Stock Exchange. Problems came to light before the market's opening at 9 a.m. local time and delayed the start of trading until 1:30 p.m. The glitch was the most serious to hit the exchange since 1999, when floor trading was scrapped so that an all-electronic trading system could be installed.
