Tokyo Stock Exchange Has Yet Another Hiccup

The Tokyo Stock Exchange (TSE) was forced to suspended trade in futures and options contracts at 0921 Tokyo time Tuesday and was not able to resume trading until halfway through the afternoon session, beginning at 1345.

According to a report in the International Herald Tribune, "The TSE has been upgrading its systems and working to regain the trust of investors after a series of computer mishaps in the past few years, including three months of limited trading hours after a stock sell-off in 2006 swamped its systems."

I guess there is still more upgrade work to be done.

The TSE expressed its "deepest regret for the inconvenience caused."
