System glitch at Deutsche Bank unit hits Japan bourses
Deutsche Securities said Wednesday it mistakenly placed sell orders worth 16.7 trillion yen (182 billion dollars) at Japan's second largest bourse due to a software glitch.
The subsidiary of Germany's Deutsche Bank placed the orders for 1.24 million Nikkei 225 futures contracts and 4.82 million Nikkei 225 mini-futures contracts in the first minutes of trade at Osaka Securities Exchange Tuesday.
The orders were more than ten times the Osaka exchange's average daily volume and one of the largest trading errors in Japan, prompting regulators to begin an investigation.
After the orders were placed, the Tokyo Stock Exchange's Nikkei-225 futures index lost 110 points or one percent, reports said.
The erroneous trades were executed by the group's proprietary trading unit, which trades on the bank's account and not for clients. Activity on proprietary trading has been suspended, the bank said on its website.
"There was a software glitch in our automated trading system, and the consequence of the error was that a number of trades were repeatedly sent to the exchange," Deutsche Bank spokesman Aston Bridgman said Wednesday.
"The error was recognised and we immediately placed cancel orders on 99.7 percent of the trade. There is an issue somewhere in the software that needs to be identified," he added.
The remaining orders that were executed amounted to 55 billion yen, he said. The bank's proprietary trading unit has its own trading platform and software, although the spokesman declined to provide details.
Tokyo stock markets went into turmoil in December 2005 after a Mizuho Financial Securities trader punched in an order to sell 610,000 shares in a telecom firm at one yen each instead of one share at 610,000 yen.
The chaos prompted the resignation of the head of the Tokyo Stock Exchange to take responsibility. A court last year ordered the TSE to pay compensation of more than 120 million dollars over its failure to stop the blunder.
