Typing error costs Japanese broker €190m

Japan’s government rebuked the Tokyo Stock Exchange and one of the country’s biggest brokerage firms today after a typing error caused Mizuho Securities to lose at least 27 billion yen (€190m) on a stock trade.

The glitch upset the Japanese market, while jitters over the reliability of the exchange’s trading system contributing to a 1.95% drop in the benchmark Nikkei 225 index yesterday.
