The bank recovered the amount from the client the next day and the incident was reported to the US Federal Reserve, the European Central Bank, and the UK Financial Conduct Authority, the newspaper reported.
The trade was processed by a junior member of the bank’s London-based forex sales team in June while his boss was on a holiday, the FT reported, citing two people familiar with the matter.
The error occurred when the trader processed a gross figure instead of a net value that resulted in the trade having “too many zeroes”, the newspaper said.
Such mistakes are referred to as ‘fat finger’ trades, when a keyboard error in the financial markets leads to traders placing an order to buy or sell of much larger size than intended.
Such mistakes are common but of this size are rare, the FT reported.
Deutsche Bank was not immediately available for comment.
