A 28 billion-euro ($35 billion) payments error at Deutsche Bank AG in March wasn’t the first such blunder to befall the lender.
In March 2014, the German bank mistakenly sent 21 billion euros to Macquarie Group Ltd. as collateral for an over-the-counter derivatives trade, according to a person familiar with the matter who declined to be identified, according to bloomberg.
That incident led directly to the introduction of fail-safes.
