A world-renowned bank, Citi, mistakenly transferred 6 billion dollars to a customer’s account. An employee at the US-based bank Citigroup accidentally transferred 6 billion dollars to the customer’s account. The bank employee copied the account number and pasted it into the amount field to be sent by mistake. The error was detected the following business day. The bank announced that the input error was identified and corrected, with no impact on the bank or the customer. Financial Times reported last week that Citigroup mistakenly deposited 81 trillion dollars instead of 280 trillion dollars into a customer’s account and it took hours to reverse the transaction. Bloomberg also announced that both errors occurred in April. Following the first reported incident, it was noted that Citi implemented measures to eliminate manual processes in money transfers.
