Previously, we shared how Citigroup accidentally credited a staggering USD81 trillion into a customer’s account when it was only meant to credit USD280.
The incident happened in April 2024 but was only recently made public, and now, another glaring error made by the financial group during the same month was unearthed, this time involving USD6 billion or approximately RM26.81 billion.
A Citigroup staff’s copy-paste error caused its wealth division to transfer USD6 billion to a customer accidentally

For illustration purposes
In a report by Bloomberg, it was revealed that the company mistakenly shifted USD6 billion to a customer’s account due to an error by the staff at its wealth division that was handling the transfer.
The staff mistakenly copied and pasted the account number into the field for the dollar figure, resulting in an amount being transferred that was more than a thousand times larger than what it was supposed to be.

Thankfully, the error was detected the next working day and reported to regulators. In a statement, the financial group asserted that it “promptly identified and corrected” the “inputting error” and assured that it had no impact on the bank or its client.
Citigroup further stressed that it had since implemented enhanced preventative measures, which are consistent with its continuing efforts to eliminate manual processes and automate controls.
The much larger USD81 trillion error lessened the pressure on the managers involved in the USD6 billion mistake

Rather expectedly, the error caused hullabaloo within Citigroup’s offices, with the Bloomberg report quoting an insider who revealed that the copy-paste error provoked audible frustration from Andy Sieg, a Citigroup executive who had arrived just months earlier to run the wealth division unit.
Furthermore, Citigroup executives were in the midst of discussions with higher-ups and regulators over how to address the error when they were informed of the much larger USD81 trillion error, which gave some of the managers in the wealth division some bittersweet relief.
The firm has since introduced a companywide tool to help vet large, anomalous payments and transfers so that such errors won’t happen again.
