What Does Karnataka Bank’s ‘Fat Finger Error’ Mean?
What is this massive Rs. 1 lakh crore fat finger error at Karnataka Bank.
Although the money was wrongly credited to a dormant account and the transaction was reversed within three hours, the bank stressed that there was no financial hit or customer impact.
Since there was no immediate loss, why did RBI view the incident so seriously and categorize it as a “Serious Compliance Failure”?
This Rs. 1 lakh crore fat finger error occurred on 9-August-23.
It happened when a bank staff member mistakenly keyed in extra zeros during routine data entry. Fortunately, this astronomical entry was made into a dormant account, meaning no actual funds were moved.
The bank’s internal systems detected the anomaly within three hours (by 8:09 PM), and the error was completely reversed. It was corrected that same night. This ensured that there was no financial loss or adverse customer impact.
However, RBI focused heavily on the six months of silence that followed the event. The incident, though corrected immediately, was not officially disclosed to the bank’s Board until March 28, 2024.
Even more critically, the RBI only learned about this system’s glitch and failure during its supervisory inspection in October 2024.
This massive delay in reporting transformed a clerical mistake into a systemic failure. RBI categorized it as a “Serious Compliance Failure.”
