A fat finger error committed at Karnataka Bank, which dates to August 2023, is now drawing much attention. Internally, the leadership team at Karnataka Bank is busy strengthening its processes as officials at the Reserve Bank of India question the bank over the lapse in controls and risk management. Highly placed sources aware of the development say the fat finger error is among the core issues that has caught the regulator’s attention in the current year’s ongoing annual supervision.

“Even though the incident occurred about two years ago, given the quantum involved and how it has been handled so far, it is drawing a lot of interest,” said a senior executive associated with the bank who did not want to be identified.

According to documents accessed by Moneycontrol, the extent of error committed pertains to a single transaction amounting to Rs 1,00,000 crore.

The entry was reversed at 20:09 hours on the same day, roughly within three hours after the incident occurred.
