The Reserve Bank of India (RBI) has reportedly found a string of anomalies and violations on several counts by banks.

The central bank, which had launched a probe in wake of Cobrapost's sting operations showing officials of nearly 33 public and private sector banks facilitating money laundering, found that non-compliance to Know-Your-Customer (KYC) norms, usage of dummy PAN cards, and unauthorized gold sales are widespread among banks.

As per sources, Axis Bank allowed customers to split cash deposits to avoid reporting transactions under cash transaction reports. The bank didn't even record many large cash transactions. In one case, this bank sold gold worth more than Rs 5 lakh without demanding PAN from the buyer.

ICICI Bank allowed some customers to make cash transactions worth over Rs 10 lakhs in NRO accounts without asking them to reveal their identity. This private sector bank also allowed depositors to deposit cash above Rupees fifty thousand without PAN card.

HDFC Bank misled the central bank with false compliance on yearly financial inspection. This private sector lender has also been found in breach of norms set for compensation for MD and CEO.

The central bank also found that insurance subsidiaries of the respective banks were sponsoring irregular foreign trips of their respective banks' staff.
