New Delhi:  The finance ministry on Tuesday set a 15-day deadline for state banks to take pre-emptive action against operational and technical risks, following a USD 2 billion fraud at Punjab National Bank (PNB), India's second-biggest state lender.

Rajeev Kumar, secretary in the department of financial services, said in a tweet that state-run banks have 15 days to "take pre-emptive action and identify gaps/weaknesses" to tackle rising operational and technical risks.

Besides fixing "clear accountability" of senior officials, the banks must also learn from best practices and pinpoint strategies including technical solutions, Kumar added.
