In written reply, Finance Minister Arun Jaitley said that minor and major penalties have been imposed against erring officials. These include, dismissal, compulsory retirement and demotion.
"As per the inputs received from nationalised banks, in FY 2017-18, 6,049 officers have been held responsible on account of staff delinquency in NPA accounts...," Jaitley said.
Depending upon the gravity of lapses, the minister said "minor penalty/ major penalty have been imposed against erring officials" and in all the cases, depending upon the amount involved, CBI and police complaints have been lodged.
The 19 nationalised banks, including PNB and Canara Bank, reported a net loss of Rs 213.88 billion in the first half of the fiscal. This compares with a combined loss Rs 68.61 billion in the similar period of 2017-18.
Meanwhile, Minister of State for Finance Shiv Pratap Shukla said that no loan account of state-owned banks with outstanding of over Rs 250 million has been "declared as evergreen" since June 2014.
In another written reply to the lower House, Shukla said as a result of transparent recognition of bad loans, the non-performing asset (NPA) amount of all commercial banks rose from Rs 5.66 trillion at end-March 2016 to Rs 9.62 trillion at end of March 2018.
Since then the amount has declined to Rs 9.43 trillion.
He further said the public sector banks have reported a "record recovery" of Rs 607.13 billion in the first half of the current financial year.
This, he said, was double the amount recovered by them during corresponding period of the last financial year.
