The gross NPAs of banking sector are estimated at over 5 per cent of total loans, while overall stressed assets (including declared and potential bad loans) are at about 11 percent.
This is nearly 1.5-times of their total market value, which currently stands at Rs 2,62,955 crore.
As per RBI, an asset becomes non-performing when it ceases to generate income for the bank. The banks need to declare a loan as NPA which remains overdue for more than 90 days.
The gross NPA of 16 listed private sector lenders stood at Rs 46,271 crore as on December 30, 2015. This compares with their total market value of over Rs 7 lakh crore.
The banks have taken a big beating on their valuations in recent weeks on investor concerns over bad loans.
Raising concerns about the ballooning bad loans, eminent banker and HDFC Ltd Chairman Deepak Parekh said last week that the health of banking sector is one of the key issues impacting the Indian economy.
The quarter ended December 31, 2015 has been even more brutal for banks, with at least ten lenders posting gross NPAs in excess of 8 per cent and 22 others of more than 5 per cent.
“While I absolutely do not wish to second guess the regulators and I do not at all doubt their competence in assessment of the situation, I only wish to caution that too much of anesthesia can also result in a patient becoming comatose!” Parekh cautioned.
