They could see negative pressure on their credit profile if the government does not revise upwards its capital infusion plans, Moody's Investors Service VP Financial Institutions Group Alka Anbarasu said.
"Given the weak solvency position of many PSBs, we expect the remedial measures will require substantial external capital. With little chance of the banks accessing the capital markets in the near term, we expect much of the capital support will be required from the Indian government," she told PTI.
They are undertaking asset quality review following the Reserve Bank's diktat and this has led to rise in bad loans and provisioning. RBI has also asked PSBs to clean up their balance sheets by March 2017.
"From a timing perspective, the front-ending of problem loans recognition and provisioning requirement has up fronted the capital requirements of the Indian public banks. Hence, unless the government revises upwards its capital infusion plan, there will be negative pressure on the credit profiles of these banks," Anbarasu said.
The capital infusion roadmap indicates that the overall capital requirements of the banks over the four-year period would total Rs 1.80 lakh crore. The remaining Rs 1.10 lakh crore is to be raised by PSBs from the markets.
Moody's currently rates 11 PSBs, including State Bank of India, Punjab National Bank, Bank of Baroda, Bank of India, Canara Bank and IDBI.
