The Long-Term Issuer Default Ratings (IDR) on State Bank of India, Bank of Baroda, Bank of Baroda (New Zealand), Punjab National Bank, Canara Bank, IDBI Bank, ICICI Bank and Axis Bank have been affirmed at 'BBB-'.
In case of Indian Bank, the agency has affirmed the IDR, which opine on an entity's relative vulnerability to default on financial obligations, at 'BB+'.
"The outlook on the IDRs is stable," Fitch Ratings said in a statement.
"The downgrade also reflects Fitch's expectation that capital buffers are unlikely to improve significantly even though the state is likely to inject capital into the bank in the financial year ending 30 March 2016 (FY16), with the bank's large stressed assets stock potentially taking longer to resolve than that of its peers," it said.
In July, the agency had cut its India real GDP growth forecasts to 7.8 per cent for FY16 from 8 per cent, and to 8.1 per cent for FY17 from 8.3 per cent.
Fitch further said that the outlook for Indian bank credit profiles in FY16 is more positive following the difficult year in FY15, when system-wide loans increased by 9.7 per cent, the slowest pace in a decade.
"There are, however, challenges from stressed sectors such as infrastructure and steel, high corporate leverage, and continued pressure on asset quality and capital," it added.
On government's capital infusion of Rs 70,000 crore in public sector banks, Fitch said it should provide some support for the state-owned banks' ailing balance sheets, but may not be sufficient, depending on banks' credit growth expectations and persistent low equity valuations.
The rating agency also said that government's seven-part plan to reform PSU banks could be a significant step towards increased transparency, better governance and greater accountability for the sector, provided government interference is minimised.
