Government's decision to inject Rs 22,900 crore (USD 3.4 billion) into 13 public sector banks, including PNB, SBI and Bank of India, is supportive of the credit profiles of these lenders, it added.
"That said, this step, on its own, is unlikely to address the pressures on the system driven by economic growth in light of the significant asset quality pressures and weak profitability prospects of these banks," the agency said.
In a statement, Fitch said that it estimates Indian banks will need USD 90 billion in total additional capital, "most of which will be accounted for by the public banks", to meet Basel III requirements by 2019.
Banks other than the 13 in yesterday's announcement will need to source additional capital, Fitch said.

"Fitch believes pressures on public bank credit profiles will remain, and more capital than the Rs 70,000 crore (USD 10.4 billion) earmarked through to FYE19 will be needed from the government to restore market confidence and position the sector for long-term growth," the statement said.
Losses at public-sector banks in the second half of the fiscal year ending March 2016 were double the government's capital injection in FY16, and eroded the equivalent of nearly 15 per cent of end-FY15 capital, Fitch said.
Earlier this month, Fitch revised the sector outlook for Indian banks to negative from stable in part due to the rapid accumulation of stressed assets that have outpaced capital replenishment.
The market currently values almost all of the listed public banks at well below book value.
Domestic rating agency Icra said the front-loading of the
capital infusion for 2016-17 is positive and will immediately support the state-run banks' capitalisation levels.
Icra expects public lenders' tier 1 capital requirements to be in the range of Rs 40,000-50,000 crore for the current financial year, which is higher than the government's Rs 22,915-crore equity infusion.
"And these lenders internal capital generation is likely to remain muted on the back of significant pressure on their asset quality," Icra said.
