In a Credit Outlook article, Moody's said that it signals improved access to the equity capital markets and will reduce PSBs' dependence on fund infusion from the government.
"The inability of most PSBs to access the equity markets has been a key capital constraint. The share prices of most PSBs that we rate improved substantially after the Indian governments October announcement of the recapitalisation package for the countrys 21 PSBs," it said.
"The PSBs' capital raises are credit positive because they will help improve the banks loss-absorbing buffers ahead of the gradual phase-in of Basel III norms in the country," it said.
On a pro forma basis, it said, the capital raise will add about 100 basis points to PNBs Common Equity Tier 1 (CET1) ratio, which was 8.1 per cent as of September 2017.
UBI and Syndicate each will add 60-70 basis points to their CET1 ratios, which were 7 per cent and 7.2 per cent, respectively, as of September 2017, it added.
