Besides, if the government goes for another consolidation like Bank of Baroda, the three-way merger would also require additional capital, the sources said.
It is to be noted that the government infused Rs 5,042 crore in BoB to enhance its capital base to meet additional expense due to amalgamation of Dena Bank and Vijaya Bank.
In all the the government made record capital infusion of Rs 1,06,000 crore in the public sector banks last fiscal. It was enhanced from earlier provision of Rs 65,000 crore in December 2018.
As a result of capital infusion, five banks - Bank of India, Oriental Bank of Commerce, Bank of Maharashtra, Allahabad Bank and Corporation Bank - came out of PCA. Following merger of Dena Bank with BoB, it also came out of weak bank category. Out of 11, only five are left under weak bank category of the Reserve Bank of India.
As far as their own resource mobilisation are concerned, sources said, they are unable to tap capital market because of their low share prices.
They are banking on sale of non-core assets which are not enough, the sources said, adding that PSBs would require capital infusion from the government this fiscal as well.
How much will come would depend on the government fiscal math that the Budget division of the Finance Ministry will take a final call near Budget preparation, the sources noted.
Initial estimate indicates capital requirement of Rs 20,000-30,000 crore, provided banks are also able to raise funds on their own from the market both through asset and share sale, they added.
Many banks, including State Bank of India and Bank of Baroda (BoB), have already got the board approval for capital raising as and when required.
For example, BoB plans to raise Rs 11,900 crore during the current fiscal through share sale, including Employee Share Purchase Scheme to shore up capital for meeting business expansion requirement.
The bank expects to garner Rs 1,500 crore from Bank of Baroda Employee Share Purchase Scheme (BoB-ESPS). ESPS will be within overall limit of capital plan 2019-20 of Rs 11,900 crore.
