"Neither the payments banks nor small finance banks seem to have as yet devised a business model that can be said as viable," said Bhattacharya, whose bank has tied up with Reliance Industries for a payments bank venture.
Addressing a banking seminar organised by industry lobby IMC here, she added, "...A mobile banking customer, who is also a customer for payment services, will be less free to migrate to a competition for mobile services. Hence, it is hard to see payment banks taking away customers or income from commercial banks in a big way. Similar arguments hold for small finance banks."
This is the third time the SBI chief has cast doubts over the payments banks model. At one public event, she went to the extent of saying that with deep-pocket corporates entering payments banking, it would be a "dog eat dog" scenario in the sector.
Bhattacharya's comments come within a fortnight of RBI saying it will allow differentiated lenders like custodian and wholesale banks. The RBI has already issued in-principle licences to 10 payments banks and 11 small finance banks.
Noting that technology will play a bigger role in banking, she said the potential of technology, mainly mobile phones, to deliver banking services was recognised way back in 2010.
She said mobiles offer the cheapest mode of banking.
"A mobile banking transaction costs about 2 per cent of the bank branching cost, 10 per cent of ATM-based transaction and 50 per cent of the Internet banking cost," she said.
Admitting rising competition, Bhattacharya said the share
of top five banks in the total market has fallen from 46 per cent in 1998 to 39.5 per cent now. She added that the recent RBI decisions on new players will only increase competition.
Ruing the decline of cooperative, local area and regional rural banks, Bhattacharya said "Very little attention is being given to these banks."
"The feeling that I get is that people seem to have given up on these smaller banks. I believe that this existing sector needs reforms very badly as they are not actually controlled by the Reserve Bank," she said.
She said as the industry prepares for more competition from the new players, "we should also look at what the government machinery and the regulator are doing to make sure these existing banks are made ready for competition and some amount of handholding is provided to these institutions."
Admitting that banks are going through a period of stress, Bhattacharya said, "It is as if the global financial crisis is affecting our economy with a lag. However, it would be unwise to draw conclusions or prescriptions about our banking by reading the performance indicators over the past three years of stress."
