Let's start with the payments banks. According to RBI's guidelines, these banks can only accept deposits, provide remittance services, issue ATM/debit cards (not credit cards), act as a business correspondent of another universal bank, distribute third-party investment products (another company's mutual fund, insurance or pension fund products), among other things. But there's one big difference: payments banks cannot lend. On top of which, they have to invest 75 per cent of their deposits in government securities or treasury bills with a maximum maturity of one year, and the balance 25 per cent in fixed deposits or current account of another scheduled commercial bank.
This brings us to the second point: The pathway to a respectable rate of return for payments banks seems ridden with multiple potholes. As per the guidelines, payments banks have four key areas of business opportunity, all of which yield fee-based incomes: fee from remittances, fee from transaction services (such as debit cards), fees from sale of third party investment products, fees for providing business correspondent services.
But given the capital cost, the network roll-out expenses and the cost of managing operational risks, this revenue source might not be enough to provide adequate returns. Or, the volumes that will be required to generate adequate returns might be difficult to achieve. Plus, given the demographic profile of a payments bank's core constituency, ticket sizes are likely to be small and perhaps misaligned with acquisition costs. This is despite use of technology solutions to lower costs.
On top of this, the payments bank will have some genuine dilemmas. One, how does it price deposits? If it's lower than universal banks, it could raise issues of discrimination. Also, if it has to make a spread from investing in gilts, then deposit rates have to be lower than the sovereign yield rates. Will anybody bite at these rates? It will, therefore, have to rely on high-yield fees, such as those paid on sale of insurance or pension products. Some kind of regulatory framework might be necessary here, given the scope for mis-selling.
