The government should come up with a 10-year road map for privatisation of all public sector banks (PSBs) as it would provide much needed predictability to stakeholders, former RBI Governor D Subbarao said.

The big bang approach to privatisation of state-owned banks is not desirable but at the same time the issue should not be put on the back burner, Subbarao added.

"Ideally, we should have a road map, maybe over a 10-year timeframe, to privatise all PSBs. That will give much needed predictability to all stakeholders," he told PTI.

Meanwhile, the government should also be thinking about corporatisation of PSBs so that they come within the umbrella of uniform RBI regulation.

In the Union Budget for 2021-22, the government announced its intent to take up the privatisation of two PSBs in the year and approved a policy of strategic disinvestment of public sector enterprises.

The government think-tank NITI Aayog has already suggested two banks and one insurance company to the Core Group of Secretaries on Disinvestment for privatisation.

According to Subbarao, the impact on the Indian economy of privatisation of PSBs will be in two ways.

"The overall efficiency of the banking system will improve as public sector banks, freed from the obligation of driving social objectives, will pursue profit maximisation like their private counterparts," he told PTI, adding that the pursuit of social objectives like financial inclusion and priority sector lending might, to some extent, be compromised.

Even so, Subbarao said he believes the net cost benefit calculus of privatisation will be positive.

In 2020, the government merged 10 nationalised banks into four large lenders, thereby bringing down the number of PSBs to 12.

The former RBI governor observed that at India's current stage of development, the country should be using other instruments to pursue social objectives rather than continuing to place the burden on bank depositors and borrowers, PTI reported.

A research paper published in the August 2022 issue of RBI Bulletin had said "the gradual approach to privatisation adopted by the government can ensure that a void is not created in fulfilling the social objective of financial inclusion".
