This was also in line with global trends. As a research article by economists at the Reserve Bank of India, published in its latest monthly bulletin, highlighted, there has been a shift towards defined-contribution pension plans from defined-benefit arrangements in various parts of the world. Several countries have also taken steps such as reducing pension benefits, increasing the retirement age, and raising contribution rates to reduce the burden on the exchequer. This is, in fact, necessary to maintain fiscal balance and protect essential spending on growth and development. In the Indian context, the states’ expenditure on pension has increased from 0.6 per cent of gross domestic product (GDP) in the 1990s to 1.7 per cent of GDP in 2022-23.
Since defined pension is paid from the current revenue of the government, it is worth noting that the pace of increase in pension liabilities has been higher than revenue growth, and that is simply unsustainable. In some states such as Bihar, Kerala, Uttar Pradesh, Punjab, and West Bengal, the pension outgo is in excess of 25 per cent of their revenue receipts. The immediate fiscal reason for going back to the OPS could be that the state will not have to contribute to the NPS corpus. But this is a short-sighted move because states are giving up the long-term gains of moving to the NPS. The yearly contribution of states to the retirement corpus under the NPS, according to the above-mentioned study, is expected to increase from 0.1 per cent of GDP to 0.2 per cent by 2039 and will start declining after that. This will drop to zero if states go back to the OPS. However, the outgo in the future would increase because all employees will be eligible for pension under the OPS.
The move to the OPS also seems politically motivated because, generally, employees prefer defined benefits. The risk thus is that more state governments may opt for it under political and electoral pressure. On the fiscal side, the study concludes that the cost of reversal will be enormous and the eventual pension outgo would increase by about 4.5 times than it would under the NPS. The actual amount, to be sure, is difficult to calculate because of potential changes in salary and pension, and other factors. Nonetheless, it is safe to argue that costs will increase over time and affect the discretionary spending of states. The states should thus resist opting for short-term fiscal and political gains.
