Policy toward inflation in India has a somewhat chequered history (e.g. Mohan and Ray 2018, Das 2020, Hutchison et al 2013.) Inflation in India has averaged 8% or more since the 1980s, except in the early 2000s when it averaged 4% and more recently when inflation fell with the move to inflation targeting. Levels have exceeded average global inflation for the most part (Figure 1), while fluctuations have broadly tracked those in other low- and middle-income countries, aside from 2009-2015. Basu et al. (2014) attribute India’s relatively high inflation in this period to budget deficits and monetary policy accommodation in years that coincided with national elections.

The Reserve Bank of India (RBI) has followed a variety of policy strategies over the years. Following a long period of fiscal dominance during which the central bank was expected to monetise budget deficits, the fiscal framework was reformed and strengthened in the early years of the current century, allowing the RBI to exert more independence and bring inflation down to levels characteristic of other low- and middle-income countries. This transition culminated in the inflation-targeting agreement of February 2015 and an amended RBI Act in May 2016, which gave the central bank a statutory inflation target. At this point the RBI adopted a full inflation-targeting (IT) framework, emulating international best practice.
These changes are recent; the amended RBI Act recently celebrated its fourth anniversary. Consequently, their consequences have been the subject of little systematic analysis. Moreover, their efficacy is now being subjected to ‘the mother of all stress tests’ in the form of the Covid-19 pandemic.
Four years of experience is just enough on which to base a preliminary analysis, and the challenge of the pandemic makes it even more important to extract lessons from that experience. This is what we seek to do in a recent paper (Eichengreen et al. 2020).
Some of our findings may be surprising. Contrary to conventional wisdom that the RBI should focus on core inflation and ‘look through’ volatile and transient food-price inflation, we find that food-price inflation can de-anchor expectations and spill over into core inflation; by implication, monetary policy should respond. Food prices account for a much larger share of consumption baskets in India than in many other countries. It follows that they cannot be benignly neglected by the RBI as they are by many, if not most, advanced-country central banks.
We show that the RBI is best characterised as a flexible inflation-targetter: contrary to criticism, it does not neglect changes in the output gap when setting policy. We do not find that the RBI became more hawkish following the transition to IT; to the contrary, adjusting for inflation and the output gap, policy rates became lower, not higher.
Figure 2 Expectations before and after inflation targeting
Importantly, we find evidence that inflation has become better anchored. Both the inflation forecasts of financial professionals and the responses to inflation forecasts of households declined with the shift to IT, although household expectations of inflation continue to consistently exceed actual outcomes (Figure 2).
Moreover, increases in actual inflation now do less to excite inflation expectations, indicative of improved anti-inflation credibility. This is true for the expectations of both households and professional forecasters, although the change is largest and most significant for the financial professionals.
Further consistent with this conclusion of better anchoring, a number of inflation-related outcomes – the level and volatility of inflation, the stability of inflation expectations, the behaviour of ancillary variables such as the exchange rate and equity markets – are more stable than before (Figure 3).

Note: Inflation volatility is computed as 15-month rolling standard deviation of monthly inflation series which is then averaged at quarterly frequency.
Covid and credibility
Finally, we ask whether the RBI, having gained credibility with the shift to IT, is in a position to take extraordinary steps in response to Covid-19. We argue that this is the case, and that rules like those governing modern IT regimes come with implicit escape clauses allowing central banks credibly committed to those regimes to deviate, under exceptional circumstances, without untoward consequences. Specifically, we show that the better anchoring of inflation expectations has enhanced the scope for the RBI to respond to an exceptional shock like the Covid pandemic – a shock that is (i) independently verifiable and (ii) not of the authorities’ own making – despite the fact that inflation was already running at the top of the target range and that Covid, as a negative supply shock, might be expected to raise inflation. We provide evidence that inflation targeting central banks were able to respond more forcefully to the Covid-19 crisis, consistent with the idea that inflation expectations were better anchored, giving them more policy room for manoeuvre.
Inflation targeting in India is barely four years old, a fact that has hindered earlier efforts at performance evaluation. Here we take advantage of the (limited) accumulation of data to analyse what if anything changed with the advent of IT. We show that the RBI is best characterized as a flexible inflation-targetter: contrary to some assertions and criticisms, it does not neglect changes in the output gap when setting policy rates. We do not find that the RBI became more hawkish following the transition to IT; to the contrary, adjusting for inflation and the output gap, policy rates became lower, not higher. We find some evidence that inflation has become better anchored: increases in actual inflation do less to excite inflation expectations, indicative of improved anti-inflation credibility. This is consistent with the fact that a number of other inflation-related outcomes are more stable post-IT than before.
Finally, we ask whether the shift to IT has enhanced the credibility of monetary policy such that the RBI is in a position to take extraordinary action in response to the Covid-19 crisis. We argue that the rules and understandings governing IT regimes come with escape clauses allowing central banks to disregard their inflation targets, under specific circumstances satisfied by the Covid-19 pandemic. Cross-country comparisons confirm that inflation targeting, in conjunction with related institutional arrangements, had benefits in terms of additional policy room for manoeuvre in the crisis.
