No Proof Required: RBI, enough of elevator economics

The inflation forecast is the most important aspect of the most crucial economic decision that the RBI makes — it needs to be more in tune with reality.

The Indian economy has likely gone through a mega structural-break experience via demonetisation. A major institution in India, the RBI, was, by definition, right in the thick of this entire experiment. Unfortunately, too much ink has been spilled on the decision of whether it was appropriate for the economic body to agree to the demonetisation option. My own personal view is that while the RBI was the technical authority to agree to the demonetisation decision, it wasn’t under its mandate, or authority, to not agree to the political decision.
What is clear is that the RBI faltered, and faltered badly, in the implementation of the decision. Its reputation has taken a beating, and it is unfortunate that all the blame for the faulty implementation has been foisted onto the new RBI governor Urjit Patel. This is worse than baptism by fire, but it is very much a part of the prestigious and powerful job as the head of one of the major institutions of India.

In September 2016, a new institution was created within the RBI — the Monetary Policy Committee (MPC), a six-member committee to decide on monetary policy. It is the functioning of this new eight month-old institution that I want to discuss. The MPC members are presumed to be the best and brightest in India on the subject of monetary policy. What does the performance to date reveal?

Very early on, an important part of a child’s education is the learning of the three R’s — reading, (w)riting and (a)rithmetic. Analogously, a critical part of a central banker’s education is to follow the 3C’s — Clarity in thought, (logical) Consistency and effective Communication. If the three C’s are kept in mind, the central banker (or MPC member) achieves the ultimate goal — Credibility.

Communication is the easiest of the three C’s, yet an area where the MPC has performed badly. Very early on, reporters of major news agencies (BBC, The Economist, Firstpost) were shut out, Trump-like, from press conferences. Was this done because they would not be docile and feed lollipop questions to the RBI brass at the policy press conferences? The new RBI has also stopped publishing transcripts of post-policy discussions with investors. Why? By any definition, this qualifies as very poor communication — and with precious little

But it gets worse. MPC members are prohibited (again, the favourite Indian policymaker policy — when in doubt, ban) from talking to experts, journalists, etc., about their thinking, and/or their justification, for the policy decisions they have made and published in the minutes of the MPC meeting. It is perfectly understandable (indeed required) that leading up to the policy decision, there be a quiet period. But post-the decision?

The reason all of this is very relevant is because the MPC makes some important decisions affecting the lives of all Indians — their judgement, and particularly their judgement on past and future inflation, affects their decision on interest rates, and this decision affects all aspects of our economy. Indeed, for most countries, developing and developed, the interest rate decision is the most important economic decision made by any part of the government, including the ministry of finance. And we are being told that this decision is now being made by the SSS (super secret society)?

What compounds the error of secrecy is that it appears that the new RBI decisions are not supported by data on inflation. The inflation forecast is the most important aspect of the most crucial economic decision. How has the new RBI performed on this parameter? Extraordinarily poorly.


In December 2016, the MPC made the bold forecast that headline inflation in India would average 5 per cent in January-March 2017, and there was an upside bias! This forecast was post-demonetisation and the minutes of the meeting do indicate that the RBI was well aware of the possibility that headline inflation would fall. Yet, they persisted with their forecast, and one that the docile bureaucratic babu-pink press did not question much.

The actual inflation during January-March turned out to be 3.6 per cent, a full 1.4 percentage points below the three-month forward forecast. This (absolute) error is double the average error over the previous three years (2014 to 2016). In percentage error terms (in this instance, the error is 39 per cent), this error is larger than at any time in RBI history. In the three prior years (2014-2016), the error averaged 0.7 percentage points, or an average 12 per cent error.

In other words, the MPC error in 2017 (the easiest forecast because of demonetisation) was more than three times the average error over the last three years.


Some of us had explicitly said that actual inflation January-March 2017 would be nowhere close to the judgement of the expert MPC. Why are these errors so large? Perusing through the MPC documents (and similar documents in other countries), it does appear that errors are common because our own RBI indulges in what can only be called elevator economics — the entire “analysis” is composed of statements that this went up, and that went down. Period. There is no attempt at analysis or the explanation of why.

What is discouragingly amusing is that the MPC does not even get its analysis of the past right! In an earlier article (‘Jaywalking at the RBI’, IE, February 25), I had mentioned the faulty data used by the RBI on core inflation —a critical variable for policy. What the nation should know is that the 51-page semi-annual Monetary Policy Report does not mention the word “core” with reference to Indian inflation even once! But, true to its commitment to elevator economics, the MPR discusses the pattern of every conceivable measure of inflation (food, vegetables, fruit, pulses, perishables, excluding food and fuel, etc.) — except core.

The reason it does not mention core (defined as CPI minus food minus fuel and minus petrol) is because the conclusion goes against the MPC mantra that “inflation excluding food and fuel” has been sticky at 5 per cent. But nowhere does the RBI mention the fact that this stickiness is only there if petrol prices (contained not in “Fuel” in the Indian CPI but in “Transport and Communications”) are not excluded from the calculation of core.

True core inflation rate has been declining, that is, it has not been stable. Indeed, there has been a systematic decline in the true core rate to now the lowest level (4.3 per cent) in the last nine years (since June 2008). In October 2016, the month before demonetisation, true core inflation in India was 4.9 per cent; a year ago (March 2016), true core inflation was 5.1 per cent.

Many analysts have called the RBI’s bluff on “core inflation”. This may be one reason why the MPC has now turned to a discussion of the following (changing of goalposts in the game of elevator economics): In the latest MPC minutes, Governor Patel concludes (along with MPC members Patra, Ghate and Dua) that “CPI inflation excluding food and fuel remained sticky, especially services”.


Let us see how the RBI performs with respect to documentation of past inflation data — a simpler exercise than a forecast. Very poorly, but you be the judge. The table documents the weight and CPI inflation, for the six most important categories of service inflation. Data are presented for three months: March 2017, March 2016, and the month prior to demonetisation, October 2016. The six categories are combined, in a weighted fashion, to yield a composite service inflation with a weight of 34.3 per cent in the total CPI.

Far from being sticky, each component of service inflation shows a large year-on-year (y-o-y) decline, ranging between 130 basis points (health) and 30 basis points (housing). The weighted average decline is 80 basis points. Further, the level of service inflation in March 2017 (4.1 per cent) is within kissing distance of the 4 per cent target of headline inflation of the MPC.


But there is some really good news about the MPC — dissent has finally reached its shores! Ravindra Dholakia openly disagrees with the other MPC members on the trend in future inflation. Dissent is very difficult in the Indian bureaucracy — the fact that it has happened means that MPC future policy decisions will be considerably more balanced, and informed.
