The most important measure of inflation in India is the year-on-year change of the CPI-IW index. This time series, for 120 months, is shown above. From 2006 onwards, India slipped into a new phase of macroeconomic instability, where inflation has strayed far outside the informal target zone of inflation at four-to-five per cent.
Has inflation subsided?
In recent months, there has been a surge of optimism that the inflation crisis is coming to an end. However, a careful look at the seasonally adjusted data reveals that there is cause for concern.
| Month | P-o-p SA | Y-o-y |
| Sep 2011 | 17.49 | 10.06 |
| Oct 2011 | 2.01 | 9.39 |
| Nov 2011 | 3.11 | 9.34 |
| Dec 2011 | -2.14 | 6.49 |
| Jan 2012 | 8.22 | 5.32 |
| Feb 2012 | 12.01 | 7.57 |
In September 2011, point-on-point seasonally adjusted (annualised) inflation was at 17.49 per cent. The year-on-year inflation was running at 10.06%.
We then had three good months: October, November and December, where the point-on-point seasonally adjusted (annualised) inflation dropped to 2.01, 3.11 and -2.14 per cent. This yielded a sharp decline in the year-on-year inflation to 6.49 per cent in December 2011 and further to 5.32 per cent in January 2012.
But after that, things haven't gone well. Point-on-point seasonally adjusted inflation, which is the thing to watch for in understanding what is happening every month, is back up to 8.22 per cent in January 2012 and 12.01 per cent in February 2012. Year-on-year inflation is back up to 7.57 per cent in February 2012.
A casual examination of the key graph (shown above) shows that the worst of double digit inflation seems to have ended. But we are not inside the target zone of 4 to 5 per cent, and neither are we likely to achieve this in the rest of this year. It would be unwise to declare victory over the inflation crisis, with this information set in hand.
Looking forward
Looking forward, there are two main problems worth worrying about. The first is the expectations of households. At the heart of India's inflation spiral is the problem that the man in the street has lost confidence that inflation will stay in the four-to-five per cent target zone. Survey evidence about household expectations has shown double digit values. This generates persistence of inflation; idiosyncratic shocks tend to not quickly die away. The mistrust of households is rooted in the lack of commitment to low and stable inflation at RBI, and this problem is not going to go away quickly. Despite all the problems faced in fighting inflation, RBI continues to communicate, through speeches and official documents, its lack of focus upon inflation.
The second problem is that of the exchange rate. Exchange rate depreciation feeds into tradeables inflation. With a large current account deficit, with policy impediments putting a cloud on capital inflows, rupee depreciation has taken place and may continue to take place. This would be inflationary. Indeed, if RBI chooses to cut rates on the 17th, there will be further weakening of the rupee (since the interest rate differential will go down thus deterring debt flows), which will further exacerbate tradeables inflation.
The media and financial commentators treat it as a given that on 17th, RBI will cut rates. However, the outlook on inflation is worrisome. India's inflation crisis, which began in 2006, has not ended. Year-on-year CPI-IW inflation has not yet got into the target zone of four-to-five per cent, nor is this likely to happen anytime soon.
Our thinking on this needs to factor in the general elections, which are looming at the horizon in May 2014. Given the salience of inflation in India for the poor, the ruling UPA coalition is likely to be quite concerned about getting inflation back to the informal target zone of four-to-five per cent, well ahead of elections. This also suggests that the time for hawkish monetary policy is now, so as to get inflation under control by mid-2013, well in time for elections in mid-2014.
A historical perspective
Inflation went out of control in 2006/2007 because RBI's pursuit of the exchange rate peg required very low interest rates at a time when the domestic economy was booming. (The capital controls that were then prevalent failed to deliver monetary policy autonomy; the only way to get towards exchange rate goals was through distortions of monetary policy). Given the lack of anchoring of household expectations, that inflation crisis has not yet gone away. Today, RBI is substantially finished with exchange rate pegging; we are mostly a floating exchange rate. In the future, inflationary expectations will not get unhinged owing to a pursuit of exchange rate policy by RBI. But while a pegged exchange rate pins down monetary policy, a floating exchange rate does not define monetary policy. RBI has yet to articulate what it wants to do with the lever of monetary policy. The first task for the lever of monetary policy should be the conquest of the inflation that is in our midst, owing to the monetary policy stance of 2006/2007.
In the early 1990s, unsterilised intervention in the pursuit of Rs.31.37 a dollar gave an inappropriate stance of monetary policy, which kicked off an inflation. Dr. Rangarajan wrestled it to the ground, even though the monetary policy transmission was weak then. In 2006, we ignited another inflation, once again owing to exceedingly low policy rates in the pursuit of exchange rate policy. Dr. Subbarao's challenge lies in wrestling this to the ground. His job is easier when compared with what Dr. Rangarajan faced, thanks to the progress which has taken place on financial reforms and capital account decontrol.
aren't we too lenient when we say that inflation should down to the comfort zone of 4-5%?
ReplyDeleteGiven the average inflation in the last 6 years has been upwards of 8-9%, isn't it the RBI / govt's duty to bring the inflation down to 2%, or maybe lower, for some time so that the common man can atleast afford what he could 6 years ago?
Is my thinking correct?
What is the optimal rate of inflation to target? In the models, lower inflation is always better, but I feel that to some extent, this is an artifact of the way the models are structured.
DeleteAs far as I know, the global convergence to the magic number 2%, as something that central banks should target, happened through thumb-rules and practical intuition. It doesn't easily drop out of the analytics.
In the global crisis, many central banks hit the zero lower interest bound: the policy rate can't drop below 0%. This forced them to be inventive and come up with schemes for quantitative easing and such like. This is a mess. I feel it's better to target 4% so as to have greater headroom away from 0, to further reduce the number of times per century that you have to resort to messy schemes.
Isn't it a problem if economies today can't handle deflation at all. Sure, liquidity trap and all is bad, lower growth in emerging countries is bad. But, is deflation bad in developed countries where growth really isn't needed all that badly as compared to developed economies? Of course its bad today with all the leverage - there is no option. But, why does economic theory call for an inflation target during normal times? Why isn't natural credit contraction ok? Bad creditors have to fail at some point in a business cycle, is it not? The technology sector has been undergoing immense deflation and that's not bad for the economy (in the context of developed economies), how does one factor that in?
DeleteI think you are thinking that there is some positive link between inflation and growth.
DeleteThe only time when a Philips curve fit the data was in the US in the 1960s. For the rest, increased inflation and increased inflation risk are damaging for growth. For a developing country, if you think the welfare consequences of low growth are really bad (e.g. social unrest in India at 4% growth while in the US 4% growth would be just fine) then you should be all the more passionate that in India, we should get to low and stable inflation, which is the best possible environment in which to obtain high and sustained GDP growth.
Deflation, though, is an entirely different beast. It is possible to get horrible things out of fairly reasonable models if you get deflationary expectations. E.g. why buy a toaster today when it'll be cheaper tomorrow?
Inflation targeting is a two way street: The central bank that has an inflation target of 4% fights to keep inflation from going up beyond 4%. It equally fights to prevent inflation from going down! This central bank will pull out all the stops to prevent inflation from dropping below target. Look at the US Fed today - they are targeting 2% and doing all sorts of unorthodox things in order to achieve this. If they didn't, the US today may be at 0% inflation or lower.
Are you sure "The only time when a Philips curve fit the data was in the US in the 1960s" ???
DeleteTo paraphrase Subramanian Swamy "learn some macroeconomics".
"If Chairman Bernanke were in the room, I would respectfully ask him why this persistent harking back to the Great Depression? It is one cyclical episode, but there are many others. I myself draw more instruction from the depression of 1920-21, a slump as ugly and steep in its way as that of 1929-33, but with the simple and interesting difference that it ended. Top to bottom, spring 1920 to summer 1921, nominal GDP fell by 23.9%, wholesale prices by 40.8% and the CPI by 8.3%. Unemployment, as it was inexactly measured, topped out at about 14% from a pre-bust low of as little as 2%. And how did the administration of Warren G. Harding meet this macroeconomic calamity? Why, it balanced the budget, the president declaring in 1921, as the economy seemed to be falling apart, “There is not a menace in the world today like that of growing public indebtedness and mounting public expenditures.” And the fledgling Fed, face to face with its first big slump, what did it do? Why, it tightened, pushing up short rates in mid-depression to as high as 8.13% from a business cycle peak of 6%. It was the one and only time in the history of this institution that money rates at the trough of a cycle were higher than rates at the peak, according to Allan Meltzer.
DeleteBut then something wonderful happened: Markets cleared, and a vibrant recovery began. There were plenty of bankruptcies and no few brickbats launched in the direction of the governor of the New York Fed, Benjamin Strong, for the deflation that cut an especially wide and devastating swath through the American farm economy. But in 1922, the first full year of recovery, the Fed’s index of industrial production leapt by 27.3%. By 1923, the unemployment rate was back to 3.2%. The 1920s began to roar." -- Jim Grant
Why don't economists of today, in the developed world, not conclude that a quick, perhaps deep deflation is exactly what the markets needed in 2008/2009/2010? Isn't it clear now in hindsight that if the decline would have been deeper (and more importantly debt was written off faster and in greater amounts), that the recovery would have been cleaner and not so fragile?
Oh I forgot, the lobbyists and corporate interests have too much control and people are wimps these days. People won't buy anything if prices fall - sure, they won't buy for some period of time (and perhaps they shouldn't be buying crap anyway), but then activity will come back at the end of the cycle as it always does and much of the excesses in the corporate world will be gone. What about this seemingly commonsensical, layperson argument do economists disagree with? And, then, isn't it the case that consumption does need to decline in the developed world. So, again, why are deflation and bankruptcies "horrible"?
In any case, seems like all the easing is leaking into emerging markets who can't take it anymore. The end game should be coming up quickly. It'll be fun to watch.
This is what I don't get about the toaster example: computers/tablets/mobiles and perhaps even toasters indeed have been getting cheap every year. I just don't see what horrible thing came out of that persistent deflation? It hasn't spelled disaster for electronics makers. Deflation in fact is a natural outcome of progress.
ReplyDeleteThe worry on debt flows is far more on the final outcome with GAAR, and similar steps into uncertainty taken by the Govt. than with a puny interest rate differential. The question the RBI faces today is not that if it should cut rates at all, but what happens to the investment cycle if it does not. To be sure, the responsibility of growth, inflation and a myriad other roles is something the central bank has taken it upon itself (and it need not, inflation targeting is good enough), but now that it has, there's little room in continuing with the current rate structure.
ReplyDeleteYou say inflation is not under control, and cite the CPI figures as an example. What about the WPI? Something the RBI professes to use? And there too, the so-called core-inflation is down to 5% levels, and the rest of the components, viz., primary and fuel, are not really in its control. I should perhaps put it better: demand for these items utilizes lower levels of financing than core inflation, and along with the rest of features (import-parity pricing of fuels, delayed pass-through, etc.), makes it difficult to be dealt with using conventional tools, which incidentally also do a lot of collateral damage.
This is the time to take hard decisions on supply--side dynamics in the economy, and not just depend on central bank rate economics to control inflation.
I heard you on inflation today (18-Apr) on CNBC. Enjoyed your opinion and was sinking quite well the way you explained bits.
ReplyDeleteYou mentioned that you do not buy gold in spite of the fact that you see inflation escalating with recent RBI move. Now for a layman like myself, investment in gold is the easiest way to protect your assets against inflation. Kindly explain what is a better way to prevent net asset value erosion from inflation.
Thanks
