How to measure inflation?
There are three ways
- WPI
- CPI
- GDP deflator
WPI
- Wholesale price index
- Compiled by Office of Economic Adviser ->Ministry of Commerce and Industry.
- Base year 2004
- Doesn’t cover services.
- it’s calculated using Laspeyres formula.
- Items are classified into three categories
- Primary articles
- Fuel, power, light, lubricants
- Manufactured products.
Earlier Government used to give weekly primary and food inflation data based on the Wholesale Price Index. But this practice has been discontinued since 2012.
CPI
- Consumer price index
- In 2011, the CPI system was reformed
| Before 2011 | After | |
| Subtypes | There were four subtypes of CPI
|
Now only three subtypes of CPI
|
| Prepared by |
|
All prepared by Central Statistical Organisation (CSO) -> Ministry of Statistics and Programme Implementation |
| Baseyear | Different years for different subtypes.
|
Common base year ( 2010) for all three subtypes. |
WPI vs CPI difference?
| WPI | CPI (reformed in 2012) | |
| Compiled by | Economic advisor | CSO |
| Ministry | Commerce ministry | Statistics ministry |
| Includes services? | No | Yes |
| Baseyear | 2004 | 2010 |
| Items included | 676 | 200 |
| Known as Headline inflation? | Yes | no |
| Importance | When RBI and Government make policies, they mainly pay attention to this number. | Not much |
GDP deflator
- GDP deflator is calculated by Central Statistical Organisation (CSO)-> Ministry of Statistics and program implementation.
- GDP deflator =GDP @current price divided by GDP @constant price
- GDP deflator is the most comprehensive number to measure inflation, but RBI /Government doesn’t use it much for policy making because GDP deflator data comes quarterly (and not weekly/monthly basis).
Measures to contain inflation
| By | How? |
| Government | Taxation, Expenditure, export bans etc. |
| RBI | Repo, SLR, CRR |
Steps taken by Government to curb inflation
Via import
- Govt reduced import duties for wheat, onions, pulses, and crude palmolein were reduced to zero
- Govt. allowed duty-free import of white/raw sugar.
- Govt. imported pulses and edible oils and distributed them at subsidized rate.
Via bans / coercive measures
- Govt. put ban on onion export for short periods of time whenever required
- Govt. suspended futures trading in rice, urad, tur, guar gum and guar seed.
- Govt. banned exports of edible oils (except coconut oil and forest-based oil) and edible oils.
- Govt. imposed stock limits on certain essential commodities such as pulses, edible oil, and edible oilseeds and rice.
- Increased excise duty on gold.
Via schemes
- Govt. has been giving rice and wheat to poor families at very cheap rate under the Antodyaya Anna Yojana.
- Govt. allocated huge amount of foodgrain under the targeted PDS (TPDS).
- government has allocated rice and wheat under the Open Market Sales Scheme (OMSS)
- direct cash transfer.
- Introduced Rajiv Gandhi Equity Saving scheme (with tax benefits) to make people invest money in it, rather than in gold.
Via Policy/Act
- Recently the government permitted FDI in multi-brand retail trading. This will improve logistical facilities connecting farmers with the final consumers and cut down the middlemen.
- The States of Madhya Pradesh and West Bengal have recently waived the market fee on fruits and vegetables. Such waivers are expected to promote investment private sector in the infrastructure necessary for transports and processing of fruits and vegetables.
- Budgetary provisions for improving storage and warehousing facilities, creating infrastructure for aquaculture etc.
Why Govt could not control inflation?
- From above points, it seems Government did lot of things to reduce inflation. Then why are we not seeing any good results?
Export bans = uncertainty
- Because, to fight food inflation, govt. started imposing ban on exporting some food commodities, increased and decreased the duties on import/export as necessary.
- While this may look a good solution for the short term but in long term, this creates uncertainty for businessmen, farmers.
- It reduces their incentive to produce more, because they’re not certain whether govt. will allow them to export or not? (for example Sugarcane->sugar, onion etc.)
- So indirectly, this affects employment and income of people => leads to more inflation.
Export bans = CAD
- When Government puts ban on export of xyz item, that means India receives that much less foreign exchange (dollars). So this increases the Current Account deficit (CAD).
- When CAD increases = rupee weakens against dollar = crude oil become expensive for us = inflation in everything.
Therefore, export bans are like firefighting / short term quickfix solutions. They donot solve the fundamental problems of Indian economy, infact they worsen it in long run.
Black money and gold purchase
- All Government schemes = leakage, corruption. And corruption =black money. And black money is mostly invested in gold and real estate.
- So demand of gold forever high= high current account deficit = rupee weakens against dollar= crude oil price increases = petrol/diesel price increases = even more inflation.
- Government did try to hike excise duty, make PAN cards mandatory for high value gold purchase and even thought of putting bans on gold import. But these moves have been heavily opposed by the jeweler lobby, hence Government has shied away from doing anything “radical” to stop the gold consumption.
- Besides a small hike of 2-3% in gold excise duty doesn’t prevent those bad guys with black money from buying gold! And Government hasn’t done much to stop the Black money / corruption either.
FDI and infra= No quick results
- You have read and heard this ten thousand times that FDI in multibrand retail = no middlemen = less inflation in food. And similarly cold storage, and food processing infrastructure= less wastage.
- But, suppose Government allows wallmart on Monday, that doesn’t mean from Tuesday Wallmart will start running and from Wednesday inflation will be gone. All these things take months and years to get file permission, construction, hiring and training employees, setting up supply lines etc.
Environmental clearances
- Many coal and mining projects are not cleared due to environmental issues.
- This has affected the electricity and raw material supply = input cost increased in manufacturing sector=inflation.
Fiscal consolidation
Government is on the path of “fiscal consolidation” so it increased the prices of petrol, diesel and reduced the number of subsidized LPG cylinders. These moves have increased the inflation.
Steps taken by RBI to curb inflation
Let’s do a recap: from SBI mananger’s point of view
| CRR | I’ve to keep this much cash aside. I cannot loan it to people. I donot earn any interest on this. |
| SLR | I’ve to invest this much cash in govt. securities, gold and reliable corporate bonds. |
| Repo | I’ve to pay this much interest rate, IF I take short term loans from RBI. |
| Reverse Repo | I earn this much interest rate, IF I deposit my money in RBI for short term. |
So what will be the impact on liquidity when RBI changes these rates?
| Rate | When rate is increased | When rate is decreased |
| CRR | Liquidity decreases | Liquidity increases |
| SLR | Liquidity decreases | Liquidity increases |
| Repo Rate | Liquidity decreases | Liquidity increases |
- Note: RBI doesn’t need to change reverse repo rate, because they automatically keep it 1% less than repo rate. (1%= 100 basis points).
- In winter, the supply of green vegetables is high so their price goes down. But in summer, their supply is low, so price goes high. Same is the link between liquidity and interest rates.
- When liquidity increases = loan interest rate decreases.
- When liquidity decreases = loan interest rate increases = harder to get loans for home, car, bike, business.
RBI focused its monetary policy on two objectives
- Control inflation.
- Facilitate growth.
- But It has been very difficult to do both these things at the same time. Because if RBI wants to control inflation, then it needed to reduce the liquidity= RBI had to increase repo rate, CRR. But this type of tight” monetary policy badly affects both producers (businessmen) and consumers. Why?
- But when repo rate is increased= liquidity decreased= difficult to get loans for home, car, bike etc.= demand down + difficult for businessmen to get loans = this hurts the businessman and whatever hurts the businessmen – also hurt the GDP and employment.
To put this in refined words: the tight monetary policy of RBI decreased the flow of
credit (loan) to productive sectors of Economy and hence negatively affected the growth.
- But due to inflationary pressures, RBI followed tight monetary policy during 2010-11.
- During this period, RBI raised policy rate (repo rate) by 3.75%= repo rate was increased from 4.75 per cent to 8.5 per cent. Check the following chart.

- But this move has backfired: global economy was progressing slow (due to problems in EU, and USA not yet fully recovered) => so, this tight monetary policy actually contributed to a sharper slowdown of Indian economy than anticipated.
- GDP growth rate fell down from good 9+% to around 5-6%.
CRR rates
Check the chart

As you can see, between 2010-11, here too, RBI kept increasing CRR rates to curb inflation. But from 2012 onwards, RBI has started decreasing the CRR.
SLR rates

As you can see, RBI hasn’t changed SLR much in last three years.
Why RBI couldn’t control inflation?
- We’re facing inflation because there is mismatch between supply and demand.
- Supply (of food, gold, houses, everything) is low
- While demand of those items (particularly food) is high (because population is high, the income levels of public has increased).
- Now think about this: What can RBI do? It can only increase the interest rates.
- While increased interest rates may decrease the demand of houses, cars, bikes but it cannot directly decrease the demand of food, milk and other essential commodities.
- In other words, Interest rates cannot change the dietary habits of people, not at least in the short term.
- Besides, high interest rates make it difficult for businessmen to borrow = less new projects = less new employment, less GDP.
- Therefore primary solution to fight India’s inflation =Increase the supply of food items.
- But this will requie thorough revision of the way govt. treats agriculture, allied activities, food processing and infrastructure. Small farms, disguised unemployment, heavy reliance on monsoon : all these issues must be addressed in comprehensive manner.
Way ahead
For RBI
- World Bank’s report (January 2013) says prices of most of the global commodity prices are expected decrease in 2013 and 14 (except for metals.)
- However, as per the assessment of RBI, global economic and financial conditions are still fragile. So they’re not providing any growth stimulus to the economy. (for example, if situation in Europe and America was good, they’d have been importing a lot more goods and services from India= India’s GDP could increase.)
- So in that context, even if RBI drastically reduces repo or CRR, that won’t do much good to economy.
For Government
- tackling the “supply side bottlenecks” take months and years.
- So in the mean time poor people must be protected from the inflation.
- That’s why govt. needs to continue giving welfare schemes and subsidies.
- But such support must be “targeted” to the right beneficiaries: that’s where UID/Aadhar, Direct cash transfer comes into picture.
- Other than that, Government needs to continue pushing for fiscal consolidation, deregulation of sugar pricing (as per Rangarajan’s recommendations), and other policy initiatives.
On a side note:
RESIDEX
- Rural to urban migration is an inevitable part of economic growth.
- But when people migrate from rural areas to urban areas, it creates pressure on civic amenities and housing (slums).
| Year | % of Indian population living in Urban areas |
| 1951 | 17 |
| 2011 | 30 |
| 2040 | 50 (expected) |
- Until recently, we did not have an index to capture the prices of residential buildings in urban areas.
- Hence “Residex” index was launched in 2007.
- This index records the changes in the prices of residential buildings.
- According to the RESIDEX, the housing prices have declined in Hyderabad, Banglore and Jaipur (from 2007 to 2012) but they have increased by more than 100% in Pune, Bhopal and Chennai.

Anyone reply please
According to me it should be BANK RATE as RBI lends money to commercial bank on repo rate by keeping their security paper and according to question RBI PURCHASE THE OTHER COMMERCIAL PAPER and its not security paper so it should be bank rate. what say??????????/
You are right. In bank rate commercial bill are given by bank to rbi and in repo and reverse repo, govt securities.

Hello Mrunal
Thanx for your wonderful efforts.
I am preparing for Upsc and have some doubts regarding economy for prelims.
Economy is my weakest link and as u can see not much time left to improve.
I have Ramesh Singh book but to cover the basics and then the current would take hell lot of time.
So what I want to ask is about your economy notes or PDFs…are they alone good enough for answering economy in pre???
It would be great if somehow I could attempt even 40-45% of economy questions askesd in pre.
Please guide

When liquidity increases = loan interest rate decreases.
When liquidity decreases = loan interest rate increases = harder to get loans for home, car, bike, business.
COULD YOU PLEASE EXPLAIN IT IN BRIEF
Hi,
LIQUIDITY INCREASES:
When liquidity increase -> more money is available in the market(for ex: Bank). Banks run business mainly by earnings from interests. If a bank keeps their interest rate very high, customers won’t approach it(because more money in market, they can get for less interest from some money lenders). So the banks are forced to keep the interest rates low. <>
LIQUIDITY DECREASES:
When liquidity decreases -> less money is available in the market(for ex: Bank). Money availability is less, so customers won’t have various means to get money(money lenders won’t have money to lend :-)). Banks can’t lend all the money with less interest(everyone will take the least available money and bank will with no money). so the Banks will increase the interest rate, which is not good for doing business, so customers taking loan will decrease. <>
Hope it helps.. :)
Mrunal, please correct this statement “In 2012, the CPI system was reformed” and “Before 2012” . The correct year is 2011.
About the new CPI – http://pib.nic.in/newsite/erelease.aspx?relid=69636
This chapter said that exempting vegetables and fruits from mandi fees will encourage development of backend infrastructure by private traders. Can you please explain how?
Hi Mrunal ji!
Can you please explain why WPI is caluclated only monthly, why not weekly or daily? What could its effect be if calculated on weekly basis as earlier?
@shilpa the reason is obvious as wpi involves too many items,so it wuld b difficult for the gov and also wld incur loss during collection.and secondly calculating it for greatrr time span gives an clear idea abt inflation..
Hi mrunal sir,
great work done by you..its so easy to understand..and getting lotzz of information
sir, there was given(in one of the economy material) that remedy for deflation is cutting down tax rates,lowering of central bank rates,increase in money supply,etc. and if these steps are followed wont the demand of goods and services further lower down? hoe can these measures be the solution for deflation? please clarify sir….
bhai………if money supply will increase .people living in that economy will b having more money & then they would be able to buy goods not only of neccessity but also they would be able to buy luxurious goods……this will increase demand of all type of goods….thus due to demand price of goods will increse & it will lead to inflation again
