The Government periodically
reviews and revises the base year
of the macroeconomic indicators as a regular exercise to capture structural
changes in the economy and improve the quality, coverage and representativeness of the indices. In this direction, the base year of All-India WPI has been revised
from 2004-05 to
2011-12 by the Office of
Economic Advisor
(OEA), Department of Industrial Policy and Promotion, Ministry of
Commerce and Industry to align it with the base year of other
macroeconomic indicators like
the
Gross Domestic Product (GDP) and
Index of
Industrial Production (IIP).
The
Wholesale Price Index (WPI) series in India has undergone six revisions in 1952-53, 1961-62, 1970-71, 1981-82, 1993-94 and 2004-05 so far. The current series is the seventh revision. The revision entails shifting the base year to 2011-12 from 2004-05, changing
the basket of commodities and
assigning new weights to the commodities. It has generally been the practice
to undertake the revisions on the advice of a Working Group constituted each time. For the new series with base 2011-12=100, a Working Group was
constituted on 19th
March 2012 chaired by Late
Dr. Saumitra Chaudhuri, Member, erstwhile Planning Commission and comprised most
stakeholders. The
composition and terms of reference of
the Working
Group is at Annex 1.
Key
Highlights
In
the revised series, WPI will continue to constitute three Major Groups namely
Primary Articles, Fuel
& Power and Manufactured Products.
Highlights of the changes introduced in the
new
series are summarized below:
•
Updated
item basket and
weighting structure conforming to
the structure of economy in 2011-12.
•
Increase in number of items
from
676 to 697. In all 199
new items have been added and 146 old items have been dropped.
•
The new series is
more representative with increase
in number of quotations from 5482 to 8331, an increase by 2849 quotations (52%).
New Features
•
In the new series of WPI, prices used for compilation do not include indirect taxes in
order to remove
impact of fiscal policy. This is in consonance with
international practices and will make the new
WPI conceptually closer to ‘Producer Price Index’.
•
A new “WPI Food Index” will be compiled to capture the rate of inflation in food items.
•
Seasonality of fruits
and
vegetables has been updated to account for more months as these are now available for longer duration.
•
Item level aggregates for new WPI are compiled using Geometric
Mean (GM) following international best practice and as is currently used for
compilation of All India CPI.
•
A high level Technical Review Committee has been set up for the first time
to carry out dynamic review process in order to keep pace with the
changing structure of the economy.

The
index basket of the new series has a total of 697 items including 117 items for Primary Articles, 16 items for Fuel &
Power and 564 items
for Manufactured Products.
Primary Articles
In
the Primary Articles, new vegetables and fruits such as Radish, Carrot, Cucumber, Bitter Gourd, Mosambi, Pomegranate, Jack Fruit, Pear etc have been added. In the
mineral group items like Copper Concentrate, Lead
Concentrate and Garnet have been added whereas Copper Ore, Gypsum,
Kaolin, Dolomite, Magnesite have been deleted. Natural Gas has been added
as
a new item.
Fuel and Power
In
the Fuel and Power Major Group, the index for non-coking coal will also be available at a disaggregated level based on Gross Calorific Value ( GCV)
to cater to the requirements of diverse user groups:
•
Non-Coking Coal G1 to G6 [GCV > 5500 Kcal/kg.]
•
Non-Coking Coal G7 to G14 [GCV 3100 Kcal/kg to 5500 Kcal/kg]
•
Non-Coking Coal G15 to G17 [GCV < 3100 Kcal/kg.]
The
item coke has been dropped.
The
index for electricity in the new series will be compiled as a single item in comparison
to the separate indices
according
to usage in agriculture, industry, domestic, commercial, and railways in 2004-05 series. In the new series, monthly
average rate of sale of
power of
49 selected generating
stations covering Hydro and Thermal sectors is being used to compile the index for
electricity.
In the Mineral oil sub-group, Light Diesel Oil has been deleted in view of its decreasing importance while Petroleum coke has been added as a new
item owing to its growing importance. There have been some changes in weights of the retained mineral fuels. The number of quotations has been increased
significantly to give wider geographical coverage.
Manufactured Products
A major review of manufactured products has been carried out. Accordingly,
the number of 2 digit groups has been increased from 12 to 22 in the new
series in keeping with National Industrial Classification (NIC) 2008. Around
173 new items like Conveyer Belt, Rubber Tread, Steel Cables, Tissue Paper, Wooden Splint, XLPE Compound have been added while 135
items like Khandsari, Papad, Video CD-Players, etc., have been dropped.
WPI Food Index
A new “Food
Index” is being
compiled combining the
“Food
Articles” under
“Primary
Articles” and “Food
Products” under
“Manufactured Products”. Together with the Consumer Food Price Index
released by
Central Statistics Office, this would help monitor the price situation of food items
better.
Technical Review Committee
In
order to address important technical issues such as substitution of source
of data,
change in specification of products and other data/methodological issues which require continuous review on a dynamic basis so that the new
WPI series remains
relevant till the
life of the
series, an institutional
mechanism has been established for the first time for facilitating seamless
substitution of dormant source, dynamic revision of
item list of products and the panel of factories through Technical Review Committee (TRC) chaired by Secretary, Department of Industrial Policy & Promotion. This committee
will
meet at least once a year for inter-alia recommending methodology for improving the coverage and quality of WPI like identifying new items that
need to be included in the item basket and removing those that have lost its
relevance or are no longer being produced. The composition of the TRC is at Annex 2.
Index numbers and Inflation rate
Based on the monthly price data provided by the source agencies the month- wise indices and inflation rates have been worked out. The monthly indices
for the
new
series with base 2011-12 from April 2012 through March 2017 at
the Major Group level are provided at Statement
I. The month-wise
comparative inflation rates at the Major Group level for the WPI series with base 2011-12 vis-à-vis 2004-05 are provided at Statement II. The annual average inflation
rates at the Major
Group level for both
the series are provided at Statement III.
Linking Factor
In
view of the conceptual and methodological difference between the 2004-05 and 2011-12 series, the estimate of linking factor will vary depending on the type of method used. Therefore, users are free to choose any method as
may be considered appropriate by them. However, as in the past, in order to
maintain
continuity in the time series data on wholesale price index, the
linking factor using the arithmetic conversion method for All Commodities
and the
three major groups of WPI are given in the Table below.

Major conceptual differences between WPI (2004-05) with WPI (2011-12)
Users of the new WPI series (base 2011-12) while comparing with the old
series may take note of the following conceptual differences:
a)
The item basket has been revised with inclusion of new items and
exclusion of old ones. Basket of commodities has been selected afresh in order to
capture the
structural changes
that have
occurred in the economy. As such, there may not be one-to-one
match for all the
commodities in the two series.
b) The number of 2 digit groups in Manufactured products has been increased from 12 to 22 in keeping with NIC- 2008.
c)
There has been
an increase
in number of
source agencies
in general across all Major
Groups. Dormant/closed sources have been removed.
d) Item level prices do not include indirect taxes.
Item level indices are
compiled using geometric mean (GM) whereas in the 2004-05
series arithmetic mean (AM) was used.
e)
The electricity sector is now a single item group that includes data relating to average rate of sale of power by
generating stations to distributors. In contrast, in WPI (Base 2004-05) retail level tariffs applicable to
different
sectors such as agriculture, industry, domestic, commercial and railways were used for compilation of WPI for electricity.
