WHOLESALE AND RETAIL PRICE TRENDS OF SELECT
COMMODITIES– DO THEY CONVERGE?
Inflation is a general measure of price changes that takes place between
two periods. When the measure of price rise widens beyond a commodity or a
commodity group to a heterogeneous mix of products/services, price indices are
constructed to get a single measure expressing in aggregate an inflation
number. The domain of inflation index, however, may differ depending upon
the set of economic agents or institutional units or set of commodities and
transactions.
1.2 In India, a variety of inflation indices are being construction. The WPI is
used extensively for short-term policy measures because it is the only index
that is available on a weekly basis with a time lag of two weeks from the
reference week and covers commodities across the entire real sector. A
number of Consumer Priced Indices are also constructed, which are class
specific, like Consumer Price Index for Industrial Workers (CPI-IW),
Agricultural Labourers (CPI-AL), Rural Labourers (CPI-RL) and Urban Non-
Manual Employees (CPI-UNME). All these indices are available on a monthly
basis with a time lag of 3-4 weeks and with commodity composition/weights
consistent with relative importance in expenditure of the respective
class/group. One comprehensive measure of inflation comes as an implicit
price deflector of gross domestic product (GDP). This is available on a
quarterly basis with a time lag of about a quarter.
1.3 In addition to the comprehensive price indices, monitoring of prices is
also undertaken by respective administrative Ministries/Departments for the
commodities within their domain. Department of Agricultural Cooperation
monitors the prices of agricultural commodities, Department of Chemical and
Petrochemicals monitors the prices of Drugs and Pharmaceuticals, Ministry of
Petroleum and Natural Gas monitors the prices of crude and related products,
3
and so on. The Department of Consumer Affairs monitors the prices of 14
commodities identified as essential commodities from the point of view of their
impact on vulnerable sections and as a measure of the cost of living of the
common people.
1.4 One major different between the price indices and prices monitored by
the administrative Departments is that while the former is a single aggregate
number, prices at the administrative Department level is for a single or
multiple products without any higher order aggregation. Both WPI and CPI,
however, are also amenable to be compiled at commodity and group level, but
they also permit higher order aggregation thorough specially constructed
weights. In the CPIs, the weights are assigned on the basis of the relative
importance of the item in the consumer expenditure of the class of consumers
to which the index pertains. In case of WPI, the weighting diagram follows
more or less a similar process, but weights are in terms of relative transaction
in the economy. The weighting diagram of WPI, however, is not drawn on the
basis of value added which is a concept in GDP. The weights are derived on the
basis of turnover or value of output. The ratio of value added to value of output
differs significantly in the real sectors. While this ratio is around 85% in
primary sectors comprising agriculture and mining, it is close to 21% in the
manufacturing sector. Assigned weights to sectors/groups in WPI which are in
terms of relative turnover, therefore, are not related to the relative share of
primary or manufactured products in GDP. A three stage approach has been
adopted in deciding weights of commodities in WPI.
a. At the first stage, the weights of three major groups (Primary
Articles, Fuel & Power and Manufactured Products) are decided on the
basis of the value of transaction. The value of transaction has been
worked out on the basis of value of output as obtained from National
Accounts and adjusted for international trade. The weights so assigned
4
are in proportion of the value of transactions and are, therefore, imposed
from above.
b. In second stage, the weights of the items at the broad group level
are decided. Within the three major groups, for the Primary Articles, the
weights for food articles, non-food articles and minerals; for the Fuel
group, weights for coal, minerals, oils and electricity; and for
Manufactured Products, weights at the two digit NIC classification of
the industrial groups level, are again imposed from above and are in
proportion of the value of transactions.
c. At the third stage, weights at commodity level are decided based
on the relative output of the selected commodities in such a manner that
the total weights of the commodities within a group would be equal to
the weights assigned at the broad group level.
1.5 For the agricultural commodities within the Primary Articles, weights
of the items are based on the presumed marketed surplus. While it is difficult
to say the share of the selected commodities to the total turnover of the
broad/major group, it is generally exhaustive. In the manufacturing group, in
the current series (1993-94) a traded value threshold of Rs.120 crore was set as
the parameter for selection of a commodity/product.
1.6 Given that the commodity basket and weights of commodities in WPI
and CPIs differ, it may not be uncommon for these indices to have different
inflation numbers. But since these measure (and generally believed as
indicating the level of prices and price rise), the difference in the inflation base
of these indices creates credibility gaps and apprehensions about the
information system. Further, the first point prices (or the prices at the
wholesale level) often are likely to lead the prices at the ultimate level of
transaction (at retail level). If the difference between two is due to margins
and other services getting imbedded into it, widening of divergence could be
5
considered as being arising due to hoarding or profiteering. There have,
therefore, been concerns that the wholesale and retail prices not only differ in
their levels but also in the direction and intensity. This paper, therefore,
makes an attempt, for the first time, to look at the wholesale and retail prices
of the 14 essential commodities covered by the Department of Consumer
Affairs. Geographic coverage of these commodities by DCA is also fairly
extensive and 17 locations are covered by daily price monitoring system.
1.7 The broad methodology followed as summarized below-
i) Both the retail and wholesale prices of 14 commodities have been
converted to a common base of 2004-05= 100. While wholesale
prices are average of the weeks, retail prices are of the month
end. As in the case of WPI, equal weights have been attached to
all the responses from17 locations. The issue to differences in
quality/variety has been ignored. Price relatives have, however,
been computed for each commodity/location for generating a
commodity/location specific RPI. In WPI also, each response is
given equal weights and index of a commodity is a simple
arithmetic average of price relatives of all responses.
ii) The commodities in retail price index have been assigned the
same weight as are being currently allocated in WPI 1993-94
series. This has been done for a better comparison. Further, it
may be capturing the relative importance of these commodities.
Weights that get assigned to the commodity groups are: food
grains (including atta)- 30.6 per cent; edible oils- 10.2 per cent;
and others- 49.2 per cent.
iii) A relative index is computed of the retail prices with reference to
the WPI to ascertain the divergence/convergence between WPI
and RPI.
iv) A comparison in the Retail Price Index (RPI) and WPI is made
both at commodity level and at the location level, besides the
comparison at the aggregate level of 14 commodities.
v) Relative index is also computed at the commodity level and at
location level for the retail prices with the WPI as the base.

Recent trends in Wholesale and Retail Prices at Commodity level
2.1 An aggregated RPI of 14 commodities increased from an average of 100
in 2004-05 to 144.1 in July 2009 recording a monthly increase of 0.56 per cent
(or an annualized inflation of 6.71 per cent). WPI of these commodities
increased to 136.9 in July 2009, giving an average monthly increase of 0.45 per
cent (or an annualized inflation of 5.37 per cent). Not only the overall RPI
increase was higher, the spread between the two indices continued to widen.
Average annual inflation of RPI was consistently higher than WPI, except in
the current year (first four months). (Table 1)

2.2 RPI relative to WPI increased to 105.3 in July 2009 indicating the
cumulative divergence in last little over 5 years. Relative index was less than
100 in 2004 and peaked in August 2008 and reached 108.8. Average monthly
rate of divergence in two indices was 0.11 per cent. Average annual index
indicated above, however, masks the inter month changes in the two indices.
Until around June 2007, both RPI and WPI have generally been close (though
a moderate shift became visible from June 2005) and then start to drift. Year
on year inflation measured either by RPI or by WPI were lowest during May-
December 2007 before witnessing an upsurge. Inflation reached double digit
7
levels in recent months. In April-July 2009, WPI inflation overtook inflation
measured in terms of retail prices. (Chart 1 and 2)

RPIWPI
2.3 There could be three reasons for widening of spread between RPI and
WPI of these 14 commodities. First, it could be because of an increase in the
transaction costs, like transportation. Second, it could be because of greater
services getting embedded into retail price, like home delivery, packaging,
cleaning, etc. Third, it could be due to institutional factors, covering
regulations, competition, entry restriction, etc. Directorate of Economics and
8
Statistics, Ministry of Agriculture had conducted a study of marketing
margins of agricultural produce in 2004-05 to see the share of producers in
prices paid by the consumers. The study observed wide inter-state and inter-
product variations in marketing margins and share of producers in retail
prices (Table 2). The study being a one time study does not provide any
evidence of increase in the spread. US Department of Agriculture, however,
have observed that the index of difference between the retail value and farm
value (1982-84=100) increased from 246.2 in 2006 to 282.2 in March 2009
(USDA- Agri Outlook Tables, July 2009). A study commissioned by the Office
of Economic Adviser for generating Trade Services Price Index observed that
the trade service price index for unorganized retail trade (excluding motor
vehicles) was flat between December 2007 and February 2008. The study
however observed increase in the index for organized retail during this period
by 13.8 per cent.

Tea 8.1 12.3 19.4 44.6 42.6 68.6
2.4 Increase in the spread between wholesale and retail prices beginning
2007-08 could also be attributed to increasing in “holding gains” and increase
in transaction costs. Increase in the domestic and international prices of “food,
fat and fuels” during this period was associated with tightening of monetary
9
policy (creeping increase in policy rates since October 2005 and until August
2008) and quantity restriction on stocks (since August 2006). Hardening of
interest rates necessitated the need for increasing the holding gains while the
quantitative stock restrictions requiring more frequent replenishment of
stocks increased transaction costs of business.
2.5 Measurement of distribution services could follow the National Accounts
framework. SNA 1993 framework states “although retailers actually buy and
sell goods, the goods purchased are not treated as part of their intermediate
consumption when they are resold with only minimal processing such as
grading, cleaning, packaging, etc. Wholesalers and retailers are treated as
supplying services rather than goods to their customers by storing and
displaying a selection of goods in convenient locations and making them easily
available to buy. Their output is measured by the total value of trade margins
realized on goods purchased for resale”. Share of “trade, hotels and
restaurants” in GDP, though has more than doubled from around 8 per cent in
1950-51 to 16 per cent in 2007-08, it has remained flat at 16 per cent during
2003-2008. As proportion to real sector GDP, it increased from 38 per cent in
2003-04 to 43 per cent in 2007-08. It is, however, difficult to say whether this
is due to greater services getting embedded into retail trade or increase in
margins per se.
Trends in WPI and RPI at commodity level
Food grains
3.0 Retail prices of cereals and pulses, accounting for a weight of 30.6 per
cent in the comparable basket, grew faster than their respective wholesale
prices. Average monthly increase in retail prices during April 2005 to July
2009 was around 0.8 per cent for cereals (including atta), 0.9 per cent for gram
dal 1.02 per cent for arhar. There were significant inter month and inter year
variations in the price changes. While grand al and wheat were the leading
contributors to inflation in 2005-07, arhar and rice witnesses a spurt in prices
10
in 2007-08 and 2008-09. Increase in wholesale prices of these products was
lower, though inter year and inter month variations followed more or less a
similar pattern. Average monthly increase in wholesale prices for these 5
commodities was, however, higher compared to increase at the aggregate level
of the comparable basket. A significant part of the increase in WPI could be
attributed to an increase in the minimum support price (MSP) of these
commodities. The MSP, by definition, sets the floor that is guaranteed to the
farmers. The index of MSP in 2008-09 with 2004-05 as the base was 152 for
paddy (common variety) and 159 for wheat and both RPI and WPI were in line
with the index of MSP.

3.1 Higher increase in retail prices of wheat and rice have also been due to
inclusion PDS in WPI. The current series of WPI has 8 responses for PDS rice
and 7 responses for PDS wheat out of total responses of 37 and 26 for rice and
wheat, respectively. PDS prices have remained unchanged since July 2002
and have moderated the increase in prices of wheat and rice to the extent of
proportion of PDS responses in WPI. Exclusion of the PDS component from
WPI considerably narrows the gap between WPI and RPI in both rice and
wheat. We are not looking at the issue of the treatment of subsidized items in
a price index, whether WPI or RPI, but simply looking at the comparability of
the two indices for the subsidized products. (Charts 4 and 5)

3.2 As expected the RPI relative to WPI has consistently been above 100 for
all the five commodities. Persistent and increasing divergence between RPI
and WPI was, however, observed for rice and arhar. Relative RPI for wheat
and gram dal peaked in 2006-07 resulting in relative inflation getting
moderated in last three years. Moderation in relative inflation of wheat is
largely due an upsurge in retail prices in 2006-07 on account of a poor crop in
2004-06. An increase in production from around 69 million tones in 2004-06 to
over 75 million tones in each of the successive three years kept a lid over the
retail prices. (Table 4)

Edible oils
4.0 Three edible oils forming part of the comparable basket accounted for a
10.2 per cent of the total weights. In edible oils, WPI and RPI generally appear
to be converging for mustard and ground nut oils. In case of vanaspati,
however, while RPI shows a decline in price levels from its peak in July 2008,
WPI is sticky. Inter month variations in both RPI and WPI as also the
inflation rates has been quite significant for edible oils. Both RPI and WPI
have been volatile. In case of edible oils, nearly half of the domestic
consumption is met through imports. Except for 2008-09 when Government
13
introduced a scheme of 1 million tones of imported edible oils at a subsidy of
Rs 15 per Kg, edible oils have had a market determined price regime. Impact
on domestic price of global price upsurge in 2007-09 was moderated through a
reduction of customs duties.
4.1 Average monthly increase in retail prices of edible oils varied from 0.3
per cent for Vanaspati to 0.6 per cent for mustard and groundnut oils. In case
of wholesale prices also, average monthly increase at 0.36 per cent was lower
compared to an increase of 0.6 per cent for mustard and groundnut oils. Retail
prices of edible oils started moderating from July 2008 onwards while
moderation in wholesale prices started happening a little later. Both for WPI
and RPI, the price levels in July 2009 were significantly lower than their
peaks. (Table 5)

4.2 Unlike the food grains, the RPI of edible oils relative to their respective
WPIs shows reasonable stability. Relative index in 2008-09 declines below 100
for Vanaspati. Near stability of RPI relative to wholesale prices is because
14
movement of index and inflation in both the series is generally on a similar
trend. (Table 6)

Department of Consumer Affairs are a heterogeneous mix. The price trends of
these commodities are also a heterogeneous mix. These commodities have a
weight of 59.2 per cent in the comparable basket. For three commodities,
sugar, milk and salt, average monthly increase in prices was higher for retail
prices. For the other three commodities, tea, potato and onions, average
monthly increase in prices was higher for wholesale prices.
5.1 RPI of sugar, potato and onions was most volatile. In case of sugar, RPI
reached a low of 88.2 in June 2007 before witnessing a continuous increase to
peak 147.3 in July 2009. Potato prices also fluctuated reaching a low of 75.7 in
February 2005 to a peak of 206.8 in July 2009. In fact, retail prices witnessed
an increase of over 100 per cent from February 2009 to July 2009 (RPI was
93.2 in February 2009). Onion prices were equally volatile and moved from a
low of 85.0 in April 2005 to a peak of 242.3 in October 2007. The movement of
wholesale prices over months was not altogether different. WPI of sugar
remained below 100 from May 2007 to March 2008 before a rally to reach the
current level of 136.5. Volatility in potato and onion prices was even sharper.
Movement of WPI of tea was also erratic. (Table 7)

5.2 Average monthly increase in retail prices varied from a low of 0.19 per
cent for sugar (though in the first four months of the current year sugar prices
increased by 51.1 per cent, low average monthly increase is due to the price
volatility) to 0.94 per cent for onions. Average monthly increase in wholesale
prices varied from a low of 0.16 per cent for sugar to a high of 1.15 per cent for
onions. (Table 7) Output and output expectations primarily contributed to
price volatility of these products. In case of sugar, global prices and availability
also increased the price volatility. Such volatility in agricultural of agro based
16
consumer products is not unusual, it is however, difficult to separate the effect
of output/output expectations and other factors on wholesale and retail prices.
It is also difficult to say whether the MSP of sugarcane and a regulated release
mechanism of sugar contributed to a generally uniform trend in wholesale and
retail sugar prices. Prices of milk, both at the wholesale and retail level
witnessed a steady increase.
5.3 RPI relative to the commodity specific WPI (Table 8) indicates that for
potato and onions, relative index has remained below 100 consistently since
2005-06. For tea also relative index declined below 100 in 2008-09. In case of
sugar, overall relative index was flat with relative monthly average inflation
(adjusted for increase in the wholesale prices of sugar) being 0.03 per cent.

5.4 Average monthly increase in retail prices generally exceeded the
wholesale prices, though divergence between the two rates differed across the
selected commodities. In general difference between these two rates of
inflation was higher for food grains and lower for edible oils and other
commodities. Price rise for 5 of the 14 commodities was higher in wholesale
17
segment compared to their retail prices. Month wise index of retail and
wholesale prices for each of the 14 commodities are indicated in Appendix 1.

5.5 Having examined the retail and wholesale prices for a common basket of
commodities, it may be important to look at whether WPI is a predictor of
retail prices. In order to test whether WPI is a good predictor, an attempt has
been made to construct RPIs relative to WPI such that the impact of price rise
in WPI will get reflected in RPI with a lag of 1 and 3 months. (Table 9) The
results, though mixed, show that average monthly increase in RPIs relative to
WPI increases with introduction of lag effect for some commodities and decline
for others. Reconstructed WPI increases monthly average inflation and
narrows the gap between retail and wholesale price build up. We also perform
the statistical Granger causality test. The result of pair wise causality test is
presented in Annex 1. The statistical test is generally consistent with our
18
earlier observation that WPI did not cause retail prices during the study
period 2004(April) to 2009 (July).
Spatial situation of WPI and RPI at select locations
6.0 An attempt has also been made to look at the retail and wholesale prices
at 17 different locations monitored by the Department of Consumer Affairs.
The methodology adopted for the comparison of retail and wholesale prices at
different locations is similar to the methodology adopted for comparison at the
commodity level. It has however been observed that Department of Consumer
Affairs does not get price responses for all commodities at all locations,
particularly wheat, groundnut oil and mustard oil are perhaps not covered at
certain location due to consumer preferences. A separate wholesale price index
has, therefore, been constructed for each location covering the commodities for
which retail prices are available and as such the two series are generally
comparable. As in case of the commodities, an attempt has also been made to
construct the retail price index relative to the reconstructed WPI, which is
location specific, and the overall RPI for all commodities (an average of all
locations). Location wise results are presented in the following section.
Shimla
6.1 The average monthly increase of retail prices in Shimla at 0.57per cent
was higher than the average monthly inflation measured in terms of WPI for
the comparable commodities. Though there were significant inter-month
variations in rate of inflation on annual basis, the inflation measured in terms
of RPI continued to be higher in most part of the study period (except 2007-08).
The rate of inflation in Shimla, however, was more or less in conformity with
the overall inflation measured in terms of RPI as an average of the 17
locations. The relative index continued to remain below 100 in 2005-08 and
average monthly increase in the relative price index was virtually zero.

6.2 The average monthly rate of inflation measured in terms of retail prices
at Lucknow was 0.64 per cent as against the overall inflation measured in
terms of WPI averaging 0.45 per cent. Retail price inflation consistently
remained above the inflation measured in terms of WPI. Lucknow also
witnessed inflation higher than the inflation for all locations with monthly
average rate of increase in the relative index (relative to overall RPI). On an
average, monthly price rise at Lucknow exceeded overall RPI inflation by 0.08
per cent. RPI relative to both WPI and in relation to the aggregate RPI

Delhi
6.3 Average monthly rate of inflation for Delhi measured in terms of RPI at
0.67 per cent higher than WPI. The inflation measured in terms of WPI for a
common commodity basket was 0.45 per cent, nearly two thirds of the monthly
increase of RPI. Inter-year variations of inflation also indicate that RPI
inflation continued to remain higher during the entire period. Further, the RPI
relative to the comparable WPI and aggregate RPI also remained above 100.
Increase in retail prices in Delhi was 0.11per cent higher on a monthly basis
relative to the overall increase in retail prices.

6.4 The Ahmedabad was one of the few locations where inflation measured
in terms of RPI at 0.44 per cent (average monthly built up) was close to the
average monthly built up of WPI (0.45per cent). Until 2008-09, RPI at
Ahmedabad was lower than WPI. Average annual inflation also turned
negative in 2007-08. However, from November 2008, retail prices started
witnessing a sharper increase and by July 2009, RPI was higher than WPI by
around 4 per cent. Compared to the overall RPI, inflation in Ahmedabad was
also lower with relative inflation (relative to the overall RPI) being -0.12 per
cent.

an average per month during April 2004-July 2009 were higher than the rate
of increase in wholesale prices for the comparable basket. Inflation also
remained consistently higher than WPI throughout this period. The city also
experienced retail price inflation, which was not only higher than the
comparable WPI, but it was also higher compared to the overall RPI. The

6.6 Though the inflation in Mumbai, measured in terms of retail prices
remained higher than the inflation measured in terms of comparable basket of
WPI, average monthly build up of inflation was lower when compared with
Delhi and Bhopal. The retail price inflation, however, remained consistently
higher than the inflation measured in terms of WPI. Relative to the overall
increase in retail prices, Mumbai witnessed an inflation which was 0.08 per

6.7 Both the retail and wholesale prices for the 14 commodities generally
moved in tandem in Jaipur. The overall RPI and WPI nearly converged and
there were no noticeable inter-year variations in the index, though average
annual rate of change in prices continued to differ. Further, the inflation was
lower compared to the overall inflation across all locations. The RPI of Jaipur
relative to the RPI of all locations remained consistently below 100 throughout

6.8 The price monitoring cell of Department of Consumer affairs captured
movement of retail prices of 12 of the 14 commodities. The prices of wheat and
groundnut oil were not being monitored may be because the consumer
preferences. For the comparable commodity basket, however, the average
monthly increase in retail prices at 0.54 per cent was higher than the average
monthly increase in the wholesale prices (0.43 per cent). In the first four
months of the current year, however, WPI inflation exceeded RPI inflation by a
wide margin. This narrowed the gap between the two indices in July 2009. The

Shillong
6.9 As in the case of Guwahaty, wheat and groundnut oil did not figure in
the commodity basket of retail prices in Shillong. While the WPI remained
consistently lower than RPI, near stable retail prices during October 2008 to
May 2009, narrowed the gap between the two indices. Average monthly
increase in retail prices at 0.52 per cent exceeded the increase recorded by
wholesale prices. The inflation measured in terms of RPI except for the current
year remained higher than WPI. As in the case of Guwahaty, Shillong also
witnessed overall inflation in retail prices lower than the inflation for all
locations with relative RPI remaining below 100 or close to that for most part
of 2004-09.

Aizawl
6.10 At Aizawl, the RPI did not include the prices of wheat, groundnut oil
and gram dal. The overall inflation measured in terms of RPI in Aizawl was,
however, one of the lowest with a negative spread of (-) 0.15 per cent between
average monthly retail and wholesale prices. The inflation relative to other
locations, therefore, was also in negative territory. RPI relative to both WPI
(comparable commodities) and average RPI remained below 100 for most part
of this period.

Patna
6.11 Average monthly rate of retail price increase at 0.68 per cent in Patna
was the highest of all the locations and nearly 2.5 times the average monthly
increase observed at Aizawl. It was only in the second half of 2008-09 and first
four months of the current year, rate of increase in retail prices was lower than
WPI and that narrowed the gap between RPI and WPI at Patna as also the
gap between its own RPI with the other locations. Relative RPI consistently
remained above 100.

Bhubaneswar
6.12 The commodity composition in Bhubaneswar for RPI was comparable
with the commodity composition in other locations in North-East Region.
Prices of wheat and groundnut oil were not being covered in view of the
consumer preferences. Bhubaneswar, however, witnessed a sharper increase
in retail prices compared to the increase in terms of WPI of the comparable
basket and also when compared with the increase in retail prices at other
locations in this region. Except for the 4 months of 2009-10 and 2004-05, the
retail prices grew at a rate higher than WPI. Relative to the other locations
(aggregated for all) inflation in Bhubaneswar was higher by 0.06 per cent on
average per month.

Kolkata
6.13 The commodity basket of retail prices did not include wheat at Kolkata.
A decline in the retail prices of the commodity basket during April-December
2008 considerably narrowed the gap between RPI and WPI. The inflation
measured in terms of RPI which was consistently higher than the WPI until
around April 2008 started ruling below the inflation measured in terms of WPI
in the recent period. The RPI relative to WPI and also relative to the overall
27
RPI declined below 100 in the first four months of 2009-10. While average
monthly increase of inflation measured in terms of RPI and WPI was virtually
close, relative inflation compared to aggregate RPI witnessed a decline at an
average rate of 0.11 per cent per month indicating that the changes in retail
prices at Kolkata were marginally lower than other locations.

Agartala
6.14 Agartala has the most restricted commodity basket of RPI as wheat,
groundnut oil and milk did not figure in the retail commodity basket covered
under price monitoring. While the exclusion of wheat and groundnut oil may
be on account of consumer preferences, the exclusion of milk may be linked to
the availability issue. For the comparable basket, however, rate of inflation
averaged 0.40 per cent per month for both the indices. In July 2009, RPI was
in fact lower than WPI by 6 points. The RPI relative to WPI and also as
compared with the RPI at other locations, however, consistently remained
below 100 indicating t5hat the average monthly build up of inflation in
Agartala was 0.16 per cent lower than the built up across all locations. This
may partly be due to the restricted commodity basket as average monthly
increase in retail prices for wheat and groundnut oil was higher than the
average of 14 commodities.

Hyderabad
6.15 Average increase in the retail prices of 14 commodities in Hyderabad
was 0.56 per cent per month as against an increase of 0.45 per cent for these
commodities in the wholesale markets. Inter-year variations in inflation
indicate that while the wholesale prices rose faster during 2006-08, retail
prices, however, witnessed upsurge in 2008-09 and in the first four months of
2009-10. RPI in Hyderabad relative to WPI and the RPI for all locations
continued to fluctuate but increased sharply in the first four months of the
current year. Overall average monthly increase in retail prices relative to
other locations, however, remained negative because of some initial
advantages.

Bengaluru
6.16 The index of wholesale and retail prices in Bengaluru continue to be
close until around 2007-08. However, in the next 16 months, there was a sharp
increase in the retail prices widening the gap between two indices. With that
the rate of inflation which virtually was close in both the series started
drifting. Average monthly increase in retail price index was 0.52 per cent
compared to an increase of 0.44 per cent in case of WPI. However,
notwithstanding the higher increase in RPI relative to WPI, average monthly
increase in the RPI, relative to the overall retail prices showed a lower growth
and relative index remained below or close to that throughout this period. In
most recent 16 months, however, RPI relative to other location increased by
3.5 per cent.

6.20 There are some interesting observations. Average monthly increase in
retail prices ranged between 0.27 per cent for Aizawl to 0.68 per cent at Patna.
The relative inflation in retail prices, relative to their respective WPIs had the
same pattern. There was hardly any difference in retail and wholesale prices
(in terms of an average monthly build up) at 5 locations and surprisingly two
of these were in the extreme north east region. Compared to the average RPI,
increase in retail prices were lower at 8 locations, with locations in north east
again dominating. While it is difficult to say that this is because the distances
of the consumption centers from producing centers have become less
important, but it does indicate some easing of supply bottlenecks, which
indeed are policy induced.
