Last week, the Planning Commission filed an affidavit in the Supreme Court updating the official poverty line to Rs 965 per month in urban areas and Rs 781 in rural areas. This works out to Rs 32 and and Rs 26 per day, respectively. The perceived inadequacy of these figures has led to widespread discussion and criticism in the media. In light of the controversy, it may be worth looking at where the numbers come from in the first place. Two Measures of the BPL Population The official poverty line is determined by the Planning Commission, on the basis of data provided by the National Sample Survey Organisation (NSSO). NSSO data is based on a survey of consumer expenditure which takes place every five years. The most recent Planning Commission poverty estimates are for the year 2004-05. In addition to Planning Commission efforts to determine the poverty line, the Ministry of Rural Development has conducted a BPL Census in 1992, 1997, 2002, and 2011 to identify poor households. The BPL Census is used to target families for assistance through various schemes of the central government. The 2011 BPL Census is being conducted along with a caste census, and is dubbed the Socio-Economic & Caste Census (SECC) 2011. Details on the methodology of SECC 2011 are available in this short Ministry of Rural Development circular. Planning Commission Methodology Rural and urban poverty lines were first defined in 1973-74 in terms of Per Capita Total Expenditure (PCTE). Consumption is measured in terms of a collection of goods and services known as reference Poverty Line Baskets (PLB). These PLB were determined separately for urban and rural areas and based on a per-day calorie intake of 2400 (rural) and 2100 (urban), each containing items such as food, clothing, fuel, rent, conveyance and entertainment, among others. The official poverty line is the national average expenditure per person incurred to obtain the goods in the PLB. Since 1973-74, prices for goods in the PLB have been periodically adjusted over time and across states to deduce the official poverty line. Uniform Reference Period (URP) vs Mixed Reference Period (MRP) Until 1993-94, consumption information collected by the NSSO was based on the Uniform Reference Period (URP), which measured consumption across a 30-day recall period. That is, survey respondents were asked about their consumption in the previous 30 days. From 1999-2000 onwards, the NSSO switched to a method known as the Mixed Reference Period (MRP). The MRP measures consumption of five low-frequency items (clothing, footwear, durables, education and institutional health expenditure) over the previous year, and all other items over the previous 30 days. That is to say, for the five items, survey respondents are asked about consumption in the previous one year. For the remaining items, they are asked about consumption in the previous 30 days. Tendulkar Committee Report In 2009, the Tendulkar Committee Report suggested several changes to the way poverty is measured. First, it recommended a shift away from basing the PLB in caloric intake and towards target nutritional outcomes instead. Second, it recommended that a uniform PLB be used for both rural and urban areas. In addition, it recommended a change in the way prices are adjusted, and called for an explicit provision in the PLB to account for private expenditure in health and education. For these reasons, the Tendulkar estimate of poverty for the years 1993-94 and 2004-05 is higher than the official estimate, regardless of whether one looks at URP or MRP figures. For example, while the official 1993-94 All-India poverty figure is 36% (URP), applying the Tendulkar methodology yields a rate of 45.3%. Similarly, the official 2004-05 poverty rate is 21.8% (MRP) or 27.5% (URP), while applying the the Tendulkar methodology brings the number to 37.2%. A Planning Commission table of poverty rates by state comparing the two methodologies by is available here.
The Monetary Policy Committee (MPC) has decided to conduct an off-cycle meeting today to discuss the failure to meet the inflation target under Section 45ZN of the Reserve Bank of India Act, 1934. As per the Reserve Bank of India Act (RBI), 1934, MPC is required to meet at least four times each year, to discuss the macroeconomic issues in the country, and take policy decisions to address those. This is the second time MPC has conducted an off-cycle meeting in 2022-23. The meeting is scheduled in light of inflation being consistently high for nine consecutive months.
In this blog, we discuss what the inflation targeting framework is, examine retail and wholesale prices, and the divergence between them.
What is the inflation targeting framework, and what happens if inflation is persistently high?
In 2016, Parliament amended the RBI Act, 1934 to change the monetary policy, and introduce an inflation targeting framework. This framework prioritises price stability to achieve sustainable GDP growth. Price stability allows investors to confidently invest their money for productive activities, without worrying about it losing value. Price stability also maintains the purchasing power of consumers, i.e., the ability to purchase a good (or service) with a given amount of money.
As per the new framework, the central government, in consultation with RBI sets: (i) an inflation target, and (ii) an upper and lower tolerance level for retail inflation. The target has been set at 4%, with an upper tolerance limit of 6% and a lower tolerance limit of 2%. The upper and lower limits indicate that although it is desirable for inflation to be close to 4%, deviation between these limits is acceptable. The target and bands are revised every five years. In March 2021, the existing targets were carried forward.
Retail inflation has been above 6% for the past nine months, and it has been above 4% from October 2019 onwards (See Figure 1).

If inflation is above or below the prescribed limits for three quarters, RBI must submit a report to the central government explaining why prices have been rising (or falling) persistently, what will be done to correct that, and an estimate as to when the target will be achieved.
The MPC uses tools such as interest rates to control the level of inflation in the economy. One such rate is the policy repo rate, which is the rate at which RBI lends money to banks. An increase in the policy repo rate makes borrowing money more costly, and hence is expected to control inflation by reducing the money supply. MPC increased this rate from 4% in April 2022 to 4.4% in May 2022, to 4.9% in June 2022, to 5.4% in August 2022, and to 5.9% in September 2022.
Breaking down the Consumer Price Index and the Wholesale Price Index
Consumer Price Index (CPI) measures the general prices of goods and services such as food, clothing, and fuel over time. Retail inflation is calculated as the change in the CPI over a period of time. Goods and services such as petrol, food products, health, and education are considered for its calculation, which are assigned different weights (See Table 1). Between February 2022 and August 2022, the average annual inflation was 6.9%. The rise in prices of subcomponents of the CPI during this period is indicated in Table 2.

CPI is not the only index that measures inflation in an economy. The Wholesale Price Index (WPI) measures the wholesale prices of goods. A change in wholesale prices reflects wholesale inflation. Table 3 indicates the weights assigned to goods for calculating the WPI. Manufactured goods include metals, chemicals, food products, and textiles.
Primary articles (23%) include food articles, and crude petroleum and natural gas. Fuel and power (12%) include mineral oils, electricity, and coal. WPI has remained above 10% from April 2021 onwards. It reached an all-time high of 17% in May 2022. This was driven by the inflation in metals, kerosene and petroleum coke, fruits and vegetables, and palm oil. |

Why has WPI inflation been consistently above CPI inflation?
Movements in the WPI have an impact on the CPI. For almost a year and half, CPI inflation has remained below WPI inflation. However, as per the design of the indices, it is expected that CPI would remain above WPI, and that any increase in WPI would reflect in the CPI after a time lag. This is because retail prices include taxes (as a percentage of price), while wholesale prices do not. Additionally, some of the goods in WPI act as inputs in the goods considered in CPI. An increase in input prices would lead to higher retail prices after a time lag.
We discuss possible reasons for why CPI has remained below WPI for a year and a half.

Composition of indices
As indicated in Table 2 and 3, the composition of the two indices varies. For instance, prices of manufacture of basic metals, chemicals, and machinery grew at an average rate of 13% between February 2021 and September 2022. They contribute 7% to the WPI. These are input goods for producing final goods and services such as automobiles, which are included in the CPI. The rise in prices of transport vehicles, communication devices, fuel for transport, and housing (CPI components) rose by 6% during this period.
The Ministry of Finance has observed that wholesale prices did not feed into retail prices (from March 2021 onwards) as wholesalers absorbed the rising input costs and did not pass them on to retailers. In August 2022, it noted that as retail prices are rising now, the pass-through may occur.
