Parliament passes an average of 60 Bills a year.  Each state legislature also passes a similar volume of legislation addressing an array of complex issues.  Bills cover subjects ranging from microfinance, land acquisition, and honour killings to the impact of pesticides on health.  Legislative matters have become increasingly more technical and require specialist inputs to be framed as effective public policy. Unlike other large democracies, legislators in India do not have access to institutional research support.  Access to formal information channels is normally available only to the Minister drafting the bill or to the select committee if the bill is referred to it. This deprives MLAs from participating in a more informed debate. Towards this end, PRS and the Indian School of Business (ISB) have initiated the first policy workshop of its kind for MLAs in India.  There is an emerging breed of proactive MLAs who are willing to seek out information to help them perform their role better. There are over 4000 MLAs in India, and a small group of MLAs in many states are showing this initiative.  They use the internet, consult specialists, and use resources like PRS to get updated or further information on issues affecting their state. About the Workshop The India Leadership workshop is for MLAs who want to be more effective legislators and assume positions of greater influence in state and national policymaking. This unique workshop is for rising stars who want to imbibe new approaches to policymaking and build professional networks with MLAs from different states.  The programme is led by distinguished faculty from internally reputed institutions including Harvard, IITs and IIMs. The three day workshop for progressive MLAs will be held at the campus of ISB in Hyderabad. Four such sessions will be held during the year, with the maiden edition being launched in January 2011.  Over the last five years, PRS has worked with MPs across all political parties to brief them on relevant issues for their work in Parliament.  MPs have recommended that MLAs also would benefit from similar research services. Ajit Rangnekar, Dean, Indian School of Business (ISB) says, “The ISB is committed to working with the Industry and the Government to help achieve national goals. We already have had a long track of engaging with public sector enterprises, and more recently with various government departments, in both executive education and research. We are now delighted to partner with the PRS Legislative Research to develop this programme targeted at capacity building among Indian Legislators. We believe that this ongoing interaction between the government and academia will strengthen our collective understanding of national priorities and spur collaboration for greater impact.”

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.
