HEAT AND CLIMATE CHANGE
1. Context
Climate change is reshaping Himachal Pradesh’s winter tourism, with declining snowfall, shorter seasons and extreme weather forcing hotel staff, guides, photographers and other workers to migrate to Goa, Leh-Ladakh and beyond in search of stable livelihoods, raising urgent questions about climate-resilient tourism policy.
2. What is Heat?
- In the context of microscopy, the temperature of an object reflects the average kinetic energy of its particles.
- When two objects at different temperatures come into contact, the cooler one will heat up while the warmer one cools down. Here, heat refers to the thermal energy exchanged between the objects to cause this change in temperature.
- On a larger scale, heat is treated as a type of energy with distinct properties, analyzed through thermodynamics, statistical mechanics, and related disciplines.
- A substance can take in heat at one location and release it at another, a principle that underlies many contemporary technologies such as thermal and nuclear power plants and air conditioning systems.
- Engineers have devised methods to transform heat into mechanical energy, enabling the creation of machines like the internal combustion engine
3. How is Heat Used?
- One of the best ways to grasp the concept of heat is by looking at its applications, such as internal combustion engines (ICEs) and thermal power plants.
- An ICE transforms heat into mechanical work, effectively applying the theoretical Carnot cycle, which defines the highest efficiency an engine can achieve in converting heat to work.
- The engine consists of four main components: a hot reservoir (with more heat), a cold reservoir (with less heat), an ideal gas between the reservoirs (transferring heat), and a piston next to the gas. Each cycle includes four stages.
- In the first stage, isothermal expansion, the ideal gas is insulated from the cold reservoir and exposed to the hot reservoir.
- Heat from the hot reservoir, produced for example by burning petrol, transfers to the gas, causing it to expand and push the piston. The second stage, isentropic expansion, continues the gas expansion while insulated from both reservoirs.
- The gas cools slightly as it does work on the piston without a temperature change due to insulation. These two steps involve the piston doing work on its surroundings.
- The third stage, isothermal compression, exposes the gas to the cold reservoir, where it releases its remaining heat.
- The piston moves downward in this stage. In the fourth stage, isentropic compression, the gas is again insulated from the reservoirs while the piston continues downward, compressing and warming the gas, readying it for the next cycle. In these last two steps, the surroundings work on the piston.
- Similarly, a thermal power plant consists of a boiler, turbine, generator, condenser, and pumps, with water as the working fluid. The ideal version of this system is the Rankine cycle, also comprising four stages.
- In the first stage, isentropic compression, a pump compresses the water to high pressure. During the second stage, heat addition, the water is pumped to the boiler and heated by an energy source, such as burning coal or nuclear fission, transforming it into saturated vapor under high pressure.
- The third stage, isentropic expansion, involves the pressurized vapor expanding in the turbine, releasing heat and reducing pressure. This expansion drives the turbine blades, generating power through the generator.
- In the final stage, heat removal, the cooled vapor enters the condenser, where it is condensed back to a saturated liquid at a fixed pressure. The condenser acts as a heat exchanger, using a coolant, such as cold water, to absorb the vapor's heat
4. How is heat related to work?
- Heat and work share the same physical dimensions, but not all heat can be converted into work. For instance, if a system performs work while losing thermal equilibrium, it will lose some energy.
- This can occur in an internal combustion engine (ICE) if, for example, it isn't well-lubricated, causing friction as the piston moves against the combustion chamber walls. This loss of 'useful heat' is tied to the concept of entropy, which indicates disorder in a system and prevents the associated heat from being converted into work.
- Additionally, when a system performs work without losing or gaining heat—such as during the isentropic expansion and compression steps of the Carnot cycle—the process is considered adiabatic. Fully adiabatic processes are reversible.
- Components of ICEs and thermal power plants are designed to alternate a medium that transports heat through different states, in steps that aim to maximize work output and minimize entropy changes and other energy losses
5.Applications of Heat
- Understanding the microscopic and macroscopic properties of heat has been vital in fields such as metallurgy and materials science, mining, refineries, various chemical reactions, semiconductor electronics, meteorology, and transportation.
- Heat plays a significant role in Heating, Ventilation, and Air-Conditioning (HVAC) systems. In many cold regions, heat is generated and transported from centralized facilities to homes and offices.
- Individual homes often use electric heaters, which convert electrical energy to heat by passing a current through a resistor, to stay warm. Recently, experts have advocated for a 'right to air-conditioning' for people in low- and middle-income countries facing extreme heat.
- Heat engines like internal combustion engines (ICEs) and steam engines operate on the Carnot cycle. Heat pumps, which are essentially air conditioners that heat rather than cool, use the reverse Carnot cycle.
- Air conditioners for cooling large spaces, such as halls and car interiors, utilize the reverse Rankine cycle.
- Other cycles, depending on the heat-transporting medium and desired operating conditions, include the Brayton, gas-generator, regenerative, Siemens, and Stirling cycles
6. Heat and Climate Change
- The global response to climate change is focused on two main strategies: mitigation and adaptation. For climate mitigation, researchers worldwide are developing new methods to generate heat energy without burning fossil fuels and finding ways to reduce emissions from existing technologies. Meanwhile, policymakers are working on new incentives to encourage the adoption of these solutions.
- In terms of climate adaptation, heat waves are a significant concern, especially in India. During a heat wave, the impact on health depends on the body's pre-existing health conditions and its ability to prevent heat accumulation.
- Long-term health is influenced by living conditions, access to clean environments, and healthcare. Short-term heat management depends on immediate measures to reduce heat buildup. When the wet-bulb temperature exceeds about 32 degrees Celsius, even brief periods of light outdoor activity can cause severe harm.
- Global warming itself is essentially a heat issue. Solar energy reaches the Earth, with some being reflected, some absorbed by the atmosphere, and some warming the ground. At night, the Earth emits this absorbed energy as infrared radiation.
- Greenhouse gases like carbon dioxide, methane, and water vapour absorb this radiation, convert it to kinetic energy, and heat the atmosphere, which reduces the Earth's ability to cool down efficiently
7. Way Forward
Addressing the role of heat in climate change requires a dual approach: mitigating the causes by reducing greenhouse gas emissions and adapting to the effects by improving our resilience to heat-related impacts. Both scientific innovation and policy action are essential to effectively manage heat in the context of climate change

INDIA'S LABOUR MARKET
1. Context
Every year, about 7-10 million young Indians enter the labour market. They are better educated than any generation before them — the average years of formal schooling for those aged 15 and above has reached 10 years nationally — and with hopes and expectations to match.The recently released Periodic Labour Force Survey (PLFS) 2025 report offers some key insights.
2. Recent trends in Employment
- India’s labour market indicators remain strong, with the Labour Force Participation Rate recorded at 59%, the Workforce Participation Rate at 57%, and unemployment at only 3%.
- Youth unemployment has shown a downward trend since 2024 in both rural and urban regions. In addition, successive Monthly PLFS reports during 2025 highlight a steady rise in women’s workforce participation.
- Rural female LFPR continued to improve through September 2025, reaching the highest level observed since May, indicating a consistent positive trend across multiple survey cycles.
- Employment quality has likewise improved over time. The proportion of workers engaged in regular salaried jobs increased from 22% to 24%, benefiting both men and women. At the same time, the share of self-employed workers declined from 58% to 56%.
- Since salaried employment generally offers greater income stability and social security benefits, this transition represents one of the most significant developments reflected in the 2025 labour data.
- Income patterns further support these improvements, especially for women workers. Earnings among women in regular salaried jobs rose by 7%, slightly higher than the 6% increase recorded for men.
- In self-employment, women’s earnings increased by 9% compared to 8% for men. Similarly, women engaged in casual labour witnessed a 5% rise in wages, whereas male wages in this category remained largely stagnant.
- Despite these gains, gender disparities in earnings continue to persist. Available data suggests that women receive nearly 76% of male earnings in salaried occupations, about 69% in casual work, and only 36% in self-employment.
- Although significant gaps remain, the growing movement toward salaried employment is gradually generating more meaningful economic benefits for women.
- Economic transformation is also reshaping employment patterns. Agriculture now accounts for 43% of total employment, while manufacturing and services contribute roughly 12% and 13%, respectively.
- Increasing numbers of young workers, especially women, are joining manufacturing and service industries.
- Moreover, occupational segregation based on caste and gender is less pronounced among younger generations than older ones, reflecting the long-term impact of improved educational access and greater social mobility, which are now contributing to more inclusive labour market outcomes
3. Gaps in Skills and Job Creation
- A major concern continues to be the transition from education to employment. India has greatly increased access to higher education, enabling students from a wider range of economic backgrounds to pursue tertiary studies.
- However, important gaps still persist. Between 2004 and 2023, nearly 5 million graduates entered the labour market every year, yet only around 2.8 million were able to obtain employment of any form.
- Insufficient access to structured skill development remains another obstacle. Merely 4% of people in the 15–59 age group have undergone formal vocational or technical training.
- At the same time, labour force participation among trained individuals is considerably higher — about 83% for men and 51% for women — highlighting the strong connection between skill acquisition and employment opportunities. This demonstrates the need to expand and strengthen skill-training initiatives on a much larger scale.
- Ensuring long-term participation of women in the workforce is another critical issue. While men outside the labour force mostly identified education as the reason for non-participation, women largely pointed to childcare and domestic responsibilities.
- This reflects deeper structural inequalities arising from the unequal burden of unpaid household work.
- For example, self-employed urban men work nearly 17.5 hours more per week than women, while among regular salaried employees the gap stands at roughly 7.9 hours weekly, illustrating the disproportionate dual burden of paid and unpaid labour carried by women.
- A further concern relates to the NEET population — youth who are neither in education, employment, nor training. Approximately one-fourth of individuals aged 15–29 belong to this category.
- Since they are excluded from official unemployment statistics, the scale of the issue often remains understated. If not addressed promptly, prolonged disengagement may push many young people into long-term detachment from the labour market
4. What is the Periodic Labour Force Survey (PLFS)?
- The Periodic Labour Force Survey (PLFS) is India’s main survey for understanding the condition of employment and unemployment in the country. It is conducted by the National Statistical Office under the Ministry of Statistics and Programme Implementation.
- The survey was introduced in 2017 to provide regular and reliable information about the labour market, replacing the earlier employment surveys conducted by the National Sample Survey Office.
- The need for PLFS arose because India’s economy and labour market were changing rapidly, but employment data was not available frequently enough.
- Policymakers required updated information to understand how many people were working, how many were unemployed, and how labour patterns were changing across rural and urban areas.
- To address this gap, PLFS was designed to provide both annual and quarterly estimates on employment-related indicators.
- The survey studies the participation of people in economic activities. It measures how many individuals are employed, how many are actively searching for work, and how many remain outside the labour force.
- Through this, it calculates important indicators such as the Labour Force Participation Rate (LFPR), Worker Population Ratio (WPR), and Unemployment Rate (UR). These indicators help in assessing the overall health of the economy and the availability of jobs.
- PLFS also provides detailed insights into the nature of employment in India. It classifies workers into categories such as self-employed persons, regular salaried employees, and casual labourers.
- This distinction is important because different forms of employment offer different levels of income security, social protection, and job stability. For example, regular salaried employment is generally considered more secure than casual labour.
- Another important feature of PLFS is that it captures differences across gender, age groups, education levels, and regions.
- It highlights issues such as women’s participation in the workforce, youth unemployment, rural–urban disparities, and shifts in employment from agriculture to manufacturing and services. Because of this, the survey has become an essential tool for analysing structural changes in the Indian economy.
- The survey uses different approaches to measure employment status. The “Usual Status” method examines a person’s employment situation over a longer reference period, while the “Current Weekly Status” method looks at whether a person worked for at least one hour during the previous seven days. These methods help provide a broader and more accurate picture of employment conditions.
- Today, PLFS serves as the most important official source of labour market data in India. Governments, economists, researchers, and policymakers rely on it to formulate employment policies, assess economic performance, design welfare programmes, and evaluate the impact of reforms on workers and livelihoods

Female Labour Force Participation (FLFP)
Female Labour Force Participation (FLFP) refers to the proportion of women in the working-age population who are either employed or actively seeking employment. In simple terms, it measures how many women are participating in economic activities within a country. It is usually expressed through the Female Labour Force Participation Rate (FLFPR), which indicates the percentage of women who are part of the labour force compared to the total female population within a specified age group. Women who are working in jobs, self-employment, farming, business activities, or even looking for work are included in the labour force. However, women who are neither working nor searching for employment are considered outside the labour force. Female labour force participation is considered an important indicator of economic development, gender equality, and social progress. A higher participation rate generally reflects better access to education, employment opportunities, skill development, mobility, and financial independence for women. It also contributes to higher household incomes, poverty reduction, and overall economic growth. In India, female labour force participation has traditionally remained lower than that of men due to several social, cultural, and economic factors. Many women are engaged in unpaid domestic work such as childcare, cooking, and household responsibilities, which are not counted as economic activities in official surveys. Other factors such as lack of safe transportation, limited access to formal jobs, wage inequality, social norms, and interruptions caused by marriage or motherhood also affect women’s participation in the workforce. |
5. Way Forward
The PLFS 2025 findings indicate that India’s labour market is showing signs of positive progress. Nevertheless, converting these improvements into sustained, productivity-driven economic growth will require focused policy measures. This includes expanding industry-oriented skill development programmes, promoting women’s participation in the workforce through gender-sensitive policies, and creating stronger access to secure employment supported by broader social protection systems and greater emphasis on green industries. In addition, specialised initiatives such as apprenticeship programmes will play an important role in bringing NEET youth back into productive economic activity

SOUTHWEST MONSOON
1. Context
The southwest monsoon is expected to advance into Kerala on May 26, the India Meteorological Department (IMD) said on Friday. The “normal” date for the monsoon’s advent over the State is June 1.
2. What is the southwest monsoon?
- The southwest monsoon is a seasonal weather pattern that brings significant rainfall to large parts of South Asia, particularly India, between June and September
- The southwest monsoon typically begins in early June and lasts until late September. It starts with the arrival of the monsoon winds in the southern part of India, usually marked by the onset over the state of Kerala
- The southwest monsoon brings about 70-90% of India’s annual rainfall. The distribution of rainfall varies, with some regions receiving heavy rains, while others may experience scanty showers.
- The Western Ghats, the northeastern states, and the Himalayan foothills typically receive very heavy rainfall.
- The monsoon is critical for the Kharif crop season in India, which includes crops like rice, maize, pulses, and cotton. Adequate and timely monsoon rains are essential for a good harvest
- The monsoon starts retreating from northwestern India in early September and completely withdraws from the Indian subcontinent by mid-October. This phase is also known as the retreating or northeast monsoon
Mechanism:
- High-Pressure Area: During the summer, intense heating of the landmass in the Indian subcontinent creates a low-pressure area over northern India and the Tibetan Plateau.
- Low-Pressure Area: The Indian Ocean remains relatively cooler, creating a high-pressure area.
- Wind Movement: Air moves from the high-pressure area over the ocean to the low-pressure area over the land, carrying moisture from the ocean and resulting in rainfall.
The monsoon trough is an elongated area of low pressure extending from the heat low over Pakistan and northwestern India to the Bay of Bengal. It influences the distribution and intensity of the monsoon rains.
3. What are easterly and westerly winds?
Easterly Winds
- Easterly and westerly winds refer to the direction from which the winds originate
- Easterly winds are winds that blow from the east towards the west
- Easterly winds can affect weather patterns, including the development of tropical storms and cyclones. For instance, easterly waves in the tropics can lead to the formation of tropical cyclones in the Atlantic and Pacific Oceans
Characteristics:
- Trade Winds: One of the most well-known examples of easterly winds are the trade winds. These winds blow from the east towards the west in the tropics, from the subtropical high-pressure areas toward the equatorial low-pressure areas.
- Tropical Regions: In the tropical regions, particularly between 30 degrees north and south of the equator, easterly winds are prevalent. These are crucial for the weather patterns and climatic conditions in these regions.
- Monsoon Winds: During certain seasons, such as the northeast monsoon in India, easterly winds play a significant role. These winds bring dry air from the land towards the ocean during the winter months.
Westerly Winds
- Westerly winds are winds that blow from the west towards the east
- Westerly winds play a significant role in the weather of temperate regions, influencing the climate and the movement of storm systems.
- They are also responsible for carrying warm and moist air from the oceans inland, affecting precipitation patterns in coastal and inland regions.
- The westerlies can affect transoceanic travel and weather prediction due to their influence on the movement of high and low-pressure systems
Characteristics:
- Prevailing Westerlies: These winds are predominant in the mid-latitudes (between 30 and 60 degrees north and south of the equator). They blow from the subtropical high-pressure belts towards the poles.
- Jet Streams: High-altitude westerly winds known as jet streams are important in influencing weather patterns and the movement of weather systems across the globe. They are fast flowing and occur in the upper levels of the atmosphere.
- Polar Front: In the mid-latitudes, the westerlies interact with polar easterlies near the polar front, leading to the development of extratropical cyclones and storms

4.How does monsoon occur in India?
Monsoons in India occur due to seasonal changes in wind patterns and temperature differences between land and sea.
Here's a concise explanation of the process:
- Differential heating: During summer, the Indian landmass heats up more quickly than the surrounding Indian Ocean.
- Low pressure system: The heated land creates a low-pressure area over the Indian subcontinent.
- Wind direction shift: This low pressure draws in moisture-laden winds from the cooler Indian Ocean towards the land.
- Orographic lift: As these winds encounter geographical features like the Western Ghats or the Himalayas, they are forced to rise.
- Condensation and precipitation: The rising air cools, causing water vapor to condense and form clouds, leading to heavy rainfall.
- Duration: This pattern typically lasts from June to September, bringing the majority of India's annual rainfall.
5.What are the conditions that determine the onset of monsoon?
- The primary driver is the temperature difference between the land and the surrounding sea. During summer, the land heats up faster than the ocean, creating a low-pressure area over the land and a high-pressure area over the ocean. This pressure difference leads to the movement of moist air from the ocean to the land
- Warm sea surface temperatures are crucial as they increase the evaporation rate, contributing to the formation of moist air masses that drive the monsoon rains.
- The monsoon winds, which are part of the larger atmospheric circulation, shift according to the seasonal temperature differences. The southwest monsoon, for instance, is driven by the southwest winds that carry moisture from the Indian Ocean to the Indian subcontinent.
- The geographical features, such as mountain ranges, play a significant role. For example, the Western Ghats in India force moist air to rise, cool, and condense, leading to heavy rainfall on the windward side
- The movement and strength of the high-pressure systems over the oceans and low-pressure systems over the land influence the intensity and timing of the monsoon.
- Phenomena such as El Niño and La Niña can affect the strength and timing of the monsoon. For example, El Niño can lead to weaker monsoons due to altered wind patterns and sea surface temperatures
6.What is the impact of La-Nina and El Nino on monsoon?
La Niña and El Niño, both phases of the El Niño-Southern Oscillation (ENSO) phenomenon, have significant impacts on the monsoon patterns around the world.
Here’s how each affects the monsoon:
El Niño
- El Niño is generally associated with a weaker Indian monsoon. The warming of the central and eastern Pacific Ocean during El Niño tends to disrupt the normal atmospheric circulation patterns, leading to reduced rainfall over the Indian subcontinent.
- The onset of the monsoon can be delayed, and the overall intensity of the rainfall during the monsoon season might be lower than usual
- El Niño often brings drier conditions to Southeast Asia and northern Australia, leading to droughts and reduced rainfall
- Eastern and southern Africa may experience drier conditions as well
La Niña
- La Niña, characterized by cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean, is typically associated with a stronger Indian monsoon. It often leads to increased rainfall over the Indian subcontinent
- The enhanced monsoon can lead to heavier rains and potentially more frequent and intense flooding
- La Niña tends to bring wetter conditions to Southeast Asia and northern Australia, potentially causing heavy rains and flooding
- La Niña can lead to wetter conditions in parts of northern South America

MINIMUM SUPPORT PRICE
1. Context
The Iran crisis-induced supply shock in fertilisers and a below-normal monsoon may give a boost to bajra, moong and other pulses. MSP procurement by the government can also help.
2. What is the Minimum Support Price (MSP)?
.png)
- MSP is the minimum price a farmer must pay for their food grains as guaranteed by the government. They are recommended by the Commission for Agricultural Costs and Prices (CACP) and approved by the Cabinet Committee on Economic Affairs.
- The CACP submits its recommendations to the government in the form of Price Policy Reports every year.
- After considering the report and views of the state governments and also keeping in view the overall demand and supply situation in the country, the central government takes the final decision.
- The Food Corporation of India (FCI) is the nodal agency for procurement along with State agencies, at the beginning of the sowing season.
The minimum support price (MSP) is set for 22 crops every year. They include:
- 7 cereals (paddy, wheat, maize, bajra, jowar, ragi, and barley)
- 5 pulses (chana, tur/arhar, moong, urad, and Masur)
- 7 oilseeds (rapeseed-mustard, groundnut, soya bean, sunflower, sesamum, safflower, and Enigerseed) and
- 4 commercial crops (sugarcane, cotton, copra, and raw jute).
3. How MSP is Calculated?
- MSP, presently, is based on a formula of 1.5 times the production costs.
- The CACP projects three kinds of production costs for every crop, both at state and all-India average levels.
- A2 covers all paid-out costs directly incurred by the farmer — in cash and kind — on seeds, fertilizers, pesticides, hired labour, leased-in land, fuel, irrigation, etc.
- A2+FL includes A2 plus an imputed value of unpaid family labour.
- C2: Estimated land rent and the cost of interest on the money taken for farming are added to A2 and FL.
- Farm unions are demanding that a comprehensive cost calculation (C2) must also include capital assets and the rentals and interest forgone on owned land, as recommended by the National Commission for Farmers.
4. The issue with the calculation of MSP
- To calculate MSP, the government uses A2+FL cost. The criticism of A2+FL is that it doesn’t cover all costs and that a more representative measure, C2, needs to be used.
- For example, in the 2017-18 rabi season, CACP data shows that C2 for wheat was 54% higher than A2+FL.
- The Swaminathan Commission also stated that the MSP should be based on the comprehensive cost of production, which is the C2 method.
5. Key Points about the Farmer's Demand
- After the recent decision to repeal three contentious farm laws, protesting farmer unions are now pressing for their demand of the legalization of the Minimum Support Price (MSP).
- They want a legal guarantee for the MSP, which at present is just an indicative or a desired price.
- Legalising MSPs would put the government under a legal obligation to buy every grain of the crops for which MSPs have been announced.
- At present, the PM has announced the formation of a committee to make MSP more transparent, as well as to change crop patterns and to promote zero-budget agriculture which would reduce the cost of production.
- The entire issue of enforcing MSP legally is a tricky, complicated, and multidimensional one, involving lots of factors.
- Core demand: MSP based on a C2+50% formula should be made a legal entitlement for all agricultural produce. This would mean a 34% increase in the latest MSP for paddy and a 13% increase for wheat. MSP should also be extended to fruit and vegetable farmers who have been excluded from benefits so far.
6. The rationale behind the demand for legislation of MSP
- Farmers receive less than MSP: In most crops grown across much of India, the prices received by farmers, especially during harvest time, are well below the officially declared MSPs. And since MSPs have no statutory backing, they cannot demand these as a matter of right.
- Limited procurement by the Govt: Also, the actual procurement at MSP by the Govt. is confined to only about a third of wheat and rice crops (of which half is bought in Punjab and Haryana alone), and 10%-20% of select pulses and oilseeds. According to the Shanta Kumar Committee’s 2015 report, only 6% of the farm households sell wheat and rice to the government at the MSP rates.
7. Challenges associated with MSP
- Protest by Farmers: Farm unions have been protesting for more than six months on Delhi's outskirts, demanding legislation to guarantee MSP for all farmers for all crops and a repeal of three contentious farm reform laws.
- MSP and Inflation: When announcing the MSP, inflation should be taken into account. But often the price is not increased up to the mark. For example, this time MSP for Maize has not even considered inflation then how it will benefit farmers! Also, frequent increases in the MSPs can lead to inflation too.
- High Input Costs: The input costs have been rising faster than sale prices, squeezing the meagre income of the small farmers and driving them into debt.
- Lack of Mechanism: No mechanism guarantees that every farmer can get at least the MSP as the floor price in the market. So proper mechanisms need to be fixed for all times to come.
- Restriction in Europe: Even after producing surplus grains, every year a huge portion of these grains gets rotten. This is due to the restrictions under WTO norms, that grain stocks with the FCI (being heavily subsidized due to MSP) cannot be exported.

RETAIL INFLATION
1. Context
Retail inflation quickened to a 13-month high of 3.5% in April 2026, although still coming in lower than what was expected by most economists. The price rise was largely driven by higher food inflation as well as higher prices at restaurants as they passed on higher fuel prices to consumers.
2. What is Inflation?
- It is the rise in prices of goods and services within a particular economy wherein consumers' purchasing power decreases, and the value of the cash holdings erodes.
- In India, the Ministry of Statistics and Programme Implementation (MoSPI) measures inflation.
- Some causes that lead to inflation are demand increases, reduction in supply, demand-supply gap, excess circulation of money, increase in input costs, devaluation of the currency, and rise in wages, among others.
3. Retail Inflation
Consumers often directly buy from retailers. So, the inflation experienced at retail reflects the actual price rise in the country. It also shows the cost of living better. In India, the index that reflects the inflation rate at the retail level is known as Consumer Price Index (CPI). Unlike WPI, CPI includes both goods and services. CPI is used to calculate the Dearness Allowance (DA) for government employees.
4. How Inflation is measured?
- In India, inflation is primarily measured by two main indices- WPI (Wholesale Price Index) and CPI (Consumer Price Index), Which measures Wholesale and retail-level price changes, respectively.
- The CPI calculates the difference in the price of commodities and services such as food, medical care, education, electronics, etc, which Indian consumers buy for use.
- On the other hand, the goods or services sold by businesses to smaller businesses for selling further are captured by the WPI.
- Both WPI (Wholesale Price Index) and CPI (Consumer Price Index) are used to measure inflation in India.
5. What is the Inflation Target?
- Under Section 45ZA, in consultation with the RBI Act, the Central Government determines the inflation target in terms of the Consumer Price Index (CPI), once in five years and notifies it in the Official Gazette.
- Accordingly, on August 5, 2016, the Central Government notified in the Official Gazette 4 percent Consumer Price Index (CPI) inflation as the target for the period from August 5, 2016, to March 31, 2021, with the upper tolerance limit of 6 percent and the lower tolerance limit of 2 percent.
- On March 31, 2021, the Central Government retained the inflation target and the tolerance band for the next 5-year period-April 1, 2021 to March 31, 2026.
- Section 45ZB of the RBI Act provides for the constitution of a six-member Monetary Policy Committee (MPC) to determine the policy rate required to achieve the inflation target.
6. Monetary Policy Committee (MPC)
- The MPC is a statutory and institutionalized framework under the RBI Act, of 1934, for maintaining price stability, keeping in mind the objective of growth. It was created in 2016.
- It was created to bring transparency and accountability in deciding monetary policy.
- MPC determines the policy interest rate required to achieve the inflation target.
- The committee comprises six members and Governor RBI acts as an ex-officio chairman. Three members are from RBI and three are selected by the government. The inflation target is to be set once every five years. It is set by the Government of India, in consultation with the Reserve Bank of India.
- The current inflation target is pegged at 4% with -2/+2 tolerance till March 31, 2021.
7. What Caused the drop in Inflation?
- Retail Inflation or price gains based on the Consumer Price Index, slowed to 6.77 % last month, from September's 7.41%, aided by an appreciable deceleration in food price inflation.
- The year-on-year inflation based on the Consumer Food Price Index eased by almost 160 basis points in October, to 7.01%, from the preceding month's 8.60%, helped by a 'decline in prices of vegetables, fruits, pulses and oils, and fats', the Government said.
- With the food and beverages sub-index representing almost 46% of the CPI's weight, the slowdown in food price gains understandably steered overall inflation lower even as price gains in three other essential categories, namely clothing, and footwear, housing, and health remained either little changed from September or quickened.
- Inflation at the Wholesale Prices Level also continued to decelerate, with the headline reading easing into single digits for the first time in 19 months. A favorable base effect along with a distinct cooling in international prices of commodities including crude oil and steel amid gathering uncertainty in advanced economies was largely instrumental in tempering wholesale price gains.
8. Recent Measures by the Government
To soften the prices of edible oils and pulses, tariffs on imported items have been rationalized from time to time. The stock limits on edible oils are also maintained, to avoid hoarding.
The Government has taken trade-related measures on wheat and rice to keep domestic supplies steady and curb the rise in prices.
The impact of these measures is expected to be felt more significantly in the coming months.
