It reflects a decrease in purchasing power, meaning each currency unit buys fewer goods and services. As inflation rises, each unit of currency buys fewer goods and services, effectively decreasing the purchasing power of money.<\/span><\/p>\r\n<p><span style=\"font-weight: 400\">Economists typically measure inflation as an annual percentage change in a price index, such as the Consumer Price Index (CPI) or the Gross Domestic Product (GDP) deflator.<\/span><\/p>\r\n<h2><span style=\"font-weight: 400\">Inflation Meaning<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Inflation is a gradual loss of purchasing power that results in a significant increase in the prices of goods and services over time. The inflation rate is calculated by averaging the price increases of a basket of selected goods and services over a year. High inflation means that prices are rising rapidly, whereas low inflation means that prices are rising more slowly.\u00a0<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Deflation<\/b><span style=\"font-weight: 400\">: Inflation can be distinguished from deflation, which occurs when prices fall while purchasing power rises.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation Types<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Inflation is categorised based on the rate and causes of price increases. By rate, it includes creeping, walking, galloping, and hyperinflation. By causes, it comprises demand-pull, cost-push, structural, and protein inflation.<\/span><\/p>\r\n<h3><span style=\"font-weight: 400\">Types of Inflation Based on Rate<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">Inflation is categorised by the rate at which prices increase. Based on rate, inflation can be classified as creeping inflation, walking inflation (Trotting Inflation), galloping inflation (Hopping or Running Inflation), or hyperinflation.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Creeping Inflation (Mild or Low Inflation): <\/b><span style=\"font-weight: 400\">A gradual increase in prices, usually less than 3% annually, which is considered manageable and may positively stimulate demand and investment.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Walking Inflation (Trotting Inflation): <\/b><span style=\"font-weight: 400\">Prices increase at a moderate pace, generally around 3% to 10% per year. If unchecked, it can lead to economic overheating.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Galloping Inflation (Hopping or Running Inflation): <\/b><span style=\"font-weight: 400\">This inflation occurs when prices increase rapidly at double\u2014or triple-digit annual rates, between 10% and 50%. It disrupts economic stability and can severely affect consumer purchasing power.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Hyperinflation: <\/b><span style=\"font-weight: 400\">An extreme form of inflation where prices rise over 50% monthly. Hyperinflation can decimate a currency\u2019s value, as seen historically in Zimbabwe and Germany\u2019s Weimar Republic.<\/span><\/li>\r\n<\/ul>\r\n<h3><span style=\"font-weight: 400\">Types of Inflation Based on Causes<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">Inflation can stem from various economic factors, including increased demand, higher production costs, structural issues, or supply constraints in specific sectors. Understanding these causes helps in crafting effective inflation control strategies.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Demand-Pull Inflation: <\/b><span style=\"font-weight: 400\">Demand-pull inflation occurs when an increase in the supply of money and credit causes overall demand for goods and services to rise faster than the economy's production capacity. This increases demand, which leads to price increases.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Cost-Push Inflation: <\/b><span style=\"font-weight: 400\">Cost-push inflation is caused by an increase in prices for inputs used in the production process. When more money and credit are channelled into commodity or other asset markets, prices for all types of intermediate goods rise. This is especially evident when a negative economic shock disrupts the supply of key commodities.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Built-in Inflation:<\/b><span style=\"font-weight: 400\"> Built-in inflation is associated with adaptive expectations, which hold that current inflation rates will persist in the future. People may expect the price of goods and services to continue rising at a similar rate in the future.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Structural Inflation: <\/b><span style=\"font-weight: 400\">Structural inflation occurs due to economic issues such as rigid supply chains or monopolistic market structures, leading to periodic price hikes in specific sectors.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Protein Inflation: <\/b><span style=\"font-weight: 400\">Specifically related to the food sector, protein inflation refers to price increases in protein-rich food products like pulses, eggs, and meat, often due to demand shifts or supply constraints.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation Causes<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Inflation arises from demand-pull factors, cost-push factors, supply shocks, increased money supply, wage-price spirals, inflation expectations, and certain fiscal policies. These elements collectively drive price increases, impacting purchasing power.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Demand-Pull Factors:<\/b><span style=\"font-weight: 400\"> When demand for goods and services exceeds supply, prices increase. This often happens when there is an influx of cash or credit in the economy, stimulating purchasing beyond the economy\u2019s capacity.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Cost-Push Factors: <\/b><span style=\"font-weight: 400\">Rising production costs can also cause inflation. When the costs of inputs like raw materials and labour increase, companies pass these costs on to consumers through higher prices.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Supply Shocks: <\/b><span style=\"font-weight: 400\">Sudden disruptions to supply, such as natural disasters, conflicts, or pandemics, can significantly reduce the availability of critical goods.\u00a0<\/span>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">For example, supply chain issues during <\/span><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/covid-19\/\" target=\"_blank\"><span style=\"font-weight: 400\">COVID-19<\/span><\/a><span style=\"font-weight: 400\"> led to price spikes across sectors.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n\t<li style=\"font-weight: 400\"><b>Increased Money Supply: <\/b><span style=\"font-weight: 400\">A significant increase in the money supply can drive inflation, as more cash circulating in the economy fuels higher demand. With too much money chasing too few goods, prices tend to rise.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Wage-Price Spirals: <\/b><span style=\"font-weight: 400\">When workers demand higher wages to cope with rising prices, businesses often raise prices to cover these increased labour costs. This cycle, known as the wage-price spiral, can fuel sustained inflation.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Inflation Expectations: <\/b><span style=\"font-weight: 400\">When people expect inflation to persist, they may demand higher wages and buy goods now to avoid future price increases, reinforcing inflation. Central banks aim to keep these expectations stable to control inflation.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Fiscal Policies:<\/b><span style=\"font-weight: 400\"> Government policies like tax cuts or increased public spending can raise overall demand, leading to inflation if the economy is already operating at full capacity and supply cannot keep pace.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation Measurement<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Inflation is measured using indices that track price changes in a basket of goods and services over time. A price index is a statistical measure that reflects changes in this average price level relative to a base year. In India, inflation is primarily tracked using two main price indices: the Wholesale Price Index (WPI) and the Consumer Price Index (CPI). Globally, another widely used measure of inflation is the GDP Deflator.<\/span><\/p>\r\n<h3><span style=\"font-weight: 400\">Wholesale Price Index (WPI)<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">The <\/span><span style=\"font-weight: 400\">Wholesale Price Index (WPI)<\/span><span style=\"font-weight: 400\"> measures and tracks price changes in the wholesale market, focusing on goods traded between companies. It excludes services and is calculated monthly, representing a broad view of inflation at the wholesale level. In India, it is published by the Office of Economic Adviser, Department for Promotion of Industry and Internal Trade, with base year 2011-12.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The base year of the Wholesale Price Index has been revised from 2011\u201312 to 2022\u201323.<\/span><\/li>\r\n<\/ul>\r\n<h3><span style=\"font-weight: 400\">Consumer Price Index (CPI)<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">The <\/span><span style=\"font-weight: 400\">Consumer Price Index (CPI)<\/span><span style=\"font-weight: 400\"> tracks changes in the cost of a typical basket of goods and services over time, reflecting the overall shift in consumer prices. It is a key inflation measure monitored closely by policymakers, financial markets, businesses, and consumers alike. Unlike WPI, it includes services. The National Statistical Office of the Ministry of Statistics and Programme Implementation publishes it.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">From 2026, the consumption basket and weights for both rural and urban households are updated, and the CPI base year is changed to 2024.<\/span><\/li>\r\n<\/ul>\r\n<h3><span style=\"font-weight: 400\">Producer Price Index (PPI)<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">The Producer Price Index (PPI) measures price changes from the perspective of producers, capturing input cost changes across manufacturing and production sectors. While PPI does not account for consumer prices, it provides insight into cost pressures that may eventually impact retail prices.<\/span><\/p>\r\n<h3><span style=\"font-weight: 400\">GDP Deflator<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">The GDP Deflator measures price level changes across the entire economy, covering both <a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/gross-domestic-product-gdp\/\" target=\"_blank\">goods and services products (GDP)<\/a> domestically. It reflects the overall inflation rate by comparing the ratio of nominal GDP to real GDP. Unlike the Consumer Price Index (CPI), the GDP deflator allows for comparisons across multiple periods without relying on a fixed base year or a set basket of goods.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The GDP Deflator value is calculated using the formula: GDP deflator = (Nominal GDP \/ Real GDP) * 100.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation Impacts<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Inflation impacts various aspects of the economy, from reducing purchasing power and increasing interest rates to widening income inequality and affecting investment returns. It also hampers export competitiveness and raises business costs, complicating economic planning.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Reduced Purchasing Power: <\/b><span style=\"font-weight: 400\">Inflation erodes the purchasing power of money, meaning consumers can buy fewer goods and services with the same income, ultimately affecting their quality of life and standard of living.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Increased Interest Rates: <\/b><span style=\"font-weight: 400\">To control inflation, central banks often raise interest rates, making borrowing more expensive for individuals and businesses and slowing economic growth and investment.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Income Inequality: <\/b><span style=\"font-weight: 400\">Inflation impacts income groups unevenly. Lower-income households feel the pinch more as a larger portion of their income goes toward essentials, widening the gap between socioeconomic classes.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Investment Returns: <\/b><span style=\"font-weight: 400\">Inflation diminishes real returns on investments, especially fixed-income assets, as the purchasing power of returns declines, potentially discouraging savings and long-term investment.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Export Competitiveness: <\/b><span style=\"font-weight: 400\">Rising domestic prices make exports less competitive internationally, as foreign buyers may seek cheaper alternatives elsewhere, potentially harming industries that rely on exports for revenue.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Business Costs and Planning:<\/b><span style=\"font-weight: 400\"> Inflation raises operational costs for businesses, especially in materials and labour, leading to challenges in pricing and long-term planning as businesses struggle to maintain profit margins.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation Control Measures<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Measures to control inflation include adjusting interest rates, reducing government spending, boosting supply efficiency, and employing exchange rate policies, price controls, and subsidies to stabilise prices and maintain economic stability.<\/span><\/p>\r\n<ul>\r\n\t<li><b>Monetary Policy Measures: <\/b><span style=\"font-weight: 400\">The <\/span><span style=\"font-weight: 400\">Monetary Policy Committee<\/span><span style=\"font-weight: 400\"> is entrusted with fixing the benchmark policy rate required to contain inflation within the specified target level.<\/span><\/li>\r\n\t<li><span style=\"font-weight: 400\">As per the revised monetary policy framework, the Government has fixed the inflation target of 4% with a tolerance level of +\/\u20142 per cent.\u00a0\u00a0<\/span><\/li>\r\n\t<li><span style=\"font-weight: 400\">RBI may also use qualitative control methods, such as raising margins on loans for commodities that traders tend to speculate on and hoard.<\/span><\/li>\r\n\t<li><span style=\"font-weight: 400\">The Reserve Bank of India may also resort to other operations, such as Open Market Operations, to remove liquidity from the market by selling government securities and bonds.<\/span><\/li>\r\n\t<li><b>Fiscal Measures: <\/b><span style=\"font-weight: 400\">The government can take two routes to bring down prices through this method. It can cut down its spending on various schemes, projects, etc. It can increase taxes (either directly or indirectly).<\/span><\/li>\r\n\t<li><b>Supply-Side Policies: <\/b><span style=\"font-weight: 400\">These aim to increase production efficiency. By improving infrastructure, encouraging innovation, and removing regulatory barriers, supply-side policies help reduce production costs, thereby controlling cost-push inflation.<\/span><\/li>\r\n\t<li><b>Exchange Rate Policy: <\/b><span style=\"font-weight: 400\">A strong currency can reduce import prices, making goods and services cheaper. Governments may intervene in the <\/span><span style=\"font-weight: 400\">foreign exchange<\/span><span style=\"font-weight: 400\"> market to stabilise the currency, indirectly controlling inflation through lower import costs.<\/span><\/li>\r\n\t<li><b>Price Controls and Subsidies: <\/b><span style=\"font-weight: 400\">Temporary price controls on essential goods can help limit inflation. Governments may also provide subsidies to reduce the cost of essential products like food and fuel, stabilising prices in the short term.<\/span><\/li>\r\n\t<li><b>Targeted Interventions: <\/b><span style=\"font-weight: 400\">In cases of specific inflationary pressures, such as food inflation, governments may release buffer stocks or modify import policies to ensure adequate supply, addressing price rises in critical sectors.<\/span><\/li>\r\n<\/ul>\r\n<h2><span style=\"font-weight: 400\">Inflation UPSC PYQs<\/span><\/h2>\r\n<p><b>Q1: <\/b><span style=\"font-weight: 400\">What are the causes of persistent high food inflation in India?
