Inflation – Types, Causes & Control Measures
🟠 Topic 48: Inflation – Types, Causes & Control Measures
📌 Introduction
Inflation refers to the persistent rise in the general price level of goods and services over time. While moderate inflation is a sign of growing demand in a healthy economy, excessive inflation reduces purchasing power, increases cost of living, and hurts fixed income groups. Controlling inflation is a key objective of India’s monetary and fiscal policy frameworks.
🔹 What is Inflation?
📖 Definition
Inflation is the rate at which the general level of prices for goods and services rises, and consequently, the purchasing power of currency falls.
📊 Inflation Measurement in India
| Index | Coverage |
|---|---|
| Consumer Price Index (CPI) | Retail inflation (goods & services for consumers) |
| Wholesale Price Index (WPI) | Wholesale inflation (goods traded in bulk) |
| GDP Deflator | Broader measure including all economic output |
Inflation Target (Under RBI Act, 2016)
| Parameter | Target |
|---|---|
| Inflation Target (CPI) | 4% |
| Upper Limit | 6% |
| Lower Limit | 2% |
🔹 Types of Inflation
1️⃣ Demand-Pull Inflation
- Caused by excess demand in the economy.
- Aggregate demand exceeds aggregate supply.
- Common in booming economies.
Example: Increase in demand for consumer durables due to rising incomes.
2️⃣ Cost-Push Inflation
- Caused by a rise in production costs (wages, raw materials, fuel).
- Producers pass on higher costs to consumers.
Example: Sharp increase in crude oil prices raising transportation and production costs.
3️⃣ Structural Inflation
- Caused by rigidities in supply chains, particularly in developing economies.
- Includes inefficiencies in agriculture, infrastructure, and logistics.
Example: Supply bottlenecks in essential commodities.
4️⃣ Built-in Inflation (Wage-Price Spiral)
- Workers demand higher wages due to rising prices.
- Higher wages lead to higher production costs, further increasing prices.
Example: Post-pandemic wage hikes in the service sector.
5️⃣ Imported Inflation
- Caused by an increase in import prices, especially of essential commodities.
- Affects countries dependent on imports for energy, food, and technology.
Example: Rising prices of crude oil, edible oil, fertilizers affecting India.
6️⃣ Hyperinflation
- Extremely rapid, out-of-control price increases.
- Leads to currency collapse.
Example: Zimbabwe (2008) where prices doubled every few hours.
7️⃣ Stagflation
- Combination of stagnant economic growth, high unemployment, and high inflation.
- Difficult to manage using conventional policies.
Example: 1970s oil crisis, global stagflation.
🔹 Causes of Inflation
1️⃣ Demand-Side Factors
| Cause | Example |
|---|---|
| Higher disposable income | Wage hikes, tax cuts |
| Credit expansion | Easy loans, low-interest rates |
| Government spending | Higher public expenditure |
| Export boom | Global demand for Indian goods |
2️⃣ Supply-Side Factors
| Cause | Example |
|---|---|
| Costlier inputs | Oil price hikes |
| Supply disruptions | Natural disasters, pandemics |
| Labour strikes | Disruption in production chains |
| Logistics inefficiencies | Transport bottlenecks |
3️⃣ Structural Factors
| Cause | Example |
|---|---|
| Agricultural dependency | Low crop productivity |
| Poor infrastructure | High logistics costs |
| Market imperfections | Cartelisation, hoarding |
🔹 Impact of Inflation
1️⃣ On Consumers
- Erodes purchasing power.
- Hurts fixed income groups.
2️⃣ On Businesses
- Higher input costs.
- Planning becomes difficult.
3️⃣ On Savings & Investments
- Reduces real returns on savings.
- Encourages investment in real assets like gold.
4️⃣ On Economy
- Encourages speculative investments.
- Widening wealth inequality.
- Can trigger social unrest if unchecked.
🔹 Inflation Control Measures
1️⃣ Monetary Measures (RBI)
| Tool | Explanation |
|---|---|
| Repo Rate Hike | Makes borrowing costlier, reduces demand |
| CRR & SLR Increase | Reduces bank lending capacity |
| Open Market Operations (OMO) | Sells government bonds to absorb liquidity |
Example
In 2022-23, RBI raised repo rates to curb post-pandemic demand-driven inflation.
2️⃣ Fiscal Measures (Government)
| Tool | Explanation |
|---|---|
| Reducing Taxes | Lower excise on fuel to reduce transport costs |
| Rationalising Subsidies | Efficient subsidy targeting to avoid excess demand |
| Supply-Side Boost | Investment in agriculture, infrastructure, and energy production |
Example
- Reduction in fuel taxes in 2022 to control inflation.
- Free grain distribution under PM Garib Kalyan Anna Yojana to check food inflation.
3️⃣ Administrative & Regulatory Measures
| Tool | Explanation |
|---|---|
| Stock Limits | Control hoarding of essential goods |
| Import Policy Tweaks | Reduce import duties to lower prices |
| Price Controls | Regulate prices of essential commodities (not always effective) |
Example
Stock limits on pulses & edible oils during price spikes.
🔹 Inflation Index in India – CPI vs WPI
| Factor | CPI | WPI |
|---|---|---|
| Full Form | Consumer Price Index | Wholesale Price Index |
| Coverage | Goods & services | Goods only |
| Base | Retail market prices | Wholesale market prices |
| Weightage | Higher weight for food & services | Higher weight for manufactured goods |
| Relevance | Tracks cost of living | Tracks producer prices |
✅ CPI is the primary inflation gauge for monetary policy under Inflation Targeting Framework.
📊 Inflation Trend (2023)
| Indicator | Value |
|---|---|
| CPI Inflation (Average) | ~5.5% |
| WPI Inflation (Average) | ~1.3% |
| Core Inflation (excl. food & fuel) | ~4.9% |
🔹 Case Study – Food Inflation Management
- India experienced double-digit food inflation in 2022 due to: ✔️ Heatwaves impacting wheat output. ✔️ Global edible oil shortages (Ukraine war). ✔️ Supply chain disruptions post-COVID.
Measures Taken
✔️ Export curbs on wheat & rice.
✔️ Stock limits on pulses.
✔️ Import duty cuts on edible oils.
✔️ Boosting supply via open market sales by FCI.
