Reading Time: 1 minutes

Inflation, like an invisible force, permeates the core of every economy, shaping financial landscapes and impacting daily lives. From the price tags on grocery shelves to the intricacies of interest rates, inflation’s influence is pervasive and profound. 

Understanding this economic phenomenon is paramount, as it not only affects personal finances but also guides central bank policies and shapes investment strategies. In this blog, we will delve into the depths of what an increase in the prices of goods and services is, unraveling its causes, effects, and strategies employed to manage its impact. In this article, we will explore what is inflation and its causes.

What is Inflation?

Inflation is a fundamental economic concept characterized by a persistent increase in the general price levels of goods and services within an economy. Put simply, it means that over time, the purchasing power of money diminishes as the cost of living rises. This can impact consumers, businesses, and the overall economic landscape.

What is Inflation Rate?

The inflation rate is a metric used to gauge how fast the general prices of goods and services in an economy are rising over a defined period, often a year. It’s a vital economic measure indicating the pace of price increases. A higher rate signifies a more rapid price surge, which can erode the purchasing power of the currency. 

Conversely, a lower rate suggests a more gradual increase in prices. Monetary authorities and policymakers keep a watchful eye on this rate to maintain price stability. They may modify monetary policies to manage the increase in the prices of goods and services and its impacts on the economy.

What is the Inflation Rate in India?

The inflation rate in India pertains to the pace at which the general prices of goods and services in the country increase over a defined time frame, usually a year. This figure is a vital economic gauge illustrating the extent to which the purchasing power of the Indian Rupee is decreasing due to escalating prices. 

The computation of this rate involves the utilization of different indices, including the Consumer Price Index (CPI) and the Wholesale Price Index (WPI), both of which track alterations in the costs of goods and services frequently utilized by households and businesses. 

The Reserve Bank of India (RBI) diligently monitors this rate and employs monetary policy mechanisms to maintain it within a targeted range. This is crucial because excessive increase in the prices of goods and services can yield adverse repercussions on the economy, including diminished consumer spending capacity and instability in financial markets.

Note: As of August 10, 2023, the current inflation rate in India is 4.81%.

What are the Measurement Methods of Inflation?

Inflation is quantified using indices such as the Consumer Price Index (CPI) and the Producer Price Index (PPI). The CPI evaluates the average price changes paid by consumers for a predetermined basket of goods and services, thus reflecting the changes in the cost of living. The PPI, on the other hand, gauges the average price fluctuations received by producers for their goods.

How to Calculate Inflation?

To calculate the inflation rate, use the formula: 

(Ending Value – Starting Value)/Starting Value x 100.

The starting value (A) is the consumer price index from a specific past period, while the ending value (B) is the current index for the same item. Subtract these values to find the difference, representing the increase in the consumer price index. Divide this result by the starting value and multiply by 100 to get this rate.

How Does Inflation Work?

Inflation is the persistent increase in prices for goods and services over time, eroding your purchasing power—the ability to buy with a single unit of currency. It’s not just about a specific item costing more; it involves widespread and ongoing price hikes across various regular expenses like groceries, gas, utilities, and travel.

The root cause of an increase in the prices of goods and services often lies in the imbalance between supply and demand, key economic forces. Supply, determined by businesses, denotes the production and sale of goods or services. On the other hand, demand, driven by consumers, signifies the quantity of a good or service purchased at a given price. When demand surpasses supply, an increase in the prices of goods and services is likely to occur.

What are the Main Causes of Inflation?

Inflation is caused by a variety of causes. The causes are as follows:

Demand-Pull Inflation

This occurs when consumer demand surpasses the supply of goods and services within an economy. This leads to scarcity, which subsequently drives up prices. Typically observed during periods of economic growth or increased government spending, this type is fueled by greater consumer purchasing power, resulting in heightened demand. It is the main cause of inflation. 

Cost-Push Inflation

This arises from escalating production costs that prompt producers to raise prices on their offerings. This can be due to increased expenses for raw materials, wages, or other inputs. Such cost increments are often transferred to consumers in the form of higher prices for goods and services. External factors, such as supply chain disruptions or geopolitical events, can also contribute to this type of inflation.

Built-In Inflation

This is also known as wage-price inflation, unfolds when an economy enters a self-perpetuating cycle of wage hikes followed by corresponding price increases. As workers demand higher wages to counter rising living expenses, businesses react by raising prices to accommodate greater labour costs. This sequence can initiate a loop of continuous wage demands and price escalations, fostering a cycle of inflation.

Types of Price Index 

Here are the various types of prices indices:

Consumer Price Index (CPI)

The U.S. Bureau of Labor Statistics calculates the CPI monthly, monitoring changes in prices consumers pay for various goods and services. Using a “basket of goods” method, it tracks eight key categories: food and beverages, housing, apparel, transportation, education, communication, recreation, medical care, and other goods and services.

The CPI is widely considered the primary gauge of inflation in the United States. It holds particular significance as the basis for determining cost of living adjustments for Social Security payments and many corporate annual raises. Additionally, it influences the rates on certain inflation-protected securities, such as Treasury Inflation-Protected Securities (TIPS).

Producer Price Index (PPI)

Also published by the Bureau of Labor Statistics, the PPI monitors monthly changes in the prices companies receive for their goods and services. Factors like increased tariffs, rising oil and gas prices for transportation, and external challenges (e.g., pandemics or environmental events) can contribute to cost fluctuations.

The PPI plays a crucial role in business contracts, particularly in long-term agreements with suppliers. It allows businesses to automatically adjust payment rates for raw goods and services over time, preventing suppliers from being locked into disadvantageous long-term contracts.

Personal Consumption Expenditures Price Index (PCE)

Published by the Bureau of Economic Analysis, the PCE tracks consumer spending on goods and services, encompassing a broader range than the CPI, including healthcare. It dynamically updates its basket of goods based on monthly consumer spending rather than relying on a fixed set of items.

The PCE holds special importance as the Federal Reserve’s preferred inflation measure for making monetary decisions.

Impact of Inflation on the Economy

A situation like inflation can have a significant impact on the economy. Let’s explore how:

  • Impact on Purchasing Power: It can substantially erode the purchasing power of a currency. When prices rise, each unit of currency buys fewer goods and services. This means that consumers may need to allocate more of their income to cover basic necessities, leaving less room for discretionary spending. 
  • Income Redistribution Effects: It effects of an increase in the prices of goods and services are not uniformly distributed among different socioeconomic groups. Those on fixed incomes, such as retirees, may find it challenging to keep up with rising prices, potentially diminishing their purchasing power. On the other hand, individuals with assets that tend to appreciate during an increase in the prices of goods and services, like real estate or stocks, might experience an increase in their net worth. This can lead to income redistribution, favouring those with certain types of assets over others.
  • Effects on Savings and Investments: It can significantly impact savings and investments. If the interest rates offered on savings accounts or fixed-income investments are lower than the inflation rate, the real value of these savings could decrease over time. Investors seeking to preserve their wealth might need to explore investment options that outpace an increase in the prices of goods and services in economy. On the positive side, certain assets, like stocks or real estate, can serve as hedges against inflation, potentially providing returns that surpass rising prices.

How Does Inflation Affect Interest Rates?

Inflation and interest rates share a symbiotic relationship that profoundly influences the economic landscape. As inflation rises, central banks often respond by adjusting interest rates. This adjustment is a strategic move to control the pace of economic growth and maintain price stability.

When the prices of goods and services is on the ascent, central banks may opt to raise interest rates. This serves a dual purpose: first, it makes borrowing more expensive, which can help cool down spending and investment, thus curbing inflation. Second, higher interest rates make saving more attractive, encouraging individuals to save rather than spend. This dynamic helps stabilize prices by reducing overall demand.

Conversely, during periods of deflationary pressures, central banks may lower interest rates. This aims to stimulate economic activity by making borrowing more affordable, fostering increased spending and investment.

Types of Inflation in Economics

Some of the different types of inflation are as follows:

  • Mild/Moderate Inflation: This refers to a controlled and gradual rise in the general price level of goods and services within an economy. This kind of inflation, often considered normal, is managed by central banks to ensure stability and encourage economic growth. Moderate inflation is also known as creeping inflation. 
  • Hyperinflation: Hyperinflation is an extreme form of increase in the prices of goods and services characterized by incredibly rapid and uncontrollable price increases. In such situations, prices can double or even quadruple within a short span, leading to the erosion of purchasing power and economic instability. 
  • Deflation: Deflation is a sustained decrease in the general price level of goods and services. Although it might seem advantageous to consumers, deflation and the effects of deflation can initiate a negative cycle of reduced spending, decreased business profits, and increased unemployment.
  • Disinflation: Disinflation refers to a slowing down of this rate. Prices are still rising but at a lower rate. Disinflation can indicate a healthier economy, but its consequences depend on the overall economic context.

What are the Factors that Influence Inflation?

Some factors that influence Inflation are:

Monetary Policy

Monetary policy plays a pivotal role in influencing inflation. Central banks regulate the money supply and interest rates to control an increase in the prices of goods and services. When a central bank increases the money supply excessively or keeps interest rates very low, it can fuel demand for goods and services. This demand-driven inflation occurs as consumers and businesses spend more money in the economy. Conversely, tightening the money supply or raising interest rates can help combat this by reducing consumer spending.

Fiscal Policy

Fiscal policy, controlled by governments, involves taxation and government spending. When governments increase spending or reduce taxes, it boosts consumer purchasing power and overall demand, often leading to demand-pull inflation. On the other hand, policies that aim to curb spending or raise taxes can help mitigate this.

Supply Shocks

Supply shocks are sudden disruptions in the availability of goods or services. These can be caused by factors such as natural disasters, geopolitical events, or supply chain interruptions. Supply shocks can lead to cost-push inflation, as the reduced supply of certain goods can drive their prices upward. For instance, an oil supply disruption can result in higher energy prices, which can affect prices throughout the economy.

Expectations of Future Prices

People’s expectations about future prices can impact current inflation. If consumers anticipate rising prices, they may increase their spending to avoid paying more in the future, creating demand-pull inflation. Businesses might also raise their prices in anticipation of higher costs, contributing to cost-push inflation. Central banks often consider managing expectations as a part of their inflation-fighting strategy.

What is the Role of the Central Bank in Managing Inflation?

Central banks play a pivotal role in managing inflation. They implement monetary policies to control the money supply and interest rates. By influencing borrowing costs and money circulation, central banks aim to stabilize prices and ensure economic growth. Let’s examine further:

Interest Rate Adjustments

Central banks often use interest rate adjustments to manage inflation. When inflation rises, they may increase interest rates to discourage borrowing and spending, which can help rein in demand and lower prices. Conversely, during economic slowdowns, lower interest rates can encourage borrowing and spending to stimulate demand.

Open Market Operations

Open market operations involve central banks buying or selling government securities. Buying injects money into the economy, boosting demand and potentially increasing prices of goods and services. Selling removes money from circulation, reducing need and helping lower inflation.

Exchange Rate Policies

Exchange rate policies can impact inflation, especially in economies that heavily rely on imports. A stronger currency can lower import costs, contributing to lower inflation. Conversely, a weaker currency can increase import costs, potentially leading to higher inflation. Central banks may intervene in foreign exchange markets to influence exchange rates and manage the increase in the prices of goods and services accordingly.

How to Deal with Inflation?

Here are some effective strategies to combat inflation:

  • Strategies for Individuals: Individuals can employ strategies to navigate inflation’s impact. Investing in assets historically resistant to this, like stocks or real estate, can preserve purchasing power. Diversifying across assets and regions mitigates risk. Budgeting and reducing discretionary spending help counter rising costs.
  • Impact on Businesses: It poses challenges for businesses, elevating production expenses, including labor and materials. To manage, they may pass costs to consumers, affecting demand. Companies could also focus on efficiency and cost-cutting measures to sustain profits.
  • Government Policies and Interventions: Governments can address this through policies. Monetary measures (interest rates) manage money supply, fiscal policies (taxation, spending) handle demand, and supply-side actions enhance production efficiency. Price controls and social support aid vulnerable groups.

Historical Instances of Inflation in India

  • The Great Inflation (1970s): The 1970s marked a significant period of an increase in the prices of goods and services in India triggered by factors such as food shortages, supply disruptions, and global oil price shocks. This led to a considerable rise in annual inflation rate in India, causing economic instability.
  • Post-Liberalization Inflation (1990s): Following economic liberalization in the 1990s, the increase in the prices of goods and services continued to be a concern due to structural adjustments and heightened consumer demand. The opening up of the economy introduced new dynamics in price movements.
  • Surge in Food Inflation (2000s): Around 2007-2008, India encountered a notable surge in food inflation mainly attributed to supply limitations and global escalations in food prices. This had direct implications on household budgets, prompting the need for policy interventions.
  • Recent Inflation Trends (2020s): In the current decade, an increase in the prices of goods and services witnessed fluctuations due to various reasons, including disruptions in supply chains due to the COVID-19 pandemic. These temporary imbalances contributed to price volatility.

Inflation’s Role in the Economy

Inflation is a complex economic phenomenon with significant implications for the overall health of an economy. Let’s explore its role more deeply:

Importance of Controlled Inflation

Maintaining inflation at moderate levels is crucial for a thriving economy. It fosters consumer spending and business investment by discouraging hoarding of money. Additionally, controlled inflation encourages borrowing as interest rates usually exceed inflation rates, ensuring lenders a profit.

Relationship between Inflation and Economic Growth

The connection between inflation and deflation economic growth is delicate. While moderate inflation often signals a growing economy, excessive increase in the prices of goods and services can be harmful. Steep inflation erodes purchasing power, increasing costs for goods and services. This can lead to reduced consumer spending and economic slowdown. 

Central banks strive to balance this equation by aiming for optimal inflation rate in India that stimulate growth without causing economic strain. This understanding is pivotal for policymakers and investors, in shaping effective economic policies and investment strategies.

To Wrap It Up…

Inflation is a fundamental economic force that influences various aspects of our lives. It’s not merely about rising prices but a complex interplay of factors affecting economies, individuals, businesses, and governments. By understanding its causes, effects, and management strategies, you gain insights into how economies operate and evolve.


1. What is inflation and example?

It is the sustained increase in the general price level of goods and services in an economy over a period of time. This means that, on average, the cost of living is rising. For example, if the price of a loaf of bread goes from $2 to $2.50 over a year, that’s a sign of this phenomenon.

2. What are the 3 main causes of inflation?

The three main causes of boom are demand exceeding supply (demand-pull), increased production costs (cost-push), and wage-price spirals (built-in).

3. What are 3 types of inflation?

The three types of inflation are mild/moderate, hyperinflation (rapid and extreme), and deflation/disinflation (price slowdown).

4. What is Retail Inflation?

Retail inflation pertains to the surge in the average cost of goods and services commonly bought by individuals for their daily needs. 

5. What is the highest inflation rate in India for last 10 years?

Tthe average inflation rate in India for the last 10 years is 6.01%

6. What is purchasing power risk?

Inflation risk, also known as purchasing power risk, arises when it erodes the actual value of investment cash flows.

7. Who benefits from inflation and what are its effects?

Inflation can be advantageous for those grappling with significant debts, offering relief in repayment. Conversely, individuals with fixed incomes and cash reserves may experience negative impacts due to this.
