What is Inflation? Definition, Rate, Causes, Calculation Method, Good Level and Bad Level

What is Inflation?

Inflation is the overall hike in the level of prices of goods and services in an economy over a period of time. Means purchasing power erosion of money and price increase in goods & services which being used in an economy or households.

The most commonly used measure of inflation is the Consumer Price Index (CPI), which tracks changes in the prices of a basket of goods and services typically consumed by households.

What is Inflation Rate?

The inflation rate can be referred to the percentage change in the general price level of goods and services in an economy over a period of time, usually a year. It is commonly measured by an inflation index, such as the Consumer Price Index (CPI), which tracks the prices of a basket of goods and services consumed by households.

For example, if the CPI in a given year is 110, it means that the average price of goods and services has increased by 10% compared to the previous year. The inflation rate in this case would be 10%.

Inflation rates can vary widely across different countries and time periods, depending on a variety of factors such as changes in supply and demand, shifts in government policies, and external shocks such as changes in global commodity prices.

What Causes Inflation?

Inflation can be caused by various factors, and followings are some of them:

  1. Increase in demand: When demand for goods and services increases, and the supply is unable to keep up, prices rise. This is known as demand-pull inflation.
  2. Increase in production costs: An increase in the cost of raw materials, labour, or other production inputs can lead to higher prices for the finished goods and services.
  3. Decrease in supply: If the supply of goods and services decreases, while demand remains constant or increases, it can lead to scarcity and higher prices. This is known as cost-push inflation.
  4. Increase in money supply: When the central bank increases the money supply, it can lead to an increase in demand for goods and services, which can cause inflation.
  5. Changes in exchange rates: A decrease in the value of the domestic currency can cause imported goods to become more expensive, leading to higher prices.
  6. Government policies: Government policies such as taxes, subsidies, and regulations can affect the supply and demand for goods and services, which can in turn impact prices.

What Inflation may Cause to an Economy?

Inflation can have various effects on an economy and its participants, like:

  1. Reduced purchasing power: Inflation can erode the value of money, reducing the purchasing power of individuals and businesses. This can make it more difficult for people to afford the same goods and services, leading to a decrease in their standard of living.
  2. Increase in interest rates: High inflation can lead to an increase in interest rates, as central banks aim to control inflation by reducing the money supply. Higher interest rates can discourage borrowing and investment, and slow down economic growth.
  3. Uncertainty: High and volatile inflation rates can create uncertainty for businesses and consumers, making it difficult to plan for the future and make long-term investments.
  4. Redistribution of income: Inflation can result in a redistribution of income from savers to borrowers. This is because borrowers can repay their debts with money that has less purchasing power than when they borrowed it, while savers see the value of their savings decrease.
  5. Increase in costs: Inflation can lead to an increase in the cost of production, which can reduce profits and lead to higher prices for consumers. This can create a vicious cycle of rising costs and prices.
  6. Decline in exports: If inflation causes a country’s currency to depreciate, its exports can become more expensive for foreign buyers, leading to a decline in demand and a decrease in economic growth.

Inflation in Stock Market:

Inflation in the stock market is the impact of rising prices on the value of stocks and the overall performance of the stock market. When inflation increases, it can affect the economy in various ways, which can, in turn, affect the stock market.

For example, rising inflation may lead to higher interest rates, which can increase the cost of borrowing for companies and reduce the profitability of their operations. In this scenario, companies may find it harder to raise capital, leading to a decline in stock prices. On the other hand, certain sectors such as commodities, real estate, and infrastructure may benefit from inflation, leading to higher stock prices.

Additionally, investors may become concerned about the future direction of inflation, leading them to adjust their investment strategies. For example, they may sell stocks and move their money into bonds or other investments that offer a hedge against inflation.

How to Control Inflation?

There are several ways to control inflation which can be initiated by government authority, such as:

  1. Monetary policy: Central banks can use monetary policy tools, such as adjusting interest rates or the money supply, to control inflation. Higher interest rates can reduce demand for goods and services and lower inflation, while lower interest rates can stimulate demand and increase inflation. Central banks can also adjust the money supply to control inflation, such as by buying or selling government bonds.
  2. Fiscal policy: Governments can use fiscal policy tools, such as changing tax rates or government spending, to influence aggregate demand and control inflation. For example, reducing government spending or increasing taxes can reduce demand and lower inflation, while increasing government spending or cutting taxes can stimulate demand and increase inflation.
  3. Supply-side policies: Policies that aim to increase the supply of goods and services can help to lower inflation. For example, removing barriers to entry for businesses, improving infrastructure, and investing in education and training can help to increase productivity and lower costs.
  4. Wage and price controls: Governments can also impose wage and price controls to limit the increase in wages and prices. However, these policies are often controversial and can lead to unintended consequences, such as shortages, reduced quality, and decreased investment.
  5. Exchange rate policy: In some cases, governments can control inflation by adjusting the exchange rate of their currency. Depreciating the currency can make imports more expensive, reducing demand and lowering inflation, while appreciating the currency can have the opposite effect.

Inflation Calculation Method:

Inflation is calculated using a price index, which measures the average change in prices of a basket of goods and services over time. The most commonly used price index is the Consumer Price Index (CPI), which measures the change in the cost of a fixed basket of goods and services consumed by households. Here are the basic steps for calculating inflation using the CPI:

  1. Choose a base year: The base year is the starting point for the calculation of inflation. In the US, the base year for CPI calculation is 1982-1984, and its value is set to 100.
  2. Determine the basket of goods: The basket of goods and services should represent the average consumption patterns of households in the economy. The composition of the basket may change over time to reflect changes in consumer preferences or new goods and services.
  3. Collect price data: Collect the prices of each item in the basket for the current year and the base year. The prices should be collected from a representative sample of outlets, such as supermarkets or department stores.
  4. Calculate the CPI: The CPI is calculated by dividing the cost of the basket of goods and services in the current year by the cost of the basket in the base year and multiplying the result by 100.
  5. Calculate inflation rate: The inflation rate is the percentage change in the CPI over a period of time. It can be calculated by subtracting the CPI of the previous year from the CPI of the current year, dividing the result by the CPI of the previous year, and multiplying by 100.

Inflation rate = (CPI current year – CPI previous year) / CPI previous year x 100

Good Inflation vs Bad Inflation:

Inflation can be categorized into “good inflation” and “bad inflation” based on the underlying causes and their impact on the economy.

Good inflation is a moderate and sustainable increase in prices, typically driven by increased demand for goods and services, as well as investment and growth in the economy. This type of inflation can stimulate economic activity, encourage investment and spending, and support job creation. Central banks often aim for a low and stable level of inflation, typically around 2%, to achieve these benefits.

On the other hand, bad inflation is high and unstable inflation rates that can have detrimental effects on the economy. This type of inflation is often driven by factors such as a rapid increase in the money supply, a decrease in the supply of goods and services, or external factors such as wars or natural disasters. Bad inflation can cause a decrease in the value of money, erode the purchasing power of individuals and businesses, create uncertainty, and lead to a decline in economic growth.

High and volatile inflation can also lead to a variety of negative economic and social consequences, such as increased unemployment, reduced investment, and social unrest.

Overall, the impact of inflation on the economy depends on its severity, duration, and the response of policymakers and market participants. Moderate and sustainable inflation can have positive effects on the economy, while high and unstable inflation can have negative consequences.
