What is Inflation?

Inflation is the rate at which the general level of prices for goods and services rises, and consequently, the purchasing power of money falls.

If inflation is 5% per year, then something that costs ₹100 today will cost ₹105 a year later. The higher the inflation rate, the faster your money loses value.

Key Features of Inflation

• It is expressed as a percentage.

• It impacts everyday expenses like food, fuel, and housing.

• It can be temporary or long-term.

• It is influenced by supply, demand, government policy, and global markets.

One need to understand “time value of money” as money loses its value over time, investing becomes important. Investing make sure a sustainable economic growth of a country and overall.

Therefore as an normal person or an investor you should know the (TMV) “time value of money” the value of money does not remain the same across time.

Meaning, the value of Rs.10000 today is not really Rs.10000 3 years from now. Oppositely, the value of Rs.10000 3 years from now is not really Rs.10000 as of today.

Whenever there is motion of time, there is an element of opportunity. Money has to be accounted or adjusted for that opportunity as in case inflation is that element.

Due to inflation, the value of money decreases over time. For example if you have kept Rs. 1,00,000 with you as idle for 5 years instead of investing, assuming an inflation rate of 7% per annum the value of your money will be reduced to Rs.71,299 in percentage terms its 28.70% decline overall.

Types of Inflation

1. Creeping Inflation (Mild)

   • Rate: 1–3% annually.

   • Considered healthy for economic growth.

   • Example: Many developed countries like the USA aim for ~2% inflation.

2. Walking Inflation (Moderate)

   • Rate: 3–10% annually.

   • Can start to hurt savings and investments.

   • Example: India often falls in this range.

3. Running Inflation (High)

   • Rate: 10–20% annually.

   • Savings quickly lose value, and costs rise sharply.

4. Galloping Inflation (Very High)

   • Rate: 20–50% annually.

   • Damages the economy.

5. Hyperinflation (Extreme)

   • Rate: Over 50% monthly.

   • Example: Zimbabwe in 2008, Venezuela from 2016–2019.

Causes of Inflation

Inflation doesn’t happen randomly — it usually arises due to one or more of the following causes:

1. Demand-Pull Inflation

   • Occurs when demand is greater than supply.

   • Example: Festival season shopping leading to higher prices of goods.

2. Cost-Push Inflation

   • Caused by higher costs of raw materials or wages.

   • Example: Rising oil prices increase transport costs, raising the price of almost everything.

3. Monetary Inflation

   • When central banks print more money than needed.

   • Too much money chasing limited goods = price rise.

4. Imported Inflation

   • Countries dependent on imports face inflation if global prices rise.

   • Example: India’s dependency on crude oil.

How Inflation is Measured

Governments use different price indices to measure inflation:

• Consumer Price Index (CPI): Measures the change in the price of a basket of consumer goods (food, clothing, rent, fuel).

• Wholesale Price Index (WPI): Measures changes in wholesale prices before they reach consumers.

• Producer Price Index (PPI): Measures average change in selling prices by domestic producers.

Example:

If CPI rises from 200 to 210 in a year:

Inflation Rate = 210-200/200*100 = 5%

Inflation Formula & Calculations

The general formula is:

Inflation Rate (%) = CPI Current Year – CPI Previous Year/CPI In Previous Year *100

Example 1: Annual Inflation

• CPI in 2024 = 180

• CPI in 2025 = 192

Inflation Rate (%) = 192-180/180*100 = 6.67%

Example 2: Purchasing Power Decline

If ₹10,000 is kept idle for 15 years at 6% average inflation:

Future Value = 10000/(1.06)^15 ≈ 4,174

That means ₹10,000 today will only be worth ₹4,174 after 15 years.

Real-World Case Studies

1. India

   • Average inflation: 5–7% annually over decades.

2. USA

   • 1970s: High inflation due to oil shocks.

   • Federal Reserve now targets ~2% inflation.

3. Zimbabwe (2008)

   • Hyperinflation: Prices doubling daily.

   • 100 trillion Zimbabwean dollar notes were issued.

4. Venezuela (2016–2019)

   • Hyperinflation exceeded 1,000,000%.

   • People switched to US dollars and cryptocurrencies.
