Inflation and Interest Rate – Are they Related?
Interest rate affects inflation and both are closely related. They are generally referred together in macroeconomics. In this article, we look at the differences between Interest Rates and Inflation.
What is Inflation?
Inflation is the rate at which the general level of prices for goods and services rise. As for price increase, this leads to falling in purchasing power of the currency. It is very much necessary to keep inflation rate within permissible limits for the smooth functioning of an economy.
Let us understand inflation with example- Suppose in 1990 a man buys petrol daily of INR 100 for his car and price of one liter was INR 40, in INR 100 he gets 2.5 Litres of petrol and now, if he buys petrol of INR 100 considering the current rate of petrol INR 90 per liter, he will get 1.1 L of petrol. Although INR 100 remain the same but its purchasing power decreased in 28 years earlier, he gets 2.5L petrol at the same price as today’s 1.1L of petrol. This is called inflation.
What is Interest Rate?
The interest rate is the rate at which the lender is lending funds to the borrower. The interest rate has a vital impact on the economy of the country and has a major impact on stock and other investment.

The interest rate is decided by considering two factors.
- Capital availability, if a rate of interest is high then capital is costly.
- If the rate of interest is low, bank customer will not get sufficient return on their fund which will demotivate customer to keep the amount in the bank as a result bank will not have funds.
If money is cheap, people will get the motivation to get money in the market and as a result value of money will decrease. This will increase inflation.
The rate of interest for loans and deposit are different. The rate of interest for loans are high whereas for deposits comparatively less. The interest rate is a price for holding or loaning money i.e. price for depositing or borrowing of money.
Inflation vs Interest Rate Relationship Infographics
Here we provide you with the top relationship between Inflation and Interest Rate
To understand the relationship between inflation vs interest rate better it’s important to know about the Quantity Theory of Money.
The relationship between Inflation and Interest Rate
- Quantity Theory of Money determines that supply and demand for money determine inflation. If the money supply increases, as a result, inflation increase and if money supply decreases lead to a decrease in inflation.
- This principle is applied to study the relationship between inflation vs interest rate where when the interest rate is high, supply for money is less and hence inflation decrease which means supply is decreased whereas when the interest rate is decreased or low, supply of money will be more and as a result inflation increase that means that demand is increased.
- In order to control high inflation, the central bank increases the interest rate. When interest rate increases, the cost of borrowing rises. This makes borrowing expensive. Hence, borrowing will decrease and the money supply will fall. A fall in money supply in the market will lead to a decrease in money with people to expense on goods and services. With the supply constant and the demand for goods and service will decrease which leads to falling of the price of goods and services.
- In a low inflationary situation, the rate of interest reduces. A decrease in the rate of interest will make borrowing cheaper. Hence, borrowing will increase and the money supply will increase. With a rise in the money supply, people will have more money to spend on goods and services. So, demand for goods and services will increase and with supply remaining constant this leads to a rise in the price level and that is inflation.
Hence, they are inversely related to each other and have its own impact. As describe above if an interest rate is high, then inflation and money circulation in a market will be low and if an interest rate is less, then money circulation will be high in a market and hence inflation will increase.
Interest vs Inflation – Inverse Relationship?
Let’s now look at the head to head difference relationship between Inflation and Interest Rate
|Basis for Relationship between Interest Rate vs Inflation||Interest Rate||Inflation|
|Effect of Increase||If interest rate increase, inflation decreases||If inflation increase, interest rate decreases|
|Money Circulations in market decreases||Money Circulations in market increases|
|Borrowing became expensive||Borrowing became cheap|
|Demand for goods & services decrease||Demand for goods & services increase|
|Interest rate increase leads to falling of price of services and goods||Inflation leads to a rise in the price of service and goods|
|Effect of Decrease||If interest rate decrease, inflation increases||If inflation decreases, interest rate increase|
|Money Circulations in market increases||Money Circulations in market decreases|
|Borrowing became cheap||Borrowing became expensive|
|Demand for goods & services increase||Demand for goods & services decrease|
|Interest rate decrease leads to a rise in the price of services and goods||Inflation decrease leads to falling of price of services and goods|
Above we can see the relationship between the inflation vs interest rate. Through this, we can say that Inflation vs Interest rate is dependent on each other and the relation between them is an inverse relationship where one increase and other decrease and vice versa.
Inflation effect price of goods and services and these prices are very important for the customer as well for the seller as they want secure inflation where prices are stable or if in case it increases it should increase gradually. The purchasing power of their currency should not effect. Price stability is very much needed for a healthy economy. Considering this interest rate is decided. As to control inflation interest rate needed to change after a regular interval to maintain a healthy economy. Inflation vs Interest rate has a vital role in a market it helps the investor to calculate how much return his investment need to make maintain his standard of living and investor invests in a product that gives return more than of inflation.
