Interest Rate
in-truhst rayt
An Interest Rate represents the cost of using money.
For a borrower, it is the price paid for borrowing funds.
For a saver or investor, it is the return earned for providing funds.
Interest rates are commonly expressed as an annual percentage.
For example, if a person borrows ₹1 lakh at an interest rate of 8% per year, the simple annual interest would be:
₹1,00,000 × 8% = ₹8,000
Interest rates apply to many financial products, including:
- Home loans
- Personal loans
- Education loans
- Credit cards
- Fixed deposits
- Savings accounts
- Bonds
- Other lending and investment products
Interest rates can be:
- Fixed – the rate remains unchanged for a specified period
- Floating or variable – the rate can change over time based on a benchmark or market conditions
The level of an interest rate can depend on factors such as:
- Inflation
- Central bank policy
- Credit risk
- Loan duration
- Market demand for funds
- Economic growth
- Borrower profile
Interest rates are also important at the economy-wide level. Central banks use policy interest rates to influence borrowing, spending, inflation, and economic activity.
A rise in interest rates generally makes borrowing more expensive and may encourage saving, while lower rates can make borrowing cheaper and may support spending and investment.
Effect of a Higher Loan Interest Rate
Ravi takes a loan of ₹5 lakh.
Suppose the loan carries an annual interest rate of 9%.
The simple annual interest would be:
₹5,00,000 × 9% = ₹45,000
If the interest rate later rises to 11% on a floating-rate loan, the interest cost would increase.
At 11%, the simple annual interest would be:
₹5,00,000 × 11% = ₹55,000
This means Ravi’s borrowing cost increases by ₹10,000 per year, before considering repayment structure and reducing loan balance.
This shows why changes in Interest Rates can directly affect loan costs, household budgets, and financial decisions.
2008 – Global Interest Rate Cuts Post-Lehman Crisis
When it happened: Late 2008 onward
How it happened: Central banks slashed rates to near zero to boost liquidity and prevent depression.
2010s – Negative Interest Rates in Europe and Japan
When it happened: Post-2014
How it happened: ECB and BoJ adopted negative policy rates to fight deflation and revive lending.
2022 – Global Rate Hikes to Tame Post-COVID Inflation
When it happened: Mid-2022 onward
How it happened: RBI, Fed, ECB raised rates sharply to counter price surges post-pandemic stimulus.
