Interest Rate

An interest rate is the percentage charged on borrowed money (or earned on deposited/lent money) over a specific period. Interest rates are the most fundamental price in any economy — they influence everything from your home loan EMI to the valuation of stocks on the NSE.

In India, the benchmark interest rate is the repo rate set by the RBI's Monetary Policy Committee (MPC), which meets six times a year. As of recent years, the repo rate has ranged between 4.00% and 6.50%. When the RBI raises the repo rate, borrowing becomes more expensive, slowing economic activity and cooling Inflation. When it cuts, credit becomes cheaper, stimulating growth.

Interest rates directly impact fixed-income investments. When rates rise, existing bond prices fall (because new bonds offer higher yields, making old bonds less attractive). Conversely, when rates fall, existing bond prices rise. This inverse relationship is critical for anyone holding debt Mutual Funds, government securities, or corporate bonds.

For equity markets, interest rates work through multiple channels. Higher rates increase the cost of capital for companies, compress profit margins, and reduce the present value of future earnings — all negative for stock valuations. The Nifty 50 historically shows weakness in rate-hiking cycles and strength in rate-cutting cycles.

Consider the impact on a home loan: a ₹50,00,000 home loan at 8.5% over 20 years has an EMI of approximately ₹43,400. If the rate drops to 7.5%, the EMI falls to ₹40,300 — saving ₹3,100 per month or ₹7,44,000 over the loan tenure. This is why RBI rate decisions are closely watched by millions of Indian borrowers.
