What is Interest Rate Risk

Interest rate risk can reduce the selling price of your bond when new bonds start offering higher interest. The risk becomes more important if you need your money before the bond's maturity date.

• If interest rates rise, existing bond prices generally fall.
• If interest rates fall, existing bond prices generally rise.
• A ₹1 lakh bond paying 5% gives ₹5,000 interest per year.
• If new bonds start paying 6%, buyers may prefer those bonds.
• Longer-term bonds generally face bigger price changes than shorter-term bonds.
• Holding bonds with different maturity dates can reduce concentration in one interest-rate period.

Yes. Rising interest rates can reduce the market price of a bond you already own.

Suppose your bond pays 5% interest. Later, new bonds start paying 6%.

A buyer may ask, "Why should I buy your 5% bond when I can get 6% from a new bond?"

To attract that buyer, you may need to sell your bond at a lower price.

This is interest rate risk.

Understand it with example

Suppose you invest ₹1 lakh in a bond.

The coupon rate tells you how much interest the bond pays.

Your annual interest is:

₹1 lakh × 5% = ₹5,000

A new ₹1 lakh bond paying 6% gives:

₹1 lakh × 6% = ₹6,000

The new bond gives ₹1,000 more interest per year.

Your old bond does not stop paying ₹5,000. However, its market price may fall because buyers can now get a higher rate elsewhere.

Interest rate risk matters more when you want to sell your bond before maturity.

If you need cash urgently, you may have to accept the market price available at that time.

Consider Ramesh, a 36-year-old auto driver in Nagpur.

He earns ₹32,000 per month and invests ₹1 lakh in a bond paying 5% interest per year.

After some time, market rates rise to 6%. Ramesh suddenly needs money to repair his auto.

If he sells the bond before maturity, he may get less than ₹1 lakh because buyers can now buy newer bonds paying a higher rate.

This is why the timing of your money need matters.

New bonds become more attractive when they offer higher interest.

Suppose your bond pays 5%, but a new bond pays 6%.

Most buyers will prefer the 6% bond if both look similar in other ways.

Your older bond may need a lower selling price to attract a buyer.

The reverse can also happen.

If new bonds start paying only 4%, your old 5% bond may look more attractive.

Yes. Longer-term bonds generally react more to changes in interest rates.

A bond that matures soon has less time left for the rate difference to matter.

A bond with many years remaining can see a bigger price movement.

Investors use a measure called duration to understand this sensitivity.

Duration tells you how strongly a bond's price can react when interest rates change.

Does this mean your bond stops paying interest?

No. A change in market interest rates does not automatically change the coupon promised by your existing fixed-rate bond.

If your bond pays 5%, it continues to pay according to its terms.

The main change happens in the bond's market value.

This becomes important when you want to sell it before maturity.

First ask one simple question: Do you actually need the money now?

If you do not need to sell, a temporary market-price fall may matter differently to you.

Before selling a bond, check:

• How much time remains until maturity
• Your bond's coupon rate
• Current market interest rates
• The selling price available
• Whether you urgently need cash
• The financial strength of the bond issuer

A rate increase alone should not decide your action.

How can you reduce interest rate risk?

You can avoid putting all your bond money into one maturity period.

For example, instead of investing the full amount in long-term bonds, you can spread it across bonds that mature at different times.

This is called maturity diversification.

It means all your money does not depend on the same interest-rate situation.

Advanced investors may also use:

• Interest-rate futures
• Forward contracts
• Options
• Interest-rate swaps

These products are more complex and carry their own risks.

Yes. Higher interest rates can increase the cost of borrowing for companies.

Businesses often borrow money to buy machinery, build factories, expand operations, or manage daily expenses.

Higher borrowing costs can affect:

• Interest expenses
• Cash flow
• New projects
• Business expansion
• Profit

Companies with more debt can feel the impact more strongly.

Interest rate risk matters because rising market rates can reduce the selling price of your existing bond.

The risk matters more if you need to sell before maturity. Longer-term bonds also generally react more to rate changes.

Before investing, check how long you can keep your money invested. If you may need the money soon, understand how a change in interest rates can affect the price you receive.
