A bond discount happens when the market price of a bond is lower than its original face value. When a bond is first issued, it has a set price called the par value, which is usually 1,000 rupees in India. If you can buy that same bond on the stock exchange for 950 rupees, it is trading at a discount of 50 rupees. This usually occurs when the interest rate offered by the bond is lower than the current market interest rates. Investors buy bonds at a discount because it allows them to earn a higher overall return, as they pay less now but still receive the full face value when the bond matures.

What is a Bond Discount?

To understand a bond discount, you first need to know how bonds are priced. Every bond has a starting price called the face value. This is the amount of money the borrower promises to pay you back at the end of the bond term. However, once a bond starts trading on the National Stock Exchange (NSE) or Bombay Stock Exchange (BSE), its price can move up or down every day.

If the price moves below the face value, we call it a bond discount. For example, if a government bond has a face value of 100 rupees but is selling for 98 rupees, the 2 rupee difference is the discount. This is like buying a product on sale. You pay a smaller amount today, but you still get the full benefits of the bond, including all the interest payments and the full 100 rupees at the end.

Why do Bonds Trade at a Discount?

There are several reasons why a bond price might fall below its face value in the Indian market.

1. Rising Interest Rates

This is the most common reason. Imagine you have a bond that pays 7 percent interest. If the Reserve Bank of India (RBI) increases interest rates and new bonds start paying 9 percent, no one will want to buy your 7 percent bond at the full price. To attract a buyer, you must lower the price of your bond. This lower price creates a discount.

2. Credit Rating Downgrade

Bonds are rated by agencies like CRISIL or ICRA based on the safety of the borrower. If a company's financial health becomes weak, its credit rating might be lowered. Investors feel there is more risk, so they demand a lower price to buy the bond.

3. Time to Maturity

As a bond gets closer to its maturity date, its price usually moves closer to the face value. If a bond was trading at a deep discount because of high interest rates, the discount will slowly disappear as the final payment date approaches.

4. Low Demand

If there are many sellers in the market but very few buyers on the NSE or BSE, the price will naturally drop. This creates a discount for those who are willing to buy.

How to Calculate a Bond Discount

Calculating the discount is very simple. You just need to know the face value and the current market price.

Bond Discount = Face Value - Market Price

If you want to find the discount as a percentage, you use this formula:

Discount Percentage = (Bond Discount / Face Value) x 100

Example:

Suppose a corporate bond has a face value of 1,000 rupees. Because market interest rates have gone up, the bond is trading at 920 rupees on the stock exchange.

Bond Discount = 1,000 - 920 = 80 rupees.
Discount Percentage = (80 / 1,000) x 100 = 8 percent.

The Link Between Discount and Yield

The most important thing for an investor to understand is that bond price and bond yield move in opposite directions. When a bond is at a discount, the yield goes up.

Yield is the actual return you get on your money. If you buy a bond at a discount, you make money in two ways:

You get the regular interest payments (coupons).
You make a profit because you bought the bond for 920 rupees but will get 1,000 rupees back at the end.

Because of this extra profit from the price difference, a discounted bond always has a higher yield than its stated coupon rate. This is why many experienced investors look for discounted bonds on the NSE and BSE.

Comparison: Discount Bond vs. Premium Bond

It is helpful to see how a discount bond differs from a premium bond, which is a bond that sells for more than its face value.

Feature	Discount Bond	Premium Bond
Market Price	Lower than Face Value.	Higher than Face Value.
Market Interest Rates	Higher than the bond's coupon.	Lower than the bond's coupon.
Actual Yield (YTM)	Higher than the coupon rate.	Lower than the coupon rate.
Capital Gain	Positive (Price goes up to par).	Negative (Price falls down to par).
Reason for Buying	To get a higher total return.	To get a high regular coupon.

Benefits of Buying Bonds at a Discount

Higher Total Return: You get the interest plus the profit from the price increase as the bond reaches maturity.
Lower Initial Cost: You can start investing with less money than the actual face value of the bond.
Safety Margin: If you buy a bond for 900 rupees that is worth 1,000 rupees, you have a small cushion if the market price fluctuates slightly.
Predictable Growth: As long as the borrower is safe, you know for sure that your 900 rupees will turn into 1,000 rupees by the maturity date.

Risks to Consider

Even though buying at a discount sounds like a bargain, you should be careful about these points:

1. Default Risk

Sometimes a bond is at a deep discount because investors are afraid the company might not pay the money back. Always check the credit rating. A bond from a weak company at a 20 percent discount is much riskier than a government bond at a 2 percent discount.

2. Liquidity Risk

Some discounted bonds on the stock exchange have very few trades. If you want to sell your bond quickly, you might not find a buyer at a fair price.

3. Interest Rate Risk

If interest rates keep going up even after you buy the bond, the price could fall further. This only matters if you want to sell the bond before it matures.

Taxation of Bond Discounts in 2026

The profit you make from a bond discount is usually treated differently than the regular interest.

Interest Income: The yearly interest you receive is added to your total income and taxed according to your tax slab.
Capital Gains: The profit you make because the bond price moved from 920 to 1,000 is often treated as a capital gain. If you hold the bond for more than 12 months, you might pay a lower tax rate on this profit.

It is always a good idea to check with a tax expert because rules can change depending on whether the bond is a zero coupon bond or a regular corporate bond.

The Role of NSE and BSE

The National Stock Exchange and Bombay Stock Exchange are the places where you can find these discounted bonds. You can look at the debt segment of their websites to see the live prices. The exchanges provide data like the last traded price and the volume of trades. This helps you see which bonds are available at a discount and how easy they are to buy. By using the official NSE and BSE data, you can be sure that the discount you see is based on real market trades.

Conclusion

A bond discount is a great opportunity for investors to get more value for their money. It allows you to buy a future payment of 1,000 rupees for a cheaper price today. While a discount often happens because interest rates have gone up, it can also happen due to market demand or credit changes. By understanding how to calculate the discount and checking the safety of the borrower through credit ratings, you can build a stable and profitable investment portfolio. Whether you are buying government T-Bills or corporate NCDs on the NSE and BSE, knowing the math of bond discounts will help you make smarter choices for your wealth in 2026.

Frequently Asked Questions (FAQs)

Is a bond discount a bad sign for a company?

Not always. Most of the time, a bond discount happens because general interest rates in the country have gone up, which is not the company fault. However, if the discount is very deep, it might mean the company is in financial trouble.

Does the discount change every day?

Yes, as the market price of the bond moves on the stock exchange, the discount will also change.

What is the difference between a discount and a coupon?

A coupon is the regular interest the bond pays. A discount is the difference between the face value and the lower price you paid to buy the bond.

Will I get the full discount profit if I sell the bond early?

No, you only get the full profit from the discount if you hold the bond until the maturity date when the borrower pays the full face value.

Are zero coupon bonds always sold at a discount?

Yes, zero coupon bonds must be sold at a discount because they do not pay any regular interest. The discount is the only way the investor makes a profit.

Can a government bond be at a discount?

Yes, government bonds (G-Secs) often trade at a discount on the NSE if the market interest rates are higher than the bond coupon rate.

Is a discount bond the same as a junk bond?

No. Junk bonds are bonds with very low credit ratings. While many junk bonds trade at a discount, even the safest AAA-rated bonds can trade at a discount if interest rates rise.

What happens to the discount as the bond matures?

As the maturity date gets closer, the market price of the bond will slowly rise toward the face value, meaning the discount will decrease to zero.

How can I find discounted bonds on the NSE?

You can visit the debt segment on the NSE website and look at the list of traded bonds. Compare the LTP (Last Traded Price) with the Face Value.

Do I need a demat account to benefit from bond discounts?

Yes, you need a demat account to buy and hold bonds traded on the stock exchange where these discounts are available.
