What are Zero-Coupon Bonds?

Zero-coupon bonds are a unique type of debt instrument where the issuer does not make periodic interest payments (or coupons) to the bondholder. Instead, these bonds are issued at a deep discount to their face value, and the investor receives the full face value of the bond at maturity. The difference between the purchase price and the face value represents the bond's interest income.

In essence, zero-coupon bonds are "discounted" bonds that do not pay regular interest during the life of the bond but instead accumulate interest until maturity.

How Do Zero-Coupon Bonds Work?

• Purchase Price: Zero-coupon bonds are sold at a discount to their face value. For example, a bond with a face value of ₹1,000 might be sold for ₹600.

• Maturity: At maturity, the investor receives the full face value of the bond. In this example, the investor who bought the bond for ₹600 will receive ₹1,000 when the bond matures.

• No Periodic Interest: Unlike traditional bonds that pay regular interest (usually semi-annually or annually), zero-coupon bonds do not pay any interest during the life of the bond.

• Implied Interest: The difference between the purchase price and the face value represents the implied interest. The return to the investor is essentially the accumulation of interest over the bond's term, which is paid out at the bond's maturity.

Key Features of Zero-Coupon Bonds

1. Issued at a Discount:

   • Zero-coupon bonds are issued at a price lower than their face value. For example, if the face value is ₹1,000, the bond may be issued at ₹700, and upon maturity, the investor will receive ₹1,000.

2. No Coupon Payments:

   • These bonds do not provide periodic interest payments like traditional bonds. The bondholder receives the face value of the bond only at maturity.

3. Longer Duration:

   • Zero-coupon bonds generally have longer maturity periods, ranging from a few years to decades. The longer the maturity period, the greater the difference between the issue price and the face value.

4. Capital Gain:

   • The return on a zero-coupon bond comes from the capital gain — the difference between the purchase price and the face value received at maturity.

5. Types of Zero-Coupon Bonds:

   • Government Zero-Coupon Bonds: These are issued by governments and are considered low-risk investments. For instance, in India, Government Savings Bonds can be structured as zero-coupon bonds.

   • Corporate Zero-Coupon Bonds: These are issued by corporations and carry a higher risk compared to government bonds. They offer higher returns to compensate for the increased risk.

Advantages of Zero-Coupon Bonds

1. Predictable Return:

   • Zero-coupon bonds are predictable because the return is the difference between the issue price and the face value. If the bond is held to maturity, the investor knows exactly how much they will receive.

2. No Reinvestment Risk:

   • Since zero-coupon bonds do not make periodic interest payments, there is no reinvestment risk. In regular bonds, the interest payments need to be reinvested, and if interest rates fall, reinvested interest may earn lower returns.

3. Potential for High Returns:

   • Because zero-coupon bonds are purchased at a discount and appreciated over time, they have the potential for significant capital gains if held until maturity.

4. Lower Initial Investment:

   • Since these bonds are issued at a discount, the initial investment is lower than the face value. This can make them more accessible for smaller investors.

5. Tax-Deferred Growth:

   • In some countries, such as the U.S., the imputed interest on zero-coupon bonds is considered to be tax-deferred. Investors pay taxes only when the bond matures or is sold, not on the annual accrual of interest.

Disadvantages of Zero-Coupon Bonds

1. No Regular Income:

   • Zero-coupon bonds do not offer any regular interest income, making them less suitable for investors who need periodic income (such as retirees). The only payout occurs at maturity.

2. Long-Term Investment:

   • These bonds generally have longer maturities, which means investors need to wait many years (sometimes decades) before receiving the face value. This could be a drawback for those needing liquidity.

3. Taxable Income:

   • In many countries, the accrued interest on zero-coupon bonds is considered taxable income, even though the interest is not received until maturity. This means investors might face tax liability annually, even though they haven't received any cash.

4. Price Sensitivity:

   • Zero-coupon bonds are more sensitive to interest rate fluctuations than bonds with regular interest payments. If interest rates rise, the price of a zero-coupon bond may fall significantly, particularly for long-term bonds.

5. Risk of Default:

   • Just like any bond, zero-coupon bonds are subject to the risk of issuer default. Corporate zero-coupon bonds are riskier than government-issued zero-coupon bonds.

Taxation of Zero-Coupon Bonds

The taxation of zero-coupon bonds varies by country. Here’s how they are typically taxed in India:

1. Tax on Interest:

   • In India, zero-coupon bonds are taxed as income. Even though no interest is paid out, the imputed interest (the difference between the issue price and the maturity value) is considered taxable income.

   • This imputed interest is subject to taxation in the year it accrues, even though it is not received until maturity.

2. Capital Gains Tax:

   • If the zero-coupon bond is sold before maturity, the capital gain (the difference between the selling price and the purchase price) is taxed.

   • The capital gain is classified as short-term (if held for less than 36 months) or long-term (if held for more than 36 months).

   • Long-term capital gains are taxed at 20% with indexation or 10% without indexation (whichever is more beneficial).

   • Short-term capital gains are taxed as per the investor's income tax slab.

Examples of Zero-Coupon Bonds

1. Government Zero-Coupon Bonds:

   • Sovereign Gold Bonds (SGBs): While primarily not considered zero-coupon bonds, these bonds are issued at a discount and accrue interest, which is paid at maturity.

   • Government Savings Bonds: Some government-issued bonds are zero-coupon bonds that provide a lump-sum payout at maturity.

2. Corporate Zero-Coupon Bonds:

   • Corporate Zero-Coupon Bonds are issued by corporations and typically carry a higher risk than government bonds. They are issued at a discount and mature at face value, providing the investor with the return over time.

Who Should Invest in Zero-Coupon Bonds?

Zero-coupon bonds are ideal for:

1. Long-Term Investors: If you're looking for a fixed, guaranteed return and can wait for a long period (often 5 to 30 years), zero-coupon bonds are an attractive choice.

2. Those Seeking Tax Deferral: If you're in a country where tax on the accrued interest is deferred until maturity, zero-coupon bonds may be beneficial.

3. Investors Without a Need for Regular Income: These bonds are suitable for individuals who do not require periodic income but are looking for a lump sum payout in the future.

4. Risk-Averse Investors: Government-issued zero-coupon bonds, like Treasury Bonds, can be a good option for conservative investors who want a safe, long-term investment with guaranteed returns.

Conclusion

Zero-coupon bonds are an interesting investment instrument for those looking for a long-term, lump sum return without the need for regular interest payments. They are issued at a discount and pay the full face value at maturity. While they offer advantages like predictable returns and tax-deferred growth in some countries, they also come with risks such as tax implications and sensitivity to interest rate changes. They are best suited for investors who can lock in their money for an extended period and do not require regular income.
