Zero Coupon Bonds: Bonds Issued at a Discount with No Periodic Coupon Payments

Zero Coupon Bonds are a type of fixed-income security issued at a discount and repay principal at maturity without periodic interest payments. They can still yield positive returns if purchased at a deep discount.

Zero Coupon Bonds, often called “zeroes,” are a type of fixed-income security issued at a discount to their face value. Unlike traditional bonds, Zero Coupon Bonds do not make periodic interest payments (coupons). Instead, they provide all their returns at maturity when the bondholder receives the face value of the bond.

Characteristics of Zero Coupon Bonds

Issuance at a Discount

Zero Coupon Bonds are typically issued at a price significantly lower than their face value. For instance, a bond with a face value of $1,000 might be sold for $500, reflecting the lack of interest payments.

Absence of Periodic Interest Payments

Unlike traditional bonds, Zero Coupon Bonds do not pay interest periodically. The bondholder’s return is realized entirely at maturity, when the bond’s face value is repaid.

Yield Calculation

The yield of a Zero Coupon Bond is calculated by comparing its purchase price to its face value, considering the time to maturity. The formula for Yield to Maturity (YTM) on Zero Coupon Bonds is:

$$ YTM = \left( \frac{F}{P} \right)^{\frac{1}{n}} - 1 $$

where \( F \) is the face value, \( P \) is the purchase price, and \( n \) is the number of years to maturity.

Types of Zero Coupon Bonds

Treasury Zero Coupon Bonds

Government-issued bonds, such as U.S. Treasury STRIPS (Separate Trading of Registered Interest and Principal Securities), are among the safest types of zeroes.

Municipal Zero Coupon Bonds

These are issued by state and local governments but may offer tax-free interest, making them attractive to certain investors.

Corporate Zero Coupon Bonds

Issued by corporations, these bonds may offer higher yields due to increased risk compared to government bonds.

Considerations and Examples

Price Volatility

Zero Coupon Bonds are more sensitive to interest rate changes compared to traditional bonds because they do not provide periodic interest payments that mitigate interest rate risk.

Tax Implications

Even though Zero Coupon Bonds do not pay periodic interest, the imputed (phantom) interest must be reported as income annually for tax purposes. This can create a tax liability even though the bondholder does not receive cash until maturity.

Example

Consider a Zero Coupon Bond with a face value of $1,000 maturing in 10 years, purchased for $600. The yield would be calculated as:

$$ YTM = \left( \frac{1000}{600} \right)^{\frac{1}{10}} - 1 \approx 5.24\% $$

Historical Context

Zero Coupon Bonds have been used since the 1960s and gained popularity in the 1980s with the advent of U.S. Treasury STRIPS. They are widely used for long-term goals like retirement or education funding due to their predictable maturation values.

Applicability

Zero Coupon Bonds are suitable for investors with long-term investment horizons who can avoid the need for periodic income. They are frequently used for dedicated financial goals where the maturity date of the bonds aligns with the investor’s financial needs.

Comparisons

Zero Coupon Bonds vs. Traditional Bonds

• Interest Payments: Traditional bonds pay periodic interest, while Zero Coupon Bonds do not.
• Price Volatility: Zeroes are more sensitive to interest rate changes.
• Tax Reporting: Traditional bonds report interest income annually, while zeroes report imputed interest.

Related Terms

• Coupon Rate: The periodic interest paid by bonds, absent in Zero Coupon Bonds.
• Yield to Maturity (YTM): The total expected return if the bond is held until maturity.
• Discount Rate: The interest rate used to discount future cash flows of a bond.

FAQs

What is the main benefit of investing in Zero Coupon Bonds?

The primary benefit is their predictability and potential for earning a higher yield compared to regular bonds if bought at a significant discount.

Are Zero Coupon Bonds risk-free?

While government-issued zeroes like Treasury STRIPS are considered low-risk, corporate or municipal zeroes carry higher credit risk. Additionally, they are highly sensitive to interest rate changes.

How are Zero Coupon Bonds taxed?

Even though they don’t pay periodic interest, investors must account for imputed interest income annually on their tax returns.
