Strip Bonds: Definition, Scenarios, and Benefits


Strip bonds, also known as zero-coupon bonds, are unique debt instruments where the principal and coupon payments are separated and sold individually. In this article, we explore the definition of strip bonds, how they work, how they are priced, and their tax implications. We’ll also discuss the benefits and drawbacks of investing in strip bonds.

Understanding strip bonds

Strip bonds, often referred to as zero-coupon bonds, are a distinctive type of debt instrument. Unlike conventional bonds, they do not make regular interest payments to investors. Instead, both the principal and coupon payments are separated and sold separately as individual securities. Let’s delve deeper into the world of strip bonds and understand how they function.

How do strip bonds work?

When it comes to conventional bonds, also known as coupon bonds, investors typically receive regular interest payments along with the repayment of their principal investment upon maturity. These interest payments are commonly referred to as “coupons.” Investors may purchase these bonds at par value, at a discount, or at a premium.

However, not all bonds operate this way. Strip bonds take a different approach. Investment firms or dealers acquire a debt instrument and “strip” it by separating the coupon payments from the principal amount. The principal, now known as the “residue,” and the coupons are then sold as new securities to investors.

One notable feature of strip bonds is that they have no reinvestment risk. This is because no interest or coupon payments are made before the bond’s maturity date. Investors who opt for strip bonds are essentially making a long-term investment with the expectation of receiving their returns when the bond matures.

On the maturity date, investors who hold the residue will receive an amount equal to the face value of the bond. The difference between the purchase price of the bond and the face value at maturity represents the investor’s return on the investment.

For example, if an investor purchased a bond residue for $3,200 with a face value of $5,000 that matures in five years, their return at maturity would be $5,000 – $3,200, which equals $1,800.

Another scenario involves investors who purchase the coupon payments instead of the residue. These investors receive one of the bond’s original semi-annual interest or coupon payments. If the bond has a coupon rate of 4%, the interest payment can be calculated as (4% ÷ 2) x $5,000, resulting in $100. The investor’s cost is ($3,200 ÷ $5,000) x $100, which equals $64. Their return at maturity would be $100 – $64, which equals $36.

How strip bonds are priced

The market price of a strip bond is influenced by several factors. The issuer’s credit rating plays a role, as does the present value of the maturity amount. This present value is determined by the time to maturity and the prevailing interest rates in the economy.

In general, the farther away from the maturity date, the lower the present value, and vice versa. When interest rates in the economy are low, the present value of strip bonds is higher, and vice versa. Unlike regular bonds, strip bonds don’t have periodic interest payments to stabilize their value. Consequently, their value can fluctuate significantly with changes in prevailing interest rates.

This sensitivity to interest rate fluctuations is known as the bond duration. It’s typically higher for strip bonds compared to coupon bonds. Due to the absence of regular interest payments, strip bonds are often traded at a deep discount to their face value.

Special considerations: Strip bonds and taxes

It’s important to note that if a strip bond is held until maturity, the returns earned are taxable as interest income. Even though bondholders do not receive interest income throughout the bond’s life, they are still required to report the imputed or phantom interest to the Internal Revenue Service (IRS) each year. This imputed interest adds to the cost basis of the bond, which can impact the tax implications when the bond is eventually sold before maturity.

Pros and cons of strip bonds

Weigh the risks and benefits

Here is a list of the benefits and drawbacks to consider.

  • Investors can buy the residue and receive the face value of the bond at maturity.
  • No reinvestment risk as there are no interest payments before maturity.
  • Potential for capital appreciation if interest rates decrease.
  • No regular income in the form of coupon payments.
  • Imputed interest is taxable, impacting the overall return.
  • Value of strip bonds can be highly sensitive to interest rate fluctuations.

Strip bonds: An investment strategy

Strip bonds, also known as zero-coupon bonds, can be an intriguing addition to your investment portfolio. Understanding how they can fit into your overall strategy is crucial.

Strategies for investing in strip bonds

Investors have various approaches to incorporating strip bonds into their investment strategy. Let’s explore a few strategies:

1. Diversification

Diversifying your portfolio with strip bonds can be a smart move. These bonds are often less correlated with other asset classes, making them a potential hedge against market volatility.

For example, if you have a diversified portfolio of stocks and traditional bonds, adding strip bonds can help reduce overall risk. During economic downturns, the capital appreciation potential of strip bonds can offset losses in the equity market.

2. Retirement planning

Strip bonds can play a vital role in retirement planning. Their no-reinvestment-risk feature means you can rely on a steady payout upon maturity. For example, if you’re nearing retirement and want a stable source of income, you can invest in strip bonds that mature during your retirement years.

Example scenarios

To illustrate the potential benefits of strip bonds in various scenarios, let’s consider a few examples:

Scenario 1: college savings

Imagine you’re a parent saving for your child’s college education. You have 15 years until your child starts college. You decide to invest in strip bonds with maturities coinciding with your child’s freshman year. By the time your child enrolls, the strip bonds have matured, providing you with the funds needed for tuition and expenses.

Scenario 2: retirement income

Suppose you’re approaching retirement and need a predictable income stream. You invest in a series of strip bonds maturing at regular intervals during your retirement years. This ensures a consistent flow of funds to cover living expenses.

Risk management and strip bonds

Managing interest rate risk

One of the key considerations when investing in strip bonds is managing interest rate risk. Since the value of strip bonds is highly sensitive to interest rate fluctuations, you may want to consider the following strategies:

1. Laddering

Laddering involves purchasing strip bonds with different maturities. By doing so, you can spread your risk and minimize the impact of interest rate fluctuations. If rates rise, the impact on the value of your shorter-term bonds will be less than on longer-term bonds.

2. Holding to maturity

Investors who hold strip bonds until maturity are less affected by interest rate fluctuations. The imputed interest on the bond is locked in at the time of purchase, making their returns relatively stable.


In conclusion, strip bonds, or zero-coupon bonds, offer unique investment opportunities. Strategies for incorporating strip bonds into your portfolio can range from diversification to retirement planning. Proper risk management is essential, and laddering or holding to maturity can help mitigate the effects of interest rate fluctuations. Understanding these strategies and applying them to your financial goals can make strip bonds a valuable addition to your investment toolbox.
