Financial markets are often filled with complex instruments, and one such instrument that can appear daunting at first glance is a STRIP. In this article, I aim to break down what a STRIP is, its components, how it works, and how it fits into the broader picture of financial instruments. By the end of this article, I hope you’ll have a clear understanding of STRIPs and their role in investing and finance, particularly in the context of the United States.

What is a STRIP?
To begin, a STRIP (Separate Trading of Registered Interest and Principal of Securities) is a type of financial instrument that is derived from a U.S. Treasury bond or note. Essentially, a STRIP is created by separating the principal and interest payments of a bond into individual securities, which are then sold separately. The result is a set of zero-coupon bonds, each of which represents either an individual interest payment or the principal repayment of the original bond. These STRIPs are sold at a discount to their face value and do not pay any interest during their life. Instead, the investor receives the full face value of the STRIP at maturity.
The STRIP market was initially created by the U.S. Treasury as part of a program that allows investors to separate the interest payments and principal of Treasury securities. STRIPs are typically associated with zero-coupon bonds, and the difference between the purchase price and the face value is the investor’s return.
How Do STRIPs Work?
Let’s explore how STRIPs work with an example. Suppose I have a 10-year U.S. Treasury bond with a $1,000 face value, and the bond pays interest annually at a rate of 5%. Over the 10 years, this bond will pay $50 each year in interest. If I were to strip the bond, I would create separate securities for each of the annual interest payments ($50 each year for 10 years), as well as the $1,000 principal repayment at the end of the 10th year.
These individual securities can now be sold separately as zero-coupon bonds. A STRIP that represents an interest payment would have a maturity of one year and pay $50 at the end of that year. The STRIP that represents the principal repayment would have a maturity of 10 years and pay $1,000 at the end of the 10-year period.
Here’s a simple illustration:
| Original Bond | STRIP Type | Maturity | Face Value | Discounted Price |
|---|---|---|---|---|
| U.S. Treasury Bond | Interest Payment | 1 year | $50 | $48 (approx.) |
| U.S. Treasury Bond | Interest Payment | 2 years | $50 | $46 (approx.) |
| U.S. Treasury Bond | Interest Payment | 3 years | $50 | $44 (approx.) |
| U.S. Treasury Bond | Principal Payment | 10 years | $1,000 | $600 (approx.) |
In the above table, the face value of each STRIP is the same as the interest payment or the principal payment, but the price at which these STRIPs are sold is discounted. The discount reflects the fact that STRIPs do not pay any interest until maturity. The actual price will depend on prevailing interest rates, and the discount will decrease as the maturity date gets closer.
Why Invest in STRIPs?
STRIPs offer several advantages for certain types of investors, including:
- Tax Deferral: Since STRIPs do not pay periodic interest, investors are not required to report interest income until maturity. This can be advantageous for investors looking to defer taxes on interest income.
- Zero-Coupon Bond Benefits: STRIPs are essentially zero-coupon bonds, and like other zero-coupon bonds, they provide a fixed return if held to maturity. The return is the difference between the purchase price and the face value.
- Predictable Cash Flow: STRIPs provide a predictable, lump-sum cash flow at maturity, which can be useful for investors with specific financial goals, such as saving for a future expense like college tuition or retirement.
- Risk Reduction: Since STRIPs are backed by the U.S. government, they are considered to be a low-risk investment. U.S. Treasury securities are widely regarded as one of the safest investments in the world.
- Diversification: STRIPs can add diversification to an investment portfolio, particularly for investors looking to balance their exposure to stocks and other more volatile assets.
Risks and Considerations
While STRIPs have their advantages, they also come with certain risks and considerations. Here are some factors to keep in mind:
- Interest Rate Sensitivity: STRIPs are highly sensitive to changes in interest rates. When interest rates rise, the prices of STRIPs fall, and when interest rates fall, STRIPs become more valuable. This makes STRIPs more volatile than other types of Treasury securities.
- Reinvestment Risk: Since STRIPs do not pay any periodic interest, investors may face reinvestment risk. This means that if interest rates fall, they may not be able to reinvest their proceeds at a comparable rate.
- Long-Term Investment: STRIPs are typically long-term investments, and their returns are realized at maturity. This makes them less liquid than other types of investments, and investors may have to hold them for many years before seeing a return.
- Inflation Risk: Inflation can erode the purchasing power of the fixed amount received at maturity. If inflation is higher than expected, the real value of the STRIP’s face value at maturity could be lower.
- Taxation: While the tax deferral benefit is appealing, investors should be aware that STRIPs are subject to “phantom income”. This means that although STRIPs do not make any periodic interest payments, investors must still pay taxes on the imputed interest each year, even though they do not receive any cash flow until maturity.
STRIPs vs. Other Treasury Securities
To better understand STRIPs, it’s helpful to compare them to other types of Treasury securities, such as Treasury bonds, notes, and bills. Here’s a comparison table:
| Feature | Treasury Bonds | Treasury Notes | Treasury Bills | STRIPs |
|---|---|---|---|---|
| Maturity | 10-30 years | 2-10 years | 4 weeks to 1 year | Varies, depends on the original bond |
| Interest Payments | Semi-annual | Semi-annual | No interest | No interest |
| Return | Fixed, periodic | Fixed, periodic | Discounted face value | Discounted face value |
| Taxation | Interest taxed annually | Interest taxed annually | Discount taxed annually | Imputed interest taxed annually |
| Purpose | Long-term investment | Medium-term investment | Short-term investment | Long-term investment |
| Liquidity | High | High | Very High | Low (until maturity) |
How STRIPs Are Priced
The price of a STRIP depends on the discount rate and the time to maturity. To calculate the price of a STRIP, we can use the present value formula for a zero-coupon bond:
P = \frac{F}{(1 + r)^n}Where:
- P is the price of the STRIP
- F is the face value (the amount to be paid at maturity)
- r is the discount rate (based on the current interest rate)
- n is the number of periods (years) until maturity
Let’s say we have a STRIP with a face value of $1,000, a discount rate of 3%, and 5 years to maturity. The price would be calculated as follows:
P = \frac{1000}{(1 + 0.03)^5} = \frac{1000}{1.159274} \approx 863.84Thus, the price of the STRIP would be approximately $863.84.
Conclusion
STRIPs are an interesting and versatile financial instrument, offering a predictable, low-risk return for investors who are willing to hold them until maturity. Whether you’re looking to achieve a long-term financial goal, diversify your portfolio, or simply take advantage of the safety of U.S. Treasury securities, STRIPs can be a useful tool in your investment strategy. However, it’s important to understand the risks involved, especially interest rate sensitivity and tax implications. By understanding STRIPs and their place in the world of financial instruments, you’ll be better equipped to make informed investment decisions.
