What Is a Discount Bond?
A discount bond is a bond that is issued or traded at a price below its face value (par value).
A discount bond is simply a bond that you can buy for less than what it will be worth when it matures. Bonds have a "face value" or "par value" (typically $1,000). If a bond is selling for $950, it is trading at a discount. Bonds trade at a discount for two main reasons: 1. Interest Rates Have Risen: If a bond was issued five years ago with a 3% coupon, and new bonds today pay 5%, no one wants the old 3% bond at full price. The price must drop until its effective yield matches the new 5% rate. 2. Credit Risk: If the company issuing the bond gets into financial trouble, investors will demand a higher return to hold the debt, pushing the price down.
Key Takeaways
- A bond trades at a discount when its coupon rate is lower than prevailing market interest rates.
- Investors buy discount bonds for less than their face value and receive the full face value at maturity.
- The difference between the purchase price and the face value represents part of the investor's return.
- Zero-coupon bonds are a common type of discount bond that pay no interest until maturity.
- A bond's price and its yield move in opposite directions; as yields rise, bond prices fall into discount territory.
- Discount bonds may have different tax treatments depending on whether the discount is original issue discount (OID) or market discount.
How Discount Bonds Work
When you buy a discount bond, your total return comes from two sources: 1. Coupon Payments: The regular interest payments (if any) the bond makes. 2. Capital Appreciation: The "pull to par." As the bond gets closer to its maturity date, its price naturally rises toward the face value ($1,000), because that is what the issuer is legally obligated to pay back. For example, a "Zero-Coupon Bond" pays $0 in interest per year. To make it attractive, it is sold at a deep discount (e.g., $600). You pay $600 today, wait 10 years, and get back $1,000. Your profit is the $400 difference.
Calculating the Price of a Discount Bond
The price of a bond is calculated by discounting its future cash flows (coupons + principal) back to the present value using the current market interest rate. If the market rate (Yield to Maturity) is greater than the bond's Coupon Rate, the bond must trade at a discount. * Coupon < Market Yield → Discount Bond (Price < Par) * Coupon = Market Yield → Par Bond (Price = Par) * Coupon > Market Yield → Premium Bond (Price > Par)
Important Considerations: Taxes
Taxation on discount bonds can be tricky. The IRS often treats the "accretion" (the gradual increase in value from purchase price to par) as taxable interest income each year, even though you don't receive the cash until maturity. This is known as "Original Issue Discount" (OID) tax. This means you might owe taxes on money you haven't received yet. For this reason, many investors prefer holding zero-coupon or deep-discount bonds in tax-deferred accounts like IRAs.
Advantages of Discount Bonds
The main advantage is capital appreciation potential. If interest rates fall, discount bonds typically rise in price faster than premium bonds (due to higher "convexity" and duration). They also allow investors to lock in a known return. With a zero-coupon bond, you know exactly what you will receive at maturity, eliminating "reinvestment risk" (the risk that you won't be able to reinvest coupon payments at a good rate).
Disadvantages of Discount Bonds
The primary disadvantage is higher volatility. Discount bonds (especially zeroes) are more sensitive to changes in interest rates than high-coupon bonds. If rates spike, the price of a discount bond will crash harder. Additionally, the "phantom income" tax issue mentioned above can create cash flow problems for taxable investors.
Real-World Example: Buying a "Used" Bond
In 2020, Ford issues a 10-year bond paying 3% interest. The face value is $1,000. In 2024, interest rates have risen to 6%. Investors can now buy new Ford bonds paying 6%.
Common Beginner Mistakes
Avoid these bond pitfalls:
- Thinking "Discount" means "Cheap": Just because a bond is under $1,000 doesn't mean it's a bargain. It might be priced correctly for the current rate environment, or the company might be going bankrupt.
- Ignoring the "Phantom Tax": Buying a Zero in a taxable account and being surprised by a tax bill on income you didn't receive.
- Confusing Yield with Coupon: A discount bond has a low coupon but a high yield. Focus on Yield to Maturity (YTM) for the true return.
FAQs
Sellers don't have a choice. If they need to sell a bond before maturity and interest rates have gone up, the market dictates that the price must come down. If they refuse to sell at a discount, no one will buy it.
It depends on why it is a discount. If it is a discount because interest rates rose (market risk), it is safe if you hold to maturity. If it is a discount because the company is failing (credit risk), it is very risky because you might not get the $1,000 back.
Assuming the issuer doesn't default, you receive the full face value (usually $1,000). The temporary drop in price you saw on your statement doesn't affect the final payout.
A bond is considered a "deep discount" bond if it is selling for significantly less than par, typically 20% or more below face value. Zero-coupon bonds are the most common example.
Not necessarily. They are just different mathematical structures. A premium bond pays you more cash flow now (higher coupons) but you lose principal value at the end. A discount bond pays less now but gives you a bonus at the end. In an efficient market, their total returns (YTM) should be similar for the same risk.
The Bottom Line
Discount bonds offer a way for investors to capture capital appreciation in the fixed-income market. Whether created by market mechanics (rising rates) or design (zero-coupon bonds), they are a fundamental part of the bond ecosystem. Investors looking for reliable long-term growth or specific future payouts often turn to discount bonds. A discount bond is the practice of trading debt below its redemption value. Through the pull-to-par effect, discount bonds may result in predictable capital gains at maturity. On the other hand, they come with higher volatility and complex tax rules. Understanding the relationship between price and yield is the key to mastering discount bond investing.
