Imagine you stumble upon a bond trading far below its face value. This isn’t just any bond; it’s deeply discounted, offering the tantalizing prospect of significant returns. But how do you know if this opportunity is real? And how do you determine if the price reflects the bond’s intrinsic value? This article will guide you through valuing a deeply discounted bond, equipping you with the knowledge to make informed investment decisions.
First, let’s define our terms. A deeply discounted bond is simply a bond trading significantly below its face value, often due to factors such as rising interest rates, credit downgrades, or market volatility.
By the end of this article, you’ll understand the key concepts driving discount bond pricing, master the valuation techniques, and be better positioned to capitalize on the potential rewards while navigating the inherent risks.
Understanding the fundamentals
Before we dive into the valuation process, let’s solidify our understanding of some key concepts.
- Face value represents the amount the issuer promises to repay you at the bond’s maturity. It is also known as the bond’s “par value,” typically $1,000.
- Coupon rate determines the annual interest payments you’ll receive. It’s expressed as a percentage of the face value. For instance, a 6% coupon rate on a $1,000 bond translates to $60 in interest paid annually.
- Yield to maturity (YTM) is the total return you anticipate earning on the bond if you hold it until it matures. It considers the coupon payments and any price appreciation or depreciation between the purchase price and the face value. YTM is a crucial factor in determining a bond’s fair value.
- Discount rate reflects the minimum return you, as an investor, require to compensate you for the risks associated with investing in the bond. It’s influenced by prevailing interest rates, inflation expectations, and the issuer’s creditworthiness.
The discount bond phenomenon
Now, let’s connect these concepts. Here’s the crux of the matter. If the coupon rate offered on the bond is lower than the required yield (your discount rate), you won’t pay full price for it.
As stated earlier, if the compensation you receive from the bond’s coupon payments is insufficient to meet your desired return, you’ll only buy the bond at a discount.
Let’s illustrate this with an example: Imagine a bond with a 6% coupon rate. If you, as an investor, require a 7% return (your discount rate), you won’t pay $1,000 for the bond. You’ll only buy it at a price that allows you to achieve your 7% return when you factor in the coupon payments and the eventual repayment of the face value.
Valuation methods
Now that you understand the fundamental concepts let’s explore the practical methods for valuing deeply discounted bonds.
Present value approach
At its core, bond valuation revolves around the concept of present value. You’re essentially determining the current value of the future cash flows the bond will generate. These cash flows include the periodic coupon payments and the final principal repayment at maturity.
| Year | Cash flow (CF) | Discount rate (r) | Time period (t) | Present value factor (1/(1+r)^t) | Present value (PV) |
| 1 | $30 | 3.50% | 1 | 0.966183575 | $28.99 |
| 1 | $30 | 3.50% | 2 | 0.9335107 | $28.01 |
| 2 | $30 | 3.50% | 3 | 0.901942706 | $27.06 |
| 2 | $30 | 3.50% | 4 | 0.871442228 | $26.14 |
| 3 | $30 | 3.50% | 5 | 0.841973167 | $25.26 |
| 4 | $30 | 3.50% | 6 | 0.813500644 | $24.41 |
| 4 | $30 | 3.50% | 7 | 0.785990961 | $23.58 |
| 4 | $30 | 3.50% | 8 | 0.759411556 | $22.78 |
| 5 | $30 | 3.50% | 9 | 0.733730972 | $22.01 |
| 5 | $1,030 | 3.50% | 10 | 0.708918814 | $730.19 |
| Total | $958.42 |
Here’s a step-by-step guide:
1. Determine the periodic coupon payment:
- Identify the coupon rate. In this example, the coupon rate is 6%.
- Calculate the annual coupon payment. Multiply the face value ($1,000) by the coupon rate (6%): $1,000 * 0.06 = $60.
- Determine the periodic coupon payment. Since coupon payments are typically made semi-annually, divide the annual coupon payment by 2: $60 / 2 = $30.
2. Determine the number of periods:
- Identify the bond’s maturity. In this example, the bond matures in 5 years.
- Determine the compounding frequency. Since coupon payments are semi-annual, there are 2 periods per year.
- Calculate the total number of periods. Multiply the number of years to maturity by the number of periods per year: 5 years * 2 periods/year = 10 periods.
3. Calculate the present value of future coupon payments:
- Use the present value formula = Coupon payment / [(1 + Discount rate)^ Number of periods)]
- The formula calculates the present value of a series of equal cash flows (coupon payments) received at regular intervals.
- Year 1 – first half. The $30 coupon payment received one year from now is discounted back to its present value: $30 / (1 + 0.035)^1 = $28.99
- Year 1 – second half. The $30 coupon payment received two years from now is discounted back to its present value: $30 / (1 + 0.035) ^1 = $28.01
- Year 2 – first half. The $30 coupon payment received three years from now is discounted back to its present value: $30 / (1 + 0.035) ^3 = $27.06
- Year 2 – second half. The $30 coupon payment received three years from now is discounted back to its present value: $30 / (1 + 0.035) ^4 = $26.14
4. Calculate the present value of the principal repayment:
- Use the present value of a single sum formula = Face value / (1 + Discount rate)^Number of periods
- Present Value of Principal = $1,000 / (1 + 0.035)^10 = $708.92
5. Sum the present values:
- Add the present value of the coupon payments and the present value of the principal repayment:
- Bond Price = Present Value of coupon payment + Present Value of Principal
- Bond Price = $ 21.27 + $ 708.92
- Bond Price = $730.19
Spreadsheet software (e.g., Excel)
Fortunately, you don’t have to perform these calculations manually. Spreadsheet software like Excel offers built-in functions that can significantly streamline the process.
The PV function in Excel can efficiently calculate the present value of a bond. You’ll need to input the following:
- Rate: Your required yield (discount rate) = 7%/2 = 3.5%
- Nper: The number of periods (e.g., years) until maturity = 5 x 2 = 10
- Pmt: The periodic coupon payment = (6%/2) * $1000 = $30
- FV: The face value of the bond = $1000
- Type: 0 for payments at the end of each period (common for bonds)
- Bond price: = PV(3.5%,10,30,1000) = $958.42

Factors influencing discount bond prices
Several key factors can significantly influence the price of a deeply discounted bond. Understanding these factors is crucial for making informed investment decisions.
Interest rate changes
Bond prices and interest rates share an inverse relationship. When interest rates rise, the attractiveness of existing bonds with lower fixed coupon rates diminishes. To remain competitive, their prices must decline to offer comparable yields to newly issued bonds with higher coupon rates. Conversely, when interest rates fall, the relative attractiveness of existing bonds increases, driving their prices higher.
Rising interest rates can have a particularly significant impact on deeply discounted bonds. Since these bonds offer lower coupon payments, their prices become even more sensitive to interest rate increases. This sensitivity stems from the fact that a larger portion of their return is derived from the price appreciation at maturity, which is directly affected by interest rate movements.
Credit risk
Credit risk refers to the possibility that the bond issuer may default on its obligations, failing to make timely interest or principal payments. Investors demand a higher return (higher yield) to compensate for this increased risk.
Bonds issued by companies or governments with lower credit ratings (higher credit risk) typically trade at lower prices. This lower price reflects the increased risk of default and the higher yield required by investors.
Time to maturity
A bond’s price sensitivity to interest rate changes is influenced by its time to maturity. Longer-term bonds generally exhibit greater price volatility in response to interest rate fluctuations. This is because the present value of distant cash flows is more significantly impacted by changes in the discount rate (which is closely tied to interest rates).
While all bonds are subject to interest rate risk, the impact can be more pronounced for longer-term discount bonds. Due to the longer duration of their cash flows, their prices may experience greater fluctuations in response to interest rate changes.
Inflation expectations
Inflation erodes the purchasing power of money, so investors demand higher yields on their investments to compensate for this impact. Rising inflation expectations typically lead to higher interest rates and, consequently, higher required yields on bonds.
Increased inflation expectations can significantly impact the prices of deeply discounted bonds. As required yields rise to account for inflation, the present value of the bond’s future cash flows declines, pushing its price lower.
Investing in deeply discounted bonds
Now that you understand the characteristics and valuation of deeply discounted bonds let’s explore the potential rewards and risks associated with investing in them.
Potential benefits
Capital appreciation. If interest rates decline, you can potentially realize significant capital appreciation as the prices of your deeply discounted bonds rise. This price appreciation stems from the inverse relationship between interest rates and bond prices.
Enhanced yield potential. Deeply discounted bonds often offer the potential for higher yields compared to other fixed-income securities, particularly those with higher credit ratings. This higher yield compensates investors for the increased risk associated with these bonds.
Risks
Interest rate risk. Rising interest rates pose a significant risk to deeply discounted bonds. As discussed earlier, they can lead to substantial price declines, potentially eroding investment capital.
Credit risk. The risk of issuer default is a crucial consideration. If the issuer of a deeply discounted bond experiences financial difficulties and defaults on its obligations, you may lose a portion or all of your investment.
Liquidity risk. Deeply discounted bonds, particularly those issued by smaller or less well-known issuers, may have lower liquidity than higher-grade bonds. Selling these bonds quickly at a fair price may be more difficult if you need to liquidate your position.
