- involves the potential for bond prices to change due to fluctuations in market interest rates
- Bond prices and market interest rates have an inverse relationship
- Rising market interest rates cause bond prices to decline
- Falling market interest rates lead to an increase in bond prices
- The illustrates the relationship between interest rates and bond maturities
- Bond prices and market interest rates have an inverse relationship
- Default risk, also referred to as , is the possibility that a bond issuer may not fulfill their obligation to make scheduled interest or principal payments
- Failure to meet these payments results in a default on the bond
Duration for interest rate risk
- quantifies a bond's sensitivity to changes in market interest rates and is expressed in years
- Represents the weighted average time required to receive a bond's cash flows
- is calculated using the formula:
- denotes the cash flow received at time
- represents the yield to maturity
- is the number of periods until the bond matures
- is derived from Macaulay duration using the formula:
- Measures the percentage change in a bond's price given a 1% change in yield
- Bonds with longer durations exhibit greater sensitivity to interest rate changes and thus carry higher
- measures the rate of change in a bond's duration as interest rates fluctuate
Factors in bond default risk
- Issuer's assesses their financial stability and ability to generate sufficient cash flows to service their debt obligations
- Bond's determines the priority of repayment in the event of default, with senior debt taking precedence over subordinated debt
- backing a bond can reduce default risk, as secured bonds are backed by specific assets, while unsecured bonds lack this protection
- impose restrictions on the issuer's activities to safeguard the interests of bondholders
- Macroeconomic conditions, such as economic recessions, can increase default risk across all bond issuers
Bond laddering strategy
- is a strategy that involves constructing a portfolio of bonds with varying maturities
- Helps to diversify interest rate risk by allocating investments across different maturity dates
- As shorter-term bonds mature, the proceeds are reinvested in longer-term bonds
- Provides a consistent stream of cash flows and mitigates the impact of interest rate fluctuations on the overall portfolio
Credit ratings for default risk
- Credit rating agencies, such as Moody's, Standard & Poor's, and Fitch, evaluate the creditworthiness of bond issuers
- Ratings span from AAA (highest quality) to C or D (default)
- Investment-grade bonds are rated BBB (S&P) or Baa (Moody's) and above
- High-yield or "junk" bonds are rated below BBB (S&P) or Baa (Moody's)
- Lower credit ratings signify higher default risk and generally offer higher yields to compensate investors for the increased risk
Yield to maturity calculation
- represents the total return earned by holding a bond until it matures
- Assumes all cash flows are reinvested at the same rate as the YTM
- YTM is calculated using the bond's current market price, face value, coupon rate, and remaining time to maturity
- YTM is the discount rate that equates the present value of a bond's future cash flows to its current market price
- The formula for calculating YTM is:
- YTM is determined through trial and error or by using a financial calculator
- A higher YTM indicates a higher expected return and typically implies higher risk associated with the bond
Additional Bond Risks
- : The potential difficulty in selling a bond quickly without incurring significant losses
- : The possibility that future cash flows from a bond will be reinvested at a lower interest rate
- : The risk that an issuer will redeem a callable bond before its maturity date, potentially forcing investors to reinvest at lower rates
- : The potential for the purchasing power of bond interest payments and principal to decrease due to rising inflation
Key Terms to Review (42)
Bond call: A bond call is a feature that allows the issuer to repay and retire its bonds before the maturity date. This is often done when interest rates decline, enabling the issuer to refinance at a lower cost.
Bond Covenants: Bond covenants are legally binding restrictions or requirements placed on a bond issuer by the bond holder. They are designed to protect the bond holder's interests and ensure the issuer maintains a certain level of financial health and operations to meet their debt obligations.
Bond laddering: Bond laddering is an investment strategy that involves purchasing bonds with different maturity dates to spread out interest rate risk and reinvestment opportunities. It aims to provide a steady stream of income and reduce the impact of fluctuating interest rates.
Bond Laddering: Bond laddering is an investment strategy that involves building a portfolio of bonds with staggered maturity dates. This approach aims to manage interest rate risk and provide a steady stream of income over time by creating a diversified bond portfolio that matures at regular intervals.

Call risk: Call risk is the risk that a bond may be redeemed by the issuer before its maturity date, typically when interest rates fall. This results in the bondholder receiving their principal back earlier than expected and potentially reinvesting at lower interest rates.
Call Risk: Call risk refers to the risk that a bond issuer will redeem or 'call' a bond before its maturity date, forcing the bondholder to reinvest the principal at potentially less favorable interest rates. This risk is particularly relevant in the context of interest rate and default risks, as changes in market conditions can trigger a bond call.
