A bond is simply a negotiable IOU, or a loan. Investors who buy bonds are lending a specific sum of money to a corporation, government, or some other borrowing institution. Bonds are often referred to as fixed-income investments. Bond Basics
Key Features of a Bond • Debt instrument issued by a corp. or government.
Key Features of a Bond • Par value = face amount of the bond, which is paid at maturity (assume $1,000). =
Key Features of a Bond • Coupon rate – stated interest rate (generally fixed) paid by the issuer. Multiply by par to get dollar payment of interest.
Key Features of a Bond • Maturity date – when the bond must be repaid. • Yield to maturity - rate of return earned on a bond held until maturity.
What is reinvestment rate risk? • Reinvestment rate risk is the concern that interest rates will fall, and future money will have to be reinvested at lower rates, hence reducing income.
What is interest rate risk? • Interest rate risk is the concern that interest rates will rise, and therefore, a reduction in the value of a security.
Reinvestment rate risk example Suppose you just inherited $500,000. You intend to invest the money and live off the interest.
Reinvestment rate risk example • You may invest in either a 10-year bond or a series of ten 1-year bonds. • Both bonds currently yield 5%.
If you choose the 1-year bond strategy: • After Year 1, you receive $25,000 in income and have $500,000 to reinvest. But, if 1-year rates fall to 3%, your annual income would fall to $15,000. • If you choose the 10-year bond strategy: • You can lock in a 5% interest rate, and $25,000 annual income.
Long-term bonds: High interest rate risk, low reinvestment rate risk. • Short-term bonds: Low interest rate risk, high reinvestment rate risk.

Most Bonds Pay Interest Semi-Annually: What is the value of a bond with a semi-annual coupon with 5 years to maturity, 9% (nominal) coupon rate if an investor desires a 10% (nominal) return?

Types of Bonds • Vanilla – fixed coupons, repaid at maturity • Convertible – can be converted into to stock • Zero Coupon – pay no explicit interest but instead, sell at a deep discount
Types of Bonds • Junk Bonds – below investment grade
AAA Best Quality AA High Quality A Upper Medium Grade BBB Medium Grade BB Speculative B Very Speculative CCC Very Very Speculative CC C No Interest Being Paid D Currently in Default Bond Ratings • Moody’s and Standard & Poor’s regularly monitor issuer’s financial condition and assign a rating to the debt Investment Grade Below Investment Grade (Junk)
What affects Bond prices? • Risk • Interest rates
What is the “term structure of interest rates”? What is a “yield curve”? • Term structure: the relationship between interest rates (or yields) and maturities. • A graph of the term structure is called the yield curve.
Hypothetical Treasury Yield Curve Interest Rate (%) 1 yr 8.0% 10 yr 11.4% 20 yr 12.65% 15 Maturity risk premium 10 Inflation premium 5 Real risk-free rate Years to Maturity 0 1 20 10
Current Rates • Bloomberg
What factors can explain the shape of this yield curve? • This constructed yield curve is upward sloping. • This is due to increasing expected inflation and an increasing maturity risk premium.
Default risk • If an issuer defaults, investors receive less than the promised return. • Influenced by the issuer’s financial strength and the terms of the bond contract.
