Ch 8 - Interest Rates and Bond Valuation
Maturity
the number of years until the face value is paid
Dirty price
the price you actually pay, including accrued interest
Clean price
the quoted price on a bond
Interest Rate Risk
the risk that arises for bond owners from fluctuating interest rates you should keep the following in mind when looking at a bond: 1. All other things being equal, the longer the time to maturity, the greater the interest rate risk 2. All other things being equal, the lower the coupon rate, the greater the interest rate risk
Coupons
the stated interest payment on a debt instrument sometimes called a level coupon bond if it is consistent and paid every year
How to calculate rates
1 + R = (1 + r) x (1 + h) where R = nominal rate, r = real rate, h = inflation
Fisher effect
A rise in the rate of inflation causes the nominal rate to rise just enough so that the real rate of interest is unaffected. In other words, the real rate is invariant to the rate of inflation.
Determinants of bond yields
Interest rate risk premium, inflation premium, real rate, nominal interest rate, time to maturity
How are bonds bought and sold?
Most trading in bonds take place over the counter or OTC
A bond has a quoted price of $1,080.42. It has a face value of $1,000, a semiannual coupon of $30, and a maturity of five years. What is its current yield? What is its yield to maturity? Which is bigger? Why?
Notice that this bond makes semiannual payments of $30, so the annual payment is $60. The current yield is thus $60/1,080.42 = 5.55 percent. Now, in this case, the bond pays $30 every six months and it has 10 six-month periods until maturity. So, we need to find r as follows: $1,080.42 = $30 × [1 − 1/(1 + r)^10]/r + 1,000/(1 + r)^10 r = 2.1% per 6 months, so YTM is 4.2%
Inflation risk
Risk faced by Investors due to uncertainty about future inflation.
Coupon rate
The annual coupon a bond pays divided by its face value
Yield to Maturity
The interest rate required in the market on a bond It is the discount rate that equates the present value of the interest payments and redemption value of a bond with the present price of a bond.
Par Value
The nominal or face value of stocks or bonds. For stock, it is a relatively unimportant value except for bookkeeping purposes.
Nominal rate
The percentage change in the number of dollars you have.
Real Rate
The real rate on an investment is the percentage change in how much you can buy with your dollars. In other words, the real rate is the percentage change in your buying power.
Face Value
The value of a bond that appears on its face. Also referred to as par value or principal.
Current yield
a bond's annual coupon divided by its current market
Bond
debt securities - normally an interest-only loan, meaning the borrower will pay the interest every period, but none of the principal will be repaid until the end of the loan
