Bond Prices and Yields
Prices and Yields (required rates of
return) have an inverse
relationship
• When yields get very high the
value of the bond will be very low
• When yields approach zero, the
value of the bond approaches the
sum of the cash flows

Yield to Maturity
YTM = the discount rate that makes the present
value of the bond’s promised payments equal
to its price.
Bond is priced at $1067.95, it has a coupon rate
of 9% paid semiannually, a par value of $1000,
and 10 years to maturity. Find the bond’s ytm.
What is the current yield?
Bond is priced at $945.40 , it has a coupon rate
of 6% paid semiannually, a par value of $1000,
and 14 years to maturity. Find the bond’s ytm.
What is the current yield?

YTM versus current yield
versus coupon rate
• Bond selling at par
– coupon = YTM = current yield
• Bond selling at a premium
– coupon > current > YTM
• Bond selling at a discount
– coupon < current < YTM

Yield to call (YTC)
• Similar to YTM, but use time to first
call date and call price as future
value.
• Bond with 15 years to maturity, par
of $1000, a coupon rate of 8% (paid
semiannually), price of $1025,
callable in 5 years at $1080. Find
YTC.

Realized compound yield
versus yield to maturity
• YTM will equal the realized return
over the life of the bond if all
payments are reinvested at an
interest rate equal to the bond’s
yield.
– Consider a bond with 10 years to
maturity, coupon rate of 9 percent
paid annually, and a price of
$1067.10.

Realized compound yield (RCY)
versus yield to maturity (YTM)
• Consider a bond with 10 years to maturity,
coupon rate of 9 percent paid annually,
and a price of $1067.10.
– What is its ytm?
– Realized compound yield if you
reinvest at ytm?
– RCY if you reinvest at 3 percent?

Holding period return (HPR)
versus YTM.
• Consider a bond with 10 years to maturity,
•
•
coupon rate of 9 percent paid annually,
and a price of $1067.10. Note: ytm = 8%
Suppose you hold the bond one year and
interest rates decline to 7 percent.
Calculate your HPR.
Suppose instead that rates had risen to 9
percent. What is your HPR?

Original Issue Discount (OID)
• Consider a 10 year Treasury strip with a
yield of 5 percent and face of $10,000.
– Price = $6,139.13
– After one year (yield = 5%)
»P = $6,446.09
»Difference = implicit interest = $306.96
»If you sold the strip for $6,500, then
you would have interest income of
$306.96 and capital gain of $53.91

Term Structure of Interest Rates
• Relationship between yields to maturity
•
and maturity
Yield curve - a graph of the yields on
bonds relative to the number of years
to maturity
– Usually Treasury Bonds
– Have to be similar risk or other
factors would be influencing yields
