Treasury Bonds

Price vs. Yield to Maturity

The price of a fixed rate security depends on the relationship between its yield to maturity and the interest rate. If the yield to maturity (YTM) is greater than the interest rate, the price will be less than par value; if the YTM is equal to the interest rate, the price will be equal to par; if the YTM is less than the interest rate, the price will be greater than par. See an example of price vs. yield to maturity.

When purchasing a Treasury bond, any interest accrued since the last interest payment is added to the bond purchase price. At the next interest payment date the investor receives the full interest payment.

Use the following formula to figure accrued interest:

A = P x r ( d / t )/2 A = Accrued interest
P = Face value
r = interest rate of Treasury bond
d = # of days since last coupon payment
t = # of days in current coupon period

Example: A 5% 30-year bond ($1,000 principal) is purchased 91 days after the last coupon payment. The current coupon period contains 182 days.

A = 1000 x .05 (91/182)/2 , solving

A = $12.50
