& 25 1. Bond Yields. A 30-year Treasury bond is issued with face value of $1‚000‚ paying interest of $60 per year. If market yields increase shortly after the T-bond is issued‚ what happens to the bond’s a. coupon rate? The fixed rate is 6% and will not change the $60 per year. b. price? Price is dependent upon the market interest rate. If the market interest rate goes up‚ the bond price goes down; if the interest rate goes down‚ the price of the bond must increase. c. yield to maturity?
