Suppose that you invest in a two-year Treasury bond with a coupon rate of 8% and $1,000 par. Suppose that you buy this bond at a price of exactly $1,000. You intend to hold this bond to maturity and reinvest the coupons until the bond matures. You expect to reinvest the coupons in an account that pays an APR of 2.64%, with semi-annual compounding. What is the effective annual rate of return on your investment?
