Suppose Scarlett purchased a 3-year bond with the face value of 20,000 in the primary market. The current risk-free interest rate was 0.5%, and a risk premium on that bond is 3%. A year later after collecting her yearly coupon payment, Scarlett decided to sell that bond in the secondary market. By that time, the economic situation has improved, and the risk-free interest rate has risen to 1%. What is Scarlett's rate of return for the one-year period she held the bond?
