A bond market analyst forecasts that in five years, 25-year maturity bonds will sell at yields to maturity of 7% and that 15-year maturity bonds will sell at yields of 6.5%. Because the yield curve is upward-sloping, the analyst believes that coupons will be invested in short-term securities at a rate of 5%.
