(Q. 1 in B) The above are the key rate durations for three portfolios of Treasury securities. One of these three portfolios is of ladder type; one is of barbell type; and another one is of bullet type. Consider the following nonparallel shift in the Treasury yield curve: the 5-year rate decreases by 35 basis points (bps), the 15- year rate increases by 20 bps, and the 25-year rate decreases by 40 bps. The rates for all other key maturities experience no change. What is the approximate change in the portfolio value for the ladder type portfolio? A) A 0.27% decrease. B) A 0.27% increase. C) A 0.28% decrease. D) A 0.28% increase. E) A 0.29% increase. Answer D Portfolio I is of the barbell type; portfolio II is of the bullet type; and portfolio III is of the ladder type. For portfolio III, the approximate change in the portfolio value = [-(0.60 × (-0.35%))] + [-(0.72 × (0.20%))] + [-(0.53 × (-0.40%))] = 0.28% increase. 1
