or a 20-year, $1,000 par value, 6 percent coupon T-bond yielding 5 percent, the dollar value of a basis point (DV01) and associated percentage price change (PPC) are closest to:

A) $0.14 and 0.01%.
B) $0.57 and 0.06%.
C) $2.45 and 0.20%.
D) $1.37 and 0.12%.
View Answer and Explanation
N=20×2; I/Y=5/2; PMT=60/2; FV=1000; CPT→PV=1,125.51=V0
N=20×2; I/Y=4.99/2; PMT=60/2; FV=1000; CPT→PV=1,126.88=V-
DV01=1,126.88-1,125.51=$1.37. PPC=DV01/V0=1.37/1,125.51=0.0012.

Hi anbu
Both are one and the same. For small changes (1 basis point in this case), the bond price changes proportional to the change in the yield (Remember the duration effect?). So if it were 5.01, the bond price would have decreased by 1.37 approximately.
