问题如下:
The discount rate of a 180-day banker’s acceptance for a 360-day year quoted at a bond equivalent yield of 6.72% is closest to:
选项:
A.6.62%
B.6.51%
C.6.42%
解释:
C is correct.
Bond equivalent yield (BEY) for money market security is yield stated on a 365-day add-on rate basis.
PV=96.79
PV=100*[1-(180/360)*discount rate]=96.79
discount rate=0.0642
考点:BEY
解析:本题考点是discount yield和BEY之间的转换。我们通过BEY反求出PV,即PV=96.79。注意BEY中的year要代入365,因为BEY是365天的AOR。
有了FV和PV再代入上述第二个公式从而算得discount yield,即discount rate=0.0642。注意,discount yield中Year应该代入题目已知条件360。
在第一步计算出了pv = 96.79后,应该可以从等式 FV = PV * (1+ discount rate * 180/360),并带入FV = 100, PV = 96.79, 得出 discount rate = 6.6329%。 是吗?
