FRM問題-你問我答(二十二)


以下這道題是Handbook第五版的題目,可是我看了解答後卻實在不了解,可以麻煩老師幫忙解釋一下嗎?謝謝

P.197

example8.2

ABC, Inc., entered a forward rate agreement(FRA) to receive a rate of 3.75% with a continuous compounding on a principal of USD 1 million between the end of year 1 and the end of year 2.The zero rates are 3.25% and 3.5% for one and two years. What is the value of the FRA when the deal is just entered?

 

答覆:

ABC, Inc., 簽訂一個遠期利率契約,在第一年年底與第二年年底之間收本金USD1百萬3.75%利率,連續複利,一年期與二年期零息債券利率是3.25%3.50%。該筆交易在簽訂時的價值為多少?

a. USD 35,629

b. USD 34,965

c. USD 664

d. USD 0

解答:d

 

市場隱含一年後到第二年年底之間的一期遠期利率F(下標1,2)可由下列公式求出:

exp-R(下標2)×2=exp-R(下標1)×1- F(下標1,2)×1

F(下標1,2)=2×3.50-1×3.25=3.75%

由於F(下標1,2)等於該遠期利率契約的報價,因此該筆交易的價值為0

 

假設該筆交易的報價利率為3.50%,則

該筆交易的價值為:

V=$1,000,000×exp3.75%-3.50%-1exp-3.50%×2=2,334
