Libor interest rates for the British pound: 1.6025%
Libor interest rates for the New Zealand dollar: 3.2875%
All Libor interest rates are quoted on a 360-day year basis
The 180-day forward points (scaled up by four decimal places) in NZD/GBP is closest to:
选项:
A.39
B.348
C.176

Solution
C is correct. Covered interest arbitrage will ensure identical terminal values by investing the same initial amounts at the respective country’s domestic interest rates:
GBP investment: ₤1 × (1 + 0.016025 × 180/360) = ₤1.008013
NZD investment: NZ$2.0979 × (1 + 0.032875 × 180/360) = NZ$2.13238
The forward rate is determined by equating these two terminal amounts:
NZD/GBP forward rate = NZ$2.13238/₤1.008013 = 2.115429
Forward points = (Forward – Spot) × 10,000
= (2.1155– 2.0979) × 10,000
= 175.3 =176 (rounded)
A is incorrect. It inverts the currencies.
GBP investment: ₤2.0979 × (1 + 0.016025 × 180/360) = ₤2.1147
NZD investment: NZ$1 × (1 + 0.032875 × 180/360) = NZ$1.0164
The forward rate is determined by equating these two terminal amounts:
NZD/GBP forward rate = NZ$1.0164/₤2.1147 = 0.4806
Inverted Spot: 1/2.0979 = 0.47667
Forward points = (Forward – Spot) × 10,000
= (0.4806– 0.4767) × 10,000
= 39
B is incorrect. It ignores the half-year time frame of the contract:
GBP investment: ₤1 × (1 + 0.016025) = ₤1.016025
NZD investment: NZ$2.0979 × (1 + 0.032875) = NZ$2.16687
NZD/GBP forward rate = NZ$2.16687/₤1.016025 = 2.1327
Forward points = (Forward – Spot) × 10,000
= (2.1327 – 2.0979) × 10,000
= 347.9
中文解析:
C正确。备兑利息套利将通过按各自国家的国内利率投资相同的初始金额来确保相同的终端价值:
英镑投资:1英镑× (1 + 0.016025 × 180/360) = 1.008013英镑
纽元投资:NZ$2.0979 × (1 + 0.032875 × 180/360) = NZ$2.13238
远期汇率是通过将这两个终端金额相等来确定的:
纽元兑英镑远期汇率= 2.13238纽元兑1.008013英镑= 2.115429
远期点=(远期点)× 10000
= (2.1155 - 2.0979) × 10000
= 175.3 =176(四舍五入)
A不正确。它颠倒了货币。
英镑投资:£2.0979 × (1 + 0.016025 × 180/360) =£2.1147
新西兰元投资:新西兰元1 × (1 + 0.032875 × 180/360) =新西兰元1.0164
远期汇率是通过将这两个终端金额相等来确定的:
纽元兑英镑远期汇率=纽元兑1.0164英镑兑2.1147英镑= 0.4806
倒挂即期汇率:1/2.0979 = 0.47667
远期点=(远期点)× 10000
= (0.4806 - 0.4767) × 10000
= 39
B不正确。它忽略了合同的半年时间框架:
英镑投资:1英镑×(1 + 0.016025) = 1.016025英镑
纽元投资:NZ$2.0979 × (1 + 0.032875) = NZ$2.16687
纽元兑英镑远期汇率= 2.16687纽元兑1.016025英镑= 2.1327
远期点=(远期点)× 10000
= (2.1327 - 2.0979) × 10,000
= 347.9
该道题用利率平价公式算的话,2.9079NZD/GBP应该乘以本国投资(1+1.6025%/2)再除以外国投资(1+3.2875%/2)呀,为什么答案里是反的呢?麻烦求解~
