Question
A forex expert notices the following rates:
A riskless arbitrage profit exists that is closest to:
选项:
A.0.49%. B.1.04%. C.0.46%.解释:
Solution
- The expert can secure a riskless arbitrage gain of 0.49%, determined as:
Return on the hedged foreign investment: Sf/d(1 + if)[1/Ff/d]-1 = 1.68(1.055)[1/1.72]-1 = 1.0246 -1= 3.05%.
Riskless arbitrage profit = Domestic risk-free rate – Return on the hedged foreign investment: 3.54% – 3.05% = 0.49%.
• explain the arbitrage relationship between spot and forward exchange rates and interest rates, calculate a forward rate using points or in percentage terms, and interpret a forward discount or premium
专家可以获得0.49%的无风险套利收益,过程如下:
套期保值的境外投资回报率:Sf/d(1 + if)[1/Ff/d]-1 = 1.68(1.055)[1/1.72]-1 = 1.0246 -1= 3.05%。
无风险套利利润=境内无风险利率-套期境外投资回报率:3.54% - 3.05% = 0.49%。
老师上课讲可以用f/s(1+f外)-(1+f本)=1.72/1.68*(1+5.50%)-(1+3.54%)=0.044719。请问是哪里出错了
