(b) Design an arbitrage trading strategy such that an arbitrage profit can be (10 marks) made if the deposit rate of 1-year GBP deposit is 10%. You may use 1 million USD as a base case to illustrate you answer and calculation. Assume you can deposit and borrow with the same rate as indicated for each currency. (4% for USD and 10% for GBP).
