Kingdom is 1.4339 GBP/USD. Also suppose the current interest rates are 5 percent in the U.S. and 7 percent in the U.K. What is the expected spot exchange rate 12 months from now according to the international Fisher effect? The effect estimates future exchange

The expected percentage change in the exchange rate is a depreciation of 1.87% for the GBP (it now only costs $ 1.4071 to purchase 1 GBP rather than $ 1.4339), which is consistent with the expectation that the value of the currency in the country with a higher interest rate will depreciate.
