For example, assume that the interest rate in America is 10% and the interest rate in Canada is 15%. According to the uncovered interest rate parity, the Canadian dollar is expected to depreciate against the American dollar by approximately 5%. Put another way, to convince an investor to invest in Canada when its currency depreciates, the Canadian dollar interest rate would have to be about 5% higher than the American dollar interest rate.
