INTERNATIONAL FISHER EFFECT - IFE

An economic theory which states an expected change in the present exchange rate between any two currencies is roughly equivalent to the difference between two nations’ nominal interest rates at a given time. Named after American economist Irving Fisher, the higher the inflation rate, the lower the value of currency. Computed as:

E = 11 - 12 / 1 + 12 = 11 - 12

Where

E - % change in the exchange rate

11 - country A’s interest rate

12 - country B’s interest rate
