Fisher Formula: Is only relation between nominal and real interest rate that simple?

Fisher formula shows the simple relationship between nominal and real interest rate. The gap between them is inflation rate. However, this formula indicates the impact on foreign exchange rate. We are here to explain.



i = nominal interest rate

r = real interest rate

h = inflation rate

A: The Fisher Formula is relevant under risk management.

Q: What is The Fisher Formula?

A: The nominal interest rate is made up of two parts: the real interest rate plus a premium for inflation.

Q: What does The Fisher Formula imply?
