Utilize our Interest Rate Parity Calculator to understand the relationship between spot and forward exchange rates and interest rates in two countries. This tool helps forex traders and investors identify potential arbitrage opportunities and evaluate currency hedging strategies efficiently.
Formula:
The Interest Rate Parity (IRP) formula is used to determine the theoretical forward exchange rate (F) based on the spot exchange rate (S) and the interest rates of two countries (rd and rf):
F = S × (1 + rd) / (1 + rf)
Where:
- F = Forward Exchange Rate
- S = Spot Exchange Rate (e.g., USD/EUR)
- rd = Domestic Interest Rate (annualized decimal)
- rf = Foreign Interest Rate (annualized decimal)
