Calculate covered and uncovered interest arbitrage opportunities between currencies
About this calculator
The Currency Interest Rate Arbitrage Calculator helps traders and investors identify profitable arbitrage opportunities between different currencies by analyzing interest rate differentials. It calculates both covered arbitrage (using forward contracts to eliminate exchange rate risk) and uncovered arbitrage (accepting currency risk for potentially higher returns). This tool is essential for forex traders, institutional investors, and financial analysts seeking to capitalize on interest rate disparities across international markets while understanding the associated risks and potential profits from currency arbitrage strategies.
How to use
Enter the domestic and foreign interest rates, current spot exchange rate, and investment amount. For covered arbitrage, input the forward exchange rate. Select your calculation period and choose between covered or uncovered arbitrage. The calculator will display potential profit, return percentage, and risk assessment to help you evaluate the arbitrage opportunity.
