Definition of Interest Rate Parity (IRP)§
Interest Rate Parity (IRP) is a fundamental financial theory that establishes a relationship between interest rates in different countries and the exchange rates of their currencies. The premise of IRP is that in the absence of arbitrage opportunities, the return on domestic investments should equal the return on foreign investments after considering exchanged currency rates and the interest rate differentials. In simpler terms: if you could invest in a foreign currency at a higher interest rate but didn’t account for exchange rates, you’d be left with a currency that might make your investment less valuable upon conversion.
| Interest Rate Parity (IRP) | Covered Interest Rate Parity (CIRP) |
|---|---|
| Considers returns in unhedged investments | Considers returns in hedged investments |
| Focuses on open markets without risk-free arbitrage | Involves forward contracts to hedge against exchange rate risk |
| Useful in calculating expected changes in currency values | Useful for finding discrepancies in interest rates across countries |
Examples of Interest Rate Parity§
If the U.S. dollar has an interest rate of 2% and the Euro has an interest rate of 4%, according to IRP, the exchange rates should adjust such that the returns from investing in both currencies would ultimately yield the same returns when hedged for risks.
