Explanation:

Interest rate parity (IRP) is a theory which suggests that the rates of return on comparable assets in two different countries are equal, meaning it is a no-arbitrage condition where investors are at a equilibrium state by being less-concerned about the interest rates by banks in two different countries.

Basically, Interest rate parity gives the relationship between spot exchange, interest and foreign exchange rates.
