## What is the ‘Uncovered Interest Rate Parity – UIP’

The uncovered interest rate parity (UIP) is a parity condition stating that the difference in interest rates between two countries is equal to the expected change in exchange rates between the countries’ currencies. If this parity does not exist, there is an opportunity to make a risk-free profit using arbitrage techniques.

## Explaining ‘Uncovered Interest Rate Parity – UIP’

Assuming foreign exchange equilibrium, interest rate parity implies that the expected return of a domestic asset will equal the expected return of a foreign asset once adjusted for exchange rates. There are two types of interest rate parity: covered interest rate parity and uncovered interest rate parity. When this no-arbitrage condition exists without the use of forward contracts, which are used to hedge foreign currency risk, it is called uncovered interest rate parity.
