Uncovered interest rate parity [UIRP]

PrepNuggets

LEVEL II

Uncovered Interest Rate Parity (UIRP) states that the difference between two countries’ interest rates should be equal to the expected change in the exchange rate between the two currencies. In other words, UIRP states that an investor should receive the same return, after adjusting for expected exchange rate changes, regardless of whether they invest in a low-interest rate country or a high-interest rate country. The “uncovered” part of the name refers to the fact that this principle does not take into account the use of financial instruments such as forward contracts to hedge against exchange rate risk, hence the investment is “uncovered” to exchange rate risk. UIRP is based on the assumption that investors are risk neutral.
