What does covered interest rate parity relate to?

• A. The relationship between short-term interest rates and commodity prices
• B. The relationship between spot and forward exchange rates and interest rates
• C. The relationship between long and short positions in a currency
• D. The relationship between noise traders and market performance

Answer: (B)

Covered interest rate parity is a fundamental principle in international finance that establishes a relationship between spot and forward exchange rates and interest rates. This concept asserts that the difference between the interest rates of two countries is equal to the differential between the forward exchange rate and the spot exchange rate.

When investors seek to exploit interest rate differentials between two currencies, covered interest rate parity ensures that there are no arbitrage opportunities available. This means that if one currency offers a higher interest rate, any potential profit from this higher rate would be offset by the forward exchange rate adjustments that account for the interest rate difference, effectively neutralizing the advantage.

Thus, the relationship outlined in the answer captures the essence of how forward and spot exchange rates are influenced by the interest rates of the countries involved, ensuring that capital flows align with the expectations of future exchange rates, thereby maintaining market equilibrium.
