Practical Example
Suppose you want to analyze the interest parity between USD and EUR:
- Domestic Interest Rate (USD): 2%
- Foreign Interest Rate (EUR): 1%
- Spot Rate (USD/EUR): 1.10
- Forward Rate (USD/EUR): 1.12
Calculation: Forward Rate=Spot Rate×1+Domestic Rate1+Foreign Rate\text{Forward Rate} = \text{Spot Rate} × \frac{1 + \text{Domestic Rate}}{1 + \text{Foreign Rate}}Forward Rate=Spot Rate×1+Foreign Rate1+Domestic Rate Forward Rate=1.10×1+0.021+0.01≈1.111\text{Forward Rate} = 1.10 × \frac{1 + 0.02}{1 + 0.01} ≈ 1.111Forward Rate=1.10×1+0.011+0.02≈1.111
Result: The theoretical forward rate is 1.111, indicating a slight deviation from the actual forward rate (1.12), which may represent a potential arbitrage opportunity.
