Understanding Forward Exchange Rates
A forward exchange rate is the exchange rate agreed upon today for a currency transaction that will occur at a future date. Forward rates are determined by the covered interest rate parity principle, which states that the forward rate should eliminate arbitrage opportunities between spot and forward markets.
Covered Interest Rate Parity Formula
Forward Rate Calculation
- F = S × (1 + r_domestic × t/360) / (1 + r_foreign × t/360)
- F = Forward exchange rate
- S = Spot exchange rate
- r_domestic = Domestic interest rate
- r_foreign = Foreign interest rate
- t = Time period in days
Simplified Approximation
- F ˜ S × [1 + (r_domestic - r_foreign) × t/360]
- Approximation for small interest rate differentials
- Forward premium/discount ˜ (r_domestic - r_foreign) × t/360
- Useful for quick calculations
Interest Rate Parity Theory
The Foundation of Forward Rates
Why forward rates are determined by interest rates
Arbitrage Elimination
- Prevents risk-free profit opportunities
- Equalizes returns across currencies
- Links spot and forward markets
- Enforces market efficiency
Interest Rate Relationship
- Higher interest rate currency trades at forward discount
- Lower interest rate currency trades at forward premium
- Reflects borrowing and lending costs
- Determines currency expectations
Forward Rate Interpretation
| Interest Rate Comparison | Forward Rate vs Spot Rate | Market Implication | Currency Expectation |
|---|---|---|---|
| r_domestic > r_foreign | Forward < Spot | Forward Discount | Domestic currency expected to depreciate |
| r_domestic < r_foreign | Forward > Spot | Forward Premium | Domestic currency expected to appreciate |
| r_domestic = r_foreign | Forward = Spot | No Premium/Discount | No expected currency movement |
