Definition
Covered Interest Rate Parity (CIP) is a theoretical framework which posits that the difference in interest rates between two countries is equal to the differential in their forward and spot exchange rates. Essentially, it illustrates how currencies’ spot values and interest rates must align to prevent arbitrage opportunities, thus ensuring that expected returns are equal across borders when forward contracts are utilized.
Covered Interest Rate Parity (CIP) vs Uncovered Interest Rate Parity (UIP)
| Criterion | Covered Interest Rate Parity (CIP) | Uncovered Interest Rate Parity (UIP) |
|---|---|---|
| Arbitrage Opportunity | No arbitrage opportunity | Possible arbitrage opportunity |
| Forward Contracts | Utilizes forward contracts | Does not utilize forward contracts |
| Risk Exposure | Less risk due to guaranteed rates | Greater risk due to expected future rates |
| Interest Rates Impact | Interest rates influence forward rates | Interest rates influence future spot rates |
| Example Currency Pair | USD/EUR with forward contracts | USD/JPY without forward contracts |
Formula for Covered Interest Rate Parity
To express Covered Interest Rate Parity mathematically, we can use the following equation:
\[ 1 + i_d = \frac{F}{S} (1 + i_f) \]
Where:
- \( i_d \) = interest rate of the domestic currency
- \( i_f \) = interest rate of the foreign currency
- \( F \) = forward exchange rate
- \( S \) = spot exchange rate
Example
Suppose:
- The domestic interest rate (\(i_d\)) is 2%
- The foreign interest rate (\(i_f\)) is 5%
- The spot exchange rate (\(S\)) between USD and EUR is 1.2
- The forward rate (\(F\)) for a one-year contract is quoted at 1.25
Using the CIP formula: \[ 1 + 0.02 = \frac{1.25}{1.2} (1 + 0.05) \]
Calculating the right-hand side: \[ 1.02 = \frac{1.25}{1.2} \cdot 1.05 \approx 1.09375 \] Thus, CIP does not hold, indicating an arbitrage opportunity exists!
Related Terms
- Uncovered Interest Rate Parity (UIP): Similar to CIP but does not involve forward contracts and is subject to exchange rate risk.
- Arbitrage: The practice of taking advantage of price differences in different markets to earn risk-free profits.
- Forward Contract: A financial agreement to buy/sell an asset at a specified future date for an agreed-upon price.

Fun Fact
Did you know? The concept of arbitrage dates back to the early 18th century, and it was named after a French merchant whose last name was “Ridge,” which sounds much cooler than “arbitrage,” don’t you think?
FAQs
Q1: How does Covered Interest Rate Parity prevent arbitrage?
A1: CIP ensures that the difference in returns on equivalent investments in different currencies is null, making it unattractive to exploit price differences.
Q2: What happens if CIP does not hold?
A2: If CIP does not hold, it indicates a potential arbitrage opportunity wherein investors may earn risk-free profits by borrowing in one currency and investing in another.
Q3: Can geopolitical events affect CIP?
A3: Absolutely! Geopolitical events can lead to unexpected changes in interest rates and currency fluctuations, potentially breaking the equilibrium that CIP represents.
