Definition
Covered Interest Rate Parity (CIRP) refers to a theoretical financial condition where the interest rate differential between two countries equals the differential between the forward and spot exchange rates of these countries. In other words, it ensures there is no arbitrage opportunity for investors to profit from differences in interest rates offered by two countries and the forward exchange rates. If this parity does not hold, investors could use a strategy called a covered interest arbitrage to earn riskless profit.
Key Takeaways
- Covered Interest Rate Parity (CIRP) is a financial theory that asserts a direct relationship between the spot and forward exchange rates within two countries. It states that the interest rate differential between two countries should be equal to the differential between the forward and spot exchange rates of these countries.
- CIRP is used to prevent arbitrage opportunities. According to this theory, there should be no interest rate advantage when an investor borrows money from a country, converts it in the spot foreign exchange market to another country’s currency, and invests it in the second country. Any potential profit from the interest rate differential will be eliminated by a corresponding change in the forward exchange rate.
- CIRP plays a significant role in currency markets as it helps in pricing foreign exchange forward contracts. It also helps in making funding decisions as it provides insights about whether to borrow domestically or from a foreign country.
Importance
Covered Interest Rate Parity (CIRP) is an important concept in the field of international finance, serving as a fundamental principle for interest rate determination in foreign exchange markets.
It is essential because it assists in maintaining a balance in the foreign exchange market by preventing arbitrage opportunities.
CIRP states that the relationship between interest rates and the spot and forward currency values of two countries should be in equilibrium.
With CIRP, investors cannot generate risk-free profits through currency conversion, investment, and reverse conversion.
Therefore, CIRP ensures market efficiency, influences exchange and interest rates, and is fundamental to understanding and forecasting movements in the foreign exchange market.
Explanation
Covered Interest Rate Parity is a critical concept in the international finance markets. It plays a significant role in the forex markets, preventing arbitrage opportunities by setting the forward exchange rate in such a way that it equalizes the interest rates of two economies.
In a world of perfect capital mobility and negligible transaction costs, covered interest rate parity helps in ensuring no risk-free profits can be made through currency conversion, borrowing, lending, and reconversion. Additionally, the principle of covered interest rate parity is often used by investors and corporations when they are dealing with foreign investments and international trade.
It aids in hedging the foreign exchange risk because, according to this principle, the forward exchange rate has already factored in the interest rate differential of the two countries. Therefore, it helps in predicting and managing the future exchange rate volatility while also contributing to an understanding of the relationship between future and spot rates.
It provides insights into changing market expectations about future currency values that is crucial in strategic planning for businesses operating in different currency zones.
Examples of Covered Interest Rate Parity
Covered Interest Rate Parity (CIRP) is an important principle in international finance that links interest rates, spot exchange rates, and forward exchange rates. Here are three real-world examples of CIRP:
Foreign Investment: An American investor considering investing in an asset in the UK must consider the future value of his investment not only in terms of UK interest rates but also the forward exchange rate between the dollar and pound. If the forward exchange rate does not offset the difference in interest rates between the two countries, there may be a covered interest rate arbitrage opportunity.
Currency Swap contracts: For example, a US company borrows funds in Japanese Yen because the interest rate is low, but its revenue is in USD. To protect against the risk of Yen appreciating, the company enters into a forward contract to swap the yen back into USD at an agreed rate upon maturity of the loan. Here, CIRP rule will apply as the forward exchange rate will be determined in such a way that it offsets the interest rate differential and precludes arbitrage opportunity.
Central Bank Interventions: The Swiss National Bank’s decision to cap the Swiss Franc’s value in 2011 can serve as an example. Investors were rushing to park their money in the country due to the Eurozone debt crisis, which resulted in the Swiss Franc’s appreciation. SNB introduced the cap to prevent severe impacts on Swiss exporters and the economy. However, to keep the exchange rate at the capped level, SNB had to lower its interest rate to deter inflows. CIRP would have ensured that even upon locking the future exchange rate at a certain level, the resulting interest rate is unattractive for investors.
FAQs on Covered Interest Rate Parity
1. What is Covered Interest Rate Parity?
Covered Interest Rate Parity refers to a state where the relationship between interest rates and the spot and forward currency values of two countries are in equilibrium. It means that an investor is indifferent to interest rates available in two countries because the forward exchange rate compensates for the differential in interest rates.
2. How is Covered Interest Rate Parity achieved?
Covered Interest Rate Parity is achieved when there is no arbitrage opportunity in the market. In other words, it’s achieved when no investor is able to make a risk-free profit through foreign exchange and interest rate discrepancies.
3. What is the significance of Covered Interest Rate Parity in financial markets?
Covered Interest Rate Parity has significant implications for foreign exchange markets. It forms the basis for foreign exchange hedging, currency risk analysis, and setting up interest rates in foreign exchange contracts. Additionally, deviations from Covered Interest Rate Parity provide insights into market inefficiencies or potential investment opportunities.
4. What factors can cause deviation from Covered Interest Rate Parity?
Transaction costs, political risk, tax considerations, and differing expectations about future exchange rates can lead to deviations from Covered Interest Rate Parity, as they could prevent the arbitrage necessary to maintain equality.
5. How is Covered Interest Rate Parity different from Uncovered Interest Rate Parity?
While both concepts pertain to rates of return, the key difference lies in how exchange rate risk is managed. In Covered Interest Rate Parity, the forward contract removes the exchange rate risk, while in Uncovered Interest Rate Parity, there’s no hedging instrument and hence, exchange rate risk is present.

- Forward Exchange Rate: This is a rate at which a currency can be exchanged for another in the future. It’s an essential term in Covered Interest Rate Parity as it allows for hedging against foreign exchange risk.
- Spot Exchange Rate: This term refers to the current price level in the market to exchange one currency for another. In Covered Interest Rate Parity, it helps in linking currencies of two countries mirroring their interest rates.
- Interest Rate Differential: This is the difference in interest rates between two countries. The differential plays a vital role in Covered Interest Rate Parity, where investments in different currencies should have the same return after adjusting for exchange rates.
- Arbitrage: In the context of finance and especially in the Covered Interest Rate Parity, this term refers to the practice of taking advantage of a price difference between two or more markets. It involves buying a security in one market and simultaneously selling it in another market to make a risk-free profit.
- Hedging: This is a strategy to reduce or eliminate the risk of future price fluctuations. Covered Interest Rate Parity relies on hedging as it involves an investor protecting against foreign exchange risk with a forward contract.
