Key takeaways:
- A cross rate is the exchange rate between two non-USD currencies, calculated using a shared third currency, typically the US dollar.
- It allows for currency conversion when a direct exchange rate isn’t available, enabling efficient international trade and investment.
- Cross rates are essential in forex trading, where traders use them to speculate, hedge, or manage multi-currency exposure globally.
In the world of forex, understanding currency exchange is crucial for businesses engaged in international trade. One important concept in this realm is the cross rate.
Read below to explore what a cross rate is, how it works, and its significance in foreign exchange markets.
Cross rates explained
A cross rate is the exchange rate between two currencies, calculated using a third currency as a reference.
This is particularly useful when there is no direct exchange rate available between the two currencies in question.
For instance, if a business wants to know the exchange rate between the euro (EUR) and the Japanese yen (JPY), but only has access to the GBP/EUR and GBP/JPY (British pound sterling/ euro and British pound sterling/ Japanese yen) currency pairs and their rates, it can calculate the cross rate using these two rates.
Importance of cross rates in global finance
Cross rates play a significant role in global finance, particularly for businesses that operate in multiple currencies. They facilitate international trade by providing a means to evaluate costs and pricing in different currencies.
By understanding cross rates, businesses can make informed decisions regarding pricing strategies, hedging against currency fluctuations, and managing foreign exchange risk.
Understanding currency exchange
Currency exchange is the process of converting one currency into another, a necessity for businesses operating across borders. The value of currencies fluctuates based on various factors including economic indicators, market sentiment, and geopolitical events. These fluctuations create opportunities and risks for businesses involved in international transactions.
For instance, a sudden change in interest rates from central banks can lead to a rapid currency appreciation or currency depreciation, impacting the cost of imports and exports. Consequently, companies must stay informed about global economic trends and potential political upheavals that could affect exchange rates.
The basics of foreign currency pairs
When discussing currency exchange, it’s essential to understand currency pairs.
Foreign currency pairs consist of two currencies, where the first currency is the base currency and the second is the quote currency. For example, in the pair GBP/USD, British pound sterling (GBP) is the base currency and the US Dollar (USD) is the quote currency.
The exchange rate indicates how much of the quote currency is needed to purchase one unit of the base currency. Traders often analyse these pairs to predict market movements, using various strategies such as technical analysis and fundamental analysis to make informed decisions, particularly for currency risk management.
Additionally, the liquidity of certain pairs can vary significantly, with major currency pairs like EUR/USD being more actively traded than exotic pairs, which can lead to wider spreads and increased volatility.
How are cross rates calculated?
As mentioned, cross rates are exchange rates between two currencies that are not directly quoted against each other, but instead are derived through a common third, intermediary currency—most often the US dollar (USD). This method is commonly used in international finance and foreign exchange markets to facilitate conversions between currencies that do not have a widely published direct rate.
To calculate a cross rate, you divide one currency pair rate by another, using the shared base currency to establish a link between the two. This allows traders, businesses, and travellers to find the exchange value between two non-USD currencies with accuracy and consistency.
Cross rate general formula:
To calculate a cross rate, you need the exchange rates of Currency A and Currency B against a common base currency—let's call it Currency C.
If you have:
- Currency C/A = the exchange rate of Currency C to Currency A
- Currency C/B = the exchange rate of Currency C to Currency B
Then the cross rate from Currency A to Currency B is calculated as: A/B = (C/B) ÷ (C/A)
In other words, divide the exchange rate of Currency B against the base currency by the exchange rate of Currency A against the same base currency. This gives you the value of 1 unit of Currency A in terms of Currency B.
Cross rate calculation example: EUR/JPY
Let’s say you want to calculate the exchange rate from euros (EUR) to Japanese yen (JPY), using USD as the common base currency. You have the following rates:
- USD/EUR = 1.10 (1 USD buys 1.10 EUR)
- USD/JPY = 145.00 (1 USD buys 145 JPY)
Using the formula:
- EUR/JPY = USD/JPY ÷ USD/EUR
- EUR/JPY = 145.00 ÷ 1.10 = 131.82
So, 1 euro = 131.82 Japanese yen.
This calculation allows businesses to determine the value of the euro in terms of yen, even if they do not have a direct EUR/JPY rate available.
Cross rate calculations like this are essential in forex markets, international trade, and global finance—especially when dealing with less commonly traded currency pairs.
How do cross rates affect exchange rate forecasting?
Cross rates play a significant role in exchange rate forecasting, particularly when analysts and businesses need to understand the relative value of two non-USD currencies.
Because most major currencies are quoted primarily against the US dollar, cross rates must often be derived rather than observed directly. This indirect relationship introduces additional complexity into forecasting models and market analysis.
Dependency on USD movements
Since cross rates are typically calculated using two USD-based currency pairs, any fluctuation in the US dollar can indirectly affect the derived cross rate, even if the two currencies in question haven’t moved relative to each other.
For example, if the USD strengthens sharply, both USD/EUR and USD/JPY might fall, affecting the calculated EUR/JPY cross rate.
As a result, forecasting a cross rate requires not just an analysis of the two currencies involved, but also an understanding of how each interacts with the common base currency (often USD).
Interest rate differentials and monetary policy
Cross rate forecasts must account for central bank policies in each currency's region. If the European Central Bank (ECB) is expected to raise interest rates while the Bank of Japan (BoJ) maintains low rates, the EUR/JPY cross rate is likely to rise, even if the USD remains stable.
Analysts must therefore monitor monetary policy, inflation trends, and macroeconomic data in all relevant economies.
Market sentiment and risk appetite
Some currencies (like the Japanese yen or Swiss franc) are considered “safe haven currencies", while others (like the Australian dollar) are viewed as risk-sensitive.
Cross rate movements can reflect shifts in global risk appetite. For instance, in times of market stress, JPY may strengthen across the board, pushing down cross rates like GBP/JPY or EUR/JPY.
Arbitrage opportunities
Discrepancies between direct and cross rate calculations can also reveal short-term arbitrage opportunities. Traders and algorithms constantly monitor these differences, and any inefficiencies are quickly corrected. This dynamic interaction means that cross rates not only reflect underlying fundamentals but are also influenced by short-term market mechanics.
In summary, cross rates add a layer of complexity to exchange rate forecasting. They require a multidimensional view of currency dynamics, factoring in US dollar movements, local economic conditions, and global investor behaviour. For accurate predictions, forecasters must model both direct and indirect currency relationships with care.
Conclusion
Understanding cross rates is essential for businesses engaged in international trade and finance. By grasping the concept of cross rates, companies can make informed decisions regarding pricing, risk management, and investment strategies.
