Le marché des changes (forex ou FX) est un réseau vaste et complexe où les devises sont échangées à l'échelle mondiale. Bien que de nombreuses transactions utilisent le dollar américain (USD) comme intermédiaire, une part importante implique des paires de devises dont aucune n'est le USD. Ces taux de change sont appelés croisements de taux.
Qu'est-ce qu'un Croisement de Taux ?
Un croisement de taux est simplement le taux de change entre deux devises, dont aucune n'est le dollar américain. Par exemple, le taux de change entre l'euro (EUR) et la livre sterling (GBP) est un croisement de taux (EUR/GBP). De même, le taux de change entre le yen japonais (JPY) et le dollar canadien (CAD) (JPY/CAD) est également un croisement de taux.
Comment les Croisements de Taux sont-ils Calculés ?
Bien que des cotations directes pour les croisements de taux existent, ils sont souvent dérivés indirectement en utilisant le USD comme point de référence. Cela se fait en utilisant les taux de change individuels de chaque devise par rapport au USD. Illustrons :
Supposons que nous ayons les taux de change suivants :
Pour calculer le croisement de taux EUR/GBP, nous pouvons utiliser la formule suivante :
EUR/GBP = (EUR/USD) / (GBP/USD) = 1,10 / 1,25 = 0,88
Cela signifie que 1 EUR achète 0,88 GBP.
Pourquoi les Croisements de Taux sont-ils Importants ?
Les croisements de taux jouent un rôle crucial dans la finance internationale pour plusieurs raisons :
Limitations des Calculs Indirects de Croisements de Taux :
Bien que pratique, le calcul indirect des croisements de taux à l'aide des taux de change USD peut introduire de petites inexactitudes dues aux spreads bid-ask (la différence entre le prix d'achat et le prix de vente d'une devise) et aux retards potentiels entre les cotations. Les cotations directes de croisements de taux provenant d'une source fiable sont toujours préférées lorsqu'elles sont disponibles pour une plus grande précision.
En Résumé :
Les croisements de taux sont un élément fondamental du marché des changes, facilitant le commerce et l'investissement internationaux. Comprendre comment ces taux sont calculés et leurs implications est vital pour toute personne impliquée dans la finance internationale, des multinationales aux investisseurs individuels. Bien que souvent dérivés des taux de change USD, l'accès aux cotations directes de croisements de taux minimise les erreurs de calcul potentielles et offre une plus grande précision dans l'analyse financière et la prise de décision.

Scenario: You are a trader working for a multinational corporation. You need to determine the exchange rate between the Australian dollar (AUD) and the Swiss franc (CHF). You have the following exchange rate information:
Task: Calculate the AUD/CHF cross rate. Show your work.
To calculate the AUD/CHF cross rate, we first need to find the USD/CHF rate which is the inverse of CHF/USD: USD/CHF = 1/0.95 = 1.0526 Then, we can calculate AUD/CHF using the formula: AUD/CHF = AUD/USD * USD/CHF = (1/0.70) * 1.0526 = 1.5037 Therefore, 1 AUD buys approximately 1.5037 CHF.
This chapter details the various techniques used to calculate and utilize cross rates in foreign exchange trading. We've already seen the most common method, but let's explore it further and introduce alternatives.
1.1 The Indirect Method (using USD as an intermediary):
This method, already explained in the introduction, involves utilizing the exchange rates of each currency against the US dollar to derive the cross rate. The formula remains:
Cross Rate (Currency A/Currency B) = (Currency A/USD) / (Currency B/USD)
It's crucial to ensure the exchange rates used are from the same source and as close to the same time as possible to minimize discrepancies. Different sources may have slightly varying quotes, leading to minor differences in the calculated cross rate.
1.2 The Direct Method:
Ideally, the most accurate cross rate is obtained directly from a forex market data provider. Many platforms offer direct quotes for a wide range of currency pairs, eliminating the need for calculation and reducing the chance of errors. This is the preferred method when available.
1.3 Using Multiple Intermediaries:
In situations where neither currency has a direct USD quote readily available, we can use multiple intermediary currencies to calculate the cross rate. For instance, to find EUR/JPY, we could use USD and GBP as intermediaries, first calculating EUR/GBP, and then GBP/JPY, and finally combining them to arrive at the EUR/JPY rate. However, this method is susceptible to greater inaccuracies due to the compounding effect of multiple exchange rate differences.
1.4 Considering Bid-Ask Spreads:
The bid-ask spread (the difference between the buying and selling price of a currency) introduces uncertainty into the cross rate calculation. While the formula uses the mid-market rate, the actual rate obtained when executing a trade will likely fall somewhere within the spread. Traders need to factor this into their calculations and strategies.
Predicting cross rate movements is a complex undertaking, with no single model guaranteeing accuracy. However, several models and techniques are used by traders and analysts to forecast trends and potential price changes.
2.1 Fundamental Analysis:
This approach focuses on macroeconomic factors influencing exchange rates. These factors include:
2.2 Technical Analysis:
This method uses historical price data and chart patterns to identify trends and predict future movements. Technical indicators like moving averages, relative strength index (RSI), and MACD are commonly employed.
2.3 Econometric Models:
Sophisticated statistical models like regression analysis and time series models can be used to forecast cross rates. These models attempt to capture the relationships between various economic indicators and exchange rates.
2.4 Sentiment Analysis:
Analyzing news articles, social media trends, and other forms of market sentiment can provide insights into the potential direction of cross rates. Positive sentiment generally pushes prices upward, while negative sentiment can lead to declines.
2.5 Limitations:
It's important to acknowledge the limitations of all these models. Exchange rates are influenced by a vast number of factors, making accurate predictions challenging. Unexpected events or shifts in market sentiment can easily disrupt forecasts.
Several software applications and online tools facilitate cross rate analysis and trading.
3.1 Forex Trading Platforms:
Most forex brokers provide platforms with real-time cross rate quotes, charting tools, and order execution capabilities. These platforms often include technical analysis indicators and allow for automated trading strategies. Examples include MetaTrader 4 & 5, cTrader, and proprietary platforms offered by various brokers.
3.2 Data Providers:
Companies such as Refinitiv, Bloomberg, and Trading Economics provide comprehensive market data, including historical and real-time cross rate information. This data can be used for analysis, backtesting trading strategies, and developing custom models.
3.3 Spreadsheet Software:
Programs like Microsoft Excel or Google Sheets can be used for calculating cross rates, performing basic statistical analysis, and creating custom charts and visualizations.
3.4 Programming Languages:
Python and R, among other languages, offer libraries and tools for accessing market data, performing sophisticated statistical analysis, and building custom trading algorithms.
Effective use of cross rates requires careful consideration of several best practices:
4.1 Data Quality:
Ensure data is obtained from reliable and reputable sources. Inconsistent or inaccurate data can lead to flawed analyses and incorrect decisions.
4.2 Timeliness:
Exchange rates fluctuate constantly. Use the most up-to-date quotes available, especially for trading purposes. Time lags in data can significantly impact accuracy.
4.3 Transparency and Documentation:
Maintain clear records of data sources, calculations, and assumptions made during analysis. This ensures transparency and allows for easier auditing and review.
4.4 Risk Management:
Implement appropriate risk management strategies when trading cross rates, including setting stop-loss orders and diversifying positions to mitigate potential losses.
4.5 Continuous Learning:
The forex market is dynamic. Staying informed about market trends, economic developments, and new analytical techniques is crucial for success.
This chapter presents real-world examples demonstrating the applications and implications of cross rates:
5.1 Case Study 1: Arbitrage Opportunity:
Imagine the following rates: EUR/USD = 1.10, GBP/USD = 1.25, and EUR/GBP (market rate) = 0.87. The calculated EUR/GBP cross rate is 1.10/1.25 = 0.88. This discrepancy (0.88 vs 0.87) presents a potential arbitrage opportunity. A trader could profit by buying EUR with GBP in the market and simultaneously selling EUR for USD, and buying GBP with USD, effectively exploiting the difference.
5.2 Case Study 2: Hedging Currency Risk:
A UK-based company exporting goods to the Eurozone faces currency risk. By using forward contracts or options based on the EUR/GBP cross rate, the company can hedge against potential losses stemming from fluctuations in the exchange rate.
5.3 Case Study 3: International Investment Decisions:
An investor comparing investments in European and UK equities needs to consider the EUR/GBP cross rate to accurately assess the relative returns in their local currency.
5.4 Case Study 4: Pricing Goods for International Markets:
A US company selling products in Japan must use the USD/JPY cross rate to determine the Yen price of its goods, ensuring competitiveness and profitability in the Japanese market. This example can be extended to show how various currency pairs, even involving multiple cross rates, are used for pricing.
These case studies illustrate the practical significance of cross rates across various facets of international finance and business. Understanding these applications is essential for anyone navigating the complexities of the global economy.
