Written by:


Diving into the world of Forex, you’ll quickly discover that currency pairs are the stars of the show. But there’s more to it than just picking pairs at random. Understanding the subtle dance of correlation between them can be your secret weapon in navigating the complex Forex market.

You might be wondering why some currency pairs move in tandem while others seem to do their own thing. It’s all about correlation, a statistical measure that shows how pairs move in relation to each other. This knowledge isn’t just academic; it’s a practical tool to help you manage risk and uncover hidden opportunities.

Getting to grips with currency pair correlations can give you an edge in your trading strategy. Stick around, and you’ll learn how to use this info to make smarter, more informed trading decisions.

What are currency pairs in Forex?

When you’re venturing into the forex market, it’s crucial to understand the basics of currency pairs. They represent two different currencies traded against each other. The value of one currency is relative to the other, and it’s how you determine whether to buy or sell in the foreign exchange market.

Major Currency Pairs

Major currency pairs are the most traded in the forex market. These pairs always include the US dollar on one side and are known for their liquidity and lower spreads. Here’s a list you’ll come across most frequently:

  • EUR/USD (Euro/US Dollar)
  • USD/JPY (US Dollar/Japanese Yen)
  • GBP/USD (British Pound/US Dollar)
  • USD/CHF (US Dollar/Swiss Franc)
  • AUD/USD (Australian Dollar/US Dollar)
  • USD/CAD (US Dollar/Canadian Dollar)
  • NZD/USD (New Zealand Dollar/US Dollar)

These pairs are not only popular but also have significant economic data and news releases that can affect their value. Trading volume in these pairs means more opportunities and, often, tighter spreads.

Minor Currency Pairs

Minor currency pairs, sometimes referred to as cross-currency pairs, are those that do not include the US dollar. Instead, they’re made up of other major currencies. Minors still maintain high liquidity but may exhibit larger spreads than the majors. Some common minor pairs include:

  • EUR/GBP (Euro/British Pound)
  • GBP/JPY (British Pound/Japanese Yen)
  • EUR/AUD (Euro/Australian Dollar)
  • EUR/CAD (Euro/Canadian Dollar)
  • GBP/CAD (British Pound/Canadian Dollar)
  • CHF/JPY (Swiss Franc/Japanese Yen)

With minor pairs, you’re able to diversify your trading strategy beyond the confines of the USD-dominated world.

Exotic Currency Pairs

Exotic currency pairs involve a major currency paired with the currency from a smaller or emerging economy. Examples include:

  • USD/SGD (US Dollar/Singapore Dollar)
  • USD/HKD (US Dollar/Hong Kong Dollar)
  • EUR/TRY (Euro/Turkish Lira)
  • USD/ZAR (US Dollar/South African Rand)

Exotics are less liquid and tend to have much higher spreads. They can be susceptible to volatile swings, often driven by changes in domestic economies or political instability. Yet, for many traders, exotic pairs offer the allure of high potential gains from these rapid price movements.

Understanding currency pair correlation

In the Forex market, currency pairs don’t operate in isolation. Your ability to identify and understand correlations between different currency pairs can greatly affect your trading strategy and risk management. Correlation, in financial terms, indicates the degree to which two currency pairs move in relation to each other. An understanding of these movements and relationships can give you a significant edge in the market.

Positive Correlation

Currency pairs with a positive correlation move in the same direction. For instance, if you notice that when one currency pair rises in value, another pair tends to increase as well, they are considered to be positively correlated. This often happens with currency pairs that share a common currency. The most commonly traded positive correlations are between pairs like:


Take the EUR/USD and GBP/USD pair—when the US dollar weakens, both the Euro and the British Pound tend to strengthen against the US dollar, thus moving these pairs higher. Monitoring positive correlations can help you to avoid overexposure to a single currency, and hence manage your risk more effectively.

Negative Correlation

On the other hand, currency pairs with a negative correlation move in opposite directions. When you observe that one currency pair is moving up while another is moving down, that’s a clear indicator of negative correlation. This typically occurs between pairs where the base currency of one is the quote currency of the other. Some classic examples include:


For traders, negative correlation can serve as a form of hedging. If you hold positions in negatively correlated pairs, a loss in one position could potentially be offset by a gain in another, which may reduce the overall risk in your portfolio.

No Correlation

Currency pairs that have no correlation show no discernible relationship in their movements. In other words, the movement of one currency pair has no impact or predictability over the movement of another. This scenario exemplifies a lack of any direct or inverse correlation between two currency pairs. It’s important to realize that no correlation patterns can change over time due to economic, political, or global events affecting the markets. Pairs that may not have shown any correlation in the past can begin to develop one, and vice-versa. Therefore, always keep an eye out for shifts in correlations which might affect your trading strategies.

Correlation between currency pairs

Correlation Coefficient

When you’re navigating the forex market, understanding the correlation coefficient is crucial. It’s a statistical measure that quantifies the strength and direction of a relationship between two currency pairs. Ranging from -1 to 1, this value tells you how closely pairs move together or apart. A coefficient of 1 implies a perfect positive correlation, meaning they move in the same direction 100% of the time. A coefficient of -1 indicates a perfect negative correlation, with the pairs moving inversely. When the coefficient is 0, it means there’s no correlation and the pairs move independently of each other.

To get a clear picture, consider this scenario: if EUR/USD and GBP/USD have a correlation coefficient of 0.8, it signals a strong positive correlation, suggesting that they often move in the same direction.

Factors Affecting Correlation

Several key factors can influence the correlation between different currency pairs:

  • Monetary policies: Central banks’ decisions on interest rates can cause currency values to move in tandem or diverge.
  • Economic releases: Data such as employment figures or GDP reports can impact correlated pairs simultaneously if they share economic characteristics.
  • Political events: Elections or policy announcements can sway investor sentiment and affect correlated pairs.
  • Market sentiment: Global risk appetite or aversion can lead traders to move towards or away from certain currencies, affecting their correlations.

Remember, while currency pairs may show a certain correlation now, these relationships are not static and can change over time due to any of these influencing factors. It’s essential to stay updated with the latest economic, political, and market news as this might signal potential shifts in correlation, impacting your trading strategy.

Monitoring currency correlations is a dynamic and ongoing part of forex trading. It requires attention to detail and a willingness to adapt as the market evolves. Keep in mind that leveraging correlations can help you diversify, hedge, or double up on positions, but it’s not without risk. Always conduct thorough analysis and consider the broader market picture when considering correlated currency pairs in your forex endeavors.


You’ve uncovered the intricate web of connections that define the forex market. Grasping how currency pairs move in relation to one another is more than just academic; it’s a practical tool that sharpens your trading strategies. Whether you’re looking to diversify your portfolio, hedge against risk, or capitalize on market movements, a keen eye on these correlations is vital. Remember, the forex landscape is ever-shifting, and what holds true today may evolve tomorrow. Stay vigilant, keep learning, and use the knowledge of currency correlations to navigate the markets with confidence.
