How to Understand Currency Pair Correlations for Beginners
Ever wondered how currency pair correlations affect each other in the forex market? Learning about forex pair correlation can simplify trading. This can help you manage risk better, and improve your overall strategies.
This guide will explain what correlation in currency pairs is, why it matters, and how you can use it effectively—all with examples you can relate to.
What Are Currency Pair Correlations?
In Forex trading, currency pair correlations describe how two currency pairs move in relation to each other. These relationships can be:
- Positive Correlation: Currency pairs with positive correlation move in the same direction.
For example, when EUR/USD rises, GBP/USD often rises too. It’s because Europe and the UK have strong economic ties.
- Negative Correlation: Currency pairs negative correlation means they move in opposite directions.
Therefore, when EUR/USD goes up, USD/CHF often goes down.
- No Correlation: Some pairs, like exotic pairs, move independently. If you’re wondering which currency pairs are not correlated, these are often the ones driven by unique local factors.
Correlations are measured on a scale from -1 to +1:
- +1: Perfect positive correlation (both move the same way).
- 0: No correlation.
- -1: Perfect negative correlation (they move in opposite directions).
For example, a +0.85 correlation between EUR/USD and GBP/USD means these pairs are closely aligned. Meanwhile, a -0.90 correlation between EUR/USD and USD/CHF indicates they move inversely.
Real-Life Examples of Currency Pair Correlations
Correlations are more than just numbers—they directly impact your trades. Here are some examples:
Example 1: Positive Correlation – EUR/USD and GBP/USD
During the 2021 post-Brexit recovery, both EUR/USD and GBP/USD gained value. It’s because economic conditions improved in Europe and the UK. Their positive correlation helped traders predict movements in both pairs.
Example 2: Negative Correlation – USD/JPY and AUD/USD
In 2022, rising US interest rates caused USD/JPY to strengthen while AUD/USD weakened. Japan’s reliance on costly imported energy drove the yen down.
Meanwhile, falling demand for Australian commodities hurt the Aussie dollar.
Example 3: No Correlation – USD/TRY and GBP/NZD
Unique political and economic conditions in Turkey and New Zealand mean these pairs rarely move together.
For example, in early 2023, USD/TRY spiked due to inflation, while GBP/NZD stayed stable. This is an example of which currency pairs are not correlated.
How to Calculate and Monitor Correlations
To find correlations, traders use tools like the Forex Correlation Matrix, MT4 indicators, or Excel spreadsheets.
Even without tools, comparing price charts over time can reveal patterns. For instance, a correlation pairs currency table:
An example of a Forex Correlation Matrix table:
| USD/JPY | GBP/USD | USD/CAD | NZD/USD | USD/CHF | EUR/USD | AUD/USD | |
|---|---|---|---|---|---|---|---|
| USD/JPY | -89 | 85 | -90 | 78 | -84 | -87 | |
| GBP/USD | -89 | -79 | 86 | -78 | 85 | 81 | |
| USD/CAD | 85 | -79 | -94 | 86 | -84 | -95 | |
| NZD/USD | -90 | 86 | -94 | -76 | 95 | 99 | |
| USD/CHF | 78 | -78 | 86 | -76 | -70 | -73 | |
| EUR/USD | -84 | 85 | -84 | 95 | -70 | 92 | |
| AUD/USD | -87 | 81 | -95 | 99 | -73 | 92 |
Such tables help traders quickly identify how pairs might move in relation to each other. It might show that EUR/USD and GBP/USD have a correlation of +0.85, indicating they usually move together.
Meanwhile, if EUR,/USD and USD/CHF show a correlation of -0.70, meaning they often move in opposite directions.
Why Do Correlations Matter?
1. Risk Management
If you trade two positively correlated pairs, like EUR/USD and GBP/USD, your risk doubles if the market moves against you.
Balancing trades with negatively correlated pairs, like USD/JPY and AUD/USD, can reduce risk.
2. Portfolio Diversification
Trading uncorrelated pairs spreads risk. For example, trading EUR/USD alongside USD/TRY prevents over-reliance on one market.
3. Trend Confirmation
If EUR/USD and GBP/USD show similar bullish trends, it reinforces your trading decision based on currency pairs with positive correlation.
4. Hedging Strategies
Using negatively correlated pairs, like USD/CAD and AUD/USD, can offset losses in one trade with gains in another.
Key Risks to Watch
While correlations are useful, they can be tricky:
- Dynamic Nature: Correlations change as markets evolve. For example, USD/JPY and AUD/USD showed strong correlation in 2020 but diverged in 2021.
- Overexposure: Trading many positively correlated pairs increases risk.
- Complexity: Managing multiple pairs can overwhelm beginners. Start simple and focus on a few pairs.
Practical Applications: Trading with Correlations
Scenario 1: Hedging with Negative Correlations
Suppose you expect EUR/USD to rise but fear volatility. Shorting USD/CHF, a negatively correlated pair, can protect your portfolio if EUR/USD falls.
Scenario 2: Using Commodity-Based Pairs
Australia and Canada’s economies rely on commodities exports. In 2023, rising oil prices strengthened AUD/USD but weakened USD/CAD. Knowing this can guide trades based on global trends. Here’s why:
Strengthened AUD/USD: Increased oil prices boosted the Australian economy. Therefore, this enhances the value of the AUD against the USD.
Weakened USD/CAD: The Canadian dollar (CAD) weakened due to negative factors ( A variety of factors: including geopolitical issues affecting oil supply or changes in global demand for oil). Hence, this affected Canada’s oil sector.
Scenario 3: Avoiding Overexposure
If you trade EUR/USD and GBP/USD simultaneously, losses in one will likely mirror the other. Diversify by including uncorrelated pairs, like USD/JPY.
Conclusion
Understanding forex pair correlation can simplify your trading decisions and improve your outcomes. If you manage risks, diversify your portfolio, and leverage correlations strategically, you can trade smarter.
