UNDERSTANDING CURRENCY CORRELATIONS AND CORRELATION TRADING IN FOREX
EXAMPLES OF POSITIVE AND NEGATIVE CORRELATIONS
We’ve touched on positive and negative correlations above, but which currency pairs fall into these categories? Take a look at a few examples.
POSITIVELY CORRELATING FX PAIRS
Positive forex correlation pairs are not all equal. Some will tend to correlate more closely, replicating each other’s movements almost exactly in some cases. Others will move only slightly in the same direction, but will show a repeated correlation over time.
Some of the most correlated pairs include:
The AUD/USD pair against the NZD/USD pair.
The EUR/USD pair against the GBP/USD pair.
The EUR/USD pair against the USD/CHF (Swiss Franc) pair.
The GBP/USD pair against the USD/CAD (Canadian Dollar) pair.
The GBP/USD pair against the USD/CHF pair.
Bear in mind that these pairs may not necessarily correlate at all times, and that strong correlations between other pairs may emerge over time.
NEGATIVELY CORRELATING FX PAIRS
Just like with positive currency correlations, negative correlations are also far from equal. There will be some negatively correlating pairs that more closely match the magnitude of each other’s movements, while others may move only slightly. Identifying and understanding these negative correlations is an important part of forex trading.

Some examples of negatively correlating FX pairs include:
* The USD/CHF pair against the EUR/USD pair.
* The GBP/USD pair against the USD/CHF pair.
* The USD/CAD pair against the AUD/JPY pair.
* The USD/JPY pair against the AUD/USD pair.
* The GBP/USD pair against the USD/JPY pair.
Again, bear in mind that negatively correlated forex pairs do not provide guarantees into future market movements. You will need to take care when you trade, and remember that a loss is possible even if you expect a strong correlation.
TRADING WITH CURRENCY CORRELATIONS
When you trade on the forex market, you are likely to use currency correlations in one of two ways.
Gathering evidence for forecasting
You may notice a trading signal or indicator that suggests a specific price movement for a currency pair. While these signals and indicators are useful when deciding on a trading strategy, it’s not unusual for traders to want to gather more information before they make a decision one way or another.
Looking at forex pairs that correlate with one another can provide this additional insight. For instance, you may predict that a pair is going to move in a specific direction, and you identify a history or correlation with another pair. A movement in this second pair will provide supporting evidence that suggests your prediction was correct, and you may decide to open a position as a result. You may also decide to increase your exposure to market forces by trading on the margin or by leveraging your forex position — just remember that this also raises the risk level for the trade. There are no guarantees of success, but this is an example of a considered strategy used by experienced traders.
Hedging other trades
Correlating forex pairs are also used in hedging strategies, where FX traders seek to mitigate the risk of one position by opening another. Understanding the correlations between different pairs is useful here, as traders can recoup some of their potential losses with a trade in the opposite direction.
The most obvious way to do this is to use negatively correlating forex pairs. You may open a position — either buying (long) or selling (short) on one currency pair, and then open the same position on a negatively correlating pair. If your first position fails, you will still make a return on the second position, provided that the correlation occurs as expected.
However, you can also hedge with two positively correlated pairs. To do this, you would open a position on the first pair — either a long or a short position — and then open the opposite position on the second pair. Again, if the first position fails, you would still make some return from the second position if the correlation is realised, mitigating your losses to some extent.
When you trade with currency pairs, you need to be aware of spreads . The spread is the difference between the buying and selling prices for a pair, and this essentially represents the fee you will need to pay to open a position. With hedging on currency correlations, you will be opening two positions rather than one, which means you’ll need to pay two sets of trading fees. This makes it doubly important to keep spreads in mind.
