Correlation Between Currencies in the Forex Market
The correlation between currencies in the forex market is a measure that shows the relationship between the price movements of different currency pairs. It is often expressed by an index called the correlation coefficient, which ranges from +1 to -1.
There are two types of correlation: positive and negative.
A) Positive Correlation (+1):
This occurs when the price movements of currency pairs change in the same direction. Both pairs are either moving upward or downward. For example, the EUR/USD and GBP/USD pairs often show a positive correlation, as do the AUD/USD and NZD/USD pairs, because both are influenced by fluctuations in the US dollar.
B) Negative Correlation (-1):
This occurs when the price movements of currency pairs change in opposite directions. One pair moves upward while the other moves downward, meaning the two currencies are moving in opposite directions. For instance, the EUR/USD and USD/CHF pairs may show a negative correlation, where an increase in the dollar against the euro leads to a decrease against the franc, and vice versa.
Importance of Currency Correlation in Forex:
Understanding currency correlation is important for traders for the following reasons:
Risk Management:
It helps avoid exposure to risk in a single currency, reducing the potential for large losses if trades are based on correlated currency pairs.
Hedging Strategies:
Traders can use inversely correlated pairs to hedge against risks. These trades can offset losses if the market moves against expectations, much like a hedge, but with different pairs. However, this will also reduce overall profits somehow.
Trading Opportunities:
When deviations occur between the movements of correlated currency pairs, traders may see this as an opportunity to anticipate price convergence or exploit price differences between different currencies.
