Correlation of variables

A statistical measure referring to the extent of linear relationship between two or more variables, in other words, of the degree to which the movements of two currency pairs are related. For example, if two currency pairs have a high correlation, their prices tend to rise and fall in sync. Although the measure suggests some causal relationship between the variables, the relationships between pairs and the correlation values tend to change from time to time.

The standard measure of correlation is the correlation coefficient, a number between -1 and 1 that indicates the strength and direction of a the linear relationship. A correlation coefficient of -1 indicates that the currency pairs are perfectly negatively correlated, that is, a higher value for one pair tends to correspond to a lower value for the other. A correlation coefficient of 1 means that they are perfectly correlated, indicating a higher value for one variable tends to correspond to a higher value for the other. The weaker the relationship, the closer the correlation coefficient is to 0.

Data Matters: Vanishing volatility, crumbling correlations – HSBC

Knowing how closely correlated the currency pairs are in your portfolio is a great way to measure your exposure and risk. You might think that you're diversifying your portfolio by investing in different pairs, but many of them have a tendency to move in the same or opposite direction to one another. The correlations between pairs can be strong or weak and last for weeks, months, or even years. [...] Any correlation calculation will be in decimal form; the closer the number is to 1, the stronger the connection between the two currencies.

[...] Just as on the positive side, the closer the number is to -1, the more connected the two currencies movements are, this time in the opposite direction.

[...] the most important aspect to remember when analysing currency correlations is that they can also easily change over time.
