See how currencies move relative to each other against NGN. Useful for portfolio diversification.
Correlation shows how closely two currencies move together. +1.0 = move together, -1.0 = move opposite, 0 = no relationship.
How to Use Correlation
High positive correlation (>0.7): Both currencies tend to rise/fall together against NGN.
High negative correlation (<-0.7): When one rises, the other tends to fall.
Low correlation (near 0): The currencies move independently.
Practical use: If you hold USD and GBP, check their correlation. High correlation means you have less diversification than you think.
