Overview
Currency pairs can be positively or negatively correlated. EUR/USD and GBP/USD often move together; EUR/USD and USD/CHF often move inversely. Correlated positions amplify risk; diversify or adjust size accordingly.
Positive Correlations
Positively correlated pairs move in the same direction. EUR/USD and GBP/USD both tend to rise or fall together because they share the dollar. Long EUR/USD and long GBP/USD is effectively a double bet on dollar weakness. One loss often means both lose.
Negative Correlations
Negatively correlated pairs move in opposite directions. EUR/USD and USD/CHF often move inversely (CHF is a dollar proxy). Long EUR/USD and long USD/CHF can offset each other, but they can also both lose in certain conditions.
Diversification
Avoid holding multiple highly correlated positions. If you are long EUR/USD, adding GBP/USD increases concentration, not diversification. Either reduce size on correlated pairs or choose uncorrelated pairs to spread risk.
Practical Rules
Check correlation before adding a position. If two pairs are 0.8+ correlated, treat them as one position for sizing. Use a correlation matrix or broker tools. Adjust lot size when holding correlated exposure.
