The Strongest Forex Correlations

One of the most popular forex education articles that we have ever published is on the topic of correlations. As the world changes, so does the correlations between different currencies and different instruments. We want to take the opportunity to provide the latest correlation figures and to outline the top 3 correlations for each currency pair on a 1 month and 12 month basis. The stronger the correlation, the more likely the instruments will move in tandem, which in some cases means that you are doubling up on a position. The weaker the correlation between different currency pairs or instruments, the more diversification it provides to your portfolio. For example, over the past month if you were long the EUR/USD and short USD/CHF, you basically had 2 opposing trades that moved against each other 99 percent of the time, resulting in little profits. Meanwhile the 93 percent negative correlation between the VIX and the S&P 500 over the past month suggests that stocks are particularly sensitive to volatility and the reason why they are up is because volatility is low. These correlations can and will change with time but to be an effective trader, it is extremely important to understand how different currency pairs move in relation to each other to better understand your exposure and manage risk.

Here is the detailed breakdown of correlations for our more data savvy traders. We have tabulated the 1 month, 3 month, 6 month and 12 month absolute correlations between different currency pairs. Some traders also like to look at correlation on a 20 period average basis because the data is smoother and the numbers can be more reliable so we have provided this table at the very end. Enjoy!

Excellent Kathy. If I may, a quick comment on "the 93 percent negative correlation between the VIX and the S&P 500 over the past month suggests that stocks are particularly sensitive to volatility and the reason why they are up is because volatility is low.":

Correlation does not imply causality. Correlation is very useful for diversification, as you state as well in other words. Stocks are not up *because* volatility is low, this cannot be derived from a correlation measure. Also, the VIX does not really volatility lately, it is a measure of bearishness.When stocks drop, the VIX rises, but when stocks go up, the VIX declines, hence the negative correlation.

For correlations among all currency ETFs, there is a very useful chart here: http://2.bp.blogspot.com/_iV5yDiKxCdk/Suxa348wgVI/AAAAAAAACmQ/NsjcakUP7OU/s1600-h/currencies-sepoct09.jpg

You are absolutely right rsm which is why traders have to be careful with over interpreting the correlation data
