Predicting the next move in the markets is the key to making money in trading, but putting this simple concept into action is much harder than it sounds. Professional forex traders have long known that trading currencies requires looking beyond the world of FX. The fact is that currencies are moved by many factors - supply and demand, politics, interest rates, economic growth, and so on. More specifically, since economic growth and exports are directly related to a country's domestic industry, it is natural for some currencies to be heavily correlated with commodity prices. The top three currencies that have the tightest correlations with commodities are the Australian dollar, the Canadian dollar and the New Zealand dollar. Other currencies that are also impacted by commodity prices but have a weaker correlation are the Swiss franc and the Japanese yen. Knowing which currency is correlated with what commodity can help traders understand and predict certain market movements. Here we look at currencies correlated with oil and gold and show you how you can use this information in your trading. (For background reading, see The Most Popular Forex Currencies.)
Figure 1 shows the clearly positive relationship between oil and the Canadian loonie. In fact, it should come as no surprise that the price of oil actually acts as a leading indicator for the price action of the CAD/USD. Since the traded instrument is the inverse, or USD/CAD, it's important to note that based on the historical relationship, when oil prices go up, USD/CAD falls and when oil prices go down, USD/CAD rises.

Oil and the Japanese Economy
At the other end of the spectrum is Japan, which imports nearly all of its oil (compared to the U.S., which imports approximately 50%). As of 2011, it is the world's third-largest net oil importer behind the U.S. and China. Japan's lack of domestic sources of energy, and its need to import vast amounts of crude oil, natural gas and other energy resources, make it particularly sensitive to changes in oil prices. Japan also lacks the flexibility to switch to nuclear power because it is a huge net importer of uranium for its nuclear power plants. As of 2008, the country's dependence on imports for primary energy stood at more than 84%. Oil provided Japan with 49% of its total energy needs, coal with 20%, nuclear power 13%, natural gas 14%, hydroelectric power 3% and renewable sources a mere 1%. Therefore, when oil prices skyrocket, the Japanese economy suffers. (Hedge against rising energy prices and diversify your portfolio; read ETFs Provide Easy Access To Energy Commodities.)
An Attractive Oil Play: CAD/JPY
Looking at this from a net oil exporter/importer perspective, the currency pair that tops the list of currencies to trade to express a view on oil prices is the Canadian dollar against the Japanese yen. Figure 2 illustrates the tight correlation between oil prices and CAD/JPY. More often than not, oil prices tend to be the leading indicator (as with USD/CAD) for CAD/JPY price action with a noticeable delay. As oil prices continued to fall during this period, CAD/JPY broke the 100 level to hit a low of 76.

Going for Gold
Gold traders may also be surprised to hear that trading the Australian dollar is just like trading gold in many ways. As the world's third-largest producer of gold, the Australian dollar had an 84% positive correlation with the precious metal between 1999 and 2008. Generally speaking, this means that when gold prices rise, the Australian dollar appreciates as well. The proximity of New Zealand to Australia makes Australia a preferred destination for exporting New Zealand goods. Therefore, the health of New Zealand's economy is closely tied to the health of the Australian economy, which explains why the NZD/USD and the AUD/USD have had a 96% positive correlation over the same time period. The correlation of the NZD/USD with gold is slightly less than that of the Australia dollar but is still strong at 78%.

A weaker, but still important, correlation is that of gold prices and the Swiss franc. The country's political neutrality and the fact that its currency used to be backed by gold have made the franc the currency of choice in times of political uncertainty. From January 2006 until January 2009, USD/CHF and gold prices had a 77% positive correlation. However, the relationship broke down somewhat in September 2005 as the U.S. dollar decoupled from gold price movements.

Trading Currencies as a Supplement to Trading Oil or Gold
For seasoned commodity traders, it may also be worthwhile to look at trading currencies as an alternative or a supplement to trading commodities. In addition to being able to capitalize on a similar outlook (e.g. higher oil), traders may also be able to earn interest if they are on 2% margin or higher with most brokers. When trading currencies, you are dealing with countries, and countries have interest rates, of course. For example, a trader who may have bought the AUD/USD in March 2009 would be able to earn up to 3% in interest income if Australian interest rates remained at 3.25% and U.S. interest rates remained at 0.25% for the entire year. The 3% comes from taking Australia's central bank rate, which is the amount earned, and subtracting the nearly 0% rates paid for shorting the U.S. dollar. These are unleveraged rates, which mean that with 10 times leverage, for example, net of any exchange rate changes, the interest income would be that much higher. Leverage also makes the trade riskier, which means that if the trade turns against you, losses will be larger.
Along the same lines, if you shorted AUD/USD to express a short gold view, you would end up paying interest. If you're a commodity trader looking for a bit of a change from the usual pro gold trade (for example), commodity currencies such as the AUD/USD and NZD/USD provide good opportunities worth looking into.
If you want to trade commodity currencies, the best way to use commodity prices in your trading is to always keep one eye on movements in the oil or gold market and the other eye on the currency market to watch how quickly it responds. Due to the slightly delayed impact of these movements on the currency market, there is generally an opportunity to overlay a broader movement that is happening in the commodity market to that of the currency market. Bottom line: It never hurts to be more informed about commodity prices and how they drive currency movements.
