Rising U.S. Dollar Impacts Commodities Worldwide

 | Mar 16, 2015 05:01AM ET

Believe it or not, you can learn everything you need to know about trading commodities in an Economics 101 class.

It’s all about supply and demand.

So why is trading in this sector so difficult to master?

Because supply and demand are an aftereffect of the various events that dictate them in the first place.

Unpredictable factors like Mother Nature , geopolitical events, and changing regulations all affect the supply and demand of commodities.

However, there is one consistent force that investors can count on that drives the commodities markets in a predictable way. And these days it’s going up, up, up…

h2 Forces of Nature, Politics, and People/h2

The outside forces I mentioned above put an ongoing downward pressure on the commodities markets.

Mother Nature, for one, can influence both the supply and demand sides of the equation and move markets. For example, a warm weather snap reduces the demand for heating oil, and a late frost can reduce the supplies of many crops.

Political and regulatory influences like taxes, subsidies, tariffs, and other trade restrictions can cut off the supply of a commodity, or make it difficult to import or export. Just consider what the current restrictions on Russia are doing to the natural gas and wheat markets.

There are also macro forces like global interest rates, market liquidity, capital flows, and trade balances.

China, for example, reported a USD 60.6-billion trade surplus in February 2015 – compared with a USD 22.9-billion deficit a year earlier – as exports surged while imports dropped. And even though this particular statistic is largely an outcome, rather than a cause of price movements, its announcement alone can move commodity prices from a predictive standpoint.

And then there are micro forces, such as raw material substitutes, commodity sector consolidation from mergers and acquisitions, and labor issues like strikes or accidents – such as a mine explosion or oil spill.

Additionally, environmental pressures can have a major effect on both production and consumption. Imagine how much more crude oil and natural gas supply there would be if hydraulic fracking wasn’t opening the floodgates of debate throughout so many countries.

What tends to happen when any of these influences exert force, is that not only does the cash (spot) price of commodities move, but so can the entire shape of its forward curve.

The forward curve can whipsaw between contango and backwardation, sometimes rapidly. In some cases, the curve takes the shape of a roller coaster, particularly when seasonality is a factor. This is typical in natural gas, for example.

Even with all of these factors in play, however, there is one force that can influence commodity movements more than anything else…

I’m talking about the US Dollar

h2 Staying U.S. Strong/h2

Since commodities around the world are priced in the U.S. dollar, a strong currency in the United States is great for all commodity consumers around the world.

A strong dollar makes commodities less expensive to import, irrespective of where the commodity was produced.

Thus, in today’s strong USD market, we have what economists would call an efficient market. That is, cheap commodities and a strong dollar.
