Discovering Relationship Between Dollar & Oil

Do you ever wonder if the strength of US Dollar that you are holding affects the price of oil or vice-versa? Here's an interesting article written on its likely relationship and perhaps put you in a better guidance when you should invest in the commodity of crude oil and/or gold.

Since the beginning of the year, the price of crude oil has increased by more than 30% from US$43 a barrel in January to a high of US$60 in mid-May. This could boil down to multiple factors, including improved growth prospects, speculation and the weakness of the US dollar. In addition, the outlook for economic giants the US and China has improved materially over the past month, leading many people to believe that the worst of the global recession is almost over.

US and Chinese economic data, along with comments from central bankers seem to support this rosy outlook. Early this month, US Federal Reserve chairman Ben Bernanke told the US Congress that the recession is easing and that growth should take place by year-end. Most other central bankers expect their countries to return to positive growth in 2010. Given that oil prices
plummeted in the second half of 2008 because of deleveraging and the fear of a deep
recession, the promise of a brighter tomorrow is driving oil prices higher. However, a slower pace of contraction and the prospect of increased demand are not the only reasons oil prices are higher.

Recent US dollar weakness is contributing to the recovery. Of course, many people will argue
that the US dollar is weaker because the US economy is doing better, which is true, but the
relationship between oil prices and the US dollar’s value is too significant to ignore.

Since the beginning of 2008, the correlation between oil prices and the US-dollar index has
been roughly -0.90. In other words, 90% of the time, when the US-dollar index falls, oil prices
rise.

The chart below shows the tight correlation between the two instruments:
Here's the argument for dollar driving the price of oil:
- Oil is priced in US dollars. According to OPEC, the relationship between oil prices and the dollar is almost mechanical. When the dollar falls, oil prices have to go up in dollar terms to stay constant in euro terms. Oil producers receive their oil revenues in US dollars and need to be compensated for the fluctuations of the greenback. This does not always hold true, of course, otherwise the correlation would not have broken in the beginning of the year.

Here's the argument for oil price driving the dollar:
- A study by the IMF in 1996 found that a 10% rise in the real price of oil induces a 2% real depreciation in a typical OPEC's real exchange rate. This should not be completely surprising because higher oil prices do result in higher cost of oil imports for the US, leading to a higher current account and trade deficit, which is US-dollar bearish. It also affects growth. When oil prices were nearing US$150 a barrel, gasoline prices in the US went as high as US$4 a gallon or more. It's like a tax on consumers and significantly affected companies!

The conclusion is that the relationship between oil prices and the US dollar is both schizophrenic and symbiotic. When oil prices were hitting record highs in July 2008, it can be argued that the price of oil was driving the value of the US dollar because of concerns about the strain it would have on the US economy. However, currently it is more likely that the dollar is driving the price of oil because the outlook for global demand is not clear and investors are less focused on the impact that higher oil prices can have on trade than they are on its signal of stronger growth.
