US Dollar Index and Crude oil price:
Crude oil as a commodity, its price is commonly affected by supply and demand as well as external factors, for example, global macroeconomic conditions, political, war, market speculation, the value of the U.S. Dollar, and so on. "But by far, the biggest factor that determines the oil price is the US dollar," says Donald Dony - opens the Technical Speculator investment newsletter. The US Dollar plays a major role in the price movements of crude oil. Trading crude oil often uses the US dollar as a medium, and its price movements in the US dollar have important consequences. Anyone who takes attention to crude oil and currency markets closely will find that the Crude Oil Price and Dollar Index generally trend in negative correlation. As the US dollar index is weaker, the price of crude oil is commonly in a rising trend, on the contrary, as the US dollar index is in strengthening or appreciating, the price of crude oil is in a falling trend.
