Crude oil is denominated in dollars, so it indirectly reflects the rise and fall of the dollar. Also, high crude oil prices bring inflation to countries, so the rise and fall can reflect some fundamentals of the global economy. Also, if crude oil rises, it means that there is a great demand for global economic prosperity. Sometimes, after the global economic recession, the price of crude oil falls for fear of decreasing demand. In addition, it is also associated with gold and other commodity attributes.
