1. Relationship between crude oil and the US dollar: There is a negative correlation between crude oil and the US dollar, that is, when the US dollar depreciates, assuming that the value of gold remains unchanged (note that it is not the price), then more US dollars are needed to represent its value, which will reflect the increase in the price of gold.
2. The true value of the US dollar: oil is a physical object, and the true value of the physical object remains unchanged. But the dollar is a value currency endowed by law and has no legal value. Dollars are the value of a piece of paper. If the dollar depreciates, oil, a physical resource, will maintain its original value, but the dollar is not its original value.
