There is a negative correlation between dollar and crude oil. Under normal circumstances, when the dollar rises, crude oil will fall, and when the dollar falls, crude oil will rise. Because the United States is the largest consumer and importer of crude oil in the world, if the price of crude oil rises, it will bring a burden to the American economy and lead to the decline and fluctuation of the exchange rate of the US dollar. Moreover, the rise in crude oil prices will increase the cost of industrial development in the United States, so the price of crude oil will directly affect the US economy and the exchange rate of the US dollar.

Crude oil prices are affected by OPEC countries' oil production, non-OPEC countries' oil production and production costs. The rise and fall of the US dollar is influenced by the US economic situation, trade and other factors.
