The rise of international crude oil several times is not good for all enterprises, because it means that the price of raw materials rises and the production cost rises. The corresponding price of petroleum products should rise, but the commodity price of an industry is stable in a short time, which makes the sales price basically stable, so the original price rises and the profit margin of enterprises is very small. If the price of crude oil rises for a long time, the industry will also increase the product price accordingly, so that the sales price will rise, but the sales volume will also decrease to a certain extent. Therefore, the rise in crude oil prices is bad for any oil-related enterprise. If the local currency appreciates, it depends on the strength of petrochemical enterprises to import crude oil raw materials, which is equivalent to buying more foreign products at home with the same amount of money, but it is very unfavorable for exports. After the domestic output value of the same thing remains unchanged but the local currency appreciates, the convertible dollar (using the dollar as the common currency) will decrease and become negative. I don't know what the source of Sinopec crude oil is, just look at its raw material source and product sales direction.
