First of all, you should know that the international crude oil price is directly linked to the US dollar, just like gold. If every country wants to buy oil, it must first change its currency into dollars, and then buy and sell oil. What's a dollar? Since the establishment of the Bretton Woods system, the US dollar has been equivalent to the world currency. A while ago, the oil price rose to more than 1400 US dollars, and its impact on the world is self-evident. The progress of today's society is still inseparable from the contribution of industry, and the source power of industry is oil. The rise and fall of oil determines the production and operation costs of these industrial manufacturers. Just because the oil price soared a while ago, I don't know how many companies will go bankrupt in an instant. Of course, if the oil producer has money, the intermediate processing will be finished. Think about it, even if you dig for oil again, what's the use of no one processing it? In addition, cars are all over the world, and oil price is the first consideration for every owner. If the oil price is so high, who will buy a car? If the car can't be sold, the car tycoons will have a hard time, and their company's share price will fall, and the chain reaction is self-evident. Recently, with the depreciation of the dollar, the oil price has dropped to more than 40 dollars. On the contrary, crude oil companies like PetroChina and Sinopec began to lose money again, which is the same reason. So oil prices always affect people's hearts, companies' hearts and even countries' hearts ~ ~
