The United States tasted the sweetness of being a "world currency" and discovered oil, which is called industrial blood oil, because the distribution of oil is extremely uneven, and almost all countries need oil;

Therefore, in the 1970s, the United States reached an agreement with Saudi Arabia, the largest oil producer in the world. The two sides decided to use the US dollar as the sole pricing currency for oil, and obtained the consent of other members of the Organization of Petroleum Exporting Countries.

To put it simply, the United States first controlled a few oil exporting countries, so that when they sell oil, they must be denominated in dollars. Then if other countries want to buy oil, they must buy it in dollars, and they must reserve a lot of dollars. Therefore, the dollar has once again become indispensable in global trade, and the dollar has formally established its global hegemony as a world currency.

The reason why the expanded data dollar occupies a dominant position is because the United States is behind the dollar, with stable exchange rate, high security, good liquidity and international trust in the United States. At the same time, allies also believe that their international interests are consistent with those of the United States. However, in recent years, a series of actions by the United States have made the status of the dollar increasingly marginalized.

In order to make American crude oil the first choice among the world's oil demanders, the United States has repeatedly sanctioned Iran, Russia and other oil countries.

Trump first imposed severe financial sanctions on Russia. At the same time, after the United States withdrew from the Iranian nuclear deal, it began to threaten Iranian and European companies trading in dollars to curb Iran's oil exports, and then issued an oil ban to prohibit other countries from importing oil from Iran.
