Why should oil be settled in dollars? After the end of World War II, 70% of gold was in the United States, and the shortage of gold for trading oil in the market led to difficulties and confusion in trading. Saudi Arabia is the largest oil exporter in the world, with huge oil reserves (about 260.86 billion barrels of proven oil reserves at the end of 20 17). The dominant position and the Saudi royal family are easy to be bought, so the United States chose Saudi Arabia as the negotiating object. Later, an agreement was reached to force the Organization of Petroleum Exporting Countries to ensure that all crude oil transactions were settled in US dollars. Until now, the US dollar is still the main transaction settlement currency for major crude oil.

Saudi Arabia has gained lasting status and security, while the United States has settled in US dollars, and other OPEC countries can conduct oil transactions normally and happily. On the surface, it seems to be a three-legged situation.

And how does the United States use the dollar to make a profit? Crude oil, also known as black gold, is an important strategic resource for a country's development. Why did Japan attack Pearl Harbor in the United States during World War II? It is precisely because 194 1 the United States imposed an embargo on Japan, which cut off Japan's oil road to China. Japan realizes the crisis of data exhaustion, and it will die if it doesn't attack the United States, and then it will fight to the death.

If you need to buy oil in the market, you must have US dollars, so you must hold US dollar reserves. If you want to reserve dollars, you need to buy foreign exchange currencies and US Treasury bonds, which will increase the purchasing power of dollars. The key is that the American currency, the US dollar, is printed by itself, so the United States is empty-handed, and gradually the US dollar will become a common currency.

After the US dollar becomes the universal currency in the world, only a few pieces of waste paper are needed to buy goods from all over the world, that is to say, the United States keeps printing money and then buy buy buys it. There are many ways to shave in America.

The dollar plays an important role in the world economy and can also be used as a political tool. The United States has the pricing power of dollars, which can affect the price of oil. Many countries in the world rely on oil exports, and when oil prices keep plugging water, it will seriously affect the domestic economy. Such as Venezuela, Russia, Iran, Iraq and Saudi Arabia.
