On the global economic chessboard, the U.S. dollar index, gold and crude oil are three important chess pieces. The relationship between them is complex and mutually restrictive, and they jointly affect the direction of the world economy. The U.S. dollar index comprehensively reflects the exchange rate of the U.S. dollar in the international foreign exchange market and is an important tool for measuring changes in the U.S. dollar's exchange rate against a basket of currencies. In the 1970s, the close connection between the US dollar and oil was formally established, and the US dollar became the only pricing currency for oil. When the dollar appreciates, oil becomes relatively more affordable; when the dollar weakens, oil becomes more expensive.

Generally speaking, when the U.S. economy performs strongly, international oil prices rise and the U.S. dollar appreciates. The US dollar is often a "safe haven" for funds, so when a large amount of funds choose the US dollar as a "safe haven", these funds are likely to flow out of the international crude oil market, which will make the US dollar index strengthen and international oil prices weaken.

As an important country in global crude oil consumption, the impact of its economic conditions on the global crude oil market cannot be ignored. When the U.S. economy is booming, global demand for crude oil naturally increases, thereby driving up international oil prices. However, high oil prices may also have a negative impact on the U.S. economy.

In addition, a sudden factor leading to the rise in oil prices is war. Compare the Iran-Iraq War in the late 1970s and the Gulf War in the early 1990s. The latter led to a sharp rise in oil prices in the short term, but then OPEC significantly increased production to make up for the 3 million barrels per day gap in the oil market after Iraq was imposed economic sanctions. , which shows that OPEC plays a decisive role in international oil prices.

Therefore, when doing investment analysis, wb emphasizes that we cannot mechanically judge market trends based on the inherent negative correlation between the U.S. index and crude oil, nor can we simply use one non-leading indicator to predict another. Relevant indicators. They provide guidance and planning assistance 24 hours a day to better grasp market trends.
