The United States is the world's largest economy, and the Federal Reserve's bank interest rates and monetary policies have an impact on global commodities. But for crude oil, the impact will not be particularly large.

The most important data is the EIA crude oil inventory data in the United States, which directly reflects the global supply and demand of crude oil. Generally, the market will be larger after the data is released.

Another factor that affects the fluctuation of crude oil is Opec. Opec is an organization of major oil-producing countries. More than 70% of the world's crude oil is mined and sold by them. It is one of the absolute factors affecting global oil prices. Changes in production have a great impact on global oil prices. For example, the United States' extensive use of shale oil technology some time ago caused oil prices to plummet. The Opec meeting announced that it would not cut production, and oil prices immediately stopped the decline and began to rebound.
