Generally speaking, for example, politics and policies will have an impact on the macro-economy, so stock index futures, as the vane of the overall economy, will always be most directly affected. The quality of macro-economy will affect the supply and demand of micro-industrial chain, and then affect commodity futures prices.

What is special is that various influences are more direct, such as monetary policy, which directly affects the measurement of commodity value. For example, geopolitics, the situation in the Middle East directly affects the international crude oil supply and so on. There are so many, I don't want to list them all. I suggest that there are various cases in the analysis report of the futures market.
