Generally, there is no US dollar interest rate hike, only the Federal Reserve raises interest rates, and the US dollar can only appreciate and depreciate. Fed's interest rate hike is not good for commodities. The Fed's interest rate hike means that the US economy is strong, which will cause a large number of global currencies to flow into the US. Investors can invest in the US market in many ways, which will lead to the rise of the US dollar and the decline of some commodities, precious metals and foreign exchange markets denominated in US dollars.

The Fed's interest rate hike is also bad for the stock market, which will cause certain fluctuations in the RMB exchange rate and increase China's export expectations.

First, the price fluctuates greatly. Only when commodity prices fluctuate greatly, traders who intend to avoid price risks need to use forward prices to determine prices first. For example, some commodities are subject to monopoly prices or planned prices, and the prices are basically unchanged. There is no need for commodity operators to use futures trading to avoid price risks or lock in costs.

Second, the supply and demand are large. The function of the futures market is based on the extensive participation of both the supply and demand sides of commodities. Only goods with large spot supply and demand can fully compete in a wide range and form authoritative prices.

Third, it is easy to classify and standardize. The quality standard of the delivered goods is stipulated in the futures contract in advance. Therefore, futures varieties must be commodities with stable quality, otherwise, it will be difficult to standardize.

Fourth, it is convenient for storage and transportation. Commodity futures are generally long-term delivery commodities, which requires these commodities to be easy to store, not easy to deteriorate and convenient to transport, so as to ensure the smooth delivery of futures.

Commodities also have five characteristics:

1. Lots of supply and demand

2. Country of origin

3. Raw materials

4. National unified price limit

5. Affect the national economy and people's livelihood

Commodities can be designed as futures, and options can be traded as financial instruments, which can better realize price discovery and avoid price risks. Because commodities are mostly industrial bases and at the forefront, the changes in futures and spot prices reflecting their supply and demand will directly affect the entire economic system. For example, rising copper prices will increase the production costs of electronics, construction and power industries, while rising oil prices will lead to rising prices of chemical products and push up the prices and supply of other energy sources such as coal and alternative energy. Investors, especially those who invest in related industries, should pay close attention to the supply and demand of commodities and price changes.
