Regular spot silver is legal, and the funds of spot silver are directly linked to the five major state-owned banks. This means that the CBRC acquiesced in the existence of these investments and also reflected the feasibility of spot silver investment.

If spot investment is illegal, then the country will definitely crack down on all spot crude oil exchanges, but now there are more and more exchanges, which shows the legitimacy of spot crude oil. Of course, there are lawless elements in any industry. At present, there are indeed many illegal platforms, and the state's pressure on illegal platforms has not been relaxed. It is believed that the domestic crude oil market will become more and more standardized under the suppression of the state.
