With the continuous decline of foreign crude oil, the domestic attention to crude oil is gradually increasing. So for investors, is the overseas crude oil transaction we usually see legal? What are the specific problems? Is overseas crude oil trading legal? The formal channels of overseas crude oil trading are legal, mainly regulated by foreign regulatory laws. However, in China, transactions related to overseas crude oil are actually illegal, not only because the relevant investment products in the market are mixed, but also because the relevant companies are not qualified enough, and for most people, many rules and regulations of overseas crude oil itself are not well understood. In this regard, overseas crude oil transactions vary from person to person, and it is legal for us to choose formal channels to operate. Although overseas crude oil is ostensibly trading some crude oil futures in the United States, it is essential to consider the operational risks of related companies, such as the crude oil treasure incident of China Bank. In addition, overseas crude oil is opened overseas, so trading all the ability to change the trading rules, that is, crude oil futures in May showed negative oil prices. In this regard, even if formal enterprises participating in legal compliance invest in overseas crude oil transactions, they should also consider the impact of other things on the market. In this regard, overseas crude oil trading needs to be more careful.
