After investigating the whole incident, China Banking Regulatory Commission confirmed that China Bank had serious violations, and made an administrative penalty decision on February 5, 65438: fined China Bank and its branch * * * 50 million yuan; Warnings and fines of 500,000 yuan were given to the two general managers before and after the global marketing department of BOC, and warnings and fines of 400,000 yuan were given to the relevant deputy general managers and senior traders of the global marketing department of BOC. How much loss should BOC crude oil treasure have caused in this incident? Then let's review this incident. On the evening of April 20th, the US crude oil 2005 contract of BOC had a negative settlement price, and some customers of BOC not only lost the principal, but also paid the deposit to BOC. At that time, some media said that the total loss of BOC crude oil treasure customers was about 4.4 billion US dollars, or about 30 billion yuan. However, some professionals believe that the data is wrong, there is a negative price in crude oil futures, and customers who do more crude oil do suffer a big loss, but the scale is far from 30 billion. Moreover, some short-selling customers made a lot of money. So in this case, the overall loss is not a huge number.
