According to relevant information, Guan Jinsheng's 654.38+046 billion yuan was obtained in the securities market. The reason is that1February 23, 1995, the Ministry of Finance issued an announcement: 327 national debt will be paid at 148.50 yuan, and the short judgment is completely wrong. China Economic Cooperation led the bulls to do more and pushed up the price. At this time, the book loss of IWC was 5.6 billion yuan. In order to avoid a big loss, Guan Jinsheng made a crazy decision: overdraft short. In the last eight minutes, we first shorted 500,000 yuan to suppress the national debt to the vicinity of 150 yuan, and finally shorted 7.3 million yuan to hit the price to 147.4 yuan. After the close, IWC changed from a floating loss of 5.6 billion to a floating profit of 4.2 billion, while CDB changed to a floating loss of 4 billion. The face value of 7.3 million lots was 654.38+046 billion yuan, while the total value of 327 national debt at that time was only over 30 billion yuan. As Guan Jinsheng's behavior has exceeded the bottom line of high-level tolerance, at 9 o'clock that night, the Shanghai Stock Exchange directly declared the last 8 minutes of trading invalid, and the closing price was 15 1.3 yuan. In the end, the darkest day in the history of CITIC Construction Investment ended with a loss of 6 billion yuan, the arrest of Guan Jinsheng, the resignation of the head of the Shanghai Stock Exchange and the closure of the treasury bond futures market.
