(1) The state's supervision of the futures market, especially the treasury bond futures market, is not strong enough, and there is no computer alarm system and automatic risk control mechanism.

(2) Some important national economic policies (such as 327 preferential policies, etc.). ) was decided and announced too slowly. If it was clear from the beginning, there would never be so many people shorting this low price. This also invisibly gives the empty side an illusion.

(3) The stock exchange has no mechanism and computer equipment for timely alarming and restricting emergency liquidation, no monitoring and auditing means for company positions and borrowing other people's seats, and no emergency measures for sudden price changes caused by policy changes.

(4) Comrades in some large and medium-sized institutions in the air side do not study macroeconomics, and they often make mistakes in forecasting the increase in subsidy rate caused by inflation.

(5) Some major institutions always want to use the mixed settlement system of the Shanghai Treasury futures market to forcibly sell the so-called "junk treasury bonds" issued by 1995 to many institutions and retail investors through short selling, so as to issue new treasury bonds and make profits for themselves.
