[China Securities Association is conducting a thorough investigation on the trading commission situation of securities firms and whether it is "free for five years" to welcome the industry assessment] On September 7, the reporter learned that the China Securities Association is conducting a thorough investigation on the securities trading commission service model for investors of securities firms, and the results will be used as a policy reference for the optimization of the commission system. In this survey, the minimum fee rule of 5 yuan for a single transaction, which has been implemented for many years, became the core argumentation issue. The survey solicited securities firms’ attitudes toward this system, including “maintaining the same, moderately reducing it, or completely canceling it.” The China Securities Association also put forward the consideration of relevant plans, maintaining the focus on guarding the bottom line of costs and preventing vicious price wars; the downward adjustment is directed to adapting to the current online transaction costs and reducing the burden on small and medium-sized investors; the cancellation focuses on eliminating the distortion of nominal rates and compressing the gray operating space of the "Five Free".
