[China Securities Association investigates the situation of upside-down brokerage commission rates for new and old customers and low-priced and disorderly competition] On September 7, reporters learned that the China Securities Association is conducting a thorough investigation on the securities trading commission service model for brokerage investors, and the results will be used as a policy reference for the optimization of the commission system. This time, we focused on identifying industry pain points such as inverted rates for new and old customers, disorderly competition at low prices, and continuing declines in commission rates. We also solicited opinions on core institutional issues such as the minimum charge rule of 5 yuan for a single transaction. It is understood that the current commission complaints are concentrated in four types of scenarios: the gap between the preferential rates for new customers and the high rates for old customers has led to demands for commission refunds; insufficient notification of rates during the account opening process and opaque commission listings at the transaction end; difficulty in handling commission applications; and customer sensitivity to commissions due to amplified losses due to market fluctuations. This survey will count the magnitude and proportion of complaints across all channels, explore the existing response strategies of securities firms, and simultaneously solicit industry plans for optimizing the rate notification mechanism and standardizing pricing behavior.
