The money invested by investors in the fund is entrusted to custodian institutions such as banks or brokers. The fund company is only responsible for the operation and management of fund investment, and is supervised by the custodian bank. Fund companies have no right to use it at will. The fund manager will not directly contact the funds during the investment operation, but will issue trading instructions, and the custodian bank will complete the transfer of funds. In this way, the separation of fund managers and funds is realized, and there is no misappropriation risk. The fund custodian bank will also supervise the source and destination of funds, verify the authenticity of project funds and supervise the use of funds.
