1. Agency open-end fund business regulates the development of intermediary business of commercial banks. The disorder and vicious competition in the development of intermediary business of commercial banks have seriously restricted its normal and orderly development. With the transformation of commercial banks' operating mechanism and the enhancement of market awareness, intermediary business has become an important field of commercial banks' competition. Various behaviors adopt the strategy of charging little or no fees, such as providing customers with business premises for free, equipping them with computers, and arranging employment. For example, interest rates are not marketized, which leads to "rent-seeking" and unfair competition between banks and enterprises.

2. Acting as an agent for open-end funds and cultivating intermediate business management talents of commercial banks. Intermediary business, especially the emerging intermediary business closely related to capital operation, capital market and money market, is a brand-new field for Chinese commercial banks and has great development space. But any enterprise will inevitably face competition. Intermediate business related to fund management with high profits and relatively dull competition requires high operational skills, theoretical background and advanced professional skills. The lack of new intermediate business management talents is an important factor restricting the development of new intermediate business in China. Talents who are familiar with financial market structure, capital market operation and commercial bank management skills.

3. Agency fund business enriches the content of intermediary business of commercial banks, which is beneficial to commercial banks to better serve customers. The traditional intermediary business of China's commercial banks basically focuses on the aspects related to deposit accounts, such as exchange, settlement, receipt and payment, etc. However, acceptance and letter of guarantee are unlikely to develop greatly from the perspective of risk prevention and lack of market environment and foundation. Relatively speaking, fund custody business is a new intermediate business with relatively small risk and relatively high profit. In the process of fund custody, it involves customer consultation, purchase and redemption transactions, transfer custody, transfer and so on.
