Why should we vigorously develop the intermediary business of banks

This question belongs to a research topic. I'll be brief, and please advise me if I'm inappropriate.

One is that after the marketization of interest rates, banks traditionally rely on the deposit and loan spreads narrowed in both directions, profitability has been gradually compressed, banks have to rely on the development of investment banking and other intermediate business to increase profits.

The second is that the intermediate business itself is characterized by low cost and high profit contribution rate.

Thirdly, under the implementation of Basel III regulatory requirements, the banking industry must take the road of capital intensification, achieve growth through connotative rather than episodic means, and try to make good use of capital. It has to be more diversified and innovative in terms of products, which prompts banks to vigorously develop intermediate business.

Of course, from a micro point of view, vigorously developing intermediate business can also improve customer satisfaction and enhance customer stickiness.

In short, the domestic banking industry vigorously develop intermediate business there are both external and internal reasons.
