Fund supervision is common in commercial housing transactions, especially in pre-sale housing and second-hand housing. Banks are third parties other than sellers (developers, real estate agents, etc.). ) and property buyers (property buyers), who have the responsibility of "supervising" the use of funds. The use of the Seller's funds must conform to the conditions bound by the fund supervision contract and the policies of the housing management department. The general contact department is the Retail Banking Department (Personal Finance Department). This kind of business does not need special approval from the regulatory authorities.

On the other hand, asset custody mainly performs the duties of asset custody, fund settlement, asset evaluation, accounting, investment supervision and information disclosure for entrusted assets, including enterprise annuities, investment funds, social security funds, wealth management products, trust assets, insurance funds and QFII assets. The general trustee is Party A, and the trustee (bank) is Party B. Large state-owned commercial banks and many joint-stock commercial banks have set up asset custody departments to take charge of this kind of business, but they also need the cooperation of business departments (companies and peers). This kind of business needs the approval of banking supervision and securities supervision departments.

In addition, there is a similar one: third-party depository. Mainly in cooperation with securities companies, securities companies keep investors' investment securities, and banks keep investors' settlement funds, which belong to investors and cannot be used by brokers. In case the broker goes bankrupt, the bank can also guarantee the funds. This business involves the same trading department and needs the approval of the securities regulatory department.
