Which expert can talk about the difference between spot silver investment bank custody and depository?

Bank custody: As a third party, the spot bank, on behalf of the interests of the asset owner, is engaged in the custody of the assets under custody, handles the settlement of funds under the name of the assets under custody, conducts accounting and valuation of the assets under custody, supervises the investment operation of managers and collects custody fees.

Bank Depository: The securities trading settlement funds of securities company customers are deposited by the bank, which is responsible for the deposit and withdrawal of customers' funds and the delivery of funds according to the requirements of laws and regulations, and the securities trading operation remains unchanged.

This business follows the principle of "securities management by brokers and funds management by banks", that is, securities management by brokers and funds management by banks, and investors' securities accounts and securities margin accounts are strictly managed separately.
