Third-party custody, an account can only sign up for one bank.

Introduction:

"Third-party depository" is a business provided by commercial banks, which is often used in securities, futures, real estate and other trading activities. Taking the third-party depository in securities trading as an example, it means that according to the requirements of laws and regulations, the depository bank is entrusted to take charge of the deposit and withdrawal of customers' funds and the delivery of funds, and the securities trading operation remains unchanged. Securities trading settlement funds of clients of securities companies shall be deposited by banks.

Third-party depository follows the principle of "brokers manage securities and banks manage funds", and strictly separates investors' securities accounts from securities margin accounts. Under the third-party depository mode, securities brokerage companies no longer provide customers with access services for transaction settlement funds, but are only responsible for customer securities transactions, share management and clearing and settlement. Depository banks are responsible for managing customers' transaction settlement fund management accounts and customers' transaction settlement fund summary accounts, providing customers with transaction settlement fund access services and providing settlement support for securities brokerage companies to complete enterprise fund settlement with registered settlement companies and foreign exchange recipients. The bank is responsible for completing the transfer of clearing funds between the investor's special deposit account and the brokerage bank settlement account, and handing over the brokerage clearing and settlement procedures to the bank, which will complete them on its behalf.
