Business types of bank-certificate cooperation

The business types of bank-certificate cooperation also tend to be the same, which can be divided into the following categories:

1. Account Management: account opening, account sales, change, and query

2. Funds Transfer: transfer, transfer, correction, and query

3. Freeze funds: Freeze, unfreeze, dash, and query

4. Liquidation and reconciliation: general ledger, details, liquidation, and query

For each business type, the operational procedures of different banks and securities companies are still quite different. The same business may have multiple application methods: Brokerage initiation, bank initiation, and mutual initiation, however, information exchange content for each business is similar.

The Structure Design of this standard is based on ISO15022, and draws on the experience of many mature international products and systems. As the most influential International Organization for Standardization, the International Organization for Standardization (ISO) has developed multiple standards for multiple industries. ISO15022 is the latest standard for data standardization. It mainly defines the meaning of each field in the information to be exchanged during securities transactions, what should each piece of information in a transaction contain. ISO15022 complies with the standards acquisition principle of our country after the WTO entry and the opening needs of China's financial industry, and is conducive to mutually beneficial cooperation among various subjects in the financial industry; the development direction of ISO15022 is consistent with that of the Bank of China and the securities industry, and can meet the needs of most businesses.

In the securities industry, FIX is the most important standard, but it has its limitations. In the three fields of transactions, the FIX protocol occupies an absolute position in the two fields before and during the transaction. In the post-transaction fields, according to the STP implementation model, the flow of funds between the transaction parties mostly occurs in different banking systems, which is precisely the application field of SWIFT/ISO15022. In particular, ISO15022 has already applied a wide range of protocols in 192 countries and 7000 financial institutions.

1. Object-oriented Design

Currently, there are two main data exchange modes for the bank card transfer business in China: file exchange, Packet Exchange, and mainstream international data exchange protocols (such as fix and iso15022) both are Packet Exchange methods. This standard also uses Packet Exchange methods. The main design idea is to separate the business elements from their actual forms and ensure that all business information (messages) is expressed in the same way.

(1) data field ):

First, the information elements are abstracted into data fields;

(2) data domain:

The messageset is the only element that constitutes an information block. The data field consists of data fields according to the degree of affinity. It includes two types: universal data domains (such as the transaction location, time, currency, account, and other general commercial elements) and non-universal data domains, which can be reused.

(3) Message Block ):

The data field is composed of information blocks according to the corresponding transaction type. It contains common information blocks and business information blocks. The general information block should be referenced by each information body. It is a required information block. Each information body should contain the block start mark, the sender's reference information, the information function, the sending time, the transaction type, and the block end mark.

(4) Message Type ):

An information body consists of one or more information blocks. Each information body corresponds to a transaction type. This standard is also called a data packet (such as table 1 ).

2. Information body structure and design

The information body design adopts the iso15022mt5xx series information package design method. Each information body consists of many parallel or nested small information bodies. The structure of each information body is 2.

3. Business Definition

The bank certificate transfer is divided into the following transaction types. Each transaction type corresponds to a type of information body. The package name and package encoding of each information body are shown in table 2.

(1) authentication (mt001)

Authentication includes two business types: sign-in and sign-out.

(2) Account Opening (MT002)

An account is used to establish the correspondence between a Securities Fund account and a bank account, including opening a fund account or a stock account and establishing a corresponding relationship.

(3) Account Management (MT003)

Account Management includes: Sales, freeze, unfreeze, and other business types.

(4) card swap Management (MT004)

Card swap management includes changing bank cards, changing securities cards, and other business types.

(5) investor data modification (MT005)

Investor Information Modification includes modifying personal information, modifying agent information, modifying institution information, modifying Securities Investors' information, and modifying bank investors' information.

(6) transfer request (MT006)

A transfer request is used to deliver a fund transfer instruction. A transfer request is sent directly or through an intermediary institution to the financial institution where the beneficiary investor is located.

The transfer request is used for net payment. It cannot be used as a check, remittance, or step-by-step transaction.

(7) transfer receipt (MT 007)

The transfer receipt is used as a response to the transfer MT 006.

(8) reconciliation information (MT008)

Reconciliation is used for detailed reconciliation or summary reconciliation of requests. Reconciliation can be issued by the bank or by the securities end. After receiving MT008, the receiving Party shall return the reconciliation receipt MT009 (detailed reconciliation and summary reconciliation ).

(9) reconciliation receipt (MT 009)

MT009 is used to feedback the Reconciliation Request (MT008) and send the details and total of the specified account to the sender.

(10) Query Information (mt010)

The query includes querying fund information, basic investor information, and querying fund generation flow.

(11) query receipt (mt011)

It is used to respond to mt010 queries, including: Answering fund information, answering basic investor information, answering fund flow, answering market information, answering stock balance and other business types.

Conclusion

In the financial battlefield, the curtain of competition has been opened. With the exploration of our standardization work, the banking and card cooperation business will inevitably shift from standard to orderly. In order to effectively improve the market operation efficiency and build the core competitiveness of the capital market, only through the promotion of market participants and the implementation of standard propaganda can be implemented. We believe that we can rely on standardization to establish rules to promote market development and technological progress. In the face of mixed industry competition, we can ask, who is the hero in the world, with the sword in hand.
