Description

  The present invention relates to a custody support system that supports a custodian operation for trading securities, and more particularly to a custody support system that controls balance allocation.

  In normal non-resident transactions, for example, when an overseas investor wants to buy or sell stocks of a Japanese company, he / she asks a global custodian who conducts storage operations for securities in multiple countries at once to request stock trading. Do. The global custodian then makes a settlement order via the SWIFT (The Society for Worldwide Interbank Financial Tele-communication) system to the sub-custodian who manages and manages the securities in Japan after making a trade agreement with an overseas securities company. Send data. When the sub-custodian receives the settlement instruction data from the global custodian, the sub-custodian transmits a collation message to the settlement collation system of the securities custody transfer mechanism. On the other hand, similarly, an overseas securities company that has been contracted with a global custodian sends a settlement instruction to a domestic securities company. Based on the settlement instruction data of the overseas securities company, the domestic securities company transmits a collation message to the settlement collation system of the Japan Securities Depository Center. When the verification messages of the sub-custodian and the domestic securities company match in the settlement verification system, the securities are delivered by account transfer (for example, Patent Document 1).

JP 2002-245250 A

  By the way, depending on the overseas customers of sub-custodians who manage and manage securities in Japan (which plays the same role as the above-mentioned global custodians) and settlement partners, the account balance may or may not be abundant, In many cases, they sell and sell the received securities as they are. There are many variations such as chaining and looping in selling transactions. In the case of a type in which overseas customers and domestic settlement partners sell securities purchased without holding a large balance, settlement may be delayed unless appropriate provisional control is performed in the sub-custodian.

  FIG. 7 is a diagram showing the simplest example of a problem relating to provisions that occur in conventional securities transactions. For example, it is assumed that a Japanese sub-custodian receives an instruction as shown in FIG. 7A from an overseas customer. In other words, it is assumed that an overseas customer buys and sells 1000 shares between a settlement partner A and a settlement partner B, which are domestic securities companies. FIG. 7B shows a case where these transactions are processed in an optimal order. Here, it is assumed that the initial balance of the custody account of the overseas customer and the settlement partner A is “0”, and the initial balance of the custody account of the settlement partner B is “10000”. In such a situation, as shown in FIG. 7 (b), when transactions are performed in order from transaction numbers (1) to (4), the overseas customer makes contact with settlement partner A and settlement partner B from one side. Since the purchased stock is sold to the other side, even if the initial balance of its own custody account is “0”, the transaction proceeds smoothly.

  However, as shown in FIG. 7 (c), when processed in the order of transactions (1), (4), (3), (2), settlement partner A holds the balance of the same issue. Therefore, it is necessary to make a settlement after borrowing from other securities companies. In this case, even if the transaction cannot be settled and the sale-and-sell transaction cannot be settled, or even if it can be borrowed, in order to wait for the processing of the borrowed stock before the transaction (3), There is a problem of becoming. In addition, a procedure for returning the borrowed stock is necessary at the end, and a borrowing fee is also incurred.

  Moreover, if the overseas customer's initial balance is “0” (or if it is very small), of course, if the buying transaction from the settlement partner is not preceded, the selling transaction is performed without borrowing. I can't do it.

  Conventionally, the order of a plurality of transactions is controlled within the sub-custodian so that the transaction order as shown in FIG. However, determining the order of a large number of transactions so as not to cause inconvenience such as inability to settle and stock borrowing is an operation that requires a lot of time and labor.

  Accordingly, an object of the present invention is to provide a custody support system that performs appropriate balance allocation control in order to smoothly settle a non-resident's securities transaction in order to solve the above-described problems.

  In order to solve the above-described problem, an aspect of the present invention provides an allocation control process in a securities transaction between a securities trader who is a non-resident and a settlement partner which is a counterparty of the securities trade of the securities trader. A settlement verification detail storage unit that receives and holds securities transaction instruction data relating to the custody account of the securities trader, and the vibration of the settlement partner from the custody account ( The first delivery transaction data, which is the delivery transaction data of the securities to the first account, which is an account on the securities storage and transfer system), is extracted from the instruction data, and the settlement partner different from the one settlement partner Receiving transaction data of the subject securities that are securities of the same brand and same delivery date as the securities from the second account, which is an account for treasury, to the custody account Extracting certain first received transaction data, grouping both as a first group, and receiving second received transaction data that is received transaction data of the target securities from the first account to the custody account, Second delivery transaction data that is extracted from the instruction data and is delivery transaction data of the target securities from the custody account to a third account, which is an account of a settlement partner different from the one settlement partner Are extracted and grouped together as a second group, stored in the associated group information storage unit, and when receiving the target securities to the custody account at the time of settlement, A custody support system comprising a linking execution unit that executes a settlement process for transaction data and delivery transaction data grouped.

  In another aspect of the present invention, a settlement verification details storage unit, a tied group information storage unit, and a tied execution unit are provided, and the securities trader who is a non-resident and the securities trader's valuables are provided. An allocation control method in a securities transaction executed by a custody support system that performs an allocation control process in a securities transaction with a settlement partner that is a counterpart of a securities transaction, wherein the linking execution unit includes a custody account of the securities trader Receiving the instruction data of the securities transaction related to the transaction via the network and storing it in the settlement verification storage unit; and the linking execution unit from the custody account The first delivery transaction data, which is the delivery transaction data of the securities to the first account, which is an account on the system) is extracted from the instruction data, and the one First transaction receiving data of a target securities which are securities of the same brand and same delivery date as the securities from the second account, which is an account on the vibration of a settlement partner different from the settlement partner, to the custody account Extracting the received transaction data of the first group and grouping both as a first group, and the linking execution unit is a second transaction data that is received transaction data of the target securities from the first account to the custody account Receiving transaction data is extracted from the instruction data, and is the transaction transaction data of the target securities from the custody account to a third account, which is a settlement account of a settlement partner different from the one settlement partner Extracting the second delivery transaction data, grouping both as a second group, and the linking execution unit includes the first group and the first group When the transaction data grouped into the group is stored in the association group information storage unit, and the association execution unit executes the receipt processing of the target securities to the custody account at the time of settlement, And a step of executing settlement processing for the received transaction data indicating the reception processing and the grouped delivery transaction data.

  According to another aspect of the present invention, a computer executes an allocation control process in a securities transaction between a non-resident securities trader and a settlement partner of the securities trader. An allocation control program, wherein the computer receives, via a network, instruction data of securities transactions related to the custody account of the securities trader and stores the data in the settlement verification details storage unit; and the custody account From the instruction data, the first delivery transaction data, which is the delivery transaction data of the securities to the first account that is an account on the one of the settlement partner's treasury (stock storage transfer system), The same stock and the same stock as the securities from the second account, which is an account for vibration of the settlement partner different from the one settlement partner, to the custody account Extracting the first received transaction data, which is the received transaction data of the target securities that are the securities in Japan, and grouping them together as a first group; and the process from the first account to the custody account The second account transaction data, which is the receipt transaction data of the subject securities, is extracted from the instruction data, and from the custody account, a third account that is an account on the vibration settlement of a settlement partner different from the one settlement partner Extracting the second delivery transaction data, which is the delivery transaction data of the target securities to the group, and grouping them as a second group, and grouping them into the first group and the second group The transaction data stored in the associated group information storage unit, and at the time of settlement, the target securities are received into the custody account. If a provision control program provision control program which is a program for executing the processing including a process of executing the settlement processing for receiving transaction data and grouped delivery transaction data indicating the receiving process.

  For example, in the example of FIG. 7, a purchase transaction of transaction number (1) in which a custody account of an overseas customer receives a security from settlement partner B and a sale transaction of transaction number (2) in which the security is delivered to settlement partner A Group into one group (Group 1). Similarly, purchase transactions (transaction number (3)) and sales transactions (transaction number (4)) for overseas customers are grouped into one group (group 2). By grouping securities transaction data in this way, it is possible to avoid the occurrence of borrowed stock and the like and to smoothly settle securities transactions.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings referred to in the following description, the same parts as those in the other drawings are denoted by the same reference numerals.

(Outline of automatic linking method in custody support system)
Hereinafter, an outline of an automatic association method (allocation control) in the custody support system according to the present embodiment will be described. As described above, the automatic linking method according to the present embodiment, for a custody account (for example, an overseas customer of a Japanese sub-custodian in Japan) that is a target of automatic linking of the present embodiment, By grouping buying and selling transactions between a specific partner) and other settlement partners, smooth settlement is possible.

(Example of automatic pegging conditions)
FIG. 1 is a diagram illustrating an example of conditions for automatic pegging. There are three conditions for automatic tying. In the case of custody accounts targeted for automatic pegging according to the present embodiment, in the case of pegging with a specific partner and the other partner buying and selling one-to-one (condition 1), buying and selling will be one-to-N. In the case of pegging (condition 2), the case of pegging where buying and selling are N-to-one (condition 3). In the example of FIG. 7, the buy transaction and the sell transaction grouped with respect to a specific custody account (overseas customer's custody account) are one-to-one (that is, (1), (2), (3) And (4)), grouped buy and sell transactions may be one-to-N or N-to-one.

  In the conditions 1 to 3 shown in FIG. 1, the purchase transaction and the sale transaction grouped for the custody account to be automatically linked are “VALUE-DATE” (delivery date), brand, account, and vibration control (securities storage). It is a condition that the classification account on the transfer system) and the determination of the public offering / normal transaction are the same (item numbers 1 to 4). In addition, the purchase transaction and the sale transaction to be grouped are required to have different buyers and sellers (item number 5).

  As for the condition of item No. 6, if buy and sell are 1 to 1 (condition 1), the quantity / face value of buy and sell are the same, and buy and sell are 1 to N or N to 1 ( In the case of the condition 2 and the condition 3), it is assumed that the quantity / face value of one transaction is the same as the combined quantity / face value of N transactions.

  In the case of actually performing automatic pegging at the time of settlement verification, first, a plurality of sales transactions of an account for which automatic pegging is executed are searched for those that match these three conditions. Then, the combination of buying and selling is grouped, and at the stage where buying is established, the transaction is established by allocating selling of the group.

(Specific example of automatic pegging)
FIG. 2 shows an example of the linking result when automatic linking is executed under the conditions shown in FIG. In FIG. 2, the “when linking” column and the “when re-linking or settlement” column show examples of linking results. Further, the “correlation condition” indicates which condition in FIG. 1 is applied when automatic linking is performed in each linking example. The example of linking shown in the “When linking” column is an example of automatic linking performed at the time of settlement verification. The example of linking shown in the “When linking again or at the time of settlement” An example of linking is shown when linking is performed again.

  “Counter” in FIG. 2 indicates a trading partner of a specific custody account (overseas customer in the example of FIG. 7) targeted for allocation control (automatic pegging). “Specific partner” is, for example, a settlement partner A “Other partner 1” or the like indicates a partner other than the settlement partner A (settlement partner B or the like), for example.

  Pattern 1 is a specific example of automatic pegging for smoothly performing the same transaction as in FIG. In pattern 1, receipt (buy) from other partner 1 and delivery (sale) to a specific partner are linked as one group (group 1) (thus, as a result, other partner 1 Will be used for delivery to a specific partner). In addition, the receipt from the specific partner and the delivery to the other partner are linked as one group (Group 2) (Thus, as a result, what is received from the specific partner is sent to the other partner Will be devoted to delivery). When a payment is received from the other party 1 at the time of settlement, the group 2 is traded after being delivered to a specific party (group 1) grouped with the other party 1 (That is, as a result, payment is performed in the order of “order” 1 to 4 at the time of payment). As a result, the delivery of the number (4) is executed when the receipt of the number (3) is established, and it is possible to prevent a process such as borrowing from occurring.

  Pattern 1 ′ is a case in which the same pegging as pattern 1 is performed, but when receipt from a specific partner (number (3) at the time of settlement verification) is established first at the time of settlement, it is grouped with this (group 2) Deliver to the other party 1 (number (4) at the time of settlement verification) first, and then conduct group 1 transaction later. As a result, it is possible to prevent the delivery of the number (2) from being executed after the receipt of the number (3) is established at the time of settlement verification.

  It should be noted that, in the custody support system according to the present embodiment, association and provisioning are performed by grouping, and ranking is not performed for each group in the system. That is, it is only grouped at the time of collation, and after that, depending on the receipt timing at the time of settlement, the result is the above pattern 1 or pattern 1 '.

  Pattern 2 is an example in the case of buy> sell. The receipt of the number (3) and the delivery of the number (4) are grouped because the number of shares is the same (group 1). Further, the receipt of the number (1) and the delivery of the number (2) are receipt (buy)> delivery (sale). In this case, whether there is an excess or deficiency in the instructions is confirmed with the overseas customer subject to the provision control, and if there is a deficiency, automatic association is performed after additionally receiving the deficient instructions. Even if buy> sell, tuning to automatically set to group 2 is possible.

  Pattern 2 'is an example when automatic linking is performed after receiving a shortage of instructions in pattern 2. With regard to receipt of number (1) and delivery of number (2) in pattern 2, for example, after confirming to the trading partner whether there is any excess or deficiency in the instructions, delivery of “100 shares” to other partner 1 When the shortage instruction is received, automatic linking is performed again at the time of account transfer, and the transactions of numbers (1) and (2) and the delivery to the other destination 1 additionally received are grouped. Note that in this case, the receipt (buy) and the delivery (sale) are 1 to N, and automatic association is performed by applying condition 2 in FIG.

  Pattern 3 is an example of pegging when buying and selling are N to 1. At the time of linking, receipt from the other party 1, receipt from the other party 2, and delivery to the specific party are grouped based on the condition 3. After that, when the account transfer is partly received, for example, if “100 shares” cannot be received due to a shortage of securities at the other party 2, only “150 shares” from the other party 1 can be delivered to the specified party. In addition, the initial delivery “250 shares” to the specified partner is divided into “150 shares” and “100 shares”, each of which is received “150 shares” from the other party 1 and received from the other party 2. Link with “100 shares”.

  Pattern 4 is a specific example in the case where buy and sell are linked by 1 to N (condition 2) or N to 1 (condition 3). According to the automatic association of the pattern 4, it is possible to prevent the delivery of the number (4) from being executed after the receipt of the number (1) is established.

  Pattern 4 ′ is also a pattern in which buy and sell are linked 1 to N (condition 2) or N to 1 (condition 3) at the time of settlement. When the receipt (number (3) at the time of settlement verification) precedes, the group 2 transaction linked to this is performed first, and the group 1 transaction is performed later. As a result, it is possible to prevent the delivery of the number (4) from being executed after the receipt of the number (1) at the time of settlement verification is established.

  Even if the combination is outside the automatic association rules, if manual association is performed, the allocation is automatically processed according to the grouping.

(Configuration of custody support system)
FIG. 3 is a block diagram showing an example of the software configuration of the custody support system according to the present embodiment. The custody support system includes a pegging execution component 100 that executes automatic pegging, a plurality of libraries 110 to 113, and a plurality of database (DB) tables 120 to 122. Further, the custody support system shown in FIG. 3 is connected to a SWIFT system (not shown) and a securities custody transfer system of a securities custody transfer mechanism via networks. Furthermore, the custody support system of the present embodiment is a system that is assumed to be installed in a financial institution or the like that is a sub-custodian in Japan.

  As shown in FIG. 4, the collation control information table 121 includes an account code of an account to be automatically linked (corresponding to the overseas customer's custody account in FIG. 7), product classification, destination code (in FIG. 2). Is a table that holds a part of the conditions for automatic linking. Further, the settlement verification detail table 120 is a table that holds the instruction data transmitted from the SWIFT system (FIG. 4). Further, the pegging group information table 122 is a table that holds the result of automatic pegging, and is a table that holds the result of automatic pegging as shown in FIG. Further, the contents of the association group information table 122 are used for control at the time of settlement verification, and further, when necessary, at the time of account transfer.

  FIG. 5 is a sequence diagram showing the overall flow of processing in the custody support system according to the present embodiment. As shown in FIG. 5, for example, when the association execution component 100 is activated by demand or automatic activation batch processing from the WEB-based instruction screen (user operation screen) of the custody support system (step S102), the association execution component 100 refers to the settlement collation details table 120 and the collation control information table 121 (step S104, step S106) and uses the linked group information table 122 (step S108) while using each of the libraries 110 to 113 as necessary. ) To extract transaction data not yet registered. For transactions that can be automatically associated, association group information is created and stored in the association group information table 122. (Step S110).

In the present embodiment, transactions that can be automatically linked are assumed to be the following combinations of transactions.
(1) Sell: Buy = 1: N grouping condition (a) When the sale transaction of account code + product category + destination code registered in the collation control information table 121 is only one transaction (one transaction Judgment is based on the fact that the following items do not have the same transaction)
・ Account code ・ Division account code ・ VALUE-DATE
・ Brand master code ・ Transaction type (b) When the total amount / face value of buying transactions that match the following conditions matches the quantity / face value of (a) ・ Account code (same)
・ Division account code (same)
・ VALUE-DATE (same)
-Brand master code (same)
-Transaction type (same)
・ Destination code (destination code different from (A))
(2) Buy: Sell = 1: N grouping condition (a) When the purchase of the account code + product classification + destination code registered in the collation control information table 121 is only one transaction (one transaction Judgment is based on the fact that the following items do not have the same transaction)
・ Account code ・ Division account code ・ VALUE-DATE
・ Brand master code ・ Transaction type (b) When the sum of quantity / face value of sales transactions that meet the following conditions matches the quantity / face value of (a) ・ Account code (same)
・ Division account code (same)
・ VALUE-DATE (same)
-Brand master code (same)
-Transaction type (same)
・ Destination code (destination code different from (A))

  For example, in the example of the collation control information table 120 and the settlement collation details table 120 shown in FIG. 4, the transaction data matching the above (1) (a) is “DATA1”, and the above (1) (I The transaction data matching “)” is “DATA2 to DATA3”. Since the total value of the quantity / face value of “DATA2 to DATA3” is “3000”, which is the same as “DATA1”, the linking execution component 100 links them as the same group. Note that the transaction data “DATA4 to DATA10” does not match the conditions (a) and (b) above (the shaded portion), and is therefore not subject to automatic linking.

  The custody support system 1 according to the present embodiment described above includes a general computer device such as a memory (not shown) such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a storage device such as a hard disk, and a network interface. It is possible to implement | achieve by the structure similar to this structure. Specifically, for example, the linking execution component 100, the various libraries 110 to 113, and the DB tables 120 to 122 shown in FIG. 3 are stored in a storage device such as a hard disk, and the CPU executes these programs and data. Is automatically read out from the storage device to a work area such as a RAM, or the sequencer logic is custom designed in, for example, an FPGA (Field Programmable Gate Array). Executed.

  As described above, in the custody support system according to the present embodiment, transaction data is grouped at the time of settlement verification, and when the receipt and settlement of securities for the custody account that is the target of provision control is completed, Deliver settlement for delivery transaction data grouped with receipt transactions. Thereafter, settlement processing of another group different from the group of these transaction data is executed. Note that the specific contents of the payment process are known techniques as disclosed in, for example, Patent Document 1, and therefore the details are omitted here.

(Processing flow)
FIG. 6 is a flowchart showing an example of a process flow of the custody support system according to the present embodiment.

  First, business initial processing is performed (step S202), and a local connection in network communication is acquired (step S204).

  The pegging execution component 100 reads the pegging conditions from the collation control information table 121 and searches the transaction data to be automatically linked from the settlement verification details table 120 while referring to the pegging group information table 122 to determine “ A list of “sales” transaction data is acquired (step S206). Then, the pegging execution component 100 acquires “buy” transaction data corresponding to the “sale” transaction data in the “sale” transaction data list acquired in step S206 from the settlement verification details table 120 (step S208). Then, it is determined whether the “sale” transaction data and the acquired “buy” transaction data can be grouped (step S210). If grouping is not possible, the process returns to step S208, the next “buy” transaction data is acquired, and the determination of whether grouping is possible (step S210) is repeated.

  If it is determined in step S210 that grouping is possible, the pegging execution component 100 registers a combination of “sale” data and “buy” data in the pegging group information table 122 (step S212).

  Next, the pegging execution component 100 reads the pegging conditions from the matching control information table 121, searches the settlement matching details table 120 for transaction data to be automatically linked, and refers to the pegging group information table 122 to determine whether A list of linked “buy” transaction data is acquired (step S214). Then, the pegging execution component 100 acquires “sell” transaction data corresponding to the “buy” transaction data in the “buy” transaction data list acquired in step S214 from the settlement verification details table 120 (step S216). Then, it is determined whether the “buy” transaction data and the acquired “sell” transaction data can be grouped (step S218). If grouping is not possible, the process returns to step S216, the next “sale” transaction data is acquired, and the determination of whether grouping is possible (step S218) is repeated.

  If it is determined in step S218 that grouping is possible, the pegging execution component 100 registers a combination of “sale” data and “buy” data in the pegging group information table 122 (step S220).

  As described above, according to the custody support system according to the present embodiment, smooth settlement is realized by a simple process of associating purchase transaction data and sale transaction data in non-resident securities transactions. be able to. Moreover, it becomes possible for the person in charge to perform appropriate balance allocation control without spending much time and labor as in the past, which contributes to cost reduction.

  The settlement verification details DB table 120 in the above embodiment corresponds to the “settlement verification details storage unit” of the present invention. The linking group information DB table 122 corresponds to the “linking group information storage unit” of the present invention. The association execution component 100 and hardware such as a CPU that executes the association execution component correspond to the “association execution unit” of the present invention.

  Up to this point, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention may be implemented in various forms within the scope of the technical idea.

  The scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention.
