Summary of the Invention

Problems to be Solved by the Invention

[0004] A new NISA (Nippon Individual Savings Account) system was started in January 2024, and the non-taxable investment framework has been significantly expanded from the current system, such as an increase in the annual investment limit without tax and the elimination of the non-taxable holding period limit. Therefore, an increase in the number of users using the NISA system is expected. However, for users without investment experience, the NISA system is complicated and the hurdle for investment is high. The device of Patent Document 1 can perform rebalancing processing, but does not provide a service to support users who invest using the NISA system.

[0005] An object of the present disclosure is to provide an information processing method and the like that can support users who invest using the NISA system.

Means for Solving the Problems

[0006] An information processing method relating to one aspect of this disclosure involves a computer that determines whether or not to sell financial instruments held by a customer in a tax-exempt account, based on the book value and market value of the said financial instruments. If it is determined that to sell the said financial instruments, the computer performs a process of selling the said financial instruments and purchasing the same or different financial instruments with the funds in the tax-exempt account.

[0009] The information processing method, program, and information processing apparatus of this disclosure will be described in detail below with reference to the drawings illustrating their embodiments.

[0010] This embodiment describes an information processing system that buys and sells financial products held by a customer in an account opened by the customer at a financial institution, based on the customer's request. Financial products in this disclosure include securities such as stocks and bonds, as well as investment trusts. In the information processing system of this embodiment, the customer holds a tax-exempt account (NISA account) for tax-free investments and a regular taxable account, and investment funds deposited by the customer are invested in at least one of the tax-exempt account and the taxable account.

[0011] Figure 1 is an explanatory diagram showing an example of the configuration of an information processing system. The information processing system of this embodiment includes a server 10 managed by an asset management company that provides asset management services for managing customers' investment funds, and customer terminals 20 used by customers who utilize the asset management services provided by the server 10. Each device is communicated with via a network N. The network N may be the Internet or a public telecommunications network, or it may be a LAN (Local Area Network) built within the facility where the server 10 is located.

[0012] Server 10 is an information processing device capable of various information processing and information transmission / reception, and can be a server computer, personal computer, etc. Customer terminal 20 is an information processing device capable of various information processing and information transmission / reception, and can be a smartphone, tablet terminal, personal computer, etc. The customer may be an individual or a corporation. In the information processing system of this embodiment, when Server 10 receives a request from Customer Terminal 20 to execute a deposit process to an account held by the customer (tax-exempt account and taxable account), it executes a deposit process from the account of the financial institution from which the deposit is made to an account managed by the asset management company, according to the content of the received request. As a result, the asset management company receives the deposit of the customer's investment funds into the customer's account that it manages. In addition, Server 10 purchases financial products using the customer's investment funds and executes a process to automatically buy and sell the financial products held by the customer according to the status of the customer's account (for example, the book value and market value of the financial products held in each account). The account managed by the asset management company may be, for example, an account opened at a financial institution with which the asset management company has a partnership, or, if the asset management company is a financial institution, an account opened by the asset management company.

[0013] Figure 2 is a block diagram showing an example configuration of a server 10 and a customer terminal 20. The server 10 includes a control unit 11, a storage unit 12, a communication unit 13, an input unit 14, a display unit 15, a reading unit 16, etc., and each of these units is interconnected via a bus. The control unit 11 includes one or more processors such as a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), or a GPU (Graphics Processing Unit). The control unit 11 performs various information processing and control processing that the server 10 should perform by appropriately executing a program 12P stored in the storage unit 12. If the control unit 11 includes multiple processors, the control unit 11 may execute each process using a different processor.

[0014] The storage unit 12 includes a RAM (Random Access Memory), a flash memory, a hard disk, a SSD (Solid State Drive), etc. The storage unit 12 stores in advance a program 12P (program product) executed by the control unit 11 and various data necessary for the execution of the program 12P. Also, the storage unit 12 temporarily stores data and the like generated when the control unit 11 executes the program 12P. Further, the storage unit 12 stores an asset management site 12S for providing an asset management service via the network N. Furthermore, the storage unit 12 stores a customer DB 12a. The storage unit 12 may be composed of a plurality of storage devices, and a part of the storage unit 12 may be another storage device connected to the server 10, or may be another storage device that the server 10 can communicate with.

[0015] The communication unit 13 is a communication module for connecting to the network N by wired communication or wireless communication, and transmits and receives information to and from other devices via the network N. The input unit 14 receives an operation input by the user and sends a control signal corresponding to the operation content to the control unit 11. The display unit 15 is a liquid crystal display, an organic EL display, or the like, and displays various information according to an instruction from the control unit 11. The input unit 14 and the display unit 15 may be a touch panel configured integrally.

[0016] The reading unit 16 reads information stored in a portable storage medium 10a such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a USB (Universal Serial Bus) memory, an SD (Secure Digital) card, a micro SD card, a CompactFlash (registered trademark), etc. The program 12P and various data stored in the storage unit 12 may be read from the portable storage medium 10a by the control unit 11 via the reading unit 16 and stored in the storage unit 12. Also, the program 12P and various data may be written in the storage unit 12 at the manufacturing stage of the server 10, or may be downloaded by the control unit 11 from another device via the communication unit 13 and stored in the storage unit 12.

[0017] In this embodiment, the server 10 may be a multi-computer composed of a plurality of computers, or may be a virtual machine virtually constructed by software within a single device. Further, when the server 10 is composed of server computers, it may be a local server installed within the facility where the server 10 is provided, or may be a cloud server communicatively connected via the network N. Hereinafter, the server 10 will be described as being a single computer. Also, the program 12P may be arranged and executed on a single computer or at a single site, or may be distributed over a plurality of sites and deployed to be executed on a plurality of computers interconnected by the network N. Further, the input unit 14 and the display unit 15 of the server 10 are not essential, and it may be configured to receive operations through a connected computer, or may be configured to output information to be displayed to an external display device.

[0018] The customer terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, a display unit 25, etc., and these units are interconnected via a bus. Since the control unit 21, the storage unit 22, the communication unit 23, the input unit 24, and the display unit 25 of the customer terminal 20 have the same configuration as the control unit 11, the storage unit 12, the communication unit 13, the input unit 14, and the display unit 15 of the server 10, the description thereof will be omitted. The storage unit 22 of the customer terminal 20 stores, in addition to the program 22P (program product) executed by the control unit 21, an application program (hereinafter referred to as the asset management application 22AP) for using the asset management service provided at the asset management site 12S. Also, the storage unit 22 may store a browser for browsing a website (for example, the asset management site 12S) published via the network N instead of the asset management application 22AP.

[0019] Figure 3 is an explanatory diagram showing an example of the record layout of the customer DB 12a. The customer DB 12a is a database that stores information about customers who have registered as users (members) to use the asset management service provided by the server 10. The customer DB 12a shown in Figure 3 includes columns such as customer ID, customer information, account information, and transaction information, and stores various information about the customer in association with the unique identification information (customer ID) assigned to each customer. The customer information column stores information about the customer, such as the customer's name, address or location, contact information, and authentication information used for login processing when using the asset management site 12S. The account information column stores information about the account held by the customer (an account managed by the asset management company), and the account information includes, for example, account type, account number, account holder name, and deposit / withdrawal information. As for the account type, information indicating whether the taxable account is handled as a specified account or whether it is subject to tax exemption (is it a NISA account) is stored. As for the deposit / withdrawal information, the date and amount of deposits made to each account, and the date and amount of withdrawals made from each account are stored. The transaction information column stores information about the transaction status of financial products using funds held by the customer in their account. The transaction information includes, for example, the purchase or sale date of the financial product, and the details of the purchase or sale transaction. The transaction details include the name of the financial product purchased or sold (redeemed), the transaction amount (or transaction unit price and transaction volume), and the reason for the transaction. The reasons for the transaction include, for example, when buying power becomes available in the account (taxable account or non-taxable account) or non-taxable account (installment investment limit or growth investment limit) (buying power available), when the value of the financial product held declines (market value ratio falls below a predetermined value), when it becomes necessary to sell products held in a taxable account to raise funds for a non-taxable account (fundraising), and when there is a change in the financial products held in a taxable account and a non-taxable account (account change). In addition, transaction details for non-taxable accounts include information indicating whether the transaction is under the installment investment limit or the growth investment limit, in addition to the name of the financial product and the transaction amount. The contents of customer DB12a are not limited to the example shown in Figure 3.For example, the remaining amount of the annual investment limit (annual investment amount) in the customer's tax-exempt account, the remaining amount of the tax-exempt holding limit (lifetime available amount), the book value (purchase price), market value, and market value-to-book value ratio (market value / book value) of financial instruments held in the tax-exempt account and taxable account may be stored in the customer DB12a.

[0020] The following describes the processing performed by the server 10 in the information processing system of this embodiment. First, we will describe the processing performed by the server 10 when customer investment funds are deposited into an account managed by an asset management company. Figure 4 is a flowchart showing an example of the deposit processing procedure. The following processing is performed by the control unit 11 of the server 10 according to the program 12P stored in the storage unit 12.

[0021] In this embodiment of the information processing system, a customer accesses the server 10 using a customer terminal 20 and opens their own account in an account managed by the asset management company via the asset management site 12S. The customer also requests, via the asset management site 12S, to execute a deposit process from an account they hold at a financial institution to the newly opened account (the account managed by the asset management company). The server 10 executes the deposit process from the depositing financial institution's account to the receiving account (the account managed by the asset management company) in accordance with the customer's request. In the deposit process, the server 10, for example, sends the customer's account information and authentication information to the server of the depositing financial institution (not shown) to request the execution of a transfer (remittance). If the server of the depositing financial institution can authenticate the customer, it executes a process to deposit the specified amount from the customer's account to the receiving account. As a result, the asset management company receives the customer's investment funds into the customer's account that it manages. Other deposit methods include directly transferring funds from an account held by the customer at a financial institution to a bank account designated by the asset management company for the customer, or setting up automatic withdrawals from the customer's account to deposit funds into an account managed by the asset management company.

[0022] Customers also set their investment schedule for regular investments when opening their account. The regular investment schedule includes the period and amount of investment. For example, a schedule of purchasing 10,000 yen every month can be set. Server 10 retrieves the regular investment schedule set by the user and, based on the set investment schedule, formulates (creates) and stores a purchase plan for financial products within the regular investment limit for the future. Then, when a purchase capacity becomes available within the regular investment limit due to regular deposits, it executes the purchase process for financial products according to the purchase plan. By performing the purchase process according to the purchase plan formulated before the regular deposit is made, regular investments can be made in accordance with the rules of the NISA system. Each customer's purchase plan may be updated at appropriate times, such as when the customer changes their investment policy, when the customer makes deposits or withdrawals, or when financial products are bought or sold, in addition to when the account is opened. Furthermore, the investment schedule may also include the customer's desired industries, categories, etc., in which case Server 10 can formulate a purchase plan targeting products in the industries and categories desired by the customer. The investment schedule for regular contributions may be set separately for the regular contribution allowance in a tax-exempt account and for the regular contributions in a taxable account.

[0023] The control unit 11 of server 10 determines whether or not it has received the customer's funds (S11). If it determines that it has not received the funds (S11: NO), it proceeds to step S16. The control unit 11 performs the deposit processing described above and, if it determines that it has received the customer's funds (S11: YES), it determines whether or not there is space available in the tax-exempt account of the customer who made the deposit (S12). A lifetime available amount (tax-exempt holding limit) is set for the tax-exempt account. In addition, the tax-exempt account has a regular investment limit and a growth investment limit, and an annual investment limit is set for each limit. The control unit 11 calculates the remaining amount at this point relative to the lifetime available amount (remaining amount) and the remaining amount at this point relative to the annual investment limit for each of the regular investment limit and growth investment limit. If the remaining amount of the lifetime available amount is not 0, and the remaining amount of the annual investment limit for either the regular investment limit or the growth investment limit is not 0, it determines that there is space available in the tax-exempt account. On the other hand, the control unit 11 determines that there is no available space in the tax-exempt account if the remaining amount of the lifetime available funds is 0, or if the remaining amount of the annual investment available funds for both the regular investment limit and the growth investment limit is 0. The remaining amount of the lifetime available funds, and the remaining amount of the annual investment available funds for both the regular investment limit and the growth investment limit may be stored in the customer DB 12a, or the control unit 11 may calculate them based on the transaction information stored in the customer DB 12a. If the control unit 11 determines that there is no available space in the tax-exempt account (S12: NO), it proceeds to step S15.

[0024] If the control unit 11 determines that there is available space in the tax-exempt account (S12: YES), it allocates the deposited funds to the customer's tax-exempt account, up to the amount not exceeding the annual investment limit of the tax-exempt account (S13). For example, the control unit 11 allocates the remaining amount of the annual investment limit of the tax-exempt account from the deposited funds to the tax-exempt account. When funds are allocated to the tax-exempt account, buying power is generated in the tax-exempt account, and investment using the funds in the tax-exempt account begins. Once the allocation process to the tax-exempt account is complete, the control unit 11 stores the deposit date and amount, etc., as deposit information for the customer's tax-exempt account in the customer DB 12a. After the allocation process to the tax-exempt account, the control unit 11 determines whether there is a remaining balance in the funds received in step S11 (S14). If the control unit 11 determines that there is no balance (S14: NO), that is, if all funds are allocated to the tax-exempt account, it proceeds to step S16. If it determines that there is a balance (S14: YES), it allocates the remaining balance to the customer's taxable account (S15). When funds are allocated to the taxable account, buying power is generated in the taxable account, and investment using the funds in the taxable account begins. Here again, once the allocation of funds to the taxable account is completed, the control unit 11 stores the deposit information to the customer's taxable account in the customer DB 12a.

[0025] As a result of the above process, when customer funds are deposited, the funds are preferentially allocated to the tax-exempt account, so investments using the funds in the tax-exempt account are executed preferentially. Also, if funds exceeding the annual investment limit of the tax-exempt account are deposited, the excess funds are allocated to the taxable account, so investments using the funds in the taxable account are executed. The annual investment limit of the tax-exempt account is the investment limit for one year from January to December, and in January the annual investment limit (annual investment limit) is reset, and if there was a sale or redemption of securities in the tax-exempt account in the previous year, the lifetime investment limit is restored. Therefore, in January, there is a possibility that new vacancies will become available in the tax-exempt account. So, while performing the above process, the control unit 11 determines whether or not there are vacancies in the tax-exempt account (whether or not vacancies have occurred) (S16). Here, the control unit 11 determines that there is space available in the tax-exempt account if, after deducting the planned consumption amount of the tax-exempt account through the set installment deposits, the remaining amount of the lifetime available funds is not zero, and the remaining amount of the annual investable funds for either the installment investment limit or the growth investment limit is not zero. On the other hand, the control unit 11 determines that there is no space available in the tax-exempt account if the remaining amount of the lifetime available funds is zero, or if the remaining amount of the annual investable funds for both the installment investment limit and the growth investment limit is zero. If it determines that there is no space available (S16: NO), the control unit 11 returns to step S11 and either accepts the deposit of funds or repeats the process from steps S11 to S16 until space becomes available in the tax-exempt account.

[0026] If the control unit 11 determines that there is (or has become) free space in the tax-exempt account (S16: YES), it executes a process to sell or redeem financial products held in the taxable account (referred to as a sale process in Figure 4, and collectively as a sale below) in order to raise funds equivalent to the free space in the tax-exempt account (S17). For example, the control unit 11 sells financial products equivalent to the remaining amount of the annual investable limit in the tax-exempt account. If the customer does not hold financial products equivalent to the remaining amount of the annual investable limit in the tax-exempt account in the taxable account, the control unit 11 may sell all financial products held in the taxable account. If a trading server (not shown) is provided to perform the sale and purchase of financial products, the control unit 11 sends a request to the trading server to execute the sale process for the financial products held by the customer in the taxable account, and the sale process is performed by the trading server. Alternatively, the server 10 may have the functionality of a trading server, in which case the control unit 11 of the server 10 executes the process related to the sale of financial products. When the sale process is completed, the control unit 11 stores the sale date and transaction details in the customer DB 12a as transaction information for the customer's taxable account. The transaction details include the name of the financial product sold (canceled), the transaction amount (or transaction unit price and transaction volume), the reason for the transaction (reason for the transaction occurring), etc., where the reason for the transaction is, for example, to raise funds for a tax-exempt account. The control unit 11 then allocates (moves) the funds obtained from the sale process from the taxable account to the tax-exempt account (S18). When funds are moved to the tax-exempt account in this way, buying power is generated in the tax-exempt account, and investment using the funds in the tax-exempt account becomes possible. Here, the control unit 11 stores the withdrawal information to the customer's taxable account and the deposit information to the tax-exempt account in the customer DB 12a.

[0027] Subsequently, the control unit 11 returns to step S11 and executes the above-described process each time a new deposit of funds is received or each time a vacancy arises in the tax-exempt account. This allows for investment that effectively utilizes the annual investment limit of the tax-exempt account by selling financial products held in the taxable account to raise funds and transferring them to the tax-exempt account when a vacancy arises in the tax-exempt account. In the above-described process, instead of determining whether there is a vacancy in the tax-exempt account in step S16, the control unit 11 may determine whether it is January 1st, and if it determines that it is January 1st, it may determine whether the remaining amount of the lifetime available funds is 0. In this case, the control unit 11 may be configured to sell financial products held in the taxable account and transfer the funds obtained from the sale to the tax-exempt account if it determines that it is January 1st and that the remaining amount of the lifetime available funds at this point is not 0.

[0028] Through the process described above, if an amount exceeding the annual investment limit of the tax-exempt account is deposited, the excess amount is temporarily allocated to the taxable account and used for investment. When a vacancy arises in the tax-exempt account, the funds are automatically transferred from the taxable account to the tax-exempt account. Therefore, customers only need to deposit funds when opening an account or when they have secured a lump sum of money, and thereafter, investments utilizing the tax-exempt limit will be made without any further action from the customer.

[0029] Next, we will explain the process by which server 10 reduces the principal of financial instruments by selling the financial instruments held in the tax-exempt account according to their market value, and then purchasing the same financial instruments that were sold. The financial instruments to be purchased may be the same as the financial instruments sold, or other securities of the same type as the financial instruments sold, or instruments that are similar to the financial instruments sold in terms of industry, category, and expected return. Figure 5 is a flowchart showing an example of the principal reduction process. The control unit 11 of server 10 performs the following process for each customer periodically, for example, once every 12 hours, once a day, once a week, etc.

[0030] The control unit 11 of server 10 retrieves information on the growth investment limit of a tax-exempt account held by a customer from customer DB 12a (S21). For example, the control unit 11 reads from customer DB 12a the remaining amount of the lifetime available amount for the tax-exempt account, the remaining amount of the lifetime available amount for the growth investment limit of the tax-exempt account, the remaining amount of the annual investment limit for the growth investment limit, the book value and market value of the financial instruments held in the growth investment limit, and the planned amount of consumption of the tax-exempt account through set-up deposits. Based on the retrieved information, the control unit 11 determines whether there are any financial instruments held in the growth investment limit that meet the sale conditions (S22). The sale conditions are, for example, when the market value-to-book value ratio (market value-to-book value ratio = market value / book value), which shows the ratio of the market value to the book value of the financial instrument, is less than or equal to a predetermined value. The predetermined value for determining whether the sale conditions are met may be any number such as 0.9 or 0.8, or it may be arbitrarily changed according to instructions from the asset management company's representative or the customer. Therefore, based on the acquired information, the control unit 11 calculates the market-to-book value ratio for each financial product held in the growth investment framework and determines whether there are any financial products whose market-to-book value ratio is below the predetermined value. The control unit 11 may also determine that the sale conditions are met if the difference (decrease) between the book value and market value of a financial product exceeds a predetermined value, and this predetermined value may also be predetermined or arbitrarily changed.

[0031] If the control unit determines that there are financial instruments that meet the sale conditions (S22: YES), it determines whether or not to immediately sell the financial instruments that meet the sale conditions (S23). The determination of whether or not to immediately sell can be made using, for example, the remaining amount of the lifetime available amount of the growth investment limit, the remaining amount of the annual available investment amount of the growth investment limit, or the buying power of the growth investment limit. For the remaining amount of the lifetime available amount and the remaining amount of the annual available investment amount of the growth investment limit, the criterion for determining whether each remaining amount is equal to or greater than the amount required to purchase the financial instruments that meet the sale conditions. In addition, for the buying power of the growth investment limit, the criterion for determining whether or not there is buying power of a predetermined amount or more in the growth investment limit, and if there is buying power, it is determined that the instruments should be immediately sold. The predetermined amount here is the amount of money that can be used to purchase after selling the financial instruments that meet the sale conditions, and can be the difference between the amount obtained by selling the financial instruments and the amount required to purchase them (amount required to purchase - amount obtained by selling). Furthermore, since the timing of selling a financial product and the timing of purchasing that financial product are not the same, the amount obtained from selling and the amount required to purchase are not the same. If there is sufficient purchasing power in the growth investment framework to cover this difference, it can be determined that the product should be sold immediately. Therefore, based on the acquired information, the control unit 11 determines whether the remaining annual investment amount in the growth investment framework is less than or equal to the remaining lifetime investment amount in the growth investment framework, and whether it is equal to or greater than the amount required to purchase a financial product that meets the selling conditions. If these conditions are met, the control unit 11 determines that the product should be sold immediately. Alternatively, the control unit 11 may determine whether the financial product should be sold immediately based on whether there is sufficient purchasing power in the growth investment framework to cover a predetermined percentage (e.g., 5%, 10%, etc.) of the amount obtained from selling the financial product that meets the selling conditions.

[0032] If the control unit 11 determines that the financial instrument should be sold immediately (S23:YES), that is, if the remaining annual investment amount of the growth investment limit after deducting the planned consumption amount of the tax-exempt account through the set installment deposits is less than or equal to the remaining lifetime investment amount of the growth investment limit, and is greater than or equal to the amount required to purchase a financial instrument that meets the sale conditions, the control unit 11 executes the sale process for the financial instrument (S24). Here, the control unit 11 sends a request to the trading server to execute the sale process for the financial instrument held by the customer in the growth investment limit. As a result, the trading server executes the sale process, and when the sale process is completed, the control unit 11 stores the sale date and transaction details in the customer DB 12a as transaction information for the customer's tax-exempt account (growth investment limit). The reason for the transaction here is, for example, a decline (the market value book value ratio falls below a predetermined value). Then, the control unit 11 executes a purchase process to purchase a financial instrument of the same security as the financial instrument that was sold in the growth investment limit (S25). In the purchase process, the control unit 11 sends a request to the trading server to execute the purchase process of financial products using the customer's growth investment funds, which is then carried out by the trading server. When the purchase process is completed, the control unit 11 stores the purchase date and transaction details in the customer DB 12a as transaction information for the customer's tax-exempt account (growth investment fund). The reason for the transaction here may be a decline, similar to the sale process in step S24.

[0033] Through the process described above, if the criteria for deciding to sell immediately are met, the financial instrument held in the growth investment framework will be sold and a financial instrument of the same security will be purchased when the sale conditions are met. By performing the above process when the market value of a financial instrument falls below its book value, the book value of the financial instrument can be reduced, and as a result, the principal of the financial instrument can be reduced. In the NISA system, when securities etc. held in a tax-free account are sold, an amount equivalent to the book value is restored as lifetime available funds the following year, so the lifetime available funds of the tax-free account can be increased by the amount of the portion that was effectively reduced. For example, if a financial instrument purchased for 1 million yen is sold and repurchased when its market value falls to 700,000 yen, the principal (book value) of the financial instrument can be reduced from 1 million yen to 700,000 yen. This transaction temporarily increases the lifetime usage limit of the tax-exempt account to 1.7 million yen, but the lifetime usage limit is restored to its original book value of 1 million yen the following year, effectively increasing the lifetime usage limit of the tax-exempt account by 300,000 yen. In this way, by reducing the principal of the financial products held, it is possible to effectively increase the lifetime usage limit of the tax-exempt account, and such transactions will be referred to as limit-saving transactions below.

[0034] If the control unit 11 determines that the investment should not be sold immediately (S23: NO), that is, if the remaining amount of the annual investment limit in the growth investment framework after deducting the planned consumption amount of the tax-exempt account through the set installment deposits is less than or equal to the remaining amount of the lifetime investment limit, but less than the amount required to purchase a financial product that meets the sale conditions, the control unit 11 executes a sale reservation process and a purchase reservation process for the financial product (S26). The sale reservation process is a process in which the control unit 11 stores in the storage unit 12 a reservation for the execution of a process to send a request to the trading server to execute the sale process for the financial product on the scheduled sale date, for example, on a predetermined date (e.g., the first day, an intermediate day, or the last day) within the period (predetermined period) during which the sale and settlement can be made from mid-December onwards (within December). As a result, the execution of the sale process is reserved, and when the scheduled sale date arrives, the control unit 11 sends the request to the trading server to execute the sale process, thereby executing the sale process. Furthermore, the purchase reservation process sets a predetermined date in January of the following year (for example, the first day on which the financial product can be purchased) as the scheduled purchase date, and stores in the storage unit 12 a reservation for the control unit 11 to send a request to the trading server to execute the purchase process for the financial product on the scheduled purchase date if the sale process for the financial product has been executed. As a result, the execution of the purchase process is reserved, and when the scheduled purchase date arrives after the sale process for the financial product has been executed, the control unit 11 sends the request to the trading server to execute the purchase process, thereby executing the purchase process. The control unit 11 may also re-determine whether the financial product to be sold meets the sale conditions when the scheduled sale date arrives, and may perform the sale process if it determines that the sale conditions are met. The control unit 11 may also send a request to the trading server to execute the sale process for the financial product on the scheduled sale date without waiting for the scheduled sale date to arrive, or send a request to the trading server to execute the purchase process for the financial product on the scheduled purchase date after the sale of the financial product without waiting for the scheduled purchase date to arrive.

[0035] If the control unit 11 determines in step S22 that there are no financial products that meet the selling conditions (S22: NO), the control unit 11 proceeds to step S27. After processing in step S25 or step S26, the control unit 11 performs the same processing for the regular investment limit. Specifically, the control unit 11 obtains information on a customer's regular investment limit from the customer DB 12a (S27) and determines whether there are any financial products among the financial products held in the regular investment limit that meet the selling conditions (S28). If the control unit 11 determines that there are financial products that meet the selling conditions (S28: YES), it determines whether the financial product should be sold immediately (S29). If the control unit 11 determines that it should be sold immediately (S29: YES), it executes the sale process for the financial product (S30), and then executes a purchase process to purchase a financial product of the same security as the sold financial product using the growth investment limit (S31). Here, the control unit 11 sends a request to execute a sell process and a request to execute a buy process to the trading server, and the trading server executes the sell process and the buy process. The control unit 11 then stores the transaction information for the completed sell process and the buy process in the customer DB 12a for the customer's tax-exempt account. Here, the control unit 11 stores the information for the sell process as transaction information for the regular investment limit and the information for the buy process as transaction information for the growth investment limit. The reason for the transaction here can also be, for example, a decline (the market value to book value ratio falls below a predetermined value). Therefore, even with the regular investment limit, if there is buying power when the market value of a financial product falls below its book value, the principal of the financial product can be reduced by selling the financial product and purchasing the same financial product, thereby effectively expanding the lifetime available amount of the tax-exempt account.

[0036] On the other hand, if the control unit 11 determines that the financial instrument should not be sold immediately (S29: NO), it executes a sale reservation process and a purchase reservation process for the financial instrument (S32). Therefore, even with the investment limit, if the market value of the financial instrument falls below the book value and there is no available funds to buy, the control unit 11 executes a sale reservation for the financial instrument and a purchase reservation for the same instrument. As a result, when the scheduled sale date arrives, the sale process is executed, and if the scheduled purchase date arrives after the sale process has been executed, the purchase process is executed. If the control unit 11 determines in step S28 that there are no financial instruments that meet the sale conditions (S28: NO), it terminates the process. The control unit 11 executes the above process for each customer registered in the customer DB 12a, and if there are financial instruments that meet the sale conditions, it executes the sale process and purchase process, or the sale reservation process and purchase reservation process, for the financial instruments.

[0037] Through the process described above, if the market value of financial instruments held in a tax-exempt account falls below its book value, the principal of those financial instruments can be reduced through limit-of-charge transactions, effectively expanding the lifetime available amount in the tax-exempt account. In the process described above, steps S25 and S31 describe a configuration in which financial instruments of the same type as those sold in steps S24 and S30 are purchased, but the configuration is not limited to this. For example, a configuration in which financial instruments of the same type as those sold are purchased, but of a different type, is also acceptable. Alternatively, a configuration in which financial instruments similar to those sold are purchased, such as those in the same industry, category, and with similar (or similar) expected returns. In this case, the configuration should be such that financial instruments of an amount roughly equivalent to the amount obtained by selling the financial instruments in steps S24 and S30 are purchased. The expected return is the rate of return that can be expected to be obtained in the future if an investment is made, and is calculated by an asset management company, etc., based on various information about the financial instruments and the economic growth rate. The expected return may be stored in the memory unit 12, or it may be obtained from another server via the network N. As mentioned above, purchasing the same, the same type of, or similar product as the one sold can reduce the principal of the product whose market value has declined. However, it is also acceptable to purchase other products that are in a different industry, category, etc., than the financial product sold. In this case as well, since the unrealized losses due to the decline in the market value of the financial products held in the tax-exempt account are eliminated (the unrealized losses are realized), it effectively leads to an increase in the lifetime available balance of the tax-exempt account, similar to limit-saving transactions.

[0038] The control unit 11 of the server 10 periodically performs the above-described process for each customer and automatically executes a limit-of-sale transaction when a financial product that meets the sales conditions becomes available. Customers can access the server 10 using the customer terminal 20 and check the transaction history of financial products held in their accounts via the asset management site 12S. Figure 6 is an explanatory diagram showing an example of the limit-of-sale transaction history screen, where Figure 6A shows an example of displaying history information for a limit-of-sale transaction executed immediately, and Figure 6B shows an example of displaying reservation history information for a limit-of-sale transaction. In the example of Figure 6A, the execution date of the limit-of-sale transaction, the name of the financial product sold by the limit-of-sale transaction, the sale date, the book value and market value at the time of sale of the financial product sold, the name of the financial product purchased by the limit-of-sale transaction, the purchase date, the book value of the financial product purchased, etc. are displayed. In the example in Figure 6B, the reservation date for the limit-of-payment transaction, the name of the financial product to be sold through the limit-of-payment transaction, the planned sale date, the book value of the financial product to be sold, the name of the financial product to be purchased through the limit-of-payment transaction, the planned purchase date, and the market value of the financial product to be purchased at the time of the limit-of-payment transaction reservation are displayed. In addition, the screens in Figures 6A and 6B display the amount of increase in the lifetime available balance (limit-of-payment effect) that will be effectively increased by the reduction of principal through the limit-of-payment transaction. Through such screens, customers can understand the execution history and planned execution status of limit-of-payment transactions for the financial products they hold. The control unit 11 may also display the reason why the limit-of-payment transaction occurred on the screens in Figures 6A and 6B. For example, the reason for the limit-of-payment transaction may be that the conditions for sale are met, specifically that the market value-to-book value ratio has fallen below a predetermined value.

[0039] Next, we will describe the process by which server 10 purchases financial products when there is (if) sufficient buying power in at least one of the customer's taxable and non-taxable accounts. Figure 7 is a flowchart showing an example of the purchase process.

[0040] The control unit 11 of the server 10 determines whether a customer has buying power in their account (taxable account and / or non-taxable account) (S41). The determination of whether there is buying power is performed periodically, for example, once every few hours or once a day. For example, after funds are deposited into the non-taxable account in steps S13 and S18 in Figure 4, and after funds are deposited into the taxable account in step S15, the control unit 11 determines that there is buying power.

[0041] If it is determined that there is sufficient purchasing power (S41: YES), the control unit 11 determines whether the requirements for purchasing financial products within the tax-exempt account's installment investment limit are met (S42). Here, the control unit 11 determines whether it corresponds to a predetermined periodic purchase within the annual investment limit and the lifetime available limit of the installment investment limit, and if it determines that it corresponds to a periodic purchase, it determines that the purchase requirements for the installment investment limit are met. If it is determined that the purchase requirements for the installment investment limit are met (S42: YES), the control unit 11 allocates the amount of the purchasing power to the installment investment limit and executes a purchase process to purchase financial products within the installment investment limit (S43). Here, the control unit 11 identifies the financial products to be purchased and the purchase quantity (transaction volume) within the scope of the purchasing power, based on the purchasing power (amount of products that can be purchased) of the installment investment limit, the portfolio of candidate financial products set for the customer, etc., and executes a process to purchase the identified financial products. When the purchase process is completed, the control unit 11 stores the purchase date and transaction details in the customer DB 12a as transaction information for the customer's investment plan. The reason for the transaction here could be, for example, that there is sufficient buying power.

[0042] If it is determined that the purchase requirements for the regular investment limit are not met (S42: NO), the control unit 11 determines whether the purchase requirements for financial products in the tax-exempt account's growth investment limit are met (S44). Here, the control unit 11 determines whether there is sufficient purchasing power within the annual investment limit and lifetime available limit of the growth investment limit, and if it determines that there is sufficient purchasing power within that range, it determines that the purchase requirements for the growth investment limit are met. If it is determined that the purchase requirements for the growth investment limit are met (S44: YES), the control unit 11 executes a purchase process to purchase financial products in the growth investment limit (S45). Step S45 is the same process as step S43, although the purchase limit for financial products is different, and executes a process to purchase financial products within the purchasing power of the growth investment limit. In addition, in the purchase process for the growth investment limit, the control unit 11 may obtain the expected return for each candidate financial product and execute the purchase process for products with the highest expected returns first. When the purchase process is completed, the control unit 11 stores the purchase date and transaction details in the customer DB 12a as transaction information within the customer's growth investment framework, and the reason for the transaction is also set to "buying power available".

[0043] If it is determined that the purchase requirements for the growth investment framework are not met (S44: NO), the control unit 11 executes a purchase process to purchase financial products in the taxable account (S46). Step S46 is the same process as step S43, although the purchase account for the financial products is different, and executes a process to purchase financial products within the limits of the buying power of the taxable account. When the purchase process is completed, the control unit 11 stores the purchase date and transaction details in the customer DB 12a as transaction information for the customer's taxable account. After the processing in step S43 or step S45, the control unit 11 returns to step S41 and, if there is buying power in the customer's account, repeats the process described above.

[0044] The control unit 11 terminates the above process if it determines that there is no available funds to purchase (S41: NO), or after processing in step S46. As a result of the above process, if funds become available in the customer's account, purchases are prioritized for the regular investment limit, then for the growth investment limit, and only if purchases in the tax-exempt account are possible are purchases in the taxable account. By prioritizing purchases in the tax-exempt account whenever possible, the system enables investment that effectively utilizes the tax-exempt account limit. Furthermore, by prioritizing the regular investment limit, which has stricter usage conditions than the growth investment limit, the growth investment limit, which has looser usage conditions, can be kept open, ensuring greater flexibility for future transactions. Additionally, in the above process, when purchasing financial products within the growth investment limit, the system prioritizes the purchase of products with high expected returns, thereby minimizing the expected tax costs on taxable financial products.

[0045] Next, we will explain the process by which server 10 withdraws funds from a customer's account (taxable account and / or non-taxable account). Figure 8 is a flowchart showing an example of the withdrawal process. The control unit 11 of server 10 identifies financial instruments that are candidates for sale from among the financial instruments held in a customer's account (taxable account and / or non-taxable account) (S61). For example, the control unit 11 identifies the financial instrument held by the customer that most exceeds the target holding ratio as a candidate for sale. Alternatively, it may identify financial instruments whose market value book value ratio is below a predetermined value as candidates for sale. The control unit 11 also identifies the planned sale quantity (transaction volume) for the financial instruments identified as candidates for sale.

[0046] The control unit 11 determines whether the financial instrument identified as a candidate for sale (the item to be sold) is held in a taxable account (S62). If it determines that it is held in a taxable account (S62:YES), it executes the sale process for the financial instrument held in the taxable account (S63). The control unit 11 sells the financial instrument held in the taxable account within the range of the planned sale volume identified for the financial instrument. Once the sale process is complete, the control unit 11 stores the sale date and transaction details (the reason for the transaction is, for example, a decline) in the customer DB 12a as transaction information for the customer's taxable account. If it determines that it is not held in a taxable account (S62:NO), the control unit 11 determines whether the financial instrument identified as a candidate for sale is held in the growth investment framework of a tax-exempt account (S64). If it determines that it is held in the growth investment framework (S64:YES), the control unit 11 executes the sale process for the financial instrument held in the growth investment framework (S65). Here too, the control unit 11 sells the financial instruments that are candidates for sale, which are held in the growth investment framework, within the range of the specified planned sale volume. When the sale process is completed, the control unit 11 stores the sale date and transaction details (the reason for the transaction being, for example, a decline) in the customer DB 12a as transaction information for the customer's growth investment framework.

[0047] If the control unit 11 determines that the financial product identified as a candidate for sale is not held in the growth investment framework (S64: NO), it executes the sale process for the financial product held in the regular investment framework (S66). Here again, the control unit 11 sells the financial product held in the regular investment framework within the range of the identified planned sale quantity. Once the sale process is complete, the control unit 11 stores the sale date and transaction details (transaction reason being, for example, a decline) in the customer DB 12a as transaction information for the customer's regular investment framework.

[0048] After processing in step S63 or step S65, the control unit 11 returns to step S61 and repeats the above-described process each time it identifies a potential product for sale among the financial instruments held in the customer's account. When the above-described process results in a potential product for sale being found in the customer's account, the sale of the potential product for sale held in the taxable account is given top priority, followed by the sale of the potential product for sale held in the growth investment framework, and finally the sale of the potential product for sale held in the regular investment framework. In this way, if there is a potential product for sale in the taxable account, the sale of the taxable account is given priority, thereby making effective use of the tax-exempt account framework. Furthermore, by prioritizing the sale of financial instruments held in the growth investment framework over the regular investment framework, it is possible to preferentially free up space in the growth investment framework, which has fewer restrictions on usage conditions, thereby ensuring greater flexibility for future transactions.

[0049] Next, we will describe the process by which the server 10 replaces the financial products held in each account based on the expected returns of the financial products held by the customer in both taxable and tax-exempt accounts. Figure 9 is a flowchart showing an example of the replacement process. The control unit 11 of the server 10 obtains the expected returns of each financial product held in a customer's account (taxable account and / or tax-exempt account) (S81). The control unit 11 determines whether there are any financial products held in the taxable account whose expected return is greater than the expected return of the financial products held in the tax-exempt account (S82). If it is determined that there are no financial products in the taxable account whose expected return is greater than the expected return of the financial products held in the tax-exempt account (S82: NO), the control unit 11 terminates the process. Note that, for example, before step S81, the control unit 11 may determine whether there is available space in the customer's tax-exempt account (there is remaining funds in the lifetime available balance), and if it is determined that there is no space, it may execute the process from step S81 onwards. In this case, if there is available space in the tax-exempt account, the purchase process in the tax-exempt account is performed according to the process in Figure 7.

[0050] Therefore, if there is no remaining balance in the lifetime available amount of the tax-exempt account, and the control unit 11 determines that there are financial products in the taxable account whose expected return is greater than the expected return of the financial products held in the tax-exempt account (S82: YES), the control unit 11 identifies the financial products to be replaced (products to be replaced) between the financial products held in the taxable account and the financial products held in the tax-exempt account (S83). For example, the control unit 11 identifies the financial product with the highest expected return among the financial products held in the taxable account and the financial product with the lowest expected return among the financial products held in the tax-exempt account as the products to be replaced.

[0051] The control unit 11 then executes a sale process for financial instruments held in the tax-exempt account that have been identified as targets for replacement (S84), and executes a sale process for financial instruments held in the taxable account that have been identified as targets for replacement (S85). The control unit 11 also executes a purchase process to buy the same financial instruments that were sold in step S85 and held in the taxable account using funds from the tax-exempt account (S86), and executes a purchase process to buy the same financial instruments that were sold in step S84 and held in the tax-exempt account using funds from the taxable account (S87). Here again, the control unit 11 may purchase not only the same financial instruments that were held in the taxable account or the tax-exempt account, but also financial instruments similar to the sold financial instruments or other financial instruments. Furthermore, in steps S84 and S85, the control unit 11 may, for example, execute the sale process for the financial product to be replaced after mid-December, and in steps S86 and S87, execute the purchase process for the financial product to be replaced in the tax-exempt account after the lifetime available amount of the tax-exempt account has recovered in the following year. Also, when the purchase process is performed using funds from the tax-exempt account in step S86, the control unit 11 executes the purchase process after determining whether there is sufficient purchasing power (purchase amount) in the tax-exempt account (accumulation investment limit or growth investment limit). Here again, when the sale process is completed, the control unit 11 stores the sale date and transaction details (transaction reason is, for example, account replacement) in the customer DB 12a as transaction information for each account or each section of the tax-exempt account of the customer, and when the purchase process is completed, the control unit 11 stores the purchase date and transaction details (transaction reason is, for example, account replacement) in the customer DB 12a as transaction information for each account or each section of the tax-exempt account of the customer.

[0052] Through the process described above, if the expected return of financial instruments held in a taxable account is greater than the expected return of financial instruments held in a tax-exempt account, the expected tax cost on taxable financial instruments can be minimized by swapping the financial instruments held in the taxable and tax-exempt accounts, respectively.

[0053] In the information processing system of this embodiment, the server 10 executes the processes shown in Figures 4-5 and 7-9 in parallel or sequentially, and automatically performs the buying and selling of financial products by performing a sell process if it is necessary to sell the financial products held by each customer, and performing a purchase process if it is necessary to purchase new financial products. Therefore, customers can make investments that effectively utilize the tax-free account limit without having to understand the complicated NISA system, simply by making a deposit. Note that by setting different conditions for selling in steps S22 and S28 in Figure 5 and for the conditions for sale candidates in step S61 in Figure 8, the processes in Figure 5 and Figure 8 can be executed separately. In addition, in the information processing system of this embodiment, if the server 10 determines that it should execute a sell process or a purchase process, it may notify the customer via the customer terminal 20 of the scheduled execution of the sell process or purchase process, and execute the sell process or purchase process after obtaining permission from the customer.

[0054] Figure 10 is an explanatory diagram showing an example screen. Customers can access the server 10 using the customer terminal 20 and check the buying and selling history (transaction history) of financial products held in their account via the asset management site 12S. In the example shown in Figure 10, the purchase or sale date of the financial products held by the customer, the name of the financial product purchased or sold, the transaction details, and the reason why the transaction occurred are displayed. The reason for the transaction includes, for example, the creation of buying power in a taxable or non-taxable account (buying power available), or the decline in value of the financial product held (market value ratio falling below a predetermined value). Through such a screen, customers can understand the financial products they hold and also understand their past buying and selling history, along with the reason why each buying and selling transaction occurred.
