Description

METHOOD, SYSTEM AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM FOR SUPPORTING SECURITIES SHORT SALE USING DISTRIBUTED LEDGER}

The present invention relates to a method, system and non-transitory computer readable recording medium for supporting securities short selling using distributed ledgers.

Securities lending and borrowing transaction means that the lender commits the transfer of ownership of the securities to the borrower and the borrower agrees to return the securities of the same item and quantity as the securities. Securities consumption loan transaction agreement. Once a loan is established, the securities' disposal rights and revenue streams are transferred to the borrower, who in turn pays back the borrower's rights (e.g. cash or stock dividends, free shares, etc.) , Paid shares, etc.).

Lending has been used to achieve a variety of purposes. Specifically, short selling transactions, arbitrage transactions through short selling, and collateral are used as collateral. transaction, a fail coverage transaction, a recall coverage transaction if a request for recovery of an existing loan transaction is received (recall coverage transaction), a lower fee It is used for the purpose of replacing a balance with a balance (refinancing transaction), and replacing the balance of the existing balance with a more stable balance.

In most countries, in order for a borrower to short sell securities, the borrower must own the securities borrowed prior to the short selling order, at which point it is recognized that he or she owns the borrowed securities. This is when the borrowing of the securities is completed or the loan contract for the securities is finalized. Most short traders place short quotes for short selling as soon as the contract is finalized. When proceeding with a loan agreement, you will go through the steps of searching, negotiating, and confirming the balance of the security of the securities. You will receive a confirmation. Some countries, such as the United States and Hong Kong, allow short selling transactions after receiving a hold confirmation from the lender, without a loan agreement being finalized. This is a method of completing a loan transaction after a short selling transaction, and there is no need to prepay, so the procedure is simple and the cost of collateral and securities borrowing can be significantly reduced.

Lending necessary for short selling is often a process by which borrowers apply for borrowing to borrowing entities and approve it to the lender, which is an intermediary for stock borrowing. and lending). The intermediary is responsible for managing the entire process of lending and repaying securities. For example, in the event of a repayment or recall of a loan, the borrower will reimburse the lender by the due date for the borrower, and will also be subject to loan fees, rights obligations (e.g., dividends, rights increase, free increase). ) By the due date. In some cases, the collateral provided by the borrower is managed instead. If the borrower fails to return the borrowed securities due to bankruptcy or other reasons, the collateral is sold to the market to minimize the loss of the lender.

On the other hand, every short market participant must prove that he or she owned the stock at each short sale (that is, it was already borrowed or a borrowing contract was established (or, in some cases, held for the securities to be borrowed). A representative means of doing so is a unique identifier that identifies the borrowing agreement. In English, reference ID / number for approved borrow request (s); securities lending confirmation number; settlement number for borrowed securities; indication of interest; It can mean a hold confirmation number, etc. It can also be used interchangeably with a locate number or locate ID. Typically, such loan confirmation evidentiary identifiers (hereafter referred to as locate IDs) are included in a borrow confirmation generated at the time of each short sale order and sent to the borrower. Although a loan confirmation alone may prove that the loan agreement has been completed, if information about the issue time, issue date, and quantity available for rental can be stored when generating a locate ID, the locate can be later added. ID) At the time of creation, the lender had a sufficient amount of loan, and it was created before the short sale, and it is possible to prove that the borrower received it from the lender before the short selling, so that the loan transaction can be replaced. In practice, high frequency trading trading techniques require the use of computer-readable locate IDs rather than unstructured loan confirmations or loan confirmations. do. If a short sale is made through a loan and no securities are borrowed (i.e. without a loan confirmation letter (or balance check, balance check statement, etc.) or a proof of borrowing confirmation that proves it), It is called naked short selling and is strictly prohibited in most countries that allow short selling.

However, according to the prior art as described above, including the prior art, there are the following problems.

First, based on the above-mentioned lending transactions, in the short selling transactions, not only the trading parties, but also other relevant institutions (financial regulators, stock exchanges, brokers, lending brokers), in effect, are not subject to any loan confirmation. Or there's no way to know for sure that it's based on a locate ID. Therefore, in most countries, if the stock exchange or broker receives that the trading party has sufficient quantity to make a short selling, it allows the short selling without further verification. After the loan is passed from the lender to the borrower, the amount is combined with other quantities to be used for a short sale transaction, and some of the amount is repaid, and it is impossible to match the borrowed quantity with the short selling and locate ID. Become.

Second, to buy back, short cover, or borrow return on borrowed, short or short sale positions outstanding. The lack of a link between the various stages of the transaction process makes it impossible to identify a series of loan and short selling life cycles, namely the securities lending and short selling lifecycle. The existing method of generating a location ID is mainly made by a prime broker, which provides a loan amount to a hedge fund, to secure a short selling amount from the outside or the inside, and then generate it by itself. Has been granted. Even if the prime broker makes a short sale on its own for the purpose of stock swap, it will generate and assign a locate ID to itself after securing the quantity from the outside or the inside. The generated locate ID is a serial number that is not recognized except by the trading party or the prime broker supporting the transaction and is not directly related to the transaction, such as a lender, broker, exchange, or financial oversight body. From the standpoint, the short selling entity is merely an institutional serial number claiming to have completed a borrowing or borrowing contract prior to the short selling. Therefore, rather than locate ID, which can be used to unify a series of balances and short selling by using the market as a whole, it is necessary to identify all processes related to balance and short selling using the existing locate ID generation method. Is practically impossible.

Third, market participants, especially short sellers, should be able to prove that a transaction is a borrow short selling at a later request from a financial regulator. There may be problems such as additional costs, cumbersome procedures, and transaction delays in order to prove this, and it is difficult to solve such problems with existing technologies that cannot unify and unbundle transactions related to short selling with irreversible information.

Financial supervisors in some countries consider increases or decreases in net position by referring to the day of purchase, long sale, and short sale of the institution that made the short sale at the time of the transaction or on that day. By doing so, efforts have been made to identify violations of short selling. In this case, the term net assets is generally the amount sold by the institution minus the total selling volume.In the case where the initial purchase quantity for a security is 100 weeks, the general selling quantity after buying is 50 weeks, and after the buying quantity is 100 shares. For example, the net asset is -50 shares (ie 100-50-100 = -50 shares), where the borrower must be able to prove to the financial regulator that internal or external borrowing of 100 short selling units has been preceded. Accordingly, the supervisory authority will check whether or not sufficient short selling volume has been secured at the time of short selling based on this net asset method.

The fundamental problem with this type of surveillance is that it is difficult to detect when a short selling transaction occurs. The market watcher compares the time stamp, date and quantity and the short selling quantity and timing of the borrowing included in the balance sheet, which are almost impossible to check and compare. In addition, if the net asset method mentioned above is considered, the net asset is only negative. Therefore, if the net asset is positive, it may not be easily found (flagging) even when the borrowing is short.

Fourth, modification of the loan confirmation and locate ID is possible. In particular, if the subject of the short selling is an agency located overseas, the audit is conducted through a domestic corporation or office. At this time, the information submitted is formatted and filtered at least once in accordance with the format required by the financial authorities. filtering). This is due to the fact that different institutions record information differently. Even if the relevant information is not processed in this process, it is very difficult to check whether the contents of the loan confirmation (eg, time stamp, quantity, amount, contract date, conclusion date) have been manipulated. This manipulation can occur not only in the audit process, but also in the usual balance sheet and short selling transactions. Even without intentional manipulation, there have always been error trades that result from unintentional people or system errors. There is no technical way to verify that a short selling transaction is a borrowed short selling transaction in the event of manipulation or error, so that if a borrowing short occurs, it will not be aware of it or will post-trade it. It also resulted in settlement risk.

Fifth, due to the problems mentioned above, financial supervisors / regulators are forced to take more stringent short selling regulations, and some countries, such as Korea, are strictly forbidden to trade short selling on the basis of hold confirmations. Sometimes. As a result, trading participants must pre-emptively contract or borrow unnecessary quantities, which can incur significant collateral and borrowing costs.

Sixth, in order to solve some of the problems mentioned above, some market participants have tokenized the loan confirmation letter and posted it on the blockchain to prevent unsold short selling through the generated token. If the token is generated by a centralized token issuer, the intent is that the token can be subsequently traded among market participants. However, this approach has a big problem of relying on third parties for token issuance and initial distribution. Issuance and trading of tokens are done through a centralized institution, making it difficult to prevent tampering or objectively verify transactions, rely on a single institution to prevent double payments for tokens, and sell the loan in the future through indiscriminate issuance of tokens. In the case of a loan or a non-rentable state, there is a big disadvantage that it can be very difficult to manage. Hacking risks are involved, as well as fraudulent transactions by forgery and tampering with centralized agencies. In addition to such counterfeiting, tampering, and hacking risks, it may not be a big risk for trading parties such as short sellers and lenders. none.

In addition, the above token method is very difficult to be able to track all transactions related to short selling. In other words, if a centralized token issuer issues tokens, it will only be included in subsequent transaction orders, and will not be included in any short-term process involving short selling (including short cover and redemption). Unlike locate IDs, which can only be used by borrowers, in the case of tokens that can make many transactions between an unspecified number, it is difficult to identify the corresponding short selling transaction or the entire short selling transaction.

In addition, as mentioned above, tokens are generated according to their own rules by a centralized token issuance or trading institution, without following the process of generating a locale ID by a lender or a prime broker. Thus, even if the token itself has a serial number, it is only a unique identification number arbitrarily generated by the token issuer, rather than the market. Therefore, it becomes difficult to identify some or all of the transactions included in the series of short selling processes.

The above-mentioned problems are difficult to match between the amount borrowed and the amount actually sold in the short sale trade cycle from borrowing to short selling. It is due to the limitations of the present technology that there is no binding medium and the present invention aims to solve these problems.

The present invention aims to solve all of the above-mentioned problems of the prior art.

In addition, the present invention, by using a distributed ledger-based locator ID, by analyzing the time point when the securities are rented or held, the number of securities that are rented or held and the time when the short selling is made and the quantity of the short-selling securities Another purpose is to verify the violation of the short selling regulations.

In addition, another object of the present invention is to detect or prevent naked short selling using a distributed ledger based locator ID.

It is another object of the present invention to track a transaction life cycle in which borrowing, short selling, counter buying, and repayment are made in real time using a distributed ledger based locator ID.

In addition, another object of the present invention is to ensure uniqueness of transactions by blocking duplicate lending of securities that may occur in short selling transactions using a distributed ledger based locator ID.

In addition, the present invention, by including a series of short selling transactions in the distributed ledger-based locator ID to generate irreversible information, to further improve the transparency of short selling transactions and to ensure the immutability of the transaction It is done.

It is another object of the present invention to reduce the transaction delay that occurs during the short selling process.

In addition, the present invention, by using the distributed ledger-based locator ID to enable the financial regulator to perform real-time auditing, thereby reducing the cost of monitoring and auditing the transaction participants of the financial regulator, Another aim is to improve the efficiency of monitoring and auditing.

The present invention also aims to reduce the regulatory reporting costs of market participants by allowing the short selling process to be real-time reporting to financial regulators.

In addition, the present invention reduces the risk that may arise due to borrowing after hold. Another purpose is to enable short selling transactions with a hold confirmation alone.

It is another object of the present invention to reduce the collateral and borrowing costs of borrowers incurred in the short selling process.

It is another object of the present invention to ensure atomicity of transactions by enabling atomic transactions that can no longer be divided between nodes on a network using distributed ledger-based locator IDs. It is done.

In addition, the present invention is to ensure the finality (finality) of the transaction by ensuring that each party's distributed ledger-based locator ID is updated through the aforementioned atomic transaction based on the agreement between the parties involved in the short selling. do.

On the other hand, such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types, described below, in accordance with the present invention.

First, the first management unit according to an embodiment of the present invention, when a rental or holding request for the securities occurs, the transaction information and the lender's side of the transaction information agreed by the lender and the borrower of the transaction information on the rental or holding The lender's device 110 may generate a distributed ledger based locale ID including irreversible arithmetic information calculated based on the information. Transaction information relating to the above rental or holding according to an embodiment of the present invention, the type of securities of the lender, the type of securities of the lender, the quantity of the securities of the lender, the lender, the borrower, the fee rate, the contract date, the date of conclusion, Information regarding at least one of dividends, rights relations, recall status, and proof of balance may be included. In addition, the lender's transaction information according to an embodiment of the present invention may include information about the digital signature of the lender.

Specifically, according to an embodiment of the present invention, the first management unit determines the transaction information to be agreed in order to perform an agreement with the borrower on the securities to be rented or held, at the borrower's device 110 to determine the borrower's device. And if the consent is made to the transaction information to be agreed by the borrower's device 120, it may be determined that the agreement between the lender and the borrower to the transaction information to be agreed is made. The lender's device 110 may generate a distributed ledger based locator ID including irreversible arithmetic information calculated based on the agreed transaction information and the lender's side transaction information.

In addition, the distributed ledger based locale ID according to an embodiment of the present invention may be generated by including, as irreversible calculation information, hash information calculated based on transaction information and loan side transaction information agreed by the lender and the borrower. .

For example, according to an embodiment of the present invention, the first management unit may include a random session key generated in the lender's device 110 based on a predetermined random number generation scheme and the above transaction information (specifically, the lender and The hash information corresponding to the transaction information agreed by the borrower and the lender's transaction information) may be generated as a distributed ledger based locator ID.

For another example, the first management unit according to an embodiment of the present invention, the random number and random session key generated on the basis of the predetermined random number generation method in the lender's device 110 and the above transaction information (specifically, , The hash information corresponding to the transaction information agreed by the lender and the borrower and the lender's transaction information) may be generated as a distributed ledger-based location ID.

For another example, according to an embodiment of the present invention, the first management unit, on the lender's device 110, the above transaction information (specifically, the transaction information agreed by the lender and the borrower and the lender's side transaction). After generating the distributed ledger based locale ID temporarily using the hash information corresponding to the information), the random number and random session key generated based on the predetermined random number generation method, the distributed ledger based locale ID generated above It is possible to generate a value calculated by hashing hash information corresponding to the above transaction information (specifically, transaction information agreed by the lender and borrower and transaction information of the lender) as a distributed ledger based locator ID. .
