## Background
RELATED APPLICATIONS INFORMATION
This application claims priority under 35 U.S.C. §120 as a continuation-in-part to U.S. patent application Ser. No. 10/316,167, entitled, “SYSTEMS AND METHODS FOR AN ONLINE CREDIT DERIVATIVE TRADING SYSTEM,” filed Dec. 9, 2002, which is incorporated herein by reference in its entirety.


BACKGROUND OF INVENTION
1. Field of the Invention
The field of the invention relates generally to credit derivatives and more particularly to the transacting in credit derivatives in an online environment.
2. Background
Currently, conventional credit derivative markets comprise a user base of larger institutions. These large institutions use the credit derivative markets for a variety of reasons. For example, commercial banks, both domestic and foreign, can obtain significant economic, regulatory, and capital relief from selling credit risk in a credit derivative market. Commercial banks can also use the credit derivative markets to add credit risk to their portfolios as an alternative to the lending market. Insurers, which typically posses excellent credit evaluation skills, primarily use the credit derivative markets to take on credit risk for a premium. Investment management companies and Hedge Funds, or other investors, use the credit derivative markets to both take on and shed risk.
The dealer community represents some of the largest financial intermediaries in the world. The dealers tend to be large, multi-national institutions that make markets in credit derivatives. The scale and scope of each dealer's credit derivative business varies widely, with some dealers having extensive credit derivative operations, and other being occasional market participants. Thus, in conventional credit derivative markets, information flow is concentrated in a few dealers. Generally, the end users, such as those described above, transact through the dealers and not directly with each other. Often, information is scarce and incomplete as it relates to the buyers and dealers participating in the market, as is information concerning price and the risk associated with particular derivatives.
Dealers transact with other dealers via a broker market. A broker is an intermediary that transacts business between dealers. The brokers do not principal risk. Generally, information dissemination from the brokers is very inefficient. Further, the brokers business is limited to the dealers, because there is no meaningful contact between the brokers and end users.
There are other drawbacks to conventional credit derivative markets. One such draw back is that conventional credit derivative markets tend to be regionalized, e.g., with individual markets being localized by continent and/or time zones. For example, the U.S. credit derivative market tends to trade strictly in U.S. credit risk, while the European credit derivative market usually trades in European credit risk. Due to the manual and labor intensive nature of conventional credit derivative markets, it is very difficult for dealers to break down the localized nature of conventional credit derivative markets.
Another drawback is the high cost to transact in a conventional credit derivative market. Each dealer in a conventional credit derivative market tends to employ large intermediary infrastructure to facilitate the transactions. The size of the infrastructure leads to large transaction costs, which will remain as long as conventional credit derivative markets remain regionalized and controlled by just a few dealers. Further, because information is concentrated in the hands of a few large participants, conventional credit derivative markets are inefficient and illiquid. The illiquidity persists because for many of the largest participants, their only transactional outlet is through the dealers. Traditionally, another drawback is operational inefficiency that results from a lack of standardized documentation. The operational inefficiency is made worse by the fact that the documentation processes involved tend to be manual processes, which is also in part due top the lack of standardization.
Another drawback that will be mentioned here is the inefficient, fragmented, and disjointed distribution mechanisms of conventional credit derivative markets. When a market participant wants to transact, they will call one of a few dealers to ask for a price. Dealers usually will go through a broker at this point. Alternatively, the dealer will often call a limited number of other possible participants to determine if they are willing to transact. If the dealer determines that they are likely to find a willing participant at an acceptable spread, then the dealer will likely try to consummate the transaction, e.g., using a broker. Frequently, however, multiple dealers are calling the same potential participants trying to determine a willingness to transact. As a result, potential transactions are often selected out of the market because participants have few outlets, the dealer feels that the fee to consummate the transaction is too low, and/or the dealer will not principal the risk because they fear they will not be able to find a willing participant on the other side of the transaction. Consequently, while a few participants benefit from the economic inefficiencies of conventional credit derivative markets, many do not.
Another difficulty in trading credit derivatives occurs when a dealer or buyer desires to trade significant notional of credit derivatives. A desire for a large transaction can influence the market in a manner adverse to the trader.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is a diagram illustrating an example credit derivative trading system 100 in accordance with one embodiment of the systems and methods described herein. System 100 comprises a credit derivative authority 102 interfaced with a database 104. Database 104 can, as illustrated, actually comprise a plurality of databases depending on the embodiment. Credit derivative authority 102 is interfaced with a plurality of trader clients via terminals 108 through network 106.
In one embodiment, network 106 is the Internet; however, network 106 can be any type of wired or wireless Wide Area Network, wired or wireless Local Area Network, or even a wired or wireless Personal Area Network, or some combination thereof. Further, in certain embodiments credit derivative authority 102 and/or terminals 108 can be interfaced with network 106 via wired and/or wireless communication links, while in another embodiment, credit derivative authority 102 and/or terminals 108 are interfaced with network 106 via wired communication links.
In one embodiment, terminals 108 are computer terminals, such as desktop or laptop computers. In other embodiments, terminals 108 are handheld devices, such as handheld computers or personal digital assistants. It will be apparent, however, that terminals 108 can be any type of terminal configured to include the functionality required by the systems and methods described herein.
The term “authority” used to identify credit derivative authority 102 is intended to indicate that terminals 108 communicate with credit derivative authority 102 through the computing systems, hardware and software, associated with credit derivative authority 102. Thus, depending on the embodiment the term authority can refer to one or more servers, such as Internet or web servers, file servers, and/or database servers, one or more routers, one or more databases, one or more software applications, one or more Application Program Interfaces (APIs), or some combination thereof. Further, the computing system associated with credit derivative authority 102 can include one or more computers or computer terminals. To that extent, some of the same components that comprise the computer system associated with credit derivative authority 102 can also comprise terminals 108. An exemplary embodiment of a computer system that can comprise credit derivative authority 102 is described in more detail with respect to FIG. 7.
System 100 includes a standardize interface that allows the trader clients to define positions with credit derivative authority 102 for any of a plurality of credit derivatives regardless of the region, industry, etc. Credit derivative authority 102 is configured to then store the positions in database 104. Using the standardized interface, credit derivative authority 102 displays information related to the positions stored in database 104 to the trader clients via terminals 108. The trader clients are then able to define responsive positions, indicate a willingness to transact, and/or complete a transaction using the standardized interface. Thus, credit derivative authority 102 can replace the dealer-broker paradigm of conventional credit derivative markets and provides the trader clients with more outlets, greater liquidity, and more efficiency, all of which can help to lower transactional costs.
The standardized interface can comprise software components configured to run on credit derivative authority 102 as well as client software components configured to run on terminals 108. Thus, credit derivative authority 102 can work in conjunction with the client software running on terminals 108 to format and display information to the trader clients in a uniform manner and to receive input from the trader clients through terminals 108 in a manner that allows quick, easy, and efficient transactions. Certain features and aspects of the standardized interface are discussed more fully below.
FIG. 2 is a flow chart illustrating an example method of transacting in credit derivatives using system 100 in accordance with the systems and methods described herein. First, in step 202, credit derivative authority 102 receives information related to a reference entity's credit risk that is available for transaction. In other words, when a trader client wants to move credit risk in a certain reference entity, the trader client can access credit derivative authority 102 and make the information available along with an ask price.
In step 204, credit derivative authority saves the information in database 104 and in step 206, credit derivative authority 102 causes the information to be displayed to the rest of the plurality of trader clients via their terminals 108. Because the trader clients can access credit derivative authority 102 from anywhere in the world, the credit derivatives made available by credit derivative authority 102 are not limited by region or industry. Thus, the previously fragmented nature of credit derivative markets can be addressed. Moreover, credit derivative authority 102 is preferably configured to cause the information to be displayed in a compact and uniform manner to all of the trader clients regardless of the type of credit derivative. Moreover, credit derivative authority is preferably configured to update trader clients in real-time as new credit derivatives are defined within system 100.
As an example of the compact and uniform display of information, credit derivative authority 102 is configured in certain embodiments, to display the following for each credit derivative defined in system 100: a reference entity name, scheduled termination of the credit derivative, a debt level, a bid price, an ask price, a reference obligation, and a restructuring level. In other embodiments, credit derivative authority can also be configured to display the associated currency, a debt rating, and a debt type for each of the positions defined in system 100. Credit derivative authority 102 is configured, for example, to display the information using the standardized interface described above. Thus, credit derivative authority 102 retrieves the relevant information from database 104 and transmits it to a client application, or applications, running on terminals 108. The client applications then display the information in accordance with the systems and methods described herein.
FIG. 5A is a screen shot illustrating one example method of displaying the information on terminals 108 using a compact and uniform format. Thus, the display screen 500 includes a plurality of columns 502-518. As can be seen, column 502 comprises the names of various reference entities for which credit derivatives have been made available in system 100. Column 504 comprises the debt type associated with each reference entity in column 502. Column 506 comprises a debt rating associated with each reference entity in column 502. Although, as mentioned above, this column may or may not be included depending on the embodiment. Column 508 comprises the scheduled termination associated with the credit derivative for the reference entity in column 502. Column 512 includes the associated ask prices, while column 510 includes responsive bids. Thus, once bids are received, the information can be displayed in column 510. Columns 514 and 516, included in certain embodiments, comprise the bid and or ask prices associated with the particular trader client on whose terminal 108 display 500 is being displayed. Finally, column 518 comprises the associated currency.
FIG. 5B is a diagram illustrating another example method of displaying the information on terminals 108 using a compact and uniform format. As can be seen, the screen shot of FIG. 5B includes several columns 504 that include information about credit derivatives that can be traded. In addition to the names and other information related to the credit derivatives, each column 504 include a column 508 that includes market information. In this example, the market information simply includes a bid column 510 and an offer column 512. The display can also include a window 514 that includes information related to recent trades.
Once the information for a new credit derivative displayed in step 206, then bids can start to be received by credit derivative authority 102. This process is described below in relation to FIG. 3. Since the credit derivative market is a bilateral market, however, certain trader clients may not wish to deal with certain other trader clients in all, or certain, situations. Thus, in certain embodiments, credit derivative authority 102 is configured to receive information identifying trader clients with whom the trader client defining the new position is willing to transact, i.e., the trader client uses the standardized interface to provide identifying information to credit derivative authority 102 that identifies other trader clients with whom the trader client is willing to transact. Depending on the embodiment, the information includes the names of certain trader clients or defining characteristics of acceptable trader clients. Credit derivative authority 102 stores the identifying information in database 104 in step 210. The information is then used, as described below, in certain embodiments, by credit derivative authority 102 to help facilitate transaction between trader clients.
It should be noted that in certain embodiments, trader clients do not need to provide, or review, credit risk information related to the various trader clients. For example, in some embodiments, use of system 100 can be restricted to larger clients, or clients that are prescreened for credit risk.
In certain embodiments, the trader clients can customize their view of the information displayed. Thus, for example, in step 212 credit derivative authority 102 receives, from a trader client, information defining the customized view requirements of a trader client, i.e., using the standardized interface, a trader client inputs information defining a customized view. For example, in one embodiment, a trader client specifies certain regions of interest in step 212. Then, in step 214, credit derivative authority 102 retrieves from database 104 credit derivatives only for the indicated regions. These credit derivatives are then displayed, in step 216, on the trader client's terminal 108. Alternatively, a trader client can customize the trader client's view by specifying, in step 212, certain industries, certain reference entity names, certain credit duration, certain debt levels, certain spreads, i.e., the difference between the ask and bid prices, certain restructuring levels, etc., that the trader client is interested in. In an alternative embodiments, the credit derivatives can be sorted by geographic areas and/or sectors. Thus, a trader client can, in such embodiments, specify the area and/or sector of interest in step 212. In step 214 credit derivative authority 102 retrieves information for credit derivatives that meet the criteria input by the trader client.
In a process similar to view customization, trader clients can also preferably indicate certain alternative views that they are interested in. For example, in one embodiment, instead of indicating factors that define credit derivatives of interest, the trader client indicates, in step 212, an interest in certain historical information. Examples of historical information indicated in step 212 include, the historical spread information for a certain credit derivative, historical trades for the trader client, and historical transactions for a certain credit derivative. In certain embodiments, a relevant time period of interest is also indicated in step 212. Historical information conforming to the input criteria is then retrieved in step 214 and displayed in step 216.
For example, FIG. 6 is a screen shot illustrating a display 600 of historical transactions for a certain credit derivatives. As can be seen, display 600 includes columns 602-614. Column 602 comprises the date of the associated transaction, column 604 comprises the name of the reference entity involved, column 606 comprises the type of debt, column 608 comprises the scheduled termination of the credit derivative, column 610 comprises the identity of the buyer, column 612 comprises the price, column 614 comprises the name of the seller, column 616 comprises the notional amount of the transaction, column 618 comprises the associated currency, column 620 comprise the reference obligation, and column 622 comprise the status of the transaction. Of course, depending on the embodiment, some of the columns illustrated in FIG. 6 are not included in display 600.
FIG. 3 is a flow chart illustrating an example process by which a responsive position is received and handled in real-time by system 100. The example processes of FIG. 3 assume that the original position defined was an ask and, therefore, the responsive position is a bid. But the process is largely the same for the reverse situation as well. It should be noted that in certain embodiments, the time a bid or offer remains valid should be specified when the bid or offer is made. Additionally, in certain embodiments, the notional of the price should be specified.
The process begins in step 302, when a trader client inputs a bid, e.g., through their standardized interface, in response to a recent ask. In step 304, credit derivative authority 102 validates the bid, e.g., checks to ensure that the bid specifies a valid credit derivative. If the bid is not valid, then credit derivative authority 102 causes an error message to be displayed on the trader client's terminal 108 and allows the trader client to input another bid (step 302). If the bid is valid, then credit derivative authority 102 stores, in step 308, the bid information.
In one embodiment, credit creative authority 102 then checks the bid against information stored in database 104 to determine if the bid is the best bid. In other words, credit derivative authority 102 checks bid information stored in database 104 to determine if the bid is the highest bid for the associated credit derivative. If the bid is the best bid, then in step 312, credit derivative authority 102 updates all the trader clients with the new bid information. The update that occurs in step 312 is essentially in real-time. Thus, the trader clients are receiving updated information as the credit derivative market moves. Conversely, if the position defined in step 302 is an ask, then credit derivative authority 102 determines, in step 310, whether the ask is lower than the previous ask and updates the trader clients, in step 312, when it is determined that the ask is the lowest ask.
In certain embodiments, the latest ask or bid is broadcast to all trader clients regardless of whether it is the best, as indicated by the dashed line in FIG. 3. This allows the trader clients to see depth in the market.
FIG. 4A is a flow chart illustrating an example process for engaging in a transaction within system 100. The process begins in step 402 with a trader client indicating a desire to transact in response to a received updated position (step 312). For example, the trader client uses their standardized interface to indicate a desire to transact. In one embodiment, when credit derivative authority 102 receives the indication, it determines the ability of the trader client to transact on the associated credit derivative. This is where the information provided in step 208 can come into play if required. Thus, in step 404, credit derivative authority 102 determines, based on information stored in database 104, whether the trader client indicating a desire to transact is acceptable to the other party.
In one embodiment, if credit derivative authority determines that the trader client is not acceptable, then in step 406 credit derivative authority 102 presents the other party with the option to proceed. If the other party declines, then the transaction is not consummated. If, on the other hand, the other party is willing to continue, or if it is determined in step 404 that the trader client is able to transact, then the transaction proceeds. In other embodiments, as mentioned above, a determination as to whether a trader client is acceptable is not necessary.
The trader client can indicate a willingness to transact in step 402, by indicating a willingness to accept the terms associated with the new position or by indicating a willingness to negotiate with the other party. If the indication in step 402 is an acceptance, then the other party is notified of the acceptance in step 408 by credit derivative authority 102. If the indication of step 402 is of a willingness to negotiate, then the parties negotiate with each other in step 410. As will be described in more detail below, the parties can negotiate aided by the standardized interface and credit derivative authority 102. In an alternative embodiment, once the trader client indicates a willingness to transact in step 402, they call, or are contacted by, a broker associated with credit derivative authority 102 to negotiate and settle the transaction. In certain embodiments, direct negotiation as just described is not supported.
Once the transaction settles, all of the information associated with the transaction is stored by credit derivative authority 102 into database 104 in real-time, i.e., the information is stored as it passes back and forth between the parties and between the parties and credit derivative authority 102. Credit derivative authority 102 then updates the information displayed to the trader clients, again in real-time, in step 414, based on the transaction information.
In another embodiment, upon the settlement of the transaction, the trader can be prompted as to whether the trader desires to upsize the trade, that is increase the notional amount of the trade, that is the volume of the trade. At this point both parties are given a chance to request a trade of a larger notional amount, before knowing who their trading partner is. Upon determination of the largest notional amount agreed upon by both parties, the trade is completed at this notional amount.
FIG. 4B is a flow chart illustrating an example process for engaging in a transaction within system 100 where the trader is given the option to upsize the trade. The processing of the transaction described by FIG. 4B is similar to that of FIG. 4A except that upon notification of the acceptance in step 408 by credit derivative authority 102, the traders are given the opportunity to upsize the trade. If an upsize is agreed upon, the notional amount is increased in step 416 prior to credit authority 102 storing the transaction in step 412.
This can be beneficial when a trader desires to trade a notional amount that is greater than the standard or default amount. Generally, traders are hesitant to make an intention to trade more than the standard or default amount known, because this can result in a lower price for the credit derivative. Thus, if a default trade amount is 10 million dollars and a trader desires to trade 30 million dollars, the trader will often simply attempt to make three trades. With the volume upsizing process described above, and in more detail below, a trader desiring to trade a large notional amount of a credit derivative can trade that notional amount without making the market aware of his intention, thereby maintaining the value of his credit derivative.
FIG. 8 is a screen shot illustrating an example method of displaying a request to upsize a trade. Field 802 indicates that the original trade is completed in the notional amount shown at field 806. In this particular embodiment, the trader is given a predetermined interval of time to respond to the upsize prompt, which in this case is 20 seconds as shown at field 804. The trader can then elect to increase the trade to a higher notional amount by activating buttons 810, 812, or 814 depending on the size of the increase desired, or the trader can indicate no desired to increase by activating button 808. If both parties agree, the trade is upsized to that notional amount. In another embodiment, the prompting to upsize can repeat until one of the two trading parties no longer wishes to upsize at which point the largest amount agreed upon by both parties can be traded. In another embodiment, if the two parties both upsize but not to the same notional amount, the smaller of the two amounts can be taken as the agreed notional amount.
As mentioned above, system 100 comprises a standardized interface configured to make transacting in system 100 quick and efficient. Thus, the standardized interface allows each of the trader clients to interface with credit derivative authority 102 and view information on a plurality of credit derivatives that is displayed in a compact and uniform format. Example formats were described above, e.g., in relation to FIG. 5. As was also described, the standardized interface allows each of the trader clients to customize the trader client's view of the information displayed for the plurality of credit derivatives. This was explained, e.g., in relation to FIG. 6. Thus, the display of information can be customized using the standardized interfaced based any of the following: region, industry, a reference entity name, a credit duration, a debt level, a spread, a restructuring level, an ask price, reference obligation, and a credit rating.
In another embodiment, when there is sufficient activity in a particular credit derivative as determined either by the system or by the participants, the system can facilitate volume clearing of credit derivatives based on the most recently traded price. In overview, once the credit derivative has been traded, invited participants are invited to trade their credit derivatives during a set time interval. Those who desire to participate indicate the notional amount they desire to buy or sell. Once the time limit expires, the system determines which participants can trade and which buyers actually trade with which sellers, by matching similar trade amounts.
More specifically, when a trade is completed the price can be offered to invited participants by listing the trade in a “Volume Matching” display. FIG. 9 is a screen shot of an example of a Volume Matching display showing credit derivatives that the participant can trade. Column 902 represents the credit derivative to be traded and the price. Column 904 shows the time remaining to trade that credit derivative at that price. For example, in the first row, the credit derivative Commerzbank (CMZB) is available for trading at a price of 19 basis points (bps) for the next 18 seconds. Participants are invited based on criteria which is indicative of their desire to trade that credit derivative, such as placement of a bid in the trade current session or placement of a bid in a recent trade session involving the trade derivative.
FIG. 10 is a screen shot of an example of a method by which an interested participant can participate in volume clearing. Field 1002 shows the credit derivative and the price it is being traded at. The participant can select button 1004 and enter a notional amount into field 1006 that he desires to buy the credit derivative or alternatively the participant can select button 1008 and enter a notional amount into field 1010 that he desires to sell. The order is then placed by clicking on field 1012.
After the set time interval has expired, the orders can be filled according to the priority of the participant. The participant can be assigned a priority in the following order: the highest priority goes to current participants in the trade, the next highest priority goes to participants which are in the buyer or seller priority queues at the time of the trade, and finally, the remaining participants are prioritized on a first come first serve basis.
The orders are then matched to optimize as much as possible orders of the same size of the counterparties. By doing so, the number of trade tickets generated is minimized. Once the matching is completed a trade ticket is generated and each transaction can be completed similar to the manner described above for a single trade.
FIG. 11 is a table showing an example of how the trade matching works. In table 1102, there are four buyers and three sellers with their respective orders listed in the order of their priority. In matching table 1104, buyer 1 is matched with seller 3 because their notional amounts match. Furthermore, buyer 2 is matched with seller 1 because their notional amounts match. Since the remaining orders no longer match, the orders can be split. Buyer 3 having priority over buyer 4 is matched with seller 2. Since seller 2's order is larger than buyer 3's order, the remaining notional amount of seller 2 is available to buyer 4.
The standardized interface is further configured to allow each of trader clients to define credit derivative positions online and to update them quickly and efficiently. For example, in one embodiment, a trader client simply inputs the information that defines the credit derivative and their position, e.g., bid or ask price, and then updates the position with credit derivative authority 102 with a single “click”. The term “click” is intended to indicate that the user simply needs to use an input device, such as a mouse, to select text, a button, or an icon. Moreover, the trader can use this simple process to update a position anytime, and all of the other trader clients will be updated automatically in real-time.
The standardized interface, in certain embodiments, is also configured to allow the trader clients to, at anytime, render inactive all or some of the trader clients defined positions with a single click. Trader clients can also reactivate some or all of their inactive positions using a single click, whenever they decide to do so. Trader clients can also increase the time for which a price remains tradeable. The other trader clients are then automatically updated, based on the deactivation and reactivation of positions, in real-time.
In certain embodiments, credit derivative authority 102 is configured to facilitate communication with trader clients via their terminals 108. This communication can be between trader clients, i.e., between terminals 108, and/or between trader clients and credit derivative authority 102, i.e., between terminals 108 and credit derivative authority 102. Thus, the standardized interface includes an electronic messaging tool, such as email or instant messaging. The trade clients input and send messages using the electronic messaging tool. The messages are received by credit derivative authority 102 and forwarded to the correct terminal 108, when required. The messaging capability is used for example, to facilitate negotiations and/or settlement of transactions between trader clients. Thus, in some instances the messages are between terminals 108 and include negotiation information. In other instances, the messages are between credit derivative authority 102 and a terminal 108 and include settlement information.
FIG. 7 is a logical block diagram illustrating an example embodiment of a computer system 700 that is, for example, included in the computer system that comprises credit derivative authority 102. As will be understood, some type of processing system is always at the heart of any computer system, whether the processing system includes one or several processors included in one or several devices. Thus, computer system 700 of FIG. 7 is presented as a simple example of a processing system. In the example of FIG. 7, computer system 700 comprises a processor 710 configured to control the operation of computer system 700, memory 704, storage 706, a network interface 708, a display output 712, a user interface 714, and a bus 702 configured to interface the various components comprising computer system 700.
Processor 710, in one embodiment, comprises a plurality of processing circuits, such as math coprocessor, network processors, digital signal processors, audio processors, etc. These various circuits can, depending on the embodiment, be included in a single device or multiple devices. Processor 710 also comprise an execution area into which instructions stored in memory 704 are loaded and executed by processor 710 in order to control the operation of computer system 700. Thus, for example, by executing instructions stored in memory 704, processor 710 causes credit derivative authority 102 to execute the steps described above.
Memory 704 comprises a main memory configured to store the instructions just referred to.
