Abstract
Description
The present invention relates to a method for monitoring quantitative suitability and performing statistical verification for LGD / EAD input to the risk amount calculation of the BIS.
The BIS ratio is the bank's equity ratio as set forth by the International Settlement Bank, which represents the bank's equity and identifies risk-weighted assets (for example, assets that are at risk of loss, such as loans and securities investments). To calculate. Therefore, a system for properly estimating and statistically verifying LGD / EAD used for calculating the amount of risk in BIS is required. However, in the past, the system is only performing one-time verification using Excel.
The technical problem to be achieved by the present invention is to provide a method and system that can monitor the adequacy of LGD / EAD input to the risk amount calculation of the BIS, and can perform statistical verification through automation.
In order to achieve the above technical problem, an example of the quantitative conformity verification method of the LGD / EAD according to the present invention, based on the exposure, collateral and collection history of the default borrower for a certain period of time, by mortgage type, borrower type, Classifying segments by product type; Calculating the recovery rate, recovery rate, additional usage rate, and now conversion rate for each segment by the default year; And determining an expected value to be applied when calculating the BIS ratio based on the calculated value, and comparing the actual value with the actual value.
According to the present invention, the adequacy of the LGD / EAD input factors can be monitored at all times. In addition, it is possible to enhance work efficiency and enhance execution ability by automating statistical verification tasks, and to develop self-development of algorithms for calculating thresholds of Z distribution, T distribution, and F distribution, and to set the upper limit or the lower limit automatically for estimation Can support verification work.

2 is a diagram illustrating an example of an LGD / EAD quantitative conformity verification process according to the present invention, and
3 is a flowchart of an example of a LGD / EAD quantitative conformity verification method according to the present invention.
Hereinafter, with reference to the accompanying drawings will be described in detail the LGD / EAD quantitative conformity verification method according to the present invention.
1 is a diagram illustrating an example of an LGD / EAD quantitative conformity verification system according to the present invention.
Referring to FIG. 1, the LGD / EAD quantitative conformity verification system includes a

The
For example, as a parameter value for estimating the LGD, values such as a recovery rate, a recovery rate, a credit recovery rate, and a default asset may be used. Here, the recovery rate indicates the rate at which companies, small businesses, and individuals recover from the default, and the recovery rate is identified through auction data on real estate, the recovery rate of deposit collateral, and the recovery rate of guarantee collateral. As a parameter value for estimating the EAD, an additional utilization rate and an egg conversion rate may be used. There may be several parameter elements to estimate LGD and EAD.
The
2 is a diagram illustrating an example of an LGD / EAD quantitative conformity verification process according to the present invention.
Referring to FIG. 2, as source information for the LGD / EAD quantitative conformity verification process, the borrower's default information 200,
The source information is processed to generate an intermediate table classified by collateral type, borrower type, and product type, and then identify various parameters for calculating the expected values (eg, LGD, EAD) that are applied when calculating the BIS ratio.
More specifically, based on the
Based on the
Each parameter obtained for calculating the BIS ratio includes a recovery rate (224), a credit recovery rate (226), a product (e.g., credit or draft) (228), real estate collateral (230), guarantee collateral (232),
3 is a flowchart of an example of a LGD / EAD quantitative conformity verification method according to the present invention.
Referring to FIG. 3, the system obtains and loads various kinds of default information of the default borrower (S300). The system classifies the information of the past borrower for a certain period of time into segments such as collateral type, borrower type, and product type (S310), and then assigns parameters such as recovery rate, recovery rate, additional usage rate, and payment rate for each segment to the default year. It calculates each (S320). The system then uses the calculated parameters to make estimates of the various values applied to the BIS ratio calculation, and then monitors the actual values actually realized and performs statistical verification (S330).
The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
So far I looked at the center of the preferred embodiment for the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
