Abstract

Claims (77)

1. A method, comprising:

receiving and storing, at a non-transitory computer readable medium, a plurality of data associated with a plurality of financial instruments within a portfolio;

calculating, using a processor communicatively coupled to the non-transitory computer readable medium, a maximum risk margin for each of a plurality of risk factors, wherein the maximum risk margin for each of the plurality of risk factors is determined based on the plurality of data, wherein the plurality of risk factors include a convergence and divergence risk factor, and wherein the calculation of the maximum risk margin includes:

classifying the plurality of financial instruments within the portfolio according to tenor:

calculating a periodic change in spreads for each tenor;

identifying a largest periodic change in spreads; and

calculating the convergence and divergence risk factor based on the largest periodic change in spreads; and

calculating, using the processor, a total multi-factor risk margin based on the maximum risk margin for each of the plurality of risk factors.

2. The method of claim 1 , wherein the plurality of risk factors include a systematic risk factor, the method comprising:

identifying time series spread data of at least one index from the plurality of data;

calculating a plurality of absolute periodical changes from the time series spread data; and

determining the systematic risk shock factor according to a statistical analysis of the plurality of absolute periodical changes.

3. The method of claim 1 , wherein the plurality of risk factors include a curve risk factor, the method comprising:

selecting a curve factor based on a type of each of the plurality of financial instruments within the portfolio;

determine a plurality of curve charges based on the curve factor and a notional amount for each of the plurality of financial instruments within the portfolio; and

summing the plurality of curve charge to determine the curve risk factor.

4. The method of claim 1 , wherein identifying the largest change in spreads comprises:

selecting a sample regression line having a predetermined slope;

plotting a plurality of pairs of spread changes;

calculating a distance from each of the plurality of pairs of spread changes; and

selecting the distance spaced farthest from the sample regression line.

5. The method of claim 1 , wherein the plurality of risk factors includes an idiosyncratic risk factor, the method comprising:

selecting a maximum loss of a jump to health value and a jump to default value for each of the plurality of financial instruments within the portfolio; and

summing the maximum loss for each of the plurality of financial instruments within the portfolio to determine the idiosyncratic risk factor.

6. The method of claim 1 , wherein the plurality of risk factors include a liquidity risk factor, the method comprising:

selecting an anchor financial instrument from the plurality of financial instruments;

generating a liquidity profile from comparisons of a ratio of the bid-ask spread for each of the plurality of financial instruments to the anchor financial instrument; and

calculating the liquidity risk factor based on the liquidity profile, a duration adjustment, and a present value factor.

7. The method of claim 1 , further comprising:

determining a shock value for each of the plurality of risk factors within a multi-factor risk model, wherein the maximum risk is a function of the shock value associated with each of the plurality of risk factors; and

sending data indicative of the total multi-factor risk margin to a device.

8. A method, comprising:

receiving and storing, at a non-transitory computer readable medium, a plurality of data associated with a plurality of credit default swaps within a portfolio;

calculating, using a processor communicatively coupled to the non-transitory computer readable medium, a plurality of maximum risk margins based on at least a portion of the received plurality of data, wherein the plurality of maximum risk margins include a convergence and divergence risk margin, and wherein the calculation of the plurality of maximum risk margins comprises:

classifying the plurality of data according to tenor;

calculating a periodic change in spreads for each tenor;

identifying a largest periodic change in spreads;

calculating the convergence and divergence risk factor based on the largest periodic change in spreads;

calculating, using the processor, a total multi-factor risk margin based on the plurality of maximum risk margins; and

sending data indicative of the total multi-factor risk margin to a device.

9. The method of claim 8 further comprising:

calculating a maximum systematic risk margin based on a first portion of the received plurality of data; and

calculating a maximum curve risk margin based on at least a second portion of the received plurality of data.

10. The method of claim 9 further comprising:

calculating a maximum sector risk margin based on at least a fourth portion of the received plurality of data; and

calculating a maximum idiosyncratic risk margin based on at least a fifth portion of the received plurality of data.

11. The method of claim 10 further comprising:

calculating a maximum liquidity risk margin based on at least a sixth portion of the received plurality of data; and

calculating a maximum basis risk margin based on at least a seventh portion of the received plurality of data.

12. An apparatus, comprising:
