CCPPortfolioStressTestingDefinitionReportV01

auth.057.001.01

The CCPPortfolioStressTestingDefinitionReport message is sent from the central counterparty to the national competent authority. It is used to inform the national competent authority about how the central counterparty defines stress scenarios used to stress clearing member portfolios.

Message Construction

Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

CCPPortfolioStressTestingDefinitionReportV01 *-- "1..1" ScenarioDefinition1 : ScenarioDefinition
CCPPortfolioStressTestingDefinitionReportV01 *-- "0..1" SupplementaryData1 : SupplementaryData
  

Now, we will zero-in one-by-one on each of these building blocks.

ScenarioDefinition building block

Contains high level data on a stress scenario being applied to portfolios in order to calculate stress losses. Characteristics used to describe a hypothetical scenario designed to test the value of a portfolio of financial instruments under such hypothetical scenario. For comparison, see the ISO20022 official specification

ScenarioDefinition1 members

Member name Description Data Type / Multiplicity
Identification Identification of the stress scenario. GenericIdentification165 - Required 1..1
ScenarioType Indicates whether the scenario is based on a historical event or a hypothetical scenario. ScenarioType1Code - Required 1..1
StrategyStressType Indicates how the scenario stresses the curve. StrategyStressType1Code - Required 1..1
StressItem Information relating to the one / two major representative product(s). StressItem1 - Collection 1..2
Description Long description of the scenario. IsoMax2000Text - Optional 0..1

SupplementaryData building block

Additional information that cannot be captured in the structured elements and/or any other specific block. Additional information that can not be captured in the structured fields and/or any other specific block. For comparison, see the ISO20022 official specification

SupplementaryData1 members

Member name Description Data Type / Multiplicity
PlaceAndName Unambiguous reference to the location where the supplementary data must be inserted in the message instance. In the case of XML, this is expressed by a valid XPath. IsoMax350Text - Optional 0..1
Envelope Technical element wrapping the supplementary data. IsoSupplementaryDataEnvelope1 - Required 1..1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the CCPPortfolioStressTestingDefinitionReportV01 implementation follows a specific implementaiton pattern. First of all, CCPPortfolioStressTestingDefinitionReportV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, CCPPortfolioStressTestingDefinitionReportV01Document implements IOuterDocument. Because CCPPortfolioStressTestingDefinitionReportV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type CCPPortfolioStressTestingDefinitionReportV01.

    CCPPortfolioStressTestingDefinitionReportV01 --|> IOuterRecord : Implements
    CCPPortfolioStressTestingDefinitionReportV01Document --|> IOuterDocument~CCPPortfolioStressTestingDefinitionReportV01~ : Implements
    class IOuterDocument~CCPPortfolioStressTestingDefinitionReportV01~ {
        CCPPortfolioStressTestingDefinitionReportV01 Message
     }
  

Document wrapper for serialization

The only real purpose CCPPortfolioStressTestingDefinitionReportV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:auth.057.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using CCPPortfolioStressTestingDefinitionReportV01.ToDocument() method. The returned CCPPortfolioStressTestingDefinitionReportV01Document value will serialize correctly according to ISO 20022 standards.
