Delta Summary

Download sample file: SBM_Summary_Delta_Sensitivities_2018-09-25.csv

This file defines the Delta sensitivities, including a description of the risk factor. Full details on each risk factor are explained in the relevant section of the Atoti FRTB Interpretation and Implementation guide:

This Delta Summary file type is identified using the pattern: **/SBM_Summary*_Delta_Sensitivities*.csv (as specified by sbm.summary.delta.sensitivities.file-pattern). This file is loaded using the SBM_Delta_Sensi_Summary topic.

Normalization

The contents of this file are normalized and loaded into four stores during the ETL. For each row:

A description of the “underlying” is generated and added to the UnderlyingDescription store. This description is shared with Vega and Curvature.
A description of the risk-factor is generated and added to the RiskFactorDescription store.
The sensitivities are added to the Delta store.

Filling missing data

When the bucket field is omitted, it is filled from the Commodity, CSR, and Equities bucket files (as appropriate). To take advantage of this, the bucket files must be loaded before (or at the same time as) the Delta file.

When the bucket field is provided, some of the fields describing the underlying become optional. For CSR and Equities, these fields can be populated from previously loaded bucket description files.

Risk Class	Optional Fields When Bucket Provided	Bucket File	Bucket Description File
CSR non-Sec	CSRQuality, CSRSector	CSR non-Sec Buckets	CSR non-Sec Bucket Descriptions
CSR Sec non-CTP	CSRQuality, CSRSector	CSR Sec non-CTP Buckets	CSR Sec non-CTP Bucket Descriptions
CSR Sec CTP	CSRQuality, CSRSector	CSR Sec CTP Buckets	CSR Sec CTP Bucket Descriptions
Equity	EquityEconomy, EquityMarketCap, EquitySector	Equity Buckets	Equity Bucket Descriptions
Commodity		Commodity Buckets

note

The bucket is not sufficient to populate the CSRRating field for CSR non-Sec.

If not provided, it will be generated from the ‘Underlying’ column. For details on each risk factor, see the relevant section in the Atoti FRTB Interpretation and Implementation guide.
				GIRR	Name of underlying curve (e.g. UsdLibor3m). If not provided, then it is copied from Underlying.

				CSR Sec CTP	Name of issuer credit spread curve plus basis (Bond or CDS). If not provided, then it is calculated as (Underlying + Type).
				CSR Sec non-CTP	Name of issuer tranche, credit spread curve. If not provided, then it is calculated as (Underlying + Type).
				Equity	Name of equity plus type (spot or repo). If not provided, then it is calculated as (Underlying + Type).	“IBM SPOT”
				Commodity	Unique commodity name should include commodity name and delivery location. If not provided, it is calculated as (Underlying + Location).	“Brent Le Havre”, “WTI Oklahoma”
				FX	A currency pair (the exchange rate used in the calculation of the sensitivity). If omitted, it is generated from the underlying and FXCounterCurrency.
