Delta
Download sample file: SBM_Delta_Sensitivities.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 FRTB Interpretation and Implementation guide:
This Delta file type is identified using the pattern: **/SB*_Delta_Sensitivities*.csv (as specified by sb.delta.sensitivities.file-pattern
).
This file is loaded using the SBM_Delta_Sensi 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.
- A row is added to the TradeBase store, to insert a new fact into the cube.
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.

It is expected that the risk factor name encompasses the definition of the risk factor per the FRTB specification ([MAR21.3] to [MAR21.14]), up to the sensitivity dates; this name is shared by all sensitivity dates. If not provided, it will be generated from the ‘Underlying’ column. For details on each risk factor, see the relevant section in the FRTB Interpretation and Implementation guide. | ||
GIRR | Name of underlying curve (e.g. UsdLibor3m). If not provided, then it is copied from Underlying. | |||||
CSR non-Sec | Name of issuer credit spread curve plus basis (Bond or CDS). If not provided, then it is calculated as (Underlying + Type). | “APPLE BOND”, “GOOGLE CDS” | ||||
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, then 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. | |||||
