FRTB Accelerator Cube GuideGIRR Vega Risk Position
| Description | The bucket-level capital charge for GIRR vega, also known as risk position, under the 'Medium correlations' scenario |
|---|---|
| Variations |
|
| Reference | [MAR21.4] |
| Notation | $K_b MediumCorr$ |
| Formula | $$K_{b} =\sqrt{max \left( 0, \sum _{k\in b} WS_{k}^{2} +\sum _{k\in b}\sum _{l\in b, l\neq k}\rho_{kl}\cdot WS_k \cdot WS_l\right)}$$ |
The measure requires having hierarchy(ies) in the view: [Buckets].[GIRR Buckets].
