| Reference | [MAR21.94] |
| Notation | $rho_kl MediumCorr$ |
| Formula | $$\rho_{kl}=min\left [\rho_{kl}^{DELTA} \cdot \rho_{kl}^{option\ maturity};1 \right ]$$ |
Correlation parameter $\rho_{kl}$ between vega sensitivities within the same bucket (‘medium’ correlation scenario).
The measure requires having hierarchy(ies) in the view: [Double Sums].[CSR Sec non-CTP Vega Double Sums], [Buckets].[CSR Sec non-CTP Buckets].
