| **Description**                      | The correlation parameter between vega sensitivities within the same bucket, under the ‘Medium correlations’ scenario                       |
| **Variations**                       | [high-low](./high-low)                                                                                                                      |
| **Hierarchies required in the view** | [Crypto 2a Vega Double Sums](./crypto-2a-vega-double-sums), [Crypto 2a Buckets](./crypto-2a-buckets)                                        |

| **Notation**                         | $\rho_{kl}^{MediumCorr}$                                                                                                                    |

For each bucket, the factors $\rho\_{kl}$ are set based on whether k and l are the same or not - represented by the levels in the hierarchy **Crypto 2a Delta Double Sums**.
