1.Between two sensitivities WSk and WSl, resulting from risk exposures assigned to sector buckets 1 to 10, 12 to 18 and 20 of Article 383s(1), Table 1, the correlation parameter ρkl shall be set as follows:
\rho_{kl} = \rho_{kl}^{(\mathrm{tenor})} \cdot \rho_{kl}^{(\mathrm{name})} \cdot \rho_{kl}^{(\mathrm{quality})}
where:
\rho_{kl}^{(\mathrm{tenor})} | shall be equal to 1 where the two vertices of the sensitivities k and l are identical, otherwise it shall be equal to 90 %; |
\rho_{kl}^{(\mathrm{name})} | shall be equal to 1 where the two names of sensitivities k and l are identical, 90 % if the two names are distinct but legally related, otherwise it shall be equal to 50 %; |
\rho_{kl}^{(\mathrm{quality})} | shall be equal to 1 where the two names are both in buckets 1 to 10, are both in buckets 12 to 18, or are both in bucket 20, otherwise it shall be equal to 80 %. |
2.Between two sensitivities WSk and WSl, resulting from risk exposures assigned to sector buckets 11 and 19, the correlation parameter ρkl shall be set as follows:
\rho_{kl} = \rho_{kl}^{(\mathrm{tenor})} \cdot \rho_{kl}^{(\mathrm{name})} \cdot \rho_{kl}^{(\mathrm{quality})}
where:
\rho_{kl}^{(\mathrm{tenor})} | shall be equal to 1 where the two vertices of the sensitivities k and l are identical, otherwise it shall be equal to 90 %; |
\rho_{kl}^{(\mathrm{name})} | shall be equal to 1 where the two names of sensitivities k and l are identical and the two indices are of the same series, 90 % if the two indices are the same but of distinct series, otherwise it shall be equal to 80 %; |
\rho_{kl}^{(\mathrm{quality})} | shall be equal to 1 where the two names are both in bucket 11 or both in bucket 19, otherwise it shall be equal to 80 %. |
