AI Summary of Article 325af Intra bucket correlations for general interest rate risk

This document outlines the correlation parameters applicable to the weighted sensitivities of general interest rate risk factors. Within the same maturity bucket, when comparing two sensitivities linked to different curves, a high correlation of 99.90% (ρkl) is mandated. For sensitivities associated with the same curve but differing maturities, the correlation will adhere to a specified formula.

Moreover, when sensitivities from different curves and maturities are considered, the correlation is derived from the previous parameter, adjusted to 99.90%. Notably, correlation levels between interest and inflation risk factors are established at 40%, while interactions between cross-currency basis risk factors and general interest rate risks are set at 0%.

Article 325af Intra bucket correlations for general interest rate risk

1. Between two weighted sensitivities of general interest rate risk factors WSk and WSl within the same bucket, and with the same assigned maturity but corresponding to different curves, correlation ρkl shall be set at 99,90 %.

2. Between two weighted sensitivities of general interest rate risk factors WSk and WSl within the same bucket, corresponding to the same curve, but having different maturities, correlation shall be set in accordance with the following formula:

3. Between two weighted sensitivities of general interest rate risk factors WSk and WSl within the same bucket, corresponding to different curves and having different maturities, the correlation ρkl shall be equal to the correlation parameter specified in paragraph 2, multiplied by 99,90 %.

4. Between any given weighted sensitivity of general interest rate risk factors WSk and any given weighted sensitivity of inflation risk factors WSl, the correlation shall be set at 40 %.
