Article 26
Assessment of credit spread risk factors
1. When assessing an institution’s compliance with the requirements set out in Article 325bh(1) of Regulation (EU) No 575/2013 in relation to the modelling of credit spread risk, competent authorities shall:
(a) |
require the institution to provide a list of all issuers’ credit spreads curves and credit indices towards which the institution’s portfolio is sensitive, and the risk factors used to model the associated risk; |
(b) |
require the institution to provide a sensitivity analysis of its portfolio towards each of the issuers’ credit spreads curves and credit indices referred to in point (a); |
(c) |
verify whether, where the risk in an issuer credit spread is modelled as a sum of a systematic risk factor as referred to in Article 3(3) of Delegated Regulation (EU) 2022/2060 and an idiosyncratic risk factor, the volatility generated by shocking those factors reflects the volatility observed for that issuer credit spread; |
(d) |
verify whether the basis risk between issuers is captured by either modelling the issuers’ credit spreads directly or by means of a basis risk factor, and whether the basis between different positions referencing to the same issuer is monitored and, when material, included in the internal risk-measurement model; |
(e) |
assess whether the risk in changes in credit spread curves is duly captured as required by Article 29 of this Regulation; |
(f) |
assess whether vega risk related to credit spread risk is duly captured as required by Article 30 of this Regulation. |
For the purposes of point (c), competent authorities may, where appropriate, compare the volatility of the shocks applied to the issuer credit spread, as resulting from the systematic and idiosyncratic risk factors, with the volatility observed for that issuer credit spread.
2. By way of derogation from paragraph 1, point (a), competent authorities may require an institution to provide the information referred to in that point for the most relevant credit spreads curves and credit indices only, and perform the assessment set out in that paragraph 1 on those data.
