BANK 4.3.8 Choosing between issuer and issue ratings

(1) If a banking business firm invests in an instrument with an issue-specific rating, the risk-weight to be applied to the instrument must be based on that rating.
(2) If the firm invests in an unrated instrument and the issuer of the instrument is assigned a rating that results in a lower risk-weight than the risk-weight normally applied to an unrated position, the firm may apply the lower risk-weight to the instrument but only if the claim for the instrument has the same priority as, or is senior to, the claims to which the issuer rating relates. If the instrument is junior to the claims to which the issuer rating relates, the firm must apply the risk-weight normally applied to an unrated position.
(3) If the firm invests in an unrated instrument and the issuer of the instrument is assigned a rating that results in a higher risk-weight than the risk-weight normally applied to an unrated position, the firm must apply the higher risk-weight to the instrument if the claim for that instrument has the same priority as, or is junior to, the claims to which the issuer rating relates.
