Basel Framework: MAR50.68 Table 10 vs MAR50.66 Table 8

MAR50.68 Table 10 labels buckets 8, 9 as IG and 16 as HY/NR, contradicting the credit-quality assignment in MAR50.66 Table 8.

Consequence

Position: HY sovereign reference name, bucket 8 Reading a: Row label read literally: bucket 8 is IG, so IG weight 2.0% is stated but bucket is not IG Reading b: Table 8: bucket 8 is HY/NR, weight 2.0% Difference: no numeric difference for bucket 8; for bucket 16 label 'HY/NR' conflicts with IG

Proposed correction

Clarify or correct the cited passage so that the rule and its references give one result for the stated case.
