Basel Framework: MAR22.39 first sentence

MAR22.39, in the CTP section, says the maturity scaling and offsetting rules apply to securitisations "(non-CTP)", a label copied from MAR22.30.

Consequence

Position: CTP index tranche long 1y+ and short 3M same tranche Reading a: Literal: maturity scaling applies only to non-CTP so CTP short is unscaled: net 0 Reading b: Intended: CTP scaled 1/4: net long 75% of notional Difference: 75 of 100

Proposed correction

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