The wording of Art. 325x(3) CRR raises the question whether the maturity scaling of gross JTD amounts with a floor of three months should apply only in cases where no offsetting is possible as the first sentence of the paragraph would suggest, or more generally to all gross JTD amounts with maturities of less than one year.
In the Basel framework, maturity weighting rules including the three-months floor (MAR 22.15 and 22.18) are applied to the JTDs of all positions, regardless of whether offsetting is possible in a specific case.
The ending of the second sentence of Art. 325x(3) is explaining the calculation of net JTD amounts and therefore implies that the second sentence is not limited to cases “where no offsetting is possible”.
