(B) .— Rule of construction

the authority of the primary Federal payment stablecoin regulators, in prescribing standards under this paragraph, to tailor or differentiate among issuers on an individual basis or by category, taking into consideration the capital structure, business model risk profile, complexity, financial activities (including financial activities of subsidiaries), size, and any other risk-related factors of permitted payment stablecoin issuers that a primary Federal payment stablecoin regulator determines appropriate, provided that such tailoring or differentiation occurs without respect to whether a permitted payment stablecoin issuer is regulated by a State payment stablecoin regulator; or

any supervisory, regulatory, or enforcement authority of a primary Federal payment stablecoin regulator to further the safe and sound operation of an institution for which the primary Federal payment stablecoin regulator is the appropriate regulator.
