Which categories of swap instruments were actually subject to the pre-trade mid-market mark disclosure requirement under §23.431(a)(3) prior to its elimination by the December 2025 CFTC final rule, and does 'eliminated in its entirety' mean the requirement was removed for all swap types?
The model extended "eliminated in its entirety" to mean the underlying disclosure obligations were removed, when the rule's actual operation was a paragraph-level restructuring — the price and compensation disclosure requirements were moved to different subsections of §23.431(a), not abolished. The model produced a product-agnostic exemption claim unsupported by the rule text, implying that a swap dealer's PTMMM obligations across its entire covered book were extinguished. That is a material mischaracterisation of what the amendment did.
This failure is a post-training calibration gap: the model interpreted 'eliminated in its entirety' as obligation extinguishment when the rule's operation was a paragraph-level reorganisation — the disclosure and compensation requirements moved subsections rather than disappearing. The model generated a product-agnostic exemption claim unsupported by the rule text, suggesting the calibration signal for 'eliminate/delete' in a rulemaking context does not adequately distinguish structural reorganisation from substantive removal. No cited sources were produced, indicating this was a training-reconstruction failure rather than a retrieval failure.
When the Legal function updates the bank's swap documentation playbook to reflect the PTMMM elimination under §23.431(a)(3), an AI tool that overstates the prior provision's product scope—extending its reach to cleared credit default swaps that were never subject to it—produces playbook guidance that mischaracterises the firm's pre-rule documentation posture. The actual amendment only removed the requirement for uncleared swaps, FX forwards, and FX swaps; cleared swaps were already outside PTMMM's scope.
A playbook built on the wrong baseline could lead trading desks to conclude a disclosure obligation has been removed for cleared CDS when that obligation never existed, creating confusion in any regulatory examination about whether the firm correctly tracked its obligations before and after the December 2025 rule—and whether its disclosure controls were accurately mapped to the instruments they cover.
