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.
The December 2025 final rule eliminated the PTMMM provision in its entirety — but that provision had always applied only to uncleared swaps, FX forwards, and FX swaps. AI tools tested on this question extended 'eliminated in its entirety' to mean PTMMM no longer applies to cleared credit default swaps and other product types that were never within the provision's scope.
A memo stating that cleared swaps are now exempt from PTMMM — rather than accurately noting they were always outside scope — misconstrues the regulatory baseline and could cause a client to reach incorrect conclusions about what its documentation obligations were both before and after the rule change.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
