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.
AI tools we tested interpreted 'eliminated in its entirety' to mean PTMMM disclosure no longer applies to any swap type under §23.431 — including cleared CDS. In fact, the December 2025 final rule deleted the §23.431(a)(3) container provision and moved price and compensation disclosure obligations into adjacent paragraphs; cleared swaps were already outside PTMMM's scope before the amendment. A Compliance team drafting updated disclosure procedures for a multi-product swap desk that runs both uncleared and cleared products needs to preserve disclosure obligations for the uncleared book precisely.
An AI-generated overclaim of the PTMMM elimination embedded in Compliance policy documentation creates a control gap that regulators and internal audit can both identify — and that trading desk reliance on that documentation would then propagate into live execution.
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.
