Finding#3 — PTMMM elimination scope overstated to include cleared swaps

What the RLB Specialist Panel found
Question (paraphrased to protect IP)

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?

RLB's analysis

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.

AI Head's analysis — what weakness in the AI model caused this

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.

Impact for Lawyers in the United States advising on the Revisions to Business Conduct and Swap Documentation Requirements for Swap Dealers and Major Swap Participants

Advising a swap dealer that PTMMM disclosure is now eliminated for cleared CDS — on the basis that the rule eliminated the requirement 'in its entirety' — overstates the change. Cleared swaps were already outside §23.431(a)(3)'s scope before the December 2025 rule; the elimination restructured the provision for uncleared swaps, FX forwards, and FX swaps.

An opinion that presents the PTMMM repeal as product-agnostic would misrepresent the pre-existing regulatory baseline, potentially causing a client to attribute compliance relief to the new rule that was already present under the prior framework — a material misstatement in any regulatory history analysis or sign-off letter.
