What trading venues does CFTC Staff Letter 25-49 specifically address for the treatment of intended-to-be-cleared swaps, and which prior no-action letter does it supersede in its entirety?
The model replaced the letter's actual geographic and venue-specific scope — Eligible UK Trading Venues — with a generic ITBC framing covering any swap execution facility or designated contract market. This substitution transforms a jurisdiction-specific no-action letter into a general statement about ITBC swap treatment, which is both factually wrong and operationally consequential: a swap dealer relying on this output to assess coverage for a UK venue transaction would not be covered by the letter the model described. The cited source is a law-firm commentary that did not contain the precise venue restriction the letter establishes.
This failure points to a scope-restriction suppression pattern in how the model handles CFTC staff letters: the training corpus appears to weight the interpretive general statement (ITBC swap treatment) more heavily than the bounding clause (Eligible UK Trading Venues only), so the model reproduces the general statement as the letter's full coverage. The retrieval layer's top result — a law-firm summary — did not contain the precise venue restriction, and the model did not flag the gap between its training-derived framing and the retrieved source.
AI tools we tested described CFTC Staff Letter 25-49 as covering ITBC swaps on U.S. SEFs and DCMs — directly contradicting the letter's actual scope, which is limited to Eligible UK Trading Venues authorised by the FCA. When challenged, the AI retracted its answer and acknowledged the error.
For a Compliance team advising a rates or credit desk on whether execution through a UK MTF or OTF qualifies for the letter's relief, an AI answer that maps the relief onto U.S. venues is operationally backwards: it fails to extend relief the firm actually qualifies for, while simultaneously suggesting relief applies to venues outside the letter's scope. The CFTC's examination posture on cross-border swap execution compliance is well-established; a Compliance memo based on the AI's initial characterisation would be incorrect on its face.
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.
