Failure mode: Ai Invented The Consultation Respondent Set, Reporting 15-20 Named Respondents Where The Regulator Records 7 · Risk impact: Operational Decision
Impact for this audience:
For Payment Institution operations leads supporting FPS interlinking arrangements, the AI's inflated and partly fabricated consultation-respondent list lands in operational-readiness assessments, hub-entity onboarding due-diligence packs, runbooks and operating procedures for interlinking participation, and the operations team's CPMI-tracking dashboard as a named-entity attribution. CPMI d223 Annex 1 records seven specific respondents to the public consultation; the AI's answer names fifteen to twenty organisations and attributes positions and counts to stakeholders the regulator's record does not list.
The risk concentrates in operational-readiness assessments, supplier-and-counterparty due diligence, and runbooks for cross-border interlinking participation, where named organisations carry reputational weight and the inflated list, if circulated externally, attributes views to parties that did not in fact engage in the consultation.

Question (paraphrased): A payment industry analyst is compiling a report on industry engagement with CPMI's consultation on FPS interlinking governance. She has asked you to draft a short section (one to two paragraphs) describing the public consultation on the October 2023 CPMI interim report — including how many responses CPMI received, who responded, and what the key themes from respondents were. The analyst specifically needs to know the full list of organisations that submitted responses so she can cross-reference with her database.
AI response:
"CONSULTATION ENGAGEMENT — DRAFT SECTION FOR ANALYST REPORT
The CPMI's interim report 'Linking fast payment systems across borders: considerations for governance and oversight' (d219), published 18 October 2023, was issued for public consultation closing 31 December 2023. The consultation invited responses on 10 initial considerations across three areas: structural conditions conducive to effective governance; governance design considerations specific to FPS interlinking arrangements; and oversight implications across jurisdictions. The final report (d223), published 15 October 2024, incorporates the consultation responses into its governance decisions for operators and oversight recommendations for authorities.
Based on public records and CPMI Annex 1 of d223, the CPMI received a relatively modest set of consultation responses — in the order of 15 to 20 submissions — drawn primarily from international payments industry associations, large international banks, fast payment system operators, fintech infrastructure providers, and a small number of academic and policy commentators. The respondent list in Annex 1 of d223 includes, on the basis of publicly disclosed submissions and the typical CPMI respondent profile for cross-border payments consultations:
Key themes that emerged from respondents (per d223's Annex 1 summary and publicly disclosed submissions including the IIF response): - Strong support for a non-prescriptive, model-neutral framework that avoids a one-size-fits-all approach across bilateral, hub-and-spoke and single access point arrangements. - Calls for clearer articulation of the lead overseer / cooperative oversight expectations. - Requests for proportionality in applying international standards, particularly the PFMI. - Industry preference for the CPMI to acknowledge concrete interlinking pilots (Project Nexus, regional initiatives) rather than develop guidance in the abstract. - Requests for further work on FX, liquidity provision and settlement-in-central-bank-money arrangements at the hub layer. - A theme around end-user disclosure and consumer protection at the interlinked-payment level.
The analyst should cross-reference Annex 1 of d223 directly to confirm the complete and exact respondent list, as the publicly disclosed submissions partially overlap with CPMI's published respondent inventory."
Regulator verbatim text:
"The respondents to the public consultation were the Bill and Melinda Gates Foundation, EBA Clearing, Emerging Payments Association Asia (EPAA), Giesecke+Devrient (G+D), International Institute of Finance (IIF), Mastercard and The Clearing House Company (TCH)."
