AI Hallucination on CPMI FPS Interlinking Governance for Lawyers in International

Misstated recommendation count, fabricated consultation respondents, and scoping drift on the CPMI October 2024 final report on FPS interlinking governance. Two frontier AI models tested by the RegLeg Brief Specialist Panel produced confident, citable answers across six distinct questions on the October 2024 CPMI final report on linking fast payment systems across borders that the regulator's own primary text in publication d223 directly contradicts. The audit covers the count and scope of the report's oversight recommendations, the named list of public consultation respondents in Annex 1, and the distinction between the interim publication d219 and the final publication d223.

For Lawyers working CPMI FPS interlinking governance matters, the failure pattern is operationally consequential. The audit tested six questions designed by the RLB Specialist Panel to mirror how lawyers, compliance officers, risk officers, operations leads, and board secretariats at FPS operators, hub entities, payment institutions, and banks actually use AI on this practice area: legal opinions on FPS interlinking arrangements, board memoranda on cross-border fast-payment governance, counsel notes for in-house teams at FPS operators and hub entities, and submissions to oversight authorities on interlinking-related risks. Each question is bound to verbatim regulator-issued primary substrate.

Across the six findings the AI subjects committed, in board-style and analyst-style deliverables, to approximately ten oversight recommendations (against the seven set out in d223 Section 5.2), to consultation-respondent lists of fifteen to twenty named organisations (against the seven specific respondents recorded in d223 Annex 1), and to a scoping treatment that places the single access point gateway model inside the report's recommendations (against d223 Section 2.2, which records that the single access point is not the focus of the report).

The findings are operationally consequential for legal teams, compliance teams, risk teams, operations teams, and board secretariats at payment institutions, banks, hub entities, and FPS operators whose practice touches the October 2024 CPMI final report. A board-level briefing memo that records the report as setting out approximately ten recommendations conflates the interim d219's ten considerations with the final d223's seven recommendations and embeds that confusion into the board's understanding of the oversight regime. A legal opinion that scopes a single access point arrangement inside the d223 recommendation set creates a falsifiable regulatory-interpretation error in a partner-level deliverable.

An analyst report that lists fifteen to twenty named consultation respondents (including fabricated organisation names) attributes positions and counts to stakeholders that the regulator's Annex 1 does not record.

  1. Misstated count of CPMI oversight recommendations in the October 2024 final report
    RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q001-Opus47

    For Lawyers advising on CPMI FPS interlinking governance, the AI's commitment to approximately ten oversight recommendations rather than the seven set out in CPMI d223 Section 5.2 lands directly in legal opinions on FPS interlinking arrangements, board memoranda for hub entities and FPS operators, counsel notes for in-house compliance teams, and submissions to oversight authorities. The wrong number anchors the team's planning on a fabricated compliance surface, drives over-implementation work against considerations carried over from the interim d219, and creates downstream inconsistencies between the team's d223 position and the recommendation set the regulator actually issued.

    The risk concentrates in legal opinions and board memoranda on cross-border fast-payment governance and FPS interlinking arrangements, where the count is a verifiable fact that supervisors, counterparties, and internal QC reviewers will check against the source.

  2. Single access point gateway model scoped into the report's recommendations (regulator records it as out of scope)
    RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q003-Opus47

    For Lawyers advising on CPMI FPS interlinking governance, the AI's commitment that the report's recommendations cover the single access point gateway model lands in legal opinions on FPS interlinking arrangements, board memoranda for hub entities and FPS operators, counsel notes for in-house compliance teams, and submissions to oversight authorities as a falsifiable scoping statement. CPMI d223 Section 2.2 and the Graph 2 caption record that the single access point and common platform models are not the focus of the report and are discussed only to a limited extent.

    The AI's framing pulls an out-of-scope model inside the recommendation set, distorting the team's view of which arrangements the framework actually binds and exposing legal opinions and board memoranda on cross-border fast-payment governance and FPS interlinking arrangements to a regulatory interpretation error that surfaces under supervisory review or counterparty challenge.

  3. Public consultation respondent list inflated and partly fabricated
    RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q005-Opus47

    For Lawyers advising on CPMI FPS interlinking governance, the AI's inflated and partly fabricated consultation-respondent list lands in legal opinions on FPS interlinking arrangements, board memoranda for hub entities and FPS operators, counsel notes for in-house compliance teams, and submissions to oversight authorities 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 legal opinions and board memoranda on cross-border fast-payment governance and FPS interlinking arrangements, 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.

  4. Conflated interim d219 considerations with final d223 recommendations

The wrong number anchors the team's planning on a fabricated compliance surface, drives over-implementation work against considerations carried over from the interim d219, and creates downstream inconsistencies between the team's d223 position and the recommendation set the regulator actually issued.
