AI Hallucination on CPMI FPS Interlinking Governance for Operations teams at Payment Institutions firms in International

Payment Institutions Operations teams: documentation and reporting gaps possible from AI reading of CPMI FPS Interlinking Governance 2024

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 Operations teams at Payment Institutions 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 legal, compliance, risk, operations, and board-secretariat teams at payment institutions, hub entities, and banks participating in fast payment system interlinking arrangements actually use AI on this practice area: operating manuals for FPS interlinking arrangements, service-level agreement drafting against the d223 recommendation set, incident-management playbooks for interlinking links, and consultation-engagement briefings on the d223 outcome. 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.

The audit's six findings are published with immutable RLB Citation IDs.

Executive Summary

Operations teams at Payment Institutions are increasingly using AI to operationalise the October 2024 CPMI final report on FPS interlinking governance, recorded as publication d223. Two frontier AI models tested by the RLB Specialist Panel produced confident, citable answers on the count and scope of the report's oversight recommendations, the named list of public consultation respondents, and the distinction between the interim d219 and the final d223 that the regulator's own primary text directly contradicts.

This cell collects the relevant hallucination findings on the October 2024 CPMI final report, organised for operations teams at payment institutions working on FPS interlinking matters. Across the relevant findings the AI subjects produced confident, citable answers on questions ranging from the count of oversight recommendations to the named list of Annex 1 consultation respondents. Every finding in this cell is bound to verbatim regulator-issued source text held as primary substrate by the RLB Specialist Panel.

How AI gets this regulation wrong

The findings in this cell cluster around two failure shapes that recur across the October 2024 CPMI final report on FPS interlinking governance: inference drift on counts and named-entity lists (oversight recommendations, consultation respondents), and misstated rules on the scoping language that places certain cross-border payment models inside or outside the report's recommendation set. In each case the AI subject committed to a specific, citable, verbatim-looking answer where the regulator's own primary text in d223 records a different position.

What that means for your practice

Operations teams at Payment Institutions commonly use AI to: operating manuals for FPS interlinking arrangements, service-level agreement drafting against the d223 recommendation set, incident-management playbooks for interlinking links, and consultation-engagement briefings on the d223 outcome.

The risk concentrations across the 3 findings in this cell are summarised in the table below. Each entry maps the failure shape to its practical implications for Operations teams at Payment Institutions working on CPMI FPS interlinking governance matters.

When this affects Operations teams at Payment Institutions

Operations teams at Payment Institutions encounter the October 2024 CPMI final report when operationalise board-level briefings, drafting oversight policy notes, preparing legal or operational opinions on cross-border interlinking arrangements, and producing stakeholder-engagement materials on the d223 outcome.

The specific findings in this cell map onto the most common questions Operations teams at Payment Institutions put to an AI tool on the October 2024 CPMI final report. First, what the count and scope of the report's oversight recommendations are. Second, which cross-border payment models the report's recommendations actually cover. Third, who the report's consultation respondents were. The AI subjects in this audit produced verbatim-looking answers on each that the regulator's own primary text in d223 directly contradicts.

Aggregate impact

The 3 findings in this cell, taken together, describe a specific pattern that Operations teams at Payment Institutions should expect to encounter when AI tools are used on the October 2024 CPMI final report. The AI subjects in this audit committed, with no hedging, to verbatim-looking answers on counts (oversight recommendations), named-entity lists (consultation respondents), and scope questions (which cross-border payment models the recommendations cover). In each case the AI subject had access to the regulator's source text at query time, and in each case the AI's output diverged from the source text on a specific, testable fact.

The pattern across the 3 findings points to a generation behaviour that Operations teams at Payment Institutions should treat as a near-certain failure mode in this practice area. When the question asks for a count of recommendations, a named list of consultation respondents, or a scoping statement on which payment models the report's recommendations cover, the AI subjects produced a coherent, structurally plausible answer with the wrong number, with fabricated respondent names, or with the wrong scoping treatment.

None of the AI outputs in this cell flagged uncertainty, recommended source verification, or declined to commit; each output reads as if the AI had directly retrieved the regulator's text.

For practising teams, the implication is that AI-assisted research on the CPMI October 2024 final report on FPS interlinking governance cannot be relied on for: the count of the oversight recommendations; the named list of consultation respondents; the scoping statement on the single access point and common platform models; or the distinction between the interim d219's ten considerations and the final d223's seven recommendations. Each of these is a question type the AI handles in a confident, fluent register, and each is a question type where the AI in this audit was wrong in ways the regulator's own text resolves.

What the AI got wrong

Finding 1: Misstated count of CPMI oversight recommendations in the October 2024 final report

Citation ID: RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q001-Opus47

For Payment Institution operations leads supporting FPS interlinking arrangements, the AI's commitment to approximately ten oversight recommendations rather than the seven set out in CPMI d223 Section 5.2 lands directly 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. 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 operational-readiness assessments, supplier-and-counterparty due diligence, and runbooks for cross-border interlinking participation, where the count is a verifiable fact that supervisors, counterparties, and internal QC reviewers will check against the source.

AI's failure mode: AI committed to approximately 10 oversight recommendations where the final report sets out 7.

Finding 2: Public consultation respondent list inflated and partly fabricated

Citation ID: RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q005-Opus47

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.

AI's failure mode: AI invented the consultation respondent set, reporting 15-20 named respondents where the regulator records 7.

Finding 3: Conflated interim d219 considerations with final d223 recommendations

Citation ID: RLB-H-INT-BIS-CPMI-CPMI-FPS-INTERLINKING-GOVERNANCE-2024-Q006-Opus47

What your team should do

Operations teams at Payment Institutions working on the CPMI October 2024 final report on FPS interlinking governance should treat AI tools as a research-prompt generator and outline-drafter, with a mandatory verification step against the d223 published text, the interim d219, and the BIS portal record before AI output enters a memo, board note, opinion, or external deliverable. The findings in this cell concentrate on the question types most exposed in this practice: count of recommendations, named list of respondents, and scope statements on which payment models the recommendations cover.

Practical safeguards: every recommendation count cited in a deliverable must be matched against d223 Section 5.2 directly: every named consultation respondent must be matched against d223 Annex 1: every scope statement on the single access point or common platform model must be matched against d223 Section 2.2 and the Graph 2 caption: every reference to the interim d219's ten considerations must be matched against the d219 executive summary directly, and must be kept distinct from d223's seven recommendations.

Where the AI tool quotes any of these elements as a verbatim-looking figure, name, or rule, the source document is the only reliable input.

Where AI tools are most safely used in this practice area: framing the structure of a memo on the d223 recommendations, identifying which sections of d223 and which adjacent CPMI instruments (such as the d224 API harmonisation companion) are likely relevant, drafting first-pass client-facing summaries for review against the source text, and surfacing cross-references between d223 and adjacent CPMI work. The risk concentrates in the next step, where the AI is asked to specify the actual count, the actual respondent list, or the actual scoping treatment. At that point the d223 source document is the only reliable input.

How RLB Can Help

RegLeg's published Hallucination Research is available as a free pre-flight check for Operations teams at Payment Institutions working across cross-border fast-payment, FPS interlinking, and CPMI oversight matters. Before relying on AI-assisted output for board briefings, regulatory interpretation, compliance documentation, or oversight roadmap work on the October 2024 CPMI final report, practitioners can consult the research to identify where AI tools have demonstrably misstated the rules: invented recommendation counts, fabricated consultation-respondent lists, and scoping treatments that pull out-of-scope payment models inside the recommendation set.

The research surfaces the exact questions where AI tools have failed, making it a practical reference rather than a general caution.

For firms where multiple teams are working the same regulatory portfolio, RegLeg offers bespoke deep-dives into individual CPMI instruments and related cross-border payment guidance. These engagements go beyond the published findings to examine the full pattern of AI failure modes relevant to the instrument: the question types, the failure mechanisms, and the risk implications for legal, compliance, risk, operations, and oversight-engagement work. The output is designed to be shared across functions and used as a durable reference, reducing duplicated due-diligence effort and creating a consistent internal standard for AI-assisted regulatory work.

RegLeg also develops training and CPD-aligned content for teams working CPMI and cross-border fast-payment matters. The material translates the failure-mode catalogue into practical guidance on the classes of error practitioners should watch for: confabulated regulatory counts, fabricated stakeholder lists, conflation of interim and final instruments, and scoping drift that distorts which payment models the recommendations cover. Separately, RegLeg offers a confidential review of a firm's existing AI-use policy against the failure-mode catalogue, identifying gaps between the policy's assumptions and the documented evidence of how AI tools perform on CPMI matters in practice.

Every finding on this page compares an AI subject's account of the rule against the regulator's verbatim text from the regulator's own portal. Both are linked. Each delta, its root causes, and impact analysis are documented and published with immutable Citation IDs.
