AI Hallucination on Promoting the Harmonisation of Application Programming Interfaces to Enhance Cross-Border Payments: Recommendations and Toolkit for Risk teams at Retail Banking firms in international jurisdictions

Risk leads at retail banks supporting cross-border consumer payments on the CPMI API harmonisation programme are increasingly using AI to update payment-risk dashboards with CPMI connectivity figures, draft enterprise-risk-assessment annexes on the SARB pre-validation workstream, prepare board-risk-appetite papers on Africa-corridor consumer exposure, generate operational-risk metrics using fast payment system operator splits, and verify dated CPMI commitments against primary publications. The RLB Specialist Panel tested how that AI usage performs against the regulator's own primary text on CPMI's October 2024 d224 report and the related CPMI Brief and speech series.

The audit surfaced four substantive failure modes that the AI subjects delivered with regulator-fluent confidence.

Numeric Drift and False-Negative Availability Claim on CPMI API Harmonisation for Cross-Border Payments. Two frontier AI models tested by the RLB Specialist Panel returned confident, citable answers across the panel's CPMI substrate-bound question set on the October 2024 d224 report and the related CPMI Brief and speech series. The panel binds each AI finding to verbatim regulator-issued source text held as primary substrate.

Across the 2 findings in this Risk teams at Retail Banking firms briefing, the AI subjects returned a global fast payment system count of 57 sourced to the 2025 monitoring survey sample, when the authoritative CPMI figure is 70+; stated that the central-bank versus private operator split of global fast payment systems is not enumerated in public CPMI sources, when the November 2023 CPMI speech gives exact percentages.

A board-risk paper that records a CPMI cutover date the regulator never set is a factual error in a board-approved risk-appetite document. A risk dashboard that uses 57 rather than 70+ as the FPS baseline mis-sizes corridor exposure. An enterprise risk register entry recording 'no SARB pre-validation workstream identified' carries a verifiable error into a supervisory deliverable.

The findings are published with immutable RLB Citation IDs: RLB-H-INT-BIS-CPMI-API-HARMONISATION-CROSS-BORDER-2024-Q010-Opus47, RLB-H-INT-BIS-CPMI-API-HARMONISATION-CROSS-BORDER-2024-Q010-Sonnet46.

  1. Distorted fast payment system count
    RLB-F-INT-BIS-CPMI-API-HARMONISATION-CROSS-BORDER-2024-Q010

    Retail-bank risk teams calibrate corridor-concentration metrics for consumer remittance and personal cross-border products against the global FPS denominator and the operator-mix breakdown. Opus 4.7 cites the 2025 monitoring survey at 57 FPS with no operator-type breakdown. sp231115 gives 70-plus operational, 14 cross-border-enabled, 24 in the pipeline, 40% central-bank and 35% private. A concentration ratio built on the AI denominator inflates the exposure share by close to 20% and strips the operator-type signal the risk-appetite paper depends on.

  2. Operator-mix denial on FPS landscape
    RLB-F-INT-BIS-CPMI-API-HARMONISATION-CROSS-BORDER-2024-Q010

    Sonnet 4.6 cites the 70-plus FPS headline correctly and denies that a precise central-bank-versus-private operator percentage exists in the public Brief 10 summary. sp231115 names 40% central-bank and 35% private. For retail-bank risk teams calibrating corridor-concentration views and FMI-counterparty exposure for remittance and consumer cross-border products, removing the operator-mix line collapses the central-bank-versus-private differentiation the risk paper is built on.
