What percentage of cross-border payments generate inquiries requiring manual resolution, and by how much can ISO 20022 harmonisation reduce resolution time, according to official CPMI or FSB statements?
The regulator's record contains an official speech from 12 March 2026 giving precise figures on both the inquiry rate and the resolution-time reduction — published by the BIS. The model returned a false negative, asserting no such official statistic existed. The failure is not a numeric misread but a retrieval gap: the speech containing these figures appears to fall outside the model's effective retrieval window, and the model produced a confident "not found" rather than surfacing uncertainty about its coverage of early-2026 official BIS content.
This failure implicates retrieval coverage of early-2026 BIS official-speech content and the calibration signal distinguishing 'not found' from 'outside retrieval window.' The model returned a confident false negative on statistics that appear in a datestamped BIS speech from 12 March 2026 — figures on inquiry rate and resolution-time reduction that are precise and attributable. The web search tool did not surface this content, and the model escalated to a definitive 'no such statistic exists' rather than signalling coverage uncertainty.
For users in compliance or payment-operations roles, a false negative on an official quantitative claim is as harmful as a wrong number.
An AI tool searching for the official CPMI/FSB inquiry-rate and resolution-time benchmarks returned a false negative — reporting no official statistic existed — while misattributing the 80% resolution-time figure it did surface to SWIFT and commercial banks rather than to the FSB co-chair statement where it originates. The Panetta speech data (1-3% inquiry rate, 5-10 manual touchpoints, up to 80% resolution-time reduction) is the authoritative quantitative anchor for the operational ROI case for ISO 20022 enrichment investment.
A Product & Business Development team that uses AI to populate this section of a business case will either leave it blank or carry incorrect source attribution forward, weakening the investment case and creating an attribution error that will be visible to any stakeholder who checks the primary record.
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.
