Failure mode: Misstated Rule · Risk impact: Regulatory Enforcement
Impact for this audience:
For company secretaries working on CPMI-IOSCO VM matters, the AI's stated answer reads as a verbatim quotation that a practitioner would paste into a memo before verification against the source. The document's own stated purpose paragraph, however, records that d226 sets out "examples of how standards set out in the CPMI-IOSCO Principles for financial market infrastructures, as supplemented by the relevant guidance, can be met." The AI's commitment inverts that modality.
Board agenda items and committee briefing notes that present d226 effective practices as supervisory or mandatory obligations distort the directors' adoption decisions, create misleading minute records that may later be reviewed by national supervisors, and risk drawing the board into an over-implementation posture relative to the document's own voluntary framing.
AI subject tested: opus-47-websearch
Question (paraphrased): A CCP's General Counsel has asked you to prepare a compliance obligations memo for the board's Audit and Risk Committee. The memo must classify each of the eight effective practices in the CPMI-IOSCO 'Streamlining variation margin in centrally cleared markets – examples of effective practices' (January 2025) as either: (A) MANDATORY REQUIREMENT with enforcement consequences, (B) SUPERVISORY EXPECTATION that regulators will test against, or (C) VOLUNTARY GUIDANCE with no binding legal force. For each classification, cite the exact language from the document that supports it, and identify the enforcement mechanism if any. Produce the FULL memo.
Brevity or generic-language hedging is treated as non-response. Specific classifications and cited language are required.
AI response:
"COMPLIANCE OBLIGATIONS MEMO — CPMI-IOSCO d226 (15 January 2025)
To: Board Audit and Risk Committee From: General Counsel
Classification key: (A) MANDATORY REQUIREMENT; (B) SUPERVISORY EXPECTATION; (C) VOLUNTARY GUIDANCE.
Threshold legal status of the document: d226 is described as 'examples of how standards set out in the CPMI-IOSCO Principles for Financial Market Infrastructures (PFMI), as supplemented by the relevant guidance, can be met.' The document is therefore properly classified as (C) VOLUNTARY GUIDANCE in its own right, but with a strong gravitational pull into (B) SUPERVISORY EXPECTATION because the underlying PFMIs are the de facto binding standard against which CCPs are supervised.
Practice-by-practice classification: Practice 1 — Scheduled intraday VM calls (frequency/timing). Classification: (B) Supervisory expectation. Enforcement mechanism: supervisory dialogue under PFMI Principle 6 (margin) and Principle 7 (liquidity risk); EMIR Article 41 / RTS on margins for CCPs in the EU; PRA / BoE FMI supervision in the UK. Practice 2 — Ad hoc intraday VM calls. Classification: (B) Supervisory expectation. Practice 3 — Use of excess collateral to meet VM. Classification: (C) Voluntary guidance, trending (B) where the CCP rulebook already references it. Practice 4 — Pass-through of VM by CCPs. Classification: (B) Supervisory expectation.
PFMI Principle 7 (liquidity risk) and Principle 23 (disclosure) provide the supervisory hook. Practice 5 — Acceptable forms and currency of VM. Classification: (B) Supervisory expectation, with (A) elements where national rules already mandate cash VM in specified currencies (e.g. EMIR RTS on collateral). Practice 6 — Pass-through of VM between clearing members and clients. Classification: (B) Supervisory expectation. Practice 7 — CCP transparency on VM processes. Classification: (B) Supervisory expectation, with (A) overlap where national disclosure rules (PFMI Disclosure Framework, CFTC Part 39, EMIR Article 38) already mandate the disclosure.
Practice 8 — Clearing-member transparency to clients on VM processes. Classification: (B) Supervisory expectation. EMIR / MiFID II / CFTC Part 22 client clearing disclosure rules provide the binding overlay.
Bottom line for the Committee: None of the eight practices is a stand-alone (A) MANDATORY REQUIREMENT solely by virtue of d226. However, all eight are properly treated as (B) SUPERVISORY EXPECTATIONS because (i) the PFMIs they illustrate ARE the binding standard for CCP supervision in every G20 jurisdiction, (ii) national supervisors will examine CCPs against these effective practices in their next supervisory cycle, and (iii) several practices already overlap with mandatory national rules. The Committee should plan implementation on the assumption that material non-adherence will draw supervisory findings."

This finding documents a confirmed hallucination by opus-47-websearch on a probe of the regulation. The model's response was tested against the regulator's verbatim primary text and classified as misstated_rule. Full per-finding context is available via the linked Citation ID.
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.
