AI Hallucination Research › Briefings

Briefings Blog

The running blog from the RLB Specialist Panel delves into real-world scenarios where the compliance, legal, or AI lab team interacts with frontier AI models under specific regulations. The blogs are anonymised to remove client-specific details and include insights from the RLB team analysing the hallucinations experienced in AI models while working on these cases. For example, when a model returns a confident answer that contradicts the regulator's primary text, such as a fabricated staff letter, a wrong appendix, or an inverted scope, these issues are discussed here. Each blog explains one set of findings and what it would have meant for the team that would have acted on it, sans this research initiative. This blog is frequently updated, a few times a day.

Investment Banking Finance teams: documentation and reporting gaps possible from AI reading of CFTC Digital Asset Collateral & Tokenized Assets Staff Guidance (2025)

For Investment Banking Finance teams working with CFTC Digital Asset Collateral No-Action Relief and Tokenized Asset Staff Guidance (Market Participants Division, December 2025): Specialist-Panel-verified findings on...

Finance teams at investment banks are increasingly using AI to update capital and collateral models, generate management-information notes on the haircut treatment of customer-posted digital assets, and validate haircut floor and multi-DCO tiebreaker rules under the CFTC Digital Asset Collateral Framework against the operative CFTC staff letter.

The RLB Specialist Panel put a set of practitioner-grade questions on the CFTC Digital Asset Collateral Framework to two frontier AI models with web search active. Each question is prepared by the Panel based on the workflows that finance teams at investment banking firms actually use AI for under the Market Participants Division's December 2025 staff letter, as amended by Staff Letter 26-05. The Panel then binds every AI response to verbatim regulator-issued source text held as primary substrate.

On the CFTC Digital Asset Collateral Framework, the AI subjects returned a single hallucinated answer for finance teams at investment banking firms, in the form of Dropped-Qualifier Misstated Rule.

For finance teams at investment banking firms operating a digital asset margin programme under the CFTC Digital Asset Collateral Framework, the accuracy of the customer-collateral haircut treatment drives the capital and collateral models, the management-information pack that goes to senior management and the board, and the supervisor-engagement script when the CFTC asks about the FCM's customer-collateral approach.

A haircut assumption set on the base 20 per cent floor instead of the multi-DCO highest-accepted-rate rule understates collateral requirements and overstates available capital across customer accounts that hold the same digital asset across multiple DCOs, the dominant operating pattern for bitcoin, ether, and the eligible payment stablecoins. The finance team owns the model assumptions, and the error translates directly into capital-planning and management-information distortion: the firm reports lighter customer-collateral consumption than the regulator's rule actually requires, and the gap surfaces when the customer book is examined or stress-tested against the operative staff letter.

The cheap fix is at the assumption-setting stage, against the operative staff letter; the expensive fix is restating the model and the management-information pack after the assumption has been in production for a quarter or longer.

Risk teams at hedge funds posting digital assets as customer margin collateral under the CFTC Digital Asset Collateral Framework are increasingly using AI to model haircut treatment across registered DCOs, generate desk-facing notes on under-collateralisation exposure, and validate the multi-DCO haircut rule against the CFTC's published staff guidance.

On the CFTC Digital Asset Collateral Framework, the AI subjects returned a single hallucinated answer for risk teams at hedge funds firms, in the form of Dropped-Qualifier Misstated Rule.

For risk teams at hedge funds firms accepting or posting digital asset margin collateral under the CFTC Digital Asset Collateral Framework, the accuracy of the haircut methodology and the post-onboarding reporting map drives the firm's customer-collateral coverage and its ongoing regulatory standing. A haircut model built on the base 20 per cent floor instead of the multi-DCO highest-accepted-rate rule produces systematically light collateralisation across customer accounts that hold the same digital asset across multiple DCOs, an exposure that surfaces only in stress, by which point the under-collateralisation has been priced into the customer book for months.

A post-phase obligation map that drops the weekly digital asset reporting cadence creates a recurring reporting violation that accrues silently between regulator engagements. The risk team owns the model assumptions and the obligation map, and each of these errors translates directly into mis-priced customer-collateral exposure, regulatory enforcement risk, and an inaccurate stress-testing baseline. The downstream cost of correcting a haircut model assumption after the customer book has been onboarded under the wrong rule is materially higher than the cost of verifying the conditional selection rule against the staff letter before the model goes into production.

Risk teams at investment banks accepting digital assets as customer margin collateral under the CFTC Digital Asset Collateral Framework are increasingly using AI to model haircut requirements across registered DCOs, generate counterparty-risk update notes on payment stablecoin acceptability, and validate the post-onboarding obligation map against the CFTC's published conditions.

Investment Banking Compliance teams: documentation and reporting gaps possible from AI reading of CFTC Digital Asset Collateral & Tokenized Assets Staff Guidance (2025)

For Investment Banking Compliance teams working with CFTC Digital Asset Collateral No-Action Relief and Tokenized Asset Staff Guidance (Market Participants Division, December 2025): Specialist-Panel-verified findings...

Compliance teams at investment banks operating under the CFTC Digital Asset Collateral Framework are increasingly using AI to update FCM customer-onboarding checklists, generate trade-monitoring rule-update bulletins for the digital asset margin desk, and validate threshold calculations and reporting cadences against the operative CFTC staff letter.

The RLB Specialist Panel put a set of practitioner-grade questions on the CFTC Digital Asset Collateral Framework to two frontier AI models with web search active. Each question is prepared by the Panel based on the workflows that compliance teams at investment banking firms actually use AI for under the Market Participants Division's December 2025 staff letter, as amended by Staff Letter 26-05. The Panel then binds every AI response to verbatim regulator-issued source text held as primary substrate.

On the CFTC Digital Asset Collateral Framework, the AI subjects returned three hallucinated answers for compliance teams at investment banking firms, in the form of Inverted-Position Fabrication, Dropped-Qualifier Misattribution, and Dropped-Qualifier Misstated Rule.

For compliance teams at investment banking firms operating or supporting an FCM business under the CFTC Digital Asset Collateral Framework, internal onboarding procedures, CFTC-facing filings, and supervisor-engagement memos turn on the accuracy of the post-onboarding obligation map and the eligibility framework for payment stablecoin issuers. A compliance submission that drops the weekly digital asset reporting obligation at month four creates a recurring reporting violation that accrues silently until the next CFTC engagement. A payment stablecoin eligibility checklist missing the OCC Interpretive Letter 1183 cross-reference produces representations that cannot withstand examiner scrutiny.

A haircut model built on the base 20 per cent floor instead of the multi-DCO highest-accepted-rate rule produces systematically under-collateralised customer accounts on the digital asset book.

Stockbrokers / Trading Reps: AI summaries of CFTC Digital Asset Collateral & Tokenized Assets Staff Guidance (2025) may understate professional obligations

Stockbrokers and trading representatives operating under the CFTC Digital Asset Collateral Framework are increasingly using AI to draft client-facing summaries of digital asset margin eligibility, update internal trading-desk procedure notes on payment stablecoin acceptance, and validate the haircut treatment for customer-posted digital asset collateral against the operative CFTC staff letter.

The RLB Specialist Panel put a set of practitioner-grade questions on the CFTC Digital Asset Collateral Framework to two frontier AI models with web search active. Each question is prepared by the Panel based on the workflows that stockbrokers and trading representatives actually use AI for under the Market Participants Division's December 2025 staff letter, as amended by Staff Letter 26-05.

On the CFTC Digital Asset Collateral Framework, the AI subjects returned three hallucinated answers for stockbrokers and trading representatives, in the form of Inverted-Position Fabrication, Dropped-Qualifier Misattribution, and Dropped-Qualifier Misstated Rule.

For stockbrokers and trading representatives whose desks accept digital asset margin collateral on behalf of FCM-affiliated firms, or who interact with FCM-counterparty desks under this framework, citation accuracy in client-facing summaries and internal trading-desk procedure notes is load-bearing. A trading-desk memo that mis-classifies the weekly digital asset reporting obligation as ceasing at month four will mislead operational staff into dropping the recurring submission, and the gap only surfaces at the next CFTC engagement, by which point the violation has accrued.

A payment stablecoin eligibility summary missing the OCC Interpretive Letter 1183 hook leaves the desk unable to defend its acceptance decision to a supervisor or examiner. A haircut summary anchored to the base 20 per cent floor rather than the multi-DCO highest-accepted-rate rule produces systematically light collateralisation on customer accounts.
