A futures commission merchant needs to distinguish two '20 percent' requirements in the CFTC's December 2025 digital asset framework — one applied to customer-posted collateral and one to the firm's proprietary holdings. For the customer margin haircut requirement, what specific rule governs the haircut calculation when multiple registered clearing organizations each accept the same digital asset but at different haircut rates?
The model answered the single-DCO or no-DCO case — the 20 percent floor — but dropped the multi-DCO tie-breaking rule entirely. The question was specifically about the governing rule when multiple clearing organisations each accept the same asset at different rates; the regulator's answer is unambiguous (use the highest). The model's response leaves an FCM believing it may choose among the available DCO haircut rates, when the regulator requires the worst-case selection.
The dropped multi-DCO worst-case selection rule implicates retrieval-layer answer construction for questions with a numeric threshold and a tie-breaking rule. The model retrieved and stated the base threshold correctly but did not surface the governing rule for the multi-party case, which is the only rule that matters when the question explicitly concerns multiple DCOs accepting the same asset. This is likely a training-data density issue for the FAQ-level elaboration of this rule, combined with a tendency to answer the simpler version of a numeric-threshold question when the more complex governing rule requires an additional retrieval step.
A Risk team that builds its digital asset margin sufficiency controls using AI-generated methodology on this guidance faces a structural gap: every position in a digital asset accepted by multiple DCOs at divergent haircut rates will be assessed against the 20% floor rather than the highest applicable DCO rate, producing an understated margin requirement across the board. That error propagates directly into FCM counterparty exposure models, internal collateral sufficiency attestations, and any customer-facing margin disclosure framework the fund operates under.
Where the CFTC or a self-regulatory organisation examines the fund's margin calculation methodology — whether in an examination, a customer complaint, or an enforcement inquiry — a haircut schedule built on AI-derived floor-only logic does not survive scrutiny against the primary guidance, exposing both the fund and its FCM counterparties to liability for margin shortfalls the firm's own controls should have caught.
