For FCM and clearing-member risk and compliance officers relying on a conditional regulatory relief (a no-action, exemptive, or comfort letter) to accept an asset as collateral. The relief is conditional and staff-level, not a rule: it can be narrowed, reissued, or withdrawn, and when it moves, the question that matters is not whether the relief still applies today but what you are left holding if it does not. art-514, the conditional-relief collateral receipt, answers that directly: per-condition evidence that the relief's terms held, a check on whether you are relying on a version that has since moved, and the capital and eligibility figure if the relief were withdrawn.
CFTC Staff Letter 25-40 (8 Dec 2025) permitted FCMs to accept certain non-security digital assets, namely payment stablecoins, Bitcoin and Ether, as margin collateral, subject to conditions on valuation, haircuts, regulatory reporting and risk management. It was reissued as Letter 26-05 on 6 Feb 2026, updating the payment-stablecoin definition so a national trust bank could qualify as a permitted issuer, and clarified further by FAQs on 20 Mar 2026. Two revisions inside three months is the ordinary lifecycle of staff-level relief, not an edge case. The question a risk or compliance officer actually needs answered is not "does the relief cover this asset today," which a policy memo can state once and leave stale, but "if this relief were narrowed or withdrawn tomorrow, what capital charge and eligibility status would this position revert to." That is a standing exposure, not a one-time eligibility opinion, and it needs to be re-checked every time the position is held, not only when it was first booked.
Conditional relief of this kind is not unique to derivatives margin or to the CFTC. An SEC no-action letter, an OCC interpretive letter, an FCA temporary permission, or an MAS exemption can each condition the acceptance or treatment of an asset on a set of facts holding true (an issuer's regulatory status, a valuation methodology, a reporting cadence), with the relief itself remaining revocable by the same staff-level process that granted it. art-514 is built to that general shape: the caller declares the regime label, the version of the relief they are relying on, and the specific conditions attached to it, and the node checks the declared evidence against the declared conditions. Nothing is hardcoded to any one regulator's letter numbers or thresholds.
art-514 never marks a condition PASS on absent evidence: a blank or unrecognized evidence status is reported as UNDECIDABLE, distinct from a declared FAIL. It compares the relief version the caller says they relied on against the version their condition set was evidenced against, so a reissue that has already happened but has not yet been reflected in the caller's records surfaces as CRC_RELIEF_VERSION_STALE rather than passing silently. It does not rebuild reserve checking or haircut and eligibility logic; those are reused, unedited, from the nodes composed ahead of it in the chain below. It renders no eligibility opinion: it reports whether the caller's own declared conditions were met against the caller's own declared evidence, nothing more.
art-514 consumes the reserve, eligibility and haircut steps' outputs as inputs and edits none of them. See the conditional-relief-collateral chain page for the full composed run.
The revocation-exposure figure is the answer to one question a CFO or treasurer actually asks: if this relief disappeared tomorrow, what happens to the capital already committed against this position, and does the asset stay eligible as collateral at all? art-514 computes it directly from the caller's own numbers, the capital charge that applies today under the relief against the charge that would apply if the relief were withdrawn, and reports the delta between the two, plus whether the asset would lose collateral eligibility entirely. A payment stablecoin currently charged at 2% under the relief but reverting to a 20% commodities-style charge without it carries a materially different capital cost than the figure booked today; the receipt puts that delta in front of the reader as a single number rather than leaving it implicit in a policy memo nobody re-reads after the position is booked. CRC_REVOCATION_EXPOSURE_MATERIAL fires when that delta is positive or when the asset would lose eligibility outright, so the exposure is visible without requiring the reader to do the arithmetic themselves.
