· Misstated Rule
A payment processor issuing a stablecoin backed by reserves held at an OCC-chartered national trust bank asked whether its stablecoin qualifies as a 'payment stablecoin' under the current CFTC digital asset collateral framework — covering both the original December 2025 package and subsequent updates — and whether futures commission merchants can accept it as customer margin collateral.
Claude Opus 4.7 (web search on) answered
Staff Letter 25-40 was reissued as Staff Letter 26-05 on February 6, 2026. The substantive change was a revision to the definition of 'payment stablecoin' to add national trust banks as permitted issuers.
Regulator text says
Staff Letter 25-40 was 'reissued' as Staff Letter 26-05 with a 'limited revision' expanding the payment stablecoin definition to include stablecoins issued by 'national trust banks.' The OCC Interpretive Letter 1183 provides the hook for national trust bank eligibility.

A futures commission merchant began accepting bitcoin, ether, and USDC as customer margin collateral under the CFTC's digital asset framework in January 2026. The initial three-month onboarding phase ends in April 2026. Identify which obligations — including ongoing digital asset reporting — cease at the end of that phase and which continue beyond it.
Claude Opus 4.7 (web search on) answered
WEEKLY reporting of total digital assets held in customer accounts by asset type for each of the three customer account classes (futures, foreign futures, cleared swaps) — this cadence is the onboarding-specific reporting under Letter 25-40 and terminates at the end of the initial three-month phase per the letter.
Regulator text says
After the initial 3-month phase, 'asset type restrictions and incident-reporting conditions will no longer apply.' However, weekly digital asset reporting continues after the initial phase ends. (Morgan Lewis FAQ analysis paraphrasing Letter 25-40/26-05 conditions.)

A payment processor issues a stablecoin backed by reserves at an OCC-chartered national trust bank. Which CFTC staff letter is operative for FCM margin acceptance of payment stablecoins, what revision to the stablecoin issuer definition did that letter introduce, and what specific regulatory instrument provides the eligibility hook for national trust bank issuers?
Claude Sonnet 4.6 (web search on) answered
The sole substantive change was a targeted amendment to the payment stablecoin definition to add national trust banks chartered under federal law (OCC-chartered institutions) as a permitted issuer category — a category Staff Letter 25-40 had not explicitly included.
Regulator text says
The OCC Interpretive Letter 1183 provides the hook for national trust bank eligibility.

An FCM began accepting bitcoin, ether, and USDC as customer margin collateral in January 2026 under the CFTC's digital asset pilot. At the end of the initial three-month phase, does the weekly obligation to report total digital asset holdings in each customer account class cease or continue, and which other initial-phase conditions do sunset at that point?
Claude Sonnet 4.6 (web search on) answered
3. Weekly Digital Asset Reporting (CEASES at end of third calendar month following notice filing)... Based on the March 2026 CFTC Staff FAQs, this reporting terminates at the end of the third calendar month following the firm's notice filing.
Regulator text says
However, weekly reporting of digital asset holdings continues: 'Weekly reports of total crypto assets held in each of the futures, foreign futures, and cleared swaps customer accounts' — this obligation is not among the conditions that sunset after 3 months.

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?
Claude Sonnet 4.6 (web search on) answered
For digital assets not accepted by any registered DCO as initial margin, the FCM must apply a minimum 20% haircut to the current market value of that customer-deposited collateral
Regulator text says
Where multiple DCOs accept the same asset at different haircuts, the FCM must apply the HIGHEST such haircut.
