CFTC Staff Clarify Crypto Collateral Rules and Key Expectations

The Commodity Futures Trading Commission’s staff has moved in two steps to clarify how crypto can be used as collateral in U.S. regulated derivatives markets. On February 6, 2026, the CFTC’s Market Participants Division reissued Staff Letter 25-40 as Letter 26-05 to confirm that payment stablecoins issued by national trust banks can qualify under its no-action framework, after broader tokenized-collateral guidance and digital-asset collateral relief were issued on December 8, 2025. The result is a clearer rule set for futures commission merchants, clearinghouses, and swap firms on valuation, custody, segregation, and legal enforceability.

The story is not that the CFTC has rewritten its core collateral regulations. Staff guidance instead says existing rules are largely technology-neutral, while spelling out what firms must do if they want to use tokenized assets or certain non-security digital assets in practice. That distinction matters for compliance teams: the agency is signaling that crypto collateral may fit inside the current derivatives framework, but only with documented controls around liquidity, haircuts, custody, operational resilience, and customer protection.

February 6, 2026 update narrowed one definition but widened access

The most recent clarification came on February 6, 2026, when the CFTC said its Market Participants Division had reissued Staff Letter 25-40 with a “limited revision” to the definition of “payment stablecoin.” The change specifies that a national trust bank may be a permitted issuer for purposes of the no-action position. The CFTC said staff had become aware that stablecoins otherwise meeting the letter’s definition could be issued by a national trust bank, and that excluding them had not been the division’s intent.

That matters because Letter 25-40, first issued on December 8, 2025, gave no-action relief to futures commission merchants that accept certain non-securities digital assets, including payment stablecoins, as customer margin collateral, and in some cases deposit proprietary payment stablecoins as residual interest in segregated customer accounts. The February 2026 revision did not create a new collateral category from scratch; it expanded the list of issuers that can fit within the existing staff framework.

Why December 8, 2025 guidance set the real compliance baseline

The broader compliance framework arrived on December 8, 2025. In a press release announcing a digital assets pilot program for tokenized collateral, the CFTC said staff from the Market Participants Division, Division of Market Oversight, and Division of Clearing and Risk had issued guidance on the use of tokenized assets as collateral in futures and swaps. The agency said its regulations are technology-neutral and that tokenized assets should be analyzed individually under the existing regulatory framework and firms’ own policies and procedures.

The guidance applies to tokenized real-world assets, including U.S. Treasury securities and money market funds, and highlights five recurring control areas: eligible tokenized assets, legal enforceability, segregation and custody, haircuts and valuation, and operational risks. Those are the practical expectations compliance officers and risk managers now have to map into onboarding, collateral schedules, legal opinions, and daily margin operations.

Letter 25-39, the advisory issued the same day, adds detail. It points to existing CFTC and National Futures Association requirements on risk management, system safeguards, legal risk, and custody. It also states that collateral held as margin by futures commission merchants, derivatives clearing organizations, and swap entities must be held by an eligible custodian and remain subject to segregation and control requirements. Firms also must assess liquidity, marketability, and mark-to-market valuation of non-cash assets held as segregated funds.

5 control areas now drive whether crypto collateral is workable

For market participants, the CFTC staff message is less about crypto branding and more about operational proof. First, firms must determine whether the asset is eligible under the applicable framework. Second, they need legal analysis showing the collateral arrangement is enforceable and properly perfected in the relevant jurisdiction. Third, custody and segregation arrangements must satisfy customer-protection rules. Fourth, valuation and haircut methodologies must reflect liquidity and market risk. Fifth, firms must address operational and cyber risks tied to distributed ledger systems.

Those expectations line up with the CFTC’s earlier policy direction. In November 2024, the GMAC recommendation said the agency had “consistently permitted” non-cash assets as collateral for cleared and non-cleared derivatives, subject to conditions meant to mitigate credit, market, and liquidity risks. The recommendation argued that blockchain-based infrastructure could reduce operational challenges without changing the underlying eligibility rules. The December 2025 staff guidance effectively translates that policy logic into a supervisory checklist.

March 2025 withdrawal removed one barrier before staff opened the door

One underappreciated part of the timeline is the March 28, 2025 withdrawal of Staff Advisory 23-07. The Division of Clearing and Risk said it withdrew that advisory to ensure it did not suggest that digital asset derivatives would be treated differently from other products. In regulatory terms, that was an important reset. It reduced the chance that clearing of digital asset products would be viewed through a separate, more restrictive lens before the later collateral guidance arrived.

That sequence helps explain the CFTC staff’s current posture. First came the removal of guidance that could imply exceptional treatment. Then came a public initiative on tokenized collateral and stablecoins in September 2025. After that, staff issued detailed guidance and no-action relief in December 2025, followed by a narrower definitional fix in February 2026. Taken together, the agency’s direction is toward integration of certain digital assets into regulated derivatives plumbing, but through existing risk controls rather than a bespoke crypto rulebook. That is an inference from the chronology and the text of the staff releases.

Frequently Asked Questions

Conclusion

CFTC staff has clarified expectations on using crypto as collateral by building a layered framework rather than issuing a single sweeping rule. The key dates are March 28, 2025, when staff withdrew a digital-asset clearing advisory; December 8, 2025, when staff issued tokenized-collateral guidance and no-action relief; and February 6, 2026, when the agency clarified that national trust bank-issued payment stablecoins can fit within that relief. For U.S. derivatives firms, the message is clear: crypto collateral may be possible, but only if it can satisfy the same core tests that govern any other high-stakes collateral arrangement.
