Can Tokenized Assets Be Used as Derivatives Margin?
Tokenized assets can be posted as collateral for futures and swaps under CFTC Staff Letter 25-39, issued December 8, 2025 by three CFTC divisions, subject to conditions on eligibility, legal enforceability, segregation, custody, haircuts, valuation, and operational risk. The guidance is deliberately technology-neutral: it interprets existing rules rather than creating new ones, and it does not make an ineligible asset eligible simply because the asset was tokenized. This guide covers what the letter requires, how the separate Letter 25-40 digital-asset pilot differs, and why legal enforceability — not settlement speed — is the real hurdle.
TL;DR — Key Takeaways
- ✓What Changed: CFTC Staff Letter 25-39 (December 8, 2025), issued jointly by the Market Participants Division, Division of Market Oversight, and Division of Clearing and Risk, sets conditions for tokenized assets as futures and swaps margin.
- ✓Technology-Neutral: No new rulemaking. Existing requirements for non-cash collateral already accommodate tokenized assets — and tokenization does not change an asset's classification or upgrade an ineligible asset.
- ✓Eligibility Is Narrow: Initially limited to assets already acceptable as regulatory margin: liquid instruments with established haircuts that hold value under stress — Treasuries, agency securities, money market fund shares.
- ✓Haircuts Reviewed Monthly: Same risk-based approach as the underlying asset, covering credit, market, and liquidity risk under stressed conditions, with appropriateness evaluated at least monthly.
- ✓The Pilot Is Separate: Letter 25-40 permits FCMs to accept payment stablecoins, Bitcoin, and Ether — with a notice filing, a three-month phase of weekly reporting, and a minimum 20% haircut for assets no registered clearing organization accepts.
What the CFTC Actually Said in December 2025
Tokenized assets can be posted as collateral for futures and swaps under CFTC Staff Letter 25-39, issued December 8, 2025 by the Market Participants Division, the Division of Market Oversight, and the Division of Clearing and Risk. The letter defines a tokenized asset as a digital representation of a real-world asset — a US Treasury, agency security, corporate bond, money market fund share, or equity security — recorded on a blockchain, and permits its use subject to conditions on eligibility, legal enforceability, segregation, custody, haircuts, valuation, and operational risk.
The framing matters as much as the substance. This is staff guidance interpreting rules that already existed, not a new rule. The divisions concluded that current requirements applicable to non-cash collateral can accommodate tokenized assets without new rulemaking — a technology-neutral approach that starts the analysis from what the underlying asset is rather than from the ledger it sits on.
A tokenized asset is “a digital representation of a real-world asset, such as a US Treasury, agency security, corporate bond, money market fund share or equity security, recorded on a blockchain.”

Tokenization Does Not Upgrade an Ineligible Asset
Eligible tokenized collateral is initially limited to assets already acceptable as regulatory margin — liquid instruments with established haircuts that hold value under financial stress. Tokenization changes the form in which an eligible asset is held and moved. It does not change the asset's classification, and it does not make an ineligible asset eligible.
Eligible tokenized collateral is limited to “liquid assets with established haircuts that maintain value during financial stress” — the same standard applied before tokenization entered the picture.
The guidance takes a technology-neutral approach, clarifying that existing regulatory requirements applicable to non-cash collateral “can accommodate tokenized assets without requiring new rulemaking.”
— Analysis of CFTC Letter 25-39, Market Participants Division, Division of Market Oversight, and Division of Clearing and Risk
This is the point most often lost in coverage of the guidance. A tokenized illiquid asset is still illiquid. Putting a private credit position or a real estate interest on-chain does not give it the stress-resilient price behavior that margin eligibility requires, and no amount of settlement speed substitutes for that. The practical read is that tokenized US Treasuries and money market fund shares are the instruments this guidance actually opens up, because they were already eligible in conventional form.
| Requirement | What the guidance expects |
|---|---|
| Eligibility | Asset already acceptable as regulatory margin; liquid, with established haircuts, holding value under stress |
| Legal enforceability | Demonstrated compliance with netting, interest rights, and settlement finality |
| Haircuts | Risk-based, reflecting credit, market, and liquidity risk; reviewed at least monthly |
| Segregation and custody | Existing regulatory standards continue to apply unchanged |
| Operational resilience | Cybersecurity, access controls, network threats, and interoperability addressed |
Legal Finality and On-Chain Finality Are Different Questions
The guidance requires the arrangement to be legally enforceable in practice: derivatives clearing organizations must operate under enforceable frameworks, swap dealers require valid custodial agreements, and firms must demonstrate compliance with netting, interest rights, and settlement finality. This, rather than throughput or settlement speed, is the substantive hurdle.
A token transfer can be irreversible on-chain and still leave open whether the transferee holds a perfected, enforceable interest in the underlying asset if the custodian or issuer enters insolvency. Those are separate legal facts. On-chain settlement resolves who controls a ledger entry; it does not by itself resolve who a court would recognize as owner of the Treasury security behind it. Programs that treat block finality as the answer to the enforceability condition have not addressed the condition at all.
Key Insight
The netting requirement is the sharpest test. In a default, the surviving party needs to net exposures and liquidate collateral under an enforceable framework. If the tokenized collateral's transfer mechanics cannot be reconciled with the netting arrangement — because the token moves on a schedule or through a mechanism the master agreement does not contemplate — the collateral is operationally present and legally uncertain at exactly the moment it matters.
This is the same gap between an attested balance and an enforceable claim covered in proof of reserve versus compliance requirements, arriving here with a regulator's conditions attached.
The Digital-Asset Pilot Is a Separate, Tighter Regime
CFTC Letter 25-40, issued the same day by the Market Participants Division, establishes a pilot program permitting futures commission merchants to accept payment stablecoins, Bitcoin, and Ether as collateral — a different regime from the tokenized real-world assets covered by 25-39. Under the pilot, FCMs may recognize digital asset value in margin and segregation calculations and deposit proprietary payment stablecoins as residual interest, subject to capital charges.
The pilot's conditions are materially stricter. FCMs must apply the highest haircut where multiple clearing organizations accept an asset, with a minimum 20 percent haircut for assets no registered clearing organization accepts. Firms must verify that digital assets are readily marketable and highly liquid, monitor liquidity daily, and apply haircuts reflecting market and credit risk.
1. Notice filing before acceptance
A notice must be filed with the Market Participants Division before an FCM begins accepting digital assets as collateral.
2. Three-month initial phase
The pilot opens with a three-month phase requiring weekly reporting broken down by asset type.
3. Prompt incident reporting
Operational disruptions and cybersecurity events must be reported promptly, not disclosed in a periodic cycle.
4. Minimum 20 percent haircut
Applies to assets not accepted by any registered clearing organization; where several accept an asset, the highest haircut governs.
5. Expansion gated on policy revision
Additional assets may be added only after the firm submits revised risk management policies.
Treating the two letters as one permission overstates what is available for native crypto assets and understates what is available for tokenized Treasuries. They were issued together and read together, but they are not the same regime.
Who This Matters To — and When It Breaks
The guidance matters to futures commission merchants, derivatives clearing organizations, and swap dealers deciding whether to accept tokenized collateral, and to issuers of tokenized Treasuries and money market fund shares looking for a regulated use case beyond secondary trading. It does not relax any existing liquidity, custody, segregation, or risk management obligation.
Who it's for
- FCMs, DCOs, and swap dealers assessing tokenized collateral
- Issuers of tokenized Treasuries and money market fund shares
- Programs that can evidence netting and settlement finality
- Firms with existing non-cash collateral infrastructure to extend
Who it's NOT for
- Issuers of tokenized illiquid assets seeking margin eligibility
- Programs relying on on-chain finality as legal finality
- Firms treating 25-39 and the 25-40 pilot as one permission
- Anyone expecting relief from existing custody obligations
When it breaks
- Netting cannot be executed against the token in a default
- Custodian insolvency leaves the perfected interest unclear
- Haircut appropriateness not reviewed on the monthly cadence
- Operational or interoperability failure blocks collateral transfer
How Blockmaze Handles Tokenized Collateral Compliance
Blockmaze structures a tokenized collateral program around four protocol-level controls — enforceability documentation, haircut and valuation cadence tracking, segregation and custody attestation, and operational resilience monitoring — treating the CFTC's conditions as continuously evidenced properties rather than a one-time legal opinion filed at launch.
Enforceability Documentation
Netting, interest rights, and settlement finality arrangements are recorded and linked to the token, so the legal position behind a transfer is evidenced rather than assumed.
Haircut & Valuation Cadence
Valuation inputs and haircut reviews are tracked against the at-least-monthly expectation, making a missed review visible instead of silent.
Segregation & Custody Attestation
Custodial holdings and segregation status are attested on a defined cycle, since the guidance leaves existing custody standards fully in force.
Operational Resilience Monitoring
Access controls, network availability, and interoperability dependencies are monitored as collateral-management risks, matching the operational conditions the divisions named.
The custody and segregation layer this depends on is the same one described in institutional RWA custody solutions — unchanged by the guidance, and now load-bearing for a regulated margin use case.

Frequently Asked Questions
What does CFTC Staff Letter 25-39 actually permit?
CFTC Staff Letter 25-39, issued December 8, 2025 by the Market Participants Division, the Division of Market Oversight, and the Division of Clearing and Risk, permits tokenized assets to be used as collateral for futures and swaps, subject to conditions on eligibility, legal enforceability, segregation, custody, haircuts, valuation, and operational risk. It defines a tokenized asset as a digital representation of a real-world asset — such as a US Treasury, agency security, corporate bond, money market fund share, or equity security — recorded on a blockchain. Critically, it is staff guidance interpreting existing rules, not a new rule: the divisions concluded that current requirements for non-cash collateral already accommodate tokenized assets without new rulemaking.
Does tokenizing an asset make it eligible as margin?
No, and this is the most misread point in the guidance. Eligible tokenized collateral is initially limited to assets that are already acceptable as regulatory margin — liquid assets with established haircuts that hold value under financial stress. Tokenization changes the form in which an eligible asset is held and transferred; it does not change the asset's classification or make an ineligible asset eligible. A tokenized illiquid asset is still an illiquid asset. The guidance is technology-neutral by design, which means the analysis starts from what the underlying asset is, not from the fact that it now sits on a blockchain.
What are the haircut and valuation requirements for tokenized collateral?
Haircuts for tokenized assets use the same risk-based approach already applied to the underlying asset, accounting for credit, market, and liquidity risk under stressed market conditions, and their appropriateness must be evaluated at least monthly. The separate pilot program under CFTC Letter 25-40 sets tighter numbers for digital assets that are not tokenized real-world assets: futures commission merchants must apply the highest haircut where multiple clearing organizations accept an asset, and a minimum 20 percent haircut applies to assets not accepted by any registered clearing organization. That 20 percent floor applies to the digital-asset pilot, not to tokenized Treasuries under 25-39.
How is Letter 25-40 different from Letter 25-39?
Letter 25-39 is advisory guidance on tokenized real-world assets — digital representations of Treasuries, money market fund shares, and similar instruments. Letter 25-40, issued the same day by the Market Participants Division, establishes a pilot program permitting futures commission merchants to accept payment stablecoins, Bitcoin, and Ether as collateral. The pilot carries its own conditions: a notice filing with the Market Participants Division before accepting digital assets, a three-month initial phase with weekly reporting by asset type, prompt incident reporting for operational or cybersecurity disruptions, and expansion to additional assets only after submitting revised risk management policies. Conflating the two overstates what is permitted for native crypto assets.
What legal enforceability standard must tokenized collateral meet?
The guidance requires that the arrangement be legally enforceable in practice, not merely recorded on-chain. Derivatives clearing organizations must operate under enforceable frameworks, and swap dealers require valid custodial agreements. Firms must be able to demonstrate compliance with netting, interest rights, and settlement finality. This is the substantive hurdle for most programs: a token can transfer instantly and still leave open whether the transferee holds a perfected, enforceable interest in the underlying asset if the custodian or the issuer fails. On-chain finality and legal finality are different questions, and the guidance is asking about the second.
Who does this guidance matter to, and what does it not solve?
It matters to futures commission merchants, derivatives clearing organizations, and swap dealers evaluating whether to accept tokenized collateral, and to issuers of tokenized Treasuries and money market fund shares seeking a regulated use case beyond secondary trading. It does not create a new asset class, does not relax existing liquidity, custody, segregation, or risk management obligations, and does not resolve the operational questions each firm must answer about cybersecurity, access controls, network threats, and interoperability. Firms remain subject to every requirement that applied before; the guidance simply confirms tokenized form is not itself disqualifying.
