CFTC Divisions Issue FAQ Guidance on Crypto Assets and Blockchain Technologies in Derivatives Market

April 14, 2026

Maintenance and valuation of margin collateral is the grease that keeps derivatives markets running.  Citing safety and market stability principles, the Commodities Futures Trading Commission (CFTC) has until recently failed to make clear how futures commission merchants (FCM(s)) and derivatives clearing organizations (DCO(s)) could accept crypto-assets as margin collateral to support the positions on their accounts.  The growing popularity of digital assets (including blue chip assets like Bitcoin and Ethereum, as well as payment stablecoins) as treasury assets, however, has led to an upswell of requests to expand the types of assets that may be used as margin collateral for CFTC regulated derivatives contracts.

In response, the CFTC published two prior staff letters — CFTC Staff Letter 25-39 (relating to tokenized collateral) and CFTC Staff Letter 26-05 (providing a no-action position on digital assets accepted as margin collateral), each of which were relied upon by FCMs and DCOs to begin using crypto assets and blockchain technologies for margin collateral purposes.  Coming off the heels of this guidance is a FAQ published by The Market Participants Division (MPD) and the Division of Clearing and Risk (DCR).  Although the FAQ clarifies the application of the two prior letters, it does not create new binding rules or enforceable rights, nor does it necessarily represent the views of the Commission itself; rather, it reflects the views of the two Divisions, and is intended to provide additional clarity to market participants navigating the evolving regulatory landscape for digital assets.

This alert provides an overview of the key takeaways from the FAQ and summarizes the practical impact it may have on market participants, including private funds that invest in derivatives or crypto-assets that are eligible to post as margin collateral.

Key Takeaways from the FAQ

1. FCMs may only accept certain crypto-assets as customer margin. Under CFTC Staff Letter 26-05, an FCM may accept non-security crypto assets — including “payment stablecoins”, BTC, and ETH — as margin collateral deposited in customer futures, foreign futures, or cleared swaps accounts. A stablecoin issued by the FCM itself, however, is not permitted to be used. FCMs may apply the value of permitted non-security crypto-assets, after applicable haircuts, to secure a customer’s debit or deficit account balance.  Here again, CFTC staff is clarifying that these assets are good collateral in regulated markets.

2. DCO are similarly restricted with respect to what crypto-assets can be used as initial collateral. DCOs may accept crypto assets, including “payment stablecoins”, as initial margin for cleared transactions subject to minimal credit, market, and liquidity risks set forth in Commission Regulation 39.13(g)(10).

3. The definitional importance of “payment stablecoins” and the GENIUS ACT. In the FAQ, the term “payment stablecoin” is defined to mean: (i) prior to the effective date of the GENIUS Act, a USD-denominated stablecoin that is issued by a state-regulated money transmitter, state-regulated trust company, or a national trust bank; maintains reserve assets limited to direct or indirect investments in cash, U.S. treasury securities or overnight U.S. Treasury repurchase agreements; and publishes monthly attestations regarding the composition of the reserve assets and whether the fair value of the assets held in reserve is equal to the amount of stablecoins in circulation; and (ii) following the effective date of the GENIUS Act, a stablecoin that meets the requirements contained in the GENIUS Act’s definition of “payment stablecoin” and is issued by a “permitted payment stablecoin issuer” or a “foreign payment stablecoin issuer” that complies with the GENIUS Act’s requirements applicable to such issuers.

This shifting definition may be buried in a footnote, but it is key to keep in mind.  FCMs and DCOs who rely on the FAQ should closely monitor the effective date of the GENIUS Act and assess the extent to which its adoption may alter the menu of “payment stablecoins” that may be accepted as collateral margin on an ongoing basis.  In particular, the definition of “permitted payment stablecoin issuer” under the GENIUS Act may expand the amount of non-bank entities and foreign entities that are considered to be issuing “payment stablecoins”, which could in turn increase the amount of stablecoin products that could be accepted as margin collateral and alter the competitive landscape for FCMs and DCOs seeking to integrate their operations with tokenized products and the crypto industry.

4. BTC and ETH cannot be deposited as residual interest. The FAQ clarifies that an FCM may only deposit “payment stablecoins” into segregated customer accounts as residual interest (subject to applicable capital charges). In other words, BTC and ETH cannot be deposited into customer accounts as residual interest.

5. Investment of customer funds into payment stablecoins is prohibited. FCMs may not invest customer funds in “payment stablecoins” for any reason. As noted above, an FCM may only deposit “payment stablecoins” in segregated customer accounts if the “payment stablecoins” represent the FCM’s residual interest in the accounts.

6. Crypto-assets cannot be used as initial or variation margin for uncleared swaps. The FAQ explicitly states that crypto assets — including “payment stablecoins” — remain ineligible as initial or variation margin for uncleared swaps between swap dealers or with financial end users. Note, however, that this prohibition in no way brings into question guidance in CFTC Staff Letter 25-39, which provides that a swap dealer may exchange a tokenized form of an already-eligible collateral asset, provided that the tokenized asset satisfies applicable regulatory requirements and grants the holder legal and economic rights that are the same or functionally equivalent to those of the asset in its traditional form. In other words, the FAQ does not call into question whether, as a general matter, FCMs and DCOs can transition their eligible margin collateral into tokenized formats, which may become a trend to the extent the tokenization of cash and cash like instruments (e.g., U.S. dollars and U.S. treasury bonds, and money market shares) becomes a broader trend in the financial services industry.

7. Capital Charges on Proprietary Crypto Assets. In an effort to harmonize guidance from the SEC applicable to broker-dealers, the MPD stated that it would not object if an FCM applied a minimum 20% capital charge on proprietary positions in BTC and ETH, and a 2% capital charge on payment stablecoins, for purposes of computing regulatory capital under Commission Regulation 1.17(c)(5)(ii).

Conditions for FCM Reliance

Before relying on the positions set forth in the prior letters and the FAQ, an FCM must file a notice with the MPD via its WinJammer electronic filing system, specifying the date on which it will begin accepting crypto-assets from customers as margin collateral.  The decision to accept crypto-assets as margin collateral may not be wise for all FCMs.  Following an FCM’s first acceptance of crypto assets from customers, three heightened conditions apply during an initial three-month period:

1. The FCM may accept only payment stablecoins, BTC, or ETH as customer margin collateral, and may deposit only proprietary payment stablecoins as residual interest.
2. The FCM must promptly report any significant operational or system issue, disruption, failure, or cybersecurity incident affecting the use of crypto assets as customer margin collateral, with “significant” defined to include matters involving a significant financial amount, number of customers, or control weakness with the potential for broad impact.
3. The FCM must file weekly reports via the WinJammer system reflecting the total amount of crypto assets held in each of its futures, foreign futures, and cleared swaps accounts, broken out by crypto asset type and customer account class.

After expiration of the initial three-month period, the limitations on acceptable crypto-asset types and the incident reporting condition fall away, and the FCM may accept other crypto-assets as margin collateral, subject to the ongoing conditions set forth in CFTC Staff Letter 26-05. The weekly reporting obligation also terminates at the end of the third calendar month following the month in which the FCM filed its initial notice.

Impact on the Derivatives Industry and Private Funds

Broadly, the FAQ provides a clearer pathway for market participants that wish to incorporate digital assets into their collateral management practices.  Although FCMs and DCOs will likely begin integrating crypto-assets into their collateral management practices, it is clear that there remain bright red lines for the CFTC.  In particular, the exclusion of crypto assets from eligible margin for uncleared swaps remains firm, which greatly limits the utility of digital assets in the bilateral over-the-counter derivatives markets – a market that by some estimates has a notional value in the hundreds of trillions of dollars. Similarly, the prohibition on investing customer funds in “payment stablecoins” reflects a continued cautious approach to the treatment of digital assets in segregated accounts.

For private fund managers, the FAQ has several practical implications. Perhaps most directly, fund managers that trade futures, foreign futures, or cleared swaps through FCMs should expect to see an option to post collateral in eligible crypto-assets.  Similarly, the FAQ may encourage funds to hold more BTC, ETC, or “payment stablecoins” given the ability to post these assets as margin.  This is particularly important to consider given that only non-security crypto-assets may be posted as collateral, even after the initial three-month heightened compliance period.  Furthermore, holding BTC, ETH, and payment stablecoins may become recognized as a means by which to diversify treasury balances away from cash and cash-like instruments, while simultaneously improving capital efficiency, as it may no longer be necessary to liquidate digital asset positions to meet margin calls.

That said, fund managers should be mindful of the applicable haircuts and the phased implementation conditions. Fund managers should coordinate closely with their FCMs to understand the timing, scope, and operational mechanics of any decision by the FCM to rely on CFTC Staff Letter 26-05.
