SEC and CFTC Move to Tear Down the Wall Between Their Margin Rulebooks

By Isaac • June 28, 2026 5:55 pm • Comments

The SEC and CFTC are asking the public a question that touches almost every regulated trader: should the two agencies stop running separate margin rulebooks?

On June 26, 2026, the SEC announced a joint request for public comment on harmonizing portfolio-margining frameworks. The CFTC issued the same request in Release 9262-26.

The request covers securities, security-based swaps, futures, swaps, and related positions. That is a wide net.

The agencies said they are evaluating whether greater coordination could improve risk management efficiency, reduce market fragmentation, and enhance customer protections.


This is a request for comment, not a final rule. Nothing has changed yet at the trading desk level.

The questions on the table are technical and serious. The agencies want input on portfolio-margining models, customer protection, cross-margining, capital, segregation, collateral treatment, risk methodologies, clearing, and operational implementation.

SEC announced the June 26 cross-agency request for comment on portfolio-margining frameworks, asking market participants how one margin approach should recognize offsetting risks across products supervised by different agencies. The SEC said the agencies are looking at portfolio margining across securities, security-based swaps, futures, swaps and related positions.

The practical question is whether a regulated firm should have to post duplicate collateral when positions in different markets hedge the same risk. That list matters because it crosses the old boundary between the SEC and CFTC.

Crypto markets live near that boundary every day. A single customer account can touch several of those buckets through hedges, collateral, futures exposure and token-linked products.

Tokens, futures, swaps, event contracts and tokenized collateral regularly cross jurisdictional lines that were drawn for older markets. The release asks how portfolio-margining models should handle offsets, collateral, clearing, customer protection and operational implementation.

Those questions are operational rather than decorative. They decide how much cash or eligible collateral a regulated firm has to lock away before it can carry offsetting positions for customers.

The term sounds technical. The practical effect is collateral.

If offsetting risks can be recognized across products, firms may need less locked-up collateral to run the same regulated business. If the rules stay fragmented, market participants may keep paying for duplication.

That is why this kind of agency plumbing matters to crypto derivatives, tokenized assets and multi-asset trading apps. The next wave of regulated crypto products will need to fit inside margin and clearing frameworks built with traditional assets in mind.

A harmonized approach could make that fit easier, while a fragmented approach could keep capital trapped in separate silos.

CFTC framed the request as a way to improve efficiency while preserving customer protection. The CFTC said greater coordination could improve risk management efficiency, reduce market fragmentation and enhance customer protections.

It also said the public comment period will remain open for 60 days after publication in the Federal Register. The agency is asking about cross-margining, customer protection, capital, segregation, collateral treatment, clearing and operational implementation.

The consumer-protection side is built directly into the question list. The agencies are asking whether capital can move more efficiently without weakening the protections that clearing and margin rules are supposed to provide.

For crypto derivatives, that balance will matter as more products move onto regulated venues. A lighter collateral burden can help markets scale, but only if the risk model holds under stress.


CFTC placed portfolio margining inside a broader SEC-CFTC harmonization initiative for modern market infrastructure. The CFTC harmonization page lists portfolio margining alongside work on data reporting and derivatives product definitions.

It also says the initiative covers traditional financial products as well as emerging technologies and market structures. That broader frame is the reason the story belongs on PCN.

The request spans many markets, and crypto is one of the markets most exposed to unclear jurisdictional lines. When the SEC and CFTC try to harmonize definitions, margin and reporting, they are also shaping the tracks that future crypto products may run on.

The agencies are still in question-gathering mode. Those questions show where the next market-structure fight is moving.

Crypto Briefing connected the technical margin request to the crypto derivatives market. Crypto Briefing said the initiative is aimed mainly at broader markets, while the definitional work will still shape crypto derivatives as the market matures.

That is the right level of caution. The agencies are talking about securities, swaps, futures and related positions, so the release is a general markets move rather than a special crypto rule.

Still, crypto exchanges and brokerages are becoming multi-asset platforms. A unified or better-aligned margin framework can affect which products can be listed together, how collateral is treated and how expensive it is to hedge risk across venues.

For readers, the takeaway is that market structure often changes through technical plumbing before it changes through headline legislation.


Frozen liquidity is real money. When a firm has to post collateral in one silo for securities and another silo for futures, capital that could be working sits idle to satisfy two rulebooks instead of one.

For crypto venues trying to scale regulated products, margin treatment decides how expensive trading becomes. A single framework that nets offsetting positions across asset types is cheaper to operate than two frameworks bolted together.

None of that is guaranteed by a comment request. The agencies could land somewhere narrow, and customer-protection rules will rightly slow any change that touches segregation and collateral.

The signal still counts. Two regulators that spent years talking past each other are now asking, in public and together, whether their walls cost the market more than they protect it.

For crypto readers, the answer to that question will eventually decide how much new product can live inside regulated venues instead of around them.
