The US Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) have launched a joint public consultation focused on aligning portfolio margin rules across securities and derivatives markets. The agencies say the goal is to reduce fragmentation between frameworks that can apply to similar trading and risk management structures—particularly as market participants expand across both regulated categories.
The SEC and CFTC are seeking feedback on how cross-margining could work in practice, including collateral treatment, risk management expectations, and customer protections. They also want input on how any changes might affect market liquidity and competition. The consultation will run for 60 days after the proposal is published in the Federal Register.
Key takeaways
- The SEC and CFTC are jointly reviewing portfolio margin rules with the explicit aim of enabling broader cross-margining across securities and derivatives.
- Cross-margining could reduce the amount of collateral required when positions are economically offset, because margin would reflect portfolio risk rather than isolated trades.
- The consultation asks market participants to weigh collateral, risk controls, and customer protection considerations—along with potential impacts on liquidity and competition.
- The review comes as crypto derivatives expand through US-regulated venues tied to both CFTC and SEC oversight.
Why the SEC and CFTC are looking to harmonize margin rules
Portfolio margin systems allow firms to calculate margin based on the overall risk of a portfolio rather than treating positions as separate silos. Under cross-margining, offsetting positions across different products can be recognized together, which can lower margin requirements—especially for hedged strategies.
In remarks accompanying the consultation, SEC Chair Paul Atkins said cross-margining presents an opportunity to unlock liquidity that may otherwise be “frozen” in separate accounts. He also argued that harmonizing the agencies’ frameworks could help avoid jurisdictional overlap becoming a brake on innovation and market efficiency.
Practically, the SEC and CFTC are asking questions about where the current systems diverge and what would be required to make cross-margining operational across the boundary between securities and derivatives regulation. The agencies are not only focused on margin math; they are also raising broader implementation issues such as collateral handling, risk management processes, and the customer-facing protections that should accompany any shift in how margin is calculated.
What cross-margining changes for hedged strategies
Cross-margining matters because derivatives and structured products often come in combinations where risk is intentionally offset. Instead of requiring margin for each leg of a trade independently, cross-margining can treat a hedged portfolio as a single risk profile.
When recognized offsets reduce the required collateral, firms can potentially redeploy capital to other strategies. The SEC’s and CFTC’s consultation frames this as a liquidity issue: margin that is tied up in separated accounts could become more available if portfolio-based margining is permitted more broadly across markets.
At the same time, the agencies are probing for safeguards. Any framework that allows offsets across regulatory boundaries raises questions about who bears which risks, how margin models should be validated, and whether customer protections remain consistent when accounts and positions are economically linked.
Crypto derivatives growth highlights the regulatory overlap problem
The agencies’ joint consultation lands at a moment when crypto derivatives are increasingly offered through multiple regulated channels in the US—channels that can implicate different regulators depending on the product structure.
Recent approvals show how the ecosystem is broadening. On May 29, the CFTC approved Bitcoin perpetual futures for prediction market platform Kalshi. Around the same time, the CFTC cleared Coinbase Financial Markets to offer eligible US institutional clients access to certain Deribit-listed crypto options and perpetual futures, and Coinbase began offering the access the same day through its integration with Deribit. A few weeks later, Kraken launched CFTC-regulated perpetual futures for eligible US users through its recently acquired Bitnomial platform, expanding domestic derivatives offerings beyond CME-listed crypto futures.
As options, perpetuals, and futures become more widely available across venues, the underlying question of margin alignment becomes more than an abstract policy concern. If firms can face different margin regimes depending on where a contract is classified—or which regulator has primary oversight—liquidity can become fragmented even when economic risk is closely related.
That fragmentation is one reason the SEC and CFTC’s consultation is likely to matter to exchanges, brokerages, and market makers building cross-venue strategies, as well as to institutional traders managing hedges across multiple product types.
Broader concerns over applying older frameworks to new products
The consultation also reflects the tension regulators face when existing market structures meet novel trading categories. Earlier this week, CFTC Chair Mike Selig said cryptocurrency perpetual futures were not a “natural fit” for traditional commodity markets, such as agriculture, pointing to the practical challenges of mapping established frameworks onto assets and trading dynamics that don’t neatly match prior assumptions.
That observation underscores why the SEC and CFTC are not only focused on cross-margining mechanics, but also on whether risk management expectations and customer protections can be aligned without weakening oversight. In crypto, where products frequently blur the lines between trading use cases, the margin framework becomes an area where regulation can either constrain or facilitate efficient hedging.
If harmonization succeeds, the main change for market participants would be the ability to more consistently evaluate hedged exposures across products and jurisdictions—potentially reducing duplicative collateral requirements. If it fails or is limited, firms may still find that regulatory separation leads to higher capital lock-up and less efficient portfolio risk handling.
For now, market participants should watch the SEC and CFTC’s consultation details as the comment period approaches, focusing on how the agencies propose to structure cross-margining eligibility, collateral treatment, and risk controls—and how they intend to balance liquidity benefits against supervisory and customer-protection requirements.
