In June 2026, the SEC and CFTC jointly sought public comment on possible ways to harmonize portfolio-margining frameworks spanning securities, security-based swaps, futures, swaps and related positions. The agencies said they were evaluating options; the request itself did not create a new customer margin entitlement or change existing requirements.

Risk models, customer protections and statutory responsibilities may constrain any common framework.
Regulators asked how related positions could be margined together
The SEC and CFTC issued a joint request for public comment on 26 June 2026 about potential approaches to greater alignment of portfolio-margining requirements across securities, security-based swaps, futures, swaps and related positions. The agencies framed the exercise around possible risk-management efficiency, reduced fragmentation and customer protection.

The questions covered existing models, cross-product offsets, capital and segregation, collateral treatment, margin methodologies, clearing organisations, technical implementation, liquidity and competition. The public-comment period was stated as 60 days after publication in the Federal Register; the source release does not say that the agencies adopted a final framework.

The SEC and CFTC have different statutory responsibilities, and the request says any coordination must remain consistent with each agency’s authority. That qualifier places customer-asset protection and legal boundaries alongside possible capital efficiency. SEC and CFTC: Joint request for public comment on portfolio margining, 26 June 2026
Cross-margining can reduce duplicated collateral while adding operational demands
If positions across products can be offset under a permitted model, a firm or customer might need less gross collateral than under separate calculations. Whether that is appropriate depends on the positions’ risk, the model’s assumptions, the clearing arrangement and the way customer funds remain protected. The agencies asked for evidence on both efficiency and safeguards. SEC and CFTC: Joint request for public comment on portfolio margining, 26 June 2026
For brokers and clearing firms, any eventual change could require compatible position data, stress testing, collateral allocation, default management and reporting. Technical interoperability alone would not decide which offsets qualify or how customer assets are segregated.
An important alternative is that the agencies retain separate requirements where risks or statutory frameworks cannot be aligned safely. A consultation signals that options are being considered; it does not establish that a broader cross-margining facility will be approved or when it would become available.
Look for rulemaking text before changing margin assumptions
Read any later agency proposal or final rule for its scope, eligible products, calculation method, customer protections and implementation dates. The June request is an input-gathering document; it should not be used as a substitute for a firm’s current margin disclosures or clearing agreement.

For a broker, the practical test is whether it can explain which positions receive offsets, how stress scenarios are handled and what happens when the customer’s portfolio changes. Ask whether figures shown in an account include house add-ons, intraday requirements or jurisdiction-specific restrictions.
Investors should not assume that a consultation will lower their own margin. A proposal could change calculations only for participating entities or selected products and could introduce eligibility conditions. Until formal action is published and implemented, existing account-level requirements remain the operative reference.
