U.S. financial regulators the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) have opened a formal joint public comment period to align portfolio margining frameworks for cross-market portfolios. The request for comment is issued jointly as SEC Press Release 2026-59 and identically numbered CFTC Press Release 2026-59, per the agencies’ joint announcement published on the SEC newsroom and corresponding release on the CFTC’s official newsroom.
The harmonization effort targets portfolios holding both SEC-regulated securities — including listed equities, exchange-traded funds, and equity options — and CFTC-regulated derivatives contracts, including broad-based index futures, single-stock futures, and options on futures.
Current Dual-Regime Margin Requirements for Cross-Market Firms
Current U.S. regulations require firms to calculate margin for securities positions under the SEC’s portfolio margining rules, and for derivatives positions under the CFTC’s separate margining regime. This applies even when both position types are held in the same client or firm portfolio, creating redundant capital requirements for cross-market operators.
Offset positions in highly correlated assets — such as S&P 500 index futures and SPDR S&P 500 ETF shares — cannot be netted across the two regulatory frameworks under existing rules, per the joint 2026-59 release.
This duplicative requirement increases capital costs for firms that operate across both securities and derivatives markets, as they must hold separate reserves for economically offsetting positions held in different regulatory wrappers.
Three Core Areas Open for Public Comment
The joint request for comment invites input on three targeted areas to resolve the duplicative margin requirement. First, methodologies for netting offsetting positions across SEC and CFTC asset classes.
Second, standardized margin calculation formulas that apply uniformly to both securities and derivatives. Third, operational requirements for firms implementing a unified margining process, per the joint release.
The agencies have structured the comment request to gather specific, actionable feedback on each of these three pillars to inform a future proposed rule for aligned margining.
Parallel SEC Regulatory Alignment for Related ETF Products
The portfolio margining harmonization aligns with a separate ongoing SEC regulatory proceeding: the agency’s 2026-60 request for comment on novel exchange-traded funds. That proceeding covers leveraged, inverse, and commodity-linked ETFs that are frequently held alongside derivatives in institutional portfolios.
Aligned portfolio margining rules would apply to many of the products covered in the 2026-60 comment process, per the joint 2026-59 release.
This parallel initiative means that feedback submitted on the 2026-59 margining harmonization may also inform margin requirements for the novel ETF products under review in the 2026-60 proceeding.
Eligible Commenters and Submission Process
Five core regulated groups are explicitly encouraged to submit feedback on the harmonization proposal: SEC-registered broker-dealers, CFTC-registered futures commission merchants, swap dealers, institutional investors that maintain cross-market portfolios, and industry trade groups representing these entities. The agencies also welcome input from any interested party, including investor advocacy groups and members of the general public, per the joint release.
All submissions must be filed via the SEC’s public comment portal for the 2026-59 release. All feedback received will inform the agencies’ final margining framework alignment proposal, per the joint release.
Implementation Factors and Rulemaking Timeline
Beyond the three core comment areas, the agencies will consider input on three additional implementation-related factors. These include timelines for rolling out aligned margining rules, grandfathering provisions for existing cross-market portfolios, and cross-border margin coordination for firms operating in international markets, per the joint release.
The agencies have not specified a fixed timeline for final rule adoption in the initial 2026-59 request for comment. A separate proposed rule will be published for public comment prior to finalizing the aligned margining framework, but no estimated publication date for that proposed rule was provided in the initial request, per the joint release.
