SEC and CFTC Call for Public Input on Harmonized Margin Rules for Securities and Derivatives
The SEC and CFTC are jointly seeking public feedback on unified portfolio margin rules covering securities and derivatives, as crypto derivatives and multi-asset trading continue to expand rapidly.

The U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) have jointly issued a call for public commentary on the development of unified portfolio margin rules that would span both securities and derivatives markets. This initiative comes as cryptocurrency derivatives and multi-asset trading platforms continue to grow at a rapid pace, raising new challenges for regulators tasked with overseeing financial stability.
At the heart of the request is the question of cross-margining — a practice that allows traders to offset positions across different asset classes in order to reduce the total collateral required. While this can improve capital efficiency for market participants, it also introduces complex risk management considerations that regulators are keen to address in a consistent and transparent manner.
Both agencies are particularly focused on how collateral requirements should be structured in environments where traditional securities and derivative instruments are traded alongside digital assets. The rapid expansion of crypto derivatives has blurred the lines between markets that were historically governed by separate regulatory frameworks, prompting the SEC and CFTC to explore a more cohesive approach.
Public feedback is being sought on a range of issues, including how cross-margining arrangements should be supervised, what standards should govern collateral eligibility, and how systemic risk can be mitigated when positions span multiple asset categories. Regulators are also looking for input on how existing rules might be adapted — or entirely rewritten — to better reflect the realities of modern multi-asset trading.
The joint effort signals a growing recognition among U.S. regulators that siloed oversight may no longer be adequate in an era of increasingly interconnected financial markets. As digital assets become a more prominent fixture in institutional portfolios, the pressure to establish clear, consistent rules has intensified.
Market participants, industry groups, legal experts, and individual investors are all encouraged to submit their views. The agencies have indicated that the input received will inform future rulemaking efforts aimed at creating a more unified regulatory landscape for portfolio margin across securities and derivatives.
This development is being closely watched by the crypto industry, which has long called for greater regulatory clarity. A harmonized framework could help reduce compliance uncertainty for firms operating across both traditional and digital asset markets, while also providing stronger protections for investors navigating an increasingly complex trading environment.
