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.
