CFTC and SEC Set Comment Deadline for Portfolio and Cross-Margining Proposal

The CFTC and the SEC set a comment deadline of August 31, 2026, on their joint request for comment on allowing further portfolio margining and cross-margining of securities and derivatives.

The agencies noted that traders increasingly hold related positions across cash securities, options, futures, and swaps, but current rules split these into separate accounts with different margin requirements. The result is that margin calculations miss offsetting exposures - tying up capital and raising liquidity demands without improving market stability (see prior coverage.)
