SUMMARY: The OCC, Board, FDIC, FCA, and FHFA (collectively, the Agencies) are requesting comment on a proposal to establish minimum margin and capital requirements for registered swap dealers, major swap participants, security-based swap dealers, and major security-based swap participants for which one of the Agencies is the prudential regulator. This proposed rule implements sections 731 and 764 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which require the Agencies to adopt rules jointly to establish capital requirements and initial and variation margin requirements for such entities on all non-cleared swaps and non-cleared security-based swaps in order to offset the greater risk to such entities and the financial system arising from the use of swaps and security-based swaps that are not cleared.

DATES: Comments should be received on or before June 24, 2011.​
