The SEC Published Rule 4210 Amendments to the Federal Register

On May 25, 2021, The Securities Exchange Commission (SEC) published the amendments of FINRA Rule 4210 to the Federal Register.

The Financial Regulatory Authority (FINRA) has proposed to amend the requirements for Covered Agency Transactions under FINRA Rule 4210 (Margin Requirements) as approved by the SEC.

The text of the proposed rule change is available on FINRA's website at, at the principal office of FINRA and at the Commission's Public Reference Room.

According to the Federal Register, a summary of FINRA's proposed amendments are as follows:

  • To eliminate the two percent maintenance margin requirement that applies to non-exempt [18] accounts pursuant to paragraph (e)(2)(H)(ii)e. under Rule 4210. This would eliminate the need for members to distinguish exempt account customers from other customers (“non-exempt accounts”) for purposes of Covered Agency Transaction margin. As such, without regard to a counterparty's exempt or non-exempt account status, members would collect margin for each counterparty's excess mark to market loss, as discussed in further detail below, unless otherwise provided by the rule;
  • Subject to specified conditions and limitations, to permit members to take a capital charge in lieu of collecting margin for excess net mark to market losses on Covered Agency Transactions. These conditions and limitations are designed to help protect the financial stability of members that opt to take capital charges while restricting the ability of the larger members to use their capital in lieu of collecting margin to compete unfairly with smaller members; and

  • To make revisions designed to streamline, consolidate and clarify the Covered Agency Transaction rule language. These revisions will preserve and clarify key exceptions to the requirements, including for example the $250,000 de minimis transfer exception [19] and the $10 million gross open position exception [20] established pursuant to SR-FINRA-2015-036.
