FINRA recently proposed extending the implementation date of certain amendments to FINRA Rule 4210, from March 25, 2021 to October 26, 2021. This was filed for immediate effectiveness; however, the SEC has not yet filed to publish this change.

According to commentary by Nihal Patel, “The amendments establish margin requirements for various types of forward-settling agency transactions, including TBAs, specified pool and collateralized mortgage obligation transactions. FINRA noted that this is not the first time it has delayed the implementation, though certain risk limit determination requirements of the amendments remain in effect.”


FINRA Rule 4210 requires the implementation of mandatory margin requirements for:

  1. Specified Pool Transactions
  2. Covered Agency Transactions 
  3. TBA Transactions 

According to FINRA, this upcoming Rule “describes the margin requirements that determine the amount of collateral customers are expected to maintain in their margin accounts, including both strategy-based margin accounts and portfolio margin accounts.” It further explains the margin requirements for equity securities, fixed income securities, options, warrants and security futures. The objectives of FINRA Rule 4210 include:

  1. Address systematic risk concerns
  2. Establish monitoring of uncollected margin
  3. Promote a coherent margin requirements framework
  4. Reduce counter-party default risk exposure via collateralization process implementation
