FINRA Rule 4210

The Financial Industry Regulation Authority (FINRA) filed for a rule change with the Securities and Exchange Commission (SEC). Recognized as “FINRA Rule 4210,” this will require 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   

FINRA Rule 4210 is postponed until March 25, 2021. But is your firm prepared to meet these requirements? Being proactive before this upcoming implementation date is essential.
