The Securities and Exchange Commission (SEC) has adopted amendments to Rule 15c3-3, commonly known as the Customer Protection Rule, implementing significant updates to the frequency of reserve calculations for broker-dealers. The changes are aimed at bolstering protections for customer assets and enhancing financial stability within the securities markets.

Key Changes to Rule 15c3-3

The SEC’s amendments introduce two primary adjustments:

1. Daily Computation Requirement for Larger Broker-Dealers
   Broker-dealers with average total credits of $500 million or more — representing the net cash owed to customers and Proprietary Accounts of Broker-Dealers (PAB account holders) — must now compute their reserve requirements daily instead of weekly.

   • The rule aims to reduce discrepancies between actual reserves and customer obligations, ensuring timely coverage of newly deposited funds.

   • This requirement applies to broker-dealers exceeding the $500 million threshold based on the 12-month FOCUS Reports from July 2024 to June 2025. These broker-dealers must begin daily computations no later than December 31, 2025.

2. Reduction in the Reserve “Buffer” for Daily Computations
   Broker-dealers performing daily reserve computations will see a reduction in the buffer for customer-related receivables (aggregate debit items) from 3 percent to 2 percent. This adjustment reflects increased confidence in the protection afforded by daily calculations.

SEC Chair Gary Gensler commented, “Our markets have dramatically evolved since the 1972 adoption of the Customer Protection Rule. These amendments enhance trust in our financial system by safeguarding customer assets and reducing potential risks to the Securities Investor Protection Corporation Fund.”

Enhanced Customer Asset Protections

The transition from weekly to daily computations provides dynamic oversight of customer funds. By closely matching cash obligations with reserve deposits, broker-dealers will more effectively mitigate risks associated with large deposit shortfalls. In the event of a financial failure, this measure reduces the likelihood of delays in returning cash and securities to customers and PAB account holders.

Voluntary Daily Computations and Notification Requirements

The amendments also allow broker-dealers not meeting the $500 million threshold to voluntarily adopt daily reserve computations and apply the reduced buffer, provided they notify their designated examining authority at least 30 days in advance.

Effective Date and Compliance Timeline

The amendments take effect 60 days after publication in the Federal Register. For broker-dealers subject to the new rules, compliance with daily computations must commence by December 31, 2025.

Implications for Broker-Dealers

These amendments present both operational challenges and opportunities for broker-dealers:

• Operational Impact: Firms must enhance their systems to handle daily reserve computations, ensuring alignment with SEC requirements.

• Strategic Considerations: Eligible broker-dealers may voluntarily adopt the daily computation framework to benefit from the reduced buffer, potentially improving capital efficiency.
