Consolidated Audit Trail (CAT)


In November 2016, the Securities and Exchange Commission approved a national market system (NMS) plan that required national securities exchanges and national securities associations ("SROs") to create a single, comprehensive database known as the Consolidated Audit Trail (CAT) that it stated will enable regulators to more efficiently and thoroughly track all trading activity in U.S. equity and options markets. FINRA has been selected as the processor for CAT.

Some important milestones on the SEC’s current schedule for implementing CAT are as follows:

Event Date
CAT Registration by Industry Members March 18, 2019 – June 27, 2019
Annual Clock Synchronization and Certification March 15 of Each Year
Industry Testing and Validation for Equities December 2019
Equity Go-Live April 2020
Industry Testing and Data Validation for Options December 2019
Options Go-Live May 2020

What IBKR Clients Need to Know

An IBKR client falls under the rule and is obligated to report to CAT if they are a member of a U.S. national securities exchange or a U.S. national securities association that handles orders or quotes in NMS equity securities, OTC equity securities or listed options. Unlike the current OATS reporting obligation, the CAT reporting obligations extend the scope of covered instruments to options too.

We recommend that such clients become familiar with the rules that are available on the regulator’s website:

Please note that the CAT Rules do not provide for any firms to be excluded or exempted from the CAT reporting obligation.

IBKR will offer CAT reporting services for its clients that are obligated to CAT report.

  • If your firm would like to contract with IBKR to handle CAT reporting, please complete the CAT Declaration page that is available on the website at:

  • If you elect to have IBKR handle CAT reporting for you, IBKR will provide you with a CAT Reporting Agreement for signature. We expect to provide these soon, after FINRA publishes its best practices for these agreements. Your firm will also need to update its own policies and procedures in accordance with the CAT Rules.

Although the CAT Industry Member Technical Specifications continue to be amended and revised, IBKR is working to comply with the requirements outlined so far.

We will provide additional information about testing and CAT reporting efforts as it becomes available.

Regulation Best Interest and Form CRS

On June 5, 2019, the Securities and Exchange Commission (SEC) adopted a package of rulemakings and interpretations designed to enhance the quality and transparency of retail investors’ relationships with investment advisers and broker-dealers, bringing the legal requirements and mandated disclosures in line with reasonable investor expectations, while preserving access (in terms of choice and cost) to a variety of investment services and products. Specifically, these actions include new Regulation Best Interest (Reg BI), the new Form CRS Relationship Summary (Form CRS), and two separate interpretations under the Investment Advisers Act of 1940.

According to the SEC, these actions are designed to enhance and clarify the standards of conduct applicable to broker-dealers and investment advisers, help retail investors better understand and compare the services offered and make an informed choice of the relationship best suited to their needs and circumstances, and foster greater consistency in the level of protections provided by each regime, particularly at the point in time that a recommendation is made.

A copy of IBKR’s Form CRS and responses to the conversation starters in the Form CRS are publicly available here:

Introducing Brokers and Financial Advisors

The Form CRS above is specific to IBKR and addresses the nature and scope of services provided by IBKR, the types of fees customers of IBKR will incur, potential conflicts of interest, and IBKR’s disciplinary history. The document does not address compliance and legal obligations of IBKR’s clients that have their own customers (e.g. introducing brokers, financial advisors, registered investment advisors, etc.).

At this time, IBKR does not provide a regulatory solution for introducing brokers and financial advisors to meet their Reg BI and Form CRS obligations.

IBKR clients with underlying clients of their own should consult with independent counsel to determine their obligations under Reg BI and Form CRS.
