Deregulation Sounds Like Less Work. But Is It?
Every time a regulator scales back a requirement, the same reaction spreads through compliance teams. Someone says, “Great, one less thing to worry about.” And for a moment, it feels true. Then reality sets in.
The SEC recently approved changes to the Consolidated Audit Trail (CAT) that reduce the collection of personally identifiable information. On paper, that sounds like a win for broker-dealers. Less data to collect. Less data to protect. Less to report. But here’s what a lot of firms miss. CAT compliance was never just about what regulators collect. It’s about how your firm manages its own obligations, day in and day out. Accuracy, recordkeeping, timeliness, and audit readiness don’t disappear just because one data field goes away.
If you’ve been in this industry long enough, you know how this story usually goes. Regulatory relief creates a false sense of ease. Then, months later, an audit reminds everyone that the underlying responsibilities never left.
This is one of those moments. Let’s break down what’s actually changing, and what still needs your full attention.
What Changed Under the CAT/CAIS Amendments?
The SEC-approved amendments to the Consolidated Audit Trail (CAT) modernize how customer information is managed and reported. While these changes reduce the amount of sensitive personal information collected centrally, they do not change the CAT’s core purpose of helping regulators monitor market activity and detect potential misconduct. The amendments are designed to improve data privacy, strengthen cybersecurity, and reduce unnecessary data collection while preserving effective regulatory oversight.
What customer information no longer needs to be reported under CAT?
One of the biggest changes is the removal of certain personally identifiable information (PII) from CAT reporting.
Previously, broker-dealers were required to submit customer information through the Customer and Account Information System (CAIS), including:
- Customer names
- Physical addresses
- Dates of birth
Under the new amendments, firms are no longer required to report these personal details. The SEC introduced this change to reduce the amount of sensitive information stored within CAT. Collecting less PII lowers cybersecurity risks, minimizes unnecessary data retention, and aligns with modern data privacy principles. It’s important to note that this change affects what is reported to CAT, not the records firms are required to maintain internally.
What happened to CAIS?
The Customer and Account Information System (CAIS) is transitioning away from its original role as a centralized repository of detailed customer information. Instead, CAT will use a Reference Database that contains only the information needed to support regulatory reporting and associate customer activity with the correct account. In simple terms, regulators no longer need a centralized database containing extensive personal information. The new framework allows them to perform market surveillance while significantly reducing the amount of sensitive customer data stored within the CAT ecosystem.
What are CCIDs, and why are they being used?
Instead of transmitting customers’ personal information, broker-dealers will now report a Customer and Account Information Identifier (CCID).
A CCID is a unique identifier assigned to a customer account. Rather than sending names, addresses, or dates of birth, firms submit this identifier, allowing the CAT Plan Processor to generate a unique customer reference for regulatory purposes.
This approach offers two important benefits:
- It helps regulators continue linking trading activity to the correct customer account.
- It reduces the need to centrally collect and store sensitive personal information, improving privacy and cybersecurity.
So, what happens to the PII already stored in CAT? The amendments are not limited to future reporting. The CAT Plan Processor is also developing processes to delete the personally identifiable information that has already been submitted to the CAT system. This initiative supports the SEC’s long-term strategy of reducing sensitive data retention while maintaining the effectiveness of market surveillance.
Why did the SEC make these changes?
The amendments reflect a broader shift toward data minimization, which means collecting only the information necessary to achieve a regulatory objective.
By reducing the collection and storage of sensitive customer information, the SEC aims to:
- Strengthen customer privacy
- Reduce cybersecurity risks
- Minimize unnecessary data retention
- Modernize the CAT reporting framework
- Continue supporting effective market surveillance and regulatory oversight
The objective is not to reduce oversight but to achieve the same regulatory outcomes using a more privacy-focused approach.
Does Reduced CAT Reporting Mean Less SEC Oversight?
No. This is perhaps the biggest misconception surrounding the CAT/CAIS amendments.
The changes affect what regulators collect, but they do not reduce a broker-dealer’s responsibility to maintain accurate CAT reconciliation, records, ensure high-quality reporting, comply with applicable SEC and FINRA requirements, or respond to regulatory examinations.
The key takeaway is simple: While CAT reporting requirements have changed, the day-to-day compliance responsibilities within broker-dealer firms remain largely unchanged. Here’s what still deserves your attention.
Why Do Broker-Dealers Still Need Strong Compliance After CAT Deregulation?
This is the part that’s easy to overlook, so it’s worth spelling out clearly.
Maintaining Accurate Data
Clean, reliable data is still the foundation of everything in SEC compliance. Whether or not certain PII fields are collected centrally, your firm’s internal records need to be accurate and complete. Regulators can still request information indirectly, and your data needs to hold up when they do.
Meeting Reporting Requirements
Timelines haven’t changed. Firms still need to submit accurate, complete information within the windows CAT requires. A reduction in one data category doesn’t relax the standards applied to everything else you report.
Staying Prepared for SEC Examinations
SEC examiners don’t just check whether you submitted the right fields. They look at your processes, your documentation, and your controls. Broker-dealer compliance teams should expect that scrutiny to continue, and in some cases, increase, as regulators shift toward relying on ad hoc requests and indirect access methods instead of a centralized database.
Maintaining Audit Trails
Tracking changes to your data, documenting decisions, and preserving your compliance history all remain essential. An audit-ready compliance posture depends on this kind of consistency, regardless of what regulators collect centrally.
Here’s the key takeaway. Regulators may collect less data centrally, but firms remain fully accountable for maintaining accurate and compliant records on their end. The burden hasn’t shifted away from you. If anything, it’s shifted toward your internal systems and processes.
How Smart Firms Are Adapting to Regulatory Changes
Forward-thinking broker-dealers are not viewing deregulation as a reason to reduce their compliance focus. Instead, they are using these changes as an opportunity to improve their overall approach.
Successful firms are:
- Reviewing existing compliance workflows to find gaps before an examiner does
- Improving data management processes so information stays accurate and accessible
- Strengthening governance around who owns what, and how decisions get documented
- Using CAT/CAIS compliance solutions to reduce manual work and human error
- Partnering with experienced compliance professionals who understand where regulatory reporting is headed next
Think of this as a checkpoint. Regulatory change doesn’t have to mean less focus on compliance. It can be the reason your team finally fixes the workflow issues that have been sitting on the back burner for a year.

Whether your firm is adjusting internal processes to reflect the new CAT requirements or simply looking for a more reliable way to stay prepared for regulatory reviews, having the right systems and the right partner in place makes the difference. Compliance shouldn’t feel like a fire drill every time the rules shift. With the right infrastructure, it doesn’t have to.
Future-Proof Your CAT Compliance
Regulations will continue to evolve. Reporting requirements will change. New technologies will reshape how data is collected, stored, and reported. But the foundation of compliance remains the same.
The CAT/CAIS amendments reduce the amount of customer information reported to regulators, not the responsibility of broker-dealers to maintain accurate records, strong internal controls, and audit-ready processes. When regulators need information, your firm must still be able to produce complete, reliable, and well-maintained records. That’s why compliance isn’t just about meeting today’s reporting requirements. It’s about building systems and processes that can adapt to tomorrow’s regulatory changes with confidence.
At Capital Market Solutions, we help broker-dealers stay prepared with reliable compliance solutions that simplify recordkeeping, strengthen reporting accuracy, and support long-term regulatory readiness.

Does CAT deregulation reduce broker-dealer compliance requirements?
No. The 2026 CAT/CAIS amendments reduce certain customer information collected centrally, but they do not eliminate broker-dealers’ responsibility for accurate reporting, recordkeeping, data management, reconciliation, and regulatory readiness. Firms still need strong internal controls and reliable CAT compliance processes
What are the new CAT reporting requirements for broker-dealers?
Broker-dealers still need to maintain accurate customer and account information and meet applicable CAT reporting requirements. Under the updated framework, sensitive customer information is handled differently, with CAT using transformed identifiers and CCIDs to link customer activity while reducing the need to centrally store raw PII.
Is CAIS being eliminated under the new CAT amendments?
CAIS is being replaced by a Reference Database approach rather than simply eliminating the customer-identification function. The updated framework uses CCIDs and reference data to allow regulators to connect customer activity while reducing the amount of sensitive personal information stored in CAT.
