FINRA CAT Compliance in 2025: A Game-Changer for Regulatory Transparency and Trade Surveillance

In the ever-evolving landscape of financial regulation, one initiative has transformed the way U.S. capital markets are monitored and governed: the Consolidated Audit Trail (CAT). Spearheaded by the Securities and Exchange Commission (SEC) and enforced by FINRA, CAT is designed to centralize, standardize, and modernize the audit trail for all U.S. equity and options markets.

CAT is not just another reporting mandate-it's a systemic overhaul of how regulatory bodies gather, analyze, and act on trading data. With the introduction of RSMS and CATalystTM by Capital Market Solutions, firms can now navigate the complexity of CAT with unmatched precision and operational ease.

What Is the FINRA CAT?

The Consolidated Audit Trail (CAT) is a comprehensive tracking mechanism created under SEC Rule 613, requiring broker-dealers and trading venues to report data on every order, execution, cancellation, and modification in the U.S. equity and options markets. Unlike legacy systems like OATS, CAT offers a holistic, end-to-end view of the trading lifecycle.
It is split into two primary segments:
Event Data Repository: Tracks all trading activity with nanosecond-level timestamps.

Customer and Account Information System (CAIS): Collects detailed identity and account information about trading participants.

Together, these components offer regulators unprecedented oversight into market behavior.

Why CAT Is a Milestone in Market Surveillance
The primary objective of CAT is to improve transparency, detect abusive behavior, and safeguard retail and institutional investors. It allows FINRA and the SEC to reconstruct trading scenarios across different platforms and participants, closing gaps that bad actors once exploited.
CAT has also enabled regulators to:
Detect insider trading patterns more effectively.

Identify order spoofing and layering tactics.

Monitor systemic risks with broader contextual insight.

2025 Update: Regulatory Shifts Around Personal Data
While the CAT's goal of transparency is universally acknowledged, its handling of personal data-especially for individual investors-has been met with growing concern.
In early 2025, the SEC approved a rule modification permitting firms to omit personally identifiable information (PII) such as full names and addresses when reporting through CAIS. This exemption was applauded by the industry and reflects a broader move toward data minimization in financial reporting.
FINRA has since expressed its intent to fully remove previously submitted PII, pending final SEC approval. This ongoing evolution underscores the balance regulators are striving to maintain between transparency and data privacy.

Compliance Challenges: Why Many Firms Struggle
Although CAT was introduced to streamline regulatory oversight, its execution has introduced new operational pressures on broker-dealers, particularly smaller firms. Key compliance challenges include:
Clock synchronization issues leading to timestamp errors.

High volume of late or inaccurate submissions resulting in regulatory scrutiny.

Inadequate Written Supervisory Procedures (WSPs) that fail to align with CAT-specific responsibilities.

Complexities in merging order data with CAIS submissions.

FINRA has ramped up its enforcement efforts in 2025, actively auditing firm submissions and handing out penalties for systemic reporting failures.

RSMS and CATalystTM: Empowering Smarter Compliance
To help market participants meet these requirements, Capital Market Solutions has developed two purpose-built platforms:
Regulatory Surveillance & Management System (RSMS)
Automates CAT/CAIS submissions across multiple asset classes.

Detects reporting errors in real-time.

Supports exception management with a built-in escalation workflow.

Provides full audit trails to ensure end-to-end transparency.

CATalystTM Analytics Suite
Converts raw CAT data into actionable insights.

Enhances monitoring of compliance trends and exceptions.

Offers visualization tools for internal reviews and audits.

Helps firms preempt regulatory penalties through predictive analytics.

These solutions are especially critical for firms juggling CAT with other regulatory obligations like SEC Rule 606, MiFID II, and Dodd-Frank requirements.

Future Outlook: What Lies Ahead for FINRA CAT
As we move into the latter half of 2025 and beyond, more enhancements and possibly additional phases of CAT are expected. These may include:
Expanded use of AI to analyze trading data at scale.

Further refinements to CAIS exemptions and PII controls.

Increased alignment with global regulatory standards, including EU and APAC equivalents.

Firms that act now to solidify their CAT infrastructure will be far better positioned to adapt to these changes without disrupting daily operations.
