The Consolidated Audit Trail: Time for a Fundamental Reset?

Why It Matters

Shifting CAT to direct SEC control could dramatically improve market surveillance efficiency while curbing costly governance disputes, strengthening overall market integrity.

Key Takeaways

• CAT's NMS Plan structure leads to costly governance disputes.
• SEC ownership would streamline surveillance and funding via Congress.
• Recent exemptive orders lower costs but lack long‑term certainty.
• Industry faces 'CAT fatigue' after a decade of implementation challenges.
• Comment deadline June 22, 2026 offers rare chance for reform.

Pulse Analysis

The Consolidated Audit Trail was conceived as a comprehensive, real‑time repository of order and execution data to bolster the SEC’s ability to detect market abuse. By embedding CAT within the Regulation NMS framework, the agency created a hybrid utility owned by the major self‑regulatory organizations. Over the past decade, that governance model has produced chronic disagreements over scope, funding, and technical specifications, inflating costs and prompting multiple exemptive orders to keep the project afloat.

Advocates for a structural overhaul argue that direct SEC ownership would resolve the inherent conflict of interest that plagues the current joint‑governance model. With the Commission at the helm, funding could flow through the congressional appropriations process, ensuring transparent budgeting and eliminating the need for costly industry‑assessed fees. Moreover, a single accountable entity would streamline data access for surveillance, enforcement, and rulemaking, mirroring the efficiency seen in other SEC‑run market utilities such as the consolidated tape.

The industry, however, is experiencing "CAT fatigue" after years of building reporting infrastructure, testing specifications, and navigating regulatory uncertainty. The SEC’s April 16, 2026 Concept Release, which solicits comments on whether CAT should remain an NMS Plan or transition to SEC control, presents a narrow window for stakeholders to influence the outcome. Firms that engage constructively can help shape a more sustainable, cost‑effective audit trail, while those that remain passive risk being locked into a legacy system that may never fully meet its intended regulatory purpose.
