With only weeks remaining before the June 30, 2026 compliance deadline, carrying broker-dealers face urgent operational and regulatory risk if they have not finalized the transition from weekly to daily customer and Proprietary Accounts of Broker-Dealers (PAB) reserve computations. Amendments to Exchange Act Rule 15c3-3 fundamentally change the cadence of the SEC's Customer Protection Rule, and firms that have delayed implementation should treat the coming weeks as a critical compliance sprint.
Under the amended rule, carrying broker-dealers must perform dailyΓÇörather than weeklyΓÇöreserve computations for both customer and PAB accounts beginning June 30, 2026. This represents a significant operational shift from the long-standing weekly computation cycle. The SEC extended the original December 31, 2025 deadline specifically to give carrying broker-dealers additional time to implement the accounting and operational changes necessary to support a daily computation framework. That extension, however, was not open-ended, and the June 30, 2026 date is now firmly in view.
To meet the deadline, firms must complete a coordinated set of implementation steps. Accounting and reserve computation systems must be upgraded to support daily processing volumes and the corresponding data flows. Testing protocols should be established and executed to validate the accuracy of daily computations, including reconciliation against historical weekly results. Personnel responsible for treasury, operations, and regulatory reporting functions will need targeted training to manage daily workflows, exception handling, and the heightened cadence of internal review and approval.
Compliance is not limited to Rule 15c3-3 alone. The amendments are accompanied by a related Rule 15c3-1 net capital buffer adjustment, which must be implemented in tandem. As a result, carrying broker-dealers should conduct a coordinated review of both their reserve computation processes and their net capital calculations well before the deadline. A siloed approach risks gaps that could surface during examination or in the firm's own internal certifications.
Firms that have not yet finalized their implementation roadmap should prioritize remediation immediately, with particular focus on system readiness, testing completion, and documentation of controls.
