SEC Adopts Rules Modifying Minimum Pricing Increments, Access Fee Caps, and Order Transparency

On September 18, 2024, the SEC unanimously adopted new rules modifying key aspects of the National Market System (NMS). These amendments affect minimum pricing increments, access fee caps, and order transparency for NMS stocks. The changes, effective in 2025 and 2026, aim to reduce trading costs, enhance market transparency, and better align pricing structures across different stock categories. Notably, the updates will influence trading strategies, compliance measures, and market behaviors, potentially triggering challenges from stock exchanges and other market participants.
