SEC proposes significant changes to current market structure

Abstract

The SEC has proposed several rules and rule amendments that, if adopted, would impact market structure of the equities markets for years to come. This article summarizes those proposed changes and describes some of the early reaction to them by both industry and regulators. Regulation NMS, as the rule proposals are collectively called, is intended to accomplish three primary objectives: (1) to promote equal regulation of market centers, (2) to update antiquated rules, and (3) to promote greater order interaction and displayed depth. Regulation NMS, which is intended to “advance the dialogue” on market structure issues, consists of rule proposals in four substantive areas. First, the SEC has proposed a uniform trade‐through rule for all national market system (“NMS”) market centers that would affirm the principle of price priority while addressing the differences between automated and manual markets. Second, the SEC has proposed a uniform market access rule with a de minimis fee standard intended to assure non‐discriminatory access to the best prices displayed by NMS market centers without mandating hard linkages such as the Intermarket Trading System (“ITS”).
