The U.S. Securities and Exchange Commission (SEC) has released a new proposal to amend the Order Protection Rule (Rule 611) under the Reg NMS regulations. The commission stated that the existing rules are contributing to increased routing costs and market fragmentation, necessitating a structural update. This proposal is part of the SEC's broader effort to modernize market infrastructure and enhance trading efficiency for all participants.
This regulatory shift occurs as U.S. equity markets grapple with intense competition between traditional exchanges and alternative trading systems, where liquidity fragmentation often leads to wider spreads. Compared to previous reform attempts in late 2022, this proposal specifically targets the inefficiencies in how orders are routed across fragmented venues. Per market data, execution costs remain a primary concern for institutional and retail traders navigating the complex U.S. exchange landscape.
