US Stock Market: Citadel Securities warns SEC rule change could hurt retail investors, market liquidity
Economic Times 1 hr ago·18 Aug 2026, 4:07 am
Citadel Securities, a major market maker, has urged the U.S. Securities and Exchange Commission (SEC) to reconsider a proposed rule change. The firm warns that eliminating the order protection rule could reduce market liquidity and weaken price discovery. This rule currently ensures that trades are executed at the best available price across the market. If it is removed, Citadel argues that trading could shift away from public exchanges, potentially harming retail investors who rely on these venues for fair pricing.
This proposal matters to investors because market liquidity and price discovery are vital for efficient trading. A drop in liquidity can lead to wider bid-ask spreads, making it more expensive for retail investors to buy or sell shares. Citadel has suggested alternatives, such as setting minimum trading volume thresholds for exchanges to qualify for protected status. Investors should watch for the SEC's final decision and how other market participants react to this proposal.
