SEC Moves to Scrap Rule 611, With Implications for Tokenized Stocks

The SEC has proposed rescinding Rule 611, the order protection rule under Regulation NMS, a move that could carry significant implications for how tokenized stocks interact with U.S. equity market structure.

Rule 611 requires trading venues to route orders to the exchange displaying the best price, a safeguard designed to protect investors from inferior executions. The rule has been a cornerstone of U.S. equity market structure since Regulation NMS took effect in 2007.

What the SEC Is Trying to Change With Rule 611

The SEC’s proposal, outlined in a press release detailing the proposed rescission of Rules 611 and 610(e), signals that the commission believes the current framework no longer fits the modern trading landscape. Rather than a minor technical adjustment, this is a structural overhaul of how trade routing obligations work across national securities exchanges.

Rule 611’s removal would mean trading venues are no longer required to prevent “trade-throughs,” where an order executes at a price worse than the best available quote on another venue. The SEC appears to view this obligation as outdated given changes in market speed, technology, and venue competition since 2007.

SIFMA, the Securities Industry and Financial Markets Association, responded to the proposal. In a statement on the SEC’s proposed amendments to Reg NMS, the trade group acknowledged the significance of revisiting these long-standing market structure rules.

Why Tokenized Stocks Are Part of the Conversation

Tokenized stocks are blockchain-based instruments that represent exposure to listed equities. They sit at the intersection of traditional securities regulation and newer crypto-native trading infrastructure, making them uniquely sensitive to changes in rules like Rule 611.

Under the current framework, any venue offering tokenized versions of U.S. equities must navigate the same best-execution and order routing requirements that apply to traditional exchanges. Rule 611’s removal could alter the compliance landscape for platforms offering these products, particularly around how they handle price discovery and execution obligations.

It is worth distinguishing between tokenized stock access and direct ownership of listed shares. Most tokenized stock products offer synthetic or derivative exposure rather than direct share ownership, but they still reference the prices set by regulated exchanges. Changes to how those exchanges route orders could ripple into how tokenized products are priced and discussed by issuers.

This regulatory shift arrives as governments globally continue wrestling with how to regulate crypto-linked financial products, making the SEC’s approach a closely watched signal for international regulators as well.

What Crypto Investors and Platforms Should Watch Next

The proposal will go through a standard SEC rulemaking process, including a public comment period before any final rule is adopted. The timing and final language of the rule matter considerably, as implementation details will determine how tokenized stock platforms and broker-dealers need to adjust.

The main stakeholder groups affected include tokenization platforms, traditional broker-dealers that may compete with or integrate blockchain-based execution, national securities exchanges, and retail investors who use crypto platforms for equity exposure. Platforms that offer stock and crypto price tracking tools will also need to monitor how routing changes affect the data they display.

In the near term, the impact is more likely to be narrative and compliance-related than operational. No trading infrastructure changes immediately upon a proposal. But platforms building tokenized stock products should begin assessing how their execution models align with a post-Rule 611 environment, particularly as enforcement priorities around securities compliance in crypto markets continue to intensify.

Market participants should watch for the comment period deadline, any revisions to the proposed rule text, and whether the SEC signals broader Reg NMS reforms that could further reshape the intersection of traditional and tokenized equity markets.
