SEC Plan to Scrap Rule 611 Could Affect Crypto Tokenized U.S. Stocks

The U.S. Securities and Exchange Commission has proposed rescinding Rule 611 of Regulation NMS, a move that could have ripple effects for crypto platforms offering tokenized versions of U.S. equities.

What the SEC Is Proposing With Rule 611

Rule 611, also known as the Order Protection Rule, has been a cornerstone of U.S. equity market structure since 2005. It requires trading venues to prevent “trade-throughs,” ensuring that orders are executed at the best available price across all national exchanges.

The SEC’s proposal to rescind Rules 611 and 610(e) would eliminate this protection, allowing venues to compete on factors beyond price alone, such as speed, access, and execution quality. The commission argues the rule may no longer serve its original purpose in today’s fragmented, high-speed markets.

Without Rule 611, brokers and trading platforms would no longer be obligated to route orders to whichever exchange displays the best quote. This could increase competition among venues but also introduce wider price discrepancies across markets.

Why Tokenized U.S. Stocks Could Be Exposed

Crypto platforms that offer tokenized exposure to U.S. equities typically rely on the underlying stock market’s pricing infrastructure to maintain accurate valuations. These tokenized products, whether structured as synthetic assets or backed by real shares held in custody, depend on reliable, consistent price feeds from traditional exchanges.

If Rule 611 is removed, the best-price guarantee that currently unifies pricing across U.S. stock exchanges would disappear. Tokenized stock platforms could face challenges sourcing a single reliable reference price, potentially leading to wider spreads or pricing mismatches between the tokenized product and its underlying equity.

The change could also affect liquidity dynamics. As Markets Media reported, the SEC’s direction has prompted discussion about how tokenized markets might need to adapt their infrastructure. Platforms offering tokenized U.S. stocks would need to decide which venue’s price to reference, or build aggregation systems similar to those used by traditional smart order routers.

It is worth distinguishing between direct and indirect effects. Tokenized stock platforms are not themselves subject to Regulation NMS. However, the downstream changes to price formation and execution quality in traditional markets could alter the economics of maintaining tokenized equity products, particularly for smaller crypto firms already navigating regulatory scrutiny across multiple jurisdictions.

What Traders and Crypto Firms Should Watch Next

The SEC’s proposal will go through a public comment period before any final rule is adopted. The timeline and final shape of the regulation remain uncertain, meaning the effects on tokenized stock products are prospective rather than immediate.

Crypto firms offering tokenized equities should monitor how traditional exchanges respond to the potential rule change. If price fragmentation increases in conventional markets, the cost and complexity of maintaining accurate tokenized stock pricing could rise, particularly during volatile sessions when price dislocations in related markets are already a concern.

Trading venues and issuers in the rapidly evolving crypto-linked financial products space should also watch whether the SEC provides guidance on how rescission would interact with digital asset platforms that reference U.S. equity prices. The proposal’s fact sheet focuses on traditional market structure, leaving open questions about cross-market implications.

Outcomes will depend on the final rule details, the comment period’s results, and whether the SEC addresses tokenized products explicitly or leaves them to existing frameworks.
