SEC Rule 611 Draft Repeal Could Remove Key Barrier for Tokenized US Stocks
The US Securities and Exchange Commission (SEC) has proposed scrapping Rule 611 and Rule 610(e) in its national market system regulations. Rule 611 blocks “trade-throughs,” while Rule 610(e) limits exchanges from showing bids that match or beat better available prices elsewhere.
Galaxy’s head of research Alex Thorn said the SEC Rule 611 repeal is a “major unlock” for tokenized US stocks trading on decentralized platforms, especially DeFi. He argued that automated market makers (AMMs) cannot reliably comply with trade-through protections because they execute orders against the pool’s current price, which continuously changes. Under today’s framework, any tokenized stock pool governed by these rules could trigger constant trade-throughs and risk being treated as an illegal trading venue.
Thorn suggested the SEC may replace the rules with a “best execution” framework, which could allow AMMs to operate under more flexible compliance standards. The SEC opened a 60-day comment period, after which it will review feedback and may revise the proposal.
Trader relevance: if SEC Rule 611 is ultimately repealed or softened into a best-execution model, it could improve the legal viability of DeFi-style liquidity for tokenized equities. That may support sentiment around tokenization and AMM-adjacent DeFi assets, though timing and final rule wording remain uncertain.
Neutral
The news is constructive for the tokenized equities thesis, but it’s not a final policy change. The SEC’s proposed removal of Rule 611 (and Rule 610(e)) directly targets the trade-through and quote-display constraints that Alex Thorn argues AMMs can’t follow. If the SEC moves from strict price-protection rules to a “best execution” framework, decentralized or AMM-based liquidity for tokenized US stocks would likely face fewer legal frictions—this is a clear medium-term positive for the sector.
However, traders should account for uncertainty: the proposal is under a 60-day comment period, the SEC may revise it, and market structure questions raised by exchanges have already caused postponements in related efforts. Historically, when US regulators shift from “hard” trading rules toward more flexible execution standards, the market often reacts with initial optimism, but sustained repricing tends to wait for final approval and implementable operational details.
Short term, expect mostly narrative-driven sentiment in tokenization/DeFi proxies rather than immediate, broad-market impact. Long term, if the final rule package enables AMMs, it could support deeper liquidity and more credible on-chain access to US equities—potentially boosting volumes and attracting more participants. But without final confirmation, the net effect is best categorized as neutral.
