Should the SEC Scrap the Order Protection Rule for
Published 6/15/2026, 8:02:38 AM
Direct Answer: The SEC has already proposed rescinding Rule 611 (the Order Protection Rule) and Rule 610(e) as of June 11, 2026, opening a 60-day public comment period. This represents a significant policy shift that could remove the most frequently cited structural barrier to tokenized equities trading via DeFi protocols. Whether it should be scrapped depends on weighing innovation benefits against investor protection and market fragmentation risks — a balance the final rulemaking process will determine.
Current Status of Rule 611
The SEC formally proposed rescinding Rule 611 and Rule 610(e) on June 11, 2026, as part of Project Crypto (launched August 2025). The proposal opens a 60-day public comment period, with final rule adoption projected for Q1 2027. [Source: https://www.sec.gov/news/press-release/2026-54]
| Rule | Core Function | Status |
|---|---|---|
| Rule 611 (Order Protection) | Prohibits trade-throughs — executing orders at prices worse than NBBO | Proposed rescission |
| Rule 610(e) | Prevents locked/crossed quotations across venues | Proposed rescission |
Why Rule 611 Blocks Tokenized Equities in DeFi
Rule 611 is structurally incompatible with AMM-based trading for technical reasons:
| Issue | Impact |
|---|---|
| No ISO Routing | AMMs cannot route intermarket sweep orders |
| No SIP Integration | AMMs cannot ingest SIP data with latency guarantees |
| No Trade Halting | Smart contracts cannot halt swaps when better quotes exist |
| Continuous Violations | "Any pool in a tokenized NMS stock would commit trade-throughs constantly and arguably be an illegal trading center" |
| NBBO Drift | AMM prices drift continuously, routinely locking or crossing the displayed NBBO |

Arguments FOR Rescinding Rule 611
| Argument | Detail |
|---|---|
| Regulatory unlock | Removes the single biggest legal obstacle between DeFi and US equity markets |
| Principles-based best execution | Proposed replacement: broker-dealers must demonstrate policies "reasonably designed to achieve best execution for clients overall" |
| Market structure modernization | Current rules designed for centralized exchanges, not decentralized blockchain protocols |
| Settlement innovation | Enables atomic/DvP settlement of tokenized securities |
| Competition | 17 national exchanges vs. 4 pre-NMS; off-exchange volume exceeds 50%; no exchange held more than 20% share in H1 2025 |
Christopher Perkins, CEO of 250 Digital Asset Management, called it a "whole new ballgame" for DeFi, noting that a regulatory pathway was needed more than a technological breakthrough. [Source: https://finance.yahoo.com/news/galaxy-digital-analysis]
Arguments AGAINST Rescinding Rule 611
| Concern | Detail |
|---|---|
| Investor protection | Current framework provides critical protections through trading on registered platforms with FINRA oversight |
| Market fragmentation | Could lead to "decreased liquidity by fracturing into distinct pools not readily accessible by all parties" |
| Pricing transparency | Material pricing changes could occur outside consolidated tape |
| Institutional access | Retirement plans and institutional investors may lose access to certain liquidity pools |
| Regulatory arbitrage | Trading platforms might migrate NMS activity to DLT platforms to avoid Reg NMS protections |
| MEV extraction | Blockchain trading exposed to sandwich attacks and maximal extractable value (MEV) extraction |
SIFMA's Position: Welcomed review but warned of interconnected market structure pieces, urging the SEC to study effects on investors, execution quality, and tokenized securities through an "open and transparent process which allows for public notice and comment, oversight, and broad industry engagement."

Key Industry Positions
| Entity | Position |
|---|---|
| Galaxy Digital (Alex Thorn) | Most significant regulatory unlock for tokenized equities |
| 250 Digital Asset Management (Christopher Perkins) | "Whole new ballgame" for DeFi |
| SIFMA | Welcomed review but warned of interconnected market structure pieces |
| SEC Staff (December 2025) | No relaxation of Reg NMS requirements for tokenized securities should occur |
Unresolved Questions & Gaps
- c1 (Unresolved): The task confirms Rule 611 historically applied to NMS securities and that the SEC has proposed rescinding it, but does not definitively establish the current applicability status as contested or uncertain for tokenized equities specifically.
- c3 (Unresolved): Arguments against rescission are documented (market fragmentation, investor protection, regulatory arbitrage, MEV extraction), but the specific concern labeled "systemic stability" in the evidence ledger was not explicitly identified in the source materials.
- c4 (Unresolved): The evidence ledger references DTCC Project Ion as a tokenized securities pilot providing context, but no information about this specific initiative was found in the research outputs. [Note: not independently confirmed]
Remaining Regulatory Hurdles (Even if Rescinded)
Even if Rules 611 and 610(e) are eliminated, tokenized stocks face substantial additional requirements:
- Exchange/ATS Registration Questions
- Clearance and Settlement infrastructure
- Regulation SHO (short sale requirements)
- Regulation SCI (systems compliance)
- Market Access Rule (SEA Rule 15c3-5)
- Consolidated Audit Trail (CAT) Reporting — Rule 613
- FINRA Requirements for broker-dealer membership
Timeline
| Milestone | Expected Date |
|---|---|
| Comment period closes | ~August 2026 |
| Final rule adoption | Q1 2027 |
| Pilot exemptions possible | Before formal repeal |
Conclusion
The SEC's proposal to rescind Rule 611 represents a significant policy shift that could remove a fundamental barrier to tokenized equities trading via DeFi protocols. The arguments for rescission center on enabling innovation and modernizing market structure for blockchain-based trading. The arguments against center on investor protection, market fragmentation risk, and the interconnected nature of regulatory safeguards. The 60-day comment period will be critical in shaping final rulemaking, and even if rescinded, substantial regulatory hurdles remain before tokenized equities can trade freely on DeFi infrastructure.
Suggested Next Steps:
- Monitor the comment period — Submit or track public comments on the SEC's proposal (closes ~August 2026) to gauge industry sentiment and identify specific investor protection safeguards being proposed.
- Assess remaining regulatory gaps — Even if Rule 611 is rescinded, evaluate which of the seven remaining regulatory hurdles (ATS registration, CAT reporting, Regulation SHO) pose the greatest practical barriers to DeFi-based tokenized equity trading.
