Catenaa, Saturday, June 20, 2026- A seemingly technical proposal from the US Securities and Exchange Commission could fundamentally reshape the future of blockchain finance, with analysts now describing it as the most consequential regulatory development for the American cryptocurrency industry this year.
The SEC’s proposal to repeal two cornerstone provisions of Regulation National Market System (NMS) has attracted growing attention from digital asset companies, tokenization platforms and decentralized finance developers who believe the move could unlock a new era of blockchain-based securities trading.
Benchmark Equity Research said the proposal may remove one of the biggest legal barriers preventing tokenized stocks and decentralized exchanges from operating efficiently within the US financial system.
If adopted, the changes could accelerate the migration of traditional financial assets onto public blockchain networks.
The SEC is proposing to eliminate Rule 611 and Rule 610(e), two regulations that have shaped US stock trading since 2005.
Rule 611, commonly known as the Order Protection Rule, requires trading venues to execute stock transactions at the best available quoted price across all markets.
Rule 610(e) prevents so-called locked and crossed markets by regulating how trading venues display prices.
Together, the rules form the foundation of America’s modern equity market structure.
The SEC argues that the framework has become increasingly complex and costly while limiting innovation.
The agency wants to create a simpler system that encourages competition and technological advancement.
For traditional stock exchanges, the proposal is largely a market structure issue.
For blockchain companies, it could be transformative.
Decentralized exchanges operate differently from conventional trading venues.
Instead of routing orders through centralized order books, many rely on automated market makers, or AMMs, which determine prices through algorithmic liquidity pools.
Those systems do not reference the National Best Bid and Offer structure required under current regulations.
As a result, tokenized stock trading on decentralized platforms has faced significant legal uncertainty.
Removing those restrictions could allow blockchain-based trading systems to function much more naturally within US markets.
The proposal arrives at a time when tokenized securities are becoming one of the fastest-growing sectors in finance.
Banks, asset managers and fintech companies are increasingly exploring blockchain-based versions of stocks, bonds, funds and real estate.
Tokenization promises faster settlement, lower costs and 24-hour trading access.
Major institutions including BlackRock, JPMorgan, Citi and several global exchanges have already launched tokenization initiatives.
Industry estimates suggest tokenized assets could reach several trillion dollars in value before the end of the decade.
The SEC proposal could significantly accelerate that transition.
Analysts believe several companies are particularly well-positioned to benefit.
Securitize, which provides regulated infrastructure for tokenized securities, is viewed as one of the most direct beneficiaries.
The company already supports major tokenization projects including BlackRock’s tokenized money market fund initiative.
Coinbase could also gain through expanded brokerage, custody and trading opportunities tied to tokenized assets.
Galaxy Digital may benefit through its growing role in digital asset infrastructure and market-making operations.
The broader decentralized finance sector could see substantial opportunities as tokenized securities begin interacting with blockchain liquidity pools.
The proposal does not solve every regulatory issue.
Important questions surrounding custody, settlement, exchange registration and investor protection remain unresolved.
Tokenized stocks may still require new frameworks governing ownership rights, clearing systems and compliance standards.
Industry participants are increasingly looking toward a separate SEC innovation exemption that could address many of these concerns.
Without additional regulatory guidance, some uncertainty will remain.
The significance of the proposal extends beyond cryptocurrency.
The repeal would represent one of the largest structural changes to US equity market regulation in two decades.
Traditional exchanges, brokerages and financial institutions are closely monitoring the process.
Many industry observers believe the proposal reflects a broader recognition that financial markets are evolving toward more programmable, digital and decentralized infrastructure.
Blockchain technology is increasingly moving from the margins of finance toward the core of capital markets.
The SEC has opened a 60-day public comment period before considering next steps.
Benchmark expects a final vote on the proposal could occur during early 2027.
That timeline gives market participants several months to influence the outcome.
If approved, the changes could become one of the most important regulatory catalysts in the history of tokenized finance.
The SEC’s proposal to dismantle key elements of Regulation NMS may appear technical, but its implications could be enormous. By potentially removing long-standing barriers to decentralized trading and tokenized securities, the agency may be laying the foundation for blockchain technology to become fully integrated into US capital markets. For crypto firms, tokenization platforms and traditional financial institutions alike, the proposal could mark the beginning of a new phase in the evolution of digital finance.
Regulation NMS was introduced in 2005 to modernize US stock markets and ensure investors received the best available prices across multiple exchanges. Since then, market structure has become increasingly fragmented and technologically complex. Meanwhile, blockchain technology has enabled new models for trading, settlement and asset ownership that operate differently from traditional financial systems. Tokenized securities have emerged as one of the fastest-growing applications of blockchain technology, attracting interest from major financial institutions. The SEC’s proposal to repeal Rules 611 and 610(e is widely viewed as an attempt to modernize regulations for an increasingly digital financial environment while encouraging innovation in both traditional and blockchain-based markets.
