SEC — Digital Assets Division and the US Tokenization Regulatory Framework

Regulator — Every tokenized security issued in the United States operates within a regulatory framework shaped by the Securities and Exchange Commission. The SEC’s authority derives from the Securities Act of 1933 and the Securities Exchange Act of 1934 — statutes written before digital computing existed, interpreted and applied to blockchain-based assets through a combination of no-action letters, enforcement actions, staff bulletins, and, increasingly, formal rulemaking. The SEC’s institutional posture toward digital assets shifted meaningfully between 2022 and 2026, creating a regulatory environment that is more navigable for institutional tokenization than at any prior point in the technology’s history — while leaving significant jurisdictional and definitional questions unresolved.

Overview

The Securities and Exchange Commission is an independent regulatory agency of the US federal government, created by the Securities Exchange Act of 1934. Its mandate encompasses investor protection, the maintenance of fair, orderly, and efficient markets, and the facilitation of capital formation. The SEC oversees securities exchanges, broker-dealers, investment advisers, investment companies, and transfer agents — touching virtually every participant in the US financial system that deals in securities.

The SEC’s primary regulatory jurisdiction over digital assets derives from the Howey test — the Supreme Court’s 1946 framework for defining an “investment contract” (and thus a security): an investment of money in a common enterprise with an expectation of profits from the efforts of others. Most tokenized real-world assets — tokenized funds, tokenized equity, tokenized debt — are clearly securities under Howey; the regulatory questions in tokenization arise not from definitional ambiguity but from how existing regulatory frameworks (registration requirements, transfer agent rules, ATS regulations) apply to blockchain-based instruments.

The Office of Strategic Hub for Innovation and Financial Technology (FinHub) serves as the SEC’s primary engagement point for the digital asset industry. FinHub’s role is to provide guidance, engage with industry participants developing novel products, and inform the commission’s rulemaking on digital asset questions. Companies seeking no-action letters (informal SEC guidance that a particular activity will not result in enforcement) or clarification on the regulatory status of proposed products route those requests through FinHub.

The Crypto Task Force, established in 2025 under new SEC Chair Paul Atkins (who replaced Gary Gensler in January 2025), represents the most significant institutional posture shift in the SEC’s approach to digital assets. Under Gensler, the SEC pursued aggressive enforcement — suing Coinbase, Kraken, Binance, and Ripple; rejecting spot Bitcoin ETF applications repeatedly; and issuing SAB 121 (which would have made bank crypto custody economically prohibitive). The leadership transition brought a mandate to engage with industry stakeholders, clarify applicable rules, and establish formal policy rather than enforcement-led regulation.

SAB 121 — Staff Accounting Bulletin 121, issued in March 2022 — was one of the most consequential and controversial SEC actions in the digital asset context. It required companies that custody crypto assets on behalf of clients to record those assets as both an asset and a corresponding liability on their balance sheets — effectively requiring custodians to hold capital against the full value of client crypto positions. For regulated banks, this capital requirement would have made crypto custody prohibitively expensive. The SEC’s reversal of SAB 121 in early 2025 under new leadership removed this obstacle, clearing the path for major banks to offer crypto custody services.

The spot Bitcoin ETF approval in January 2024 — granted after years of rejections — was the most significant single SEC action for institutional digital asset adoption. The approval allowed BlackRock, Fidelity, Invesco, and eight other asset managers to launch registered funds tracking Bitcoin prices, opening institutional and retail investment to Bitcoin through conventional brokerage accounts. The Bitcoin ETFs collectively accumulated over $100 billion in AUM within their first year.

As of February 2026, no company has obtained SEC registration of a public digital security token offering through the standard S-1 registration process. All institutional tokenized securities operate under exemptions — primarily Regulation D (private placement to accredited investors) and Regulation S (offshore offerings). The one exception is INX Limited, which completed a full SEC-registered offering of digital security tokens — but this required an 18-month review process and remains an isolated precedent rather than an established pipeline.

Key Metrics

Tokenization Activity

The SEC’s regulatory framework for tokenized securities has evolved through a combination of formal rulemaking, staff guidance, and enforcement precedent. The current landscape for institutional tokenized assets is defined by four primary legal structures:

Regulation D (Rule 506(b) and 506(c)) provides the most commonly used exemption for tokenized fund offerings like BUIDL, SCOPE, and the KKR/Apollo/Hamilton Lane products. Rule 506(b) allows unlimited fundraising from accredited investors without general solicitation; Rule 506(c) allows general solicitation but requires verification of accredited investor status. Both exemptions prohibit resale within six months to a year (creating the secondary market liquidity constraints that platforms like Securitize Markets and tZERO work within).

The Investment Company Act of 1940 governs registered funds like FOBXX (Franklin Templeton) and BUIDL’s fund wrapper. The SEC’s willingness to approve blockchain-based recordkeeping for 1940 Act funds, and to grant exceptions to SAB 121 for bank custody of digital assets, represents a deliberate policy choice to accommodate blockchain innovation within the existing investment company regulatory framework rather than creating a separate digital asset fund category.

Proposed rules on Alternative Trading System operations — which would require current blockchain-based secondary markets to register as exchanges rather than ATSs if they meet volume and activity thresholds — represent a pending regulatory risk for platforms like Securitize Markets and tZERO. The Crypto Task Force’s engagement with this issue as of 2025-2026 has created regulatory uncertainty that platforms are navigating carefully.

Investment Relevance

The SEC’s regulatory posture is the single most important variable for the pace of US tokenized asset market development. A more permissive regulatory environment — clear guidance on token classification, ATS exemptions for digital securities, streamlined registration processes — would dramatically accelerate institutional issuance and investment. Regulatory tightening or adverse enforcement actions can equally constrain the market.

Investors in tokenization-exposed equities (Coinbase, BlackRock, major custodians) and in tokenized asset products (BUIDL, OUSG) should monitor SEC rulemaking, Crypto Task Force communications, and enforcement action patterns as leading indicators of market trajectory.
