Three SEC divisions published the first comprehensive staff guidance on tokenized securities on January 28, 2026, setting out exactly what can trade, who can participate, and how federal law applies — before backing the architecture with two approved exchange rule changes and an operational pilot at the country's central securities depository.

What the framework covers

The January 28 joint statement from the SEC's Division of Corporation Finance, Division of Investment Management, and Division of Trading and Markets defines a tokenized security as "a financial instrument enumerated in the definition of 'security' under the federal securities laws that is formatted as or represented by a crypto asset, where the record of ownership is maintained in whole or in part on or through one or more crypto networks." The definition is deliberately broad: any instrument that qualifies as a security under the Exchange Act or Securities Act qualifies, regardless of asset type.

The statement draws two principal categories. Issuer-sponsored tokenization covers securities where the issuer or its transfer agent records ownership on-chain; the Divisions state that federal securities laws apply identically regardless of "the format in which a security is issued or the methods by which holders are recorded." Third-party tokenization splits further into custodial models, where an intermediary holds the underlying security or security entitlement and issues a token against it, and synthetic models, where the intermediary creates a token tracking the security's value without conferring any direct ownership interest. Synthetic tokens are treated as distinct instruments — closer to derivatives — and carry different regulatory implications for the issuing entity.

For all models, the statement is unambiguous: the format of recordkeeping does not alter the applicability of the Securities Act, Exchange Act, Investment Company Act, or Investment Advisers Act. Broker-dealers, investment advisers, and fund managers touching tokenized securities operate under the same compliance and registration framework they do today.

The DTC pilot and the exchange rule changes

The operational machinery runs through the Depository Trust Company. On December 11, 2025, the SEC's Division of Trading and Markets issued DTC a no-action letter authorizing a three-year tokenization pilot covering DTC-custodied assets on supported blockchains. The pilot launch is planned for the second half of 2026. DTC must file quarterly reports covering participant lists, shares and dollar value tokenized, average daily transfer volumes, de-tokenization counts, blockchain utilization, and wallet counts. The relief covers SRO rule filing requirements under Section 19(b), Covered Clearing Agency obligations under Rule 17Ad-22(e), and Regulation SCI requirements.

Nasdaq filed SR-NASDAQ-2025-072 on September 8, 2025, and the SEC approved it on March 18, 2026 (Release No. 34-105047). NYSE filed SR-NYSE-2026-17 on April 9, 2026; the SEC granted immediate effectiveness on April 17, 2026 (Release No. 34-105260). Both rule changes adopt essentially identical mechanics, explicitly modeled on each other.

Under the approved rules, DTC Eligible Participants — exchange member organizations cleared by DTC to participate in the pilot — can select a tokenization flag at order entry. The flag instructs DTC to settle the trade in token form rather than book-entry form. Eligible securities — described as Russell 1000 constituents at service launch (plus subsequent additions, notwithstanding removals) and ETFs tracking major indices including the S&P 500 and Nasdaq-100 — trade on the same order book as their traditional counterparts, with the same execution priority. A tokenized share must share the identical CUSIP number, trading symbol, and shareholder rights as its traditional counterpart; instruments that do not meet those conditions are treated as distinct securities, such as ADRs or derivatives.

The NYSE filing makes the structural intent explicit: "The Exchange believes that no significant exemptions or parallel market structure constructs are needed for tokenized securities to trade alongside other securities, and that the markets can accommodate tokenization while continuing to provide the benefits and protections of the national market system."

Who benefits and who is disrupted

DTC is the clearest institutional winner. Clearing and settlement remain within the existing national market system; the on-chain layer sits atop DTC's infrastructure rather than bypassing it. The pilot extends DTC's role into the blockchain stack, not around it.

Nasdaq and NYSE gain first-mover positioning without structural disruption to their matching engines. Tokenized and non-tokenized shares trade on the same book with the same priority rules.

Custodians and prime brokers who are DTC participants can participate at launch; the flag is set at order entry and the tokenization instruction flows through DTC. Non-DTC-eligible firms cannot participate until admitted.

Third-party tokenization platforms — particularly firms that issue tokens referencing securities they do not control — face the more complex regulatory map. The January 28 statement's distinction between custodial and synthetic third-party models determines which regulatory regime applies, and the synthetic model triggers Investment Company Act analysis for the token issuer.

Retail-facing crypto platforms that sought broad exemptive relief to offer tokenized equities outside the national market system got a negative answer. SIFMA's November 2025 comment letter to the SEC Crypto Task Force urged the Commission to reject requests to grant such relief through informal no-action letters rather than a notice-and-comment rulemaking process, arguing that "securities regulatory frameworks must be applied to DeFi markets" and that digital asset securities currently lack the mandated consistency of valuation and transparency found in regulated market infrastructure.

Limits and open questions

The framework's scope is tightly contained. The DTC pilot lasts three years from launch — expected second half of 2026. It covers only securities eligible under the No-Action Letter terms; the initial universe is restricted to Russell 1000 constituents and major-index ETFs. De-tokenization is required in certain corporate action scenarios: DTC's own documents note that a participant "may need to issue a de-tokenization instruction or DTC may need to force conversion of the Tokenized Entitlement into a Book-Entry Entitlement in order to receive a distribution or replacement security or to issue instructions in relation to the corporate action." That carve-out limits the programmability use case the industry had cited as a core benefit.

The January 28 staff statement carries no rulemaking authority. It represents staff views, not Commission action. Commissioner Hester Peirce had framed the underlying approach in July 2025 remarks titled "Enchanting, but Not Magical," emphasizing that tokenization should proceed as "regulated evolution" — a framing the January statement explicitly built on. No formal rulemaking has been proposed to make the current framework durable beyond the pilot window.

SIFMA's December 2025 submission to the Crypto Task Force stated that "markets for digital asset securities currently lack such mandated providers" for consistent asset valuation, and warned that applying exemptive relief before infrastructure standards are established risks reproducing the conditions that preceded modern securities regulation in the 1930s. The industry's principal lobby is not opposed to tokenization; it is opposed to tokenization that bypasses the registered framework, and that distinction is exactly what the DTC pilot structure was designed to respect.
