On January 28, 2026, the SEC's Divisions of Corporation Finance, Investment Management, and Trading and Markets issued a landmark joint statement establishing the definitive taxonomy for tokenized securities under federal law. The statement — the most comprehensive regulatory guidance on securities tokenization issued by any major market regulator globally — confirms that tokenization does not alter the fundamental regulatory treatment of securities. As the SEC statement establishes, securities remain securities regardless of whether they are recorded on a blockchain or traditional book-entry system.

The statement identifies three primary tokenization models: issuer-sponsored tokenized securities (where the issuer directly integrates DLT into its master securityholder file), custodial tokenized securities (where a third party holds the underlying security and issues a representative token), and synthetic tokenized securities (where a third party creates instruments providing economic exposure without conveying ownership rights). Each model carries distinct regulatory implications for registration requirements, disclosure obligations, investor protection, and market conduct rules. The integrated model — where on-chain transfers directly update the official ownership record — receives the most favorable regulatory treatment, while synthetic models may trigger security-based swap regulation and eligible contract participant restrictions.

This taxonomy builds on SEC Chair Paul Atkins' November 2025 "Token Taxonomy" framework and Commissioner Peirce's "Enchanting, but Not Magical" statement from July 2025, establishing that tokenization is a "regulated evolution" rather than a regulatory exception. The practical consequence for market participants is clear: compliant tokenization proceeds through existing regulatory pathways rather than requiring new legislative authority. Registration requirements under the Securities Act and Exchange Act apply to tokenized securities the same as traditional issuances.

The SEC's December 2025 no-action letter to the Depository Trust Company — a subsidiary of DTCC, the central securities depository processing over $300 trillion in annual transactions — represents the most consequential infrastructure development in US securities tokenization. The three-year no-action relief permits DTC to offer tokenization services allowing DTC Participants to elect to have their security entitlements recorded and transferred using distributed ledger technology rather than exclusively through DTC's traditional centralized book-entry ledger. The DTCC Tokenization Services are planned for launch in the second half of 2026.

Under the approved Preliminary Base Version, DTC Participants can register blockchain wallet addresses and receive tokens representing their security entitlements to DTC-custodied assets. Crucially, securities remain registered in the name of Cede & Co. (DTC's nominee), and the tokens themselves are not the securities — they serve as an alternative method for recording and transferring security entitlements on DTC's official books. This preserves the existing indirect holding model under Article 8 of the Uniform Commercial Code while introducing blockchain-based mobility, programmability, and 24/7 operational capability.

The institutional implications are profound. As Deloitte and McKinsey have documented, securities settlement currently involves T+1 delays, reconciliation costs, and counterparty risk that tokenization can structurally reduce. With DTCC at the center, tokenized settlement gains the institutional credibility and scale that previous tokenization attempts — operating outside established clearing infrastructure — could never achieve.

Nasdaq's 2025 regulatory filing requesting SEC approval to trade tokenized securities on its US national securities exchanges represents a potential paradigm shift in market structure. If approved, member firms could tokenize actual listed equities and exchange-traded products, enabling blockchain-based settlement while maintaining the regulatory protections of exchange-traded markets. The filing proposes integrating distributed ledger technology into Nasdaq's existing market infrastructure rather than creating separate tokenized trading venues — a critical distinction that preserves market integrity, surveillance capabilities, and investor protection.

The implications for market microstructure are substantial. Exchange-traded tokenized securities could enable continuous settlement (potentially T+0 or real-time), programmable corporate actions (automated dividend distribution via smart contracts), and atomic settlement (simultaneous exchange of security and payment on-chain). The proposal also addresses fractional ownership — tokenized securities on Nasdaq could theoretically enable sub-share ownership of high-priced equities, expanding retail access without the synthetic exposure concerns identified in the SEC's January 2026 statement.

Market participants evaluating the Nasdaq filing should note that SEC approval remains pending and the timeline is uncertain. However, the filing's significance lies in the signal it sends: the world's largest exchange operator views tokenization not as a niche experiment but as the future operating model for US equity markets. Combined with JP Morgan's JPMD tokenized deposit launch on Coinbase's Base network for institutional 24/7 settlement, the infrastructure layer for tokenized US securities is being built by the incumbent institutions that control market access.

The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, signed into law in July 2025, establishes the regulatory framework for payment stablecoins that will serve as settlement infrastructure for tokenized securities. The Act requires 1:1 reserves backing in cash or short-term Treasuries, monthly third-party attestation, and a bank-like supervisory regime for issuers. Payment stablecoins are explicitly excluded from securities and commodities classification, creating regulatory certainty for their use in securities settlement. The GENIUS Act creates both federal (OCC) and state licensing pathways for stablecoin issuers, with federal oversight required for issuers exceeding $10 billion.

For securities tokenization, the GENIUS Act's most significant provision is the legitimization of bank-issued stablecoins as settlement media. JP Morgan's JPMD, Circle's USDC (subject to GENIUS Act compliance), and bank-issued tokenized deposits can now serve as the payment leg of atomic securities settlement — enabling simultaneous delivery-versus-payment on blockchain. The Act also preserves existing banking authority for financial institutions to issue tokenized deposits, which unlike payment stablecoins can bear interest.

The intersection of GENIUS Act infrastructure with SEC tokenization guidance and DTCC services creates a complete institutional stack: tokenized securities (SEC-regulated) settling against regulated stablecoins or tokenized deposits (GENIUS Act-regulated) through institutional clearing infrastructure (DTCC no-action letter). This convergence — occurring within a 12-month window — is unprecedented in the pace of regulatory infrastructure development for any financial innovation.

Issuer-sponsored tokenized securities receive the most straightforward regulatory treatment under the SEC's taxonomy. In the integrated model, the issuer or its transfer agent integrates DLT into the master securityholder file, so that an on-chain transfer directly effects a transfer of the security on the official ownership record. The SEC clarifies that if the tokenized security carries "substantially similar character" and "substantially similar rights and privileges" to existing securities of the same issuer, it may be treated as the same class for securities law purposes.

The alternative issuer-sponsored model — where the blockchain does not constitute the master securityholder file — maintains authoritative ownership records off-chain, with token transfers serving as notifications that trigger updates to the off-chain record. This model introduces less technological disruption to existing transfer agent infrastructure while still enabling blockchain-based mobility and programmability. Both models require registration under the Securities Act (or qualification for an exemption) and compliance with Exchange Act reporting obligations where applicable. Transfer agents maintaining on-chain records must comply with Exchange Act Section 17A and related SEC rules.

The SEC's January 2026 statement draws a critical regulatory line between custodial and synthetic third-party tokenization models. Custodial tokenized securities — where a third party holds the underlying security and issues a token representing a security entitlement — receive treatment analogous to traditional indirect holdings. The token holder's rights depend on the third party's custody and recordkeeping arrangements, and the third-party custodian assumes obligations as a securities intermediary under UCC Article 8.

Synthetic tokenized securities — where a third party issues instruments providing economic exposure to an underlying security without conveying ownership rights — face substantially more complex regulatory treatment. The SEC identifies two synthetic sub-categories: linked securities (structured notes or exchangeable instruments whose return is tied to a referenced security) and security-based swaps (derivative instruments providing synthetic exposure). Security-based swaps are subject to Exchange Act requirements including eligible contract participant restrictions that effectively limit retail access. The SEC's warning followed OpenAI's public disavowal of tokenized "equity" linked to its shares offered through European platforms.

For institutional market participants, the practical guidance is clear: issuer-sponsored and regulated custodial models represent the compliant pathway for tokenized securities. Synthetic models carry heightened regulatory scrutiny, potential Investment Company Act implications, and the risk that the third-party sponsor may be deemed an investment company.

Tokenized US Treasuries represent the most mature segment of the US securities tokenization market, with over $8.7 billion in on-chain value across institutional products. BlackRock's BUIDL fund leads at $1.87 billion AUM, followed by Franklin Templeton's FOBXX (the first US-registered tokenized fund), Hashnote's USYC, and Ondo Finance's OUSG. These products provide institutional investors with tokenized exposure to short-term US government securities — maintaining a stable NAV while distributing yield of approximately 4.3-5.0% annually.

The competitive landscape is intensifying as traditional asset managers enter. BlackRock's institutional brand positions BUIDL for sovereign wealth and large institutional allocations, while Ondo Finance targets a broader qualified investor base with lower minimums. Franklin Templeton's FOBXX leverages its SEC registration as a '40 Act fund to provide regulatory comfort that pure crypto-native products cannot match. The integration of tokenized treasuries with DeFi lending protocols enables capital-efficient strategies unavailable through traditional money market structures.

DTCC's planned tokenization services will potentially transform this market by enabling tokenized entitlements to actual DTC-custodied Treasury securities — providing institutional custody through the existing clearing infrastructure rather than requiring investors to evaluate novel custodians.

Exchange-traded tokenized equities represent the next frontier for US securities tokenization. Nasdaq's regulatory filing to trade tokenized securities on its national exchanges, combined with the SEC's issuer-sponsored taxonomy, creates a pathway for listed companies to issue tokenized shares that trade on established exchange infrastructure. The proposal preserves existing market surveillance, circuit breakers, and investor protection mechanisms while adding blockchain-based settlement capabilities.

The transition from traditional book-entry equities to tokenized equities could fundamentally alter market microstructure. Real-time settlement eliminates settlement risk and reduces capital requirements for broker-dealers regulated by FINRA for broker-dealers. Programmable corporate actions reduce administrative costs and errors. Fractional share ownership through tokenization could reduce the need for synthetic fractional share programs operated by retail brokerages, where investors hold contractual claims against the broker rather than actual equity interests.

The timeline for exchange-traded tokenized equities remains uncertain pending SEC approval. However, the infrastructure components are being assembled simultaneously: SEC taxonomy guidance (January 2026), DTCC tokenization services (launching H2 2026), GENIUS Act settlement infrastructure (implementation ongoing), and exchange filings (under review). Market participants should prepare for tokenized equities to become available on US exchanges within the 2026-2028 timeframe.

Private securities represent the most active current market for tokenized US securities, operating under existing registration exemptions. Regulation D offerings — the primary vehicle for private placements to accredited investors — have adapted most readily to tokenization, with platforms like Securitize, Polymath, and tZERO facilitating compliant token issuances. The SEC's tokenization taxonomy confirms that Reg D exemptions apply equally to tokenized and traditional securities, provided all other exemption conditions are satisfied.

Regulation A+ (Tier 1 and Tier 2) provides a pathway for tokenized securities offerings to non-accredited investors, with Tier 2 allowing up to $75 million in annual raises with SEC qualification. Regulation Crowdfunding (Reg CF) enables tokenized offerings up to $5 million through registered intermediaries. Each pathway carries specific filing, disclosure, and ongoing reporting requirements that tokenization platforms must integrate into their compliance architecture.

The secondary market for tokenized private securities operates through registered Alternative Trading Systems (ATS) under FINRA oversight. Platforms including tZERO ATS, Securitize Markets, and INX provide regulated secondary trading for tokenized Reg D and Reg A+ securities — addressing the liquidity constraint that historically limited private securities markets.

The SEC's December 2025 broker-dealer custody guidance clarifies how registered broker-dealers can custody crypto asset securities including tokenized securities. The guidance builds on the Customer Protection Rule (Rule 15c3-3) and net capital requirements (Rule 15c3-1), establishing that broker-dealers maintaining custody of tokenized securities must satisfy the same customer protection, segregation, and capital requirements as traditional securities custody. The key challenge is demonstrating "good control location" for tokenized securities.

Compliance officers at broker-dealer firms must evaluate additional requirements: books and records obligations under Exchange Act Rules 17a-3 and 17a-4 extend to on-chain records, FINRA reporting applies, AML obligations under the Bank Secrecy Act encompass blockchain-based transactions, and Reg SHO requirements apply to short sales of tokenized securities. The integration of on-chain and off-chain compliance systems represents a significant operational challenge driving demand for specialized regtech solutions.

For institutional investors, broker-dealer custody through established firms provides the institutional comfort and regulatory protection absent from previous crypto custody arrangements. SIPC protection applies to broker-dealer custody of tokenized securities, providing up to $500,000 in protection per customer — a significant investor protection advantage.

The total addressable market for US securities tokenization encompasses the full spectrum of DTCC-custodied assets — over $300 trillion in annual processing volume. Current institutional projections from McKinsey, BCG, and Ripple estimate the global tokenized RWA market reaching $18.9 trillion by 2033, with the US capturing the dominant share.

The pace of institutional adoption is accelerating: BlackRock, Franklin Templeton, JP Morgan, Goldman Sachs, Nasdaq, DTCC, and dozens of other institutional participants have launched or announced tokenized securities products. An S&P Global survey found that 86% of institutional investors reported digital asset exposure or active allocation intent.

The institutional adoption pattern follows a clear trajectory: infrastructure providers (DTCC, exchanges, transfer agents) are building the rails, asset managers (BlackRock, Franklin Templeton, Ondo) are creating the products, and broker-dealers and custodians are developing access and custody infrastructure. This coordinated build-out across the value chain signals that tokenization is entering the institutional mainstream.

Transfer agents occupy a pivotal role in securities tokenization. The SEC's taxonomy confirms that issuers or their transfer agents can maintain master securityholder files on blockchain. Securitize's role as transfer agent for BlackRock's BUIDL demonstrates the operational model: maintaining the on-chain registry that constitutes the official ownership record while ensuring compliance with SEC transfer agent regulations including recordkeeping, processing, and safeguarding obligations under Exchange Act Rules 17Ad-1 through 17Ad-22.

Traditional transfer agents — Computershare, Equiniti, American Stock Transfer — are evaluating blockchain integration to maintain market relevance as issuers increasingly demand tokenization capability. These obligations translate to blockchain environments through requirements for transaction finality guarantees, backup and recovery procedures for on-chain records, and reconciliation protocols between on-chain and off-chain ownership data.

The SEC has signaled development of an "innovation exemption" framework allowing companies to test novel tokenization models under principles-based safeguards rather than full compliance from day one. Discussed at the joint SEC-CFTC event on January 29, 2026, this sandbox reflects recognition that certain innovations may require temporary regulatory accommodation. The SEC has already demonstrated this approach through individual no-action letters, including the DTCC letter and relief to Fuse Crypto Limited and DoubleZero.

The expected sandbox would formalize a process that has operated informally through SEC FinHub consultations. Commissioner Peirce's long-advocated "Token Safe Harbor" concept has influenced the SEC's increasingly accommodative approach to compliant tokenization innovation.

The CFTC's December 2025 guidance permits futures commission merchants (FCMs) and derivatives clearing organizations to accept tokenized collateral, including tokenized US Treasuries and payment stablecoins, for margin requirements. This enables institutional participants to use tokenized treasury positions as margin for derivatives trading, creating capital efficiency that incentivizes adoption. The guidance was issued through Staff Letters 25-39 and 25-40.

The joint SEC-CFTC event addressed harmonizing oversight of digital asset markets, acknowledging that certain tokenized instruments may fall under both agencies' jurisdiction. Security-based swaps require coordinated oversight. The CFTC's "Crypto Sprint" initiative has accelerated regulatory clarity across derivatives markets, including allowing spot digital assets to trade on registered designated contract markets.

AML/KYC compliance for tokenized securities draws on the existing Bank Secrecy Act framework, FinCEN regulations, and OFAC sanctions compliance requirements. Broker-dealers must maintain customer identification programs (CIP), suspicious activity reporting (SAR), and currency transaction reporting (CTR) requirements identical to traditional securities. On-chain analytics platforms (Chainalysis, Elliptic, TRM Labs) provide transaction monitoring that complements traditional compliance systems.

The Travel Rule applies to tokenized securities transfers between financial institutions. For private securities under Reg D, transfer restrictions are enforced through smart contract logic that verifies accreditation status before permitting secondary transfers — creating a compliance layer operating automatically at the protocol level.

Institutional tokenization requires blockchain infrastructure meeting specific requirements: transaction finality, privacy capability, regulatory compliance tools, operational resilience, and enterprise support. Ethereum remains the dominant chain for tokenized securities (BlackRock BUIDL, most Securitize issuances). Coinbase's Base network hosts JP Morgan's JPMD. Avalanche's institutional subnet architecture enables permissioned environments with compliance controls.

DTCC's tokenization services will operate on approved blockchains meeting institutional criteria: low latency, acceptable transaction costs, privacy capabilities, and operational resilience standards. For issuers, the evaluation framework should prioritize: transaction finality time, regulatory compliance tooling (KYC/AML integration, transfer restrictions), smart contract audit ecosystem, institutional custody support, and long-term network viability.

The IRS treatment follows the principle that tokenization does not alter the fundamental character of the underlying instrument. Tokenized equities are taxed as equities (capital gains rates, dividend treatment), tokenized bonds as debt instruments (ordinary income on interest), and tokenized fund interests follow existing fund taxation rules. The GENIUS Act preserves Treasury Department authority to issue guidance on stablecoin tax classification.

Practical compliance challenges include: cost basis tracking across on-chain transfers, wash sale rule application to blockchain-traded securities, constructive sale rules for offsetting positions, and Form 1099-B reporting obligations. The IRS's crypto reporting framework (Form 1099-DA) intersects with securities reporting requirements, creating complexity that specialized tax technology is being developed to address.

Real estate tokenization in the US operates primarily through securities exemptions — Reg D 506(b) and 506(c) for accredited investors, Reg A+ for broader distribution, and Reg CF for smaller offerings. The tokenized interest typically represents membership units in an LLC or LP that holds the property. The SEC's taxonomy confirms these interests, when tokenized, remain securities subject to the same exemption requirements as traditional private securities.

The institutional opportunity is substantial. The US commercial real estate market exceeds $20 trillion, with the institutional-grade segment representing over $5 trillion. Tokenization enables fractional institutional participation in trophy assets previously requiring $10-50 million minimum commitments. Platforms like RealT, Republic Real Estate, and institutional offerings through Securitize have demonstrated the operational model. The integration of CFA Institute-standard valuation with on-chain NAV reporting creates the transparency institutional allocators require.

Tokenized securities must comply with state securities laws (Blue Sky laws) in addition to federal requirements. NSMIA preempts state registration for "covered securities" including Reg D 506 offerings but does not preempt state anti-fraud provisions or notice filing requirements. For Reg D offerings, issuers must file Form D with the SEC and submit state notice filings. Reg A+ Tier 2 offerings are exempt from state registration but subject to notice filing.

The tokenized nature does not alter Blue Sky obligations but introduces practical complexity: blockchain-based distribution may reach investors across all 50 states simultaneously, requiring comprehensive state filing programs. State money transmitter licensing may also apply to platforms facilitating tokenized securities transactions, depending on how operations are characterized under state law.

The SEC's January 2026 statement specifically addresses Investment Company Act implications. A third party that holds pools of securities and issues tokens representing interests may be deemed an investment company under Section 3(a) of the 1940 Act, requiring registration, diversification compliance, leverage limitations, and board governance. This classification risk applies to custodial tokenization models where the third party pools securities from multiple issuers.

Exemptions — including Section 3(c)(1) (100-investor limit), Section 3(c)(7) (qualified purchaser funds), and Section 3(c)(5)(C) (real estate companies) — may be available depending on structure. However, blockchain-based transferability could undermine the "non-public" requirement of Section 3(c)(1) if tokens are freely transferable to more than 100 holders. Platform operators must carefully structure transfer restrictions to maintain exemption eligibility.

The US approach — applying existing securities laws rather than creating bespoke tokenization legislation — contrasts with the EU's MiCA framework and DLT Pilot Regime. The US model's advantage is speed of implementation (no new legislation required) and certainty (established judicial precedent). For cross-border allocators, the US combination of market depth, regulatory clarity, and institutional infrastructure creates the most compelling market for tokenized securities. The ESMA and SEC are in dialogue on cross-border recognition frameworks.

Institutional investors must assess risks across four dimensions: regulatory risk (SEC policy evolution, enforcement actions, potential classification changes), technology risk (smart contract vulnerabilities, blockchain network disruptions, key management failures), market risk (secondary market liquidity, price discovery efficiency, settlement finality), and operational risk (custody infrastructure reliability, compliance system integration, interoperability between on-chain and off-chain systems).

The most material near-term risk is regulatory evolution — the SEC's January 2026 taxonomy is staff guidance, not a Commission rule, and carries the caveat that it "does not create new or additional obligations." A change in SEC leadership could alter the regulatory treatment of specific structures. Technology risk is mitigated by the institutional infrastructure approach (DTCC, Nasdaq, established custodians) but remains relevant for smaller platforms. Market risk centers on secondary liquidity — tokenized securities are only as liquid as the trading venues supporting them.

The institutional tokenization roadmap follows three horizons. In 2026, foundational infrastructure launches: DTCC tokenization services go live (H2), tokenized treasury products continue scaling toward $20-30 billion, GENIUS Act implementation provides regulated stablecoin settlement, and the SEC processes exchange filings. In 2027, exchange-traded tokenized securities potentially become available, broker-dealer custody matures, and institutional allocation moves from pilot to strategic. By 2028, tokenized securities achieve mainstream institutional adoption — with 10-20% of new issuances in certain asset classes using tokenized formats.

The base case — supported by institutional momentum, regulatory trajectory, and infrastructure investment — points to securities tokenization becoming a standard feature of US capital markets by end of decade. Catalysts include continued favorable SEC posture, successful DTCC operation, exchange approval, and institutional demand. Risk factors include SEC leadership changes, major technology failures, adverse court decisions, and macroeconomic conditions reducing appetite for innovation.
