Tokenization changes how a bond, fund interest, or property-linked claim is recorded and transferred; it does not itself change the claim’s legal character. The question is when a token falls within securities, financial-instrument, or collective-investment definitions, and which ownership, custody, trading, and settlement duties then apply.
Summary
- Comparative. Regulators classify the enforceable rights and economic function, not the token label or ledger. A bond, share, or fund unit remains that instrument when represented on distributed ledger technology. A third-party wrapper may create a second claim with separate counterparty and insolvency risk.
- Bonds. A tokenized bond is ordinarily a security or financial instrument because the reviewed laws capture bonds through express debt categories or general securities definitions. In the United States, an atypical note also requires the family-resemblance analysis in Reves v. Ernst & Young, 494 U.S. 56, 63–67 (1990).
- Funds. A token representing an existing fund unit remains a fund interest. A bespoke property arrangement can also become a collective investment vehicle when investors supply capital, lack day-to-day control, and depend on pooled or centrally managed returns.
- Property. A direct claim to occupy or own identified land differs from an SPV share, debt claim, rental-income participation, or pooled appreciation right. The latter forms usually fall within securities or collective-investment law. A token cannot transfer land title unless the situs law recognizes that transfer method.
- Custody. Control of a private key proves operational power over a ledger entry. It does not, without more, prove legal title, a protected securities entitlement, or exclusion from the custodian’s insolvency estate. The controlling documents must identify the authoritative ownership record, segregation method, transfer process, and loss-allocation rule.
- Settlement. Blockchain confirmation is not necessarily legal settlement finality. The system must define matching, irrevocability, cash-leg discharge, delivery versus payment, reversals, forks, failed transfers, and the point when the buyer acquires enforceable rights.
- Market access. Security classification activates public-offer, registration or prospectus, intermediary-licensing, venue, custody, recordkeeping, and market-conduct duties. The EU DLT Pilot Regime and UK Digital Securities Sandbox provide targeted infrastructure modifications; neither changes the security status of an instrument.
- Current law. The United States’ CLARITY Act remained pending on August 2, 2026. The United Kingdom’s new cryptoasset activity regime does not reach full commencement until October 25, 2027. Neither displaces the current rules analyzed here.
- Practice. Counsel should classify the legal right before reviewing the technology. The next steps are to test the issuer and wrapper, identify the controlling register, map each regulated activity, obtain situs-law advice for land, and test custody and settlement through insolvency and operational-failure scenarios.
Legal rights control the classification
Tokenization supplies a recording and transfer mechanism. The legal object may be a share, debt claim, fund unit, direct property right, contractual receipt, derivative, or no enforceable asset right at all. Classification therefore starts with the instrument terms, issuer obligations, holder remedies, and governing law.
The first question is whether the right is an expressly named security. The reviewed laws expressly capture shares, bonds, debt instruments, and fund units. A distributed ledger does not remove those rights from the statutory list. MiFID II states this directly by including instruments issued through distributed ledger technology within “financial instruments.” Directive 2014/65/EU, art. 4(1)(15), Annex I § C. The SEC’s current Commission interpretation reaches the same result for a financial instrument represented on a crypto network. Application of the Federal Securities Laws to Certain Types of Crypto Assets and Certain Transactions Involving Crypto Assets, Securities Act Release No. 33-11412, Exchange Act Release No. 34-105020, 91 Fed. Reg. 13714, 13721 (Mar. 23, 2026).
The second question addresses a right outside the express list. The United States applies the investment-contract test to an investment of money in a common enterprise with a reasonable expectation of profits from others’ efforts. SEC v. W.J. Howey Co., 328 U.S. 293, 298–300 (1946). The European Union asks whether the token is a negotiable transferable security, a unit in a collective investment undertaking, or another Annex I instrument. Directive 2014/65/EU, art. 4(1)(44), Annex I § C. The United Kingdom, Switzerland, and Hong Kong apply their own specified-investment, collective-investment, or securities definitions.
The third question separates the underlying asset from the token structure. Land, artwork, and a non-security cryptoasset can support a securities transaction without becoming securities themselves. Howey treated land-sale and service contracts together as investment contracts. The SEC’s 2026 interpretation likewise distinguishes a non-security asset from a transaction or wrapper that creates a security. Release Nos. 33-11412 and 34-105020, 91 Fed. Reg. at 13716–17, 13721.
The fourth question distinguishes issuer-native records from third-party wrappers. An issuer may make the ledger entry the recognized record of its own debt or equity. A third party may instead hold the original instrument and issue a token linked to it. The wrapper holder may then own a claim against the third party rather than the original instrument. The token terms, custody agreement, account structure, perfection rules, and insolvency law decide that result.
This distinction can produce two regulated instruments. The underlying share or bond remains a security. The wrapper may also be a receipt, participation, derivative, investment-company interest, or other security. Release Nos. 33-11412 and 34-105020, 91 Fed. Reg. at 13721. Counsel must analyze both layers and cannot assume one-for-one backing gives the wrapper holder direct ownership.
Tokenized bonds
A tokenized bond ordinarily remains a security in every reviewed jurisdiction. The conclusion follows from the express statutory categories, not from a residual technology test. The Securities Act includes notes and bonds. 15 U.S.C. § 77b(a)(1). MiFID II includes transferable debt securities. Directive 2014/65/EU, art. 4(1)(44), Annex I § C(1). The UK Regulated Activities Order includes bonds and other instruments creating or acknowledging indebtedness. Financial Services and Markets Act 2000 (Regulated Activities) Order 2001, S.I. 2001/544, art. 77. Under Swiss FinMIA, a standardized, mass-tradable ledger-based bond is a security and may qualify as a DLT security. Financial Market Infrastructure Act, SR 958.1, art. 2(b), (bbis). Hong Kong’s Securities and Futures Ordinance includes debentures, loan stocks, funds, bonds, and notes. Securities and Futures Ordinance, Cap. 571, sch. 1, pt. 1.
United States law requires an added inquiry for an instrument called a note. Reves presumes that a note is a security, subject to resemblance to judicially recognized non-security note categories. The court examines the parties’ motivations, the distribution plan, public expectations, and another risk-reducing regime. Reves, 494 U.S. at 63–67. A conventional investment bond will normally satisfy the securities characterization. A short-term commercial payment instrument may not.
The legal design still matters after classification. An issuer-native token can evidence the bond itself if corporate, contract, and recordkeeping law recognize the ledger. A depositary token may instead represent a beneficial claim against an intermediary holding the bond. A synthetic token may promise payments by reference to the bond without conveying any interest in it. Each structure changes the obligor, voting or consent rights, enforcement route, set-off exposure, and insolvency outcome.
Security status also attaches duties beyond issuance. A public offer may need registration, a prospectus, or an exemption. Dealers, advisers, trading venues, transfer agents, depositaries, clearing systems, and custodians may need permission for their functions. A smart contract does not absorb those legal roles merely because it automates transfers or payments.
Tokenized funds and pooled property
A token representing an existing fund unit remains the same fund interest. The token may become the unit-holder register or a parallel record, but it does not remove the scheme’s valuation, redemption, disclosure, management, or depositary duties. MiFID II expressly lists units in collective investment undertakings. Directive 2014/65/EU, Annex I § C(3). The UK Regulated Activities Order lists units in a collective investment scheme. S.I. 2001/544, art. 81. Hong Kong’s securities definition includes interests in collective investment schemes. Securities and Futures Ordinance, Cap. 571, sch. 1, pt. 1. Switzerland applies the Collective Investment Schemes Act to collectively contributed assets managed for investors’ account. Collective Investment Schemes Act, SR 951.31, art. 7.
A bespoke token can create a fund-like arrangement even without a conventional fund label. The central factors are pooled capital or returns, management as a whole, a defined investment policy, investor dependence on a manager, and the absence of day-to-day control. Those factors place many fractional property programs inside collective-investment rules.
The European Union’s ESMA Guidelines identify multiple-investor capital raising, a defined investment policy, and pooled return as core indicators of a collective investment undertaking. Diversification and redemption frequency do not decide the issue. ESMA, Guidelines on the Conditions and Criteria for the Qualification of Crypto-assets as Financial Instruments, ESMA75453128700-1323, paras. 37–43 (Mar. 19, 2025) (nonbinding supervisory guidelines).
The United Kingdom’s statutory test reaches arrangements concerning property when participants lack day-to-day control and the contributions or returns are pooled, or the property is managed as a whole. Financial Services and Markets Act 2000, § 235. Hong Kong’s collective-investment definition follows the same basic structure. Securities and Futures Ordinance, Cap. 571, sch. 1, pt. 1. Swiss law asks whether investors contribute assets for collective investment and another person manages those assets for their account. Collective Investment Schemes Act, art. 7.
The United States reaches pooled structures through several routes. A fund issuer may be an investment company under 15 U.S.C. § 80a-3(a). An interest in a pooled enterprise can also be an investment contract under Howey. Traditional stock or debt issued by a property-owning vehicle falls within the named categories. The analysis must identify the actual instrument before choosing the test.
United Kingdom practice now confirms that a distributed ledger can serve as an authorized fund’s unit-holder register if the responsible firm maintains a complete and current record and can amend it. FCA Policy Statement PS26/7; FCA Instrument 2026/24; COLL 6.4.10G and COLL 6 Annex 4. That permission changes the record medium. It does not remove the authorized fund manager’s or depositary’s duties.
Direct and indirect property interests
A property-linked token presents the sharpest boundary issue because “property exposure” can describe different legal objects. Counsel must separate direct land title, a right to use identified premises, equity in a property-owning company, debt secured on land, a contractual share of rent, and an interest in a managed pool.
A direct title or occupancy right is not automatically a security. United Housing Foundation, Inc. v. Forman treated cooperative shares purchased to obtain housing as non-securities because the economic substance was consumption rather than investment. 421 U.S. 837, 848–53 (1975). That result does not protect a passive return product. Howey held that land interests paired with centralized cultivation and profit sharing formed investment contracts. 328 U.S. at 299–300.
The same distinction appears elsewhere. MiCA excludes unique and non-fungible cryptoassets from its scope, and its recitals mention tokens representing unique real estate. Regulation (EU) 2023/1114, art. 2(3), recitals 10–11. That exclusion is not a securities exemption. Fractional parts, large series, and instruments with financial characteristics may be fungible or may qualify as MiFID II financial instruments. MiCA then excludes them because MiFID II applies. Regulation (EU) 2023/1114, art. 2(4)(a).
ESMA’s nonbinding 2025 Guidelines apply substance over form. A token can qualify as a transferable security when it belongs to a negotiable class and carries rights comparable to shares, bonds, or other securities. A pooled property arrangement can qualify as a collective investment undertaking. A unique title credential with no pooled or investment claim may fall outside those categories, subject to national property law. ESMA75453128700-1323, paras. 11–15, 25–32, 65–72.
UK law reaches indirect property structures through the Regulated Activities Order and section 235 of FSMA. An SPV share is a specified investment under article 76. A property note falls under article 77. Rights or interests in specified investments can fall under article 89. A pooled, centrally managed property arrangement can be a collective investment scheme under section 235 even when the token is not called a unit.
Swiss law permits ledger-based securities under Code of Obligations article 973d when the parties agree to registration in a qualifying securities ledger and the right can be asserted and transferred only through that ledger. That rule does not replace land law. Acquisition of Swiss immovable property generally requires entry in the land register. Swiss Civil Code, SR 210, art. 656. A token transfer alone therefore cannot substitute for the land-register act needed to acquire direct ownership.
Hong Kong’s SFC draws the same functional line. Its 2023 circular treats traditional bonds and funds using distributed ledger technology as tokenized securities. It separately identifies fractional interests in land or profit-sharing arrangements that amount to a collective investment scheme. SFC Circular 23EC52, paras. 5–7. Direct land-title effect still depends on Hong Kong property and conveyancing law, which requires transaction-specific review.
The strongest contrary argument is that a token represents only the asset and gives each holder direct control. That argument succeeds only if the legal documents and situs law support direct ownership or use, the holder is not relying on pooled management for returns, and no separate security right exists. Fractionalization, passive rent, promoter-managed resale, pooled expenses, or an SPV usually weakens it.
Custody, title, and insolvency
Custody analysis starts after classification. It asks what property the client owns, who holds it, what record proves ownership, and what happens when an intermediary fails. Four layers must remain separate: the substantive right, the authoritative register, control of transfer credentials, and any account claim against an intermediary.
Private-key control addresses only one layer. A custodian may possess the key while holding the asset as agent for clients. It may hold an omnibus onchain position while client rights exist only in its internal books. A client may hold a key to a token that represents only an unsecured claim against the wrapper issuer. The legal documents and insolvency law decide ownership and priority.
The authoritative register must be stated expressly. An issuer-native system may make the ledger definitive. Another design may treat the blockchain as a mirror of an offchain register. Conflicts can arise when the two records diverge after a fork, administrative correction, court order, network outage, or unauthorized transfer. The terms should identify which record controls, who may correct it, the legal basis for correction, and the holder’s remedy.
United States broker-dealers must obtain and maintain possession or control of customers’ fully paid and excess margin securities. They also maintain customer reserve accounts under Rule 15c3-3. 17 C.F.R. § 240.15c3-3(b), (e). Registered investment advisers with custody generally use a qualified custodian that holds assets in client-named accounts or client-only accounts under the adviser’s name as agent or trustee. 17 C.F.R. § 275.206(4)-2(a)(1). Registered funds face separate custody requirements under Investment Company Act section 17(f) and its rules, including Rule 17f-4 for security entitlements held through a securities depository. 15 U.S.C. § 80a-17(f); 17 C.F.R. § 270.17f-4.
Those rules do not treat a key as a complete legal answer. The broker-dealer must be able to transfer the security, protect credentials, assess the network, maintain records, and respond to incidents. SEC staff described those operational considerations in December 2025, but the statement is nonbinding and limited to Rule 15c3-3(b)(1). SEC Division of Trading and Markets, Statement on the Custody of Crypto Asset Securities by Broker-Dealers (Dec. 17, 2025).
EU investment firms must protect client ownership rights, particularly on insolvency, and must not use client instruments for their own account without express consent. Directive 2014/65/EU, art. 16(8). Their records must distinguish each client’s assets from other clients’ assets and the firm’s own assets, and must support an audit trail. Commission Delegated Directive (EU) 2017/593, arts. 2–3. UCITS and alternative investment funds also require depositary safekeeping or ownership verification under Directive 2009/65/EC, arts. 22–22b, and Directive 2011/61/EU, art. 21.
UK custody of security tokens remains subject to the activity of safeguarding and administering investments under article 40 of the Regulated Activities Order and the applicable CASS 6 rules. The firm must map the token to the client’s legal asset and maintain records that support client ownership and return. The broader cryptoasset safeguarding regime in S.I. 2026/102 does not reach full commencement until October 25, 2027.
Swiss custody places direct weight on segregation and insolvency recovery. The Banking Act and Debt Enforcement and Bankruptcy Act permit segregation of qualifying crypto-based client assets when statutory conditions are met. Banking Act, SR 952.0, art. 16 no. 1bis, art. 37d; Debt Enforcement and Bankruptcy Act, SR 281.1, art. 242a. FINMA’s nonbinding Guidance 01/2026 states that supervised institutions should examine client allocation, technical capability, foreign prudential supervision, and equivalent bankruptcy protection when custody is delegated abroad.
Hong Kong’s SFC requires intermediaries and product providers to examine ownership recording, network risks, custody, onchain and offchain finality, transfer restrictions, smart-contract controls, and business continuity. SFC Circular 23EC52, paras. 8–20; SFC Circular 26EC22, paras. 10–17. The product provider remains responsible for the ownership record despite outsourcing.
A custody opinion should therefore answer more than “who has the key.” It should state the holder’s legal asset, account type, register entry, custodian capacity, segregation method, subcustody chain, governing insolvency law, recovery procedure, and treatment of shortfalls. Without those answers, the custody structure remains legally incomplete.
Trading, settlement, and finality
Security classification determines which trading and settlement rules apply. An automated protocol can perform regulated functions even when no participant uses traditional labels. Counsel must identify who solicits orders, matches trades, deals as principal, provides advice, operates the venue, maintains the issuer register, clears obligations, settles the cash leg, and holds client assets.
Technical confirmation does not by itself establish legal finality. The operating rules must define when an order enters the system, when it becomes irrevocable, when cash is discharged, and when the buyer acquires the security. They must also address failed trades, chain reorganization, forks, erroneous minting, administrative freezes, and court-ordered reversals.
In the United States, Rule 15c6-1 generally bars a broker-dealer from contracting for payment and delivery later than the first business day after trade date, absent an exclusion or an express agreement at the transaction. 17 C.F.R. § 240.15c6-1(a). The rule sets an outside contractual date. It does not require every transaction to settle exactly on T+1, and it does not validate a settlement system that fails other Exchange Act duties.
In the European Union, CSDR generally requires transferable securities admitted to trading to be represented in book-entry form and sets an intended settlement date no later than the second business day for venue trades. Regulation (EU) No 909/2014, arts. 3, 5. A CSD must define entry and irrevocability, disclose finality rules, take reasonable steps to achieve finality by the end of the actual settlement date, and use delivery versus payment for cash trades between direct participants. Id. arts. 39–40.
The EU DLT Pilot Regime permits authorized DLT market infrastructures to seek targeted exemptions from selected MiFID II and CSDR requirements. Regulation (EU) 2022/858, arts. 4–7. It applies only to eligible DLT financial instruments and imposes value thresholds. Id. art. 3. It does not turn a financial instrument into a MiCA cryptoasset or remove issuer, offer, market-abuse, and investor-protection duties that remain applicable.
The UK Digital Securities Sandbox follows a comparable logic. Approved firms may test notary, maintenance, settlement, and trading functions under modified legislation. Financial Services and Markets Act 2023 (Digital Securities Sandbox) Regulations 2023, S.I. 2023/1398. Live activity requires the relevant sandbox approval and ordinary FCA permissions that were not modified. Participation does not change the specified-investment status of bonds, shares, or fund units.
Switzerland authorizes DLT trading facilities that can combine trading with clearing, settlement, and custody functions for DLT securities. Financial Market Infrastructure Act, SR 958.1, arts. 73a–73f. The facility remains a licensed financial market infrastructure. The underlying rights must still satisfy the Code of Obligations and the applicable securities or fund law.
Hong Kong now permits retail on-platform secondary trading of approved tokenized investment products through SFC-licensed virtual asset trading platforms. The April 20, 2026 circular is principally directed to SFC-authorized open-ended funds. It requires controls for price deviation from indicative net asset value, liquidity, market making, interoperability between primary and secondary channels, settlement disclosure, prefunding, and prior SFC consultation or approval. SFC Circular 26EC23, paras. 6–21.
These sandbox and product routes support controlled deployment. They do not create a general exemption for decentralized trading or self-executing settlement. A transaction outside the approved perimeter remains subject to ordinary licensing, venue, offer, custody, and settlement law.
Current jurisdictional positions
United States. The boundary begins with Securities Act section 2(a)(1), Exchange Act section 3(a)(10), and binding Supreme Court tests. The SEC’s March 2026 Commission interpretation states that a security remains a security whether represented onchain or offchain. It also distinguishes issuer tokenization from third-party tokenization. Release Nos. 33-11412 and 34-105020, 91 Fed. Reg. at 13721. Bonds, fund units, SPV shares, and property interests meeting Howey therefore remain inside existing federal statutes. State commercial, property, and insolvency law can still determine title, perfection, and securities entitlements. The CLARITY Act remained pending and does not change this answer.
European Union. MiCA does not apply to a token that qualifies as a MiFID II financial instrument. Regulation (EU) 2023/1114, art. 2(4)(a). A tokenized bond normally qualifies as a transferable security. A fund token qualifies as a unit in a collective investment undertaking. A unique direct-property credential may fall outside MiCA under article 2(3), yet national law still decides its title effect. Fractional, negotiable, or pooled claims can fall back within MiFID II. CSDR, MiFID II client-asset rules, and UCITS or AIFMD depositary duties then govern the relevant functions. The DLT Pilot Regime supplies only authorized, targeted modifications.
United Kingdom. FSMA section 19 prohibits regulated activity without authorization or exemption. Tokenized shares, debt, and fund units remain specified investments under the Regulated Activities Order. Rights or interests in those investments can also fall within article 89. A pooled property structure can be a collective investment scheme under FSMA section 235. CASS 6 governs custody of specified-investment tokens where applicable. The Digital Securities Sandbox modifies selected infrastructure rules for approved participants. FCA PS26/7 permits DLT unit-holder registers for authorized funds within the existing fund rules. The 2026 cryptoasset regulations take full effect in 2027, not on the present date.
Switzerland. Code of Obligations articles 973d–973i permit qualifying rights to exist and transfer as ledger-based securities. FinMIA and FinSA separately determine when those rights are securities, DLT securities, or financial instruments and which trading or service licenses apply. CISA governs pooled investment assets and their custody. Swiss land ownership still requires the land-register entry prescribed by Civil Code article 656. FINMA’s January 2026 custody guidance places emphasis on client allocation, technical control, prudential supervision, and insolvency segregation.
Hong Kong. The SFO securities definition captures traditional bonds, fund interests, and many interests in collective investment schemes. The SFC treats DLT representation as a wrapper around those rights. SFC Circular 23EC52, paras. 5–7. Offers and intermediary activity remain subject to Part IV of the SFO, the C(WUMP)O prospectus provisions, licensing, and conduct duties. The 2026 product circulars add a controlled path for primary dealing and selected retail secondary trading, while preserving ownership-record, disclosure, custody, pricing, and liquidity duties.
Transaction design and diligence priorities
The classification opinion should begin with a rights schedule. It should name the issuer or obligor, the underlying asset, the holder’s contractual and proprietary rights, payment source, voting rights, redemption rights, transfer limits, enforcement remedy, and governing law. It should then test each right against the named security and collective-investment categories.
The documents should state whether the token is the instrument, evidence of the instrument, or a wrapper claim. They should identify the authoritative register and the legal effect of minting, transfer, burning, freezing, and correction. A wrapper structure also needs an analysis of backing, custody, perfection, shortfalls, set-off, and the wrapper issuer’s insolvency.
Property transactions require a separate situs-law opinion. That opinion should address whether the token transfer conveys land, a beneficial interest, an entity interest, or only a contract right. It should also address registration, notarization, foreign-ownership limits, taxes, mortgage consent, tenant rights, and enforcement.
The activity map should assign each function to a legal person. Issuance, promotion, placement, dealing, advice, management, matching, venue operation, register maintenance, custody, clearing, cash settlement, and redemption can trigger different permissions. Automation may change who performs a step, but it does not remove the step.
The custody and settlement design should be tested against failure. The analysis should cover loss of keys, compromised administrators, ledger divergence, custodian and subcustodian insolvency, settlement-asset failure, network outage, fork, erroneous transfer, sanctions freeze, and court order. The documents must allocate authority, loss, correction rights, and client remedies for each event.
