Security Entitlement
Definition
A security entitlement is, in the words of Article 8 of the Uniform Commercial Code, 'the rights and property interest of an entitlement holder with respect to a financial asset' (UCC 8-102(a)(17)). It is how almost every investor in US stocks and bonds actually holds them: the shares are registered to a depository's nominee, the depository credits a broker, and the broker credits the customer's account. The customer does not own a specific share; the customer has an entitlement against the broker, which is the 'securities intermediary', and the broker must hold enough of that security to cover every customer's entitlement. Article 8 gives entitlement holders a pro rata property interest in the intermediary's holdings of that financial asset and keeps those holdings out of the reach of the intermediary's general creditors. In tokenization, SEC staff describe the custodial model as one where a third party 'tokenize[s] a security issued by another person by creating a security entitlement that is formatted as a crypto asset', so that 'the crypto asset represents the holder's indirect interest in the underlying security via the security entitlement' (Statement on Tokenized Securities, January 28, 2026).
Why it matters
The security entitlement is the legal concept that separates a custodial token from a synthetic one, and most marketing does not use the term. A token issuer that holds shares for holders as their securities intermediary has given them a property interest the issuer's creditors cannot reach; a token issuer that holds shares for itself and owes holders a payment has given them a claim the issuer's creditors share. Both can say 'backed one-for-one'. SEC staff placed tokenized security entitlements in the custodial model in January 2026 and said they view the 'digital custodial receipt' model the same way. AltStreet's reviews show how the line falls in practice: Dinari's US product, launched August 4, 2026, records positions in brokerage accounts carried by Alpaca Securities, where customer protection is the broker-dealer and SIPA framework; its non-US product, and Backed's xStocks and Ondo Global Markets' notes, are issuer obligations instead. For an investor, the presence or absence of an Article 8 entitlement is the difference between owning a slice of a custodied pool and lending to the token issuer.
Common misconceptions
- •An entitlement is not a second-class ownership. It is how the US market holds most securities, and Article 8 protects holders ahead of the intermediary's general creditors.
- •An entitlement is not ownership of particular shares. Holders of the same security at an intermediary share its total holdings pro rata; a shortfall is shared too.
- •Entitlement protection is not absolute. A secured creditor with control of the securities can rank ahead of entitlement holders (UCC 8-511(b)), which is why sound intermediaries do not pledge customer securities beyond what rules permit.
- •Calling a token an entitlement does not make it one. The relationship must be set up in the account terms with a party acting as securities intermediary under a governing law that applies Article 8.
- •SIPC protection does not cover losses in value. It covers missing customer property at a failed SIPC-member broker-dealer, up to the statutory limits, not market declines, and it does not apply to non-member token issuers.
Technical details
The statutory framework (UCC Article 8, Part 5)
Definition: 'security entitlement' means the rights and property interest of an entitlement holder with respect to a financial asset specified in Part 5 (UCC 8-102(a)(17)); an 'entitlement holder' is a person identified in an intermediary's records as having a security entitlement against it (8-102(a)(7)).
Creation: a person acquires an entitlement when the intermediary indicates by book entry that a financial asset has been credited to that person's account (8-501(b)). The holder does not need to show the intermediary holds the asset.
Property interest: to the extent necessary to satisfy entitlements, financial assets held by an intermediary are held for entitlement holders, are not property of the intermediary, and are not subject to claims of its creditors, except as 8-511 provides (8-503(a)); holders' interests are pro rata (8-503(b)).
Duties: maintain a sufficient quantity of each financial asset (8-504), obtain and pass through payments and distributions (8-505), exercise rights as directed (8-506), comply with entitlement orders (8-507), and change the holder's position to another form of holding on request (8-508).
Priority: entitlement holders have priority over the intermediary's creditors in a shortfall, except a secured creditor with control (8-511).
The holding chain for a US listed share
The issuer's register shows Cede & Co., the nominee of The Depository Trust Company, as record holder of most publicly held shares.
DTC credits participant brokers and custodian banks; each holds a security entitlement against DTC.
Each broker credits its customers; each customer holds a security entitlement against the broker.
The customer is the beneficial owner. Dividends and proxy materials pass down the chain; votes pass back up.
SEC staff cite this indirect system (the 2010 Concept Release on the U.S. Proxy System) and DTC's December 11, 2025 no-action letter when describing tokenized security entitlements.
What a tokenized entitlement changes and does not
Changes: the intermediary's record of entitlement holders may be kept on a blockchain, so that a token transfer is the book entry that moves the entitlement; or the records stay off-chain and the token instructs the intermediary to update them. Either way, staff say 'the format in which the security entitlement is issued does not affect application of the federal securities laws'.
Does not change: the intermediary's duties, the holders' pro rata property interest, the priority rules, or the need for the intermediary to actually hold the security.
Adds: smart contract and key risk in the record itself, administrator powers to freeze or correct, and the question whether an on-chain transfer between two holders is effective as an entitlement order if the intermediary has not recorded it.
Insolvency of the intermediary: the order of events
Identify the securities held for entitlement holders of each financial asset; they are outside the intermediary's general estate (8-503).
Compare holdings with entitlements. If sufficient, transfer each holder's position to a solvent intermediary or deliver it. If short, allocate pro rata within that financial asset (8-503(b), 8-511).
Check secured creditors with control of any of those securities; they take ahead of entitlement holders (8-511(b)).
For a SIPC-member US broker-dealer, a SIPA trustee returns customer property and SIPC advances cover missing property up to $500,000 per customer, including $250,000 for cash.
For a non-US or non-SIPC token issuer, the local insolvency law and the token terms govern, and protections may be weaker or absent.
Diligence questions for a custodial token
Do the token terms say the token is, or represents, a security entitlement, and name the securities intermediary?
Which law governs (the securities intermediary's jurisdiction), and does it apply Article 8 or an equivalent?
Where are the underlying securities held, in whose name, and are customer securities segregated from the intermediary's own?
Can the intermediary pledge, lend or rehypothecate the securities, and to whom?
Is the intermediary a SIPC member, a registered broker-dealer, a bank or a trust company, and is there an attestation of holdings against tokens outstanding?
Frequently asked questions
- What rights do I have if my token represents a security entitlement?
- The rights Article 8 gives any entitlement holder against its securities intermediary: the intermediary must obtain and keep enough of the security to cover all entitlements (8-504), pass through payments and distributions it receives (8-505), exercise rights such as voting as you direct (8-506), follow your instructions to transfer (8-507), and deliver the security or move it to another intermediary on request where the terms allow (8-508). You also have a pro rata property interest in the intermediary's holdings of that security, which are not its property for its general creditors (8-503). Tokenizing the entitlement changes the format of the record, not these rights, provided the documents actually set up an Article 8 relationship.
- What happens to a security entitlement if the intermediary goes bankrupt?
- The securities held for entitlement holders are not property of the intermediary available to its general creditors (UCC 8-503(a)), so they should be returned or transferred to holders rather than used to pay the intermediary's debts. If the intermediary is short, holders of that security share what there is pro rata (8-503(b)), and holders have priority over the intermediary's general creditors (8-511(a)). The main exception is a secured creditor of the intermediary that has control of the securities, which ranks ahead of entitlement holders (8-511(b)). For a failed US broker-dealer, the Securities Investor Protection Act liquidation process returns customer property and SIPC covers shortfalls up to $500,000 per customer, including up to $250,000 for cash.
- Is a security entitlement the same as owning the share?
- Economically close, legally different. You do not hold a specific share or appear on the issuer's register; you hold rights against your intermediary and a share of its holdings. That is how most investors already own stocks at brokers, and it works well when the intermediary keeps accurate records and enough securities. Its weak points are intermediary shortfalls, secured creditors with control, and operational delays in a failure.
- What is a securities intermediary?
- Under UCC 8-102(a)(14), a clearing corporation, or a person (including a bank or broker) that in the ordinary course of its business maintains securities accounts for others and is acting in that capacity. Brokers, custodian banks and depositories are the usual examples. In a custodial tokenization model, the party that holds the underlying security and maintains the token records acts in this role, and whether it actually qualifies, under which state's law, is a question for its documents and legal opinions.
- Does every tokenized stock give me a security entitlement?
- No. Only custodial structures do. Issuer-sponsored tokens are the security itself, recorded on the issuer's register. Synthetic tokens are the token issuer's own instrument, a note or swap whose value tracks the security, and give no entitlement to the underlying. A token issuer that holds shares one-for-one but issues debt certificates to holders, as several offshore issuers do, has created a creditor relationship, not an entitlement.
- Where does the law that governs my entitlement come from?
- From the 'securities intermediary's jurisdiction', which Article 8 lets the account agreement choose (UCC 8-110(e)); in practice US custodial arrangements usually choose New York or Delaware law. An entitlement held through an intermediary outside the US is governed by that country's law, which may not have Article 8's protections. For a tokenized entitlement, the governing-law clause in the token terms is the place to look.
