The term covers two different systems: payment-card tokenization, which substitutes a token for a card number, and digital-asset tokenization, which represents an asset, security, or claim on a digital ledger. The risks—and the rules that apply—are not interchangeable.
What tokenization does—and what it does not
In payment-card systems, tokenization replaces a primary account number (PAN) with a surrogate value. A system may use that token for a transaction or to recognize a card on file without exposing the PAN in every connected application. Some systems can reverse the substitution, a process called detokenization. The token reduces exposure only to the extent that the PAN and the ability to retrieve it are protected.
In digital ledger technology (DLT), or blockchain-based asset tokenization, a token represents an asset, financial instrument, or claim. A token might be linked to a security held by an issuer or intermediary, but the token itself does not establish what rights its holder has. Those depend on the legal structure, governing documents, custody, and redemption arrangements.
Neither use of a token is a universal security guarantee. The PCI Security Standards Council (PCI SSC) says payment tokenization may reduce the number of systems subject to PCI DSS requirements, but it does not remove the need to maintain and validate compliance. Its tokenization guidelines describe scope reduction as dependent on the system, not the presence of a token alone.

Payment-card tokenization: where the risks remain
Token type matters
PCI SSC distinguishes three kinds of payment tokens. Their names describe different creators and frameworks; one type’s rules should not be assumed to apply to another.
| Token type | Who creates it and how it is used | Key distinction |
|---|---|---|
| Acquiring token | An acquirer, merchant, or merchant service provider creates it after card credentials are presented. Some proprietary systems support card-on-file or recurring payments. | It is not automatically an EMV payment token. |
| Issuer token | A card issuer creates it; it may take the form of a virtual card number. | Its issuer-origin does not make it equivalent to an acquiring or EMV payment token. |
| EMV payment token | A Token Service Provider (TSP) registered with EMVCo creates it for use within the EMV framework. | It has specific framework and use conditions, including fraud-prevention controls. |
PCI SSC explains these categories in its token-type FAQ. For EMV payment tokens, it says a dynamic token cryptogram and/or sufficient domain controls must be used to adequately prevent fraud. Applicability guidance for EMV tokens does not settle the compliance treatment of every other token design.
PCI DSS scope depends on data flows and access
A merchant or service provider cannot assume that a system is outside PCI DSS scope simply because it stores a token. PAN may still be accessible through a token vault, a connected system, an integration, or the path that captures the card details. PCI SSC says a system proposed for exclusion must not be able to retrieve PAN; connected systems that store, process, or transmit account data can remain in scope. See the Council’s FAQ on EMV payment tokens and PCI DSS and its tokenization guidelines.
For TSPs, the TSP Standard applies to the token data environment. Entities designated by EMVCo should confirm their validation obligations with the relevant payment brands. PCI SSC also says a conforming payment token held outside the TSP token data environment is not itself account data for PCI DSS, but that does not take other in-scope systems out of consideration. The PCI SSC TSP standard page describes the standard.
The whole payment system—not just the token string—must be protected
Exposure can arise at card capture, while data moves between systems, in token storage, or through access to a vault or detokenization function. Poor configuration or weak access controls can undermine an otherwise sound token design. PCI SSC’s product-security guidance covers tokenization solutions delivered as hardware, software, or services and emphasizes implementation, configuration, transmission, retention, and security features. A merchant evaluating scope or security needs to understand the full transaction flow and validate the result rather than infer protection from a vendor’s use of the word “token.”
DLT-based asset tokenization: risks for holders and investors
The token may not give you ownership of the referenced asset
A token can represent direct ownership, an interest recorded through an issuer, or a claim against a third party. Those structures can create different rights and different exposure if an intermediary fails. Before treating a token as equivalent to a share, bond, deposit, or physical asset, examine the governing terms: who owes the holder what, how the underlying asset is held, how ownership is recorded, and whether and how redemption works.
A January 28, 2026 statement from SEC staff describes tokenized securities as securities represented by crypto assets, with ownership records maintained in whole or in part on crypto networks. It distinguishes issuer-sponsored from third-party-sponsored structures and notes that rights can vary. This is U.S. staff guidance on securities, not a global rule for every tokenized asset. Read the SEC staff statement alongside the actual offering documents.
SEC Commissioner Hester M. Peirce put the underlying-asset issue plainly in a July 9, 2025 commissioner statement: “As powerful as blockchain technology is, it does not have magical abilities to transform the nature of the underlying asset.” She also highlighted potential counterparty risk when an unaffiliated third party issues a token tied to securities it holds. The statement is available from the SEC.

Keys, code, and governance can fail
DLT arrangements introduce operational dependencies that differ from card-number substitution. Private keys control access to tokens; losing or compromising them can create access or theft risks. Smart-contract errors can produce unintended outcomes, while unclear governance can make it difficult to respond to bugs, disputes, or system changes. Some transactions may be difficult or impossible to reverse, so recovery procedures and responsibility for errors matter before a problem occurs.
These concerns are among the operational fragilities discussed in the 2025 BIS/FSI summary of tokenization’s financial-stability implications. It also identifies reliance on service providers, interoperability limits, and links to legacy systems as risk factors. A token holder may depend on custodians, developers, platforms, or other entities even when the token is recorded on a blockchain.
Liquidity, valuation, and redemption may not line up
A token’s trading activity does not necessarily match the liquidity or value of the asset it references. The token may be difficult to redeem, the underlying asset may be hard to sell, or legal and operational frictions may delay access to it. If a token’s price and the reference asset’s value diverge, the holder needs to know which one governs redemption and who is responsible for reconciling the difference.
BIS/FSI also flags liquidity and redemption pressure, token/reference-asset mismatches, and leverage created when tokenized assets are combined across services (“composability”). These are system-design and market-structure concerns, not evidence that every tokenized product has the same risk profile. Its 2025 assessment said tokenization was then small in scale and posed minimal financial-stability risk at that time; that dated system-level assessment does not establish the safety of an individual product.

Putting a record on a blockchain does not by itself change the legal nature of the asset or remove applicable obligations. A token that represents a security may still raise securities-law questions; a token representing a different type of claim may be governed by other rules and contracts. The applicable treatment depends on the instrument, rights, participants, and jurisdiction. U.S. SEC materials should not be read as a ruling for other countries or every tokenized asset.
For one limited U.S. banking issue, the FDIC, Federal Reserve Board, and Office of the Comptroller of the Currency announced on March 5, 2026 that an eligible tokenized security should generally receive the same regulatory capital treatment as its non-tokenized form under the capital rule. The agencies also said banks holding tokenized securities must use sound risk management and comply with applicable law. This is a capital-treatment clarification, not a comprehensive resolution of custody, securities, consumer-protection, or state-law questions. See the joint agency announcement.
How to assess a tokenized service or investment
Use these questions to compare systems or offerings. The answers should come from technical documentation, contracts, and applicable compliance materials—not from the fact that a provider calls something a token.
- Identify what is being tokenized. Is it payment-card data, a security, a deposit, a physical asset, or a claim against an issuer?
- Map creation and control. Who creates the token, controls the mapping to the source data or asset, and can reverse or redeem it?
- Trace sensitive information and records. For a card system, which components capture, transmit, store, or can retrieve PAN? For an asset token, where are ownership and underlying-asset records maintained?
- Check control of keys and code. Who holds private and administrative keys? Who can change smart contracts or platform rules, and what are the recovery procedures?
- Read the holder’s legal rights. Identify the counterparty, custody arrangement, redemption terms, transfer restrictions, insolvency treatment, and process for disputes.
- List dependencies. Which custodians, service providers, developers, bridges, or legacy systems does the arrangement rely on, and what happens if one is unavailable?
- Confirm the governing regime. Determine which jurisdiction, regulator, payment brand, standard, and contractual terms apply to this particular system or offering.
For a specific merchant environment, payment-token implementation, or investment, a general guide cannot determine compliance, legal rights, or system security. Those conclusions require the actual data flows or governing documents and the rules applicable to the entity and jurisdiction.
