What Is Crypto Taxonomy? The SEC's 5 Asset Categories
For years, a trader holding Bitcoin, XRP and an NFT could not say with confidence which rulebook applied to each. Regulators answered through lawsuits, not definitions, and a token could be a security in one court filing and not in another. A taxonomy replaces that guesswork with named buckets. This guide explains the buckets, shows which real tokens tend to sit in each, and gives you a repeatable way to classify your own holdings.
What crypto taxonomy means
A taxonomy is a structured way of grouping things. In crypto, it groups digital assets by what they do and how they are sold. The goal is to answer one legal question: is this asset, or the way it was sold, an investment contract under US securities law?
The US test dates to the 1946 Howey case: an investment of money in a common enterprise with an expectation of profit from the efforts of others. Until recently, regulators applied that test token by token, usually after a dispute started. The 2026 SEC interpretation, described in the SEC press release on applying federal securities laws to crypto assets, organizes the question into categories. The accompanying SEC fact sheet summarizes the release.
Do not confuse taxonomy with tax treatment. In the US, the IRS has treated virtual currency as property since Notice 2014-21. A token's SEC category does not by itself change how your gains are taxed.
The five categories, with real examples
The SEC materials describe five groups. Token examples below are illustrative mappings based on how each asset works. Unless the release names an asset explicitly, treat the mapping as analysis, not an official ruling. Prices are real-time market data as of November 7, 2026.
-
Digital commodities
These are tokens whose value comes from the operation of a functioning network and market supply and demand, not from a company's promises of future profit. Bitcoin ($75,852), Ethereum ($2,239) and Solana ($90.14) are the usual reference points because their networks run without a central operator. XRP ($1.1800) is a well-known litigated case. In July 2023, a federal court in the Ripple case distinguished between institutional sales and programmatic exchange sales, which is why XRP is a common test example for taxonomy questions.
Regulatory angle: The token itself is not treated as a security. The CFTC has a role over commodity markets, and the sale of a token can still raise securities questions if the seller makes ongoing promises.
-
Digital collectibles
These are assets bought for ownership, display or culture rather than as a financial return: NFT art, music, trading cards, in-game items. Meme coins are often discussed in this group. In February 2025, SEC staff said certain meme coins generally do not involve securities transactions. Dogecoin ($0.0724) is the best-known example, though it is also traded as a payment-style commodity token, so placement is debated.
Regulatory angle: Generally outside securities law. The exception is fractionalized or yield-promising NFT schemes, which look like investment contracts.
-
Digital tools
Tokens that perform a practical function: memberships, tickets, credentials, identity badges, access passes. Their value is tied to use, not to profit expectations.
Regulatory angle: Generally outside securities law. A "utility" label gives no protection if the token is marketed mainly as an appreciating investment.
-
Stablecoins
Tokens designed to hold a fixed value, typically one US dollar. USDT and USDC are well-known examples. In the US, payment stablecoins have their own statute, the GENIUS Act, signed in July 2025.
Regulatory angle: Governed mainly by stablecoin-specific rules on reserves and issuer licensing, not by the commodity-versus-security question.
-
Digital securities
These are tokenized versions of traditional securities, such as shares, bonds or fund interests, and any token sold as an investment contract. The blockchain is just the ledger. The legal wrapper is still a security.
Regulatory angle: Full SEC regime: registration or an exemption, disclosures, and licensed intermediaries.
Categories at a glance
| Category | Core test | Example assets | Primary rulebook |
|---|---|---|---|
| Digital commodities | Value from network use and market supply and demand | Bitcoin, Ethereum, Solana, XRP | Commodity law; securities law only if sold via investment contract |
| Digital collectibles | Bought for ownership or culture | NFT art, trading cards, some meme coins | Mostly outside securities law |
| Digital tools | Practical function or access | Tickets, memberships, credentials | Mostly outside securities law |
| Stablecoins | Fixed-value, payment-oriented | USDT, USDC | Stablecoin-specific statute (GENIUS Act in the US) |
| Digital securities | Investment contract or tokenized traditional security | Tokenized shares and bonds | Federal securities laws |
Old approach vs. the 2026 approach
| Dimension | Pre-2026 approach | 2026 taxonomy approach |
|---|---|---|
| Method | Case-by-case Howey analysis | Named categories applied to Howey |
| How rules emerged | Mostly enforcement actions and court rulings | Published interpretive release and fact sheet |
| Predictability for issuers | Low; outcomes varied by court | Higher; categories give a starting point |
| Agency coordination | SEC and CFTC claimed overlapping turf | SEC and CFTC coordination on which assets sit where |
| Treatment of stablecoins | Unclear until statute | Own category, tied to the GENIUS Act |
One caveat: an interpretive release is guidance, not a statute. It shows how the agency will read existing law, and a court is not bound to agree. Congress could still legislate a different structure.
How to classify a token: step by step
This is a practical decision path for retail holders. It is a screening aid, not legal advice, and borderline tokens need a lawyer.
- Is it pegged to a currency and used for payments? If yes, it is likely a stablecoin. Check the issuer's reserve disclosures.
- Is it a digital wrapper for a share, bond or fund interest? If yes, it is a digital security regardless of the blockchain used.
- Does it unlock a specific function, such as access, a ticket or a credential? If yes, it likely belongs in digital tools.
- Is it a unique or limited item bought for ownership or culture? If yes, it likely belongs in digital collectibles.
- Does it run on a live, decentralized network with no single party promising returns? If yes, it is a candidate for digital commodity status.
- Did the seller promise profits, buybacks, yield or roadmap-driven price growth? If yes, the sale may be an investment contract even if the token itself fits a non-security category.
Gray-zone examples: governance tokens such as Uniswap's UNI and oracle tokens such as Chainlink's LINK do not map cleanly to one bucket. Their classification depends on the specific facts of how they were distributed and what rights they carry. Check the primary SEC text for any named lists before assuming a result.
Compliance implications by category
| Category | Who has obligations | Typical obligations |
|---|---|---|
| Digital commodities | Exchanges, brokers, issuers who sell via contracts | AML and KYC; anti-fraud rules; securities compliance only where an investment contract exists |
| Digital collectibles | Marketplaces, creators | AML where applicable; avoid profit-sharing features that look like securities |
| Digital tools | Issuers, platforms | Marketing discipline; describe function, not returns |
| Stablecoins | Issuers, custodians | Reserve backing, redemption, licensing under stablecoin law |
| Digital securities | Issuers, broker-dealers, trading venues | Registration or exemption, disclosures, licensed intermediaries |
For individual holders, compliance mostly means tax reporting and using regulated venues. The category shapes which products an exchange can offer you and how it describes them.

International taxonomies beyond the US
The US is not the only jurisdiction sorting tokens into groups, and the labels differ.
- European Union: The Markets in Crypto-Assets Regulation (MiCA) separates asset-referenced tokens, e-money tokens and other crypto-assets.
What it means for traders
From the trader's desk, the taxonomy matters in four places.
- Listing risk: Tokens that clearly fit a non-security category are easier for US-regulated venues to list. Gray-zone tokens carry more delisting and halt risk.
- Product access: Tokenized securities usually require a licensed venue and may restrict who can buy them.
- Headline sensitivity: A reclassification story can move a token, with XRP's 24-hour move of -3.16% on November 7, 2026 a reminder that regulatory-adjacent assets react to news. Do not assume cause without evidence.
- Due diligence: A category is a starting point. Read how a token was distributed and what the team promised.
Editor's note on common mistakes: Holders often assume "utility token" means "not a security." The label has no legal force. What matters is how the token was sold and what buyers were led to expect. Another frequent error is treating one asset as a single permanent category. The SEC and courts look at the asset and the transaction separately, so the same token can be fine to hold yet problematic as originally sold. Finally, a taxonomy guidance document is not a safe harbor for fraud: anti-fraud rules apply in every category. Market figures above come from real-time market data as of November 7, 2026, and the interpretive text should be read in full.

FAQ
What is crypto taxonomy?
Crypto taxonomy is a classification system that groups digital assets by function, such as commodity, collectible, tool, stablecoin or security. Its purpose is to decide which legal rules apply to creating, selling and trading each type.
How does the SEC's crypto taxonomy work?
The SEC applies the long-standing investment contract test to each asset type. It sorts tokens into five categories. Then it asks whether the token itself, or the way it was sold, creates an investment contract.
Is it safe to rely on a token's category?
No. A category describes the legal treatment, not the risk of losing money. Price volatility, hacks and fraud exist in every category, and anti-fraud laws apply to all of them.
Why does crypto taxonomy matter to retail investors?
It affects which exchanges can list a token, what disclosures issuers must give, and how products are marketed to you. It does not change your tax obligations by itself.
How can I tell which category my token falls into?
Work through the step-by-step path above: check for a currency peg, a securities wrapper, a practical function, a collectible nature or a decentralized network. Then check how the token was sold. For borderline cases, consult a securities lawyer.
