The SEC grouped crypto assets into categories in a March interpretation

A product page can now point to an official box. Digital commodity. Collectible. Tool. Stablecoin. Digital security. The box is real. The mistake is treating the box as a hall pass.

On March 17, 2026, the Securities and Exchange Commission issued a joint-agency interpretation with the Commodity Futures Trading Commission. The release groups crypto assets into those five categories and walks through airdrops, protocol mining, protocol staking, wrapping, and the point at which an investment contract can end. Chairman Paul S. Atkins called it a way to "draw clear lines in clear terms." He also said the interpretation "reflects the reality that investment contracts can come to an end" and that "most crypto assets are not themselves securities." Those sentences are Commission-level views in a published interpretation. They are not a finding that a named token, sold a particular way, sits outside the statutes.

The useful shift is a method. Separate the asset from the transaction, promise, or managerial relationship built around it. A payment token can be sold through an investment contract. A non-security asset can be wrapped into a security. A tokenized security can carry different rights from its offchain reference. The ticker is the least informative fact in that chain. The Commission's plain-language guide, posted in April, makes the last point without ornament. "The rights of a holder of the crypto asset may be materially different from the rights of a holder of the underlying security, including economic and voting rights." That sentence is the edge of the taxonomy. Category membership describes the thing. Holder rights describe the legal wrapper. Marketing that compresses those distinctions into a claim that an agency has declared the asset safe, or unregulated, is selling a reading the documents do not support. Retail holders bear the disclosure and counterparty cost of that compression. Issuers, exchanges, and developers still depend on facts that do not fit in a symbol: who promised what, who still performs essential efforts, which intermediary stands between the user and the claim, and which regulator is being asked to treat the arrangement as closed. Protocol code, operator discretion, user expectation, and the legal instrument are four different objects. The interpretation is a method for keeping them apart. It is not a substitute for naming them. What the March release is, and is not, should stay in view. It is a Commission interpretation, joined by CFTC guidance that the CFTC and its staff will administer the Commodity Exchange Act consistent with that reading. It is not a statute. Congress may still redraw the division of authority between the two agencies. Courts may test how the taxonomy sits next to older precedent. Examinations, registrations, and enforcement choices will show whether the method is applied the same way twice. The Chair's July statement on the 2026 regulatory agenda is a different kind of document: an official's view of work still ahead. Atkins described rulemaking to "bring more products onshore, creating clear rules of the road for capital raising with crypto assets, and providing clarity as to how market participants can custody and facilitate trading of tokenized securities onchain." Planned rulemaking is not the interpretation. Proposed rules, if they come, are not the interpretation. Staff speeches are not the interpretation. Binding, proposed, and personal remain three labels, and they do not travel together. The standing test is concrete. Name the asset, the transaction, the intermediary, the customer promise, and the regulator. Then say which part of the analysis is binding, which is proposed, and which is merely an official's view. The taxonomy has edges because the deal still has them.
