The U.S. Securities and Exchange Commission (SEC) on Tuesday released its first-ever interpretive guidance outlining how it plans to classify different types of crypto assets under U.S. securities laws—an attempt to end years of regulatory ambiguity for exchanges, token issuers, and DeFi builders.

CoinDesk reports the guidance was issued in partnership with the Commodity Futures Trading Commission (CFTC), shortly after the two agencies announced a closer working relationship on crypto oversight. SEC Chair Paul Atkins framed the document as a ‘token taxonomy’ intended to clarify what falls inside the SEC’s jurisdiction and what does not.

Key takeaway: Atkins said the SEC’s interpretation is that most crypto assets are not themselves securities. According to his remarks, the SEC is using four broad categories and is drawing a line that only ‘digital securities’—traditional securities represented using new technology—remain squarely subject to securities laws. The guidance also addresses practical crypto activities including airdrops, protocol mining, protocol staking, and the wrapping of non-security crypto assets.

Why this matters for the market

- Exchanges and brokers: Clearer definitions could reduce the risk of retroactive enforcement and make listings and product decisions easier to justify.

- DeFi and token projects: More explicit treatment of staking and token distribution mechanisms may influence how protocols structure incentives and disclosures.

- Stablecoins and payments: By describing stablecoins and other non-security categories, the SEC may be signalling an intent to focus on investor-protection issues where securities are clearly involved, rather than treating all tokens as securities by default.

What’s next

The guidance is interpretive and does not yet carry the force of a formal rule, meaning future enforcement and court interpretations still matter. Atkins also noted that congressional legislation is the only way to make policy shifts permanent—so the durability of any pro-crypto shift may hinge on what lawmakers pass in the months ahead.
