What Is the SEC's Role in Crypto? How US Securities Law Applies in 2026

The SEC finally drew its lines on crypto. Four things matter if you build on them.

• Most of the crypto your users know isn't treated as a security. Bitcoin and Ether count as commodities, closer to gold than to company shares.

• How a token is sold can change that. Promise buyers a profit from your team's work, and securities law comes back.

• The lines can still move. They rest on the SEC's reading of the law, not on a law Congress has passed.

• Staying outside the SEC doesn't mean staying outside every rule. Anyone who swaps crypto for cash still has to check who their users are.

The SEC administers and enforces US federal securities laws. It supervises stocks, bonds, funds, and anything that qualifies as an "investment contract" under the Howey Test, the 1946 Supreme Court standard for spotting investments in disguise. The 2026 interpretation confirms Howey still governs crypto.

Under Howey, an investment contract has three elements:

• An investment of money,

• In a common enterprise,

• With a reasonable expectation of profits derived from the efforts of others.

All three matter. Buying a token to use it is not a security. Funding a project and counting on its team to generate returns can be one. When an investment contract exists, the transaction falls under federal securities laws and generally must be registered unless an exemption applies.

Crypto never fit that mold cleanly, which is where the trouble started. Many tokens were sold with promises of future profit tied to the issuer's own work, which is exactly what Howey flags as a security, yet they also worked as usable products. For years the SEC resolved that tension case by case, through enforcement rather than published rules.

Where securities laws apply, a token launch picks up obligations that take time and legal work to meet. Depending on the issuer, offering, and transaction, and absent an exemption, that can mean:

• Registration with the SEC before the token is offered.

• Ongoing disclosures, including audited financials.

• Trading through a registered broker-dealer, the kind of firm licensed to handle securities trades.

Classification decides which of these obligations apply.

In a few years, the SEC went from suing crypto companies to writing rules for them. That shift explains why the 2026 lines exist, and why they could still move.

Under former Chair Gary Gensler, the SEC addressed crypto mainly through enforcement. By his own tally, his commission brought about 100 crypto enforcement actions, including lawsuits against Coinbase and Binance, before he stepped down in January 2025.

The industry called it regulation by lawsuit. Gensler, in his exit interview, called crypto "rife with bad actors." Critics argued that, without clear rules, enforcement had become the policy. A lawsuit settles one company's dispute, but it doesn't tell the next project where it stands.

His successor, Republican former commissioner Paul Atkins, arrived with the opposite mandate. One of his major early initiatives was Project Crypto, launched in July 2025 to write actual rules, which he later turned into a joint effort with the CFTC, the agency that oversees commodity and derivatives markets.

When the joint interpretation landed in March 2026, Atkins told a Washington audience the agency was "no longer the Securities and Everything Commission." It was a striking line from a commission that had spent the previous four years suing the industry.

The interpretation, issued on March 17, 2026, sets out five principal categories for analyzing crypto assets. It also notes that some assets may fall outside all five, or share features of several, so the labels don't cover every token cleanly.

Two caveats. A crypto asset that is not itself a security can still be sold subject to an investment contract if the issuer markets it with profit promises. And the rules against fraud and market manipulation apply whichever category the asset falls into.

How firm is this line? It's an interpretation, effective March 23, 2026. It tells you how the SEC reads existing law and, in its own words, doesn't create any new legal obligations. A future Commission can revisit it.

The best-known tokens now sit outside securities law. What matters is which ones, and where the exceptions are.

The SEC's own guidance lists 16 tokens as primary examples of digital commodities: Bitcoin, Ether, Solana, XRP, Cardano, Dogecoin, Chainlink, Avalanche, and eight others.

Solana and Cardano were among the tokens the SEC alleged in its 2023 Coinbase complaint were offered and traded as securities. Three years later, the same regulator treats them as commodities.

Don't overread the relief. The interpretation states that past registration violations are not cured by the new framework. Projects sued under the old regime don't get a retroactive pass.

Memecoins fall under collectibles, treated more like trading cards than shares. Stablecoins depend on their type:

The GENIUS Act became law in July 2025 and sets a federal framework for payment stablecoins. Its rules aren’t in force yet. Regulators are still finalizing them, and the Act takes effect on January 18, 2027.

Tokens that are still securities get some relief too, at the level of the apps people trade them through. On April 13, 2026, SEC staff said they would not object if certain interfaces that help users trade crypto asset securities from their own self-custodial wallets (where users hold their own keys) operated without registering as broker-dealers, the license stockbrokers operate under, as long as they meet the statement’s conditions.

The relief has three limits:

• It's conditional. The statement sets detailed conditions on how the interface handles orders, fees, conflicts of interest, and disclosures.

• It's staff guidance. It reflects the view of SEC staff, not a formal exemption voted by the Commission.

• It's temporary. It's deemed withdrawn five years after it was issued, unless the Commission acts.

For wallet and DeFi front-end builders, the statement lowers the risk that publishing an interface alone makes them unregistered broker-dealers, as long as they stay inside its conditions. Of all the lines in this guide, it's the easiest to move.

Tokenized stocks, by contrast, stay on the SEC's side of the line. A share of Apple doesn't stop being a security because it lives on a blockchain.

The interpretation coordinates how the SEC and CFTC treat crypto assets without changing what either agency is allowed to do by law. CFTC Chairman Mike Selig co-signed it and committed the CFTC to applying commodity law in line with it.

Compliance teams start with classification; the regulator, the registration path, and the disclosure load follow from it.

The March interpretation classifies tokens, but it doesn't set out how to register or offer one. Regulation Crypto Assets, the SEC's proposed crypto-specific offering regime, is meant to supply that missing piece. The SEC proposed it on August 18, 2026, and is taking public comments until October 20.

As proposed, it sketches three pathways out of full securities registration:

• Startup exemption: offerings of up to $5 million over four years, with simplified disclosures instead of a complete filing, while the project is early and still proving itself.

• Fundraising exemption: offerings of up to $75 million a year, for maturing projects that outgrow the startup track.

• Investment contract safe harbor: a conditional path for a token that has matured to stop being treated as part of an investment contract, once the founders have finished the work they promised and the network runs on its own.

A final rule would be firmer ground than anything in place today. Staff can withdraw a statement at will, and a Commission can revisit an interpretation, while a rule survives a change of chair unless a later rulemaking undoes it.

Congress has a firmer route still in the CLARITY Act, which would write the lines into law. It hasn't passed: the Senate Banking Committee advanced it by a 15–9 vote on May 14, 2026, but on September 15 it failed a procedural vote to bring it to the Senate floor, 49–50. The SEC isn't waiting for it.

Until the rule or a bill lands, the five categories are the working map. Teams planning US market entry can use them to check each token they list, write down the reasoning, and note which conclusions rest on staff guidance, which on the interpretation, and which would change if the rule is finalized.

No. The taxonomy answers one question: whether securities law applies. A product that lets users swap crypto for dollars, or dollars for crypto, answers a different set of rules.

Under guidance from the Financial Crimes Enforcement Network (FinCEN), the Treasury bureau that polices money laundering, businesses that exchange crypto for traditional currency generally count as money transmitters. They register with FinCEN, need money transmitter licenses in most states, run an anti-money-laundering program, and verify who their customers are. That holds for Bitcoin as much as for any token the SEC still watches.

That's why many wallets and apps don't move the money themselves. They have two routes: register as money transmitters and build those controls in-house, or integrate an on- and off-ramp provider that handles the payment, the identity check, and the conversion while the app keeps its own experience. Which one fits depends on your markets and your volume.

So a US launch comes down to two separate questions. Securities law tells you whether a token is a security; money transmission rules tell you who's allowed to move money between crypto and cash. A product needs an answer to both.
