Are Stablecoins Securities? How the Howey Test Applies

Why this question matters more than the price of USDC

If a stablecoin is a security, the issuer must register it with the Securities and Exchange Commission or qualify for an exemption, and every exchange listing it needs to be a registered securities venue. That would reshape crypto markets overnight. If it is not a security, it can trade freely on commodity-style platforms under different rules. The classification decides who regulates, how the token can be sold, and what disclosures investors receive.

The confusion is reasonable. Some issuers voluntarily register certain products with the SEC. Some state regulators treat stablecoins like money transmitters. Some issuers hold banking charters. The public hears fragments of each regime and assumes a stablecoin is either clearly a security or clearly not. The reality is murkier, and the answer depends on which token, which issuer, and which activity you are asking about.

It is also worth saying plainly: the U.S. has no statute that names 'stablecoin' as a category. Classification is done by analogy. Lawyers take old doctrines like the Howey test and argue, often with billions of dollars on the line, whether a digital token looks enough like an old-fashioned stock or bond to fall under securities law. That analogizing is where the fight happens.

The risks of getting it wrong

For issuers, the risk is existential. If the SEC decides a stablecoin is an unregistered security, the issuer can be forced to pay disgorgement, civil penalties, and be barred from selling to U.S. persons. Coinbase and other exchanges have spent years auditing which tokens they will list precisely because of this exposure.

For users, the practical risk is more subtle. A token reclassified as a security can be delisted overnight, freezing withdrawals and tanking the secondary market. Holders of a token deemed to be an unregistered security can in theory be required to give up their holdings in a rescission, though enforcement against individual buyers is rare.

For the broader market, the risk is fragmentation. If the U.S. treats stablecoins as securities while the EU regulates them under MiCA's e-money rules and Singapore under the MAS framework, the same token can be legal in one jurisdiction and effectively banned in another. That is already happening with products like yield-bearing stablecoins, which are more aggressively restricted in the U.S. than abroad.

There is also a historical warning. The 2022 collapse of Terra UST wiped out an estimated $40 billion in value, and the subsequent SEC enforcement action against Terraform Labs became the first major case where a stablecoin issuer was treated, at least partially, as having sold securities. The ruling is narrow, but it is the only binding precedent on the books.

The Howey test, in plain English

The Howey test comes from a 1946 Supreme Court case, SEC v. W.J. Howey Co., involving citrus groves in Florida. The Court said an investment contract, which is one of the things the securities laws cover, exists when there is (1) an investment of money (2) in a common enterprise (3) with a reasonable expectation of profits (4) to be derived from the entrepreneurial or managerial efforts of others. All four prongs must be met. If any one fails, it is not a security under federal law.

Translating that to a token: prong one asks whether the buyer gave up something of value, usually dollars or crypto, to acquire the token. Almost every token sale satisfies this. Prong two asks whether the buyer's fortunes are tied to the issuer's, either through profit-sharing or pooling. Prong three asks whether a reasonable buyer expected to make money, not just to use the token. Prong four asks whether that expected profit depended on the issuer's work, not just on market forces.

The first two prongs are usually easy to meet. The action is in prongs three and four, which is where stablecoin lawyers spend most of their time. A token that is bought purely to spend, like a dollar in a digital wrapper, has a weak case for prong three. A token that is bought because the issuer promises to manage reserves, deploy capital, and grow the supply is a stronger fit.

Why most fiat-backed stablecoins argue they fail the test

USDC, USDT, PYUSD, and similar fiat-backed stablecoins share a common legal posture. They are marketed as payment instruments, not investments. The buyer is not buying a share of Circle's or Tether's revenue. They are exchanging dollars for a token that is redeemable 1-for-1 and is meant to function as digital cash.

On prong three, the issuers argue that a reasonable holder of USDC is not expecting profit. The price is supposed to be $1 at all times, and any deviation is a bug, not a feature. There is no dividend, no yield, no claim on the issuer's equity. If the price drifts, the issuer's job is to arbitrage it back, not to grow the holder's stake.

On prong four, the issuer's efforts matter for the redemption and reserve process, but those efforts are aimed at keeping the token at par, not at generating returns for holders. The cases where Howey succeeded against token issuers, including the Terraform Labs ruling, involved explicit promises that the token's value would be supported by the issuer's active management of complex systems. Fiat-backed stablecoins lean heavily on the contrast.

That argument has not been fully tested in court for any major fiat-backed stablecoin. The SEC has not filed an enforcement action against Circle, Tether, or the issuer of PYUSD alleging that USDC, USDT, or PYUSD themselves are unregistered securities. Public statements from SEC officials have been inconsistent, and the agency's own 2023 and 2024 guidance documents have called stablecoins potential securities only in the most cautious language.

Where the picture changes: yield-bearing and algorithmic tokens

The argument gets weaker the moment a stablecoin starts producing yield. Ethena's USDe, for example, runs a delta-neutral strategy that earns funding rates from perp markets and distributes a portion back to holders. Sky's sUSDS, formerly sDAI, pays interest from on-chain lending markets. These products are closer to money-market funds than to dollar bills, and money-market funds have a long history of being treated as securities.

For these tokens, prong three looks much stronger. A reasonable buyer of USDe is expecting profit from the funding-rate strategy, not just a stable payment rail. Prong four also looks stronger, because the yield depends entirely on the issuer's protocol design, risk management, and treasury operations. If the manager changes strategy or makes a bad trade, the yield disappears, and so does the holder's expected profit.

Algorithmic stablecoins sit at the far end of this spectrum. The original Terra UST was designed to maintain its peg through a mint-and-burn relationship with the LUNA token, and the system was marketed as producing returns via staking and arbitrage. The SEC's complaint against Terraform Labs focused heavily on the marketing claims and the yield-bearing wrapper products, like the Anchor Protocol deposit account that advertised a fixed 20% APY. A federal jury found in 2024 that Terra's offerings were securities, even though the precise scope of the ruling is still being argued on appeal.

The takeaway is not that algorithmic stablecoins are always securities. It is that the more a stablecoin promises yield, the more it looks like a fund or a structured product, and the more cleanly it fits into the Howey prongs. The token's price being 'stable' is not the deciding factor. The deciding factor is whether the buyer is investing in an enterprise with the expectation of profit.

The real fight: which regulator, not which label

Even when the Howey test arguably fails, the regulatory picture is not over. The U.S. has multiple agencies with overlapping claims, and the turf fight is at least as important as the security question itself. State money-transmission regulators have claimed jurisdiction over stablecoin issuers for years, requiring licenses, audits, and capital floors. The OCC has occasionally granted national trust bank charters to crypto custody firms. The CFTC has claimed that stablecoins are commodities when used in derivatives markets.

This is why the term 'registered with the SEC' can be misleading. Some stablecoin issuers have registered investment products that hold stablecoin reserves, like certain money-market funds, with the SEC. That registration is about the fund wrapper, not about the stablecoin token itself. Other issuers have obtained money-transmitter licenses at the state level. Still others have pursued banking charters. None of those registrations is a clean statement that the token is or is not a security.

The GENIUS Act, proposed in 2024 and debated in various forms through 2025, is the most ambitious attempt to resolve the jurisdictional mess. The bill would create a federal license category for payment stablecoin issuers, set reserve and audit requirements, and explicitly preempt state licensing regimes for compliant issuers. Critically, it would also try to limit the SEC's ability to treat federally licensed payment stablecoins as securities.

Whether that preemption holds is the central legal question. The SEC has not formally conceded that a federally licensed payment stablecoin is not a security, and constitutional challenges to the preemption are likely. The bill also carves out yield-bearing stablecoins from the federal license, which means the harder Howey questions for products like USDe remain in regulatory limbo.

What this means for users and issuers

For a typical user holding USDC or USDT, the legal status of the token is not something you need to resolve yourself. You are not the one making the Howey argument. The risk you face is platform-level: an exchange delisting a token, a state regulator forcing a local issuer to wind down, or a federal action that freezes certain minting and redemption channels. Diversifying across issuers and using transparent, audited tokens is the practical hedge.

For developers and issuers, the calculus is structural. If you are launching a payment-focused stablecoin with full reserves and no yield, the GENIUS Act framework, if it passes, gives you a clear path. If you are launching a yield-bearing or synthetic-dollar product, expect continued regulatory uncertainty and consider whether the U.S. is the right market for the initial launch. Many of these products have explicitly chosen non-U.S. bases for that reason.

For anyone watching the space, the most useful habit is to read claims like 'X is a security' or 'Y is regulated' with the same skepticism you would apply to a project roadmap. The label usually describes a specific legal position, a specific product, or a specific jurisdiction. The headlines often blur all three, which is where confusion starts.

Follow the stablecoin regulatory story the smart way

Stablecoin classification shifts with court rulings, agency guidance, and legislation, and the news cycle is loud. Tracking which regulator just moved, which token got a new label, and which bill is advancing in Congress is a full-time job. Zippfeed surfaces stablecoin headlines with sentiment scoring (bullish, neutral, or bearish) and an importance rating, so you can tell the legal milestones from the noise.
