Cryptocurrency regulation in the United States is divided among several authorities rather than controlled exclusively by one agency. The Securities and Exchange Commission and Commodity Futures Trading Commission have different statutory responsibilities, with oversight depending heavily on how an asset, transaction or financial product is classified.

SEC Oversees Securities

The SEC administers federal securities laws. Its authority applies when crypto-related activities involve securities, including transactions structured as investment contracts.

In March 2026, the SEC issued an interpretation explaining how federal securities laws apply to crypto assets and transactions. It established a taxonomy covering categories including digital commodities, digital collectibles, digital tools, payment stablecoins and digital securities. The CFTC simultaneously provided guidance explaining that it would administer the Commodity Exchange Act consistently with the SEC interpretation.

Importantly, a crypto asset that is not itself a security can still be involved in an investment contract depending on how it is offered and the surrounding circumstances. 

In August, the SEC also proposed Regulation Crypto Assets, which would establish a tailored securities-offering framework for certain investment contracts involving crypto assets. The proposal has not itself replaced existing federal law. 

The CFTC Oversees Commodity Derivatives

The CFTC’s established authority includes derivatives markets involving commodities, including futures, options and swaps tied to digital commodities.

Spot markets are more complicated as the CFTC does not have the same comprehensive regulatory framework for ordinary spot commodity trading that it has over derivatives.

In September 2025, SEC and CFTC staff clarified that SEC- and CFTC-registered exchanges are not prohibited from facilitating certain spot crypto commodity products. However, the statement itself did not change existing law or create new obligations. 

The CFTC continued updating its crypto guidance in September 2026. On September 24, staff revised FAQs covering matters including tokenized permitted investments and blockchain-based recordkeeping for registered market participants. 

Congress has Not Finalized a Broader Framework

Congress has considered legislation intended to create clearer statutory boundaries for digital-asset regulation.

On September 15, the Senate failed to advance the CLARITY Act, with the procedural vote receiving a 49-50 majority but falling short of the 60 votes required to proceed. Four Republican senators joined Democrats in opposing advancement. Senator Thom Tillis moved to reconsider the vote, preserving the possibility that the measure could be reconsidered. 

For now, this leaves the SEC and CFTC operating largely through their existing statutory authorities rather than a newly enacted comprehensive crypto market-structure law.

Classification Determines Oversight

The key regulatory question is therefore not simply whether cryptocurrency belongs to the SEC or CFTC.

A digital security or transaction involving an investment contract can fall under securities laws, while derivatives involving digital commodities fall within the CFTC’s established jurisdiction. 

Stablecoins, banking activities, anti-money-laundering requirements and state licensing can bring additional regulators into the picture.

The SEC added further clarification on September 25 through staff FAQs addressing its March crypto interpretation. The agency specifically notes that these FAQs represent staff views and have no legal force or effect. 

Final Thoughts

US cryptocurrency regulation remains divided between the SEC, CFTC and other authorities. Recent guidance has clarified some boundaries, but it does not replace legislation establishing a comprehensive market structure. Future congressional action could further define how responsibilities are divided.

FAQs:

1. Does the SEC or CFTC regulate cryptocurrency in the US?

Both agencies have roles. The SEC administers securities laws, while the CFTC regulates commodity derivatives and has authority under the Commodity Exchange Act within its statutory jurisdiction. 

2. When does cryptocurrency fall under SEC oversight?

SEC oversight can apply when a crypto asset is a security or a transaction involves an investment contract. The SEC issued a detailed interpretation of these classifications in March 2026. 

3. What cryptocurrency activities does the CFTC regulate?

The CFTC regulates derivatives involving digital commodities, including relevant futures, options and swaps. Its authority over ordinary spot commodity markets differs from its comprehensive derivatives oversight.

4. What is the SEC’s Regulation Crypto Assets proposal?

Proposed in August 2026, Regulation Crypto Assets would establish tailored offering exemptions and other rules for certain investment contracts involving crypto assets. The proposal is not yet a final rule. 

5. Why does crypto classification matter for regulation?

Classification can determine which federal laws and regulatory requirements apply to an asset, transaction or market participant. It can affect areas such as registration, disclosures, trading and compliance obligations.
