Who regulates cryptocurrency in the US?

Multiple agencies have overlapping jurisdiction. The SEC (Securities and Exchange Commission) claims authority over tokens that qualify as securities. The CFTC (Commodity Futures Trading Commission) regulates crypto derivatives and has asserted Bitcoin and Ethereum are commodities. FinCEN (Financial Crimes Enforcement Network) oversees AML compliance for crypto businesses. The IRS handles crypto taxation.

MiCA (Markets in Crypto-Assets Regulation) is the EU's comprehensive crypto regulatory framework, effective from 2024. It covers crypto asset issuers, crypto asset service providers (exchanges, wallets, custodians), stablecoin issuers, and DeFi is partially excluded. MiCA creates a single licensing regime allowing an approved entity to operate across all 27 EU member states.

Why does regulatory clarity matter so much for crypto?

Unclear regulation creates compliance risk for businesses, which often respond by exiting jurisdictions or restricting services. US users, for example, lost access to many tokens and features during the 2023–2025 SEC enforcement wave. Regulatory clarity also enables institutional investment — many traditional funds cannot invest in assets with uncertain legal status.

DeFi is largely unregulated but increasingly targeted. The CFTC has taken action against DeFi protocols for offering unregistered derivatives. The EU's MiCA initially excludes 'fully decentralised' protocols but requires the European Commission to assess DeFi by 2025. Regulatory approaches to DeFi are still being developed globally.

How Cryptocurrency Regulation Works

Crypto regulation is complex, fragmented, and rapidly evolving. This article maps the agencies, frameworks, and jurisdictions that matter most.

Why crypto gets regulated

Governments regulate crypto for several overlapping reasons: preventing money laundering and terrorist financing (AML/CFT), collecting taxes on capital gains, protecting retail consumers from fraud and scams, maintaining financial stability (particularly concerning stablecoins), and asserting monetary sovereignty. Different regulators emphasise different motivations, which is why approaches vary so much.

Crucially, crypto regulation does not necessarily mean banning crypto. The vast majority of jurisdictions — including the US, EU, UK, and most developed economies — have chosen to regulate rather than prohibit.

US regulatory agencies

The US has no single crypto regulator, creating a patchwork of overlapping jurisdiction:

SEC: Asserts jurisdiction over tokens that are securities under the Howey Test. Has sued multiple exchanges and token issuers.
CFTC: Regulates crypto futures and derivatives. Views Bitcoin and Ethereum as commodities, not securities.
FinCEN: Requires crypto businesses to register as Money Services Businesses (MSBs) and comply with Bank Secrecy Act (BSA) AML rules.
IRS: Treats crypto as property. Capital gains tax applies to crypto disposals (sales, trades, payments).
OCC / Fed / FDIC: Regulate bank interactions with crypto; the ability of banks to custody crypto, hold reserves, etc.

MiCA: Europe's framework

The EU's MiCA regulation is the most comprehensive crypto regulatory framework globally. It establishes:

Licensing requirements for Crypto Asset Service Providers (exchanges, custodians, advisors)
White paper requirements for token issuers (similar to prospectus requirements for securities)
Strict reserve and redemption requirements for stablecoin issuers (EMTs and ARTs)
Passporting — one EU license allows operation across all 27 member states

MiCA does not cover NFTs (yet), DeFi (partially excluded), or central bank digital currencies (CBDCs). These are being addressed in subsequent legislation.

Global overview

European Union	MiCA — the world's first comprehensive crypto framework. Covers CAPs, CASPs, stablecoins. Effective 2024. Passporting across 27 member states.
United Kingdom	FCA-led. Crypto exchanges must register. Stablecoins regulated under the Financial Services and Markets Act 2023. Working towards broader regime.
Singapore	MAS-supervised. Payment Services Act licenses crypto businesses. Clear framework with reputation for regulatory pragmatism.
UAE / Dubai	VARA (Virtual Assets Regulatory Authority) in Dubai. Aggressive licensing to attract global crypto businesses. One of the most business-friendly major jurisdictions.
