Meet Dr. Marcus Hartmann
Dr. Marcus Hartmann has spent over two decades at the intersection of financial law and emerging technology. Based in Zug, Switzerland's Crypto Valley, he has guided exchanges, custodians, and institutional investors through licensing across the EU's MiCA regime, the US state and federal framework, and the UK's evolving FCA rules.
He advises founders on where to base a crypto business, weighing the unified single market of MiCA against the fragmented but deep US market and the phased UK regime, and coordinates applications across more than 60 jurisdictions.
In 2026 the EU regulates crypto through one unified rulebook, MiCA, fully applicable since December 2024 and offering a single passport across 27 member states. The US stays fragmented across the SEC, the CFTC, and state regulators, with the GENIUS Act of July 2025 the first federal crypto law. The UK is phasing in an FCA regime built on FSMA 2023, with full authorisation expected from October 2027.
- The EU's MiCA is the most comprehensive single framework, fully applicable since 30 December 2024, with passporting across all 27 member states
- The US is fragmented: the SEC, the CFTC, FinCEN, and individual states each play a role, with no single federal crypto licence
- The GENIUS Act, signed 18 July 2025, gave the US its first federal stablecoin framework; broader market-structure rules are still pending in the Senate
- The UK runs a phased FCA regime under FSMA 2023, with a financial-promotions rule already in force and full authorisation expected from 25 October 2027
- The right regime depends on your model and target market; passporting, securities risk, and timing pull in different directions
Three Markets, Three Approaches
Crypto regulation is no longer a blank page in any of the three largest Western markets, but the way each has filled that page could hardly be more different. The European Union built a single, prescriptive rulebook from scratch. The United States layered new federal law on top of an existing patchwork of agencies and state regimes. The United Kingdom chose a phased path, folding crypto into its mainstream financial-services framework over several years. If you want the foundations first, our explainer on what crypto regulation is and why it matters sets the scene.
For a founder, the distinction is not academic. It decides how many licences you need, which regulator can sanction you, how much capital you must hold, and how quickly you can serve customers. A business that passports across the EU under one MiCA authorisation faces a very different operating reality from one stitching together state money-transmitter licences in the US, or one waiting for a UK regime that is still phasing in.
This guide compares the three regimes on the points that matter most for licensing: the legal framework, the regulators, how stablecoins are treated, the current status, and what each means for retail access. None of the three is simply "better." Each carries trade-offs, and the right choice depends on where your customers are and what you intend to offer.

USA vs EU vs UK at a Glance
The table below distils the three regimes onto the dimensions founders ask about most: the governing framework, the lead regulator, how stablecoins are handled, the current legal status, and the position on retail access. Treat it as a map, not the territory, because the detail within each cell can fill a chapter on its own.
| Dimension | USA | EU | UK |
|---|---|---|---|
| Framework | Fragmented; GENIUS Act (stablecoins) + securities & commodities law | MiCA, single unified rulebook | FSMA 2023 + phased FCA regime |
| Lead regulator | SEC, CFTC, FinCEN + state regulators | National authorities under ESMA / EBA coordination | Financial Conduct Authority (FCA) |
| Stablecoins | GENIUS Act: 100% reserves, monthly disclosure | MiCA: ART & EMT rules (from June 2024) | Being brought into phased FCA regime |
| Status | Stablecoin law live; market-structure bill pending in Senate | Fully applicable since 30 Dec 2024; transition to mid-2026 | Promotions rule live; full regime planned for Oct 2027 |
| Retail access | Permitted, varies by state and asset classification | Permitted under authorised CASPs, single market | Permitted with strict financial-promotion rules |
Summary based on official EU, US, and UK sources current to 2026. Always confirm against your specific licensing jurisdiction.
The EU: MiCA, One Rulebook
The European Union took the boldest structural step of the three. The Markets in Crypto-Assets Regulation, known as MiCA, is a single piece of EU law that governs token issuance, stablecoins, and crypto-asset service providers across all 27 member states. Its stablecoin provisions for asset-referenced and e-money tokens applied from 30 June 2024, and the full regime for crypto-asset service providers became applicable on 30 December 2024. For a deeper walkthrough, see our dedicated guide on MiCA explained, and our EU regulation overview for the wider context.
The headline advantage is passporting. A firm authorised as a crypto-asset service provider, or CASP, in one member state can offer its services across the entire EU single market without a separate licence in each country. For a business targeting European customers, this turns 27 national regimes into one addressable market, which is a powerful reason to base operations inside the bloc.
The trade-off is rigour. MiCA imposes detailed governance, prudential, custody, conflict-of-interest, and disclosure requirements, and existing firms must transition into the regime. The grandfathering window lets businesses operating under national law before 30 December 2024 continue until 1 July 2026 or until they are authorised or refused, but member states may shorten or opt out of that period, and several chose a tighter timeline. Founders should confirm the exact deadline in their chosen country rather than assuming the full window applies.
The USA: SEC, CFTC and the GENIUS Act
The United States is the largest crypto market and the most fragmented regulator of the three. There is no single federal crypto statute covering the whole sector. Instead, oversight is split: the Securities and Exchange Commission (SEC) regulates assets it deems securities, the Commodity Futures Trading Commission (CFTC) oversees commodities and derivatives, FinCEN handles anti-money laundering, and individual states add their own licensing, the New York BitLicense being the best-known example. Our US regulation overview maps this landscape in more detail.
The defining federal development came on 18 July 2025, when the GENIUS Act was signed into law, the first major US federal crypto statute. It creates a framework for payment stablecoins, requiring issuers to hold 100 percent reserves in liquid assets such as US dollars or short-term Treasuries, publish monthly disclosures of those reserves, and follow strict marketing rules. Notably, the Act excludes compliant payment stablecoins from the federal definitions of "security" and "commodity," carving them out of the SEC and CFTC overlap.
Broader market-structure legislation, commonly referenced as the CLARITY Act, would divide jurisdiction more cleanly, giving the CFTC authority over digital commodity spot markets and the SEC authority over investment-contract assets. It passed the House of Representatives in 2025 but, as of 2026, awaits action in the Senate and is not yet law. Until it passes, the SEC and CFTC boundary remains the central uncertainty for US crypto firms, and licensing typically means combining FinCEN registration with state money-transmitter licences.
"Founders often assume the US is one market with one rulebook. It is not. You can be compliant with FinCEN, hold money-transmitter licences in forty states, and still face an SEC view that your token is a security. The fragmentation is the cost of entry, and it is why many EU-facing businesses start with a MiCA licence instead."

Get Free Consultation →The UK: A Phased FCA Regime
The United Kingdom chose neither the EU's big-bang single rulebook nor the US's agency patchwork. Instead, it is folding crypto into its existing financial-services architecture in phases. The Financial Services and Markets Act 2023 (FSMA 2023) brought cryptoassets within the remit of the Financial Conduct Authority (FCA), and the FCA published a cryptoasset roadmap in November 2024 setting out a multi-phase plan to bring crypto activities into the mainstream regime. Our UK regulation overview tracks the detail as it develops.
One piece is already live: the financial-promotions regime, in force since October 2023, which governs how crypto can be marketed to UK consumers and is among the strictest such regimes anywhere. On top of that, the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were made by Parliament in February 2026, setting the legislative foundation for full authorisation.
The full authorisation regime is being introduced gradually. The FCA plans to open a pre-application support service in July 2026 and run an application window from late September 2026, with the main regime expected to come into force on 25 October 2027. For founders, that means the UK is a market in transition: the promotions rules bind now, but the comprehensive authorisation framework is still arriving, so timing is a genuine planning factor.
In our licensing work, the EU-versus-US-versus-UK question almost never has a single right answer, and the worst outcomes come from founders who pick a jurisdiction before they have defined their customer base. We routinely see businesses chase a US presence for prestige, only to discover that state-by-state money-transmitter licensing and unresolved securities risk make the launch far slower and costlier than a MiCA route would have been for the same European customer base.
Equally, we see firms assume the UK is open for full authorisation today when, in practice, the comprehensive regime is still phasing in toward 2027 while the promotions rules already bite. Mapping the live obligations against the planned ones, and matching them to where the revenue actually sits, is the single most valuable step before any application. We do that mapping before a client commits a euro to incorporation.
Stablecoins: Three Models
Stablecoins are where the three regimes have moved fastest and where the contrast is clearest. The EU regulates them under MiCA as asset-referenced tokens and e-money tokens, with rules that applied from 30 June 2024, imposing reserve, redemption, and issuer requirements and capping the use of large non-euro stablecoins as everyday means of payment. The framework sits inside the single MiCA rulebook rather than standing apart.
The US took a focused legislative route. The GENIUS Act of July 2025 created a dedicated federal framework for payment stablecoins, mandating full reserve backing in liquid assets, monthly public disclosures, and the technical ability for issuers to freeze or seize tokens under lawful order. It is narrower than MiCA, addressing stablecoins specifically rather than the whole crypto sector, but it is now settled federal law.
The UK is bringing stablecoins into its phased FCA regime alongside other cryptoassets, rather than legislating for them in isolation. The result is three distinct models for the same instrument: a comprehensive EU rulebook, a targeted US statute, and a phased UK integration. A stablecoin issuer serving all three markets must satisfy all three, which is a recurring theme in cross-border licensing engagements.
Why this matters for licensing: a project that intends to issue or distribute a stablecoin should treat regime choice as a primary decision, not a detail. The reserve, disclosure, and redemption obligations differ materially between MiCA and the GENIUS Act, and the UK position is still settling. Pin down which framework governs your token before you build the product, not after.
How to Choose Between Them
Choosing between the three regimes is a structured decision, not a preference. The timeline below sets out the sequence we use with clients, anchored to the real regulatory milestones that shape each market. The detail varies by business model, but the order of questions is consistent: define the customer, map the regime, then commit.
UK dates are planned and may move; confirm against current FCA guidance before relying on them.
