Firms will have to be authorized by the FCA — with the regime due to take effect in late 2027 — bringing the UK into line with the EU and adding to a global wave of crypto rulemaking. The UK has put crypto on the same footing as the rest of finance. The **Financial Conduct Authority (FCA)** — Britain's main financial regulator — has laid out a comprehensive framework requiring crypto firms to become **FCA-authorized**, bringing exchanges, custodians, dealers and stablecoin issuers inside the regulatory net for the first time, [the FCA said](https://www.fca.org.uk/firms/new-regime-cryptoasset-regulation). The new regime is set to **take effect in late 2027**, with firms expected to apply for authorization in a window running from late 2026 into early 2027. ## What the rules require The point of the framework is to subject crypto firms to the kinds of obligations that have governed banks and brokers for decades, [as The Block detailed](https://www.theblock.co/post/406546/uk-sets-capital-market-abuse-rules-landmark-crypto-framework): - **Capital requirements** — firms must hold a financial cushion scaled to their risk and activity (stablecoin issuers, for instance, face a capital charge tied to the value they handle). - **Custody rules** — companies safekeeping customers' crypto must do so to standards akin to traditional asset custodians, with a threshold that treats firms holding client assets during settlement as regulated custodians. - **Market-abuse rules** — prohibitions on insider dealing and manipulation, mirroring the integrity rules that apply to stock markets. - **Consumer protection** — disclosure and conduct standards, plus recourse if something goes wrong. (Exact thresholds and dates run through detailed FCA rules; treat the finer figures as subject to the regulator's final text.) ## Why now The logic is the lesson of the last cycle. The crypto **boom and bust** — the 2021 mania, then the 2022-23 implosions, most spectacularly **FTX** — showed the cost of leaving the sector largely outside the rules. Like a growing list of governments, the UK has concluded the answer is **regulation, not prohibition**: bring crypto inside the perimeter, protect consumers, police manipulation, and give legitimate firms legal certainty. Britain is also competing to be a **crypto hub**, and credible rules are part of that pitch. ## The global picture This is the local edition of a worldwide trend Boursel has tracked. The **EU's MiCA** regime has been in force since the end of 2024, giving Europe a head start. The **United States** went narrower, passing the **GENIUS Act** in 2025 to regulate **stablecoins** specifically (requiring full reserve backing and disclosures) while leaving other crypto activity to a patchwork of agencies. The UK's approach is closer to the EU's in breadth, folding crypto into its existing **financial-services law** rather than building a separate rulebook. The throughline everywhere: crypto is moving from the fringe into **regulated finance**. ## What it means For **crypto firms**, the rules bring legitimacy but also **cost**. Authorization, capital buffers and compliance are expensive, and smaller players may struggle to afford them — which could **consolidate** the UK market around larger, better-capitalized firms (a pattern MiCA has already shown in Europe). For **consumers**, the upside is concrete: regulated custody of their assets, capital behind the firms they use, and a regulator to complain to. The bet the UK is making is the same one regulators everywhere are making: that **clear, credible rules** will draw serious money and serious firms while pushing out the cowboys. Whether it works depends on enforcement once the regime goes live — but the direction is now set. After years of treating crypto as a thing apart, Britain has decided it's just another part of the financial system that needs watching. ## Sources - [A new regime for cryptoasset regulation](https://www.fca.org.uk/firms/new-regime-cryptoasset-regulation) - [UK sets capital, market-abuse rules in landmark crypto framework](https://www.theblock.co/post/406546/uk-sets-capital-market-abuse-rules-landmark-crypto-framework)
