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. 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:

  • 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.
