What happened
The UK Treasury on Tuesday unveiled the long-trailed final shape of its crypto-asset regime, per Bitcoin Magazine's report Tuesday afternoon London time. The package pulls crypto firms, including exchanges, custodians, and certain stablecoin issuers, inside the regulatory perimeter of the Financial Conduct Authority and applies prudential standards modelled on the bank rulebook.
Firms will need to hold minimum capital against operational and counterparty risk, run periodic stress tests on their balance sheets, and submit to a market-abuse regime that mirrors the one governing UK equity venues. The Treasury also confirmed it has softened parts of the proposed stablecoin framework, including some of the strictest reserve and disclosure provisions that had drawn pushback during consultation.
The rulebook is the culmination of a process kicked off under the previous Conservative government and carried through by the current administration, with the stated aim of giving the UK a competitive edge over Brussels and Washington.
Why it matters
This is the moment the UK stops talking about being a global crypto hub and starts pricing the work. Until Tuesday, the country had a patchwork: anti-money-laundering registration with the FCA, a stablecoin consultation, scattered Treasury papers. Now there is a single rulebook firms can plan against.
The timing is deliberate. The EU's MiCA regime went fully live for crypto-asset service providers at the end of 2024, and the US GENIUS Act, signed into law in 2025, locked in a federal stablecoin framework that pulled issuers like Circle and Paypal deeper into the dollar orbit. London's pitch is that it can match the certainty of those regimes while running a lighter touch on parts of the stablecoin stack, particularly around reserve composition and disclosure cadence.
