UK Finalizes Crypto Rules — Mandatory Framework Takes Effect October 2027

After months of back and forth with the industry, the United Kingdom (UK) has finalized how it plans to regulate crypto, with the Financial Conduct Authority (FCA) confirming that trading platforms, custodians, and stablecoin issuers will fall under a new mandatory framework starting October 2027.

Crypto Regulation In The UK Just Got Friendlier 

According to the Financial Times, crypto firms had complained that the FCA’s initial draft was too restrictive and risked leaving the UK behind in a market that other countries were moving on quickly — the US among them, where the Trump administration and Congress have spent the past year building out a new regulatory framework for the sector.

As such, smaller companies and those engaged in lower-risk activities will no longer be required to publicly disclose their capital requirements — a blanket rule the FCA has now dropped entirely.

The regulator believes the softer approach will pay off in adoption. The FCA estimates the new rules could bring “three to four million additional customers” into UK crypto markets simply by giving people more confidence to participate. 

David Geale, the FCA’s executive director for payments and digital finance, framed the shift as foundational rather than restrictive. “This is about giving crypto a solid foundation from which to build,” he said, adding that the new regime represents “the biggest change in the FCA scope for at least a decade.” 

Stablecoin Rules Are Final 

Stablecoins will also fall under joint oversight from the FCA and the Bank of England. The central bank had already signaled its own softening last week, dropping several of its more unpopular proposals for stablecoin issuers. The FCA followed suit on Monday, cutting the extra capital requirement for issuers of non-systemic stablecoins in half, from 2% of total issuance down to 1%. 

Companies holding crypto tokens within their trading books will need capital covering 40% of their net exposure — a meaningful reduction from an earlier proposal that would have demanded a full 100% capital requirement for some riskier tokens.

Geale was direct about why the numbers moved. “We have listened to what works and we’ve listened to what doesn’t work,” he said. “We got feedback on capital that we were starting a bit high.” 

Beyond capital requirements, the FCA also relaxed its rules around liquidity, intragroup custody arrangements, and pre-trade transparency obligations for crypto firms.

One area still being worked out is decentralized finance (DeFi). The FCA said it plans to consult later this year on guidance specifically for that sector. Matthew Long, the FCA’s director of payments and digital assets, acknowledged the difficulty of regulating something designed to avoid centralized control. 

“An awful lot of discussions around DeFi do end up with an element of centralized finance,” Long said, explaining that the new rules will apply wherever there is an identifiable controlling entity that regulators can actually hold accountable.
