The UK’s long-promised cryptocurrency regulatory regime is moving closer to reality this week as the UK’s Financial Conduct Authority (FCA) published consultations that will ultimately define how cryptocurrency companies operate in the UK.
The proposals, together with HM Treasury legislation, form the backbone of a framework scheduled to come into force in October 2027. For policymakers, the goal is to balance growth and innovation with market integrity and consumer protection. For the industry, the challenge is to get through an 18-month transition period during which the goals are clearer than ever but still some way off.
“This is the situation in the UK,” Dea Markova, policy director at crypto infrastructure company Fireblocks, said in an interview. “This is the final regime for regulating the issuance and intermediation of crypto assets.”
From discussion to definition
Sébastien Ferrière, a financial regulation lawyer at Pinsent Masons, said the latest consultation needed to be seen as part of a longer, carefully sequenced process.
For more than a year, the UK has been working on a regulatory roadmap to expand the FCA’s jurisdiction over cryptocurrencies. The first step is legislation: Treasury defines regulated activities as determining which activities fall within the boundary. Only then can the FCA propose authorization requirements and detailed rules.
“Things have really started to take shape over the past year,” Ferrier said. “We have been consulting but now a coherent framework is emerging.”
The focus in the early stages will be on prudential requirements such as stablecoin issuance and custody, capital and taper plans, and the application of existing FCA obligations (governance, systems and controls, operational resilience) for cryptocurrency firms. This week’s consultations turn directly to the market: trading platforms, intermediaries, staking, decentralized finance, licensing and disclosure, and cryptocurrency-specific market abuse rules.
Overall, Ferrière said, the FCA is trying to transfer the traditional financial regulatory structure to the cryptocurrency market while adapting it to reflect the unique risks of the technology.
hybrid regulatory model
One of the most significant design choices was the UK’s decision to extend existing financial services rules to cryptocurrencies, rather than writing a separate rulebook from scratch as the European Union (EU) did with its regulation of markets in cryptoassets (MiCA).
This distinction is important, but not in a simplistic way. Ferrière described FCA’s approach as a hybrid one. Cross-cutting obligations – the principles of integrity, conflict management and fair treatment of clients – apply essentially as is. However, market-oriented rules are written specifically for cryptocurrencies.
“There is a new recognition and disclosure regime and a new market abuse regime,” Ferrier said. “They do not simply remove securities rules and apply them en masse. They echo existing frameworks, but they are drafted to reflect the parameters of crypto-assets and crypto-services.”
Regulators are walking a tightrope, he added. Being more lenient than traditional markets could lead to criticism that cryptocurrencies are receiving preferential treatment. Tighter restrictions could push activity overseas. The stated goal is “same risk, same outcome” even if the mechanics are different.
First-mover advantage and its limitations
For Markova, Britain’s most important asset is timing. By following the EU and taking part in the ongoing debate in the US, the UK has been able to observe the effects of regulatory decisions in practice.
“The UK is very actively trying to learn lessons from other jurisdictions,” she said. “You can see it in the proposals and the political narrative.”
Markova believes this statement is important because many of the decisions faced by banks and asset managers integrating crypto services end up being risk judgments in an area where the law is not black and white. A supportive policy context leads to different outcomes than one dominated by concerns about enforcement.
She also pointed to several areas where the UK differs from EU precedent, including a clear treatment of staking, lending and a more pragmatic recognition that cryptocurrency liquidity is global rather than tied to national venues.
unresolved pressure points
Despite the progress, significant uncertainty remains — especially when it comes to stablecoins and DeFi.
Regarding stablecoins, Markova said policymakers have acknowledged the need to distinguish between payments and investments and avoid the pitfall of regulating merchants as financial intermediaries just to accept digital tokens. But deeper questions remain unanswered: how foreign-issued stablecoins will be treated relative to sterling-denominated stablecoins, what due diligence obligations platforms will have, and how conservative settlement policies will impact adoption.
DeFi presents even more difficult conceptual challenges. The FCA has said that fully centralized activities will be regulated in the same way as traditional intermediaries. But many DeFi services are non-custodial by design.
“Identifying the responsible entity and applying a custody framework does not always address the actual risk,” Markova said. “That’s why DeFi regulation hasn’t really been addressed anywhere.”
Proportionality and global reach
David Heffron, a financial regulation lawyer at Pinsent Masons, defines the macro test as proportionality. The FCA insists it wants a competitive, innovative market but the cumulative burden of conduct rules, operational resilience standards and capital requirements will determine the UK’s attractiveness to global businesses.
“It’s too early to make a firm decision,” Heffron said. “But it’s an important market and I would be surprised if international operators didn’t want access to UK liquidity.”
Ferrier highlighted another issue that may become increasingly important: extraterritorial influence. In traditional finance, determining what constitutes “operating in the UK” is already complex. In the crypto space, which is global and digital in nature, companies may find themselves within the regulatory fold sooner than expected, forcing them to make decisions about geo-blocking, restructuring or establishing UK operations.
what success would look like
From the FCA’s perspective, success means better-informed investors, reduced market abuse, increased confidence and sustainable competition. New access and disclosure rules aim to standardize information about crypto-assets, while market abuse provisions aim to address manipulation and information asymmetries – both of which are prerequisites for deeper institutional engagement.
The cost is compliance, and the system is clearly not designed to eliminate risk. Instead, it seeks to ensure that participants participate in crypto markets with clearer information and stronger safeguards.
The UK has now crossed an important threshold: moving from endless “frameworks” to concrete regulatory end states. As the company decides whether to build for the UK’s cryptocurrency future before 2027, it will become clear whether its late-mover strategy will deliver a competitive advantage or simply delay clarity.
