FCA Opens Crypto Rules to Global Trading, but Questions Remain

The FCA is taking a model that could connect foreign exchanges and stablecoins to global liquidity. But licensing, AML checks, and the line with MiCA are still unclear.

Key Takeaways

• The UK FCA rolled out new crypto rules that are meant to preserve global liquidity and keep non-UK stablecoins circulating.
• Foreign crypto exchanges can serve UK customers through locally authorized entities, but they first need FCA authorization.
• Market players see a chance for London to become a crypto hub, but they doubt how fast and predictable the licensing process will be.

The UK’s FCA introduced its new crypto framework this week, and the market’s first read is mostly positive. The rules are designed to keep global liquidity intact and allow non-UK stablecoins to continue circulating. Even so, the bigger question is whether the UK can move quickly and consistently enough to turn that framework into a real advantage for London as an international crypto hub.

Global Liquidity Takes Center Stage

At the heart of the proposal is a simple idea: foreign crypto exchanges should be able to reach UK customers through locally authorized entities without losing access to the broader international trading system. The FCA is trying to avoid a situation where trading gets boxed into a narrow UK-only liquidity pool, which supporters argue could hurt pricing and reduce value for customers.

That stance is notably different from MiCA in the European Union, which several market participants say puts more weight on clearly defined European operations and liquidity. For crypto firms that already operate across borders, that distinction matters. The FCA appears to be choosing a model that keeps cross-border market structures more open instead of drawing a hard line around them.

The new framework is not limited to trading. It also lays out prudential standards, conduct rules, market integrity requirements, and separate rules for stablecoin issuers. For activities such as trading, custody, intermediation, and staking, firms will need FCA authorization before the regime starts on October 25, 2027.

Licensing Is Still the Biggest Hurdle

Still, approval is likely to be a difficult lift. Lawyers and market participants say the authorization process could be demanding, in part because the FCA has not yet said which foreign jurisdictions it will treat as sufficiently comparable on oversight and investor protection.

That uncertainty is a real problem for firms trying to plan ahead. Without knowing which markets will qualify, it becomes much harder to commit capital, hire staff, and build out compliance systems on a workable timeline.

The FCA also has a tough reputation when it comes to AML registrations, with more than 85 percent of applications either rejected or withdrawn. This new regime goes further than that and also includes Consumer Duty, capital requirements, operational resilience, and senior management accountability.

What This Means for Europe

For European crypto watchers, the main point is that London is trying to position itself as a practical alternative to MiCA. The UK rules are also meant to cover meaningful UK-facing activity, even when the company is based elsewhere. That could force international platforms to rethink how they structure their European operations.

DeFi remains an open question as well. The FCA appears to be aiming for a more nuanced approach to genuinely decentralized systems, while central intermediaries are still clearly within scope under the new rules. That distinction matters for institutional players, who need legal certainty and governance standards before blockchain infrastructure can be used more widely in traditional finance.

The UK’s approach also fits into a broader global shift, with regulators paying closer attention to legal clarity around digital assets. In the US, that same debate is unfolding around legal clarity for tokenized assets, where the key issue is which rules apply to ownership, settlement, and oversight.
