The FCA named Revolut, Monee, ReStabilise and VVTX to test stablecoin services in its regulatory sandbox, with Revolut still chasing the banking licence it first sought in 2021.

Key takeaway

Revolut won a slot to test stablecoins inside FCA rules still being written, not guessing at unpublished ones.

The Financial Conduct Authority (FCA) selected four firms to test stablecoin services in its regulatory sandbox, naming Revolut, Monee, ReStabilise and VVTX⁠1. Revolut is the headline: Britain's most-valued private fintech at roughly $45bn, still chasing the full UK banking licence it first sought in 2021.

A regulatory sandbox lets a firm trial a product under FCA supervision before the rules around it are finalised. For a stablecoin issuer, that supervision is the whole point, because the UK framework for fiat-backed tokens is being drafted now rather than settled.

The regulator also opened a second cohort of its AI Lab, eight firms testing AI tools with access to Nvidia compute and FCA data, following the first AI Live Testing intake in April. The posture is consistent with the FCA's drive to thin the rulebook, having cut Senior Managers and Certification Regime roles by 15% in the spring. For a fintech founder, a sandbox slot is the difference between building toward an unwritten rule and testing inside one the regulator is writing alongside you.

Deep Analysis

In plain English

A stablecoin is a type of digital currency whose value is fixed to a real currency, like the pound sterling. Unlike Bitcoin, which swings wildly in value, a stablecoin always trades at £1. They are used for instant payments, transfers and as a building block for financial applications that run on public computer networks. The UK's Financial Conduct Authority (FCA) runs a regulatory sandbox, an environment where companies can test products under supervision before the full legal framework is in place. On 8 June 2026, the FCA selected Revolut and three other firms to test stablecoin services in that sandbox. Revolut, the UK's largest fintech by valuation at roughly $45bn, is the most prominent selection. Getting into the sandbox is the first step toward full FCA authorisation to issue a stablecoin commercially in the UK.

What could happen next?
  • Opportunity

    Revolut's sandbox entry gives it 18-24 months of supervised transaction data before the final FCA stablecoin authorisation regime is live, a first-mover advantage in sterling digital payments that smaller fintech competitors cannot replicate on the same timeline.

  • Risk

    The FCA's 28-month average sandbox-to-authorisation timeline (from the 2017-19 PSD2 precedent) means the UK stablecoin regime may not be commercially live until mid-2028, after MiCA-authorised EU issuers have established network effects in digital euro and digital pound-adjacent products.

  • Meaning

    The FCA AI Lab second cohort, using NVIDIA compute and FCA live data, continues the regulator's shift from reactive rule-enforcement toward active participation in the supervised testing of technologies that will reshape UK financial services.

Different Perspectives
Nscale and Open Cosmos
Nscale and Open Cosmos
Nscale chose the New York Stock Exchange for its listing on 18 September, putting Britain's largest AI infrastructure bet to American public investors rather than British ones. Open Cosmos took the opposite route four days earlier, raising nine figures from an all-domestic syndicate on five years of profit, evidence that staying is possible when the balance sheet allows it.

Committee chair Dame Chi Onwurah wrote to government on 7 September asking how Matt Clifford's conflict at ARIA arose and what safeguards protect its governance, and expects a detailed response. Her question has not yet been put to the Sovereign AI Unit, whose own chair sits at a venture capital firm while overseeing state AI equity.
The Entrepreneurs Network
The Entrepreneurs Network
The Entrepreneurs Network's founder survey found 65% say Britain is easy to start a business in but only 14% say it is easy to scale one, with 82% negative on tax and 74% finding investment hard to access. On this reading the constraint is regulation and tax, not the capital-vehicle design the state keeps adjusting.
New Economics Foundation
New Economics Foundation
The New Economics Foundation argues fiscal accounting rules, not political will, cap what Britain's state capital vehicles can do. Matching the KfW and Bpifrance benchmark of 1% of GDP would need the National Wealth Fund to deploy roughly GBP21bn a year by 2028-29, about four times its current capacity.

The CMA's 8 September report on public procurement asked whether Britain's roughly GBP400bn state-spending system is built to grow high-potential firms rather than simply widen SME participation. Its Recommendation 5 calls for a dedicated frontier-technology procurement framework, an official acknowledgement that today's design may serve the wrong target.

Highland Europe, the growth-equity firm behind a €1bn-plus fund, took €65m from the British Business Bank into its Technology Growth Fund VI on 30 July via British Patient Capital. For a Geneva-based growth investor, the Bank's cheque is routine cornerstone capital, unrelated to which Whitehall department currently claims to sponsor UKRI.
