FCA tests four firms in sandbox

In a move to advance the regulation of uk stablecoins, the Financial Conduct Authority has selected a first cohort of firms to test new services in its Regulatory Sandbox.

Four firms chosen to trial stablecoin services

The FCA has picked 4 companies to test how their stablecoin services operate under proposed rules in a controlled environment. Moreover, the watchdog aims to balance innovation with consumer protection as activity in digital assets accelerates.

This first stablecoins cohort reflects the FCA’s commitment to supporting growth and innovation in UK financial services. A total of 20 applications were received, and the regulator selected Monee Financial Technologies, ReStabilise, Revolut and VVTX for participation.

Regulatory Sandbox framework and objectives

The Regulatory Sandbox programme allows firms to pilot stablecoin products in real world conditions with appropriate safeguards. However, these trials will take place under close supervision to ensure risks are contained while innovation is encouraged.

The initiative will help the FCA assess its proposed policy in a live environment and refine future rules so they are clear, effective and supportive of responsible innovation. That said, the regulator is also using the Sandbox to gather detailed operational data on different business models.

Focus on issuance and range of use cases

The FCA’s testing will primarily centre on stablecoin issuance. The 4 selected firms put forward proposals spanning a range of use cases, including payments, wholesale settlement and crypto trading, giving supervisors visibility across multiple segments of the market.

Within this framework, the regulator is effectively conducting stablecoin issuance testing while monitoring how tokens are integrated into payment flows and trading venues. Moreover, each firm will receive feedback from FCA specialists as they help shape the UK’s long-term regulatory approach.

Official comments and policy context

Matthew Long, director of payments and digital assets at the FCA, underlined the strategic importance of the project. He said the authority is backing UK stablecoin issuers to make sure these assets can be trusted for payments, settlement and trading across the financial system.

According to Long, this work will benefit consumers and financial transactions while helping deliver the FCA’s strategy and the Government’s National Payments Vision. However, he also signalled that safeguards remain essential as stable-value tokens become embedded in everyday finance.

Link with broader UK crypto regulatory agenda

The testing programme is part of the FCA’s broader efforts to enable innovation across UK financial services. It complements other initiatives such as the Digital Securities Sandbox (DSS), which explores how tokenised securities interact with existing market structures and regulations.

Testing begins in Q1 2026, and the findings will help shape the UK’s final stablecoin rules later in 2026. Moreover, these results will feed into the wider uk crypto regulation timeline as the country moves towards a comprehensive framework for digital assets.

Consultations and cryptoasset policy development

The FCA has already received 20 applications from firms seeking to test stablecoins in its Regulatory Sandbox. In parallel, the authority has published its crypto roadmap setting out the expected timeline for future crypto regulation and supervisory milestones.

Over recent months, the regulator has consulted on key topics such as stablecoin issuance and cryptoasset custody consultation (CP25/14), prudential rules (CP25/15 and CP25/42), application of the FCA Handbook (CP25/25 and CP26/4), conduct of business and high-level standards (CP25/40), and admissions, disclosures and market abuse (CP25/41).

The consultations on the future regulatory regime for cryptoassets are now substantively complete, and the FCA plans to publish its Policy Statements in the summer. However, firms are being urged not to wait for final documents before starting their implementation planning and internal reviews.

Authorisation requirements and timeline

All firms will need to be authorised under the new regime once it goes live in October 2027. The application gateway for companies wishing to carry out crypto activities in the UK opens in September 2026, and now is the time for potential applicants to begin preparing submissions.

To support the market, the FCA is hosting authorisation-focused webinars to help prospective applicants understand its expectations. The first webinar is already available on demand, while the next session on 18 March will focus on the FCA’s anti-money laundering rules and compliance obligations.

Coordination with the Prudential Regulation Authority

The Prudential Regulation Authority (PRA) has also weighed in on these developments. It issued a Dear CEO letter regarding innovations in the use by deposit-takers of deposits, e-money and regulated stablecoins, highlighting prudential and operational risk considerations.

That said, the PRA’s letter aligns with the Sandbox initiative by emphasising that new models using stable-value instruments must be robust, well governed and properly capitalised. Moreover, the joint focus underscores how both regulators are coordinating their approach to digital money and tokenisation.

Role of the FCA in the evolving market

The FCA states that it enables a fair and thriving financial services market for the benefit of consumers and the wider economy. It is also inviting firms to learn more about existing rules they must already comply with, even as new crypto-specific regulations are finalised.

As activity around uk stablecoins expands, the Sandbox trials with Monee Financial Technologies, ReStabilise, Revolut and VVTX will provide crucial insights. In summary, these pilots are set to guide the UK’s final stablecoin rulebook in 2026 and shape authorisation standards for years to come.
