FCA Selects 4 Firms to Test Stablecoin Innovation in Its Regulatory Sandbox

WHY THIS MATTERS: The FCA’s launch of a dedicated Regulatory Sandbox for stablecoins is a pivotal moment in the UK’s quest to become a global hub for digital asset regulation. This move signals that the UK is not merely reacting to decentralized finance innovation, but is actively engineering a robust and trusted framework for fiat-backed digital currencies. The selection of four diverse firms, including retail giant Revolut and wholesale specialists, demonstrates a pragmatic approach to tackling the full spectrum of stablecoin use cases, from consumer payments to institutional wholesale settlement. By focusing on stablecoin issuance in a live environment, the FCA is laying the foundation for a ‘gold standard’ of trust, ensuring these digital instruments can be reliably used across commerce and finance. This value-first initiative is critical, as clear, effective rules are the single biggest factor that will unlock serious institutional adoption and help deliver the UK Government’s National Payments Vision.

The Financial Conduct Authority (FCA) has chosen 4 companies, Monee Financial Technologies, ReStabilise, Revolut and VVTX, to test how their stablecoin services work with proposed regulation in a safe environment. 

The Regulatory Sandbox programme allows firms to trial stablecoin products in real world conditions with appropriate safeguards. It will help the FCA assess its proposed policy in a live environment and ensure future rules are clear, effective and support responsible innovation.  

The FCA’s testing will primarily focus on stablecoin issuance. The four selected firms’ proposals represent a range of stablecoin use cases, including payments, wholesale settlement and crypto trading. Each firm will receive feedback from FCA specialists while helping to shape the UK’s regulatory approach. 

Matthew Long, director of payments and digital assets at the FCA said: “We are supporting UK stablecoin issuers to ensure they can be trusted for payments, settlement and trading. It will benefit consumers and financial transactions and help to deliver the FCA’s strategy and the Government’s National Payments Vision.”   

The testing is part of the FCA’s broader work to enable innovation across UK financial services and complements other innovation initiatives such as the Digital Securities Sandbox (DSS).  

Testing begins in early 2026 and the findings will help shape the UK’s final stablecoin rules later in 2026.

FF NEWS TAKE: This regulatory action definitively moves the needle by providing a concrete path for stablecoin issuance to achieve full regulatory legitimacy in a major jurisdiction. The inclusion of Revolut highlights the consumer demand, while the focus on wholesale use cases suggests a strategic push for efficient market infrastructure. The key element to watch for next is the specific findings from this early 2026 testing phase. These real-world data points will dictate the stringency of the final rules slated for late 2026, which will in turn determine the speed and competitive advantage of the first fully regulated UK stablecoin providers
