The United Kingdom (UK) and the United States (USA) are considering a shared sandbox to align licenses and regulations on digital assets: a key step in global crypto regulation.
Crypto Regulation UK-USA: Towards a Joint Sandbox?
The United Kingdom and the United States are in preliminary talks to create a shared testing environment (“sandbox”) for digital assets and licenses. The goal is to harmonize standards and procedures across both markets.
This was revealed by Lisa Cameron, founder of the UK‑US Crypto Alliance and former British MP, during a meeting at the United Nations Offices in Copenhagen. According to Cameron, the sandbox would facilitate cross-border operations with common rules.
What is the regulatory passport and why it matters
The so-called regulatory passport would allow companies authorized in one of the two countries to serve clients in the other without new authorizations. This would reduce time, costs, and bureaucratic duplications.
What concrete steps are already underway?
The idea is rooted in growing cooperation. At the beginning of the year, the Treasury departments of the two countries established a transatlantic task force to assess joint regulatory projects in the short term, as indicated by the HM Treasury of the United Kingdom. Additionally, on September 22, 2025, Bitcoin Magazine republished an article from the Financial Times about the creation of the working group.

Simultaneously, the Bank of England has proposed new regulations for stablecoins pegged to the pound, with increased oversight on payments, in line with U.S. guidelines.
Cameron reported positive discussions with U.S. senators and members of the SEC’s crypto task force, indicating a potential strengthening of regulatory cooperation.
Is the United Kingdom at risk of falling behind?
However, Cameron warns that delays could cause London to lose ground. Several startups are moving towards jurisdictions with clearer regulations and more decisive public support.
That said, the United States is showing a clearer direction on emerging technologies, while the United Kingdom is still in the debate phase. “The window of opportunity will not remain open forever,” he stated.
What Would It Mean for Businesses?
A joint sandbox and regulatory passport would reduce duplications and uncertainties, allowing operations in two markets with a single set of standards. Overall, this could accelerate investments and innovation, fostering transatlantic crypto cooperation.
For both countries, a shared sandbox would represent a step towards global standards and a more coordinated UK-USA crypto regulation, transforming competition into cooperation on a rapidly evolving frontier.
