UK Stablecoin Framework Sets the Rules but Risks Losing the Market

The Bank of England’s (BoE) stablecoin consultation represents a significant step forward for the U.K. in positioning the role of stablecoins in the financial system. 

From a policymaker’s perspective, it demonstrates the Bank’s focus on resilience, transparency, and operational safeguards. 

For the industry, it signals that the U.K. is serious about creating a framework that could support large-scale adoption. 

However, some operational requirements, such as holding limits and reserve composition rules, remain challenging.

Overall, it lays the foundation for a more robust and credible stablecoin ecosystem, but the details will ultimately determine whether issuers see the U.K. as a viable hub.

Why Only Systemic Stablecoins Face Bank of England Oversight

The Bank of England’s proposed regime applies only to systemic stablecoins that could pose risks to financial stability.

Non-systemic issuers fall under the Financial Conduct Authority (FCA) regime, which is more proportionate and broadly aligned with what other major jurisdictions are introducing.

For the systemic category, strong reserve and safeguarding requirements are appropriate because firms at that scale need to demonstrate resilience under stress. 

Under the proposals, systemic stablecoin issuers in the U.K. would have to hold at least 40% of their reserves at the central bank in accounts that pay no interest, making them considerably more resilient, but significantly less profitable than smaller issuers. 

A transition regime between the FCA and the BoE regimes has been proposed, but it remains to be seen whether any commercially viable business model exists for large-scale issuers.

Operational Resilience and Stablecoins: Risks Regulators Still Overlook

In general, regulators are highly attuned to the potential risks. But one area that they seem less focused on is key management. 

Prospective stablecoin issuers come to Fireblocks to address the inherent operational and security challenges associated with blockchains, including securing their smart contracts, ensuring transactions are protected by the right governance policies, and keeping up with innovations across many different blockchains in a rapidly evolving industry. 

We would naturally advocate for a technology-neutral stance that emphasizes the importance of robust security and operational safeguards.

Transparency vs Privacy: What Stablecoin Disclosures Actually Build Trust?

Transparency is most effective when it gives counterparties confidence that stablecoins are fully backed and redeemable at par. 

Public reporting on reserve composition or independent audits allows stakeholders to verify solvency in a meaningful way. 

Conversely, disclosure of transactional data or internal operational processes could raise privacy concerns or become an excessive burden. 

One area where the U.K. regime is at risk of getting this wrong is the proposed holding limits. 

While they are designed to mitigate risks to financial stability, they may create a considerable burden on stablecoin issuers to monitor individuals’ holdings, which would likely raise concerns about surveillance.

Sterling Stablecoins and Monetary Sovereignty in the UK

The Bank of England appears to be focused on ensuring that any sterling-backed systemic stablecoin operates in a manner that does not compromise monetary policy or financial stability. 

By setting clear reserve and operational standards, the consultation aims to safeguard the integrity of the pound while still allowing private issuers to innovate. 

Regulators are walking a fine line, providing room for new payment rails and programmable money, while trying to limit outflows from bank deposits, which support credit in the economy. 

However, they must recognize that some shift in customer behavior is inevitable, and that a more efficient payment system with marginally smaller bank balance sheets might be a healthier and more productive mix for the U.K. economy.

Striking the right balance will be crucial to promote innovation without compromising the monetary policy objectives.

Can UK Regulation Keep Pace With Stablecoin Innovation?

The U.K. is taking a structured, methodical approach, which has real advantages for long-term credibility but can feel slow compared to the speed at which stablecoin models evolve. 

From my time at the Bank, I understand why regulators move cautiously; once you set the rules for money, they’re hard to roll back. 

But from the industry side, there’s a genuine risk that the lack of urgency and overly rigid requirements could limit the U.K.’s ability to attract serious issuers, especially when the U.S. is moving so quickly at the state and federal level to create clearer pathways.

If there’s one area where I would like to see the U.K. push further, it’s in exploring whether issuers should receive some remuneration on the reserves they must hold at the Bank. 

Historically, that’s been off-limits, but with programmable money and wholesale Central Bank Digital Currencies (CBDC) experiments, it’s no longer technically unthinkable. 

A step like that would show the U.K. is willing to innovate within prudential boundaries, and those kinds of signals matter in a market where business models can change in a single cycle of technological progress.

Digital Pound vs Sterling Stablecoins: Competition or Coexistence?

CBDCs and regulated stablecoins, as well as tokenized deposits issued by banks, can complement each other neatly if designed thoughtfully. 

A digital pound would provide households and businesses with a state-issued form of digital money, while tokenized deposits can make banks more efficient, and private stablecoins could support innovation in cross-border payments and programmable finance. 

All three forms of money should coexist, provided clear operational and regulatory boundaries are established. In practice, stablecoins may leverage central bank settlement rails to improve efficiency, while still offering flexibility for new business models that a CBDC alone might not provide.

Fireblocks aims to deliver industry-leading security and governance for all blockchain interactions. So I am naturally supportive of robust policies and controls that protect minting and treasury operations – the kinds of controls that protect against minting trillions of dollars of a stablecoin by accident. 

What UK Stablecoin Rules Mean for Banks and Institutional Adoption

One of the most interesting ideas in the consultation paper is the suggestion that the BoE might make available a liquidity facility for systemic stablecoins. The details are still to be made clear. 

Still, it would presumably allow issuers to place government bonds as collateral in return for short-term central bank money, something that is only made possible by requiring stablecoin issuers to use a deposit account at the central bank. 

The idea goes beyond the thinking of other central banks around the world and could make the U.K. regime considerably more resilient to stressed events.  

On the flip side, the BoE has proposed that as much as 40% of reserves be held in these deposit accounts without being paid any interest. 

That makes the U.K. regime less profitable than anywhere else in the world, and raises questions about the business models that are viable in this regime. 

These fundamental questions, although they only apply to stablecoins, are already holding back the stablecoin industry in the U.K.

Two other areas of contention are the proposed holding limits and the strict requirements on redemption into cash. 

Both are well-intentioned, but suggest a lack of practical understanding of how digital assets can and do work today, and are making prospective issuers think twice about the U.K.

Why the UK’s Stablecoin Decisions Matter for Global Innovation

Regulated stablecoins are not just a technical innovation; they have practical applications in improving payment efficiency, operational resilience, and cross-border liquidity.

The U.K. has definitely fallen behind other jurisdictions. 

But it has an opportunity to set a high standard globally by demonstrating how stablecoins can operate safely within a mature financial system. 

Rules that combine operational rigor, transparency, and flexibility could encourage innovation while protecting stability. 

But they also need to be pragmatic, and in a global market, they simply can’t ignore the policies that have been laid out elsewhere around the world. 

Infrastructure providers play a critical role in translating these rules into practice, ensuring that secure custody, treasury, and settlement systems support scalable adoption. 

Getting this balance right could yet create a role for the U.K. in digital finance globally, whereas missteps at this point will likely push innovation elsewhere.
