Bank of England Introduces New Stablecoin Rules, Plans Full Rollout by 2027
The Bank of England (BoE) has taken an important step toward regulating stablecoins in the United Kingdom. The central bank recently released a policy statement and a draft set of rules for pound-backed stablecoins that could become widely used in the country’s payment system.
These new rules are specifically aimed at “systemic” stablecoins. These are digital currencies that are used on a large scale and could have a significant impact on the UK financial system. The Bank of England believes that if stablecoins become a common payment method, they must be regulated carefully to protect financial stability and consumers.
What Are Systemic Stablecoins?
Stablecoins are cryptocurrencies designed to maintain a stable value by being linked to traditional assets such as government-issued currencies. In this case, the focus is on stablecoins backed by the British pound.
According to the Bank of England, a stablecoin becomes “systemic” when it is widely used for payments and reaches a size where it could affect the broader financial system. If such a stablecoin faces problems, it could create risks for businesses, consumers, and the economy.
The responsibility for deciding whether a stablecoin is systemic will belong to HM Treasury. This approach follows the UK’s broader regulatory framework, where authorities identify activities that could have a major impact on financial stability.
New Rules for Stablecoin Reserves
One of the most important parts of the new framework is the rule regarding reserve assets.
Stablecoin issuers are required to hold reserves that support the value of their digital tokens. Under the proposed rules, issuers of systemic pound-backed stablecoins will be allowed to invest up to 70% of their reserves in interest-bearing UK government debt.
This is an increase from the earlier proposal, which had suggested a limit of 60%.
The Bank of England believes this change will help stablecoin issuers manage their reserves more effectively while maintaining safety and stability. Government debt is generally considered a low-risk investment, making it a suitable asset for backing stablecoins.
Temporary £40 Billion Issuance Cap
Another major change involves the limits placed on stablecoins.
Previously, regulators considered imposing restrictions on how much stablecoin an individual or business could hold. However, after receiving feedback from industry participants, the Bank of England decided to take a different approach.
Instead of limiting users, the central bank is proposing a temporary issuance cap of £40 billion. This means that the total amount of a systemic stablecoin that can be issued will be limited until regulators are satisfied that potential risks have been properly addressed.
The Bank of England has stated that this cap is a temporary safeguard and will be reviewed regularly. It could eventually be removed if authorities believe the risks to financial stability have been reduced.
Why Regulators Are Concerned
A major concern for policymakers is the possibility that stablecoins could reduce the amount of money held in traditional banks.
If millions of people start using stablecoins instead of bank deposits, banks could lose an important source of funding. Since banks use deposits to provide loans to households and businesses, a significant reduction in deposits could affect the availability of credit in the economy.
Regulators worry that large-scale shifts from bank accounts to stablecoins could weaken the banking system’s ability to support economic growth.
For this reason, the Bank of England wants to create safeguards that allow innovation while protecting the financial system.
Moving Away from User Holding Limits
The new framework marks a significant shift from earlier proposals.
In a consultation published in November 2025, the Bank of England suggested strict limits on stablecoin holdings. Individuals would have been restricted to holding up to £20,000 of a specific stablecoin, while businesses would have faced a limit of £10 million.
The goal of these restrictions was to prevent large amounts of money from leaving traditional banks too quickly.
However, many industry participants argued that these limits would make stablecoins less useful for everyday transactions. They also warned that such restrictions could make UK stablecoins less competitive compared to dollar-backed stablecoins available in other markets.
Companies further noted that monitoring and enforcing individual holding limits would create significant operational challenges.
After reviewing this feedback, the Bank of England decided to replace the proposed holding limits with the broader £40 billion issuance cap.
Balancing Innovation and Financial Stability
The updated approach shows that the Bank of England is trying to balance two important goals.
On one hand, regulators want to encourage innovation in digital payments and financial technology. Stablecoins have the potential to make transactions faster, cheaper, and more efficient.
On the other hand, authorities want to ensure that the growth of stablecoins does not create risks for banks, consumers, or the wider economy.
By focusing on reserve requirements and overall issuance limits instead of individual user restrictions, the Bank of England hopes to create a system that supports innovation while maintaining financial stability.
Timeline for Implementation
The Bank of England has outlined a clear timeline for introducing the new framework.
The central bank plans to finalize its rulebook by the end of 2026. Once the rules are completed, the new regulatory regime is expected to become operational in 2027.
Only stablecoins classified as systemic will fall under the Bank of England’s direct supervision. Non-systemic stablecoins will continue to be regulated by the Financial Conduct Authority (FCA) for relevant activities.
The Bank of England’s proposed stablecoin framework represents a major development in the UK’s approach to digital asset regulation. By allowing up to 70% of reserves in government debt, introducing a temporary £40 billion issuance cap, and moving away from strict user holding limits, the central bank is attempting to create a practical and balanced regulatory system.
As stablecoins continue to gain popularity worldwide, the UK’s new framework could become an important model for how governments regulate digital payment systems while protecting financial stability. With the final rules expected by 2026 and implementation planned for 2027, the country is positioning itself for the next phase of digital finance.
