Key Takeaways:
- UK Stablecoin regulation The Bank of England dropped its proposed individual holding limits of £20,000 for sterling stablecoins after months of industry pressure.
- The BoE is now moving toward aggregate issuance caps placed on token providers instead of tracking individual wallets.
- Revised draft rules arrive in June 2026, with final Codes of Practice expected by late 2026.
The Bank of England just made one of its biggest moves in crypto policy. On May 19 at CityWeek 2026 in London, Deputy Governor Sarah Breeden confirmed the central bank is abandoning its proposed individual holding limits for sterling stablecoins, shifting instead toward aggregate issuance caps placed on token providers. This signals a real change in how UK stablecoin regulation will work going forward. For anyone following the pound-pegged token space, the shift carries serious weight.
How Did the Original UK Stablecoin Rules Work?
The Bank of England opened its consultation on November 10, 2025, covering systemic sterling stablecoins used in retail payments and wholesale settlement. The framework addressed reserves, capital requirements, liquidity, and consumer protection. Two parts of it drew the most fire.
The Holding Limit Proposal
Under the original plan, individuals could hold up to £20,000 per stablecoin, while businesses faced a limit of £10 million per stablecoin. The central bank designed the caps to reduce pressure on commercial bank deposits and slow sudden migration from bank accounts into tokenized money.
Industry groups pushed back hard. They warned that a hard cap on stablecoin holdings would send a “terrible signal” and make real-world use cases almost impossible.
The Reserve Requirement Issue
The BoE also proposed that at least 40% of stablecoin-backing assets sit as non-interest-bearing deposits with the central bank, while the remaining 60% go into short-term UK government debt.
At short-dated gilt yields of about 4%, this split could cost a UK issuer roughly £11.2 million a year for each £1 billion in circulation. That made the economics of UK stablecoin issuance look grim compared to rivals in the US and EU.
Why the Bank of England Decided to Change Course
The reversal came after sustained pressure from multiple directions. Here are the main factors that forced the rethink:
- Enforcing wallet-level limits on decentralized ledgers was always operationally unworkable for stablecoin issuers who do not maintain direct relationships with millions of end users.
- Coinbase’s head of policy for Europe, Katie Haries, said “a cap on stablecoin holdings is a cap on innovation, with real and significant risks for UK competitiveness.”
- Industry experts warned GBP stablecoins could simply be issued from Dublin to avoid UK rules, raising the question of whether the BoE wants to regulate the most-used GBP stablecoin or watch it emerge from another market.
- Breeden acknowledged the BoE’s initial plans may have been “overly conservative” and said the reserve proposal was based on liquidity stress seen during bank runs, including Silicon Valley Bank’s deposit withdrawals in 2023.
By early 2026, appearing before a House of Lords committee, Breeden said the central bank was “genuinely open” to revisiting aspects of the framework, particularly the proposed 40:60 reserve split.
What the New UK Stablecoin Regulation Framework Looks Like
The revised approach shifts focus from consumer-level limits to issuer-level controls. The BoE is not abandoning oversight, it is restructuring where that oversight applies. For a deeper look at how crypto regulatory frameworks generally work, the UseTheBitcoin crypto guides cover the basics well.
Aggregate Issuance Caps Replace Holding Limits
Rather than monitoring individual consumer accounts, the Bank of England is evaluating “temporary guardrails” on the aggregate volume of stablecoins in circulation. Breeden said this approach achieves the central bank’s stability goals at a lower operational cost to the sector, while accommodating high-value corporate payment strategies.
Banks Get a Clearer Path to Stablecoin Issuance
The BoE indicated that traditional banks can issue stablecoins through separate non-deposit-taking entities using distinct branding that can still reference the parent bank. This creates a legal wall between standard deposit banking and digital asset issuance, while letting established institutions participate.
Reserve Rules Are Getting Softer
Cutting the non-interest-bearing floor from 40% to 20% would roughly halve the profitability drag for issuers, bringing UK stablecoin economics within striking distance of MiCA and US issuers. The BoE has not finalized this change, but it is openly on the table.
What Comes Next for UK Stablecoin Policy
The BoE will publish revised draft rules in June 2026, with final Codes of Practice for systemic stablecoins expected by late 2026. The timeline is being aligned deliberately with US legislative developments.
The FCA is running a parallel track. It has made stablecoin payments one of its priorities for 2026 and opened a sandbox for firms testing UK-issued stablecoins, with Revolut, Monee Financial Technologies, ReStabilise, and VVTX already selected for the trial.
The full cryptoasset regime takes effect on October 25, 2027, with a pre-application support service opening in July 2026.
One unresolved gap remains. While the FCA governs smaller stablecoins and the BoE handles systemic ones, no clear mechanism exists for how an issuer moves from FCA oversight into BoE supervision without hitting a wall of sudden regulatory discontinuity. That transition question is still open. You can follow ongoing crypto regulatory updates as this framework develops.
Frequently Asked Questions
What is UK stablecoin regulation?
UK stablecoin regulation is the legal framework governing how digital tokens pegged to sterling or other currencies operate in the United Kingdom. The Bank of England oversees systemic sterling stablecoins, while the Financial Conduct Authority handles smaller, non-systemic issuers.
Why did the Bank of England soften its stablecoin stance?
The BoE softened its stance after industry groups warned that strict holding caps and conservative reserve rules would send a “terrible signal” and make real-world use cases almost impossible. The central bank acknowledged the criticism was valid.
What were the original holding limits the BoE proposed?
The November 2025 consultation proposed individual holding limits of £20,000 per person and £10 million per business for sterling stablecoins. Both figures are now off the table.
What are aggregate issuance caps and how do they differ from holding limits?
Aggregate issuance caps limit the total amount a stablecoin issuer can put into circulation. Holding limits track what each user can own across their wallets. The issuance cap approach regulates the issuer directly rather than monitoring individual accounts, which is far easier to enforce on decentralized networks.
When will the UK publish its final stablecoin rules?
The BoE plans to release revised draft rules in June 2026. Final Codes of Practice for systemic stablecoins are expected in the second half of 2026.
Can UK banks issue stablecoins under the new rules?
Yes. Under the emerging guidelines, banks can issue stablecoins provided the digital assets come from non-deposit-taking corporate subsidiaries. These entities must use distinct branding but can still reference the parent financial institution.
