TLDR
The Bank of England has dropped proposed per-user limits on sterling stablecoin holdings and replaced them with a big issuance cap per coin.
- The BoE scrapped retail and business holding caps and instead set a temporary 40 billion issuance cap for each systemic sterling stablecoin, while easing reserve rules.
- Users and businesses can now hold unlimited amounts, but issuers face strict 24-hour redemption, high-quality collateral and no-yield rules, shaping how UK stablecoins compete with dollar and euro rivals.
- The framework is final in design but consultative until late 2026, with a 2027 launch targeted, so how the temporary cap evolves will be key for long term market impact.
Deep Dive
1. What Changed In The Rules
Previous drafts would have capped individuals at 20,000 and businesses at 10 million per sterling stablecoin. After strong pushback, these per-holder caps have been dropped and replaced by a temporary aggregate issuance cap of about 40 billion per systemic stablecoin, according to multiple reports including CoinDesk.
Issuers can now hold up to 70% of reserves in short term UK government debt and 30% as non interest bearing deposits at the BoE, a shift from a more restrictive 60:40 split. Stablecoins must remain redeemable at par within 24 hours, even in stress.
Oversight shifts from micro managing each wallet to controlling system-wide scale and reserves, which is simpler operationally but still caps how large any one sterling stablecoin can grow.
2. Impact On Users, Issuers And Competitiveness
For users, the big change is freedom to hold any size balance without regulatory caps, as long as the stablecoin itself has not hit the system-wide issuance ceiling. Transaction frequency and size limits have also been removed for both households and corporates.
For issuers, the 70% gilts and 30% zero yield deposits mix plus a 24-hour redemption requirement aims to keep coins safe but still commercially viable. However, issuers generally cannot pay simple deposit like interest on balances, only limited activity based rewards as described in the same framework.
UK stablecoins could be attractive as payment rails and settlement tokens, but they may struggle to match the yield and scale of offshore dollar stablecoins unless rules keep evolving.
3. Timeline And What To Watch Next
The policy statement and draft rules are positioned as final in structure, but the BoE is taking feedback until September 2026, with a goal of finalizing the rulebook by year end and enabling launches from 2027, as highlighted by Cointelegraph.
Key open issues include how long the temporary 40 billion cap lasts, whether stablecoins can be used for wholesale settlement in core markets, and how the regime compares in practice with MiCA in the EU and evolving US rules.
For crypto builders, the UK now looks more open than before, but the real edge will depend on whether caps ease and use cases expand as the market grows.
Conclusion
The Bank of Englands move to scrap retail stablecoin caps while imposing a large issuance ceiling and strict reserve rules signals a clear intent. It wants sterling stablecoins to exist and scale as regulated payment infrastructure, but only within tightly managed system-wide risk limits. How the temporary cap and no-yield stance evolve will determine whether UK stablecoins become globally competitive or remain a niche, domestically focused tool.
