Bank of England finalizes sterling stablecoin rules

TLDR

The Bank of England has set a detailed, near-final rulebook for sterling stablecoins that could launch under full regulation from 2027.

1. The framework replaces per-user holding caps with a temporary 40 billion issuance ceiling per systemic GBP stablecoin and tight but clearer reserve and redemption rules.
2. Issuers can hold up to 70% of reserves in short-term UK government bonds, must keep at least 30% at the Bank of England, and redeem at par within 24 hours, but cannot pay interest.
3. The regimes impact will depend on which tokens are designated systemic, how the cap evolves, and whether UK rules attract serious GBP stablecoin issuers versus entrenched dollar stablecoins.

Deep Dive

1. What The New Rules Actually Do

The Bank of England has finalized a policy framework for sterling-denominated systemic stablecoins, aiming for a supervised launch in 2027 after consultation on a detailed Code of Practice through September 2026. A key shift is scrapping previous plans to cap individual holdings (20,000 for retail, 10 million for businesses) and instead imposing a temporary 40 billion issuance ceiling per systemic pound token, designed to limit system-wide risks while allowing scale.[]()

The rules require full backing, with up to 70% of reserves in short-dated UK government securities and at least 30% in non?interest?bearing deposits at the Bank of England, plus redemption at face value within 24 hours. Stablecoins will not be covered by the UKs 120,000 deposit insurance. Oversight is split: the BoE supervises systemic tokens, the FCA handles non-systemic ones, and HM Treasury designates which are systemic.[]()

2. Why This Matters For Crypto Users And Issuers

For users, this regime makes future GBP stablecoins look much closer to regulated e?money than to unregulated crypto tokens, with strict backing, redemption, and liquidity safeguards, but no yield for holders and no deposit insurance. For issuers, the 40 billion cap per token and the 30% non?yielding cash requirement constrain profitability and maximum scale compared with giants like USDT and USDC, which already have much larger supplies.[](https://cryptoslate.com/bank-of-england-stablecoin-path-pound-tokens-face-40b-ceiling/)

The framework responds to industry criticism that the earlier draft was too restrictive, softening reserve constraints and removing personal holding limits while still guarding against rapid outflows from bank deposits into stablecoins. Overall, it signals that the UK wants GBP stablecoins as a regulated payments rail, not as an uncontrolled parallel money system.

3. What To Watch Next

The 40 billion issuance ceiling is explicitly described as temporary and will be reviewed once the BoE is comfortable that large pound tokens do not threaten bank funding or credit provision.[](https://cryptoslate.com/bank-of-england-stablecoin-path-pound-tokens-face-40b-ceiling/) How quickly that cap is relaxed will shape whether a single dominant GBP stablecoin can emerge.

Key milestones are: the consultation on the BoE Code of Practice through 22 September 2026, final rules by end?2026, and which tokens the UK designates as systemic. In parallel, the FCA is building its own rulebook for non?systemic tokens, and global regimes like the EUs MiCA and the US GENIUS Act are advancing, so issuers will arbitrage jurisdictions when deciding where to base GBP products.

Conclusion

The Bank of England has moved from abstract principles to a concrete, conservative but usable playbook for sterling stablecoins, trading some growth potential for financial stability. If credible issuers step in and the 40 billion cap proves flexible, the UK could develop a trusted GBP stablecoin layer in parallel with dominant dollar tokens, giving crypto users a safer, regulated option for pound exposure.
