The Bank of England plans a regulatory framework for sterling stablecoins used at systemic scale, with final rules targeted for the end of 2026 and operation from 2027. The proposal is narrower than “all crypto”: it focuses on stablecoins that become important for everyday UK payments and financial stability.
What is a systemic stablecoin?
A stablecoin is a digital token designed to maintain a stable value, often against a currency such as sterling. In the proposed UK framework, HM Treasury would decide whether a payment system is systemic using statutory criteria, including the consequences its failure could have for the financial system, businesses and the wider economy.
The Bank’s June 2026 policy statement and draft Code of Practice therefore addresses tokens used at scale as money. Stablecoins used mainly for non-systemic cryptoasset trading would not fall under this Bank regime; the FCA would supervise that non-systemic activity.
How would issuers have to back the tokens?
The Bank says a systemic issuer could hold up to 70% of its backing assets in interest-bearing, short-term UK government debt, with the remainder in central-bank deposits. The mix is intended to give issuers a viable model while keeping highly liquid assets available for redemptions.
The important consumer concept is redemption: a token presented as stable money needs credible assets and operational arrangements that support prompt exchange back into sterling. Detailed resilience, governance and safeguarding obligations are part of the draft framework.
Is the £40 billion figure a customer holding limit?
No. The Bank replaced the temporary individual holding limits discussed earlier with a proposed £40 billion issuance guardrail for each systemic stablecoin. That limit would apply to the total amount issued by a systemic scheme, not to what one household or business may hold.
The Bank describes the guardrail as temporary. It would be reviewed regularly and removed once risks to the economy’s supply of credit had been addressed. The rationale is that a rapid shift from bank deposits into new tokens could otherwise affect banks’ funding and lending.
Are these rules already final?
Not entirely. The policy statement records decisions after an earlier consultation, but the Code of Practice remains in draft. Feedback is invited until 22 September 2026, and the Bank intends to finalise the code by the end of the year. Further material is expected alongside the FCA’s final rules.
What changes for users in 2027?
If the timetable holds, regulated UK-issued stablecoins could operate within an end-to-end regime from 2027. That does not mean every stablecoin becomes Bank-regulated, risk-free or equivalent to a bank deposit. Users will still need to check the issuer, the token’s regulatory status, redemption terms, fees and whether normal deposit protection applies.
The clearest change is institutional: a stablecoin that grows into a systemically important payment method would face Bank oversight designed around financial stability, while the FCA covers conduct and the wider non-systemic market, as the two regulators explain in their joint approach.
