Bank of England Banker to the Stablecoin Plan Softens Caps

The phrase that traveled this week is blunt: a Bank of England banker to the stablecoin role is now official messaging. Crypto Briefing reported on October 11 that Deputy Governor Sarah Breeden used that wording as the central bank explained how systemic sterling stablecoins would hold reserves, including unremunerated deposits at Threadneedle Street, under rules due to be finished by the end of 2026.

What happened

The comment sits on a June 22, 2026 policy statement and draft Code of Practice that The Block unpacked when it was published. The Bank of England banker to the stablecoin design replaces earlier individual holding caps with a temporary £40 billion issuance guardrail for each systemic coin. Issuers may hold 70% of backing assets in short-term UK government debt with residual maturity of up to six months, up from 60% in the November 2025 proposal, and must keep the remaining 30% as deposits at the Bank, down from 40%.

Redemptions must be processed as soon as practicable and within 24 hours of a complete request, The Block reported, and systemic issuers may not pay interest on holdings, though activity-based rewards can remain if they fit a payments use case. Capital must equal the higher of six months of operating expenses or the cost of recovery and orderly wind-down planning, with reserves held in trust structures meant to protect holders. Coins that are not designated systemic and are used mainly for crypto trading, including USDT and USDC, stay under the Financial Conduct Authority alone.

Breeden's May City Week speech already framed the Bank's retail vision as a multi-money system in which tokenised bank deposits, regulated stablecoins and, potentially, a digital pound compete while remaining interchangeable. In that speech she said draft systemic-stablecoin rules would arrive the following month and that temporary issuance guardrails were on the table as an alternative to holding limits.

Why it matters

Calling the central bank the Bank of England banker to the stablecoin is a political as well as a technical signal. Deposit access at the Bank is how issuers promise fast redemption in a run; a higher gilt share is how they earn a return on the rest. Crypto Briefing stressed that none of the regime is live yet: the Bank aims to finish the framework by the end of 2026, with operations under it slated from 2027. Coinbase's Katie Harries told The Block the package ranks among the strongest stablecoin regimes globally, while asking what "temporary" means for the issuance cap and whether sterling coins will be allowed to settle core wholesale markets.

The UK path also matters beside other stablecoin files we have covered, from the ESMA unauthorized stablecoins deadline in Europe to the U.S. ADAPT Act stablecoin tax debate. Issuers that want a sterling product now have a clearer sketch of reserve mix, redemption clocks and the Bank of England banker to the stablecoin funding channel, but they still face a year of final drafting.

Industry pushback on the earlier holding-cap idea helps explain why Breeden's banker line resonated. In the May speech she had already signalled openness to temporary issuance guardrails as a cheaper way to limit rapid stablecoin growth than caps on what individuals and businesses could hold. The June statement made that pivot concrete: size limits sit on the coin, not on each wallet, and the Bank of England banker to the stablecoin reserve split funds income (gilts) and run-risk (central-bank deposits). Crypto Briefing emphasised that issuers still have roughly a year and a half from the June publication before 2027 operations, which is a long time in a market where dollar stablecoins already clear huge volumes under other rulebooks.

Comparisons with the U.S. GENIUS Act and EU MiCA regimes are inevitable. The Block's reporting that only the UK is capping issuance of stablecoins in its own currency is the line compliance teams will underline in board decks. Whether wholesale settlement is allowed will decide if sterling coins become plumbing for gilt and equity tokenisation or remain a retail payments experiment. Until the final Code answers Harries's questions, the Bank of England banker to the stablecoin slogan is best treated as a direction of travel with important blanks still unfilled.

What's next

Feedback on the June draft ran to September 22, The Block said. Final Code language, designation criteria for systemic status and any wholesale-settlement permissions will decide whether the issuance guardrail is a bridge or a lasting ceiling. Until then, the Bank of England banker to the stablecoin line is best read as a design choice: the state will hold part of the reserve, and the market will live inside a size cap while that experiment runs.
