BOE’s Breeden says unhosted wallets won’t be permissible in

Bank of England Deputy Governor Sarah Breeden told a House of Lords committee that unhosted wallets “will not be permissible in the UK,” putting self-custody directly into the UK stablecoin policy debate. Stablecoin and banking-sector figures argue the stance could push GBP stablecoins into closed-loop designs and be difficult to enforce in practice.

Key Takeaways

A Bank of England deputy governor told the House of Lords that unhosted wallets “will not be permissible in the UK,” contrasting the approach with the US.
The central bank’s stated concern is financial stability, with stablecoin yields framed as a potential driver of deposit outflows and reduced bank credit availability.
tGBP’s CEO warned that restricting transfers to registered VASPs or custodians could force whitelisting models and even token re-issuance if self-hosted holdings become non-compliant.
The BOE’s latest stablecoin consultation paper published in November did not explicitly propose an unhosted-wallet ban, and any rule change would run through a Treasury-led FCA process under the 2023 Financial Services and Markets Act.

Breeden’s Lords Testimony Puts Self-Custody in the Crosshairs

Sarah Breeden, deputy governor at the Bank of England, told the House of Lords Financial Services Regulation Committee that “Unhosted wallets will not be permissible in the UK. They are permissible in the US regime,” describing unhosted wallets as arrangements where there is no regulated wallet provider ensuring AML and KYC compliance.

Breeden also signaled some flexibility on the policy objective, saying the BOE is “open to other ways of achieving the objective” tied to maintaining credit availability. Even so, the categorical phrasing on unhosted wallets injects near-term policy risk into UK-facing stablecoin rails, because it frames self-custody as a design feature regulators may try to constrain rather than accommodate.

BOE’s Financial-Stability Case: Deposits, Yields, and Credit Availability

The BOE’s rationale, as described in the committee discussion, is not primarily a crime-finance argument. It is a bank-funding and credit-conditions argument.

Breeden framed the BOE’s role as preventing a sharp contraction in lending, saying: “But I think you would expect us as the financial stability authority to ensure that there isn't a precipitous drop in credit to the businesses and households in the UK,” with stablecoins positioned as a potential channel for deposit outflows if they offer higher yields than traditional bank products.

For traders, that matters because it places stablecoin policy inside a broader financial-stability perimeter. The debate is effectively about whether stablecoin adoption changes the marginal cost of bank funding and, by extension, the availability of credit in the UK.

Issuer and Bank Pushback: Whitelists, Token Re-Issuance, and Competitiveness

Industry objections focus on how a restriction would be implemented. Benoit Marzouk, CEO of tGBP, said an unhosted-wallet restriction would “wipe out hard-earned network effects,” arguing that if transfers are limited to registered VASPs or custodial wallets, “existing GBP stablecoins [...] would become in breach of regulations with holding on self-hosted or issuers would be forced into whitelisting models and re-issuing new tokens.”

That is the mechanical risk: a VASP-only transfer regime pushes GBP stablecoins toward whitelists, closed settlement graphs, and potential token migration events. Marzouk argued that a stablecoin limited to predefined wallets stops functioning like an open blockchain asset, saying: “A plane without wings is no longer a plane. Likewise, a stablecoin or blockchain asset that can only be transferred to a predefined list of wallets is not truly blockchain, it is effectively e-money within a closed ecosystem and then you don't need a separate regulation.”

Joey Garcia, chief strategy, policy, and regulatory affairs officer at Xapo Bank, warned the stance would be interpreted as “a signal of a hostile regulatory environment, discouraging developers and investment in the UK’s fintech sector.” He also challenged enforceability, saying: “As long as the internet and public blockchains exist, a direct ban on wallet creation and use is not practically enforceable.”

Consultation Paper vs. Committee Remarks: Where the Rule Could Actually Land Next

There is a gap between the headline testimony and the formal rulemaking record so far. The BOE’s latest consultation paper on stablecoins, published in November, did not explicitly propose an unhosted-wallet ban.

Any shift from committee remarks to binding restrictions would run through a Treasury-led process under the Financial Conduct Authority framework set by the 2023 Financial Services and Markets Act. Near-term signals that matter are Treasury or FCA communications clarifying whether stablecoin rules will restrict transfers to self-hosted wallets, and follow-up testimony from BOE officials that specifies scope and enforcement mechanics.

On the industry side, traders should watch for issuer-level implementation talk: whether GBP stablecoin operators move toward whitelisting, token re-issuance, or routing liquidity and product launches away from the UK if the policy stance hardens.

The Trade Is in the UK Policy Path, Not the Soundbite

Breeden’s quote is a real catalyst because it tells the market what the BOE wants, even if the consultation paper has not yet codified it. The threshold that matters is whether Treasury and the FCA translate “not permissible” into an enforceable rule that effectively confines stablecoin transfers to registered VASPs and custodians.

If that constraint shows up in the formal framework, the setup starts to look structural rather than narrative-driven. It would reshape how GBP stablecoins circulate, with whitelists and potential token re-issuance becoming operational requirements instead of edge-case contingencies, and that is what would make this development matter in practical terms.
