The Bank of England’s proposal to ban unhosted wallets for stablecoin holdings has triggered fierce opposition from UK crypto operators and policy advocates, who argue the measure is unenforceable, economically damaging, and fundamentally incompatible with blockchain technology. Deputy Governor Sarah Breeden revealed the BOE’s stance during House of Lords testimony in March 2026, stating that unhosted wallets “will not be permissible in the UK” — a position that directly contradicts the regulatory approach taken by US authorities. The proposed restriction aims to insulate the UK banking system from deposit flight to higher-yielding stablecoins, but industry figures warn it will cripple GBP stablecoin adoption and push users toward USD alternatives.
BOE’s Stability Rationale Meets Practical Resistance
The Bank of England’s concern centers on financial stability: unhosted wallets remove the intermediary oversight that regulated Virtual Asset Service Providers (VASPs) provide for anti-money laundering and know-your-customer compliance. Without this layer, the BOE fears stablecoins could trigger deposit runs by offering retail savers yields exceeding traditional bank products. However, industry players argue the ban conflates two separate problems. Joey Garcia, Chief Strategy, Policy and Regulatory Affairs Officer at Xapo Bank, stated the restriction “essentially restricts any attempt to understand and mitigate the perceived risks,” suggesting the BOE has rejected empirical analysis in favor of blanket prohibition. Benoit Marzouk, CEO of tGBP stablecoin issuer, framed the logic as absurd: “A plane without wings is no longer a plane.”
Enforcement Feasibility Questioned Across Sector
A critical flaw in the proposal: blockchain’s immutable, peer-to-peer architecture makes wallet restrictions nearly impossible to enforce. Garcia emphasized this directly: “this is extremely challenging to monitor, let alone enforce.” The Travel Rule — an existing regulatory mechanism designed to track crypto transactions between VASPs — was not built to restrict wallet types or validate holder identity post-transaction. Freddie New, Chief Policy Officer at Bitcoin Policy UK, characterized the proposal as structurally flawed, stating it represents “such monumental, such overweening, stupidity, that it is hard to formulate a sensible response.” The BOE has not publicly addressed how enforcement would operate in practice, creating regulatory uncertainty for compliant firms.
Competitiveness and Financial Inclusion at Stake
The ban threatens to hollow out the UK’s nascent stablecoin sector relative to US-based competitors. Marzouk warned the move would “wipe out hard-earned network effects” and constitute “a serious misstep for the UK, risking long-term damage that is hard to unwind.” GBP stablecoins depend on retail adoption for utility; restricting unhosted wallets eliminates remittance corridors, peer-to-peer transfers, and access for unbanked populations — the foundational use cases that justify stablecoin infrastructure. Garcia added that such a ban “would be interpreted as a signal of a hostile regulatory environment,” potentially deterring institutional issuers from launching UK-regulated products. Breeden indicated the BOE remains “open to other ways of achieving the objective” of credit availability, but no alternative framework has been tabled.
Regulatory Timeline and Next Steps Unclear
The BOE published a consultation paper on stablecoins in November (year unspecified), but the wallet ban proposal did not appear in that document. Breeden’s March 2026 testimony suggests the measure may be introduced in forthcoming guidance, yet no formal decision timeline or final regulatory text has been announced. The Financial Conduct Authority and UK Treasury have not publicly commented on feasibility concerns or enforcement mechanisms. Industry groups expect regulatory finalization within months, but the proposal’s viability remains contested between a central bank prioritizing systemic stability and operators arguing the restriction is both counterproductive and technically unworkable.
