The Digital Pound: UK's CBDC Journey and Why No Decision Has Been Made

In February 2023, the Bank of England and HM Treasury published a joint consultation paper — commonly called the “digital pound consultation” — inviting public views on whether the United Kingdom should introduce a retail central bank digital currency. The language was careful throughout. The consultation did not announce a decision to proceed. It did not present a CBDC as inevitable. It posed a question: would a digital pound be in the public interest, and if so, what should it look like?

Two years on, no decision has been announced. The digital pound project continues — the Bank of England has established a dedicated team, published technology working papers, conducted proof-of-concept work, and consulted with industry — but Bank of England Governor Andrew Bailey and successive Economic Secretaries to the Treasury have consistently declined to commit to building a UK retail CBDC. This sustained equivocation is itself significant, and understanding it requires examining both the genuine technical and policy uncertainty and the political economy of programmable sovereign money.

The Technology Demonstration Work

The Bank of England has not been idle during the consultation period. Its digital pound project team published a technology working paper in 2023 examining the technical architecture options for a retail CBDC, considering whether a digital pound should be account-based or token-based, how it should interact with commercial bank money, and what infrastructure the Bank and private sector payment interface providers would need to build.

The Bank has also engaged with the broader central bank community — including through the BIS Innovation Hub and the G7 working group on CBDCs — to share technology learnings and policy analysis. Governor Bailey has chaired the Financial Stability Board since July 2025, giving him an international platform from which to engage with CBDC policy questions across the G20 — though his FSB role requires attention to financial stability implications of all jurisdictions’ CBDC decisions, not just the UK’s.

Key Design Questions

The February 2023 consultation identified several design questions whose resolution would be required before any build decision. On privacy: a digital pound would necessarily involve the Bank of England (and potentially HM Treasury) having access to transaction data that is currently the preserve of commercial banks. The consultation proposed that the Bank would not have access to transaction data and that digital pound transactions would be private — but the technical and legal architecture to deliver this privacy guarantee has not been finalised.

On programmability: one of the most politically sensitive questions is whether a digital pound would be programmable — capable of having spending restrictions attached by the issuer. A programmable CBDC could, in principle, be designed to expire if unspent, to be restricted to certain categories of goods, or to be conditional on behavioural requirements. The consultation explicitly noted that HM Treasury would not implement programmability features of this kind, but the possibility that a future government could has driven significant parliamentary opposition.

On holding limits: the consultation proposed that individuals would initially be limited to holding between £10,000 and £20,000 in digital pounds, to limit the risk of bank runs during financial stress — depositors moving commercial bank deposits into CBDCs on a large scale could destabilise the banking system by stripping banks of their funding base. The appropriate holding limit, and whether limits are needed at all, remains unresolved.

On retail versus wholesale: the UK consultation focused primarily on a retail CBDC accessible to households and businesses. Wholesale CBDC — accessible only to financial institutions — is a separate but related question, with different implications for the monetary and financial system. The Bank of England has been more open to wholesale CBDC innovation, including through engagement with the BIS Project Meridian.

Parliamentary Opposition

The digital pound attracted significant parliamentary opposition during the 2023-24 parliamentary session. MPs across party lines raised concerns about financial surveillance, programmability, and the implications of state-controlled digital money. The House of Lords Economic Affairs Committee published a critical report in 2023 concluding that the case for a retail CBDC had not been made and that the risks — to privacy, financial stability, and the commercial banking system — required much more careful analysis before any build decision.

This political environment has shaped the government’s cautious posture. Unlike the ECB’s digital euro project, which has proceeded to a preparation phase with a provisional launch target, the UK government has not committed to a similar timeline. The Conservative government that commissioned the 2023 consultation was replaced by a Labour government in July 2024, and the new government has maintained the same consultative posture without acceleration — suggesting the hesitation reflects genuine policy uncertainty rather than purely political opposition.

Comparison with the ECB’s Digital Euro

The European Central Bank’s digital euro project has moved further and faster than the UK’s. The ECB’s Governing Council approved moving to a preparation phase in October 2023, with design work and vendor selection underway. The ECB has been more explicitly committed to the project’s political rationale — defending European monetary sovereignty in a digital age, providing a public payment option as cash use declines — and has framed the digital euro as a strategic necessity rather than an option to be evaluated.

The UK’s more equivocal approach may reflect the Bank of England’s sharper focus on financial stability risks — commercial bank disintermediation, bank run dynamics, and the impact on the monetary transmission mechanism have featured more prominently in UK CBDC analysis than in the ECB’s public communications. Bailey has been notably candid about these risks in public speeches, suggesting the Bank considers them genuine rather than theoretical concerns to be designed around.

Implications for a Tokenizing Financial System

Whether the UK ultimately builds a digital pound matters enormously for the tokenization industry. A retail CBDC would provide settlement money for tokenized asset transactions that does not depend on commercial bank money or existing payment rails — addressing one of the key infrastructure gaps in the tokenized financial system. Without a CBDC, tokenized asset settlement requires either stablecoins (private money) or settlement via existing central bank money systems (slow, limited to banking hours). Wholesale CBDC would address the institutional settlement gap more directly.

The Bank of England’s Project Meridian — an experiment in DLT-based synchronised settlement using central bank money — demonstrates the Bank’s recognition that tokenized markets require new settlement infrastructure. But Meridian is a proof-of-concept, not a live system. The digital pound project’s continued indecision means UK tokenization platforms must build on privately issued settlement assets or existing payment infrastructure for the foreseeable future — a significant constraint on the full realisation of the efficiency gains that tokenized settlement infrastructure promises.
