What the Digital Pound Means for Banks

The Disintermediation Threat

For commercial banks, the digital pound is a double-edged sword. On one hand, it offers new payment infrastructure and potential business opportunities (as Payment Interface Providers). On the other, it threatens to siphon deposits away from banks — a process called disintermediation.

Here's the concern: today, when you deposit £1,000 at Barclays, that money becomes a liability of Barclays. Barclays uses those deposits to fund lending (mortgages, business loans). If you can instead hold £1,000 directly at the Bank of England — risk-free, as a digital pound — why would you keep it at Barclays? If enough depositors move their money, banks lose a cheap funding source and must rely on more expensive wholesale funding, making loans more expensive.

Why This Matters

Bank deposits are the foundation of the UK's credit system. Total household bank deposits in the UK exceed £1.7 trillion. Even a modest shift — say 5% of deposits moving to digital pounds — would represent £85 billion of funding that banks would need to replace. The impact would be:

• Higher lending rates — banks would pass on the cost of more expensive funding
• Reduced lending — particularly to riskier borrowers (SMEs, first-time buyers)
• Lower profitability — the net interest margin compression would hit bank earnings
• Greater systemic sensitivity — during crises, the flight to safety could accelerate

The Bank Run Scenario

The most acute concern is during a banking crisis. In March 2023, Silicon Valley Bank collapsed in the US in part because depositors could move their money out instantly via digital banking. A CBDC could make bank runs even faster — depositors could move unlimited funds from a troubled bank to the risk-free central bank in seconds.

This is why the BOE has proposed a holding limit of £10,000–£20,000. At £10,000, the total potential outflow from bank deposits would be capped at around £500 billion (if all ~50 million UK adults maxed out their wallets). In practice, the BOE estimates actual usage would be much lower. But during a crisis, even the capped outflow could be destabilising if it happened simultaneously.

How the BOE Aims to Mitigate the Risk

• Holding limits — the £10k–£20k cap limits how much can move to the central bank
• No interest on digital pounds — since the digital pound wouldn't pay interest, there's no incentive to use it as a savings vehicle. Your bank account pays interest; your digital pound wallet doesn't.
• Staged introduction — a gradual rollout would let the BOE monitor deposit flows and adjust if needed
• Adjustable limits — the BOE has said limits could be changed over time, including being reduced during stress periods (though this would be politically sensitive)
• Tiered remuneration — in a future evolution, the BOE could apply negative interest rates to digital pound holdings above a threshold during crises, discouraging large balances

Opportunities for Banks

It's not all downside. Banks and fintechs can participate in the digital pound ecosystem as Payment Interface Providers (PIPs), generating revenue from:

• Transaction fees — merchant fees for processing digital pound payments
• Value-added services — budgeting tools, payment scheduling, analytics
• FX and cross-border — converting digital pounds to other currencies
• Lending against digital pound collateral — new lending products
• Custody and wallet services — for businesses holding large digital pound balances

What About Building Societies and Challenger Banks?

Smaller institutions face a particular challenge. The big four banks (HSBC, Barclays, Lloyds, NatWest) have diversified income streams and strong wholesale funding access. Building societies and challenger banks — which rely heavily on retail deposits — could be disproportionately affected by deposit outflows. The BOE has acknowledged this and is considering whether smaller institutions need additional safeguards.

The Narrow Banking Argument

Some economists argue that disintermediation isn't a bug — it's a feature. The "narrow banking" proposal suggests that retail deposits should be backed by central bank reserves, eliminating the risk of bank runs entirely. In this view, the digital pound is a step toward a safer financial system where commercial banks fund lending through equity and long-term debt rather than fragile demand deposits.

The BOE doesn't endorse full narrow banking, but the digital pound moves the system slightly in that direction — giving the public access to risk-free central bank money alongside commercial bank deposits.

What Banks Are Doing Now

• UK Finance — the banking industry body has engaged constructively with the BOE's design phase, seeking to shape the PIP model
• Major banks — are participating in BOE engagement forums and exploring how to offer digital pound wallets alongside existing accounts
• Fintechs — companies like Revolut, Monzo and Wise are well-positioned to become PIPs and are watching the project closely
• Trade associations — are lobbying for a level playing field between banks and non-bank PIPs

The Bottom Line

The digital pound poses a real but manageable threat to commercial banks. The holding limit and non-interest-bearing design are specifically intended to prevent mass deposit migration. Banks that become PIPs can turn the digital pound into a business opportunity rather than a threat. But the structural risk — that central bank money is inherently more attractive than commercial bank money during crises — cannot be fully eliminated by design alone.
