Monzo's safety net stays British even if its owner does not

What a buyer is actually buying

The valuable thing inside a retail bank is not the app. It is the current accounts: money that sits there, costs the bank almost nothing, and earns whatever Bank Rate happens to be. That is why deposit franchises change hands, and why they are worth more when rates are going up rather than down.

Which is the backdrop here. The Bank of England’s Market Participants Group — a forum where senior market people talk at the Monetary Policy Committee while the Committee listens — met on 24 September. The minutes record agreement that the outlook and the Committee’s own communications were consistent with market expectations that Bank Rate may need to be raised. A pile of cheap sterling deposits is a better asset in that world than it was six months ago.

So when a Brazilian digital bank is reported to be in talks to take over a British one, the commercial logic needs no explaining. What needs explaining is the part that is not commercial at all.

The guarantee does not emigrate

A UK bank licence is not an ordinary asset. It comes bundled with things the state supplies: access to the payments system, and the Financial Services Compensation Scheme, which stands behind eligible deposits up to the protected limit and is funded by levies on other UK financial firms. If a deposit-taker fails, the resolution machinery that decides what happens next sits at the Bank of England, and the bill — one way or another — lands in Britain.

None of that changes when a shareholder register changes. The protection is attached to the licence, not the owner. So a sale transfers the upside of a British deposit franchise to a new owner abroad while leaving the downside exactly where it was.

That is not a scandal. It is the ordinary arrangement for every foreign-owned bank operating in the UK as a subsidiary, and it has worked for decades. It works because the subsidiary is made to stand on its own: it holds its own capital against its own risks, meets its own liquidity requirements, and has a board with legal duties to the subsidiary rather than to the group. Ownership is permitted precisely because independence is engineered.

Three things worth writing down

Any approval of a change of control at a UK deposit-taker turns on whether the acquirer is financially sound and fit to own it. That test is necessary. On its own it is backward-looking: it asks what the buyer is like today, not what happens to the bank on the worst day.

Three conditions answer that second question. First, capital and liquidity held in the UK entity at levels that do not assume a rescue transfer from the parent, because in the stress where the transfer is needed the parent is usually stressed too. Second, a board with genuine independent membership and an explicit ability to refuse a dividend or an intragroup loan the parent wants. Third, operational continuity: if technology, fraud systems or treasury functions are migrated to the group, the contracts must keep those services flowing through the parent’s own distress, not stop when the invoices stop being paid.

None of this is exotic. All of it is standard supervisory practice. The gap is that it is applied privately, and the public — whose compensation scheme is on the hook — never learns which conditions were imposed, or whether any were.

The case against this argument

The strongest objection is that I am describing protectionism with better manners. Britain spent a decade making it easier to start a bank, and it worked: new licences, new competitors, a real dent in the incumbents’ hold on current accounts. Every one of those ventures was funded by investors who needed an eventual exit, and a trade sale to a larger foreign owner is the most common exit there is. Make that exit slower, costlier or politically fraught, and you raise the cost of capital for the next challenger before it has opened a single account. You do not get more competition by making it harder to leave.

There is a second objection: a bigger parent can mean a bigger balance sheet, more lending capacity and cheaper funding, which is good for customers. Foreign ownership of British banks is not a novelty, and the ones that are foreign-owned do not obviously serve customers worse.

Both points are right, and neither is an argument against disclosure. I am not asking for a veto. I am asking that when the state grants permission for someone to own a claim on state-guaranteed deposits, the terms of that permission are visible. Publishing conditions does not deter a serious acquirer — a serious acquirer expects them. It deters an acquirer who was hoping nobody would ask about intragroup funding.

The part regulation cannot fix

Underneath all of this sits a separate British problem, and it is not the regulator’s to solve. The UK has become good at licensing challenger banks and poor at funding them to scale. When the only realistic path from promising to large runs through a foreign buyer, the country keeps getting the startup phase of an industry and exporting the mature one. That is a capital markets failure, not a supervisory one, and no change-in-control test will repair it.
