The letter arrives on a Tuesday. Two paragraphs. Your bank has reviewed its relationship with you and has decided, with regret, to close your accounts. No reason is given. You have sixty days, sometimes fewer, to move your salary, your direct debits, your savings, and in some cases your business's entire payment infrastructure somewhere else.
You call the branch. The person on the phone is polite and knows nothing. You write to complaints. The reply confirms the decision and cites the terms and conditions. You have been a customer for nineteen years. You have never been overdrawn. It does not matter.
I see a version of this story every single week. Not every month. Every week. And because I advise internationally mobile clients for a living, I see it more often than most. So let me explain what is actually happening, why it is happening to people who have done nothing wrong, and what you should have in place before that letter arrives.
Why Banks Fire Good Customers
The first thing to understand is that your bank did not make a moral judgment about you. It made a spreadsheet decision.
Every customer relationship carries a compliance cost. Anti-money-laundering checks, transaction monitoring, periodic reviews, source-of-funds files, sanctions screening: all of this costs money, and the cost is not evenly distributed. A domestic salaried employee with one incoming payment a month costs almost nothing to monitor. A customer with a foreign address, income in three currencies, a holding company, or a history of crypto transactions costs a great deal more.
Meanwhile, the revenue side of the ledger has collapsed for ordinary retail relationships. Margins on current accounts are thin. So the bank's risk committee looks at whole categories of customers and asks a simple question: does the expected revenue from this segment justify the compliance cost and the regulatory exposure?
For entire categories, the answer is no. The industry calls this de-risking, and the word is well chosen, because the point is not to manage your risk. The point is to remove it from the balance sheet entirely by removing you.
Certain flags make you expensive almost automatically. Political exposure, even at several removes: if your cousin holds public office in another country, you can be classified as a politically exposed person's associate. A foreign residential address, which triggers cross-border reporting and tax documentation. Any visible connection to cryptocurrency, even a single transfer from a regulated exchange years ago. Certain nationalities and countries of birth, which get swept into blanket risk scoring regardless of your individual circumstances. That last one deserves a name: nationality de-risking. Banks will rarely admit to it, but anyone who advises international clients sees the pattern within months.
None of these flags mean you have done anything wrong. They mean you are expensive. And expensive customers get fired.
The Cases I See Weekly
Let me describe the recurring patterns. These are composites drawn from years of client work, not individual case files, but the patterns are real and they repeat with remarkable consistency.
The expat with the home-country account. A German engineer moves to Singapore for work. He keeps his German current account, as almost everyone does, and dutifully updates his address. Eighteen months later the bank writes to say the relationship no longer fits its business model. Nothing changed except his address. A foreign address means overseas reporting obligations, and he has become a cost centre.
The entrepreneur with the complex structure. A British consultant runs her business through a perfectly ordinary arrangement: an operating company, a holding company above it, dividends flowing between them. Her bank's periodic review flags the structure as complex. She is asked to explain, again, why the holding company exists. She explains. Six weeks later the business accounts are given notice anyway. Complexity, in the compliance world, is not assessed. It is priced, and the price is often the exit.
The crypto-adjacent customer. A client sold a modest crypto position in 2021, fully declared, taxes paid, funds received from a regulated exchange. Years later, a routine screening tool flags the historic inflow, and the account review that follows ends the relationship. The bank never alleges wrongdoing. It simply declines to carry the category.
What unites these cases is that in none of them was the customer accused of anything. There was no investigation to answer, no allegation to rebut. There was only a risk score that crossed an invisible threshold.
What Is Actually Documented
I want to separate what I see in practice from what is publicly verifiable, because this subject attracts exaggeration from all sides.
The de-banking debate broke into the open in the United Kingdom in the summer of 2023, when Nigel Farage announced that Coutts, the private bank owned by NatWest, was closing his accounts. Initial reporting suggested he had simply fallen below the bank's wealth threshold. Farage then used a subject access request to obtain the bank's internal file on him: roughly forty pages in which the reputational implications of his political views featured prominently alongside the commercial analysis. The NatWest chief executive, Dame Alison Rose, resigned after admitting she had discussed his account with a journalist, and the chief executive of Coutts followed her out the door a day later.
Whatever you think of Farage, the episode mattered, because it forced the regulator to look at the whole phenomenon. The Financial Conduct Authority collected data from 34 firms covering the overwhelming majority of the UK current account market. Its initial findings, published in September 2023, reported that no firm had closed an account primarily because of a customer's political views in the period examined, and that the most common stated reasons for closures were dormant accounts and financial crime concerns. The follow-up work was more revealing in a quieter way: the FCA found that firms were often poor at categorising and documenting why accounts had actually been closed. In other words, the banks themselves frequently could not demonstrate, cleanly, why a given customer had been exited. Anyone who has tried to get a straight answer out of a bank's exit team will recognise that finding.
The regulatory response is now arriving. The UK government has introduced rules requiring at least 90 days' notice of account closure, together with an explanation of the reasons and signposting to the Financial Ombudsman, applying to accounts opened from late April 2026, with carve-outs where money-laundering rules or suspicion of serious crime are involved. That is genuine progress, though note the shape of it: more notice and more explanation, not a right to keep the account.
Elsewhere the picture varies by country, and I will keep this qualitative because the details shift. In Germany, banks can generally end an ordinary current account relationship with a couple of months' notice and no particular justification, while the statutory basic account enjoys much stronger protection and can only be terminated on narrow legal grounds. Other European countries sit somewhere along the same spectrum: freedom of contract for the bank as the default, with a thin statutory floor guaranteeing basic access. The floor keeps you off the pavement. It does not preserve the banking relationship your life was built on.
The Defence: The Three-Account Principle
Now to the part that actually matters, because you cannot litigate your way out of a spreadsheet decision. You can only make yourself resilient to it.
I give every client the same baseline rule, and I hold to it myself. I call it the three-account principle, and it has three legs.
Never only one bank. However good the relationship, however long the history. The second account is not a convenience. It is the insurance policy that turns a de-banking letter from a crisis into an administrative nuisance.
Never only one country. A second account at another domestic bank protects you from one institution's risk appetite. It does not protect you from a sector-wide policy shift, a national regulatory panic, or a change in how your entire customer category is scored in that market. Genuine resilience means at least one functioning account in a second jurisdiction, opened and tested before you need it. I have written about the realistic options, from Singapore to the UAE to the United States, and about the trade-offs between Switzerland and Singapore at the private banking level. The right second jurisdiction depends on your profile. Having one at all is the non-negotiable part.
Never all payment flows through one provider. This is the leg people forget. If your salary, your mortgage, your card spending, and your business receivables all route through a single institution, then that institution holds your entire operational life hostage, whatever your account balances elsewhere. Spread the flows. Keep a card issued by a different provider. If you run a business, keep a second merchant and payment rail warm. The colleagues at freedombanking.plus have written a good piece on what a UK de-banking actually looks like from the inside, and the operational chaos it describes is exactly what the third leg is designed to prevent.
Redundancy looks inefficient right up until the Tuesday the letter arrives. Then it looks like the cheapest insurance you ever bought.
Talking to Compliance Without Hurting Yourself
A large share of avoidable de-banking happens not because of what the customer is, but because of how the customer responds to questions.
When a bank asks about source of funds or the purpose of a transaction, it is not making conversation. Someone is filling in a file, and the file gets scored. So: answer promptly, answer completely, answer in writing, and answer boringly. Provide documents rather than narratives. Make sure the story you tell one institution matches the story you told the last one, because inconsistency is itself a flag. Never be clever, never be indignant, and never treat the questionnaire as an insult to be handled with sarcasm. I have watched clients talk themselves out of a salvageable relationship in two ill-tempered emails.
And structure your affairs so that they are explainable in one paragraph. If your own adviser needs a whiteboard to explain why your money moves the way it does, a junior compliance analyst with eight minutes per file has no chance, and the ambiguity will be resolved against you. The same logic applies whether you bank in London, in Southeast Asia, or anywhere else: the account survives on the quality of its paper trail.
When to Fight, When to Walk
Finally, the triage question I run through with clients when the letter has already arrived.
Fight when there is something to win. If the closure would leave you without basic banking access in your home country, use every statutory protection available, and use the ombudsman route where it exists. If the stated reason is demonstrably false, or the notice period is shorter than the rules allow, push back in writing and escalate. The new UK regime, with its notice and reasons requirements, will make this kind of challenge more feasible than it used to be.
Walk when the relationship is dead. If a bank has decided, at policy level, that your category is unwanted, no complaint letter reverses that. You might win an extension. You will not win back a home. Worse, if the closure sits anywhere near a financial crime suspicion, the bank is legally barred from telling you so, and you can burn months fighting a decision whose real basis nobody is permitted to explain. Take the notice period, execute the move you should have prepared years earlier, and treat the episode as the tuition fee for a lesson in redundancy.
The deeper point is this. Banking has quietly stopped being a right and become a subscription that the provider can cancel. You cannot change that by being a good customer, because good customers are fired every day for reasons of arithmetic rather than conduct. You change it by making sure that no single institution, in no single country, can switch off your financial life.
Build the redundancy now, while every door is open and nobody is asking urgent questions. It is the one piece of advice in this field that has never once been wrong.
