How to survive a bank closing your business account

The worst thing that happens to our clients is rarely a tax assessment or a regulatory enquiry. It is an email from a bank giving thirty days' notice of account closure, with no reason stated and no appeal. Payroll is due in nine days. Suppliers are on direct debit. The business is solvent, profitable and entirely legitimate, and it has one bank account.

This guide is about making that email survivable.

Why do banks close accounts for good businesses?

Usually it's the bank's decision about its own business, not a verdict on you. None of the reasons below are about how you behaved, and none of them can be argued with from outside.

Here's what typically happens:

• A bank that passes payments between countries (a "correspondent bankCorrespondent bankA bank that holds accounts for other banks and processes payments for them, often in US dollars or euros.") pulls out of a route.
• A compliance review moves your type of business into a different category.
• A country moves up an internal risk list.
• The bank decides your account earns too little to justify the cost of monitoring it.

So the reason you were banked can vanish without any change on your side. That makes backup a design question, not a question of whether your bank trusts you.

What is the three-layer setup?

We set up banking for clients in three layers. Think of it as a spare tyre, a spare set of keys and a taxi number: dull until the day you need them.

Layer one: the main operating bank. A real bank, in the country where your business has genuine substance (real people, premises and activity). It holds your main balance and your payroll. This is the relationship you invest in:

• Meet your relationship manager once a year.
• Tell them about big changes before they ask.
• Keep your transactions clean and predictable.

Layer two: the backup bank. A second bank in a different country, using a different correspondent network. It holds two to three months of running costs and has a live payment mandate (the signing authority that lets you actually send money).

The different country matters. Two accounts at two UK banks both depend on the same regulator and the same sanctions stance. They often rely on the same correspondent for US dollars too.

Layer three: payment apps. One or two e-money institutionsEMI (electronic money institution)A licensed firm that can issue e-money and run payment accounts, such as many app-based business accounts. (EMIs) or payment institutions, which are the app-style providers for collecting payments, changing currency and paying suppliers. They're quick to open, cheap to run and easy to lose. That's exactly why they should never be your layer one or two.

Which pairs of countries work well together?

Choose the pairing on purpose. These combinations work in practice for groups trading across borders:

Watch out if US dollar payments are critical to your business. Avoid two accounts that both clear dollars through the same correspondent. If both banks use the same one, a single decision by that correspondent takes out both.

What does a backup bank cost?

Be honest about this with your board. A second full banking relationship typically costs:

• Opening the account and due diligence: 4,000 to 15,000 in professional and bank fees, depending on the country and how complex you are.
• Ongoing minimum balance or relationship fees: often 1,000 to 6,000 a year. Sometimes this is a minimum deposit rather than a fee.
• Your own time: an annual review pack, plus keeping two sets of records up to date.

Now weigh that against thirty days of frozen operations. For any business with payroll above a modest level, the sums aren't close.

How do you keep the second account alive?

A dormant account is a closed account waiting to happen. Banks close relationships that generate no activity, because they can't recover the cost of monitoring them. So:

• Use it properly. Run a genuine share of your flow through it: 10 to 20% of volume, not a token monthly transfer.
• Keep the mandate current. Directors change and signatories lapse. If your mandate needs a signature from someone who left in 2024, it isn't a live account.
• Refresh your KYCKYC (know your customer)The checks a bank or provider must do on who you are, who owns your company and what you'll use the account for. early. KYC ("know your customer") is the identity and background checks banks repeat regularly. Do it at each anniversary instead of waiting to be asked.
• Tell both banks together. When something material changes, tell the backup bank at the same time as the main one.

What should be in your document pack?

Keep one pack, kept current, that you can send to any institution within a day:

1. Certificate of incorporation, memorandum and articles, and current register extracts.
2. An ownership chart down to the ultimate beneficial ownersBeneficial owner (UBO)The real person who ultimately owns or controls a company or trust, behind any chain of companies. (UBOs, the real people who own the business), with percentages.
3. Passport, proof of address and source-of-wealth evidence (how they came by their money) for each UBO and director.
4. The last two years of financial statements, plus current-year management accounts.
5. A business description, your top counterparties and expected monthly volumes by currency.
6. Licences or regulatory permissions where your activity requires them.

Groups that keep this pack current open accounts in weeks. Groups that rebuild it from scratch each time take months. They usually rebuild it during the thirty-day notice period, which is the worst possible moment.

What should you do the day a closure notice arrives?

FAQs

Is two accounts enough?

Two banks plus one payment app is the minimum for a trading business. Groups with several operating companies usually need more, set up per company rather than per group.

Should the second account be in the same currency?

It should be able to hold and settle your main operating currency. But it shouldn't depend on the same clearing route (the chain of banks that carries the payment) to do it.

Do EMIs count as backup?

Partly. They're excellent for keeping payments moving and poor for holding balances or supporting credit. Count them as layer three only.

We're pre-revenue. Is this premature?

Open the second account when you open the first, while your story is still simple. It gets harder as the business gets more complicated, not easier.
