Many businesses think about banking in terms of accounts. However, a resilient business thinks about banking in terms of infrastructure.
That distinction matters. Having three IBANs does not automatically make a company resilient if all three ultimately depend on the same provider, banking partner or payment route.
In 2026, a better question is: if one part of our financial infrastructure stopped working tomorrow, could the business still operate?
That is the principle behind a resilient banking setup.
Build Around Financial Functions
A resilient banking setup for businesses means maintaining essential financial operations when something goes wrong.
The concept closely resembles the approach taken by the Bank of England on operational resilience operational resilience: organisations should understand their critical services, identify dependencies and prepare for disruption rather than assuming disruption will never happen.
For a normal company, those critical financial functions might include collecting customer revenue, paying salaries, settling supplier invoices, issuing refunds and accessing working capital.
The goal is not to eliminate banking risk.
It is to prevent one failure from becoming a company-wide crisis.
Stop Thinking in Terms of a “Main Bank”
A resilient banking setup replaces the single main bank model with a network of purposeful relationships.
One bank receives revenue, stores cash, pays suppliers, runs payroll and provides corporate cards.
It is convenient. But it also creates concentration risk.
A resilient structure separates these functions.
For example, a company might maintain one relationship for everyday operations, another for selected international payments and a separate arrangement for merchant settlement.
This does not mean constantly moving money between accounts. Each relationship should have a genuine operational purpose.
Think of the banking structure as a network rather than a single account.
Build a Resilient Banking Setup Around Financial Functions
Before opening additional accounts, map how money actually moves through the business.
Start with four questions:
Where does money enter?
Customer transfers, card payments, marketplace settlements and other revenue channels should be identified.
Where is money held?
Determine where operational cash, reserves and tax liabilities are maintained.
Where does money leave?
Map payroll, suppliers, refunds, taxes and recurring expenses.
Which payments cannot stop?
A delayed software subscription is inconvenient. Missing payroll or a critical supplier payment can be far more serious.
This exercise reveals where the real vulnerabilities sit.
Create a Primary Operating Layer
Most businesses still need a primary banking relationship.
This is where routine financial activity takes place: customer receipts, supplier payments, payroll and day-to-day expenses.
The provider should understand the company’s actual business model.
If the company trades internationally, the bank should know its principal markets, currencies, expected turnover and typical counterparties.
Trying to make the business appear simpler than it really is can undermine resilience. The strongest primary relationship is usually one where the financial institution understands what the company actually does.
Add a Genuine Secondary Rail
A secondary account should not exist merely so the company can say it has two banks.
It needs to be usable.
That means completing onboarding properly, keeping company information current and occasionally testing permitted functionality so authorised staff understand how it operates.
The secondary relationship may become important during an outage, account migration or other disruption affecting the primary provider.
Crucially, it should not be treated as a way to circumvent restrictions imposed by another institution.
Its purpose is continuity.
Separate Settlement From Operations
For businesses processing significant payment volumes, settlement deserves separate attention.
A merchant might generate £500,000 in monthly card sales. But have those proceeds routed through a single processor before reaching one operational account?
On paper, the company has a bank and a payment processor.
Operationally, however, its revenue may still depend on one settlement chain.
Understanding where funds travel between the customer and the company’s usable balance is therefore essential.
Businesses should know which institutions participate in that chain and what happens if settlement is delayed.
Don’t Keep Every Pound in the Same Place
Banking resilience also concerns liquidity.
Consider a company with £600,000 available but £580,000 held through one financial relationship.
Technically, it is well funded.
Operationally, access to most of its liquidity depends on one institution.
Businesses should consider how much accessible cash they need to continue essential operations during a disruption.
The appropriate amount will differ significantly between companies. A payroll-heavy consultancy has different requirements from an e-commerce merchant with large refund obligations.
The principle is simple: cash is only useful operationally when the business can access it when required.
Understand the Difference Between Banks and EMIs
Not every business account represents the same financial relationship.
A traditional bank account and an account provided by an Electronic Money Institution can operate differently, particularly regarding how customer funds are protected.
The European Commission’s DORA regulation has significantly strengthened requirements around operational resilience and third-party risk management.
Companies should understand:
- Which legal entity provides the account
- How customer funds are protected
- Whether funds are deposits or safeguarded electronic money
- Which regulator supervises the provider
- Whether another institution sits behind the service
- How settlements reach the account
The brand visible on the dashboard does not necessarily reveal the entire financial infrastructure underneath it.

Look for Hidden Concentration
This is where resilient banking becomes more interesting.
Imagine a company has:
Bank A + EMI B + payment platform C.
It appears diversified.
But suppose EMI B and platform C both rely on the same underlying banking partner for an important part of their infrastructure.
The company may have three interfaces but fewer genuinely independent financial relationships than expected.
The same issue can occur with payment processors, acquiring banks, correspondent banks and technology providers.
Resilience therefore requires looking one layer deeper.
Ask not only “How many providers do we have?”
Ask “Where do these providers depend on the same infrastructure?”
Match Providers to Their Jobs
A resilient banking setup does not require each provider to do everything.
In fact, specialisation can be useful.
One institution may be excellent for domestic payments.
Another may provide stronger multi-currency capabilities.
A separate provider may handle merchant acquiring.
The objective is to allocate financial functions intelligently rather than searching endlessly for one supposedly perfect global bank.
This also makes future changes easier. Replacing one component is less disruptive when the entire financial operation is not built around it.
Create a Banking Continuity File
Resilience is not only about accounts.
It is also about how quickly the business can respond.
Maintain an internal banking continuity file containing current information such as:
- Banking relationships and account purposes
- Authorised users
- Payment approval procedures
- Key provider contacts
- Beneficial ownership documents
- Recent corporate records
- Major customer and supplier contracts
- Expected transaction volumes
- Emergency payment responsibilities
Access should be appropriately controlled because this documentation contains sensitive information.
If disruption occurs, management should know who contacts the provider, who manages urgent payments and who communicates with suppliers.
Improvising these decisions during a crisis wastes valuable time.
Test the Setup Before Something Breaks
A backup that has never been tested is only a theory.
Businesses routinely test data backups and cybersecurity systems. Banking infrastructure deserves similar attention.
Management can periodically model scenarios such as:
What happens if our primary bank is unavailable for 48 hours?
Is payroll still possible to complete?
Are customers able to continue paying?
Will refunds still be processed on time?
Who has authority to use the secondary account?
Would finance staff know what to do?
This does not require deliberately disrupting live banking relationships. It means testing the procedures around them.
Weaknesses discovered during a simulation are considerably cheaper than weaknesses discovered on payroll day.
Resilience Should Grow With the Business
A £100,000-turnover consultancy does not need the same banking architecture as a multinational processing millions across several currencies.
Complexity should follow risk.
As transaction volumes increase, businesses can reassess their exposure to individual banks, processors, currencies and settlement channels.
International expansion should trigger another review.
Entering the US, Middle East or Asia may change payment flows substantially. The banking structure that supported a UK-only business may no longer suit a company operating across four regions.
Banking architecture should therefore evolve alongside the commercial model.
The 24-Hour Banking Test
Use this test to determine whether your resilient banking setup would actually protect the business.
Imagine receiving this message tomorrow morning:
“Your primary financial account is temporarily unavailable.”
Now consider the following questions in relation to the next 24 hours:
Are customers still able to pay?
Will employees receive their salaries on time?
Do critical suppliers have a way to receive funds?
Can the finance team access enough liquidity?
Will merchant settlements continue without interruption?
Does management know who needs to act?
If most answers depend on one institution returning to normal, the company does not yet have meaningful banking resilience.

Frequently Asked Questions
A resilient banking setup is financial infrastructure designed so that the failure of one component does not stop the business from operating. Rather than relying on a single bank for all financial functions, a resilient structure separates critical activities — such as revenue collection, payroll, supplier payments and merchant settlement — across genuinely independent providers. In 2026, this approach has become increasingly important as businesses face account freezes, provider outages and unexpected compliance reviews.
There is no universal answer — resilience is about function, not quantity. Having three accounts with the same underlying banking infrastructure provides less genuine resilience than two accounts with truly independent providers. The key questions are whether the business can collect revenue, pay employees and settle critical suppliers if one provider becomes temporarily unavailable. Complexity should follow risk — a small consultancy has different needs from a multinational processing payments across multiple currencies.
Banking concentration risk arises when too much of a company’s financial activity depends on a single institution, payment route or underlying banking partner. This can be less obvious than it appears — two seemingly different providers may both rely on the same correspondent bank or payment infrastructure. Businesses can reduce concentration risk by mapping how money enters, moves through and leaves the company, then allocating financial functions across providers with genuinely independent infrastructure rather than simply opening additional accounts with related entities.
A traditional bank account and an account provided by an Electronic Money Institution operate differently, particularly regarding how customer funds are protected. Bank deposits may benefit from deposit guarantee schemes, while EMI funds are typically safeguarded through segregated arrangements. The brand visible on a dashboard does not always reveal the full financial infrastructure underneath. Understanding which legal entity provides the account, how funds are protected and which regulator supervises the provider is essential when building genuine resilience.
A useful approach is to model realistic disruption scenarios — for example, imagining that the primary bank is unavailable for 48 hours and asking whether payroll can still be completed, customers can still pay, refunds can be processed and critical suppliers can receive funds. This identifies weaknesses in procedures and access arrangements before they arise in practice. Businesses should also maintain a banking continuity file containing account purposes, authorised users, key contacts and emergency payment responsibilities so that management can respond quickly without improvising under pressure.
Bottom Line
A resilient banking setup is not about collecting bank accounts.
It is about designing financial infrastructure so that the failure of one component does not stop the company.
Start by mapping how money enters, moves through and leaves the business. Separate critical functions where appropriate, maintain genuinely usable secondary relationships and understand the institutions behind payment and settlement channels.
Then test the architecture against realistic disruption.
The strongest setup is not necessarily the one with the most providers. It is the one where every relationship has a clear purpose, dependencies are understood and the business can continue operating when something unexpected happens.
For international companies, this is becoming an increasingly important part of financial risk management.
