I have spent a long time arguing that banking is moving through a much more fundamental transition than many incumbents seem willing to acknowledge. For years, my view has been that the future of banking will increasingly be shaped by platforms, and that embedded finance, neobanks and now agentic banking are steadily turning that from theory into reality.
I also think parts of the European banking industry remain far too comfortable with their current position. There is still a tendency to assume that scale, regulation, customer inertia and historic relationships will continue to protect the dominant players much as they always have. I am not convinced that assumption will hold indefinitely.
After enough conversations around exactly this point, I decided it was time to stop relying on instinct and experience alone and actually sit down with the numbers. I wanted to test my own assumptions, challenge some of the predictions I have been making, and see whether the available evidence genuinely supports the direction of travel I have been talking about.
That is what this analysis is.
What follows is one person’s interpretation of the data that is currently available, mixed with a fair amount of personal experience from working in and around banking, technology and transformation for more years than I care to count.
It is certainly not investment advice, competitive intelligence or a glimpse into Revolut’s boardroom. I am looking at what Revolut is doing, what has happened in other markets, how Finnish banking works today, and then trying to connect the dots.
Some of those dots may turn out to have been connected correctly. Others may prove to have been nowhere near each other.
I could therefore be completely wrong about parts of this. Revolut may move faster than I expect, slower than I expect, or in a completely different direction. Finnish banks may respond far more aggressively than I anticipate, or customers may behave differently from the patterns we have seen elsewhere.
That uncertainty is part of the reason for doing the work now. The question is whether the signals already visible are strong enough that Finnish banks should be paying serious attention to what might happen next.
I have deliberately kept the analysis focused on Finland. The Nordic market as a whole deserves its own treatment because the competitive dynamics, incumbent structures and customer behaviours differ materially across Sweden, Norway, Denmark and Finland. That may well be the next piece of work.
For now, this is the Finnish view.
Only time will tell how much of it survives contact with reality.
Revolut is no longer testing the Finnish market from the sidelines. In August 2026, Revolut Bank UAB applied to establish a Finnish branch. If approved, the branch would allow Revolut to issue Finnish FI-prefixed IBANs and integrate more naturally into salary payments, bills and everyday banking. Revolut says it already has more than 250,000 customers in Finland. That is a surprisingly large number. It is already greater than the more than 200,000 private and corporate customers reported by Oma Savings Bank. But the comparison needs care. Revolut does not disclose how many of those Finnish customers are active, receive their salary into Revolut, hold meaningful deposits there, or regard it as their primary bank.
In my view this is important because the immediate threat to Finnish banking is easy to exaggerate. Finland has €115.2 billion of household deposits and €140.9 billion of household bank loans. OP alone has around 2.1 million owner-customers and, according to Bank of Finland market-share data, around 41 per cent of Finnish deposits and 34 per cent of loans. Nordea operates from a Nordic balance sheet and currently expects a cost-to-income ratio excluding regulatory fees of 44–45 per cent for 2026. Finnish banks remain well capitalised, and both the Bank of Finland and FIN-FSA describe the sector as resilient. Revolut is nowhere close to destabilising that structure today.
Yet that is probably the wrong way to frame the threat.
Revolut does not need to persuade a Finnish family to close its OP or Nordea account and refinance its mortgage. It can damage incumbent economics while the customer formally remains with the incumbent. Payments can move first. Then travel spending, foreign exchange, subscriptions, savings, investments and eventually unsecured lending. Salary can follow once the local IBAN arrives. The mortgage may remain exactly where it was. What changes is how much of the customer’s financial activity, data and attention still passes through the traditional bank.
My base case is therefore neither that Revolut will dominate Finnish banking nor that it will remain a niche travel card. A reasonable seven-year scenario is approximately 750,000 Finnish customers by 2033, perhaps €3 billion of Revolut-linked balances and erosion of around 2–3 per cent of the addressable retail revenue pool of incumbents. The aggregate numbers are manageable. Their distribution will not be. A 2–3 per cent revenue loss, with costs initially unchanged, can worsen a bank with a 45–60 per cent cost-to-income ratio by roughly 0.9–1.9 percentage points. The pressure would be greatest on banks whose propositions are difficult to distinguish from larger universal banks but whose technology, compliance and distribution costs are spread across far fewer customers.
There is also an important correction to the current narrative. Revolut has not applied for a separate Finnish banking licence or Finnish bank charter. It has applied to establish a Finnish branch of the Lithuanian-licensed Revolut Bank UAB. Prudential supervision therefore remains principally with its home-state framework and the ECB, while FIN-FSA has host-country responsibilities. Deposits in an eventual Finnish branch would remain under the home-country deposit-guarantee framework rather than becoming deposits of a separately licensed Finnish bank.
The strategic implication is nevertheless significant. Revolut is removing one of the remaining pieces of friction between being an app that Finns use and being a bank that Finns bank with.
Revolut is already much further into Finland than it appears
The most important number is the one we do know, more than 250,000 Finnish customers as of August 2026. The number we do not know is arguably even more important. Revolut has not published Finnish active-user numbers, average balances, salary-account penetration, lending volumes, deposits or revenue. Consequently, claims that Revolut already has a particular Finnish banking market share would be speculation.
Customer numbers also mean different things at different banks. S-Bank reported 858,000 active customers at the end of 2025. OmaSp says it serves more than 200,000 private and corporate customers. OP talks about owner-customers. Revolut’s 250,000-plus figure appears to be customers registered with the platform. These populations cannot simply be placed in a league table and treated as equivalent economic relationships.
Still, 250,000 is not trivial. Revolut has acquired that population before it has a Finnish IBAN.
Technically, an LT-prefixed Lithuanian IBAN already works within SEPA, and Revolut itself points out that EEA IBANs should be treated equally for SEPA transfers. In practice, a domestic IBAN removes behavioural and operational friction. It looks familiar to employers, customers and accounting systems, and it makes the proposition feel domestic. Revolut’s Finnish branch application explicitly links FI IBANs with receiving salary, paying bills and making Revolut more useful for everyday banking.
That tells us rather more about Revolut’s intention than the licence application itself. The objective is no longer simply Finnish acquisition. It is relationship deepening.
Globally, Revolut now says it has more than 80 million retail customers. At the end of 2025 it had 68.3 million retail customers and 767,000 business customers, with approximately €57.5 billion of customer balances. Revenue reached approximately €5.3 billion and pre-tax profit €2.0 billion, producing a 38 per cent pre-tax margin. Transactions per customer increased by 24 per cent, while the number of people treating Revolut as their primary account increased by 45 per cent during the year.
The revenue mix is also important. Revolut generated approximately €1.17 billion from card payments, €0.83 billion from subscriptions, €0.77 billion from wealth and €0.71 billion from foreign exchange in 2025, while Revolut Business represented 16 per cent of income. Customer lending was still only around €2.5 billion, even after growing 120 per cent, and around 90 per cent of group assets remained in cash, cash equivalents and Treasury investments. Revolut therefore enters Finland with economics quite different from a conventional Finnish mortgage-heavy retail bank.
Revolut reports in GBP. EUR equivalents have been calculated using ECB 2025 average exchange rates for income-statement figures and the 31 December 2025 exchange rate for balance-sheet figures.
That is why I would be cautious about assuming that Revolut must take Finnish mortgages to succeed. Mortgages may eventually matter, but they do not have to come first.
How Revolut really compares with Finnish banks
The following comparison deliberately mixes fewer numbers than a conventional banking league table. That is because the publicly disclosed numbers are not fully comparable. Nordea does not publish a directly equivalent Finland-only retail customer count in its group reporting, Revolut does not disclose Finnish deposits or loans, different Finnish banking groups define customers and cost-to-income differently. Pretending those inconsistencies do not exist would create precision without accuracy.
Provider
Customer / relationship scale
Balance-sheet and funding signal
Cost and profitability signal
Strategic position
Revolut
>250,000 in Finland; 68.3m global retail customers at end-2025, now >80m globally
Finnish balances and lending not disclosed. Globally approximately €57.5bn customer balances versus €2.5bn lending; c.90% of assets in cash, equivalents and Treasury investments
No directly comparable banking C/I ratio published. 2025 PBT margin 38%
Global platform spanning payments, FX, subscriptions, wealth and increasingly credit, with a very low physical distribution burden.
OP Pohjola
About 2.1m owner-customers
Bank of Finland market-share data shows c.41% of Finnish deposits and 34% of loans
Large-scale economics, although the group includes both banking and insurance, making simple comparisons with Revolut misleading
Strongest domestic ecosystem: banking, mortgages, insurance, wealth, owner benefits and local cooperative relationships.
Nordea
Finland-only customer count not disclosed on a directly comparable basis
Large diversified Nordic balance sheet; mortgages, household deposits, corporate banking and wealth
Scale already comparable with international competition, broad corporate and wealth franchise and strong efficiency.
S-Bank
858,000 active customers at end-2025
€10.2bn deposits, €9.4bn lending, €8.9bn assets under management
2025 C/I 68%; ROE 8.2%
Strong daily-banking engagement through the S Group ecosystem; proposed OmaSp transaction adds scale and broader lending/customer relationships.
OmaSp
>200,000 private and corporate customers
Retail, mortgage and SME-focused balance sheet; exact figures vary with reporting period and are not reproduced here as directly comparable data
Recent public performance has also been affected by bank-specific factors, so a simple peer C/I comparison would mislead
Strong personal-service and local-relationship proposition; proposed acquisition means its standalone future is now uncertain.
Savings Banks Group
Network of local savings banks rather than one uniform customer franchise
Predominantly traditional retail banking, saving, investment and lending relationships
Smaller scale means digital and regulatory investment must be spread over a narrower base
Locality and personal service are genuine differentiators, although expensive digital parity is harder to fund at smaller scale.
Aktia
Smaller national franchise with particular strength in wealth and affluent/customer relationships
Banking supplemented by asset management and life insurance
H1 2026 comparable C/I 61%; comparable ROE 15.6%
More diversified fee and wealth economics than a pure savings bank, which gives some protection from payment commoditisation.
The table also challenges one assumption I made going into the research, we cannot demonstrate from public figures that Revolut’s cost-to-income ratio is “far better” than every Finnish bank.
It may well have a lower marginal cost of serving an additional digital customer. It has no Finnish branch estate, one technology platform distributed across tens of millions of users and significant non-interest income from payments, subscriptions, FX and wealth. Its 38 per cent pre-tax margin is extremely strong. But a pre-tax margin is not a banking cost-to-income ratio. Comparing that 38 per cent directly with Nordea’s 44–45 per cent C/I excluding regulatory fees, S-Bank’s 68 per cent or Aktia’s 61 per cent would be analytically wrong.
There is another complication. Revolut’s current balance sheet is much less credit-intensive than those of traditional Finnish banks. Finnish incumbents carry the costs, capital, credit-risk infrastructure and funding associated with large mortgage and corporate loan books. Revolut currently earns a much larger proportion of its revenues from activities that require comparatively little balance-sheet deployment. Its apparent efficiency is therefore partly architecture and partly business mix.
Seen this way, the source of the competitive pressure becomes much clearer.
The strategy is visible because Revolut has used it before
Revolut’s likely Finnish strategy does not require much imagination. Versions of it are already visible elsewhere in Europe.
Romania provides perhaps the clearest example. Revolut established a local branch, began migrating more than four million customers to Romanian IBANs and explicitly described the objective as meeting more of customers’ financial needs and becoming their primary bank. In Germany, after reaching two million customers and introducing German IBANs, Revolut said its local offering would expand towards credit cards, overdrafts and mortgages, using local talent to tailor lending to the market. Ireland shows the next stage where Revolut offers personal loans of up to €30,000, credit cards and Pay Later products through its local operation.
Finland is unlikely to follow exactly the same product sequence, but the direction is clear.
Here is a potential roadmap for Revolut in Finland.
This is a forecast rather than a published Revolut roadmap, but it follows the sequencing used in Romania, Germany and Ireland and the stated Finnish objective of enabling local everyday banking.
I would expect the first serious Finnish battle to be around the salary account, deposits and daily spending, rather than mortgages.
Once salary lands in Revolut, the economics of the customer relationship change. Revolut can see cash flow, spending patterns and recurring commitments. It becomes easier to sell paid subscriptions, savings, investments and credit. Its loyalty programme can reinforce card usage. And because the company already monetises payments, subscriptions, wealth and FX at considerable scale globally, it does not have to wait for a large mortgage book before the Finnish customer becomes economically interesting.
SMEs are another area that deserves more attention. Revolut Business accounted for 16 per cent of group income in 2025. Finnish companies trading internationally, technology businesses, freelancers and smaller import/export businesses can be attractive targets because FX, cards, transfers, expense management and multi-currency accounts solve problems that are more visible than the difference between two domestic current accounts.
Mortgages will probably come later, if they come aggressively at all. Revolut started mortgage refinancing in Lithuania in 2025 and has signalled mortgage ambitions in markets such as Germany. Yet Finland is a relatively low-margin mortgage market in which incumbents already have deep credit data, collateral processes, customer relationships and funding machinery. Revolut may eventually want mortgages because they anchor primary relationships, but taking a large Finnish mortgage share is not a prerequisite for disrupting Finnish retail banking.
The real threat is fragmentation, not wholesale switching
For decades, bankers have tended to measure competition through customer acquisition and attrition.
Did the customer leave?
Which bank became the primary bank?
That metric increasingly misses what is happening.
Consider a customer whose salary still arrives at Nordea. The mortgage remains there because refinancing offers no compelling advantage. Online banking credentials remain useful for Finnish identification. But the customer sends €1,500 every month to Revolut, uses Revolut for almost every card transaction, holds travel money there, invests through it and later takes a small consumer loan. Nordea can continue to classify that person as a customer, perhaps even a primary customer, while losing transaction data, interchange economics, investment fees, deposit spread and daily engagement.
Finland gives incumbents some meaningful protection. Finance Finland has previously estimated that more than 90 per cent of strong electronic authentication in Finland was conducted using online banking credentials, making the bank relationship part of the broader digital infrastructure of everyday life. Mortgages, insurance, household finances, e-invoicing and local service relationships create additional friction around full switching. Those advantages are real, although European digital identity initiatives may gradually reduce the uniqueness of bank-based identification.
This is also why Revolut’s branch application should not be confused with obtaining a Finnish banking charter. Revolut Bank UAB remains a Lithuanian bank supervised within the European banking framework and directly by the ECB as a significant institution. FIN-FSA’s supervision of a Finnish EEA branch is more limited, with home-state authorities retaining responsibility for areas such as prudential risk and solvency. A Finnish branch would nevertheless assume local reporting, conduct and regulatory obligations.
The deposit-guarantee arrangement may also matter at the margins of customer perception. Deposits at a Finnish branch of Revolut Bank UAB would remain covered by the Lithuanian deposit-guarantee scheme, rather than moving into the Finnish scheme. Under the EU cross-border framework, the host-country deposit-guarantee system assists with local payout on behalf of the home-country scheme in the event of a failure. That should not be exaggerated into a safety problem, but Finnish incumbents retain a potentially useful trust advantage if they communicate it responsibly rather than using fear as a competitive tool.
What the next seven years could look like
Forecasting exact market share for a business growing as quickly as Revolut would be false precision. The scenarios below are therefore deliberately constructed as stress ranges rather than point forecasts. They begin with the disclosed Finnish base of more than 250,000 customers in 2026 and the Bank of Finland’s €115.2 billion household-deposit stock at December 2025. The revenue numbers represent addressable incumbent retail revenue erosion, not Revolut’s accounting market share.
Scenario
Finnish customers in 2029
Finnish customers in 2033
Revolut-linked balances by 2033
Incumbent retail revenue erosion by 2033
Mechanical C/I effect if costs do not adjust
Incumbent best case
~350,000
~450,000
~€0.7bn, c.0.6% of today’s household deposits
~0.5–1%
roughly +0.2 to +0.6 percentage points
Likely case
~500,000
~750,000
~€3.0bn, c.2.6%
~2–3%
roughly +0.9 to +1.9 points
High-disruption case
~700,000
~1.0m
~€6.0bn, c.5.2%
~5–7%
roughly +2.4 to +4.5 points
The C/I ranges are a sensitivity calculation using starting cost-to-income ratios of 45–60 per cent and assuming the relevant revenue disappears before costs are reduced. Real banks would, of course, react. The purpose is to show why apparently modest revenue leakage matters in a high-fixed-cost business. The balance scenarios are gross Revolut-linked customer balances, not a claim that every euro would represent a euro withdrawn from an incumbent Finnish deposit account.
The likely scenario would require Revolut to grow its Finnish customer base to roughly three times the disclosed 250,000-plus starting level over seven years. That is demanding, but materially slower than Revolut’s recent global growth. Its worldwide retail customer base increased by 30 per cent during 2025, while customer balances grew 66 per cent. Finland’s already mature digital-banking market is a reason to assume slower penetration than Revolut has achieved in some less digitally consolidated markets.
The deposit numbers also put the threat into perspective.
Even the high-disruption scenario amounts to around €6 billion, or approximately 5.2 per cent of the December 2025 household deposit stock. That would be strategically uncomfortable, particularly if concentrated among younger and higher-income customers, but it would not amount to a run on Finnish banking. The Bank of Finland and FIN-FSA continue to assess Finnish banks as well capitalised and resilient to severe shocks.
The larger impact may arrive before those balance shifts. Revolut can change the market price of convenience.
If it offers a credible free daily account, inexpensive international payments, attractive savings, integrated investments, travel benefits and increasingly competitive lending within one app, incumbents may have to respond before they actually lose many customers. Deposit rates rise. Card and payment fees come under pressure. Premium packages need more benefits. Technology investment increases. Loyalty economics become more expensive. Customer service expectations rise.
In other words, Revolut can hurt Finnish banking margins through competitive behaviour even when its own market share remains relatively modest. That is the part of the threat that simple customer-count forecasts miss.
S-Bank and OmaSp change the Finnish competitive geometry
The timing of S-Bank’s proposed acquisition of Oma Savings Bank is therefore interesting, although it would be wrong to describe the transaction as a response to Revolut.
On 9 July 2026, S-Bank and OmaSp entered a combination agreement under which S-Bank launched a recommended €17.20-per-share cash tender offer, valuing the equity at approximately €571 million. S-Bank received the required merger-control clearance from the Finnish Competition and Consumer Authority on 27 August. As of 5 September, the offer remains open and is scheduled to expire on 25 September unless extended. Completion remains conditional on the remaining regulatory approvals and other offer conditions, including the acceptance threshold, with completion still expected during the fourth quarter of 2026.
S-Bank’s explanation is revealing. It says the combination would move the bank into a new size category, improve its ability to invest in services and technology, and support expansion of corporate banking. That argument exists independently of Revolut, but it also captures one of the fundamental competitive questions facing smaller Finnish banks, how much scale is required to support the technology, compliance, cyber-security, data, AI, payments and customer-experience investment expected of a modern bank?
S-Bank starts from an unusual position. Its 858,000 active customers, €10.2 billion of deposits and close connection to the S Group retail ecosystem give it everyday frequency that many smaller banks would struggle to manufacture. OmaSp would add more than 200,000 customer relationships, local and SME capabilities and a physical-service footprint, although there will inevitably be customer overlap and the two headline customer numbers therefore cannot simply be added.
If the combination succeeds operationally, I think S-Bank becomes less, rather than more, vulnerable to Revolut. It would have greater scale, a differentiated distribution ecosystem and broader banking capabilities. Its challenge is its 68 per cent 2025 cost-to-income ratio and the cost and complexity of integrating another bank. The strategic logic is strong; execution still matters.
OP and Nordea are also not where I would expect the most serious damage to appear first. OP has enormous domestic relationship density, mortgage and deposit scale, insurance, wealth products and cooperative economics. Nordea already operates with Nordic scale and a cost-to-income ratio in the mid-40s excluding regulatory fees, alongside substantial corporate banking and wealth-management businesses. They will lose some payments, deposits and younger customers to Revolut, but they have considerable capacity to respond.
The harder strategic question sits with the smaller institutions.
For the Savings Banks, locality and personal service remain genuine assets. Those assets are particularly valuable around mortgages, SMEs, agriculture and customers who want an adviser who knows them. Revolut cannot simply reproduce that through an app. The risk is that the cost of maintaining competitive digital services, regulatory capability and cyber-security continues rising while attractive transactional revenue gradually migrates elsewhere.
Aktia is somewhat better protected than size alone suggests. Its asset-management and life-insurance revenues mean it is not simply a smaller version of a universal mortgage bank. In the first half of 2026, net commission income increased while its comparable cost-to-income ratio stood at 61 per cent. Revolut’s increasingly broad wealth proposition is relevant, especially for younger affluent customers, but high-trust advisory wealth relationships are harder to commoditise than card payments or FX.
OmaSp’s standalone vulnerability increasingly becomes theoretical if the S-Bank transaction completes. Danske Bank is different again as it has less Finnish domestic ecosystem protection than OP but considerably greater Nordic scale than a local savings bank. Ålandsbanken occupies an even more differentiated wealth and relationship niche. The pattern matters more than a simple ranking. Small is dangerous when small also means undifferentiated. Small with a valuable niche can remain economically defensible.
So is Revolut a systemic threat? No, not on the evidence available today.
Is it a potentially serious competitive threat? Yes.
And for some banks, that distinction will offer little comfort.
What Finnish banks should do now
The wrong response would be to copy Revolut feature by feature.
A Finnish bank does not need another metal card because Revolut has one. It does not need to build its own cryptocurrency proposition, airline-points programme, travel marketplace and multi-currency engine in the hope of becoming a Finnish Revolut. Revolut’s advantage comes partly from operating one platform across tens of millions of customers and spreading product development across dozens of markets. Replicating its catalogue locally could actually worsen the scale disadvantage.
The first priority should instead be to measure relationship erosion properly. A bank can report low customer attrition while losing payment volume, deposit share, investment assets and customer attention. Executives should be looking at salary inflow, share of wallet, card usage, recurring outgoing transfers to fintechs, deposit migration and digital engagement at cohort level. A customer who has not closed their account can still be halfway out of the relationship.
Second, incumbents should defend the places where the Finnish banking relationship is genuinely difficult to replace. Mortgages remain important, but so do the connections between housing, insurance, wealth, family finances, SME relationships, electronic identification and advisory service. OP’s ecosystem, S-Bank’s retail connection, Aktia’s wealth capabilities and the Savings Banks’ local relationships are strategically more valuable than attempting to out-Revolut Revolut on international card features. The relevant question is whether those advantages are visible and valuable to customers, rather than merely present in the organisation.
Third, cost economics do matter. This is where smaller Finnish banks should be most concerned. They should not interpret the answer as another instruction to replace the core because a new competitor has arrived. The strategic response is broader with deliberate build, buy and consume decisions, more shared infrastructure where differentiation is negligible, automation of expensive operational processes, removal of product complexity, and progressive transformation focused on the businesses and customer relationships the bank actually intends to defend. Revolut’s scale makes commodity banking expensive to compete in with proprietary local machinery.
Finally, Finnish banks should resist the temptation to dismiss Revolut because most customers will not move their mortgage. That would be measuring the next competitive cycle with the assumptions of the previous one.
My likely-case forecast does not end with Revolut becoming Finland’s largest bank. It ends with something subtler. By the early 2030s, perhaps three quarters of a million Finns have a Revolut relationship. A significant minority use it as their everyday account. Several billion euros of balances sit on or through the platform. Revolut has established meaningful positions in cards, payments, savings, investments and unsecured credit, with some SME penetration and possibly selective mortgages. OP and Nordea remain much larger banks. S-Bank may have become a stronger national challenger through OmaSp. Local and specialist institutions still exist.
But the definition of a banking relationship has changed.
That is the risk I would take seriously. Revolut does not have to replace Finnish banks to alter their economics. It only has to persuade enough Finns that different parts of their financial lives can sit with different providers, then steadily capture the parts of the relationship that generate activity, data and revenue.
At 250,000-plus customers, that process has already started.
Key sources and methodology
My analysis draws primarily on Revolut’s Finnish branch announcement and 2025 financial disclosures, Revolut’s documented rollouts in Romania, Germany and Ireland, Bank of Finland deposit and lending statistics, FIN-FSA and European deposit-guarantee material on foreign EEA branches, and current financial disclosures from Nordea, S-Bank, OP Pohjola, OmaSp and Aktia. The scenario figures are my modelling assumptions rather than management guidance from Revolut or forecasts from the Finnish authorities; they are intended to test plausible economic outcomes against the disclosed >250,000-customer starting point and Finland’s €115.2 billion household-deposit base.
