Revolut added 12 million customers in 2024 alone, bringing its total to 50 million across 38 markets. Nubank crossed 100 million accounts in Latin America. Monzo reached 10 million in the UK. These are not projected figures or targets. They are reported numbers from fintech-powered banks that did not exist 12 years ago. The neobanking market that supports them reached $210.16 billion in 2025, according to Fortune Business Insights, growing at a 49.30% compound annual rate toward a projected $7.66 trillion by 2034.
The Cost Structure That Enables Rapid Growth
The expansion of fintech-powered banks starts with a simple arithmetic advantage. A traditional bank with 500 branches spends between $2 million and $5 million per branch annually on rent, staff, security, and maintenance. A network of 500 branches therefore costs $1 billion to $2.5 billion per year before a single loan is underwritten or a single deposit is gathered.
Fintech-powered banks replace that branch network with a mobile application and a cloud-hosted core banking platform. Their largest cost categories are technology infrastructure (cloud computing, API services, cybersecurity) and customer acquisition (digital marketing, referral incentives). For a neobank at scale, total operating costs typically run between 30% and 45% of revenue. Traditional banks operate at 55% to 70%.
That 20-to-30-percentage-point gap in cost-to-income ratios creates two strategic options. Fintech-powered banks can either offer lower prices (no monthly fees, higher savings rates, lower FX margins) to acquire customers faster, or they can retain the savings as margin. Most have chosen the first option during their growth phase, sacrificing short-term profitability for market share.
Geographic Expansion Patterns
Fintech-powered banks are expanding along three geographic corridors, each shaped by different regulatory and market conditions.
The first corridor runs through Europe. The EU’s single banking passport allows a bank licenced in one member state to operate across all 27. Revolut, licenced in Lithuania, uses this mechanism to serve customers from Portugal to Finland without obtaining separate licences in each country. Europe accounts for 37.20% of the global neobanking market, per Fortune Business Insights, the largest regional share. The continent’s high smartphone penetration, standardised payment infrastructure (SEPA), and supportive open banking regulation make it the most efficient geography for fintech bank expansion.
The second corridor covers Latin America and Africa, where fintech-powered banks are reaching customers that traditional banks never served. Brazil’s Pix instant payment system, launched in 2020, processed 42 billion transactions in 2024 and created the infrastructure on which neobanks could build lending, insurance, and investment products. In Nigeria, Opay and Kuda are providing basic banking services to populations where branch banking coverage is thin. In these markets, fintech-powered banks are not competing with traditional banks so much as creating the banking system for the first time.
The third corridor is Southeast Asia, where digital bank licences issued in Singapore, Malaysia, the Philippines, and Indonesia between 2022 and 2024 have opened the market to new entrants. Grab, Sea Group, and other technology companies have obtained banking licences and are layering financial services onto existing super-app ecosystems with hundreds of millions of users.
The Banking-as-a-Service Engine
Behind many fintech-powered banks is a banking-as-a-service (BaaS) provider that supplies the regulatory infrastructure. The global BaaS market reached $18.6 billion in 2024, according to Global Market Insights, and is projected to reach $73.7 billion by 2034 at a 15.1% CAGR. Platform-based models account for 69% of the market, and cloud deployment holds a 67% share.
The BaaS model works because banking licences are expensive, slow to obtain, and jurisdictionally limited. A fintech company that wants to offer deposit accounts in the United States needs a banking charter or a partnership with a chartered bank. Companies like Column, Lead Bank, and Blue Ridge Bank provide that charter as a service, handling regulatory compliance while the fintech partner handles the customer experience.
This arrangement has allowed hundreds of fintech-powered products to reach the market without each one obtaining its own licence. It has also concentrated systemic risk in a small number of partner banks, a fact regulators are now addressing.
Where the Growth Faces Friction
Three forces are slowing, though not reversing, the expansion of fintech-powered banks.
Regulatory tightening is the first. The Synapse collapse in 2024 exposed weaknesses in the BaaS model when the middleware provider failed and customers could not access their deposits. US regulators responded with increased scrutiny of bank-fintech partnerships. The FDIC issued guidance requiring sponsor banks to maintain direct oversight of all fintech partner activities, not just periodic audits. In Europe, DORA (Digital Operational Resilience Act) effective January 2025 requires all financial institutions, including neobanks, to prove their technology supply chains can withstand operational disruptions.
Funding constraints are the second. Venture capital investment in fintech fell from its 2021 peak, and neobanks that had not reached profitability found it harder to raise subsequent rounds. The market is no longer funding growth-at-all-costs strategies. Investors want a path to positive unit economics before writing checks.
The third is competition from incumbents. Traditional banks are investing heavily in technology modernisation. JPMorgan Chase spent $17.1 billion on technology in 2024. Bank of America reported 47 million active digital users. These institutions have the capital, the customer base, and the regulatory standing to compete on technology once they complete their modernisation programmes.
The Cross-Border Opportunity
One area where fintech-powered banks retain a clear and widening advantage is cross-border payments. The global cross-border payments market reached $371.59 billion in 2025, according to Fortune Business Insights, growing toward $727.74 billion by 2034 at a 7.90% CAGR.
Traditional banks charge 3% to 5% for international wire transfers, with additional intermediary bank fees and multi-day settlement times. Fintech-powered alternatives process the same transfers at 0.3% to 1% with near-instant settlement. Wise processed over $118 billion in cross-border volume in its 2024 fiscal year. That volume represents customers who have permanently moved their international payments away from traditional banks.
API infrastructure makes this possible at scale. Over 2 billion API calls flow through the global banking system daily, processing $676 billion in transaction value, according to Coinlaw. Fintech-powered banks use this infrastructure to connect directly to local payment networks in multiple countries, bypassing the correspondent banking chain that traditional international transfers rely on.
Fintech-powered banks are expanding rapidly because their economics are better, their technology is faster, and their addressable market keeps growing. The question is no longer whether they will take meaningful share from traditional banking. It is how quickly regulation and capital markets will force them to prove they can do it profitably.
