How Does Santander Make Money?
Santander generates 75% of its revenue from net interest income — the spread between interest earned on loans and investments and interest paid on deposits and borrowings — yielding EUR 46.7 billion in FY2024. The remaining 25% comes from net fee income (EUR 13.0 billion), gains on financial transactions (EUR 1.4 billion), and other operating income.
The Retail & Commercial Banking segment is the largest contributor, generating EUR 32.5 billion (52% of group revenue) with an efficiency ratio of 39.7% and return on tangible equity of 18.8%. The Digital Consumer Bank (including Santander Consumer Finance and Openbank) added EUR 12.9 billion (20%), specializing in auto finance and digital banking. Corporate & Investment Banking contributed EUR 8.3 billion (13%), Wealth Management & Insurance EUR 3.7 billion (6%), and Payments EUR 5.5 billion (9%).
The group's net interest margin is supported by geographic diversification: Europe contributes 52% of profit, North America 22%, and South America 28%. The efficiency ratio of 41.8% is among the best in global banking, reflecting the ONE Santander transformation. Operating expenses totaled EUR 26.0 billion, yielding a cost-to-income ratio that improved 2.3 percentage points from 2023. Loan impairment charges were EUR 7.2 billion, or a cost of risk of 1.15%.
Who Founded Santander and When?
Banco Santander was founded on 15 May 1857 by royal decree of Queen Isabella II of Spain, with 72 local businessmen in the port city of Santander providing initial capitalization to finance maritime trade with Latin America. The bank's modern expansion was driven by four generations of the Botín family: Emilio Botín y López (chairman 1950-1986), Emilio Botín Sanz de Sautuola (chairman 1986-2014), and Ana Botín (executive chair from 2014).
The bank expanded from a regional Spanish institution to a global powerhouse through acquisitions in Latin America (Banespa 2000, Grupo Serfín 2000, Banco Santiago 2000), Europe (Abbey National 2004, SEB Germany 2011, Bank Zachodni WBK 2011), and the US (Sovereign Bank 2008). The 1999 merger with Banco Central Hispano created Spain's largest bank and the platform for global expansion.
What Is Santander's Competitive Advantage?
Santander's single unreplicable moat is its dual-scale advantage: global technology platforms that reduce unit costs, combined with deep local market knowledge and regulatory relationships in 10 core countries. The ONE Santander transformation has replaced 30 legacy core banking systems with a single global platform, enabling the bank to develop the best technology once and operate it centrally.
The Retail segment's efficiency ratio of 39.7% in 2024 — improving to 39.4% in H1 2025 — demonstrates this operational leverage: revenue grew 11% while costs declined 3.4 percentage points as a share of income. The group's geographic diversification across Europe, North America, and South America reduces dependence on any single economy, and its Latin American franchise provides access to higher-growth markets that European competitors cannot replicate without decades of investment.
How Has Santander's Revenue Grown Over Time?
Santander's revenue trajectory reflects its transformation from a regional Spanish bank to a global diversified group. Underlying total income was EUR 57.6 billion in FY2023, EUR 62.2 billion in FY2024 (up 10% in constant euros), and on track for approximately EUR 62 billion in FY2025. Net interest income grew from EUR 43.3 billion in 2023 to EUR 46.7 billion in 2024.
The group's revenue peaked at EUR 48 billion in 2008 before the financial crisis, collapsed during the European sovereign debt crisis, and recovered through the 2015-2019 period. The 2022-2024 interest rate hiking cycle reversed years of margin compression, with the efficiency ratio improving from 48% in 2019 to 41.8% in 2024. The 2025 H1 results show continued momentum with EUR 33.5 billion in total income and EUR 6.83 billion in attributable profit.
Santander Business Model Explained
Santander operates a diversified banking model funded by customer deposits and deployed into loans, investments, and fee-based services. Customer deposits of EUR 1.06 trillion fund net loans to customers of EUR 1.05 trillion, with a loan-to-deposit ratio of 100%. The bank's structural hedge and active liability management protect net interest income from rate fluctuations.
The group's capital generation pre-distributions supports a fully-loaded CET1 ratio of 12.8% while distributing approximately 50% of attributable profit to shareholders through dividends and buybacks. The EUR 10 billion shareholder distribution program for 2025-2026 reflects confidence in capital generation. The bank's funding model relies on stable retail deposits, with wholesale funding providing liquidity buffers.
Santander Key Acquisitions
The 2000 acquisition of Banespa for $3.5 billion established Santander as a major force in Brazil. The 2004 Abbey National acquisition for $12.2 billion created Santander UK. The 2008 full acquisition of Sovereign Bank established the US retail presence. The 2007 ABN AMRO consortium bid gave Santander Banco Real in Brazil and Banca Antonveneta in Italy.
Recent strategic moves include the 2024 announcement to dispose of Santander Bank Polska and the 2025 sale of the remaining 30.5% stake in CACEIS. The 2025 merger of Openbank with Santander Consumer Finance creates a digital-consumer finance hybrid. These moves reflect a portfolio optimization strategy focused on higher-return markets.
What Are the Biggest Risks Facing Santander?
The most immediate risk is the UK motor finance scandal, where a EUR 260 million provision in Q4 2024 reflects the FCA investigation into historical dealer commission arrangements. This could escalate if broad redress is mandated. Regulatory pressure in Europe — including Spain's temporary levy and Basel 3.1 implementation — adds EUR 500+ million in annual costs.
Latin American currency volatility erodes reported earnings: approximately 45% of profit comes from Brazil, Mexico, Chile, and Argentina, where depreciation against the euro can reduce translated earnings by 5-10% annually. Digital challengers like Nubank in Brazil and Monzo in the UK are capturing younger demographics with lower-cost models. The group's 2025 targets require defending market share while maintaining the 41.8% efficiency ratio.
Bottom Line
Santander is growing, with total income increasing 10% to EUR 62.2 billion in FY2024 and attributable profit rising 14% to EUR 12.6 billion, with return on tangible equity of 16.3%. The bank's ONE Santander transformation has delivered an industry-leading efficiency ratio of 41.8%, and the 2025 H1 results show continued momentum with EUR 6.83 billion in profit. The EUR 10 billion shareholder distribution program reflects confidence, but the long-term test is whether the bank can sustain 16%+ RoTE when interest rates normalize, Latin American currencies depreciate, and digital challengers capture the next generation of customers.
