How Banco Santander, S.A. Makes Money

Revenue derives from net interest income on mortgages, consumer loans, and SME lending, plus net fee income from payments, insurance distribution, and mutual fund sales. Revenue comes from fee-based asset management, private banking, and insurance premiums. Net fee income of EUR 13.0 billion contributed 21%, with gains on financial transactions and other operating income making up the remainder. However, the shift to electric vehicles is disrupting traditional auto finance: lower residual values and manufacturer direct-to-consumer sales models threaten the dealer-commission-based revenue model that generated EUR 260 million in provisions in 2024. Net fee income of EUR 13.0 billion increased 7% in constant euros, reflecting strong performance in wealth management, payments, and retail banking. Loan impairment charges were EUR 7.2 billion, or a cost of risk of 1.15%, within the 2024 target of approximately 1.2%. The UK motor finance scandal represents a specific conduct risk: in Q4 2024, the group recorded a EUR 260 million provision (net of tax and minority interests) for potential complaints related to motor finance dealer commissions, reflecting the Financial Conduct Authority's investigation into historical discretionary commission arrangements. The group's exposure to commercial real estate, particularly in Spain and the UK, represents a concentration risk: the CIB portfolio holds EUR 386 billion in real estate exposure across segments, and a 20% decline in European commercial property values could trigger material impairment charges. The Wealth Management & Insurance segment's RoTE of 78.7% in 2024 is exceptional and reflects a fee-based model that is less sensitive to interest rate fluctuations. The segment's EUR 498.3 billion in assets under management and administration, including EUR 88.8 billion in socially responsible investments, generates recurring fee income with minimal capital consumption.

The group's FY2025 half-year results accelerated this trajectory, with attributable profit reaching EUR 6.8 billion in H1 2025 — a 13% year-over-year increase and the fifth consecutive quarterly record. The Consumer Finance business holds EUR 100+ billion in assets and provides vehicle financing, personal loans, and credit cards through partnerships with retailers and auto dealers. The Corporate & Investment Banking (CIB) segment generated EUR 8.3 billion in revenue (13% of group total) with an efficiency ratio of 45.6% and RoTE of 18.0%. This segment manages EUR 498.3 billion in assets under management and administration, including EUR 88.8 billion in socially responsible investments. The Cards business issued and acquired credit and debit cards across all Santander markets. Net interest income of EUR 46.7 billion represented 75% of total income in FY2024, earned through the spread between interest on loans and investments and interest paid on deposits and borrowings. Santander's response — the Openbank platform and AI-driven customer service — requires sustained investment to close the experience gap. The US Banking Build-Out (US BBO) initiative, launched in 2023, aims to expand corporate banking relationships in the US, where Santander's market share is minimal. The group's FY2025 half-year results accelerated this trajectory: attributable profit of EUR 6.83 billion in H1 2025 (up 13% year-over-year, 18% in constant euros), RoTE of 16.7%, and CET1 of 13.0%. In H1 2025, the sharp fall in Argentine interest rates reduced net interest income in the Retail segment to flat year-over-year, masking 3% growth excluding Argentina. The Payments segment, while growing, remains a drag on group profitability: PagoNxt posted an attributable loss of EUR 304 million in H1 2024 (EUR 61 million excluding write-downs from discontinued merchant platforms in Germany and Superdigital in Latin America). The Cards business saw provisions rise 29% in H1 2025 due to strong portfolio growth and model changes in Brazil and Mexico. The ONE Santander program — which replaced 30 legacy core banking systems with a unified global platform — has delivered cost savings but requires ongoing investment in AI, cloud infrastructure, and cybersecurity. The Poland disposal, announced in 2024 and progressing through 2025, eliminates a growth market but allows capital reallocation to higher-return regions. This diversification reduces dependence on any single economy and allows capital reallocation toward regions with higher growth. Santander Consumer Finance operates in 17 European countries with assets exceeding EUR 100 billion, holding partnerships with major auto manufacturers and dealer networks. The EUR 10 billion shareholder distribution plan for 2025-2026, including exceptional share buybacks, signals confidence in capital generation but also reflects limited high-return investment opportunities. Banco Santander's growth strategy is built around four axes: expanding retail banking profitability in its nine core markets, scaling its digital and payments platforms, growing fee-based businesses that are less sensitive to interest rate cycles, and maintaining disciplined capital allocation that supports a double-digit return on tangible equity. In its largest markets, Santander is pursuing profitable growth rather than volume growth. In Spain, the strategy centres on cross-selling investment and insurance products to existing retail customers, reducing reliance on spread income by growing fee revenue from asset management and transactional banking. In Brazil, which generated the group's highest absolute profit contribution in FY2024, Santander is deepening digital customer engagement through its Superdigital platform and expanding its auto-financing business through Santander Financiamentos. In the United States, the group is focused on its Santander Consumer USA auto lending franchise and the selective build-out of its corporate and investment banking business for Latin American multinationals. On the digital side, Santander has invested heavily in Openbank, its fully digital bank operating across Spain, Germany, the Netherlands, Portugal, and the US, targeting price-sensitive customers who want competitive deposit rates without branch infrastructure. The capital strategy is explicit: Santander targets a fully loaded CET1 ratio above 12%, returns surplus capital through a combination of cash dividends and share buybacks, and aims to grow tangible book value per share consistently through the cycle. The bank's initial capitalization came from 72 local businessmen, and its first decades were focused on the Cantabrian coast and maritime commerce. Emilio Botín y López was appointed managing director in 1934, and in 1950 he became chairman, promoting aggressive growth throughout Spain. The 1988 acquisition of a stake in Portuguese Banco de Comércio e Indústria and a strategic partnership with The Royal Bank of Scotland marked the first European expansion beyond Spain. The 1989 launch of the 'Supercuenta Santander' — a high-interest current account — revolutionized Spanish retail banking and opened the traditionally closed financial system to competition. That same year, Santander acquired Grupo Serfín in Mexico and Banco Santiago in Chile. The 2007 consortium bid for ABN AMRO — alongside Royal Bank of Scotland and Fortis — was the boldest move: Santander acquired Banco Real in Brazil and Banca Antonveneta in Italy, though the deal contributed to RBS's near-collapse. The 2011 acquisition of SEB's retail banking business in Germany and Bank Zachodni WBK in Poland expanded the European footprint. Under her leadership, the bank has focused on digital transformation, sustainability, and operational efficiency.
