Santander, BBVA, CaixaBank asset sizes

Banco Santander remained Spain’s biggest bank by balance sheet in 2025, ending the year with about €1.88 trillion in total assets. (santander.com) (companiesmarketcap.com) BBVA ended 2025 with €859.6 billion in total assets, according to the bank’s published financial data. CaixaBank reported €731.9 billion in total assets for the same period. (bbva.com) (caixabank.com) That means Santander’s balance sheet was more than twice BBVA’s and well over €1 trillion larger than CaixaBank’s at year-end 2025. The gap helps explain why Santander is usually discussed as a global bank first and a Spain-only story second. (bbva.com) (caixabank.com) (companiesmarketcap.com) The comparison also shows why social-media summaries can mislead if they mix “assets,” “customer funds,” and other banking measures. Santander’s 2025 materials highlight loans, deposits and assets under management in different places, and those are not interchangeable with total assets on the balance sheet. (santanderannualreport.com 1) (santanderannualreport.com 2) BBVA’s own numbers underline that point. It reported €726.9 billion in total customer funds and €502.5 billion in customer deposits, both below its €859.6 billion total-assets figure. (bbva.com) CaixaBank’s 2025 report shows the same distinction. It listed €384.3 billion in gross loans to customers and €731.9 billion in total assets, which are separate lines serving different analytical purposes. (caixabank.com) Santander’s year-end balance sheet was also affected by the agreed sale of roughly 49% of Santander Bank Polska to Erste Group. The bank said assets tied to that disposal were classified as held for sale from the second quarter of 2025 under International Financial Reporting Standards 5. (santander.com) Spain’s sovereign backdrop looked less strained than the 117%-of-gross-domestic-product figure cited in some older commentary. Banco de España said general government debt stood at 103.5% of gross domestic product in the first quarter of 2025 and later year-end reporting put 2025 at 100.8%. (bde.es) (thecorner.eu) For investors, the clean takeaway is narrower than the online debate: Santander is still in a different size class, while BBVA and CaixaBank are large but materially smaller by assets. The exact ranking is straightforward; the harder part is making sure everyone is talking about the same banking metric. (santander.com) (bbva.com) (caixabank.com)
