Santander stock trades steady as Q1 2026 profit rises on higher net interest income

Santander stock reflects a stronger start to 2026 after the Spanish banking group reported higher Q1 2026 profit on rising net interest income and continued capital discipline.

Banco Santander S.A. (ISIN ES0113900J37) began 2026 with improved profitability, as Santander stock tracks a first quarter marked by higher net interest income and resilient capital ratios, according to the bank's Q1 2026 results published on 30 April 2026.

Q1 2026 profit up year on year

According to the Q1 2026 financial report released by Banco Santander, the group generated an attributable profit of EUR 3.00 billion in Q1 2026, compared with EUR 2.90 billion in Q1 2025. This represents an increase of about 3.4% year on year and continues the bank's gradual earnings expansion despite a more normalized interest-rate backdrop in key markets.

Net interest income, a core driver of bank earnings, reached EUR 11.80 billion in Q1 2026 versus EUR 11.10 billion in the same quarter a year earlier, rising by roughly 6.3% as reported in the same Q1 2026 release from Banco Santander. Management highlighted that higher volumes in retail and commercial banking, together with disciplined pricing in core geographies such as Spain, Brazil, and the United States, underpinned the improvement in net interest income.

Fee income and other revenues helped support the top line as well. The Q1 2026 update from Banco Santander indicates that total income, including net interest income and fee-based revenue, surpassed EUR 15 billion for the quarter, providing a revenue base that allowed the group to absorb cost inflation and maintain profitability.

Capital and asset quality metrics support valuation

The bank's Q1 2026 report shows that the fully loaded Common Equity Tier 1 (CET1) capital ratio stood at 12.6% at the end of Q1 2026, compared with 12.4% at the end of Q1 2025, indicating a 0.2 percentage-point improvement year on year. According to Banco Santander's investor information, this capital position remains within the bank's targeted management range and provides a buffer against macroeconomic uncertainty.

Asset quality also remained stable in the quarter. The non-performing loan (NPL) ratio was reported at 3.0% at the end of Q1 2026, broadly in line with the 3.1% level recorded a year earlier according to the same Banco Santander disclosure. The cost of risk, which measures loan-loss provisions relative to total loans, remained contained and consistent with the bank's medium-term guidance range as cited in its Q1 2026 presentation, helping to limit earnings volatility.

For equity investors, these capital and asset-quality figures are an important backdrop for Santander stock. A CET1 ratio of 12.6% and an NPL ratio around 3.0% suggest that, as of the end of Q1 2026, the group is balancing growth with risk control. This can influence how the market assesses the sustainability of the bank's dividend capacity and the potential for future capital distributions, particularly as European regulators have normalized their stance on bank payouts following the post-pandemic period.

Retail banking and digital services

Banco Santander generates a substantial share of its earnings from retail and commercial banking in Europe and the Americas, with products ranging from current accounts and mortgages to consumer finance and small-business lending. According to the group's overview for shareholders and investors, the bank serves more than 160 million customers across its core markets, with a significant portion using digital channels for everyday banking services. For investors looking at Santander stock, the scale of this customer base is central to assessing long-term earnings power.

Santander stock and market context

In addition to earnings and capital, valuation indicators such as market capitalization help frame the position of Santander stock in the broader European banking sector. Based on recent data presented in the shareholder and investor materials from Banco Santander, the group has a market capitalization in the tens of billions of euros, placing it among the larger listed banks in the euro area. This scale is relevant when comparing liquidity and index representation with other major European financial institutions.
