Santander chair challenges UK bank taxes

Santander executive chair Ana Botín has criticised the UK’s banking tax regime, intensifying debate over whether sector-specific taxes are weakening the country’s competitiveness as a financial centre.

Botín argued that the current tax treatment of banks in the UK is economically unjustified, with lenders being singled out despite their role in financing businesses, households, investment, and growth.

UK banks pay corporation tax, a bank levy on balance sheets, and a surcharge on profits. The framework dates back to the post-financial crisis period, when policymakers sought to recoup public costs and reduce systemic risk after the rescue of parts of the banking sector.

The political and economic context has since shifted. Banks are now being asked to support growth, finance infrastructure, fund net-zero transition, expand SME lending, improve fraud protection, and invest in digital resilience. At the same time, the sector remains a tempting source of revenue for governments managing strained public finances.

The comments follow Santander’s £2.65bn acquisition of TSB, which expanded the group’s UK customer base and reinforced its position as one of the country’s largest retail banking groups.

At Banco Santander’s annual general meeting earlier this year, Botín said the group had started 2026 strongly, maintaining growth in customers and revenue while improving efficiency. She also confirmed the group’s 2026 targets, including mid-single digit revenue growth, lower costs in constant euros, stable cost of risk, and profit growth compared with €14.1bn in 2025.

Santander has set 2026–2028 targets including profit of more than €20bn in 2028, return on tangible equity above 20%, and more than 210m customers. The bank has said artificial intelligence is already improving customer experience, risk management, fraud prevention, productivity, and access to credit, with expected business value of more than €1bn by 2028.

The UK tax debate sits inside a broader question about where international banks allocate capital. Large lenders compare regulatory cost, tax treatment, growth prospects, political stability, and returns across markets. A country can remain attractive for customers and talent while still losing marginal investment if its fiscal and regulatory environment is seen as less competitive.

Bank taxation remains politically sensitive. The sector benefited from extraordinary public support during the financial crisis, and public expectations of contribution remain high. Higher interest rates have also improved net interest income for many lenders, leading to periodic calls for additional taxation when household borrowing costs rise.

The industry’s counterargument is that banks are not windfall businesses in the same way as commodity producers. They operate under capital rules, liquidity requirements, conduct regulation, consumer duties, anti-fraud obligations, technology investment demands, and competition from fintechs and non-bank lenders. Additional tax costs can affect retained capital, lending appetite, pricing, shareholder returns, and investment in systems.

Financial services are central to several government objectives. Ministers want more business investment, deeper capital markets, stronger SME finance, more pension capital deployed into productive assets, and faster growth in technology and infrastructure. Banks are one part of that ecosystem, but they also face political pressure on branch access, fraud reimbursement, savings rates, mortgage affordability, and lending standards.

International competition adds another layer. The UK is trying to maintain the City’s global standing while rebuilding parts of its economic relationship with Europe and competing with the United States, Switzerland, Singapore, and Gulf financial centres. Tax policy is only one factor, but it contributes to the signal sent to boards deciding where to expand, hire, and allocate capital.

The government has to balance that competitiveness case against fiscal pressure. Public finances remain tight, and any move to reduce bank-specific taxes would require either lower revenue, replacement measures, or a political argument that stronger sector investment would support growth over time. That is a difficult case to make when households and small businesses are still under cost pressure.

The strategic risk is that tax concerns merge with wider frustration over regulation, political scrutiny, and operating costs. If banks believe the UK is becoming less predictable, investment decisions may become more conservative. If policymakers believe the sector is resisting reasonable contribution, pressure for further levies may increase.

The discussion is likely to continue as the government develops its growth and financial services agenda. Botín’s intervention carries weight because Santander is both a major UK retail bank and a global group with choices about where it deploys capital. The central policy question is no longer whether banks should contribute more than standard corporation tax. It is whether the current balance supports the investment, lending, and competitiveness the UK now says it wants.
