Banking has left the quiet-pilot phase behind. In June, Banco Santander announced it is extending access to its artificial intelligence tools to its entire workforce, 185,000 people worldwide, up from the roughly 40,000 already using them. The bank reports more than 280 process automation agents in production, returns of 35 million euros in the first quarter of 2026 alone, and a target of more than 1 billion euros in business value between 2026 and 2028.
It is not an isolated case. At Bank of America, employees make more than 400,000 daily prompts to internal AI tools; the bank has more than 300 approved use cases and 114 generative AI applications already live. HSBC has signed a multi-year alliance with Google to develop more than 200 use cases within two years, with wealth management and financial crime detection among the priorities. And a recent KPMG survey puts at 51% the share of banks already piloting AI agents: Morgan Stanley is preparing assistants for its advisers this summer, Goldman Sachs is working with Anthropic, and Citi is developing virtual wealth management capabilities.
What does the customer gain from all this? Three things, if it is done well. Speed: processes such as loan pre-approval move from days to minutes. Security: fraud detection systems improve measurably when they incorporate these models. And availability: service stops having opening hours.
And what should you watch? Three things as well. First: when a decision is made by an automated system (a credit limit, a pre-approval), the customer retains rights; in Europe, data protection law supports human review of automated decisions with significant effects, and in the United States credit regulations require lenders to explain denials. Those rights are worth exercising. Second: know who you are talking to; in the European Union, AI assistants must also identify themselves as such from 2 August 2026. Third: a bank's assistant works for the bank. It can be useful for transactions and questions, but it replaces neither your own financial education nor independent advice.
The underlying paradox deserves a line of its own: the more banking automates, the more valuable the customer's financial literacy becomes. Understanding what you are being offered, which of your data feeds the decision and what alternatives exist is the difference between riding this wave and being carried by it.
