Banks around the world are facing growing pressure to adapt as customers rapidly adopt artificial intelligence for managing personal finances, according to a new report by McKinsey & Company. The report says generative AI and “agentic AI” are spreading far faster than earlier technological shifts such as mobile banking or big data. While older technologies often took five to ten years to evolve into mainstream financial tools, agentic AI is expected to reach advanced adoption within just two to three years.
Consumers are already using AI tools for increasingly sophisticated banking activities, including comparing financial products, identifying higher-yield savings accounts, refinancing loans, reducing credit card debt, and even receiving investment guidance. McKinsey noted that some AI systems are beginning to outperform professional stock pickers in specific areas, signaling a major shift in how people seek financial advice. Surveys cited in the report show that trust in AI for financial decision-making is also rising rapidly across multiple age groups.
The growing use of AI threatens to weaken the direct relationship between banks and customers. McKinsey warns that future AI assistants may autonomously scan financial markets, compare offers, and execute transactions without users ever opening a banking app or visiting a branch. Analysts describe this as a potential “disintermediation” of banks, where AI agents become the primary interface for customer financial decisions instead of traditional banking platforms.
To remain competitive, experts say banks must evolve into AI-first institutions by redesigning customer experiences, integrating AI deeply into operations, and building more personalized, data-driven services. Reports from McKinsey emphasize that AI adoption is no longer simply about automation or cost reduction — it is becoming central to customer engagement, product delivery, and long-term survival in the banking industry. Institutions that fail to adapt quickly risk losing relevance as AI increasingly reshapes how consumers interact with financial services.
