Banks Must Act Now to Thrive in an Era Where AI Agents Control Customer Decisions

Retail banks have long structured their strategies around quarterly earnings, annual budgets, and short-term goals. But a forward-looking exercise from Deloitte challenges that mindset — asking leaders to imagine the industry 25 years from now and consider what changes they should start making today.

Deloitte’s “2050: Banking Beyond” initiative explores how AI agents, data portability, embedded finance, and evolving customer expectations could fundamentally reshape retail banking. Rather than relying on precise forecasts, the project pushes executives to stress-test their current assumptions against multiple plausible futures.

Why a 25-Year View Matters Right Now

Nick Cowell, who leads Deloitte’s U.S. retail banking strategy practice, argues that the value of long-range planning lies not in predicting the future accurately but in identifying investments that remain valuable across multiple scenarios. Speaking on a recent Banking Transformed podcast, Cowell urged banks to focus on strengthening capabilities that can weather any version of the future — including transforming proprietary customer data into actionable insights, leveraging AI as a growth engine, modernizing core infrastructure and APIs, and redefining the role of human interaction.

Five Strategic Priorities for Banks Preparing for 2050

  • Challenge short-term assumptions with long-range scenarios to uncover investments that pay off across different time horizons.
  • Convert proprietary customer data into a competitive asset by translating transactional signals into timely, context-aware engagement.
  • Build AI-readiness as a foundational capability through robust data infrastructure, APIs, analytics, and transparency practices.
  • Reposition human service around interaction value rather than simply the cost of delivery.
  • Develop a flexible distribution model that blends digital self-service, technology-driven engagement, and human touchpoints based on customer context.

When AI Agents Sit Between You and Your Customer

One scenario in the Deloitte series has provoked strong reactions among banking leaders: the possibility that consumers will eventually delegate financial decisions to AI agents. In this model, the bank no longer competes directly for a customer’s attention — it competes for the attention of an algorithm evaluating options on the customer’s behalf.

An AI agent assessing financial products would weigh factors like price, terms, speed, and outcomes rather than relying on brand familiarity or relationship history. That shift threatens what banks have long considered a core asset — the direct customer relationship.

“If that relationship is depreciated or demised,” Cowell explains, “and an agent begins choosing on the customer’s behalf, loyalty and brand equity become less influential.” A customer might remain at a bank for years, yet the agent could move money or shift products the moment another institution offers a better result.

While skeptics rightly point out that consumers would need significant trust and that strong guardrails would be essential, Cowell argues that skepticism is precisely why the scenario deserves attention today. The real strategic question is not whether every customer will hand control to an AI agent — it is whether banks are ready for a world where at least some financial decision-making moves outside the traditional bank-customer relationship.

Turning Transactional Data Into Meaningful Insights

If AI agents begin mediating more financial decisions, banks will need compelling reasons to remain relevant. Cowell believes proprietary customer data represents one of their most powerful potential advantages.

“Your bank knows a lot about you, yet tells you very little,” he observes. Banks sit on years of transactional and behavioral data but often fail to convert those signals into useful engagement. For example, a customer who repeatedly transfers funds to another institution is sending a clear signal about the state of that relationship — a signal that could prompt a proactive conversation, a tailored offer, or another intervention designed to strengthen the bond.

Cowell recommends that banks invest in cleaning up their data infrastructure, enhancing the analytics layer around it, and identifying the specific behavioral triggers that should spark action. The objective is to convert raw data into contextual intelligence rather than simply accumulating more of it.

As AI becomes embedded in financial decision-making, data capabilities could grow even more valuable. A bank processing billions of transactions with deep insight into an individual customer’s history may offer recommendations that a general-purpose AI cannot easily match. Cowell even envisions proprietary data and contextual insights becoming a standalone revenue stream through subscription or usage-based models.

The Growing Role of Human Interaction in Digital Banking

As digital self-service continues to improve, Cowell sees a distinct and important role for human interaction — but only when the context makes it genuinely valuable.

That might look like a banker reaching out after a fraud incident, during a major life milestone, or when data patterns suggest a customer is considering a significant financial decision. Cowell offers the example of recognizing that a customer recently married and determining that a conversation about purchasing a home would be far more relevant than another generic digital notification.

This requires banks to rethink who gets access to human support and why. Cowell warns that relying primarily on cost-to-serve metrics leads to poor decisions. Instead, institutions should weigh the value of the interaction against the potential value of the broader relationship.

As products become easier to compare and increasingly commoditized, the quality and context of the relationship could become the most meaningful differentiator. Cowell expects that banks thoughtfully combining digital and physical channels — along with self-service and advisor-led interaction — will hold a significant competitive edge.

Laying the Groundwork for Multiple Possible Futures

The practical challenge for executives is carving out room for long-term investment while still delivering near-term financial results. Cowell’s recommendation: ring-fence a dedicated pool of capital and talent that operates on a different timeline and measures success differently.

That investment doesn’t need to begin with speculative technology. Several foundational capabilities deliver value on both short-term and long-term horizons:

  • Modern core banking architecture that supports agility and scalability.
  • Clean, real-time APIs that are easily exposed and integrated.
  • Rich data and advanced analytics that drive contextual decision-making.
  • Organization-wide AI fluency that accelerates adoption and innovation.
  • A product and service innovation culture that encourages experimentation.

Flexibility is critical because Cowell does not expect industry success to be determined solely by scale. Larger institutions may have more discretionary capital, but size does not guarantee speed in changing business models, culture, or customer experience. Smaller banks and neobanks have already proven they can identify friction points and compete effectively by borrowing experience-design principles from other industries.

The bottom line: The banks best positioned to remain relevant through 2050 will likely be those that protect ownership of the customer relationship while combining their balance sheets, data, AI capabilities, and distribution networks to create value at the moments customers need it most.
