Agentic AI in Banking: Five Reasons to use it and five reasons not to let it run alone

For banks, the real promise of agentic AI lies in resolving complex customer needs faster, without sacrificing control, accountability or trust.

Banking journeys change all the time. How things happen now is a far cry from how they happened one or two years ago, never mind the dark days of branch visits and queueing.

What hasn’t changed, though, is that those banking journeys are still repetitive, data-heavy, and often spread across multiple systems, some of which are older than the employees using them.

Agentic AI has promise, and that promise could untangle things like onboarding a customer, investigating a disputed transaction, collecting compliance documents, or starting account applications.

But these are the same journeys where a wrong action can move money, expose personal data, deny access to a service or create a regulatory problem.

The question is, how much authority should a bank give AI? 

What makes AI agentic?

A chatbot can answer a question, collect information and follow a predefined workflow. Many good banking journeys can and should be solved that way. 

An AI agent is different because it doesn’t answer; it acts. It can decide which steps are needed, select approved tools, act on what it discovers, adapt when the situation changes and continue until it reaches a defined outcome or a boundary that requires human judgement.

Take an SME account application for example. A chatbot can provide a document list and collect uploads. A proper agentic system could identify the type of legal entity, build a case-specific plan, inspect the submitted documents, query approved identity and company-information services, spot inconsistencies, ask a tailored follow-up question and prepare the case for review. The final decision can still belong to a human who’s authorised to make the call.

The market is not on autopilot (yet)

The latest official local benchmark, published by the FSCA and PA in November 2025 using survey data collected in late 2024, found that 52% of responding banking institutions were already using AI in some way, shape or form. 

Globally, adoption has moved beyond conventional AI. The University of Cambridge’s 2026 Global AI in Financial Services Report found that 81% of surveyed financial services firms were adopting AI at some level, while 52% were already piloting or deploying agentic AI. However, only 23% had progressed to the scaling or transformation stage. Among traditional financial institutions specifically, agentic AI adoption stood at 45%, compared with 57% among FinTechs. The same report highlighted privacy, bias, discrimination, explainability, governance, reputational harm and systemic vulnerabilities. In other words, adoption is growing at the same time as the consequences are becoming harder to ignore.

Five reasons why banks should use agentic AI

 

  1. It can manage an outcome across systems

A chatbot can tell a customer how to replace a lost card or guide them through a predefined sequence of questions. An AI agent can go further. Within its approved permissions (this is an important point), it could verify the customer, retrieve recent transactions, identify which payments need to be queried, request confirmation before blocking the card, initiate the replacement order, for example.

  1. It can adapt inside the case

Banking cases are usually more complicated than they appear to be. Maybe there’s a document that’s missing or the ‘customer’ is a trust rather than an individual. An agent can adjust its next step within policy instead of sending every deviation into the same manual queue.

  1. It can do prep work for human agents

An agent can gather records, compare evidence, retrieve the relevant policy, flag discrepancies and produce a traceable case summary. Fraud, compliance and credit teams would spend less time assembling the file and more time applying judgement.

  1. It keeps work moving after the chat ends

An agent can monitor an approved process, check whether a requested document has arrived, update the case and alert the right person when a condition is met. 

  1. It can give skilled teams their judgement time back

The point is to remove the work that keeps skilled employees away from exceptional cases, relationships and decision-making. Agentic AI can give specialists a more complete case and customers a faster route to someone who can help.

"

The objective is not autonomy for its own sake. It is to reduce avoidable handling, shorten time to resolution and return skilled employees to the work that genuinely requires experience, accountability and judgement.”

Five reasons not to let it run alone

  1. A wrong answer can become a wrong action

A chatbot that produces a poor answer creates a smaller service problem. An agent with system access and autonomy can create a much bigger operational one. It may update the wrong record, take an action from incomplete evidence or confidently pursue the wrong goal. The greater the authority, the greater the need for approval, testing and reversibility.

  1. Every tool becomes another door

Agents become useful by connecting to data and tools. Prompt injection, compromised documents, stolen credentials or excessive permissions can manipulate the agent or expose information. An agent that only needs to read a document should not have permission to delete it, alter it or release data elsewhere.

  1. Accountability becomes blurry very quickly

A multi-step agent may use several models, data sources and tools before reaching an outcome. When something goes wrong, the bank still needs to show what happened, which information was used, why the action was allowed and who owned the decision. 

  1. Bias can compound across a journey

Bias can enter through requested documents, case priority, customer language and chosen escalations, not just a final credit score. A sequence of individually plausible steps can still produce an unfair outcome.

  1. The agent may be yours, but the dependency may not be

Banks may rely on external models, cloud platforms, data providers and specialist tools. An outage, model change or shared vulnerability can affect important services. 

Why human-led agentic AI is the better model

We have said it before and will say it again: Human-led agentic AI is the ideal middle ground. There’s enough initiative to get proper value out of agentic AI, but there’s human oversight, accountability and judgement. In banking, this is an even bigger deal.

Human-led does not mean asking a person to approve every single step. People define the purpose, permissions, decision boundaries and escalation rules; the agent operates inside them. Humans remain accountable for high-consequence outcomes and can inspect, stop or reverse the system’s actions.

Is agentic AI right for banking?

Only for the right process, with the right authority, and the correct measures in place. 

As much as we’d love to put this kind of thing to the test in the real world, we’d need to run the agent in parallel on a real high-stakes user journey (essentially in shadow mode) while the traditional process keeps running in control. We’d then compare agent output to actual outcome, with no customer impact until it’s absolutely perfect. This gets us real performance data before handing over any authority.

Before you deploy any kind of AI agent, decide on which part of this outcome you can safely delegate and which part a human should continue to own.
