What banks should let AI do—and where to draw the line.
Welcome to FinTech Briefing. We bring together the developments and practical questions that matter to people building, buying and governing AI in financial services. This first edition examines a decision that cuts across banking and payments: how much authority should an AI system have?
An assistant that explains a product and an agent that initiates a payment may look similar on a screen. Their consequences differ. The second system needs a clear mandate, enforceable limits and a way to stop an action before an error reaches the customer.
Three signals from FinTech Central
Payment controls need to capture the mandate. Our recent analysis of agentic commerce examines identity, customer intent, permissions and liability. The practical question is whether the institution can reconstruct why an agent made a purchase and show that it stayed within the customer’s instructions. Read the analysis.
KYC is a useful test of where authority belongs. Gathering records and preparing a case file are different tasks from accepting a customer. Our private-banking article explores that boundary. Use it to examine which work an agent may perform and which decisions require an accountable reviewer. Explore agentic KYC.
Risk management has to cover the system in use. NIST’s voluntary AI Risk Management Framework supports trustworthiness across design, development, use and evaluation. It offers a starting point for organizing the questions a financial institution should ask, rather than a substitute for its applicable obligations. Read the primary source.
The decision behind the interface
Consider an illustrative instruction: find a suitable supplier and prepare a payment. Does that authorize the agent to add a payee, accept a price change or release funds? A system should not resolve those questions through inference alone.
Start by separating the workflow into specific actions. Searching public information, reading account data, drafting a recommendation and executing a transaction should each have their own permission. Where the task crosses a boundary, the system needs a rule for obtaining further approval.
Then describe the mandate in terms that the surrounding application can enforce. A spending ceiling is useful only if a control checks it. An expiry date matters only if expired authority stops working. A customer cancellation must reach the execution system, rather than remain as a message in a conversation.
The same discipline applies to evidence. A reviewer should be able to connect the instruction, the information available at the time, the permission granted and the action taken. That record helps the institution diagnose failures and explain an outcome. It should be designed alongside limits on access and retention.
Our editorial view: choose a small, useful workflow where these controls can be demonstrated. Expand authority when the team has evidence that the process works under difficult conditions. A convincing demonstration is the beginning of that assessment.
Questions for your next review
- Which actions can the system take without a fresh approval?
- Who defines those limits, and where are they enforced?
- What happens if instructions conflict or supporting evidence is missing?
- Can the customer or operator stop the workflow before execution?
- Who owns investigation and correction when an action is wrong?
Ask the team to demonstrate one rejected action and one successful cancellation. Seeing the boundary work is more useful than hearing that a human remains in control.
What to watch
Watch for workflows that quietly accumulate authority as new tools are connected. A feature update can turn a drafting assistant into a system that changes records or starts transactions. Treat that change as a new operating decision, with fresh tests and explicit ownership.
Also watch whether reviewers can challenge outputs in practice. A review step loses value when staff lack the evidence, time or authority to intervene.
