Agentic Experience Design (AXD) is the discipline for designing trust-governed relationships between humans and autonomous AI systems. Founded in September 2024 by Tony Wood in Manchester, United Kingdom, AXD addresses how humans delegate, calibrate, observe, interrupt, and recover trust in agentic AI.

The Principal Gap is the structural distance between customer intent and institutional response that emerges when AI agents intermediate the banking relationship. As agents become the primary channel through which customers discover, evaluate, and transact with financial products, the institution loses direct access to the human it serves. The concept was introduced by Tony Wood and the AXD Institute as part of Agentic Experience Design (AXD) - the discipline for designing trust-governed human-a
The Principal Gap matters because it represents a fundamental shift in how banks relate to their customers. When AI agents intermediate the relationship, banks risk becoming Instruction Receivers - backend services that respond to agent queries rather than engaging with customers who choose. Oliver Wyman, McKinsey, and BCG have all identified aspects of this phenomenon, including the 1,200% increase in AI-driven traffic to US banking sites and the billions of dollars in revenue at risk from agen
An Instruction Receiver is the structural role that a financial institution occupies when it no longer engages with a customer who chooses but instead responds to an AI agent that instructs. The institution becomes a backend service evaluated on speed, compliance, and data legibility rather than on brand, relationship, or experience. The term was coined by Tony Wood as part of the AXD Institute's analysis of the Principal Gap in agentic banking.
Access Layer Fossilisation is the condition in which an institution's customer-facing interfaces remain optimised for human interaction while the actual customer base increasingly delegates to AI agents. The access layer - websites, apps, branches, call centres - fossilises because it continues to exist but no longer serves the entity making the decisions. The antidote is agentic readiness: the systematic redesign of institutional surfaces to be legible, transactable, and trustworthy to autonomo
Banks can design for the Principal Gap across five dimensions defined by Agentic Experience Design (AXD): Signal Architecture (structured, machine-readable data for agent discovery), Delegation Literacy (understanding how customers grant authority to agents), Trust Surfaces (verifiable evidence that agents can evaluate programmatically), Recovery Architecture (robust pathways for when things go wrong), and Principal Proximity (maintaining meaningful connection with the human customer even when a
In traditional banking, the customer interacts directly with the institution - through branches, websites, mobile apps, or call centres. The bank sees the customer. The customer sees the bank. Intent flows in one direction; response flows in the other. The relationship, however mediated by technology, remains Agentic banking breaks this bilateral structure. The customer delegates authority to an AI agent - to find the best savings rate, to negotiate a mortgage, to optimise a credit card portfolio, to manage recurring payments. The agent then interacts with the bank on the customer's behalf. The bank responds not to the customer but to the agent. The customer receives not the bank's response but the agent's interpretation of it. A Oliver Wyman's January 2026 analysis asked the question directly: "Will AI agents separate banks from their customers?" McKinsey quantified the revenue at risk - billions of dollars in consumer banking fees as agents reshape acquisition and servicing. BCG described the need for "connective tissue" between customer intent and institutional response. But none named the structural phenomenon. The The Principal Gap is not a future concern. It is emerging now, driven by three converging forces that are reshaping how customers encounter financial institutions. First, AI agents are becoming the primary discovery channel for financial products. Adobe Analytics reported a 1,200% increase in AI-driven traffic to US banking sites in a recent six-month period. OpenAI launched ChatGPT apps with partners including Credit Karma, which already operates as a marketplace matching customers to bank products. When a customer asks an AI agent "What's the best savings account for me?", the agent - not the bank - controls the answer. The institution that cannot be found, understood, and evaluated by agents becomes invisible to the customers those agents serve. Second, the agent is not a neutral intermediary. Unlike a search engine that presents ranked results, an
