Disintermediation and erosion of loyalty economics

As AI agents increasingly make frequent micro‑decisions on behalf of customers, banks without strong Agent Engine Optimization (AEO) and agent‑ready propositions risk being bypassed as engagement shifts from human‑led interactions to automated execution. Banks that rely on traditional marketing, cardholder prompts or human-centered user experience (UX) risk losing visibility and influence in payment decisions as AI intermediates the journey.

The rise of invisible commerce and its impact in risk

As transactions become background events, trust must be embedded (not manually verified). This shifts the center of gravity from user authentication to agent‑to‑institution authentication, continuous risk-monitoring and pre‑defined spending rules. Banks that do not redesign their authentication and dispute models for autonomous flows may expose themselves to operational, fraud and/or regulatory risks. Today’s systems can stretch to adopt passkeys, tokenization and standards like Visa Intelligent Commerce and Trusted Agent Protocol (TAP), but new models are needed for verifiable intent signatures, agent attestation, structured cart data and liability frameworks across human‑absent transactions.

Platform and ecosystem displacement

Large technology platforms will increasingly own the agentic layer, such as voice assistants, operating systems and personal AI companions. FIs lacking clear strategy may lose customer primacy as decisions shift to platform‑controlled agents. Those positioned only as commodity payment processors risk margin erosion and disintermediation.

This shift is already measurable:

Assisted commerce describes a model whereby AI supports and enhances human decision-making (e.g., recommending, ranking or partially executing actions), but the human user remains in control and must give final approval to transact. The next frontier — autonomous payments — will unlock real agentic commerce marked by asynchronous decisioning, complex workflows and AI systems capable of coordinating full end-to-end commercial actions on behalf of consumers and businesses.

While fully autonomous commerce will most likely require more time to materialize, assisted commerce has arrived.

However, this raises critical questions:

How do institutions ensure trust when users are not present at the moment of payment?
How must authentication, risk controls, data governance and dispute processes evolve?
What commercial models emerge when customers become AI intermediaries? And what infrastructure is needed to support high-volume, real-time autonomous decisioning at scale?

For financial institutions (FIs), agentic commerce creates both opportunity and urgency. Institutions that design intentionally for agent-driven commerce will remain relevant, while those that delay risk disintermediation as AI platforms intermediate commercial flows. This also elevates customer expectations, requiring banks to evolve beyond payments and build agentic banking capabilities across customer experience, productivity and risk management.

How financial institutions can compete in an agent‑first world

As with many other industry disruptions before, the strategic imperative is clear: Now is the time to establish a point of view and build the foundations. This article outlines the business implications of agentic commerce and provides a pragmatic roadmap for how financial institutions may unlock opportunity while also managing risk.

The transition to agent-driven payments represents perhaps one of the most consequential shifts since the emergence of ecommerce. For the shift to autonomous commerce to scale safely, several ingredients must align:

Consumer trust

structures such as permissions, boundaries, revocability or visibility

Merchant readiness

through catalogue accessibility, protocol participation and distribution strategies

Infrastructure evolution

especially across identity, intent, cart creation, authorization and liability allocation

FIs are likely to remain integral to the transaction flow through their roles in authorization, settlement and risk management; however, to stay relevant in agentic commerce, they will need to adapt legacy systems built for human-initiated interactions.

What are some foreseeable challenges?

: As AI agents increasingly make frequent micro‑decisions on behalf of customers, banks without strong Agent Engine Optimization (AEO) and agent‑ready propositions risk being bypassed as engagement shifts from human‑led interactions to automated execution. Banks that rely on traditional marketing, cardholder prompts or human-centered user experience (UX) risk losing visibility and influence in payment decisions as AI intermediates the journey.
: As transactions become background events, trust must be embedded (not manually verified).

FIs lacking clear strategy may lose customer primacy as decisions shift to platform‑controlled agents. Those positioned only as commodity payment processors risk margin erosion and disintermediation.

Opportunities also exist for new value creation. Institutions that act early can tap into meaningful advantages by using agentic technologies for commerce and beyond:

New product models like autonomous budgeting, AI-led liquidity optimization, smart credit line tuning and bank-led marketplaces
Embedded finance at scale accelerated by agents that transact on behalf of businesses
Deeper customer loyalty via personalized financial guardianship managed by trusted bank-aligned agents, as well as hyper-relevant rewards
Opperational efficiencies through automation of routine financial decisions and operations

Agentic commerce is not merely a technology trend — it is a business model shift. FIs that embrace it can create new competitive differentiators rooted in intelligence, trust and seamless integration. Those that ignore it may find themselves competing for relevance in a market where agents, not consumers, choose the financial partner.

A three-pillar strategy for the agentic era

FIs can better prepare for agentic commerce by adopting a three-pronged strategy that enhances an assisted commerce role today, while also preparing them for autonomous commerce tomorrow.

Build the intelligent payment architecture for autonomous agents

Six foundational layers of agentic payments require adaptation:

intent extraction and structured payment instructions
agent identity (KYA) and attestation models
cart creation and merchant validation flows
delegated credential provisioning (e.g., pass through tokens)
authentication evolution
risk modelling and new liability models

Protect existing propositions and build agentic banking capabilities across experience, productivity and risk

To protect existing propositions and top-of-wallet positioning, banks must rethink SEO and embrace AEO. Leveraging transaction insights and analytics, banks should also identify opportunities for products designed for delegation, such as the following:

autonomous subscription management
AI-guided credit optimization
proactive smart savings automation and cash flow orchestration
agent compatible loyalty and incentives framework

Strengthen ecosystem positioning through partnerships and protocol participation

This involves evaluating emerging agentic commerce protocols (e.g., VIC, AP2, x402) and merchant-integration patterns, revising strategies and partnership models to ensure issuers remain embedded in agent workflows rather than being bypassed by them.

Together, these three pillars create an actionable strategy for capturing value, reducing risk and keeping pace with the future of digital commerce.

Designing the future of payments

Agentic commerce is advancing rapidly. Consumers are demonstrating early readiness, merchants are experimenting, and ecosystem players are rapidly closing the infrastructure gaps required for autonomous payments. For FIs, this moment mirrors the inflection point seen in other transformative shifts, such as mobile payments, where early strategic clarity became a differentiator.

The institutions that act now will help define how autonomous payments function, secure their roles in AI-mediated decision flows, and shape the trust, identity and risk standards of this new commercial era. Those who wait risk losing visibility, influence and commercial relevance as agents become the new interfaces for everyday spending.
