How should banks respond when BigTech firms can acquire users at scale and bundle financial services into existing digital habits?

Why BigTech bundling changes the competitive battlefield

BigTech does not compete with banks only on price or product breadth. It competes by owning the daily context in which payments, shopping, messaging, and device use already happen. That changes acquisition economics: customer attention, interface control, and trust cues can become more important than balance-sheet strength or branch presence.

For banks, the practical implication is that distribution is no longer separable from product design. If the customer experience feels disconnected from the moment of need, the bank loses before the product comparison even starts. The response is to make the bank easier to choose inside existing routines, not just better in a standalone sales pitch.

What banks should change in the customer relationship

The strongest response is to reduce friction at the points where customers decide whether a service is worth adopting. That means simpler onboarding, clearer pricing, faster approvals, and journeys that work well on mobile without forcing the customer to relearn the bank’s process for every product.

Trust also has to become more operational. When identity proofing, authentication, and authorization are clumsy, customers feel the bank is making convenience expensive. When those controls are modern and low-friction, the bank can protect itself without turning every interaction into a hurdle. For customer-facing identity controls, banks should treat the access path as part of the product, not a back-office afterthought, and align it with NIST Cybersecurity Framework 2.0 and NIST SP 800-53 Rev 5 Security and Privacy Controls.

Banks should also use context better. That can mean pre-approved offers, embedded payments, personalized savings prompts, or account services that appear inside the customer’s existing digital flow. The goal is not to copy BigTech’s ecosystem, but to make the bank useful at the moment the customer is already taking action.

How trust, data, and ecosystem control shape the bank response

BigTech bundling works because it reduces the number of decisions a customer has to make. Banks need to counter that by becoming easier to trust across channels, partners, and devices. In practice, that means stronger proof of who is accessing the account, tighter control of data sharing, and better governance over third-party integrations that extend the banking experience.

In cloud and platform-heavy delivery models, workload and service identities often become part of the trust boundary. Where those identities support customer journeys, banks should know which services can authenticate, what they can reach, and how quickly access can be revoked if something changes. For that reason, the underlying control model matters as much as the front-end design, and banks can use SPIFFE workload identity specification as a reference point for service-to-service trust. Broader resilience and third-party risk expectations are also reinforced by EU Digital Operational Resilience Act (DORA).

For customer data, the priority is not collecting more, but using less in a more intentional way. Banks that can explain why a data element is needed, how it is protected, and how it improves service are better positioned than firms that simply accumulate profiling data without visible customer value.

Risk and Threat Considerations

The main risk is that banks respond too slowly or treat BigTech as a product-comparison issue rather than a trust and distribution shift. If the bank’s customer journey remains fragmented, customers will migrate toward the actor that is easiest to reach, easiest to use, and hardest to replace.

Failure mechanism: Weak onboarding, brittle identity controls, and poor ecosystem integration create friction that pushes users into bundled digital channels where the bank becomes a background utility instead of the primary relationship.

Impact: The bank loses acquisition, engagement, and cross-sell opportunities, while also increasing the pressure to accept riskier shortcuts just to stay convenient.

Practitioner Guidance

What to prioritise: Focus first on the parts of the journey that determine whether a customer completes onboarding, logs in repeatedly, and accepts an embedded offer. If those steps are slow or confusing, feature additions will not offset the churn.

What to verify: Check whether identity proofing, step-up authentication, and account recovery can be completed with low customer effort and clear exception handling. If support tickets cluster around access or verification, the trust layer is undermining adoption.

Practitioner takeaway: Banks do not beat BigTech by defending legacy channels more effectively; they win by making trust, access, and usefulness visible in the moments customers already live in.
