The Data Value Exchange in Wealth and Retail Banking

Open banking answered a technical question: customer data can move. It did not answer the commercial one: why would customers want it to?

That is now the real battleground for wealth and retail banking. Regulation can force access, but it cannot create adoption, loyalty or growth. If firms want customers to share more of their financial lives, they have to make the exchange feel fair, useful and immediate. In other words, they must turn open banking from a compliance exercise into a trust-building growth strategy.

The strongest institutions will not treat consent as a legal checkpoint. They will treat it as the start of a relationship—one in which control is visible, benefits are tangible and trust is earned interaction by interaction.

Customers share more data only when the return is obvious

Customers do not hand over richer financial data because an institution asks politely. They do it when the value in return is clear.

A narrow data set produces a narrow experience: a basic account view, a budgeting tool or a partial snapshot of financial life. That kind of exchange often feels underwhelming, especially when the data being requested is deeply personal. But when permissioned data expands to include current accounts, savings, lending, mortgages, insurance, pensions and even selected adjacent data sources, the institution can begin to understand the fuller picture of need, intent and timing.

That broader understanding makes a different class of service possible—one that is predictive, pre-emptive and genuinely relevant. The more specific and meaningful the service, the stronger the exchange becomes.

This matters particularly in wealth and retail banking, where customers increasingly expect life-first experiences rather than product-first interactions. They want support with buying a home, managing liquidity, planning for retirement, protecting their family or balancing short-term pressure with long-term goals. They do not think in siloed product categories, and they are less willing than ever to tolerate fragmented experiences that force them to join the dots themselves.

What a strong data value exchange looks like in practice

A credible value exchange is built as much through design and governance as through data science. Customers need to feel informed, in control and rewarded from the moment permission is requested.

1. Transparent consent journeys

Consent should not feel like a legal obstacle course. Customers should be able to see, in plain language, what data is being accessed, who is using it, why it is needed and how long access will last. Each permission request should be connected to a clear outcome, such as faster onboarding, easier identity verification, smarter cash management or more relevant financial guidance.

2. Benefits that are clearly articulated

The more personal the data, the more explicit the benefit must be. If a customer is asked to share rich account and product information only to receive a generic dashboard, the exchange feels one-sided. But if the same data enables frictionless onboarding, proactive support or tailored recommendations at meaningful moments, permission begins to feel worthwhile.

3. Privacy-by-design

Security and compliance are essential, but they are not enough on their own. Customers need confidence not only that their data is protected, but that it is being used responsibly and appropriately. Privacy-by-design means embedding governance, security and data minimization into the experience from the outset, rather than adding them after the fact.

Trust grows when customers can see that protection is part of the service, not hidden behind it.

4. Revocable permissions and visible control

Customers should be able to review, adjust and revoke permissions easily. They should not be forced into all-or-nothing choices or left uncertain about how to change their minds later. When permission feels reversible, data sharing feels less risky. When control is hard to find, trust erodes quickly.

5. Services that feel immediately useful

Convenience alone is not enough. The winning experiences will move beyond merely aggregating information and instead reduce friction, remove complexity and support better decisions in real time.

The aim is not simply to show customers more data. It is to help them do something better because that data is connected.

Where permissioned data creates the most value

When richer, permissioned data is activated responsibly, it can unlock high-value use cases across wealth and retail banking.

**Proactive cash-flow support** can help customers avoid distress before it happens. If an institution can identify that a customer is at risk of overdraft while holding funds elsewhere, it can prompt a transfer, suggest a better option or surface short-term support at the right moment.

**Smarter onboarding** can reduce friction by pre-populating information, validating identity through trusted sources and shortening the path from application to activation. This improves experience while lowering operational effort.

**Identification of product gaps and overlaps** becomes far more powerful when firms can see the wider financial picture. Customers may be over-insured in one area, under-protected in another, saving inefficiently, carrying expensive debt while holding surplus cash, or missing opportunities across pensions and longer-term planning. Connected data helps institutions uncover these issues and respond with relevance.

**More relevant guidance across savings, lending, insurance and pensions** is where the greatest long-term value sits. As more parts of the customer’s financial life become visible, institutions can broker better decisions between today and tomorrow, between immediate needs and later-life goals. Guidance becomes more contextual, more timely and more aligned to financial well-being.

This is especially important in wealth, where advice has historically been shaped by limited data sets, fragmented operating models and siloed teams. Richer, connected data creates the potential for a more complete view of the individual and a more joined-up relationship across planning, protection, borrowing and investing.

From rational trust to active trust

Banks have traditionally benefited from rational trust: customers believe their money will be safe, payments will work and balances will be accurate. That utility-style trust still matters, but it is no longer sufficient.

In a digital, ecosystem-driven market, firms are competing on a more demanding form of trust—one based on relevance, responsiveness and responsible use of data. A customer can keep an account open while shifting the relationship that matters to another interface, another platform or another partner. The institution still holds the account, but no longer owns the experience.

That is why open banking must be seen as a strategic opportunity, not a regulatory burden. Firms that remain at the level of minimum-compliant APIs risk becoming background infrastructure. Firms that use permissioned data to create connected, life-first services can deepen engagement and extend trust into new areas of value.

Turning consent into growth

Making the data value exchange work requires more than a better front end. It demands alignment across experience design, data strategy, technology, governance and operating model. Institutions need to break down silos, unify customer and product data, modernize the architecture that supports real-time interaction and create cross-functional teams able to turn insight into action responsibly.

Publicis Sapient helps financial institutions make that shift. We work across strategy, experience design, data and transformation to help banks and wealth managers design consent journeys that build confidence, create ecosystems that unlock richer value and turn data governance into a visible part of the customer promise.

The opportunity is clear: make control visible, make benefits tangible and make trust an active outcome of every interaction.

Because in wealth and retail banking, the future will not belong to the firms that simply gain access to data. It will belong to the ones that earn the right to use it.
