Beyond the Rate: Retail Banking's New Competitive Front

For most of retail banking's history, the competitive question was a simple one: who offers the best rate. Term deposits, mortgages, credit cards, the entire industry organised itself around a small set of numbers printed in comparison tables. That contest is nearly over. Open banking, rate-comparison platforms, and one-tap switching have compressed pricing into a commodity that any competitor can match within a news cycle. When everyone can see everyone else's rate, the rate stops being a strategy.

What remains to compete on is experience. Not experience in the soft sense of a pleasant app or a friendly call centre script, but experience as a first-order lever of growth: the thing that decides whether a customer activates their new account, whether they trust an offer enough to accept it, and whether they stay for the next ten years or quietly move their balance elsewhere. Retail banking's next decade will be shaped less by who has the sharpest rate and more by who understands, and acts on, the moment a customer is actually in.

This is a genuinely new problem for the industry, and it is worth pausing on why. Banking spent the better part of a century competing on access: more branches, more ATMs, more products on a shelf. It then spent two decades competing on digital convenience: a mobile app that worked, a faster loan approval, fewer forms. Both of those contests had a natural finish line, because eventually every serious competitor has a decent app and a nearby branch or a digital equivalent. Experience, understood properly, does not have a finish line. It compounds. A bank that reads customer behaviour well this quarter enters next quarter with a sharper hypothesis about what to test next, and the gap between it and a slower-moving competitor does not narrow, it widens.

The signal from the incumbents

Australia offers a useful case study in how seriously the largest institutions are now taking this shift. In 2021, Commonwealth Bank and data science firm Quantium launched CommBank iQ, a joint venture built on Australia's largest de-identified transaction dataset. The premise was straightforward: transaction data, properly analysed, reveals patterns in customer behaviour and the broader economy that neither a bank nor a pure analytics firm could see alone. CommBank iQ now offers insight products, decision-support tools, and AI-driven decision engines to institutions well beyond CBA itself.

More telling is what CommBank has done more recently with its own retail experience. In June 2026, the bank committed a further 140 million dollars to unify customer experience across digital, phone, and branch channels, funding branch refurbishments and upgrades focused on reducing wait times and expanding specialist support. The bank's own framing of the investment is instructive: the goal was described as making sure customers can get support in the way that suits them, and that the experience is consistent wherever they choose to engage, rather than favouring one channel over another.

Strip away the press release language and the strategic point is clear. CommBank is treating experience as infrastructure, on the same footing as core banking systems or capital allocation, not as a service layer bolted on after the product is built. That is a meaningful shift for an industry that has historically measured customer experience with an annual survey and called it done.

It is also a hedge against a specific competitive risk. CommBank iQ exists because CBA recognised that a de-identified transaction dataset, left unexploited, is a wasted asset sitting on the balance sheet. The 140 million dollar branch and channel investment is the same logic applied in the opposite direction: rather than only monetising what the bank already knows about customers externally through insight products, it is reinvesting in how well the bank understands and serves its own customers internally. Both moves come from the same premise, that the institution holding the richest, best-organised view of customer behaviour, not simply the institution with the most branches or the lowest rate, will set the pace for the category.

Why this matters well beyond one bank, one market

The same reframing is happening across financial services executive teams globally, and for good reason. Most large banks and insurers already have transaction data in abundance. What far fewer of them have is behavioural intelligence: a live, granular understanding of how a customer actually moves through a digital journey, where they hesitate, where they abandon, and what changes their mind.

The distinction matters more than it sounds. Transaction data tells you what happened. Behavioural data tells you why. A bank can see that a customer opened an account and never funded it. Only behavioural data can show that the customer opened the app four times in the first week, got as far as a specific verification screen, and left. That difference, between a fact and an explanation, is exactly where the next competitive advantage in retail banking sits.

This is also why the comparison with the rate war is a useful one, and not just a rhetorical device. A rate cut is visible to every competitor within hours and can be matched within days. A behavioural insight, properly acted on, is invisible to competitors by design, because it lives inside a bank's own product journey rather than in a published rate table. That asymmetry is precisely why the institutions moving first here are pulling ahead quietly rather than loudly. Nobody issues a press release when an onboarding screen is quietly rewritten because behavioural data showed where customers were getting stuck. But the effect on activation, and eventually on lifetime value, is often larger than anything a rate change could achieve.

What this looks like when it works

Two examples from digital-first banks, drawn from Amplitude's own customer base, show what this discipline looks like in practice when a smaller, faster-moving institution applies it without the balance sheet of an incumbent.

Salt Bank, Romania's first fully digital neobank, launched in 2024 to more demand than anyone expected: over 100,000 signups in the first week, three months' worth of growth in seven days. That popularity created its own problem. A large share of new customers were signing up but never activating their accounts. Digging into the behavioural data, and talking directly to customers, the growth team found the cause was not a broken product but a communication gap: many new customers assumed they needed their physical card to arrive before they could start paying digitally. Once the team redesigned the onboarding flow to make the digital wallet option unmissable, activations rose by 80 percent and the time to activation fell from several days to under one.

Salt Bank did not stop there. Behavioural data also revealed that customers were dropping out of the signup flow at the identity verification step. Rather than guess at a fix, the team tested two different approaches to the same screen and rolled out the version that performed better, which also reduced the bank's own third-party verification costs. A later cashback campaign, designed and measured the same way, lifted the share of customers making a purchase within seven days of joining by 50 percent. Within its first year, the bank had grown to twice its original projection, on the way to targeting a meaningful share of Romania's commercial banking market.

Xapo Bank, a global digital bank built around Bitcoin, faced a related but distinct problem. Its identity verification process was seeing significant drop-off, and the working assumption inside the business was that applicants were submitting poor-quality documents. Behavioural cohort analysis by country told a different story: in many regions, applicants simply did not hold the specific type of identity document the bank defaulted to requiring, a passport being far less universal than assumed. Once Xapo Bank partnered with identity verification providers who supported a wider range of document types by region, the number of applicants starting verification rose by 50 percent. Over the following year, the team ran around thirty separate experiments across the onboarding journey, in some cases doubling conversion at a single step.

Neither of these was a marketing insight or a design guess. Both were invisible until behavioural data made them visible, and both were fixed at a fraction of the cost of a rate cut or a national advertising campaign. It is also worth noting what these two institutions did not do. Neither ran a customer satisfaction survey to find the problem. Neither commissioned a research agency to interview a panel of users about their onboarding experience. By the time a quarterly survey would have surfaced either issue, both banks had already found the cause, tested a fix, and moved on to the next one. That speed, not the discovery itself, is the real advantage on display.

The reframe FSI executives need to make

The lesson from both the incumbent and the challenger is the same, even though the institutions are worlds apart in scale. Customer experience in banking is no longer principally about the interface. It is about understanding the specific moment a customer is in: why they hesitate at a compliance step, why they do not return after opening an account, why a well-designed offer goes ignored. That understanding requires combining what most banks already hold, transactional, risk, and compliance data, with something far fewer have organised well: real-time behavioural intelligence across every digital touchpoint.

This also changes how the investment case for experience should be made internally. For twenty years, customer experience has been funded as a cost centre, justified by a satisfaction score that moves slowly and proves little. The institutions pulling ahead now make the case differently. They connect experience investment directly to activation, retention, and lifetime value, the same growth metrics that used to belong exclusively to the product organisation. A 140 million dollar branch investment and an 80 percent activation lift from a smarter onboarding screen are, in this frame, the same kind of bet, just at different points on the balance sheet.

That reframing has a practical consequence for how APJ banks and insurers should structure their own teams. The organisations still treating customer experience, digital product, and data analytics as three separate reporting lines, each with its own roadmap and its own budget cycle, will find it structurally difficult to move at the speed Salt Bank or Xapo Bank moved. The behavioural signal that revealed the physical card assumption, or the passport assumption, only became actionable because a small team could see it, interpret it, and change the product in the same sprint. In a large institution split across product, compliance, marketing, and a central analytics function serving everyone equally, the same signal can take two quarters to travel from discovery to a shipped fix. By then, a faster competitor has already tested three more hypotheses.

What comes next

The institutions that treat experience as a static reflection of brand, refreshed every few years through a research study, will keep losing ground to those that treat it as a live system, one that reads customer behaviour continuously and updates itself in weeks rather than years. The rate war is over. The experience war has only just started, and unlike the rate war, this one rewards the banks and insurers willing to build the intelligence to actually win it.

The next question, and the subject of the piece that follows this one, is what happens when that intelligence stops being something a team consults and starts being something the product itself acts on: banking and insurance products that improve themselves with every customer they serve.
