The Economics of Customer Ownership in an Open Financial System

As payments become shared infrastructure and financial information becomes more portable, the bank can retain the account while losing part of the economics that historically accompanied the relationship. This article examines how customer primacy is changing when balances, flows, interface, information and financial decisions no longer need to reside within the same institution.

The bank can retain the account and still lose part of the economics surrounding the customer relationship.

For most of modern banking, the payment relationship and the banking relationship were difficult to separate. The institution that held the customer’s account also provided the payment instrument, processed much of the customer’s financial activity, accumulated the resulting behavioural information and occupied the position from which the next financial product was most likely to be sold. Payments were therefore not merely a transactional service. They were part of the economic architecture through which banks acquired funding, understood customers, generated fees and preserved the primacy of the relationship.

That architecture is becoming less integrated. Fast payment systems are increasingly shared infrastructure rather than proprietary bank capabilities. Open banking and open finance are making customer-permissioned information more portable. Digital wallets and third-party applications can control the payment experience while regulated accounts remain underneath. Embedded financial propositions can place payment initiation inside commercial journeys that do not belong to a bank, while intelligent software is beginning to create a new decision layer above the interface itself.

None of this requires banks to disappear from payments. Banks can continue holding deposits, settling transactions, extending credit and providing regulated infrastructure while another institution increasingly controls the moment at which the customer decides what to do with money. The strategic issue is therefore not whether banks will continue to participate in payments, but whether participation alone is sufficient to preserve the economics that historically accompanied the payment relationship.

This distinction matters because a payment contains more than a transfer of value. It contains evidence of financial intent, produces behavioural information, helps create operating balances, reveals emerging product needs and frequently determines which institution occupies the primary position in the customer’s financial life. If those functions migrate while the underlying account remains, a bank can retain the customer in an accounting sense while losing part of the economics that once made the relationship valuable.

The central question for bank leadership is therefore becoming more precise: which parts of the payment relationship create economic control over the customer, which of those functions are becoming separable from the account, and what happens to funding, fees, pricing power, cross-sell and customer profitability when they move elsewhere? That is where the future of payments becomes Future Banking Economics.

Payments Were Never Only About Moving Money

A payment appears operationally simple because value moves from one party to another, the transaction is authorised, accounts are updated and settlement occurs through established infrastructure. Its economic significance is considerably larger because every payment also records behaviour. It can reveal that a customer has received salary, paid a supplier, purchased inventory, settled a tax obligation, travelled, made a mortgage instalment, transferred savings or begun interacting with a new merchant. Across millions of transactions, those events produce a rich picture of how households and businesses function economically.

The institution closest to those flows therefore possesses more than transaction volume. It acquires visibility into financial intent. For a bank, that visibility can support several economics simultaneously. Merchant settlement, payroll, collections and cash management can create operating balances that strengthen funding. Transaction information can improve credit assessment and customer segmentation. Payment activity can generate direct fee income, strengthen retention and create opportunities for lending, wealth, insurance, foreign exchange and other services.

This explains why the value of a payment relationship cannot be measured adequately through payment revenue alone. A corporate payments mandate may produce modest direct fees while anchoring deposits, foreign exchange, trade finance, working-capital lending and treasury activity. A retail payment relationship may generate limited direct revenue while establishing the bank as the primary institution through which income arrives, bills are paid and financial choices are made. In both cases, the strategically valuable asset is not the isolated transaction but the economic position surrounding it.

Historically, banks captured much of this position because account ownership, payment execution, customer data and distribution were tightly connected. The structural change underway is separating these functions, which means that the bank can continue processing the payment after part of the economic relationship has moved somewhere else.

The Payment Relationship Is Being Unbundled

The emerging payment architecture can be understood through four economic layers. At the foundation sits the regulated account or store of value. Above it sits the rail through which money moves. Above the rail sits the interface through which the customer initiates and manages financial activity. Increasingly, another layer is forming above the interface: the decision layer through which the customer discovers, compares and chooses what financial action to take.

These layers no longer need to belong to the same institution. A bank can hold the deposit, a national fast payment system can move the funds, a third-party application can initiate the payment and an external platform can control the commercial journey within which the transaction occurs. As intelligent financial agents mature, the decision itself may begin before any provider-specific banking interface is opened.

Research from the Bank for International Settlements illustrates why this matters competitively. A study covering 86,163 finance applications across 95 countries found that the introduction of retail fast payment systems was associated with greater adoption of digital financial applications, with the effect particularly visible among fintech and technology-led entrants. The significance of fast payment infrastructure therefore extends beyond speed. By lowering infrastructure friction and supporting broader participation, it can change who is able to compete for the customer relationship.

This is not inherently adverse for banking systems. Shared infrastructure can increase efficiency, competition, inclusion and innovation. For an incumbent bank, however, it changes the basis of advantage because owning the account no longer guarantees ownership of the payment experience, while owning the payment experience no longer guarantees control over the customer’s financial decision. The customer relationship becomes layered rather than binary, and strategy must determine which layers remain economically necessary for the institution.

Customer Ownership Is Not The Same As Account Ownership

The language of customer ownership is frequently used too loosely in banking because no institution literally owns a customer. The economically relevant issue is whether the bank occupies a sufficiently strong position to influence financial behaviour, retain a disproportionate share of activity and capture the resulting economics. Bancly describes this condition as Customer Economic Primacy.

Customer Economic Primacy exists when an institution controls enough of the customer’s balances, financial flows, interface, information and future decision process to influence where economic value is created and captured. This is more demanding than holding an account because the bank can possess the regulated customer relationship while another provider increasingly controls the context in which financial choices occur.

Consider a customer whose salary continues to enter a traditional bank account but who increasingly uses an external application to view finances across institutions, initiate payments, compare credit offers, optimise savings and decide where excess liquidity should sit. The bank retains the account and may continue processing much of the underlying activity, yet another provider increasingly sees the customer’s financial position in aggregate and gains the opportunity to influence the next decision.

Open finance makes this separation more plausible because it changes the economics of information. BIS research published in 2026 finds that customer-permissioned financial data sharing can reduce information asymmetries, break down data silos and support market entry, provided that interoperability, standardisation and appropriate regulatory safeguards are in place. The implication for incumbent banks is that customer knowledge becomes progressively less captive to the institution that originally generated the data.

The advantage therefore moves from possession towards interpretation. A bank that historically benefited because competitors could not see the same customer information must increasingly compete on whether it can convert information into better decisions, stronger propositions and more attractive economics. Data remain valuable, but data possession alone becomes a weaker moat when the customer can authorise others to use comparable information.

Fast Payments Change More Than Payment Speed

The strategic significance of fast payment systems is sometimes underestimated because the immediate benefit appears operational. A transaction that previously took hours or days can be executed almost instantly, around the clock and often at very low cost. The larger consequence emerges when instant movement becomes common infrastructure rather than a differentiating capability.

Speed reduces the need to hold precautionary balances in particular places. Interoperability reduces friction in moving funds among institutions. Open participation can enable non-bank providers to offer payment experiences while relying on shared settlement infrastructure underneath. Lower transaction costs can also make new commercial models viable even when payment margins themselves are limited.

The BIS study of retail fast payments finds that adoption of digital finance is particularly strong where systems combine active central-bank involvement, real-time settlement and relatively open participation. This matters because payment infrastructure can become a catalyst for financial competition outside payments. A customer may initially adopt an application because it provides a convenient way to pay, then subsequently use the same interface for savings, credit, investment or insurance. The payment relationship becomes a distribution channel for other financial products.

Theoretical BIS work on competing digital monies reaches a related conclusion. Interoperable fast payment infrastructure can improve inclusion and system efficiency while also allowing non-bank payment providers to gain market share from incumbent intermediaries. The system-level outcome can therefore be positive while the distribution of commercial economics among providers changes materially.

Bank strategy should not respond by opposing open infrastructure. The relevant task is to understand where advantage moves once infrastructure itself becomes less differentiating. If the rail is shared, the interface, information layer, decision quality and relationship economics become more important sources of competitive position.

The Interface And The Decision Layer Are Becoming Economic Assets

Banks have invested heavily in digital channels, and much of that investment has been justified through convenience, service quality, branch migration and lower cost-to-serve. Those benefits remain important, but the strategic value of the interface is larger because the interface is where financial intent becomes observable before the transaction occurs.

A customer opening an application to transfer money, investigate a mortgage, review investments or pay a merchant is communicating something economically useful before a product has necessarily been selected. The institution controlling that interaction can influence which balance is used, which provider receives the fee, whether credit is offered, whether excess liquidity remains within the relationship and which additional service becomes relevant next.

This makes interface ownership economically distinct from account ownership. A bank can operate the regulated account and settlement relationship while another provider controls discovery and initiation. The bank may still earn part of the economics, but it no longer determines how the customer arrives at the financial decision. Distribution economics have therefore become strategically independent from product manufacturing economics.

A further shift is now becoming conceivable as intelligent software begins to sit above the financial interface. The relevant question is not whether every payment will become autonomous, but whether financial discovery, comparison and initiation increasingly occur through an external decision layer that can evaluate several providers at once. If that occurs, the bank’s digital application may no longer be the first point at which customer intent becomes visible.

The implications extend well beyond technology. An institution that loses the decision layer may continue providing regulated products while competing more aggressively on price because another interface controls customer acquisition and choice. Conversely, a bank that preserves decision influence can retain pricing power, cross-sell and relationship depth even if some underlying infrastructure becomes shared.

The Payment Fee May Be The Least Important Economic Question

Payment economics are naturally discussed through transaction fees, interchange, merchant pricing and the cost of operating payment infrastructure. These remain material businesses, particularly at scale, but the strategic value of payments can be misunderstood if the analysis ends with the fee attached to the transaction.

BIS research on fast payment pricing demonstrates why the issue is broader. Pricing structures vary considerably across systems and participants, while zero-fee models can be difficult to sustain without external subsidies or alternative revenue streams. The implication is that payment activity can be rational even when the direct transaction margin is modest if the provider captures economic value somewhere else in the relationship.

For banks, those adjacent economics can include deposits, credit, foreign exchange, merchant services, wealth, insurance, transaction data and customer retention. A zero-margin payment can therefore be economically attractive if it anchors a broader relationship, while a profitable payment can have limited strategic value if another provider controls the interface, information and next-product opportunity.

The appropriate unit of analysis becomes relationship economics rather than transaction economics. This is particularly important in corporate and SME banking, where payment flows can reveal revenue cycles, supplier relationships, payroll patterns, liquidity needs and working-capital behaviour. Losing visibility into those operating flows can weaken credit intelligence and relationship pricing even if the bank retains the loan itself.

The strategic problem is therefore not simply that payments become cheaper. It is that payments can stop producing relationship advantage for the institution that still processes them.

The Five Layers Of Customer Economic Primacy

The changing architecture requires a more precise framework for understanding the economic position of a bank around the customer. Five layers are especially important because they describe progressively deeper forms of control over the relationship.

The first is Balance Ownership, which means that the institution holds the customer’s deposit, credit or other regulated financial claim. The second is Flow Ownership, which means that a meaningful share of recurring financial activity passes through the institution. The third is Interface Ownership, which means that the customer regularly enters the institution’s environment when initiating or managing financial activity. The fourth is Information Advantage, which means that the bank sees enough of the customer’s financial life to make better decisions than competing providers. The fifth is Decision Influence, which means that the institution is present before the customer’s next financial choice is made.

Historically, these positions often accumulated inside the same bank. The future architecture allows them to separate. A bank can possess Balance Ownership without Interface Ownership, while a payment application can possess Interface Ownership without holding the regulated balance. An open-finance platform can develop Information Advantage across several institutions, and an intelligent financial assistant could eventually exercise Decision Influence without manufacturing a financial product itself.

This framework does not imply that banks should attempt to own every layer in every segment. Shared infrastructure can create efficiency, external distribution can expand reach and partnerships can improve economics where the bank’s comparative advantage lies in trust, regulation, credit or balance-sheet capacity rather than customer interface. The discipline is to distinguish deliberate distribution from accidental commoditisation.

A bank can intentionally provide regulated infrastructure through an external ecosystem because the resulting economics remain attractive. That is a strategic choice. A bank that gradually loses customer access while assuming that account ownership still guarantees the relationship is experiencing something entirely different.

The Customer Can Stay While The Economics Move Elsewhere

The most dangerous competitive shifts are often those that do not initially appear in conventional banking metrics. A bank can retain millions of accounts, report stable deposits, process growing payment volumes and show increasing digital activity while its structural position around the customer becomes weaker.

Suppose that an increasing share of customers use third-party applications to initiate payments and view financial information. Merchant activity begins more frequently inside large digital ecosystems. Product comparison occurs through aggregators. Customer-permissioned data allow external providers to understand income, expenditure and investment behaviour across several institutions. The bank continues processing much of the activity underneath this ecosystem but receives fewer opportunities to influence the customer before a decision is made.

Nothing has necessarily disappeared from the balance sheet. The economics of customer primacy may nevertheless have changed. The bank still holds the account but increasingly receives the transaction after somebody else has shaped the decision. It still possesses data but no longer enjoys the same informational exclusivity. It still has the customer but may capture less cross-sell, weaker pricing power and fewer opportunities to own the next financial need.

This is the payments equivalent of the distinction between financial performance and structural economic position. Customer numbers can remain healthy while customer economics deteriorate. Payment volume can rise while the bank’s relative control over financial intent declines. Digital engagement can remain strong while another platform becomes the environment in which economically important decisions are made.

For this reason, active users, payment volume and account retention should be supplemented with evidence of relationship depth, flow primacy, decision influence and the financial contribution produced by those positions.

Open Finance Changes The Economics Of Information

Open banking began by allowing customers to authorise access to banking information and, in some frameworks, initiate payments through third parties. Open finance extends the principle towards a wider set of financial information, including investments, insurance, pensions and other assets and liabilities. Its economic importance comes from what happens when information becomes more portable.

Banks have historically benefited from information generated inside their own relationships. An institution seeing salary receipts, spending patterns, deposits, borrowing and repayment behaviour has an advantage over a competitor that sees none of those signals. Customer-permissioned data sharing can reduce that asymmetry by allowing alternative providers to assemble a broader picture of the customer.

BIS analysis of international open-finance experience finds early evidence that these frameworks can reduce data silos, support new forms of intermediation and increase competition, while successful implementation depends on common standards, interoperability and robust regulatory design. This is beneficial to customers because information that was previously trapped within individual institutions can support better financial products and greater access.

For incumbent banks, the strategic implication is that historical customer data cannot automatically be treated as a durable moat. The advantage increasingly moves towards analytical quality, trust, proprietary insight, integration with operating flows and the ability to convert information into better financial decisions. The relevant capability becomes decision advantage rather than data accumulation alone.

This also changes the economics of scale. A large bank may possess more historical data than a smaller entrant, but if the entrant can access customer-permissioned information across several providers and convert it into a more relevant decision experience, raw data volume may not translate automatically into customer primacy. Scale remains valuable, but the way it creates advantage is changing.

A Customer Economic Primacy Scorecard

Conventional customer metrics remain essential. Active customers, payment volume, products per customer, deposits, fee income, retention and digital usage all provide useful information about the franchise. They do not, however, fully describe whether the bank continues to occupy the economic position from which future customer value is created.

A more complete scorecard should examine at least five dimensions. Flow Primacy should measure how much of the customer’s recurring financial activity passes through the institution and whether those flows generate deposits, fees and information. Interface Primacy should assess whether customers initiate meaningful financial activity through the bank or whether bank-owned applications increasingly operate as utilities supporting decisions made elsewhere.

Information Advantage should evaluate whether the institution can understand the customer’s financial position and behaviour better than competing providers even as data become portable. Decision Influence should examine whether the bank is present before the customer’s financial choice is made or merely fulfils a decision originated elsewhere. Relationship Economics should connect the entire position to funding, fee income, credit conversion, cross-sell, retention and customer profitability.

This scorecard creates a more useful management question because the objective is not simply to maximise payment transactions. It is to determine whether participation in payments strengthens or weakens the institution’s economic position around the customer, and whether the resulting position justifies the investment, pricing and capital used to sustain it.

From Payments Strategy To Customer Primacy Governance

The changing economics of payments require the CEO and board conversation to move beyond the traditional boundary between payments strategy, digital strategy and customer strategy. Transaction volumes should continue to be governed, but leadership should understand which flows create deposits, behavioural information, cross-sell and broader customer profitability.

Digital-channel adoption should continue to matter, while management also determines whether the institution remains the customer’s primary financial interface or whether bank-owned applications increasingly support decisions initiated elsewhere. Open banking and open finance should continue to be governed as regulatory and infrastructure questions, but boards should also understand how data portability changes the competitive value of historical customer information.

Embedded distribution and partnerships can create attractive growth, but management should distinguish arrangements that deliberately extend the bank’s economics from those that progressively transfer customer primacy to another institution. Payment pricing remains important, but leadership should know when low-margin payment activity creates high-value relationship economics and when profitable transaction volume conceals weakening control over the customer.

Artificial intelligence also belongs within this governance framework. The strategic question is not simply whether the bank deploys an intelligent interface of its own. It is whether the customer’s first financial interaction increasingly occurs through an external decision layer capable of comparing providers, reallocating balances and recommending actions across institutions. The bank must understand what happens to acquisition economics, pricing power and cross-sell if that layer becomes influential.

The governing question is therefore no longer whether the bank has a payments strategy. It is whether the institution knows which parts of the payment relationship are economically necessary for preserving customer primacy, which can be shared without destroying value and which should be surrendered deliberately because another configuration produces superior economics.

When Payments Stop Belonging To Banks

Payments are unlikely to stop involving banks because commercial banks remain deeply embedded in deposit creation, settlement, credit, liquidity, regulation and financial trust. Even where non-bank providers control customer interfaces, regulated banking infrastructure frequently remains underneath the transaction. The structural change is more subtle because payments can stop belonging exclusively to the bank.

The rail can become shared infrastructure, the interface can belong to another provider, customer data can become portable and financial discovery can occur through an external platform. The bank therefore does not need to disappear from the payment for the economics of customer ownership to change. It can remain economically important while becoming less influential over how the customer chooses, allocates and combines financial products.

This changes the strategic objective. A bank does not need to manufacture every payment capability or own every customer interface. It does need to understand which positions generate funding, information, decision influence, cross-sell and customer profitability, and which of those positions it is willing to surrender because the economics remain attractive without them.

The strongest institutions will make those choices deliberately. Some banks will preserve customer primacy through superior transaction banking, payments and integrated financial relationships. Others will operate successfully as regulated manufacturers distributed through external ecosystems. Many will combine both roles across different customer segments and profit pools. The economically dangerous position is not necessarily becoming less visible to the customer. It is becoming less visible without understanding what economic value is being transferred in the process.

The central question for leadership is therefore whether the bank can continue capturing attractive economics when the account, rail, interface, information and financial decision no longer need to reside within the same institution. That question determines who sees financial intent, who controls the recurring flows that create deposits, who captures the next product opportunity and ultimately who owns the economics of the relationship.

The future competition is not simply for the transaction. It is for Customer Economic Primacy, and as the financial architecture becomes more open, that position will increasingly need to be earned rather than assumed.
