In short: Alternative data (Open Banking, transaction data, payroll, accounting platforms) is becoming a commodity as access widens across the industry. The real competitive advantage now comes from the models that turn that data into decisions, not from the data itself. Lenders who invest in lender-specific modeling, rather than generic scores, are the ones best positioned to improve approvals, pricing, and portfolio performance over the next decade.
Over the past decade, alternative data has fundamentally changed how lenders assess credit risk. Open Banking, transaction data, payroll data, accounting platforms, and other emerging data sources have given lenders a richer understanding of borrowers than traditional credit bureau data alone.
This has been an important evolution. Many lenders have improved decision making by incorporating cash flow behavior, income stability, and real-world financial activity into their underwriting processes. Alternative data has also opened new opportunities to assess borrowers with limited credit histories, irregular income, or characteristics that are not fully reflected in a traditional credit file.
As a result, many lending strategies today focus on one question:
What additional data should we use?
It is a reasonable question, but increasingly it is no longer the most important one.
As access to alternative data becomes more common, the competitive advantage is shifting. Open Banking is becoming standard across many markets. Transaction enrichment is widely available. Payroll integrations continue to expand. The data itself is becoming easier to obtain.
The next question lenders should be asking is far more valuable.
How can we make better lending decisions with the data we already have?
The answer lies in the models, not the data.
These two concepts are often discussed together, but they solve very different problems.
Alternative data expands the information available to a lender. It answers questions such as:
Alternative models answer an entirely different set of questions.
This distinction matters because raw data does not predict lending outcomes. Models do.
A lender can collect thousands of variables about an applicant, but until those variables are transformed into an accurate and explainable prediction, they remain just data.
The value is created by converting information into decisions.
Imagine three lenders evaluating exactly the same applicant.
All three receive identical transaction data through the same Open Banking provider. They have access to the same balances, income streams, recurring expenses, and account history.
Yet they make three different decisions.
One approves the application.
One declines it.
One approves it, but offers a smaller limit with different pricing.
Nothing changed about the borrower.
Nothing changed about the data.
Only the model changed.
This happens every day because lenders optimize for different objectives. They serve different customer segments, offer different products, operate with different funding costs, maintain different risk appetites, and measure success in different ways.
A wage advance provider is solving a different problem from a personal loan lender. A credit union has different objectives from a fintech. A small business lender evaluates different risks from a consumer lender.
Expecting one generic model to perform equally well across all of these businesses is like expecting one pricing strategy to work across every product.
The competitive advantage does not come from owning the data.
It comes from building models that are designed around the lender's own products, customers, and commercial objectives.
There is a common assumption that adding another data source will naturally improve model performance.
Sometimes it does.
Often it does not.
Every additional dataset introduces more variables, more interactions, and more complexity. Without careful feature engineering, validation, and model development, additional information can simply introduce more noise rather than more predictive power.
This is one reason many lenders find themselves collecting increasingly large volumes of data without seeing a corresponding improvement in portfolio performance.
The challenge is rarely collecting information.
The challenge is identifying which borrower behaviors genuinely predict future outcomes.
That requires statistical modeling, domain expertise, rigorous validation, and continuous monitoring. In other words, it requires better models rather than simply more inputs.
Credit risk professionals rightly spend considerable time measuring model performance using metrics such as AUC, Gini, KS, and calibration.
These metrics matter.
However, executives do not invest in better models because they want a higher Gini coefficient.
They invest because they want better commercial outcomes.
A stronger model should help lenders make better decisions across the entire credit lifecycle. That may mean approving more creditworthy borrowers without increasing losses. It may mean identifying hidden risk earlier, assigning more appropriate loan amounts, improving pricing decisions, reducing unnecessary manual review, or allocating capital more efficiently.
Ultimately, the objective is not to produce a more sophisticated score.
It is to improve the economics of the lending business.
The best models create measurable improvements in approval quality, portfolio performance, customer experience, and profitability.
Off-the-shelf models play an important role within the industry and often provide meaningful value.
However, every generic model is built using assumptions that reflect a broad population rather than a specific lender.
Over time, most lenders reach a point where incremental improvements become difficult because the model was never designed around their particular business.
Every lender has its own mix of products, customers, acquisition channels, pricing strategies, funding costs, servicing approach, and portfolio objectives.
Those differences matter.
A lender focused on near-prime borrowers should not optimize risk in the same way as a prime lender. A revolving credit product should not necessarily be modeled in the same way as a fixed-term installment loan. A small business lender will often care about different signals than a consumer lender.
The more a model reflects the characteristics of a lender's own portfolio, the more opportunity there is to improve risk separation and ultimately business performance.
For many lenders, the greatest opportunity is no longer finding another source of data.
It is extracting more value from the data they already possess.
Most organizations already have access to a rich combination of bureau information, application data, internal repayment history, transaction data, and portfolio performance. Yet many continue to make decisions using models that were developed years ago or were designed for a much broader market.
This is where lender-specific modeling becomes valuable.
Rather than asking every lender to use the same score, a tailored credit risk model is designed around the lender's own products, historical outcomes, risk appetite, and commercial objectives. They can be calibrated to optimize for the outcomes that matter most to that organization, whether that is approval growth, portfolio quality, profitability, pricing, limit assignment, or lifecycle management.
The objective is not simply to produce a different score.
It is to build a model that helps the lender make consistently better decisions.
Modern lending decisions extend well beyond the initial approval.
The same behavioral signals that help determine whether an applicant should be approved can also help lenders understand how risk changes throughout the customer lifecycle.
Portfolio monitoring, early warning indicators, collections prioritization, line management, and customer growth strategies all benefit from stronger predictive models. Post-origination tools like Cashflow Servicing apply the same behavioral signals used at approval to flag early risk indicators before they surface.
Rather than viewing modeling as a single origination exercise, many leading lenders are beginning to treat it as a capability that supports decision making across the entire lending lifecycle.
This broader approach creates opportunities not only to manage downside risk but also to identify customers who may be suitable for higher limits, additional products, or more personalized servicing strategies.
At Carrington Labs, we believe the industry's focus is gradually shifting from alternative data to alternative models.
Data will continue to evolve, and new sources will continue to emerge. But long-term competitive advantage will come from how effectively lenders transform that information into explainable, commercially valuable decisions.
That is why we build lender-specific credit models rather than generic scores.
Depending on the use case, those models may incorporate bureau data, transaction data, Open Banking, internal portfolio performance, accounting data, payroll information, or other relevant sources. More importantly, they are designed around each lender's products, customers, and objectives rather than assuming one model fits every institution.
Some lenders need an explainable transaction-based credit risk score, such as Cashflow Score, to complement their existing decision engine.
Others require a fully customized probability-of-default model, like our Credit Risk Model, trained on their own historical performance.
Others are looking to optimize loan amounts and pricing with a tool such as the Credit Offer Engine, or to monitor portfolios post-origination.
These are different challenges.
They deserve different models.
As alternative data becomes more widely available, competitive advantage is increasingly moving away from data acquisition and toward better decision making.
For credit risk leaders, that raises several important questions:
For many lenders, answering these questions will deliver significantly more value than simply integrating another data source.
Alternative data has become an essential part of modern lending.
That debate is largely settled.
The next frontier is building models that make better use of that information.
The lenders that outperform over the coming decade are unlikely to be those with access to the largest collection of datasets. They will be the lenders that develop the strongest understanding of how those datasets relate to risk, profitability, and customer outcomes within their own business.
Alternative data provides the raw material.
Better models create the competitive advantage.
And increasingly, that competitive advantage will belong to lenders who treat modeling not as a commodity, but as a strategic capability.
