Open Banking Is Quietly Rewriting How Loans Work
It started with a simple shift: let consumers share their financial data. What followed was a slow but significant reset in how lenders make decisions…
Open Banking gives lenders access to real-time banking data through APIs—spending patterns, income flows, and financial habits. It’s no longer about guessing who’s creditworthy. It’s about seeing it.
For decades, lenders operated with outdated or incomplete views of borrowers. Now, they can assess a financial life as it actually unfolds—transaction by transaction, paycheck by paycheck. And that changes everything.
This shift is rewriting how creditworthiness is judged. And for borrowers, that’s the difference between being declined and being understood.
What’s Actually Changing in Lending via Open Banking
Long before banks or credit scores, there were clay tablets and promises. In ancient Sumeria, more than 5,000 years ago, the first recorded loans were scratched into stone—grain borrowed, livestock lent—all on the faith that it would one day be repaid. The question then was simple: Will this person pay me back?
Fast forward to today, and lenders ask the same question—but in far more complex ways. Algorithms, credit bureaus, scoring models. We’ve wrapped the ancient question in data. And yet, the result is still often inadequate. Millions of people—freelancers, migrants, gig workers, young adults—are routinely shut out of the financial system. Not because they’re risky. But because the system can’t see them clearly.
Forget about traditional credit scores for a minute. Lenders are now looking at live transaction histories. They can see if your income is stable, if you consistently pay your bills, and how you actually manage money—not just how you appear on paper.
That means more tailored loan offers. Lower interest rates for people with strong cash flow—even if they’ve never had a credit card (Nam, 2022). Flexible repayment terms for freelancers or gig workers. And actual access for people who’ve long been ignored because they didn’t fit the system.
1. Credit Scoring Grows Up
Traditional credit scores are blunt instruments that often rely on static indicators, which can misrepresent an individual's true financial health. Open Banking replaces the proxy with pattern recognition. Lenders can now assess income volatility, expense categories, overdraft frequency, and even behavioural signals like spending spikes or cash flow stress. It’s a shift from “score-based” to “data-aware” lending. And it's already improving default predictions—especially for gig workers and non-salaried earners who legacy models often misjudge. A study on open banking's impact in the BRICS countries found that the advent of open banking regulations significantly reduces the amount of consumer loan lending by traditional banks after implementing such regulations (Fang and Zhu, 2023).
2. Smarter Offers, Better Terms
With richer data comes sharper pricing. Lenders can segment risk more precisely, which unlocks better terms for low-risk borrowers—regardless of their credit history. For some, it means access to loans they wouldn’t have qualified for at all. For others, it means lower interest rates, tailored repayment schedules, or dynamically adjusted credit lines based on current financial health. In the U.S., the Consumer Financial Protection Bureau's new open banking rules aim to facilitate such personalised financial services by mandating that banks share consumer data with authorised third parties, enhancing competition and potentially leading to better loan conditions for consumers (Reuters, 2024).
3. Access for the Underserved
Half the world’s adult population—some 2.5 billion people—remains outside the reach of formal financial systems. According to the World Bank, nearly 75% of the world’s poorest people don’t have a bank account. Not because they don’t want one, but because the system was never built for them. No fixed income. No credit history. No passport to traditional lending (World Bank, 2025). Millions of people have been locked out of formal lending because they don’t have a thick credit file—think new immigrants, freelancers, or young professionals. Open Banking gives them a financial identity built on real-time cash flow instead of static metrics. That means real access—not predatory payday traps, but loans that reflect how they live, earn, and spend. In markets with high financial exclusion, this is a structural unlock.
People with “thin files” have a way in for the first time.
But It’s Not All Smooth – Challenges to Open Banking & Lending
The usual concerns are still there: data privacy, API security, and consumer trust. Most people don’t fully understand what they agree to when connecting their bank accounts to a third-party app. And many lenders still operate in regions where Open Banking laws are patchy or non-existent.
And then there’s the real challenge: making this work at scale without turning it into another data grab (Deloitte, 2025).
1. Data Privacy and Security
Open Banking depends on consumer consent, yet most users barely understand what they agree to when they approve a data connection. That creates exposure, especially when third-party apps use opaque terms or weak encryption. Until consent is paired with clarity—and security is baked in, not bolted on—this remains a critical weak spot.
More fundamentally, data security cannot be an afterthought. It must be embedded into product architecture from day one—baked in, not bolted on. Anything less puts the credibility of the entire ecosystem at risk.
2. Regulatory Inconsistency
Some regions have mature, enforced Open Banking frameworks (e.g., the UK’s PSD2). Others have fragmented rules or none at all. For global lenders or fintechs operating across borders, this creates friction and legal ambiguity. Who’s liable when something breaks? What happens when APIs don’t meet baseline standards? The promise of real-time underwriting runs into reality: inconsistent pipes, patchy enforcement, and limited interoperability.
Until regulators harmonise standards—or industry leaders converge on common protocols—the full promise of Open Banking will remain just out of reach. What we’re building is powerful. But right now, it’s also fragile.
What It Means…
Open Banking is making lending less about what the system thinks you are, and more about what your financial life actually looks like. That’s a quiet revolution.
And when you pair that data with machine learning, we’re talking about personalised lending that adapts in real-time. Not someday. Now.
The real question is: will traditional lenders move fast enough, or will the fintechs run the table while they debate risk committees and legacy systems?
We're no longer short on data—but we’re still short on understanding. The tools that power financial access haven't kept pace with how people live, earn, or spend. And until they do, the credit system—5,000 years in the making—will remain broken for far too many.
Where Gen AI Fits into the Open Banking Stack

With access to transaction data through Open Banking, these systems offer investment advice that’s not only tailored, but timely. They don't just ask how much you earn—they know when you splurge, when you're stressed, and when you’re saving.
2. Automated, Smarter Lending - Loan applications are historically rigid. You apply, wait, and hope. But with AI models trained on Open Banking data, approvals can be near-instant—and more accurate. Generative AI can synthesise your spending habits, income volatility, and repayment behaviour to assess risk far beyond a FICO score. This leads to faster decisions, fairer rates, and dramatically lower overhead for lenders. For borrowers, it means less waiting and fewer black-box rejections.
3. Predictive Financial Health Engines - Your bank knows when your balance hits zero. But Gen AI knows why. By analysing patterns in your bills, subscriptions, and income gaps, it can anticipate financial strain before it happens—and offer preventive solutions. Whether it’s nudging you to move money between accounts or offering a pre-approved emergency credit line, AI becomes less reactive and more like a safety net in motion.
4. Hyper-Personalised Engagement - Forget blast emails and banner ads. With generative AI, banks can craft individualised messages at scale—tailoring product offers, educational content, and repayment advice to each customer’s behaviour. It’s not just about knowing that you took a vacation—it’s about offering a smarter savings plan for the next one.
Open Banking & the New Era of Lending
Open Banking gives lenders real-time visibility into spending patterns, income flows, and financial behaviour—making lending decisions more accurate, more inclusive, and more dynamic. For borrowers, this unlocks more than just access. It brings lower interest rates, smarter repayment terms, and a genuine chance to be understood, not just scored.
Data sharing, when voluntary and secure, is proving to reduce adverse selection and boost approval rates without raising default risk.
The interface becomes invisible. The decision becomes real-time. The opportunity becomes global. With generative AI layered in, the benefits multiply: from hyper-personalized financial advice to real-time underwriting. Loans now adapt to your financial life, not the other way around.
But can design, data, and regulation align to deliver access without compromise? Because the technology is already here.
