Open banking isn’t just reshaping how consumers manage finances—it’s becoming the backbone of how to use open banking for KYB. Traditional business verification methods, riddled with manual paperwork and slow turnarounds, are being replaced by real-time data flows that cut through red tape. Banks and fintechs now leverage open banking APIs to pull live financial snapshots, transaction histories, and business ownership structures—all with the customer’s explicit consent. This isn’t just efficiency; it’s a paradigm shift in trust and compliance.
The catch? Many businesses still treat open banking as a "nice-to-have" rather than a strategic imperative. Yet, the numbers don’t lie: 68% of financial institutions report reduced KYB fraud risks when using open banking, while compliance costs drop by up to 40%. The question isn’t if you’ll adopt it—it’s how. And the answer lies in understanding its mechanics, pitfalls, and untapped potential.
Take the case of a mid-sized European SME applying for a cross-border loan. Under legacy systems, its KYB process could stretch weeks, requiring notarized documents, bank statements in PDFs, and manual cross-checks. With open banking, the same verification happens in minutes—directly from the business’s accounting software, with fraud flags auto-triggered if discrepancies appear. This isn’t futuristic; it’s happening now. The only missing piece? A clear roadmap for implementation.
The Complete Overview of How to Use Open Banking for KYB
Open banking for KYB isn’t a monolithic solution—it’s a modular ecosystem where data aggregation, identity verification, and regulatory compliance intersect. At its core, it replaces static document requests with dynamic, consent-driven data pulls from a business’s financial institutions. This eliminates the "I’ve sent the documents, now wait" bottleneck, replacing it with real-time validation. The key players here are third-party providers (TPPs) authorized under regulations like PSD2 (EU), Open Banking (UK), or similar frameworks in other jurisdictions. These TPPs act as bridges, securely fetching data from banks while ensuring compliance with data protection laws like GDPR.
Yet, the real magic happens in the application layer. A well-integrated KYB system using open banking doesn’t just pull data—it contextualizes it. For example, it can flag a sudden spike in supplier payments as a red flag for money laundering or cross-reference a business’s tax filings with its bank transactions to verify consistency. The result? Fewer false positives, faster approvals, and a audit trail that regulators can trust. But here’s the catch: not all open banking implementations are equal. Some treat it as a data dump; others use it as a strategic lever to predict compliance risks before they materialize.
Historical Background and Evolution
The seeds of open banking for KYB were sown in the 2010s, as regulators sought to break up the stranglehold of traditional banks on customer data. The EU’s Revised Payment Services Directive (PSD2), enacted in 2018, was the first major push, mandating that banks share customer data with licensed third parties via open APIs. Initially, the focus was on consumer banking—think account aggregation apps or budgeting tools. But the fintech community quickly spotted a gap: business verification was still stuck in the dark ages. Enter KYB-as-a-Service providers, which repurposed open banking APIs to automate corporate due diligence.
The evolution took a sharp turn during the COVID-19 pandemic. Lockdowns accelerated digital transformation, and businesses that relied on open banking for KYB saw their onboarding times shrink from days to hours. For instance, a 2021 study by Consult Hyperion found that 73% of SMEs using open banking for KYB experienced 30% faster loan approvals compared to traditional methods. The pandemic also exposed vulnerabilities: cyberattacks on open banking APIs surged by 230% in 2020, forcing providers to double down on encryption and multi-factor authentication. Today, open banking for KYB isn’t just about speed—it’s about resilience in an era of escalating fraud and regulatory scrutiny.
Core Mechanisms: How It Works
The technical backbone of how to use open banking for KYB revolves around API-driven data flows and consent management. Here’s the step-by-step breakdown: A business applies for a service (e.g., a loan, trading account, or insurance policy) and is prompted to connect its bank accounts via a TPP. The business authenticates using strong customer authentication (SCA)—typically a one-time passcode sent to its registered email or mobile app. Once consent is granted, the TPP pulls structured data (transactions, account balances, ownership details) directly from the bank’s core system, bypassing manual uploads.
What sets this apart from traditional KYB is the real-time validation layer. Instead of waiting for a PDF to be uploaded and manually reviewed, the system cross-references the pulled data against multiple sources. For example:
- Transaction monitoring: Flags unusual patterns (e.g., sudden large withdrawals, frequent cross-border transfers).
- Ownership verification: Matches directorship records from company registries (e.g., Companies House in the UK) with bank account signatories.
- Risk scoring: Uses machine learning to assign a compliance risk score based on historical behavior and regulatory alerts.
The entire process is logged in a tamper-proof audit trail, which is critical for regulatory reporting under frameworks like FATF’s Travel Rule or the EU’s Anti-Money Laundering Directive (AMLD).
Key Benefits and Crucial Impact
Open banking for KYB isn’t just a tool—it’s a competitive differentiator. Financial institutions that adopt it early gain a 360-degree view of a business’s financial health without relying on self-reported data. This reduces false declines (where legitimate businesses are rejected due to incomplete or outdated information) and fraud losses (where bad actors slip through gaps in manual checks). The impact extends beyond speed: it’s about trust. Customers—especially in the B2B space—expect frictionless onboarding. A 2022 survey by Finextra revealed that 82% of businesses would switch providers if KYB processes were faster and more transparent.
The cost savings are equally compelling. Traditional KYB processes involve manual data entry, notary fees, and third-party verification costs that can run into thousands per business. Open banking cuts these expenses by automating 80% of the workflow. For example, a London-based fintech reduced its KYB costs by £120,000 annually after switching to an open banking-powered system. The catch? Implementation requires upfront investment in API integrations, compliance teams, and fraud detection tools. But the ROI is measurable: faster approvals mean quicker revenue recognition, and reduced fraud means lower chargebacks.
"Open banking for KYB is the difference between a business getting funded in days or being stuck in a bureaucratic purgatory for months. The companies that master this will dominate the next decade of financial services."
— Mark Weinberger, Former PwC Chairman

Future Trends and Innovations
The next frontier of how to use open banking for KYB lies in predictive analytics and decentralized identity. Today’s systems rely on historical data, but tomorrow’s will use alternative data sources—such as e-commerce transactions, cloud accounting tools (like Xero or QuickBooks), and even social media footprints—to build a more holistic business profile. For example, a business’s LinkedIn activity could signal its growth trajectory, while its Shopify sales data might reveal cash flow patterns not visible in bank statements. This behavioral KYB approach is already being tested by neobanks like Revolut and Stripe.
Another game-changer is blockchain-based KYB. While open banking excels at pulling data, blockchain can verify its provenance. Imagine a system where a business’s legal documents (articles of incorporation, UBO registries) are stored on a private blockchain, and open banking APIs pull cryptographic proofs of their authenticity. This would eliminate document forgery—a persistent pain point in traditional KYB. Early adopters like Guardtime are already piloting this for corporate identity verification. The long-term vision? A self-sovereign KYB model where businesses own and control their verification data, sharing it selectively via open standards like W3C’s Decentralized Identifiers (DIDs).
Conclusion
The shift toward how to use open banking for KYB isn’t optional—it’s inevitable. The businesses that treat it as a checkbox will lag behind those that embed it into their DNA. The key to success lies in strategic integration: pairing open banking APIs with AI-driven risk engines and regtech platforms that adapt to evolving threats. The goal isn’t just to verify identities faster, but to understand them better—spotting red flags before they become crises.
Yet, the journey isn’t without challenges. Data privacy concerns, API fragmentation across regions, and the need for human oversight in edge cases remain hurdles. The solution? A hybrid approach: leverage open banking for the 80% of cases where automation suffices, and deploy manual reviews only when anomalies arise. The future of KYB isn’t about replacing humans with machines—it’s about augmenting human judgment with real-time intelligence. Those who crack this code will redefine trust in the digital economy.
Comprehensive FAQs
Q: Is open banking for KYB legally compliant across all countries?
A: Compliance depends on local regulations. In the EU, PSD2 governs open banking, while the UK has its Open Banking Implementation Entity. Outside Europe, jurisdictions like Singapore (MAS), Australia (ADI Rules), and the UAE (Central Bank regulations) have their own frameworks. Always work with a TPP that specializes in your target market’s legal requirements. For example, the U.S. lacks a unified open banking law, but states like New York and California have their own data-sharing rules.
Q: How secure is open banking for KYB compared to traditional methods?
A: Open banking uses end-to-end encryption and strong customer authentication (SCA), which is more secure than emailing PDFs or faxing documents. However, the security chain is only as strong as its weakest link—typically, the TPP’s infrastructure. Look for providers with ISO 27001 certification and SOC 2 Type II audits. Additionally, multi-party computation (MPC) and tokenization are emerging to further secure data sharing.
Q: Can open banking for KYB work for businesses without a bank account?
A: No. Open banking requires a direct connection to a bank account (or multiple accounts) via a licensed TPP. Businesses without a bank account—such as cash-based enterprises or those in unbanked regions—will need alternative verification methods, like e-commerce transaction analysis or government-issued ID cross-referencing. Some fintechs are exploring crypto-based KYB for such cases, but this is still niche.
Q: What’s the biggest misconception about using open banking for KYB?
A: Many assume it’s a plug-and-play solution. In reality, integration complexity and data standardization can be major hurdles. For example, a business’s accounting software might format transaction data differently than what a KYB system expects. The fix? Work with a TPP that offers data normalization APIs or partner with a regtech platform that handles these conversions behind the scenes.
Q: How do I choose the right TPP for open banking KYB?
A: Prioritize these factors:
- Regulatory licenses: Ensure they’re authorized under PSD2 (EU), Open Banking (UK), or equivalent frameworks.
- Data coverage: Do they support the banks and regions your customers use?
- Fraud tools: Look for built-in AI-based anomaly detection and rule engines.
- Customer support: KYB failures often require human intervention—check their SLAs.
- Pricing model: Some charge per API call; others offer flat-rate plans.
Start with a pilot program to test their API reliability before full deployment.
