Banking, Lending & Fintech Data

Loan decisions with repayment outcomes, fraud investigations and compliance reviews, de-identified and aggregated.

Evaluate Your Data Request this type of data

Financial datasets for AI are de-identified records of real banking decisions with known outcomes: loans approved or declined and then repaid or not, fraud alerts and how they ended, and compliance reviews. AI teams use them to train and test credit, fraud and compliance models. Public market data is easy to buy; outcome-linked banking records are not. DataNexx helps institutions license de-identified or aggregated extracts.

Why it matters for AI

Recorded, judged, resolved.

Lending data is valuable because the outcome is known: a decision was made and, months later, the loan was repaid or not. Only de-identified or aggregated extracts are considered, with the institution's written authorization and its own privacy and confidentiality review — never raw customer files.

Guide

Which systems hold banking and lending data?

The core banking system holds accounts, balances and transactions. The loan origination system holds applications, risk inputs and decisions. The servicing and collections systems hold repayment behavior. Fraud and AML case tools hold alerts, investigations and outcomes.

The outcome is what makes these records valuable. A credit decision means little until you know whether the loan was repaid.

Fraud alerts with the investigator's finding
KYC reviews with the decision and the reason
Collections and restructuring results

What do AI teams build with financial datasets?

Teams train underwriting and credit-risk models on decisions with outcomes. They train fraud detection on confirmed cases, including the false alarms. They build compliance assistants that draft a review the way an analyst would.

Evaluation is a big use too. A team can test a model against cases where the real outcome is already known.

Service records add a softer view. A customer request, the steps an agent took and the final resolution show how a bank actually handles a problem.

Which privacy and secrecy rules apply to financial data?

Banking data is among the most regulated data there is. In the US, the Gramm-Leach-Bliley Act (GLBA) limits how financial institutions share customers' nonpublic personal information. Card data falls under the PCI Data Security Standard, so card numbers and security codes are never included. Bank secrecy rules go further: suspicious activity reports, and anything that would reveal one exists, cannot be disclosed at all.

So only de-identified or aggregated extracts are considered, never raw customer files. Each extract needs the institution's written authorization and its own privacy and confidentiality review. Your compliance team and counsel decide what is in scope.

How does an institution prepare a first description?

Start with a short description. No customer data is shared at this stage.

Example record (illustrative)

Illustrative record: a fictional, de-identified small-business loan. Not a real customer.
Field	What it holds
Product	Unsecured small-business term loan
Risk inputs	Banded revenue, time in business and sector; no names or IDs
Decision	Approved at a reduced amount, with the underwriter's reason code
Repayment history	Monthly status: on time, one late payment, then on time
Final outcome	Repaid in full at term
Transformations	Customer identifiers removed; amounts and dates banded

Frequently asked questions

What are financial datasets used for in AI?

Mostly credit-risk, fraud detection and compliance models. Records with known outcomes are used both to train these models and to test them.

Do you take raw customer files?

No. Only de-identified or aggregated extracts are considered, with the institution's written authorization and its own privacy review.

Are suspicious activity reports included?

Never. Bank secrecy rules bar disclosing a SAR or any information that would reveal one exists. Card numbers and security codes are excluded too.

Is this market or trading data?

No. This page covers operational banking records, such as lending, fraud and compliance decisions. It does not cover market feeds or trading data.

How quickly do you respond to an enquiry?

We reply within 24 hours. The first step is a short description, not a data transfer.

Which institutions hold financial datasets?

Banks, credit unions, consumer and small-business lenders, payment and fintech companies, and microfinance institutions with long loan books.
