Lending & fintech

Which applications can a rule decide, and can you show the reason for each one?

For lenders, fintechs and the operations teams behind them. Credit policy is written down; the hard part is applying it the same way every time and showing the specific reason behind each decision.

What to compile, what to keep on a model, what to leave alone

Typical calls, not a verdict on your workflow. The Workflow Diagnostic decides yours, on your own cases.

  • Credit-policy eligibility with reason codes

    Compile into code

    Your credit policy is already rules. Compiled into code, each decision carries the specific reason it was made, ready for an adverse-action notice.

  • Income and affordability rules

    Compile into code

    Thresholds and calculations that must give the same answer for the same file, every time.

  • KYC and KYB document checks

    Keep with an AI model

    Reading identity and company documents is language and image work. A model extracts the fields inside a schema; the pass/fail rules run as code.

  • Exceptions and appeals

    Don’t automate

    A person decides, with the full decision trace in front of them.

What your regulator or auditor will ask

  • Under ECOA and Regulation B (12 CFR 1002.9), a creditor that denies credit must give the specific principal reasons. Saying the applicant failed the creditor’s scoring system is not enough, whatever model made the decision.

  • In April 2026 the Federal Reserve, OCC and FDIC issued revised interagency model risk management guidance (SR 26-2), replacing SR 11-7 (2011).

  • Under the EU AI Act (Annex III point 5(b)), AI used to evaluate the creditworthiness or credit score of natural persons is high-risk, except AI used to detect financial fraud. Under the 2026 Digital Omnibus agreement, Annex III obligations apply from 2 December 2027.
