Credit portability in open finance: what IAM teams need to watch

TL;DR: Brazil’s credit portability pilot is showing how consent-based APIs, accredited participants, and regulated settlement can move loan transfers from weeks to as little as five days, with Open Finance Brasil already processing more than 102 billion API calls and nearly 62 million active consents in 2024 according to Raidiam. The governance lesson is that portability at scale depends on identity assurance, not just cleaner workflows.

By the numbers:

• Open Finance Brasil saw record-setting adoption in 2024, processing more than 102 billion API calls.
• The Credit Portability API entered its production pilot phase in November 2025.

Questions worth separating out

Q: How should organisations govern credit portability in open finance ecosystems?

A: Organisations should govern credit portability as a shared identity and consent problem, not only a transaction workflow.

Q: Why do open finance portability models increase IAM requirements?

A: Open finance portability increases IAM requirements because trust must extend across institutions that do not share a single internal security boundary.

Q: What breaks when participant offboarding is not part of portability governance?

A: When offboarding is missing, former participants can retain access paths through APIs, certificates, or delayed revocation processes.

Practitioner guidance

• Map the participant trust chain end to end Document which identities can request credit portability, which can approve consent, and which can settle the transaction.
• Tie consent scopes to access lifecycles Make consent expiry, entitlement review, and revocation validation part of the same operational workflow.
• Separate onboarding assurance from steady-state assurance Use onboarding checks to verify eligibility, then add continuous controls for API activity, certificate validity, and participant drift.
