Account Aggregator

Overview

An Account Aggregator is a regulated data access framework that lets customers permission third parties to securely fetch financial data from multiple institutions in a standardized format. Aggregators act as consent managers, not data warehouses, brokering encrypted transfers between data fiduciaries such as banks and data users such as lenders or fintechs. In KYC and underwriting, this enables real time income, cash flow, and liability insights without uploading statements.
Strong programs log explicit, granular consent, minimize requested scopes, and enforce time bound access with revocation. Governance covers provider due diligence, encryption, key rotation, and audit trails of every data pull. When orchestrated with ID verification and risk scoring, account aggregation speeds onboarding, reduces document fraud, and improves affordability assessments while maintaining customer control and regulatory compliance.

FAQ

How does an Account Aggregator improve onboarding?

It replaces manual statements with permissioned, real time data pulls, cutting errors and review time while producing structured cash flow and liability insights for decisioning.

What are the privacy controls?

Customers grant explicit scopes and durations, can revoke at any time, and data flows are encrypted end to end with provider audits and access logs for transparency.

Is data stored by the aggregator?

Reputable frameworks pass data through rather than store it. Institutions should verify retention policies and ensure only necessary attributes are ingested and retained.

How is consent proven to auditors?

Store consent artifacts, timestamps, scopes, and transaction IDs. Tie each data field to a consent record and maintain revocation logs for traceability.
