Account Aggregator Interoperability Boosts Indian Finance

The Reserve Bank of India (RBI) announced on 7 October 2026 that it will permit account aggregator interoperability. This move lets customers share their financial data across any approved aggregator, widening choice and streamlining credit checks.

What account aggregator interoperability means

Under the new framework, a user who has linked their bank accounts, mutual funds and insurance policies to one AA can now switch to another AA without re‑authorising each source. The RBI calls this a “consent‑based, cross‑provider” model, aimed at creating a unified view of assets for lenders and other service providers.

Account aggregator interoperability is designed to break the data silos that have traditionally limited consumers to a single data conduit. By allowing seamless migration between aggregators, the RBI hopes to foster competition, improve service quality, and reduce the friction that borrowers face when seeking credit.

Impact on NBFCs and credit assessment

Non‑bank financial companies (NBFCs) will be able to request data directly from any AA, provided the customer gives explicit consent. The new framework aims to reduce loan processing times and lower default risk by providing lenders with a fuller picture of borrowers’ financial health.

With account aggregator interoperability, NBFCs can integrate multiple data streams—bank statements, tax filings, and investment portfolios—into a single risk‑scoring engine. This holistic view is expected to improve underwriting accuracy and expand credit access for underserved segments.

Steps for account aggregators

All existing AAs must upgrade their APIs to comply with the RBI’s interoperability guidelines. The central bank has set a deadline of December 2026 for completion. Failure to meet the timeline could result in the loss of AA licence.

Technical upgrades include implementing standardized consent‑management protocols, enhancing encryption standards, and supporting real‑time data retrieval across the ecosystem. Account aggregator interoperability also requires robust audit trails to satisfy regulatory oversight.

Benefits for consumers

Consumers gain greater control over their data and can choose the aggregator that offers the best user experience or lowest fees. The move also supports financial inclusion by making it easier for underserved segments to prove creditworthiness.

In addition, account aggregator interoperability empowers users to revoke consent from any aggregator at any time, reinforcing privacy safeguards and building trust in the digital finance landscape.

Market reaction

Shares of fintech players such as Pine Labs rose after the announcement, reflecting investor optimism about a larger addressable market for data‑driven services.

Businesses that rely on asset statements—loan platforms, wealth‑tech firms and insurers—are expected to redesign their onboarding flows to tap the new data streams.

While the RBI has not disclosed exact numbers of participating AAs, the policy note indicates that both existing and new entrants will be eligible, provided they meet technical and security standards.

Customers should watch for notifications from their chosen AA about upcoming updates. Once the system is live, users will be prompted to grant consent before any data is shared with a new provider.

Regulatory framework supporting interoperability

The RBI’s guidelines for account aggregator interoperability build on the existing Account Aggregator (AA) model, which was introduced in 2020. The new rules mandate stricter data‑privacy norms, periodic security audits, and a clear escalation path for grievance redressal. By codifying these requirements, the regulator aims to create a predictable environment for both aggregators and data‑consuming entities.

Technical requirements for AAs

To achieve interoperability, AAs must adopt the OpenAPI specification released by the RBI, support OAuth 2.0 for consent management, and implement end‑to‑end encryption for all data transfers. The guidelines also prescribe a maximum latency of 2 seconds for data retrieval, ensuring that downstream applications such as loan origination platforms receive information in near real‑time.

Consumer privacy safeguards

Privacy remains a cornerstone of account aggregator interoperability. Consumers can view a consolidated consent dashboard that lists every entity that has accessed their data, the purpose of access, and the duration of consent. They can revoke permissions with a single click, and the system must honor revocation within 24 hours.

Future outlook

Analysts anticipate that account aggregator interoperability will pave the way for new fintech innovations, including AI‑driven credit scoring models, real‑time income verification for gig workers, and cross‑border data sharing for NRIs. As more players enter the ecosystem, competition is expected to drive down fees and improve user interfaces, further enhancing financial inclusion across India.
